First snow squall warning of the day issued for areas just south of the border around the Catoctins.  Some interesting discussion from CTP.....

Concern remains for locally heavy snow showers/squalls this
afternoon. Marginal diurnal heating should promote transition
from bands to more cellular snow showers within a very steep
lapse rate environment. Higher March sun angle through cloud
broken cover should warm road surface temperatures above
freezing which could lead to an initial melting then flash
freeze scenario. However, very dry air near the sfc (mixed Td
dropping into the single digits +/- 0F) could limit ability for
snow to accumulate. Quick reductions in visibility are probable
in heavier snow bursts along with persistent wind gusts 25-35+
mph. The dry low levels have tempered confidence to some extent
regarding SNSQ risk/impact.

Today should mark the coldest day/night until next fall. Fcst
MaxTs are AOB record "mini maxes" with highs around 20F in the
northern tier to the 30-35F range in the lower Susquehanna
Valley - a remarkable 20 to 30 degrees below normal! (See
climate section of AFD for some daily record low maximums). The
cold NW flow finally loosens its grip on CPA Monday night as
ridge of high pressure begins to slide eastward from the Great
Lakes/Ohio Valley. Any lingering snow showers/flurries should
fade with clearing skies and decreasing winds into Tuesday. One
more cold night with MinTs in the teens to around 20F or 10-15
degrees below normal.

3 days in a row of (temp) accumulating snow for some on this forum.

So sorry to read about this bad accident. I wonder why PA seems to have more issues with these bad accidents in squalls. We get our fair share of them here in NY, but these accidents seem less common. Maybe because we expect them more often here and are prepared a bit more?

I would guess that many of the people on 80/81 in the area of the majority of issues are not locals.
