High pressure and a few peaks of sunshine helped put temperatures in the 50s today. That high pressure ridge will slide east as strong low pressure from the Central/Southern Plains moves into the Ohio Valley tonight. Thick cloud cover will keep temperatures at or just below freezing tonight. We'll stay dry tonight but there's a slight chance for light mixed precip after midnight.

We'll see winds picking up tonight into Wednesday, especially in the higher elevations. Again, the thinking with this system is that plenty of Gulf Coast moisture will accompany the low pressure system. Some rain may be heavy at times and the odd thunderstorm cannot be ruled out  as the system develops...1.5 inches of new rainfall is expected through Thursday. With many creeks already swollen from recent rainfall, a flood watch is already in effect now through Thursday evening for much of the forecast area. Folks near flood-prone areas would do well to keep a close eye on water levels through Thursday evening.

As that system progesses in a generally northeasterly direction, cold air on the backside of the front will turn any lingering precip over to mixed precip Thursday night with some light accumulation, especially in the higher elevations continuing into Friday. Things will gradually dry out for the rest of the day Friday...We start dry and mild with some sunshine Saturday. But another system will arrive as we set our clocks forward Saturday/Sunday with limited moisture just tossing a few clouds our way. Temperatures will stay on the mild side this weekend.
