The National Weather Service has issued their Alerts for the snowstorm on Monday. In this report I included the latest HRRR Model in slider form. This will be easier to control and see the timeline at your discretion.
There are a few things I think should be addressed with the storm that is important beyond just the totals:
I will address these in maps below.
My goal is to get into the storm dynamics in my report tonight.
This is following the logic I discussed in my earlier reports:
A sharp cutoff on the northern edge. Southern PA is not included, but still may get snow for a few hours.
Winter Storm Warning: NWS is calling 3 to 7 inches of snow. EXPIRES BY 4 PM for most of the region. A little later in southern Maryland.
Winter Weather Advisory:
This model may be the gold standard but it is not perfect. However, I wanted to show this for you to compare to the HRRR Model for the purpose of:
How far north the impact snow will fall
Southern zones that start with rain or mix, then change to snow.

Official (Maryland) – Most Likely
High End (Maryland): 10% Chance
The winds will be strong, helping to pull in the cold air AND blow snow around. Especially near the Bay and across Delmarva later.
May will have gusts 25 to 35 mph, with some higher surges on Delmarva and by the beaches.
Monday Morning
The Freezing Line will pushing across Southern Maryland to Lower Eastern Shore.
Very cold air will remain across the region throughout the day.
With winds gusting 25 to 35 + mph, the arctic air will feel like the teens. In addition there may be blowing snow and drifting snow, recovering roads.
This seems a bit excessive, but the GFS is trying to allow for clearing and fresh snowpack to support the intrusion of arctic air in the single digits.
