With this 1040 high sliding over us and if winds can slack it will get real cold

That would do it. Get the wind to slacken with clear skies and might get close to zero. Wind likely wont completely die down though so probably 6-8 for a low here.

Would not be surprised if it gets a bit lower here.  18/1 now and the DP keeps dropping.  Didn't get above 20 here also today and the 20 we did have occurred at 2pm before temps started dropping again.  Nice and crisp outside now.  Combination of limited snow cover (here it's limited - others got far more) and frozen ground has that nice crunch sound to it.  Will be interesting if there's some school delays in the AM just due to just the cold...

NWS seems to claim Salisbury hit 0 this morning...Big outlier for the LWX area

ETA:   Huh...checking around the shore....Millville at minus 4 ....-4f

Totally believable given there is over 10" of snow in those areas, clear skies, almost no wind.

lol how can this be such a mystery?


It shouldn't be a mystery that snowcover will lead to colder nighttime temps, but that's some pretty cold stuff. It's incredibly rare to get below zero in many of the places that got there last night.

Parents' house in farm country of South Jersey radiates like a mofo. They have about 6" on the ground and they hit -1F. They do go below zero given the right conditions to radiate well, so this is totally believable, but some of the readings around this region are really impressive.

Places on the Delmarva can radiate very well, not quite as well as the Pine Barrens. Salisbury area has a very sandy soil, and is often colder than my area with no snow cover when a cold, dry air mass is in place with HP overhead.

Makes sense that the Eastern Shore might radiate well, but that's interesting about the soil component.

Here's what I've found in SE VA and NE NC so far:

KRIC: 0

KPTB (Petersburg/Dinwiddie VA): -8F

KLKU (Louisa, VA): 3F

KPVG (Chesapeake): 9F

KSFQ (Suffolk, VA): 3F

KFKN (Franklin, VA): -2F

KEMV (Emporia, VA): -6F

KECG (Elizabeth City, NC): 11F

KPVG (Greenville, NC): 3F (this was actually late yesterday)

KIXA (Roanoke Rapids, NC): 5F

Anyone seen any below 0 temps in NC?

 

Back home in Staunton KSHD got to -1F, but that's pretty common at least once a year.  CHO and EZF hit 7F, which is pretty cold for them.

You see the same thing on Long Island way out on the east end.  The temp dropped 18F (from +9F to -9F) in 2 hrs this AM once the winds died.  Same soil composition.
