Friday January 11 2019

As expected, the Winter Weather Advisory was issued for most of our area starting Saturday Evening. The Winter Storm Warning is for southern areas and begins Saturday morning in the mountains, but not until Saturday evening in St. Mary’s County Maryland. My initial snow totals are the same and now The National Weather Service has increased their snow amounts just a little to fill the upper end of my ranges. Compare the snow maps below.

Can this overachieve? That is the question I have been getting most lately. I have seen the NAM 3 Km shift the heavier snow north close to Rt 50 in MD as shown below. If we get more snow, then it will be with a shift north AND the Sunday Low getting better organized.

Winter Storm Warning

This includes: Charles, Calvert, and St. Mary’s Counties in Maryland. It gets a little complicated as the system is moving west to East. This Warning starts in the morning in the mountains. Then Charles Co begins at 4 PM. Calvert and St. Mary’s begins at 7 PM

Winter Weather Advisory

Carroll, Fredrick, Howard Co in Maryland and metro Washington begins at 4 PM

Baltimore east begins at 7 PM

Snow Total Forecast

The latest snow forecast from NAM  3 Km has shifted the heavier snow north. It now has Washington and Annapolis in the 6 inch potential.  If we get this storm to overachieve, it will be with a shift north and the Sunday Low getting better organized.

 

This is close to my first call map I showed this morning. I went higher in the mountains and Southern Maryland.

My Call For Snowfall

 

  • A: 6 to 8 inches in the mountains
  • B: 3 to 6 inches Southern VA to southern MD. This range is due to any mixing or rain early, but more snow later. Coastal Areas will get rain, but end with a burst of snow. I included them in this zone with the chance to catch up at the finish. 
  • C: 2 to 4 inches. Metro Washington, Annapolis, Baltimore, to York PA
  • D: Dusting to 2 inches. These areas will be on the northern edge and dry air form the arctic high needs to be considered eroding away what falls.

Snow Timeline Notes:

Saturday Afternoon:

Flurries or light snow. The onset between 2 and 4 PM west of the cities depends on how dry the air is. I see snow creeping in on radar, but it could be virga.

Saturday Evening:

Snowing in most areas around and after sunset. Maybe a few hours later in Southern PA.

Travel will be impacted and I expect many events will cancel. Snow will get heavier late evening and overnight.

Sunday Morning:

Most accumulation will be done central Maryland and north between sunrise and noon.

Some snow may linger later.

Southern Maryland will continue to get snow into the afternoon.

Sunday Night/Monday Morning

The only issue I see on roads will be late cleanup (some areas limit crews for cut down on overtime) and refreezing at night.

Here is a new product they posted this morning about their confidence and the impact.
