Cool & dry air maintains control over our area today, bringing autumn-like conditions to the Mountain State. Lots of sunshine and almost no humidity making for a perfect couple of days. Near record low temps are on tap tonight. Warmer air mixes back into our area Friday. We'll stay dry Friday & Saturday, with scattered rain showers and a few thunderstorms likely after midnight Saturday & Sunday.

Our skies will stay mostly clear overnight. Temps fall into the low 50s. With plenty of cool air and very little moisture, lows will fall to near record numbers overnight. Some patchy fog will develop into Friday morning but will burn off quickly with sunrise.

Warmer air will begin to lift north, into our area Friday. Still plenty of sunshine is on tap during the day with just a few high clouds possible. Highs will be in the low 80s. Lows Friday will fall into the upper 50s with just a few clouds overnight.

We'll squeeze more fair weather out of the forecast Saturday. Skies will be partly cloudy with lots of sunshine on tap. Highs will be in the low 80s again. But the forecast will diminish quickly Saturday night. An upper level disturbance will cross the Ohio Valley, just south of the Great Lakes. Dew points will be on the increase Saturdya afternoon, reaching the mid 60s. So more humidity will gradually return to the forecast over the weekend. Scattered rain showers and thunderstorms will develop Saturday evening ahead of the frontal boundary. Any storms that do fire late Saturday & Sunday could still produce heavy downpours in spots. Brief periods of strong gusty winds are also possible as the front pushes through during the day on Sunday.

A few leftover showers cannot be ruled out Sunday night into Monday. But high pressure ridging will return to the forecast to bring dry air and more sunshine late Monday & Tuesday next week. Chance for rain will return Wednesday night.
