Wintry Weather All Week

The first of three weather systems likely to bring the mid Atlantic states wintry weather this week is impacting Maryland tonight.  Low pressure near Jacksonville, FL is forecast to move north/northeast overnight, while a part of the bitterly cold air over northern New England slips south and gets wedged east of the mountains.  The result will be a mix of snow, sleet, and freezing rain continuing into early Tuesday for areas north and west of Baltimore.  South and east of the city the precipitation may change to just rain as warmer air moves in on east winds off the ocean.  Our in-house computer model is indicating the bulk of the wintry precipitation should taper off between 6:00am and 9:00am on Tuesday, although some light rain or drizzle may linger into midday.

The second system to threaten the area with wintry weather this week will be a cold front forecast to arrive early Wednesday.  Temperatures ahead of the front will briefly warm up enough so that the front will bring a mix of rain and snow showers Wednesday morning, followed by breezy and colder weather Wednesday afternoon.

The third system is just now showing up over the Pacific Ocean.  This weather disturbance has a long way to travel before it reaches our area, but strong winds aloft will carry it across North America with an e.t.a. in Maryland of late Thursday night into Friday.  Early indications are that this storm has a chance to bring some accumulating snow to the region to wrap up a busy work week and it will likely help to pull some very cold air south out of Canada into the mid Atlantic.

Stay tuned!
