January 19 2019

A Winter Weather Advisory is in place for our Northern Counties and that is exactly where snow and sleet burst open this evening. I have been watching temperatures and there has been a drop of a degree or two with the burst. But even where temperatures are still above freezing, I had mentioned that it was possible to get stickage. The snow and sleet can cool the ground to support that. This led to many slick roads and accidents.  The photo from Ryan Seymour in Emmitsburg was showing stickage at 37ºF. We have a few hour of some slick travel, but the warmer air will eventually win.

 

Here is a quick look at the latest conditions and short term forecast this evening. You will see the warmer air will eventually take over.

Temperatures

Stations reporting at or below freezing have been circled.

North central Maryland

South central Pennsylvania

The winds have been added, shoeing the flow from east to west.

 

Droppler Radar

Snow and sleet have been highlighted as of 6:30 PM.  I added in the winds to show the flow from the east. This comes from the Atlantic and will warm up the atmosphere within a few hours.

Temperatures

The warmer air will be moving in before midnight. We should see Baltimore rising to near 40ºF, while Harrisburg may hang on the freezing.

 

Sunday Morning

Baltimore may be in the lower 50s at sunrise.

Northern suburbs should be in the 40s… but not for long. The cold air will be on the move and reach these areas during the morning.

 

Sunday Mid Day

  • The NAM has us dry when the colder air arrives.
  • The Freezing line is expected to cross Baltimore and Washington between noon and 1 PM

 

 

Temperature Drop = Flash Freeze

Anything still wet can freeze within an hour. That means wet pavement can get icy very fast.
