Active Weather Today; Calmer Weekend

Today will feature scattered showers and thunderstorms as a cool front moves in through the Ohio Valley. Showers and storms linger through the evening as the front passes overhead. High pressure begins to build in overnight. Saturday will feature patchy fog early and partly sunny skies as we begin to dry out. Sunday will be much like Saturday, with a "cannot rule out" mention of an afternoon shower or t-shower. This trend continues through Monday. More active weather returns Tuesday ahead of our next frontal system.

Forecast Discussion

Unstable air in place across the region allows for scattered development of showers and storms today as a front moves in late today from the Ohio Valley. High pressure builds overhead Saturday behind the front letting us dry out a bit for the weekend. We expect some areas of patchy fog early Saturday and cannot rule out a stray shower during the late afternoon, the same can be said for Sunday.

The nice and mostly dry stretch extends into Monday with only a mention of an isolated showers or t-shower with high pressure in place. High pressure shifts off the Southeast coast by Tuesday. This allows a warm and moist southerly flow to set up from the Gulf of Mexico. The result will be more warm and humid air moving in and increasing instability producing widely scattered showers and storms.

Our next front dips out of the Upper Midwest into the Ohio Valley for Wednesday with more scattered showers and storms. The stormy Wednesday is followed by a bit of a cool-down Thursday and Friday as cooler high pressure settles across the region. It will be drier and quite nice.
