All Activity

There was widespread 10s in the northern plains. My point though is that everyone got a piece of this. Maybe we linger some slightly BN temps into the weekend with chilly mins, but we’ll still have some napey 60° afternoons.

Yeah, I was 91.2 a few days ago and last night 23.9.

Impressive airmass and even more so after a week of 80-90 degrees

Thanks Colonel Kurtz from a philly board for these stats, impressive! Both obviously record lows. 27 degrees at TTN is the coldest this late in the season on record, previous latest 27 degrees was 4/20/1926, AVE date of the last 27 degree day is 3/25 24 degrees at ABE is also the coldest this late in the season on record, previous latest 24 degrees was 4/16/1943, AVE date of the last 24 degree day is 3/26

Low of 24, was below freezing from 10:45pm to 8:10am, a solid hard freeze, pun intended.

….Certainly slowed everything right down that’s for sure.

A brisk 22.8 this morning

31 this morning. horrific stretch of weather coming up. Close the shades until Memorial Day

Nice firebox.

Not so warm after all. Climate being climate is all.

Summer!

Shocker, 00z Euro moved precip maximums to PA. We get some, but nothing sustained it seems.

That's frost. Open fields and car tops typically begin frosting at 36, particularly on nights with high radiative proficiency.

Got down to 29 last night. Fingers crossed this is the last time we hit the 20s until the fall

No frost here on the shoreline the last 2 nights. BDRs low was 35 yesterday and 33 this morning.

Just stop. Lol

Not as long; not as deep - or will be. So it appears

It seems about hours 72 to 96 removes the -NAO ridging in the ensemble means... but, maintains the behavior of the flow across the eastern mid latitude continent - as though it is still there. The models are "sensing" some non-linear mechanics for -NAO, powerful enough to shape the linear ( observable wave distribution ) handling whether the block is there or not. One consequence, the Euro and CMC 00z solutions. Hopefully they are wrong. Because they're attempting the dreaded rock-bottom pattern lock in using that. Particularly the CMC .. long about 156 hrs it takes tiny meso-beta scaled S/W and uses it to carve out a 3 contoured close low and when you loop it almost seems like a spontaneous manifestation with no real input. Black hole just opens up in the perfect position to impose fantastic torture. Hyperbole aside, that's that non-linearity being exposed. But it doesn't have to be right because it's beyond 120 hours. Otherwise, move to 2nd residence and don't come back until some time deep into May

Got down to 28 here. Die mosquitos, die!

To be fair this airmass affected most of the rest of the country too.

Hard freezes in a warming world

It's fallen right back into that "targeted" cold anomaly that festered the entire winter ... enabling straw men deniers two sheets away from being as smart as flat Earthers.

29 low here

I thought the BOS record of 21° for today was a joke until I saw 16° at CON. What the hell was that airmass in 1875.
