We are starting to see the warmer air filtering in and cooling as it connects with the snow-covered ground. The problem that will create is a bit of fog and visibility concerns.
Temperatures in Baltimore are at or above freezing right now, but it is 30 in Frederick and 30 in Westminster. Areas west and north of the city will still have some freezing rain and freezing drizzle through about 9 a.m. With the fresh snow on the ground, temperatures will be even slower to warm. Those areas will struggle to get to the middle 30s. It will hit around 40 in Baltimore, but that can be a struggle as well. Rain will taper off to drizzle by Monday afternoon and end by sunset.
Snowfall amounts along the Mason-Dixon line were mainly 4-8 inches.
There will be some icy spots west and north of Baltimore. Snow can mix with sleet and freezing rain Tuesday with 2-4″ of snow/sleet possible. Tuesday is starting to look quite interesting, especially with the models trending farther north with the track of the next wave that will develop over the Carolinas Monday night and quickly move northeast off the East Coast Tuesday.
At this point, temperature forecasts vary by model. The GFS (the coldest) is supporting all snow. Either way, there can be sleet and freezing rain for a time before it all ends as snow. At this point our thought is for 2-4″ of snow and sleet. If the NAM model is right, we could see closer to 2″. If the GFS model is right, it’s closer to 4″.
We will continue to fine tune the forecast with further updates through the day Monday.
