NEAR TERM /THROUGH THURSDAY/... As of 142 PM Wednesday...
A quasi stationary frontal boundary remains oriented west to east across the area through early tonight. In the absence of upper level forcing, expect just isolated to scattered showers or storms to develop this afternoon and evening.

Meanwhile, a new cold front pushes south Thursday morning, pushing any lingering showers out of the area by mid morning.
A Flash Flood Watch remains in effect through 10 PM for the lowlands and until midnight for the mountains. The atmosphere remains very wet today, with diurnal heating, differential heating boundaries, and orographic effects acting as low level forcing. With PWATs around 2 inches, heavy downpours or repetitive storms over the same areas could produce flash flooding.
Models suggest a low stratus deck will develop across most of WV overnight tonight. Areas of fog will be possible, although could be suppressed by cloud cover. Any fog will dissipate by 13Z, and low stratus will lift by 15Z Thursday.
Lows tonight will range from the upper 60s lowlands, into the lower 60s northeast mountains and extreme northern sections. Highs on Thursday will generally be in the lower 80s lowlands, ranging into the mid 60s highest elevations.

Global models are also coming more on board with slight chance POPs for the end of the weekend compared to a much drier solution only days ago.
