SnowenOutThere

Recommended Posts

NAM continues juicy with a good stripe out this way in Loudoun into central Maryland. That would make this a little event.. Now.. everything else needs to fall in line. LOL! I am dreaming, but that looks nice and a lot of the area would have more than a few flakes. 

Maybe happy hour will deliver all around!

:)

EDIT: Well 3KM NAM says.. NOPE - Probably not much to see here! Flakes.. sure!

Mount Holly AFD for the 'event'..

On Tuesday night, the low will be strengthening offshore of the North Carolina coast, before lifting to the northeast through the day Wednesday, remaining offshore of the Mid-Atlantic coast. The ECMWF remains the farthest east with the low as it passes by, while the rest of the model guidance tracks the low farther to the west. The greatest lift/moisture combination within the dendritic snow growth zone will remain on the northwest side of the low, which will track across most of eastern Pennsylvania, New Jersey, as well as Delaware and eastern Maryland. We expect light precipitation to begin around or just before sunrise as a weak lead short wave moves into the area. Then as a stronger short wave approaches after sunrise, we expect the precipitation to spread across much of the area, with the heaviest precipitation across the I-95 corridor, south and eastward. The air above the surface is expected to be below freezing the entire time. However, as the precipitation begins to develop and spread across the area, some areas may warm up to near freezing or slightly above, before wet-bulbing back to freezing or below. So we expect mostly snow for most areas, although some rain may mix in if temperatures warm up above freezing, especially near the coast. QPF amounts are mostly one to two tenths or less across the area, and any snow that falls are expected to remain mostly around an inch or less, although some areas could approach 2 inches if temperatures stay cool enough during the event. The highest amounts are likely to remain across the I-95 corridor south and eastward, before dropping off near the coast.

Its been methodical and incremental for many runs now. The precip area has been getting lighter and shrinking in coverage run after run. Pretty impressive. Not like a sudden "cave". Still, it is now in line with most other guidance, outside of the Euro with its patch of flurries.
