January 21 Bitter Cold And Winter Weather Advisory For Ocean City

Friday January 21 – Morning Report

This one is going to hurt!  The coldest air of the season is here and still might bottom out tonight. Baltimore has already reached 15ºF twice this month (4th and 16th). It could drop below that by Saturday morning. The record was -7ºF in 1984, so we can’t complain too much. 

In addition, the snow in Southern Maryland had a chance to stick, while the wet roads may have iced over in the deep freeze!

The spotlight remains near the coast, with a Winter Weather Advisory in extreme southeastern Maryland, including Ocean City for that coastal storm overnight. 

There will be a few clippers with hits of more light snow in the next week. 

Morning Surface Weather

The Low Pressure that caused the problems delaying our cold air yesterday had formed a little farther east. The lingering effect is what is going to cause the next system to stay southeast and barely clip coastal Maryland. 

More on the Winter Weather Advisory below…

Morning Temperatures 

Bittern Cold Reminders:

• Extra time to warm your car.
• Southern Maryland and Delmarva: Where it snowed and roads were wet, anything untreated will be icy. This includes local neighborhoods, sidewalks, and steps.

Here we can see the coastal storm jump off the Carolina Coast tonight, allowing the core of the arctic cold to fill in.

This will be followed by a weak clipper with flurries or snow showers Sunday evening. Then another arctic cold front with rain changing to snow on Tuesday. 

7 Day Forecast

We enter the weekend very cold, and a small system could bring light snow showers Sunday evening.

Most of the outlook is cold, with one mild day Tuesday. That will include a cold front that brings another round of rain ending as snow.
