High pressure over the southeast will slowly move eastward through the day,
with low and mid level winds transitioning to out of the southwest by 
tonight. This afternoon, there is just enough instabiltity, roughly between
2000 and 2500 J/kg for isolated showers and a rumble of thunder to develop, 
though forcing and moisture will be weak. Left in a slight chance for
activity this afternoon, weakening around sunset. Overnight through Tuesday,
a low pressure system moves through the Ohio Valley with a frontal boundary
approaching from the northwest. CAMs are fairly consistent that the boundary
should slowly slide into the northwest by the evening, lingering over the 
north and west parts of the area into the evening and overnight hours. 
Moisture is expected to increase from the 50th percentile today to the 90th
percentile by Tuesday afternoon. There will be plenty of moisture, lift,
shear, though instability will be low as the front moves in. Scattered 
showers and thunderstorms are likely to develop along this boundary, with 
activity developing and moving southwest to northeast, with training storms
possible.
