I'm trying to wrap my head around being at 32 - 34 in Hagerstown while Cumberland & Keyser WV is at almost 60 hahah.

Low was 19 degrees. Currently 29 degrees. I was supposed to smoke some Pork Butts Friday. Looks like that might get put on hold. 40 mph winds is a no go.

There was definitely a trace of snow that fell in the Hickory area/Catawba County on November 10th, December 8th, and December 12th. There were multiple reports on social media of people seeing snow on those dates.

They'll end up getting a 4'er in April.

New York City's UHI has been around for decades. The numbers are warmer there, but the differences between cooler or warmer outcomes relative to climatology apply. Having said that, there are day-to-day issues at the Park. Actually, Central Park's December lows relative to those at White Plains have changed very little. Of course, when conditions are ripe for radiational cooling, there will be large temperature differences between Central Park and White Plains.

What do we consider “flash”? Temps will drop midday on, but I doubt most hit freezing until evening. I’d personally call that regular CAA. It’s not like we’re refreezing slush either.

Boulder, more like Smolder

Not backing off much at all really. The difference between a -3 to -4 from 2 to -3 in a long range forecast is pretty much statistical noise. The EPS is around a 0 to +1 the rest of the month. So that would yield a 7 station average of around -3 to -4 from the current -7.7. Long Island is running a little warmer and is only -5.5 at ISP through the 16th.

Euro - within the last few days was also suggesting something similar but that negative NAO and the strength of it and the HP position in southeast Canada along with the warmer air trying to attack it could set up a gradient/overunning event somewhere in the Northeast and or Mid- Atlantic - example it might be in the 50's in Richmond and closer to 32 in NYC - we don't know yet

Riveting

Flash freeze late Friday?

Thank God

Yeah figured I'd bring that up since it was too positive around here. If we are to believe the machines

Bottomed out at 23 last night. .

Torched to 43 yesterday. Lost 2” of snowdepth, now 7” at MSP.

I think a half inch or so is possible.. I guess we'll see

I mean if we keep shutting down climate studies, closing facilities (NCAR) and "burning" climate data, it obviously means it isn't real.....It happens all the time is the new response and will be backed up by the "new" data, complete with black sharpies that of course shows "it's all normal" But back to current discussion, hope it snows some time around Christmas, otherwise let it warm up so kids can play outside and travel isn't disrupted

I don't think we see anything white out of Friday's event... maybe a few soggy flakes... but no accumulation

Your skinny ass does not have enough meat.

I did a statistic analysis once that had a 0.25 correlation to the pattern after 2007, a 0.30 correlation to the pattern after 2013, and a 0.40 correlation to the pattern 2019-2023. It dropped a little bit since 2023, but is still in the ~0.35 correlation range. Historically, the correlation as not as high but still there (0.05 to 0.10 before 2007)

GFS is interesting for christmas eve and especially Christmas day!

Thanks, do we have statistics on how much the frequency has increased since 2007? Was there another "spike" in the past (if it was even tracked)?

Happened a few times here last year.. elevation FTW

And no real cold following that... sometimes they get those rapid drops

When I was walking out to the car this morning a massive owl flew overhead. Took me a second to realize what it was...thought it was a pterodactyl at first and was about to dive in a bush
