.DISCUSSION...
The low pressure system that has been around since the weekend,
moves away from the area today and tonight. As a result, the chance
for showers comes to an end over the middle Ohio Valley by this
afternoon, and in the central Appalachians tonight. There may be fog
by Wednesday morning, as the higher clouds thin out, and the wind
becomes very light or calm.

Wednesday looks to be sunny and warm, under the influence of high
pressure.

A cold front will cross Thursday afternoon and evening, kicking off
thunderstorms out ahead of it.  After brief high pressure on Friday
we will see a warm front lift northward this weekend.  This front
will increase moisture and temperatures across the region.  As such,
we can expect unsettled weather with showers and storms at times
through the weekend.
