FORECAST DISCUSSION
Normal high: 51°F. Normal low: 32°F.
We're going to briefly see some milder temperatures on Delmarva before a quick snow event brings cold and blustery conditions.
High pressure built in during the day on Friday, keeping a weak clipper system well to our south, and setting us up for a clear and cold Friday night.
As the high slides to the east, winds will shift to the south, pushing a weak warm front up the East Coast. This will bring a day of milder (although still several degrees below normal) temperatures on Saturday, as clouds increase ahead of our next weather-maker.
Confidence is continuing to increase that a clipper system will bring some accumulating snowfall to Delmarva Sunday morning. Clipper systems don't typically have a lot of moisture, so we're not expecting blockbuster snowfall. But a few inches of accumulating snowfall is increasingly likely, mainly over the Maryland Midshore and Delaware. An inch or two is expected on the Lower Eastern Shore, with little to no accumulation expected at this time along the Atlantic Coast and over Accomack County.
The clipper system will clear out quickly and snow should taper off by Sunday afternoon as a bitterly cold air mass builds in.
Expect cold temperatures and gusty northwest winds late Sunday into Monday. Blowing snow could cause travel troubles into Monday.
Milder temperatures make a return by the middle of next week.
In the long range, temperatures are expected to average above normal, and precipitation below normal for December 19 - December 23.
