February 8- A Winter Storm Warning has been issued for central Maryland, contrasted with A Winter Weather Advisory or Winter Storm Watch in other places. This is a classic example of variety of weather and National Weather Service Offices that cover our area. Please keep in mind that my forecasts are my own, but I like to let you compare to outer sources. All watches and warnings come from the government- aka National Weather Service. It is designed to help, but sometimes can be confusing. I want to clarify what this means, plus give an update on the forecasts model snow cast maps.I am staying with my snow cast, and you can see that map for comparison below.
UPDATE: The Winter Storm Warning was expanded into southern PA.
Winter Storm Warning:
- 10 AM Monday through 6 AM Wednesday.
- Harford, Baltimore (city and county), Anne Arundel, Howard, Carroll, Frederick, and northwestern Montgomery Counties in Maryland.
- Start as rain, changing to moderate snow by midnight. Snow most of Tuesday.
- General 4 to 8 inches of snow (according to NWS). This overlaps with my forecast zones for 3″to 6″ and 5″ to 9″.
Winter Weather Advisory
- Metro Washington and western Maryland.
- General 1 to 3 inches of snow (according NWS). This is close to my zone for 1″ to 3″.
Winter Storm Watch
- Southern Pennsylvania, northern Delmarva, metro Philadelphia.
- This will be upgraded to an Advisory or Warning shortly. These areas are under the National Weather Service Office in State College PA or Mount Holly NJ. It really is just their timing issue. They usually wait until later in their shifts to do their upgrades but adjacent to the Maryland Counties in the Warning can be confusing.
Notice the system now displaying what we’ve discussed for a few days: This will start as rain, then turn to snow and develop right on top of us.
