.DISCUSSION...

A humid airmass in place across the area with dewpoints in the low
70s. Current radar imagery indicates a few scattered
showers/storms north of I-40 and east of I-75 and increased PoPs
in this area over the next few hours. Also increased cloud cover
throughout the day with the ridge weakening and a few weak
shortwave troughs approaching from the northwest. Expect there
will be better coverage of showers/storms this afternoon with best
chances in NE TN and SW VA. The cloud cover should keep SBCAPE
values in the 1000-1500 J/KG range with deep layer shear values
around 10 kts. Overall, there could be a storm or two that pulses
up to become strong to marginally severe but do not anticipate any
widespread severe weather threat.
