     Blue skies appear today as a few peaks of sunshine manage to punch holes in some of cloud cover over the Mountain State. Remnants of Lee gradually dissipating over the Ohio Valley. Water levels in local creeks and streams steadily receding. Flash flood warnings for West Virginia have expired with the exception of the Eastern Panhandle, where the threat for showers & storms over DC/VA lingers into Thursday. Meanwhile, upper level low pressure will interact with leftovers from Lee to keep residual bands of rain & thunder in the forecast now through the weekend. Temperatures won't change very much with highs reaching the upper 70s/low 80s. Overnight lows will fall to near 60.

     For today...leftover low pressure from Lee will actually waiver west, into the Ohio Valley. Our area will stay dry for much of the day today as a 'dry slot' develops over much of the Mid-Atlantic states. But the weakening system will continue to interact a deep upper level trough to produce broken cloud cover and spotty showers. Partly sunny skies will help put highs near 80 today. By early evening, a few pop up thunderstorms may develop across our area. Again, flash flooding concerns have faded but any locally heavy downpours that do crop up could have a major impact on areas that have been dumped on.

     Overnight...skies will be partly/mostly cloudy. We'll keep a chance for rain showers and an isolated storm, especially in the mountains. Otherwise, calm conditions will allow patchy fog to develop into early Thursday. Lows fall to near 60.

     For the rest of this week...Thursday, low pressure from Lee hung up west of the Appalachians will keep the threat for spotty showers and thunderstorms, especially further east. The slowly weakening system will gradually be pulled apart, producing less & less severe weather threat by the weekend. However, the unsettled forecast will linger into the weekend as another upper level disturbance provides the chance for afternoon & evening thunder Saturday & Sunday. Temperatures through the weekend will range from upper 50s/low 60s to near 80 each day.
