A tricky forecast unfolds through the end of the week...A weak disturbance brings a chance for isolated afternoon and evening thunderstorms. Friday's forecast will be mostly cloudy but mainly dry with temps reaching the mid 80s. Threat for rain/storms returns Friday night into early Saturday. We'll eek by with some sunshine & a mainly dry forecast for Saturday. Then a stronger wave brings better rain chances Sunday.

For tonight...increasing cloud cover is expected as a weak front brings limited moisture into our area. Nearly saturated air aloft and plenty of daytime heating could trigger a few showers and thunderstorms early this evening into the overnight hours. Main threat for showers & storms will be in our mountain counties and in the Eastern Panhandle of West Virginia. Lows tonight will fall into the low 60s.

Friday's forecast will start mostly cloudy with a few leftover rain showers. But weak high pressure will provide slightly drier air for much o the day. Some sunshine will still reach the surface so I see no reason why highs won't be about the same as today. So look for variable clouds with highs in the mid 80s again. Forecast will stay mainly dry through the afternoon & evening but rain showers and isolated storms are possible Friday night into the wee hours of Saturday morning. Lows will be in the low to mid 60s with thicker cloud cover keepin' things relatively warm.

Warmer air will lift north into our area during the day Saturday. Highs will reach the low/mid 80s. Some sunshine is still on tap during the day. But that sunny forecast will erode quickly Saturday afternoon & evening. A quick short wave disturbance will cross our area bringing the threat for an isolated afternoon storm Saturday through Saturday night.

Another stronger, well-defined front will develop west of our area Sunday. So we'll keep the threat for scattered rain showers and thunderstorms Sunday evening into early Monday. Slightly cooler air is on tap for the beginning of next week. But the second half of next week looks hot at the moment.

A look at the extended shows a strong Atlantic Coast cyclone running across Hispaniola & Cuba next week...Looks like it may become a tropical storm or hurricane & run against Florida & up the Atlantic coast by next weekend...Will keep on eye on that for ya & report my findings!
