Mid-Atlantic – The Week Ahead (Feb 20-27)

Today will be the calm before the storms as a two-part system brings rain, mixed precipitation and snow to the region Monday and Tuesday. The rain will start early tomorrow across PA and edging into northern MD as the first piece of energy pushes through. As the light/moderate rain pushes further south into northern VA, all of MD and Delmarva, a changeover to mixed precipitation and finally snow will occur on the northern edge of the precipitation. Temperatures will crash from the 60s Monday afternoon into the low to mid 30s Tuesday morning. Because of the warmer temperatures and rain to start, snow will have a hard time sticking to the ground from DC southward, if it even snows at all in the southern parts of the region. Snowfall totals of 1-2″ (and local totals of 2-4″) are possible from just north of DC to the MD/PA line, with 2-4″ (and locally 4-6″) north of the Mason-Dixon and in the western Appalachians. Most of the snow will fall early Tuesday, with some snow showers lingering past morning rush hour.

High pressure will move into the region to keep things quiet until the front edge of another system moves into the region on Thursday. Heavy rain and a maybe thunderstorms will be possible with this next system, with a possible changeover to a little snow at the back-end of the storm in the northern and western parts of the region.

After this system exits the region Friday night, there will be a brief break in the wet weather until yet another storm moves in early on Sunday, which will bring more rain and maybe some snow into the region. Next Sunday’s storm has some big snow potential to the north of the region, and it will be something to keep track of for our region as well.
