Winter weather conditions per CTP this weekend in their morning discussion.
NEAR TERM /UNTIL 6 PM THIS EVENING/...
Broad closed upper low centered over Lake Huron early this morning and slowly lifting into eastern Ontario. Moist cyclonic flow over central PA maintaining widespread low clouds and fog with spotty light showers or drizzle. Very little change to sensible weather conditions seen for the daylight hours
but with the cooling temperatures aloft, precipitation will fall
mainly as snow showers across the higher terrain of the west
and north. A light coating of snow is possible at elevations AOA 2200 ft MSL.
Scattered to numerous showers are expected again today with sfc
heating and cold mid level temperatures again leading to diurnal destabilization. Some rumbles of thunder and a few lightning flashes are possible. Daytime highs should only max
out in the 40s which is 15 to 20 degrees below average in some cases.
