Mount Joy Snowman Posted March 28, 2022 Share Posted March 28, 2022 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.

Bubbler86 Posted March 28, 2022 Author Share Posted March 28, 2022 The trend I am seeing, for Wed AM, is lifting the threat a bit north of the LSV area AND delaying the onset but the CMC still looks fairly ominous with temps in the Mid 20's just north of the LSV (rush hour as the precip is moving in) Link to comment Share on other sites More sharing options...

TugHillMatt Posted March 28, 2022 Share Posted March 28, 2022 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?
