What is your current yard temperature?

[sandgroper]

Currently 14c at 7.30am heading for 24c.

[UK_Palms]

The heatwave has sort of come to an end. I am only reading 27.2C / 80F here at 2pm today, after 7 consecutive days above 30C / 85F and 4 consecutive days above 32C / 90F.

Some very, very warm nights too. Lows only dropping down to 23-24C at street level in central London on Friday night. Saturday night was pretty similar. These are the 1-2am temps on Friday night…

The heat peaked on Saturday with 33.2C / 93F being recorded at Kew Gardens in London. This was also the hottest day of the year, which shows how poorly July and August did this year.

 

Max of 32.5C / 93F in Cambridge yesterday. Heathrow and Kew Gardens also reached 32C / 90F. That was the 7th consecutive day over 30C / 85F in the UK, which also included 4 consecutive days of 32C / 90F or greater.

St James Park in London now has an average September max of 29.3C across the first 10 days of September. This is more akin to the first 10 days of January in Perth, WA @Tyrone @sandgroper

I was in London yesterday and the heat and humidity was unbearable, especially when it clouded over. No rain however. Battersea park was looking very, very dry. For me here, I haven’t recorded a drop of rain this month and only 1.9mm / 0.07 inches since mid-August now.

Still looking fairly warm and dry moving forward. Potentially a return to 30C+ temps again towards the end of the month.

January in Perth averages around 32C. 29C for the first ten days of January in Perth would be mild. You’re generally hitting high 30s to low 40s by then. Still, London is looking more like Geraldton in summer than I remember seeing it. It’s dry and straw coloured. Not green at all. 

[Arecaceus]

This recent phase of September weather has been extremely sunny. I haven't seen a single cloud for a while now. Clear skies all day, all night. Deep blue skies. Just amazing. Highs always between 30 and 33°C. Lows were also very mild with 17 to 20°C every night. Today's been the hottest with a high of 34.5°C and a low of 19.0°C. This night or tomorrow we might get some thunderstorms if they don't die over France before. After that sunny weather seems to come back with milder temperatures. ☀️🌡️🥰

[Silas_Sancona]

Touch hot, but not bad under partly cloudy skies as we wait to see if we'll get -any- rain over the next 28-48 hours..  Regardless, doesn't look like much for the deserts if we do. Not overly impressive potential rainfall totals for the mountains / S.E. AZ either..



A slight rise in temps as we head into next weekend, but still in the " normal for September " range..  If it holds, next week looks NICE.. Esp the low 70s ( Possible upper 60s ..Suggested by some forecasts anyway )

Far better than this past weekend which make it ..55days above 110F for the year < 53 was the previous record, in 2020 > / 36 days of lows at/ ABOVE  90F.  Previous 90 / 90+ lows record was ..28 days. Though they don't count, expect to me, lol.. Some 115F+ readings on neighborhood Wx stations yesterday as well. Yuck.. Hopefully, yesterday was the end of that.



Something else not seen in quite sometime:  ...A ~mostly~  advisory-free ( Heat-related products esp ) map across the entire country..  ..That's a good thing, lol.

[sandgroper]

@UK_Palms I'll take a nice cool 29c anytime for the first 10 days of January, trouble is that would be very uncommon. I'll post up the first 10 days of the coming January so you can see the difference between Perth and London, you may be surprised.

[DTS]

cold

[UK_Palms]

@Tyrone @sandgroper Yeah, my bad. You are both right. I have checked the averages and most of Perth is around 32C in January. It is actually warmer then almost anywhere in Europe during July, except places like Athens and Seville. I forgot just how hot it gets there in Perth.

However, I have looked at the first 10 days of March (equivalent to September here) and for the first 10 days of March 2023 at the Fremantle station it averaged 27.7C, which is 1.6C lower than the first 10 days of September at St James Park, London (29.3C). I should have made that comparison rather than with January, which is during mid-summer for you guys.

Anyway, it is much cooler now, but still fairly mild/warm. I will still be in t-shirt and shorts for the foreseeable. London will be 26C / 78F on Friday. Currently 23.7C here at midday right now today. Maybe some rain coming this week, which will be my first in weeks. Hopefully it is decent next week though when I am in the Isle of Wight.

[Foxpalms]

Sunday: Min of 71f/21.6c with a max of 90f/32.2c with 47% humidity due to cloud cover all day then thunderstorms nearby. The rain and thunderstorms though missed here and was just west of London around Reading. Monday's low was 68f/20c with a max of 80.6f/27c with 50% humidity.  Low this morning was 69f/20.5c at 5.35am.  The rest of this week doesn't look too bad considering it's Autumn/fall here and the sun is noticeably weaker than it was even a few weeks ago. Personally I think for the weekend the Metoffice is understating the temps. Gfs runs are showing around 27-28c.

Edited September 12, 2023 by Foxpalms

[Foxpalms]

@UK_Palms Perth during the summer is fairly similar to costal parts of Europe South of 41N. Nowdays inland areas such as Seville have been quite a bit hotter than the older averages suggest. This year Seville's average high for July was 100f/37.7c and last year it was even hotter. These costal parts of Europe in recent years have also been hotter than the averages suggest.

85F under partly cloudy skies w/ a touch of humidity and a breeze as some storms roaming the desert to the south head east...

Morning True color satellite view:



Will we ..or won't we see  additional activity this afternoon / evening?? ..That is the question.. More clearing to aid in proper insolation to help destabilize the local atmosphere?  better odds for storms.. Less breaks in the clouds to help heat things up?  maybe less activity.  We'll see..

A marginal risk for ..mainly larger hail and wind..   across the region toady, ..if.. storms get going..



Rest of the week / beyond still looks  ...typical for mid September..

[Palm Sundae]

Kind of a stormy day all day. The ground got a little wet. Looks like we'll wind up with about half the average Monsoon rainfall this year, give or take. After more than double each of the last two years it doesn't seem right to complain - but I will just a little.

Looking forward to overnight lows in the 60's starting next week, along with the end of 100+ highs. (Well... could see stray higher temps.... but it is mid-Sept)

[sandgroper]

The bottom south West corner of our state is currently in the middle of a fairly nasty storm front, the storm is 4 times the size of the UK.  and is causing some grief. There's a lot of heavy rain and strong winds, some recorded over 125kms an hour.

[greysrigging]

Been a warmish 5 day spell at Darwin Airport

But there are benifits... the Caladiums love the heat !

[Silas_Sancona]

91F at 11:58AM after a pretty wild night /early AM  ..in some parts of town at least..

Forecast for storms panned out, though most of the stronger activity was confined to areas north of the U.S. 60 ( See the maps below ) 

That said, storms that did roar across effected areas, left quite a bit of damage, especially in /around Mesa. 

**** Getting ahead of any rumors, before they are spread,  NO.. there were no Tornadoes in areas that suffered damage last night, esp here in the east valley.  Arm Chair casual weather watcher " thoughts" aside,  ..if the NWS / SPC did not record and document one, No tornado(es) occurred anywhere  in the valley..

That said,   watching the same storms / noting storm-type characteristics,  i'm certain there were severe downburst wind events which generated the 65-90-something wind gusts recorded on that side of town / a few other areas on the west side causing the damage being reported extensively on local news stations this morning. *****

Using the storm that we did see roll through the neighborhood earlier in the day  yesterday,  it had several characteristics of ..what is often called a " low precipitation " supercell..  Tall, Narrow profile, well defined, -but small-  base ...w/ minimal rotation,  large hail,  some of which fell at the house as it passed overhead ..very strong, - but brief-  winds as it passed,  and about on hour of non-stop thunder in the clouds.  Only thing missing were cloud to ground strikes,  which, had the storm produced them, likely would have zapped everything in the neighborhood as the cell passed overhead.

Anyway, that was a pretty solid clue any additional storms that could occur thru the rest of the day / into /overnight could also turn severe quickly / exhibit supercell-type characteristics,  even if moving through a given area pretty rapidly.    ..Is exactly what occurred.



As for today?? ..we have more chances, though it will be interesting to see where storms set up.. Could form just west of Phoenix before moving through, or east of where i'm located, ..more toward the foothills / mountains. Regardless, could be another active day for severe weather ( Wind, Large Hail, brief, but very heavy rain ) 






Everything shuts down later tonight into tomorrow ..and beyond..  Yesterday's forecast for the rest of the week still stands, though Saturday may be a deg. warmer ( ..104-106F ) than what forecasts were suggesting yesterday.. We'll see..  Cools down by Monday again next week, w/ the season's first sub-70F low on the extended forecast maps at that time.

Places like Flagstaff, other areas up in the mountains / Rim, may see fall-like  70s / lows in the 40s next week also.




Circling back to rainfall totals yesterday/ last night.. You can see who got rain, and who did not.  You can also see that Sky Harbour got ..pretty much nothing..   As of this morning, their rainfall total -for the entire Monsoon, stands at  0.15"  For now, there is no more rain in the extended forecast. If they get nothing this afternoon / early evening ..let alone over the next 2-ish weeks before the season ends, this will be the driest summer ever recorded.

While many other areas of town have done better ..pretty good in a few spots even,    the overall valley average is well below what is normal during Monsoon Season as well.






Looking even further out, very possible an early taste of fall pays both California and AZ a visit sometime after the 20th.. Some GFS model runs have been hinting at a couple stronger troughs digging down into / across the southwest / Inter-mountain West, bringing a string of morning lows in the 60s here/ lows in the lower 40s /..likely some 30s in spots,  up in the mountains ..and maybe some rain for Nor. Cal. 

Obviously, ..just forecast "thoughts" this far out,  but,   ..something to watch as Astronomical Fall  arrives..

 

[Silas_Sancona]

A comfy 80F at 10:45PM as what is left of the past week's humidity / higher Dew points finally gets scoured out... 

Slightly toasty weekend ahead,   perfect for all our local neighbors celebrating Mexico's Independence Day.  

Next week? ..pretty nice, pretty average heat for the desert in early Fall Weather ahead..


If it holds, Next weekend looks really nice..   Upper 80s / lower 90s,  mid to upper 60s, maybe a few 70s in the warmer parts of Phoenix to start the day.. No rain though..



If only this was as hot as it would get here ALL  summer..

[Bill H2DB]

   Here are my conditions this morning at approx. 6 am .

[UK_Palms]

Max of 26.3C / 78F on Wednesday. It has felt much cooler than it actually is, following the very warm, humid conditions that we had last week.

 

Warmer yesterday again with temperatures reaching 27.3C / 80F here in the Guildford area where I am working.

 

Typically it is going to cool down properly next week, just when I go away to the Isle of Wight for a week! 🙄

 

 

It is getting very dry again here now though, so a bit of rain will be quite welcome, I suppose. Currently 28.1C / 82F here at 1:30pm. I am expecting at least 29C / 84F now this afternoon, maybe higher.

@UK_Palms where do you get your temperatures from? When I look at the Met office I get this.

The Metoffice does tend to understate the temps slightly but I think the forecast UK palms posted was for where I am in London not Guildford. The forecast here is a bit cooler than it was showing a few days ago around average to slightly below average for mid September bearing in mind it's always 1-2c warmer than the forecast here because of how strong the urban heat island effect is in central London.

Edited September 17, 2023 by Foxpalms

[Foxpalms]

@sandgroper Here's a comparison of a wunderground station here compared to one in Compton Guilford. I'm not sure if this one in Compton Guilford is a reliably accurate one but the one in central London definitely is.  You can definitely see how much the urban heat island influences the weather here especially at night. Though being closer to the ocean and having the river Thames also helps the night temperatures.

[sandgroper]

@Foxpalms OK, just often seems to be quite a difference between what I see quoted here and what the official Met office says. I always quote temps here from the Commonwealth Bureau of Meteorology, they're official recording station is at Perth airport so for me in Jandakot maybe its more, maybe it's less but I think their equipment is pretty accurate so despite it being 25 kms away it's good enough for me.

I don't know about Guilford but the met office here doesn't really take the urban heat island into effect as much as they should. Where UK palms is there is no urban heat island so that's a different story.  The nearest metoffice station to me is st James park however central London is extremely dense so you can feel quite a difference between a large open park and a small garden in a very dense area is the heat is just able to build a bit more plus there is less wind. The biggest difference though is at night. It really shows because kentias on park lane get some slight damage during bad winters but if you go a few streets away from the park they never have cold damage even during the worst winters. If anyone has ever been to winter wonderland in Hyde park you really feel the difference between being in there Dec/Jan when there's a breeze and its around 9c but if you walk into Mayfair even onto the first street you feel a temperature difference.  The private weather stations here near each other also record fairly similar values.  I have one of the Davis weather stations set up around 2m off the grass in the garden, so I trust that my weather station is accurate I just think London has a lot of microclimates.  The London St James park weather station is also stupidly positioned it has loads of massive trees right in front of it facing south so where its positioned will be slightly cooler than the true temperature as trees reduce the temperature.  So only during the winter months the temperature highs will be accurate as they are deciduous trees.

After a thunderstorm earlier this week, weather got sunny again. Temperatures usually around 25-28°C at day and 14-19°C at night. Today's high has been 28.8°C, low 19.4°C, warmest day since my last post. This afternoon clouds rolled in. We might get a thunderstorm or just rain tomorrow morning. Forecast looks still good. 🌥️🥰🌴

I use the Met Office site mostly. The forecast you have attached shows this coming week, when we are clearly expecting a big cool down. At least momentarily. You have also cropped out the 27/28C forecast that was showing on Saturday. London definitely reached at least 28C / 82F on Saturday just gone. We had about a 10 day period of 25-34C temperatures, which has just ended.

I am on the ferry now crossing over. The weather is bloody terrible. It looks like I have picked the worst week of the month to go, given that high pressure and warm temperatures are due to return again by next weekend. Pretty annoying and very typical. If I went either side of this week, I would have had clear, sunny skies and 25C+ / 77F+.

Last night I had a torrential thunderstorm at home with thousands of flashes, thunder and the heaviest rainfall that I have ever seen. I racked up over 40mm in the space of 10 minutes! There was almost a foot of standing water on my patio and parts of my garden. I racked up a staggering 79mm yesterday, which is my wettest day since I started recording data here. Previous wettest day was only 63mm. More thunderstorms expected over the next few days as well unfortunately.

Also I had no idea there was a Norfolk Island Pine at Ventnor. I will definitely get some photos of it. I have tons of stuff to see, so I will likely have to just make the best of the bad weather. So far it isn’t a great omen though…

[Silas_Sancona]

A very pleasant 79F at 9:31PM... Some clouds, and stayin in the upper 90's over the next few days before a minor bump to the 100-102F range early next week ..before moving back to the mid / upper 90s later ..if the current forecast holds of course..



Other than that.. Well, unless something unexpected comes out of left field, it's looking like the final stretch of Monsoon 2023 will be bone dry ..Here in the low deserts at least.. Nor. and parts of E. AZ / parts of N.M.  may see a few shower chances at times, but isn't looking widespread. ..or anything special..   We'll see of course,  but it sure looks like  the abysmal 0.15" ..yes, that is correct,  will be it for Phoenix for this year's Monsoon.  Tucson looks better, but also looks to end this season below average too ( ..as does the entire state really ) 

If anything, watching for the first  -significant-  cool down of the Fall  which may arrive by the first week of October..  Could bring our first multi-day streak of sub 70F lows, and perhaps the first stretch of mid / lower 30s for the high country..  No rain forecast  -of course, lol..

Same potential storm could bring the season's first " Hint of winter " to the Rockies,  maybe some cool season rain for parts of CA / PAC. N.W.  ...if it materializes as some bullish model runs have shown. 

Tis' the season already i guess..

 

[Arecaceus]

Monday night we got some heavy thunderstorms after a warm and sunny day. Yesterday's been pretty windy and partially cloudy. Rather cool. Today it's been very nice and sunny again with a high of 26.2°C and a low of 16.9°C. The next two days will get turbulent with the remains of Hurricane Lee. After that summer weather seems to return. ☀️

Like I've noticed before most plants in my garden love this time of the year. Much more than mid summer. Everything is growing insanely. Many things are flowering and my Gaillardia aristata is starting many new flower buds. Many more than all season. I took this picture today 🥰:

A partly cloudy 91F as " Astronomical " fall begins.. 'Nother little bump in temps for the week ahead, ..but still pretty seasonal..  ...before another tick down by next weekend ( if the current forecast holds of course )  Could get cooler than currently suggested if some of the more enthusiastic GFS runs pan out just past the current 10 day.. 



06Z " Fantasy Run "  was even suggesting a pretty potent cool down for the eastern part of the country to kick of October, complete w/ maybe a little frozen stuff showing up over the Appalachians. 12Z run is ..back to what most runs have been suggesting, for the moment anyway... = pretty much seasonal conditions across the country, except maybe in the N. Rockies where more early snow may fall  as a storm swings through sometime between the 30th and first 5 days of October.  ..We'll see how that plays out.. 

Regardless, i highly doubt that the overall weirdness we've seen across the country so far this year will take a break as the countdown to winter  '23-24 ramps up..  More on that later. 


 

[sandgroper]

Finished up a bit warmer than originally forecast yesterday reaching 29c. Much cooler today, heading for 21c. Mid next week they're forecasting 34c, a bit of a worry this early into spring, I'd like to see it remaining cool for a bit longer.

[flplantguy]

61.9 for the low this morning. I did not expect it to get that cool out but I'm thrilled. After the hottest summer recorded here I'm ready for fall.  Until now it's been short moments of upper 60s before it shoots up to 90.  Only a day then hot again but perfect for yard work.

[Xerarch]

No such cooldown for me, 79 as the low at my house this morning. I haven’t seen 60’s since before summer.

I've been hearing Sydney had a pretty significant heatwave not too long ago ..and of some brush fire issues already there 😬..   Aus. isn't  the only area in the S.H. dealing w/ abnormal heat in areas either..

And now 59.5 for a few minutes at dawn in central Florida in late September.  That's lower than I expected they said 68 but apparently its unpredictable here. The sand holds no heat so it's a bit chilly today to start but in Pinellas it's been above 70 all over. Even Hudson on the water is 69.  Makes me apprehensive for winter already.

[Silas_Sancona]

Seasonal Sunday in late September w/ a high in the upper 90's..

First week of " Astro "  Fall looking a little warm to start, followed by ..what could be...  ...if it holds, a pretty decent step down temperature wise right as October kicks off.  While not indicated on W.U's outlook, could we see a few upper 50s sneak into the lower deserts on the days where lower 60F lows are indicated currently??  Looks great regardless.




As for Monsoon 2023?? .......Close it up,  put it in a box, and send it packing..  the deal is sealed.. 

While final numbers, both locally, and across the state / region will take a touch longer to be finalized once the 30th has come and gone, one look at the current drought monitor across the state / west tells the story of just how abysmal this year has been in many areas of the southwest.. I honestly think the maps are a touch less accurate than they should be ..particularly here in S. Cen. / S. AZ, imo.  Considering the rain received from Hilary a few weeks ago, a little surprised far western / N.W 'rn AZ is under " Abnormally dry " conditions atm as well.  You'll see what i mean later..

All that said, it is good to see California almost completely free of -any- drought..  Remember this when the next dry cycle sets in..





In a strange irony, google evidently made a street mapping trip down HWY 83  south of Tucson back in August. Looking at views captured from various points of the route taken, ..and comparing them to how things looked while down there -around the same time-  both last year,  and in '21,  the effects of this year's failed rainy season,  even wayy down there,  are pretty eye openig..

Yea, there's a little green across the landscape, and in some areas close to the road, but, aside from getting a " eyes on the ground /  hands on " view of how everything looks during a really bad year,  i'm glad i was not able to make my usual trips south this year.. Wouldn't be much to see or collect seed from later.. Really,  years like this are when anyone interested in collecting a handful of seed from desired plants to trial should leave everything alone and hope that next year is better..


  At this point, we'll have to wait and see if winter beats back the above noted, increasing drought conditions.  More later.

Here in Pinal we have an excellent chance of sub 90 highs and sub 60 lows to kick off October. 

Really anything around 90/60 +/- is pretty nice. About time for the snowbirds to start migrating in for the cool season.
