FIRST CALL for Monday's major winter storm

12:13PM 1/3/25 - Here’s what you have all been waiting for. Our first call on Mondays snow storm.
First off, this will be a high impact event regardless of just how much we get. Roads will be snow covered and very dangerous to travel on. We expect widespread closures not just on Monday, but potentially into Tuesday as well.

Precipitation type is still a little uncertain south of I-70. North of I-70, we should stay all snow. Between I-70 and Route 50, it should be mainly snow, but a mix is likely at times. South of Route 50, a mix is likely and some freezing rain is possible as well.
​
The exact track of the storm is also still a little uncertain which is to be expected 3 days out. A track further north would lead to more snow in northern MD, while a track further south would lead to more snow in central MD. Either way, significant snow is likely in our area.

As far as timing goes, snow should start from SW-NE between midnight and 3am for our SW zones (DC metro), and after 3am for our NE zones (Baltimore metro). Snow will continue all day Monday before tapering off Monday evening. We expect a winter storm watch to be issued for the entire area later tonight.

In total, we expect a widespread 3-6” for areas along and south of a line from Sterling to Laurel to Annapolis, as well as north of a line from Gettysburg to Shrewsbury. In between, across much of central and northern MD, 4-8” is expected. This may be a bit conservative, and an increase is possible. If there were to be any changes to this forecast, it would likely be the placement of the 4-8+” zone. It could shift either north or south. ​
