Low pressure waivering over the east coast sets up spotty rain showers & generally overcast skies into Thursday. Mild temperatures & widespread morning fog are on tap through the first half of this week as well. High pressure with gradual warming and and clearer skies arrive Friday, into the weekend.

For tonight, lows will fall to the upper 40s. Low pressure center will slowly press north, tossing lots of low level moisture into our area. Fog will develop early Tuesday. We'll see more widespread rain showers, especially to the south where daytime highs will reach slightly warmer than to the north. Highs will be in the mid to upper 60s Tuesday.

Another upper level disturbance is on track for Tuesday night/Wednesday. This will bring generally cloudy skies & scattered rain showers Tuesday & Tuesday night. Otherwise we can epect lows in the low 50 to mid 50s.

Rain showers & a few thunderstorms are possible Wednesday. A few peaks of sunshine will begin to break out as well. This will add  instability & potential for locally heavy downpours, dangerous lightning & hail. Five-day rain totals paint more than one inch of rain for much of West Virginia. With more than four inches of additional rainfall expected furher east, from Monday morning through Saturday AM flooding concerns may arise along the Potomac Valley towards the end of the week.

A few leftover rain showers are on tap for Thursday. Temps will be in the low 70s. High pressure will build into the area by Friday. This will provide clearer skies, sunshine and slightly warmer temps for Friday & Saturday. Then more rain arrives by Sunday.
