Winter weather advisory in effect; Storm could impact holiday travel

BALTIMORE —Winter weather advisories have been issued for parts of central Maryland as a large storm over the Midwest is set to come across the Gulf of Mexico, grab some moisture and ride up the East Coast starting Tuesday into Wednesday.

For Tuesday, federal agencies in the Washington, D.C., area are open and employees have the option for unscheduled leave or unscheduled telework.

A winter weather advisory was issued by the National Weather Service for northern Baltimore, Carroll, Frederick, Garrett, Allegany, Howard, Montgomery, Prince George's and Washington counties from 6 a.m. to 4 p.m. Tuesday. The storm could potentially impact holiday travel.

The NWS said precipitation will start as a brief period of snow and sleet early Tuesday morning, then likely change to freezing rain by mid-morning Tuesday and continue as freezing rain during the afternoon.

11 Insta-Weather PLUS Chief Meteorologist Tom Tasselmyer said Monday evening that we can expect to see all varieties of precipitation in the region, including flurries or snow showers in the morning with heavy rainfall is possible in the Baltimore area later in the day.

"It's primarily a rainmaker for us, but the beginning and the end of it could be a little bit wintry," Tasselmyer said.

He said snow, sleet and freezing rain are possible until about lunch time followed by steady rain into the evening. As the cold returns, the rain could return to snow Wednesday afternoon followed by sunshine on Thanksgiving Day.

The wintry mix could produce slippery conditions on roadways, so drivers are being urged to take care and leave early if needed.

A cold front over the upper midwest will combine with the storm moving from the Gulf of Mexico, and when it tracks inland, it produces more rain than it would wintry weather.

The average high temperature for this time is 50 degrees, but on Sunday it only hit 32 degrees. Those going to the Baltimore Ravens game on Thanksgiving night can expect temperatures to drop into the 20s.

Meanwhile, forecasters in western Pennsylvania are predicting as much as 6 inches of snow in some areas.
