19.4° at 8:30. Forecast is 12°. I suppose it’s possible but I have a suspicion that it levels out around 14/15 for the low.

I was wrong - low was 11.8°. Currently 14.4°

[rickymdwx]

low of 12.4

[Eskimo Joe]

Low of 10.1°. This is the third coldest morning I've experienced since moving back to Maryland in August of 2016. The record was 2° on Christmas Eve morning in 2022 after the big frontal passage.

[ThePhotoGuy]

Low of 18.3. I guess the Patapsco River kept the area warmer last night.

I checked some nearby stations to mine and they were all in the 18 degree range. 

[clskinsfan]

Down to 10 this morning. Cold. Period. 

[WxUSAF]

GFS was way too warm this morning. Euro even was too high, although closer than GFS. NAM from yesterday also too warm surprisingly. GGEM was too cold of course.

[clskinsfan]

Wild seeing the creek near my house starting to freeze up. Honestly cant remember it happening that quickly in a long time. 

[North Balti Zen]

I think a low of 10 for my backyard this AM.

18z HRDPS from yesterday was right on the money - it showed single digits in the northern areas with that warm pocket in southern MD. IMBY-wise it was the only model showing 12° and sure enough that was the low.

This is all going in my weenie folder for later when it’s the only model showing us getting snow.

Something seems up.

WWA is up

Departing.  Mongolia air masses are different.  This high is not moving off mid Atlantic, more like off Boston . This isn’t a 1994 set up which gave us freezing with no snow at 22F.  Look for a surprise when the precip starts

The biggest “problem” is that there just isn’t much precip with this.  Meso models are in the few hundredths range.  If we were looking at a big shield of precip coming in I’d agree with you.  But it is very likely just some pingers and/or light ZR for a bit.

Not much yet and I believe that will be under estimated .  We are already way further into possible wintry than  was thought 48 hours ago
