WEATHER BLOG: Cold On The Way
The Alberta Clipper tracking eastward across western Pennsylvania is weakening as a supporting upper level trough weakens and opens up so we are not expecting much in the way of precipitation in Baltimore.
It will pass by to the north this morning and swing its associated cold front across the region so only looking clouds and a passing flurry toward daybreak into Sunday morning.
Westerly winds behind the front will cause clouds to break for sun Sunday afternoon and temperatures will be seasonal so it’s a good time to get out and wash the car. It will be dry and seasonal across the region Sunday due to a west-southwest flow to the south of an approaching Arctic cold front.
The front will not reach the area until Monday night so Monday will be milder with westerly flow and clouds and some sun. The front will cross the area Monday night with little to no moisture available for precipitation but a wave of low pressure will develop along the Arctic front and track to the east across West Virginia and Virginia early Tuesday before moving out to sea Tuesday afternoon so there will be a chance of a bit of snow on Tuesday.
Bitter cold air will pour in from the north Tuesday night and Wednesday but it should stay dry.
