A slow-moving, mid-level disturbance moving across the Southeast and Mid-Atlantic during the start of this week will allow for scattered showers to develop on Monday and Tuesday and possibly even on Wednesday. With the combination of a little heat and instability as well, that will allow for thunderstorms to form as well, although severe weather is not expected.
On Monday, the activity will be quite isolated with much of the day dry. Once the daytime heat peaks, a few showers and thunderstorms are expected to develop on the leeward side of the App;ahcinas in West Virginia, Virginia, and the Carolinas. A few showers and storms may also pop over Georgia and Alabama. Also during the morning hours farther east, there will be a batch of rain near the DelMarVa and Tidewater of Virginia.
Then on Tuesday, very spotty showers and storms will remain possible in the Southeast and Mid-Atlantic, but most areas only have a 10-20 percent chance for rain. Showers and storms associated with a weak low pressure off the East Coast will allow for the rain showers to persist during the day for the DelMarVa and eastern Virginia.
By Wednesday, the chance for rain will drop off for most, although there is the chance for a few showers and storms in eastern North Carolina.
An approaching cold front incoming from the west will then bring a widespread round of rain and thunderstorms to the interior Northeast and the Mid-Atlantic on Thursday. A few spotty storms are also possible in the southern Appalachians.
Then on Friday, the precipitation will clear out offshore but not before bringing a few showers to the Northeast and eastern Mid-Atlantic Thursday night.
