Southerly-tracking jet and a Genoa low = cold in Blighty. -

Winter 2022/23 - Moans, Ramps & Chat
Yarmy replied to cyclonic happiness's topic in Spring Weather Discussion
Dec 2010 was the 2nd coldest December in 350 years. Of course the current spell isn't comparable to that: it would be miraculous if it was. But this is certainly a notable Dec spell by any measure for the UK. Current CET is 2.0 which compares with Dec 95 and Dec 96. IMBY, it's colder than Dec 09 which was very cold and snowy (more so than Dec 10). -

Absolutely gorgeous day here. Hoar frost coated everything, bright sunshine and not a breath of wind. Beautiful: you’d have to have no soul not to appreciate it. Anyway, I can’t vouch for this guy, but Ant Masiello retweeted him, so… -

If you look closely, 3 members dip below -6 and off the scale, but only 2 return. -
Model Output Discussion. 3/12/2022. How cold will it get?

Model Output Discussion. 3/12/2022. How cold will it get?
Yarmy replied to chionomaniac's topic in Forecast Model Discussion
Yes, it’s the opposite of what you’d expect really with the GFS op stalling and disrupting the depression and the ECM op sending it barrelling through E/NE. It’s all so messy that I doubt this will get resolved tomorrow. -

Yarmy replied to chionomaniac's topic in Forecast Model Discussion
Not often you see those purple geopot heights so close to the UK: Reasonably high surface pressure and a slack-ish flow too, so you'd imagine that would be very cold overnight in the Highlands. -
Model Output Discussion - Deeper into Autumn
Yarmy replied to BlueHedgehog074's topic in Forecast Model Discussion
Yeah, it's interesting that despite a decade or more of upgrades, the GFS really hasn't improved all that much: -
Model Output Discussion - Deeper into Autumn
Yarmy replied to BlueHedgehog074's topic in Forecast Model Discussion
Sort of, but the whole Northern Hemisphere profile was more or less split in two. -

Yarmy replied to Seasonal Trim's topic in Spring Weather Discussion
Ironically, the Scandi HP that everyone craves is stalling the depression over the SE today. -

Winter 2022-23 early thoughts - general chat
Yarmy replied to Blessed Weather's topic in Spring Weather Discussion
That MetO contingency forecast identifies the 2 specific drivers being La Nina and the -IOD. But same time last year was also La Nina and -IOD (albeit weaker), so not sure why the forecast is different this time. FWIW, this is the one year I'd prefer a milder winter (for obvious reasons), so it would be typical if it ended up being colder. -
28C Marham at 11pm. What’s the criterion for the highest minimum in a day?

Temperature Record Monitor Thread
Yarmy replied to Radiating Dendrite's topic in Spring Weather Discussion
Yes, that’s why the official record is - whisper it - a bit meaningless. Add in the lack of homogeneity between stations too. Nonetheless, this is the hottest day in the UK probably for 1000s of years. So quite notable, lol. -

What’s remarkable is just how many stations are going to beat the old record. -

Temperature Record Monitor Thread
Yarmy replied to Radiating Dendrite's topic in Spring Weather Discussion
Leaving aside today’s madness, the nighttime record is going to get absolutely annihilated tonight. -
There was a thread a few years ago discussing what it would take for the UK to record a 40C temp. The consensus was that it would take a very unusual set of circumstances. Turns out all we had to do was wait.
