Yesterday we had sunshine with low humidity and a high of 70f/21.1c. 

Today was cloudy all day with much higher humidity. Today's high was 69.8f/21c with 57% humidity, however throughout most of the day it was slightly higher than that. Last night was on track to be fairy warm (still over 60f at midnight), however the thunderstorms rolled in and dropped the temps down to 14c with 90% humidity. Lots of thunder and lightning but not that much rain. 🌩️.

81F at 9:45AM on the 2nd day of May...

Chicken scratch says it all... Warm enough for good spring growth, but avoiding the " hot enough to start roasting stuff " kind of weather across the area..  ...For now at least..

Depending on how quickly the long, drawn out hangover from the SSW event back in March  fades away, " nice " heat (  ..and fairly benign weather pattern accompanying it  ) could hang on for another couple weeks,  before the first real taste of the summer ahead wanders into town..

Or maybe it sticks around a little longer, say into the start of June.. Don't think it will this year..

Regardless, At some point, soon enough,  Amplified pattern across the N. Pacific will finally settle down and retreat into the arctic, while the Subtropical High, currently trying to unpack it's bags  over Mexico will begin to exert it's influence.. 

For now, stuck somewhere between the two  ..which really isn't the worst place one could be.. :greenthumb:

Bad thunderstorm here on Wednesday night. I was awoken at 3am to what sounded like an atomic bomb going off. I thought the Ruskies had nuked us. My whole bedroom was illuminated by lightning. Several trees struck in my village too.

Another 15mm of rain from that event as well. I have already had about 75% of my annual total here and we have only just entered May. The past 7 months have just been so wet and cloudy with barely any sun or proper warmth.

 

More clouds and rain to come as well. The outlook is mediocre at best, for now. The transition to warm-summer Med (Csb) cannot come soon enough. It will probably kick in around mid-May, so within the next 2-3 weeks or so.

Northwest Scotland has been outperforming London and southern England in recent days. A few places are reporting 24-25C / 76F at 1pm there, whereas I am stuck at 13C here with overcast damp conditions. 🙄

Looks like another 90F+ day with humidity down in the 30s and 40s.  A little more comfortable for me, a lot less so for some of the palms from the wet tropics and subtropics.  Moderate rain chances for tomorrow have dropped, but a decent chance forecast for Saturday and Sunday.  We could sure use it.

@kinzyjr It looks like we get a few degree break courtesy of the Atlantic. Humidity has been low and I can see it in some of the palms. It is up to 75% the last couple days which is an improvement. I have misters turning on in my makeshift greenhouse a couple times per day to help.

May be just one model run comin' in hot ..on two different models,  but ...After a nice opening to May locally / Perhaps the last chilly storm for N. and Cen. CA ..inc. a late season gift for the Sierras over the weekend,

Things could flip, quite dramatically ( for CA esp. )   if this " Here right now, Gone in a day or so " blip on the morning forecast maps  turns into a trend over the next week.  Probably exaggerated but, ...ya' never know..  Obviously,  just some thoughts ....to be taken with a few chunks of Salt, for now.  Worth eye balling at least..

100-105F readings??  No biggie here, it's May after all.   Likely exaggerated,  but if it panned out, a sudden shift to upper 90s / low 100s would be quite a shock to the system out west where temps have stayed pretty mild so far into spring 2024.



Currently 84F at 9:44AM ..On the way to the mid -90s later, before a cool down arrives for the latter half of the weekend / start of next week across the low deserts of state 48.  Headed up north, or out west toward Nevada / far eastern deserts in Cali? get ready for lots of wind, and likely much dust.

*** GFS 12Z just about finished running = not as enthusiastic as the 06Z   ...For now..

A nice 87F at 11:14AM on your Saturday, on the way to the lower mid 90s later, before a dry cold front sweeps away the heat ...for a few days  ..before upper 90s return later.

As dry as it is now, plus some serious winds accompanying this cold front / trough as it passes through the area over the next 24 -32 hours, ..gonna be a bit of a nail biter as far as watching for fires across most of the state as well.


Screenshot2024-05-04at11-16-05ChandlerAZ10-DayWeatherForecastWeatherUnderground.png.505f431ccdb30a934ea6efce904efd8f.png


Will it get hotter just beyond the current 10 day???  ..continuing to watch.

After backing off yesterday mornings' bullishly hot longer term thoughts a bit, today's 12Z GFS wants to whip out the big boy torch around the 20th..  Fun to look at / chuckle about, but,  ...we'll see..  That said, both yesterday's 10 /14, and 3 week outlooks " see " the potential for  the development of a pretty hefty " western ridge / eastern trough " type pattern evolving soon.

Yesterdays ECMWF Weeklys product also appears to support turning up the heat in the west beyond this week..  ...so

Fun to look at what the 12Z is generating ( via Pivotal  WX, due to it's better resolution at regional level ), Even if just a wish cast / wish cast for now..


Screenshot2024-05-04at11-43-46ModelsGFS-PivotalWeather.png.736617681da967a673fc7e51a32dfe78.png



That said, ..if i were to put  -any-  weight into what the weather pattern could look like around mid month or beyond,  i'd  place a couple more pennies onto the scale when it comes to the idea of an early taste of Torch Fest occurring here over what the 12z is trying to suggest out in the E. Pac.

Yepp,  it's that wonderful time of year again when Tropical Ghosts start haunting the model runs again..  Where will this imagined entity wander to next?


Aletta,  ...is that you?   🙃


a3ef1b146910cff6f1a07b72e315dc27.gif


A bit of junk food irony regarding this year's hurricane season here in the E. Pac (  Which kicks off in about a week < May 15th > )

Last time this years list of names was used was back in 2018,  ala the six year rotation,  Bud brought us some early season showers in late June, ahead of what turned out to be a decent ( ..although not quite as wet as '21 )  Monsoon season.

2021 also saw a late June tropical wander bring us some showers right before that year's soaker of a monsoon set in

..2018 followed 2017's torch fest and dry ..but not as abysmal as last years'  Monsoon season..

2012 followed the 2 next most abysmal summers, '19 and '20.

🤔 

Scary stuff,  haha

A good example of microclimate or distance from an airport is on display in Florida today. The Brooksville airport is at 89 degrees right now with 38% humidity and at my house closer to the gulf it is 84 with 66% humidity with the seabreeze moving onshore. It was hotter before it started here too, it usually comes in by 1230 to 1pm and makes the afternoons pleasant.  For now.  Once the water heats up it doesnt matter so outdoor chores need finished asap here.  And the sun is getting brutal, some plants have been moved to shadier spots, or inside in one case, and i cant stand in it for more than a monent.  Rainy season can come as early as it wants just not the H word.

Despite the shoddy 2nd half of spring so far, it looks like we are about to enter British 'summertime' pretty much next weekend. I wouldn't be surprised to see London reach 25C / 77F next Sunday.

There is an evident drying theme as well, as expected ahead of a much drier summer period. I will be rushing to get everything planted out and ready ahead of this growing season. Mid-May onwards will be properly warm and dry, finally.

So far Scotland has seen the highest temperatures in the UK this year with 25-26C / 78F in some valleys of west Scotland on Friday.

That fire up in Scotland was pretty bad. I can’t believe western Scotland has had the warmest and driest weather so for this spring. Says a lot about all the wet/mild crap that we have endured in southeast England in recent months! It has felt like 7-8 months of autumn since October!

 

It has been way wetter than expected today as well. I have already racked up 15mm of rainfall since midnight here, although it looks like we are entering a drier, warmer period from tomorrow onwards. We better be seeing 25C / 77F somewhere on Saturday!

Temperatures have trended upwards a bit on the Met Office website as well. I think 25C / 77F is certainly nailed on for the weekend at least now in London. Potentially a bit higher even.

Take with a pinch of salt, but the Canadian model is showing 27C / 80F for Sunday. I certainly need to get everything planted out this week!

A high of 70f today and lots of sunshine the uv index was a 7.  

Not bad weather for early to mid May forecasted. Every day for the next two weeks will have a high over 20c.  Currently 16c/60.6f at 10pm. Apart from the lack of sunshine these temps are similar to May 2022. Sunday has the potential to reach 26-27c, depending on if it stays clear as there potential for cloud around 4-5pm which would mean a max of around 25-26c.Screenshot2024-05-07220259.thumb.png.925b5aedb55c3dabf99f9f3ad218dcd1.png

A decent for early May 88 at 5:37PM headed for a nice evening in the 70s, Bottoming out somewhere near 60 / lower 60s at dawn tomorrow..

Stubborn late season trough hung up over the Plains to our N.E. will continue to keep the heat across the S.W. in check thru the rest of the week / into the upcoming weekend  before it's influence starts to wane early next week, which will allow for a bump in 500mb heights, leading to temps. rising into the upper 90s / possibly right around 100F sometime in the Wed - Friday time frame next week.

At the same time, a chunk of energy expected to break off the main trough over the Midwest and retrograde back toward the Great Basin / 4 corners which may allow for some isolated shower/ T- storm activity up on the Rim / other areas of the High Country across the state / region thru the start of next week. 

Will also keep the " windy at times " pattern going up there adding to increasing fire concerns both up in the mountains, and lower down in the deserts where we've already had several brush fire events over the past couple weeks.


Still keep an eye on the more bullish thoughts on a big step up in temps. sometime around ...or just after... the 20th. 

Looking at today's thoughts from the GFS / ECMWF AI - FS / ECMWF Weeklys,  ..big heat is out there and the overall weather pattern across the west may transition to one where the building subtropical High across Mexico starts exerting more influence across the region, vs. remaining somewhat suppressed beneath continued late season westerly / slightly N.W.'rly flow off the N. Pacific. 

Since that " suggestion " has been waffling between various forecasts, we'll continue watching for see where it actually settles. 

That said, as the 18Z GFS shows below,  ..if the 4 Corners High does decide to flex it's muscle a little,  first round of big heat could be about a week / week and a half out.

CA may miss out on the first big flare up ..Suggested around the 19th by the 1Z GFS

For now, enjoy what may be the last round of " nicer " spring heat before fore-summer really settles in.

Temperatures are down slightly on this time yesterday. Currently 21.1C / 70F here at 12:30pm.

Quite misty this morning which suppressed daytime heating earlier, but that has now cleared and the skies are clear.

The Met Office’s UKV model is going for 27C / 80F on Sunday although that only shows up until 3pm. Presumably central London would reach 28C / 82F on that by 4pm.

@UK_Palms Microclimates in the garden make a big difference at this time of the year too. With the sun being pretty strong by UK standards. Whilst the weather station in the middle of the grass lawn recorded 23c, about 6ft away from the house, where there is also a large patio the temps reached 27c.  Meanwhile under the eucalyptus citriodora canopy and a mix of other plants it only reached 22c and the soil was slightly damp whilst the rest of the garden the soil is drier. 

Personally I think July/Aug's temps will depend on how dry it is from now to then, since for the last 2-3 years there were lots of reports and indications that 2024 had a good chance at having a hot summer for Western Europe. North Western Africa has been running above average so those 850hpa temps coming up from Africa will be warmer.

The met office updated todays forecast to 24c. It's warming up much faster today thanks to the clear skies.

Yesterday got much warmer than I was expecting here with a max of 25.1C / 77F on my main sensor in the garden and 24.9C on the one at the bottom of the garden near the open field.

Northwest Surrey was the warmest part of the UK for sure. Cooler temps on the nearby hills though around Guildford and close to the river, but still 21-22C / 70F in those spots.

We had a warm minimum of 18.1C this morning, by 7am it was up to 20C and going for a max of 25C with some late rain. That’s more of a summer scenario. Very warm for 2-3 weeks from winter.

Definitely warm for this time of year mate, 2 weeks from winter and we're still at 27c. Hopefully it's just starting and finishing a month later as it seems to do a bit these days.

Commonwealth Bureau of Meterorology:  rain with possible severe thunderstorms for Friday.

 

Me: Cheers, very grateful for the rain.

 

My backyard at 3.30pm with a beer in one hand and a hose in the other.  This is getting a bit grim.

Max of 26.8C yesterday here. Quite a few hotspots in the 25-26C range in southwest London and northern Surrey.

A cooler, wetter airmass will be moving in from Spain by Monday after temps peak on Sunday. Will somewhere reach 28C I wonder?

Overcast this morning but quite pleasant at the beach, heading for a top of 26c.

Weather is still summerly. Last weekend we got some rain which despite the wet winter was already necessary due to high to very high fire hazard in some areas. Lots of sun and warmth. Today's high was 28.9°C and the low 13.3°C. All of this continues but with increasing risk of thunderstorms. It's not clear how much influence an upcoming low pressure system from the Atlantic will take. ☀️🌴:greenthumb:

87 with a some haze due to smoke drifting down hill from control burns up in the mountains over night   Sunday underway across the valley..

Chicken scratch says it all   ..For now,  hangin in the " steady heat " range..   

Temps could bump up -a little- on and off thru the week ahead / next weekend ..but serious heat continues to be elusive,  for the moment..

Until we can get rid of the persistent post El Nino troughiness  that continues to keep the 4 corners high suppressed over Mexico, " Big " heat will stay focused over parts of Southern and E. Mex / far S. TX to our south east..

Things may finally start to change after next weekend, but, ..we'll see since the same " potential for a pattern shift " have been a " Here today,  Gone tomorrow " carrot dangling  in the longer term forecasts..


Screenshot2024-05-12at11-00-08ChandlerAZ10-DayWeatherForecastWeatherUnderground.png.f5b9b9f3dc0c07a81bb6634598ee0e66.png

That said, there has been some dry / high -based shower / isolated T- storm activity over N. and far E. AZ from moisture left behind some of the passing troughs ..and that may continue thru next week, with the potential that some moisture / outflow winds from any stronger activity that might form to our north or east might wander down into the valley sometime between Wednesday and next Sunday..

No rain for us, but, perhaps a tease of monsoon -esque mid level " debris " clouds drifting past on an afternoon or two.


..Other than that? ..We wait for the heat..




Quick look at what El Nino is / ..is no longer doing..



Today's CFSv 2 chart shows SST temps pretty much near neutral now, headed toward the beginnings of La.Nina.

Would like to have seen the index reach neutral about a month ago ( Green line ) with a steeper drop into La Nina territory but the decay of this El Nino has been dragging it's feet. 

How soon it decides to reach the " official " La Nina threshold ( -1.0C ) will determine what happens over the summer  ...and next winter ( Blue circled area ).  ( ..and perhaps next summer, lol )

For now..

As you can see on the OLR chart below,  Last El Nino - biased  Low pressure contor line is just about ready to fade away from the East and Central Pacific ..as the overall focus of Low pressure shifts back into ..and starts building over... the far W. Pac. / Indian Ocean..

While the High Pressure / La Nina bias contor < dotted lines > starts building in the Central / expanding east across the E. Pacific.

On the graph below, Orange colors represent westerly winds, indicative of Active MJO activity  while Blue represent easterly winds ..the In-Active MJO - biased phase. Stronger easterly winds over the Pacific = more upwelling of cold sub surface waters off N. S. America / scraping away of whatever warm water is lingering at the surface across the Equatorial E. Pacific.


Screenshot2024-05-12at10-54-33RealTimeHovmollers.png.177aba33196ec77ca6f958ee0ae24de9.png

Can see how, according to this model's current thoughts,  easterly wind activity starts to build across the Cen and Eastern Pacific, while the " El Nino favored "  westerly winds retrograde back into... and center up in the Indian Ocean over the forth-coming forecast period.

Essentially, the dawn of La Nina is just above the horizon.



Red Orange line = roughly the W. Pac / Indian Ocean.

Purple dot represents longitude at roughly Point Conception in CA

Green dot = roughly most of the Western and Central U.S.

Orange dot represents longitude a bit east of where Bermuda is located in the Atlantic.




See ya in 4-7 years, El Nino..

Thursday: Min of 55.4f/13 with a high of 76.1f/24.5c with 35% humidity. 

Friday: Min of 59f/15c with a high of 78.6f/25.8c with 42% humidity.

Saturday: Min of 55.6/13.1c with a high of 78.8f/26c with 43% humidity.

Sunday (today): Min of 57.2f/14c with a high of 82.2f/27.8c with 35% humidity.  Today was also pretty cloudy with it being a mix of clear skies and the sun shining through the cloud. If we had clear skies it likely would have reached 29c+. 

Saw the northern lights in London. I regret not taking a photo of the palms with the northern lights.

 

Not bad weather next week despite it being cooler. high 60s low 70s. 

Still 66.2f/19c at 11.45pm.

28.3C / 82F maximum here yesterday afternoon in my garden! By far the warmest day of the year.

The Met Office confirmed 27.5C as the maximum at Chertsey in Surrey, which is on the outskirts of southwest London and about 15 miles northeast of my location. A few stations came in at 27C including Heathrow and Kew Gardens obviously.


All change this week however, but still fairly warm/mild and somewhat dry. My last measurable rainfall was over a week ago now for me here. I could actually do with a little bit of rain already, which I am surprised to be saying after the past 6-7 months.

Some of my tomato and pepper plants have actually got sunburn too in recent days, so some cloudier and cooler weather is quite welcome. Overall not too bad of an outlook, especially given that I have just had 5 consecutive days over 25C here anyway, in the first half of May.

Also I will comment on the Aurora on Borealis on Friday night as I probably got the best photos in the whole of the UK potentially. I have uploaded them to Twitter where I have got 7,200+ likes and 1,100+ reposts.

I have tried to capture them maybe 10 times before in the past and never seen a thing here as I am a bit too far south and due to light pollution from Guildford and London, however the event was so extreme (strongest in decades) that I still got a fantastic showing on Friday night! Probably one of the best experiences of my life!

All photos are my own from my garden on Friday night.

Shaping up as an average May.

After upper 80's to lower 90's with clear skies so far this month, finally seeing a couple days in the upper 90's starting today. There's a chance for the first hundo of the year in my yard this weekend - got close one day in April but no, not yet!

All the snowbirds have left, as well as some of the 'fulltimers' who take a few months to travel during the summer. But it's really pretty nice still.

92F at 10:40AM  ..On the way to 98-101F later w/ a little haze and some clouds building over the Mountains / Rim north, east, and south of the Valley..

CODNEXLAB-GOES-East-subregional-Desert_SW-truecolor-1736Z-20240513_counties-usint-map_noBar-55-1n-10-100.thumb.gif.fd82d5ef5d02643fb7dd051639f23d17.gif

Buildups up there could lead to a few showers later, which in turn could send some breezes into the valley later ..as some high clouds try to sneak into the picture from the Southwest before Sunset..

Overall, forecast thoughts for the week ahead follow thoughts from the other day ..Pretty steady, with a few bumps up ..or down ..then up again..


That said ..12Z GFS back to some fanciful....
 
hauLee-carrot.gif

GFS 500mb Height potential around the 28th... 597mb is a pretty good heat dome for the end of May..  If it actually occurs..

Pivotal suggested temp map for the same time:

06Z  GFS hinting at a similar bump up in 500mb heights  -compared to the fairly tranquil Wx we've enjoyed so far this month-  soon too...

We know it's coming ....Arrival time may vary though, lol

The predicted thunderstorms haven't reached us yet. Up until today it was still sunny and warm. Tomorrow this might change but it's still unclear if and how the low pressure system breaks through. Had a high of 30.0°C and a low of 16.9°C. Night time lows are still very warm which has been a thing for months now. ☀️🌡️🥰

Got it today. 100 with humidity around 9% so okay, it's officially warm.

92F at 12:13PM, on the way to the mid 90s later w/ some clouds floating around / isolated showers / storms roaming parts of the Rim / far N.E. corner of AZ..

Storms up there could generate some weak outflow winds that reach the valley later.

 UPLL passing overhead might drag a couple high based drops / spotty light spit thru the valley as it starts moving east across state 48 overnight.

As it drifts over far E AZ / N.M thru the afternoon, same system could fire up some decent ..for Mid May... shower / storm activity in the high country to our north and east, which could bring a better chance of a gusty outflow into at least the east valley in the late afternoon/ near sunset timeframe tomorrow.. Per the latest thoughts from the local NWS.

Other than that?  Map below says it all for the weekend ahead / start of next week..  Not terribly hot, and not cold either..  Just cruisin' in the " hot  sweet spot "   for now.

Well i'll be    ..Our approaching Upper Level Low has a little more punch to it in the form of some High Based T- storm activity trying to get going to our south..  Some weak outflow winds attempting to move down into the valley from some storms up north atm as well..

We'll see what the evening brings ( Probably nothing 🙃 )


Something else  to keep an eye on for tomorrow too via the experimental Lightning Density product, 15Z HRRR from the U.of AZ WRF site:
