55F, foggy / drippy and still raining w/ more lining up on the radar for overnight and possibly into tomorrow morning.  It's like being back in San Jose, haha..



Considering the forecast just 24 hours ago, pretty impressed by how much this storm has over performed.. up to .63" here as of 6PM, w/ lots of .50" - .70" / .70"+ totals to the east / south.  Could easily surpass the earlier suggested .79" rainfall total by tomorrow AM here if heavier showers now approaching Yuma keep rolling our way for the next several hours.



Tucson was supposed to be the bullseye today, but watching the radar on and off thru the day, most of the heavier rain has stayed north of town.

So yeah, after the overnight rain we are at over 3" for the 24 hour period here in Pinal county...  about 4x the expected amount.

Yep, wayy more both down your way, and up here than forecast..  Thursday night, most forecasts were saying this side of town might get .25"- maybe close to 1/2th of an inch. Higher potential totals were confined to just south of Casa Grande, thru Tucson..

Both areas got what was suggested, and then some ( Pinal County esp. ) Rain finally redeveloped over Tucson late last night.  Just starting to end down there atm.

Rainfall totals, As of 5AM via Tucson NWS Can see where the bull's eye was this time.



Maricopa County Flood Control District Gauge totals ..The crude map, lol,  Not the nice one ( Won't let me take / save screen shots )

Looks like 1.10" will be the grand total for this event here in Chandler.. Impressive enough..  More impressed w/ the totals just to the south east of the 202 in Chandler Heights, S. Gilbert, and Queen Creek / San Tan.



Believe it or not but yesterday's rainfall also ended up setting a daily record at Sky Harbor..  Notice the other, previous records were set in August, September, or October.. That said, still well below normal for the year.  Hard to see but the old daily record of .69" was set back in ....1908.



61F humid, and cloudy atm.. May top 65F if clouds can break up thru the rest of the day..

Daily WeatherDoge update - wow such whatever

 

Love that y'all love an app based on an ancient meme lol 

[UK_Palms]

We have a big freeze on the way. It is literally the worst case scenario possible relevant to how it has set up and how cold it will be getting so early on. Up until now this has been the warmest year on record and we have just had the mildest November on record too. However the strong Greenland blocking, which is almost record breaking, is pumping down arctic air deep into western Europe. This is exactly the worst possible scenario going into winter. Hopefully it doesn't last too long.

 

The last time this happened was during the infamous 2010 freeze, however this time round the sea temperatures are warmer & 850 hPa temps aren't quite as cold either. Still it will be my worst freeze since January 2021 at least and probably my 2nd worst freeze in the past 4-5 years since at least the Feb 2018 event. Potentially my 3rd worst freeze since 2010.

 

Met Office temps for my nearest station, Farnborough, look disgusting but that is 10 miles away in a frost pocket area that usually gets 1-2C / 2-4F colder than my location. There are microclimates dotted around in the Surrey hills that may or may not influence nighttime minima in my favour depending on the type of cold, pressure, winds etc.

 

It's looking cold in the warmer parts of London as well by the Thames. Potentially 5 consecutive nights of frost but an ultimate low of only about -1C / 30F. Make of that what you will. 

 

I have lifted the Ensete Maurelii as well today. Not letting that get zapped later this week. It did well to stay outside this long unprotected at 51N in the rural countryside, 35 miles inland from the coast. Last year I brought it in 4-5 weeks earlier. I thought about building a shelter around it and packing it with insulation, but not worth the risk. I think I will get -6C / 20F here at least on one of the nights.

 

I don't know whether to bother wrapping the bananas or not. I don't want to lose them though, especially the younger clumps... @Chester B

 

The various Phoenix and Washingtonia dotted around my property are going to have to fend for themselves during this event. It's weird seeing so many plants flowering still, despite the fact that a fairly big freeze is now imminent... 

 

The chillies/peppers are still clinging on here for now with no protection, but this will be mush within 5-7 days.

[Silas_Sancona]

59-61F around town at 11:06PM under humid and foggy skies.. Anticipating more sun after what could be a very foggy start, and a high of 68-71F tomorrow..

Some adtl. rainfall totals from earlier: The 1.10" i thought we clocked for the storm? ..add another .42" to that, for a grand total of 1.51" here in Chandler.  Downtown Phoenix reached 1.17", which is the highest rainfall total since Feb. 21-22, 2019.  Just south of town, Arizona City, a tiny town just west of Eloy and I-10, experienced fairly significant flash flooding earlier today.



Rain that redeveloped late last night continued on into later into the day down in Tucson, helping them end up w/ some reasonably healthy totals. 



Select totals state-wide, and across the western half of New Mexico, where many areas also saw some decent totals from this event.. Can also see areas near Puerto Penasco, near the Gulf of CA.  S.W. of Tucson, also saw decent rain.  Impressive since that area sits on the edge of the driest portion of the Sonoran Desert / overall southwest, aside from Death Valley.



By far the winner for this event, overall?  M. Lemmon down near Tucson, w/ a whopping 6.30"

It's currently 39f/4c in London. This is the coldest temperature so far this winter and it's feeling pretty chilly. Yesterday got up to 8c/46.4f and was clear skies all day. Here's also an update on the Kew robustas.

[Ryland]

It’s currently -0.7°C making this the first frost of the winter and by far the coldest temperature since January. Expecting a run of very cold days now with every night below freezing for a week, days just above freezing. Temperatures as low as -3°C expected. It will be the coldest week since February 2018.

I escaped a frost here last night with a minimum of 2.9C / 38F. That won’t be the case tonight though with my first frost in 7-8 months arriving. It is so cold here today. Only 4.1C / 40F at lunchtime. Bet I get something like -5C / 23F tonight under clear skies and the the arctic airmass. This air was literally sitting in the arctic circle a few days ago, before getting pumped down our way. We best brace ourselves. It’s going to be the worst freeze in 5 years since the Feb 2018 event. Record low minima for the dates in my neck of the woods over next few nights.

Mid to upper 50s around town atm as some clouds roll through. Anticipating a high of 64F later..  Rest f the week / weekend look nice, in the 60s in the 60s, before a stretch of chilly stuff settles in for next week.. 

Appears frost threats are on the table as well. No worries / need for non necessary panic, it is winter after all and Arizona Ain't the Amazon  ..Frosty stuff happens in the dead of winter here..

If the " feels like " pattern follows what the PNA appears to be suggesting, if it doesn't change direction of course, perhaps a warm-er ish trend emerges sometime around / after X-mas / to open 2023. < Somewhat opposite of last year >








NAO looks to start thinking positively again too..




Checking a couple random W.U. stations, looks like conditions are similar back home in San Jo'. ..and down in Vista, though their forecast suggests they stay slightly warmer ..Both areas look to get more beneficial rainfall.

Cannot ask for better....bring on the steady southeast flow!! 😍

[UK_Palms]

The temperature is absolutely tanking here under the clear skies. I haven't had a freeze up until now, but already down to -4.1C / 24F at 2am here. Probably going to bottom out at about -6C / 20F come dawn. Likely a date record for my area, although I am expecting worse to come tomorrow night. I haven't had anything this cold, this early on, since December 2010. Even back then I think the proper cold was quite a bit later on in the month too, so this freeze is particularly extreme. Worse to come tomorrow night. Sigh.

 

The GFS ensembles suggest temperatures will recover properly around mid-month, although there is a lot of scatter. The red line indicates the long-term mean, or what it should normally be at this time of year. As you can see the airmass we are now under is 5-7C below average for the time of year as it has been pushed down from the arctic.

[GottmitAlex]

Wowzers! 

[Ryland]

Currently sitting at the low of -2.4°C, which looks very frosty due to the high humidity. Most of the central urban parts of Manchester are about the same, outer parts including the airport (nearest official Met Office readings) are around -6°C. So far that hasn’t broken last winter’s minimum of -2.7°C, but we’ve got another week of the same so I expect we’ll get below that at some point. It looks unlikely to be severe though, probably no colder than -4 or -5.

[Tyrone]

It got a humid 27C in Albany today. Warmer than expected. 

[UK_Palms]

New daily record low minima set for multiple sites in my area. The ultimate low for me was -6.1C / 21F. I have never experienced a temperature this low, this early on in winter before. Even London City airport by the Thames went down to -1C / 30F last night! Here is the nighttime minima anomaly map (not actual temps) for last night. Many places 8-10C / 15-20F below average, including where I am…

Daytime recovery is not going too well either. I was just driving through Charlottesville and the hills are still white with frost at 1pm. Despite the clear sunny skies (quite pleasant in the sunshine) it is still only 3.4C / 39F here at 2pm. I doubt I will get over 4C / 40F before the sun starts setting around 3:30pm.

Another harsh radiation frost will follow tonight, like last night, only even colder this time. There is no wind whatsoever, not a single cloud in the sky and -9C isotherms moving in now from the arctic. Literally the worst possible scenario for cold where we are. Like you couldn’t have a more perfect setup for it. Disgusting!

@UK_Palms it got to -0.8c, I was around 0.2c warmer than surrounding weather stations so Im guessing my pond, mulching and patios here have kept it slightly warmer here but I have a feeling tonight will be slightly colder. The warmest parts of London had a low of 33f in the city of London, surprising the covent garden wunderground stations was only 0.1c warmer than here though. So far archontophoenix cunninghamiana and the potted Alexandrae look undamaged. The website you posted a photo of shows -2.2c for Scillys st Mary's but the wunderground stations there haven't gone below 42.4f/5.7c. The high today was 43f/6.1c. The only positive thing I can say about this is this is as bad of a setup as 2010 but it's significantly warmer. Dypsis rivularis, or whatever the new name is, seems more hardy than I was expecting. It only has some sunburn damage from that 40c day no frost damage.

Another summer day in December, now 85F at 3pm after hitting 87F just past noon. Things are growing and blooming like its the second coming of summer 

[Foxpalms]

Around 3am it might turn cloudy, this is significant and may reduce any damage here. Escpially for those living in colder parts of London.  Hopefully it stays above 30f for as long as possible here. Currently 34.

[UK_Palms]

@Foxpalms I actually think this is a worse setup than 2010. The polar vortex was totally disrupted about a week ago, shifting all that polar air southwards into a vacuum that has deposited it directly over the UK. We have had a northeasterly airflow/wind for about a week now with Atlantic totally cut off (no rain so far this month). The polar air has only just arrived.

Combined with near record high pressure over Greenland and extreme heights over Scandinavia, it means that arctic air is just channeled/pumped down to us and it also means clear skies and pretty much no wind allowing for unprecedented cold for the time of year. I'm hit especially hard out here in the countryside. Look at my 10:30pm temps...

The record low for 8th December in my region is -5C / 23F back in 2010, so that is pretty much gone already tonight here and will only get lower... 

 

Benson is a notorious cold spot in south central England, which is located in a frost hollow near Oxford. The date record for the 8th December there is -6.6C / 20F, which was set during the infamous 2010 freeze. However as of the time of writing this, Benson is already down to -9.4C / 15F there. The record has already been smashed with another 8-9 hours of radiational cooling left to go. Their minima date record could potentially get broken by 5-6C / 10F come dawn, depending on any cloud cover. So this is a bad, unprecedented freeze.

It is a similar story in many other places. It would be even worse if the sea temperatures weren't so much above average, since they have mitigated some of the Arctic air mass. It also speaks volumes if central London isn't really going below 0C / 32F during such an extreme setup. You won't even see any damage on the CIDP or Washingtonia in the protected parts of London from that, even if we get a week of this Arctic crap pretty much. It just doesn't get cold enough there, unlike in my location. The daytime recovery is just about sufficient, but not great still. Hopefully it all ends later next week.

 

@Xenon So envious of your weather right now. Meanwhile my bananas and Queens are all wrapped up. Tarpaulin draped over the Chamadorea, CIDP and Washingtonia's. The Filifera is being left to slug it out unprotected though. My garage is jam packed with various exotics that I'm not taking any chances on. I should have just relocated down to the coast this year where I wouldn't have to go to this fuss protecting stuff. I'm too far inland with no UHI here. Every 4-5 years I get hit fairly hard. 

[Arecaceus]

Currently 4°C at 1:22 AM. The forecast predicted -1°C for this time. Glad it's not -1°C. Official weather station says 3°C.

[Foxpalms]

@UK_PalmsIt is currently 32f at 1.35am here.  The warmest parts of London are at 34f currently if this is one of the worst cold setups and this is the temperature, king palms are definitely long term here. The outskirts though look very cold. What's annoying is just the prolonged cold weather for a week or so.

Update. It is so mild in central London compared to the rest of the south east. Its warmer in central London currently than it is anywhere on the south coast except the extreme south west. Even the Ventnors wunderground stations are colder currently tonight. The only places warmer is the peninsula near Margate,  Anglesey, the channel islands, far costal south west Cornwall and the isles of scilly. If this is possibly the worst cold setup in a very long time and it stays above 30f I'm definitely planting out the more frost tender archontophoenix palms next year. Since its a dry freeze I don't see any frost on my archontophoenix cunninghamiana yet.  @UK_Palms It looks very cold where you are hopefully the queen palms pull through the freeze.  It looks like there's even be snow clouds in Cornwall, but I doubt any will stick. The isles of scilly still haven't gone below 40f.

What is keeping central London so mild in this setup? The USA has some megacites that show a clear heat island effect but not to that extent.  I also don't get how if only reaching 3-4C at warmest time of the day it's not dropping to -10C or so during the long nights in Dec at that latitude.  Down here in mid winter can easily drop to -3C overnight purely from radiation cooling after being 11-12C the preceding afternoon and the night will be 1hr or more shorter.

Nice work with all the covers. Summer has its challenges but winter sucks as a zone pusher, I'm glad when each one is over.  What you are going though will be us again in 6-8 months time. Of course most of us just could select species with a zone or two of safety margin and have a worry free winter with no work, but where is the satisfaction in that? Pushing the boundaries is what makes life interesting, it means covering and moving stuff undercover at times,  also sometimes things get damaged or lost despite best efforts, it just comes with the territory.
