DISCUSSION

KEY MESSAGE 1. Not as hot or as stormy for Labor Day. Temperatures and rain chances increase as the week goes on.

After an active weekend across much of the FA, Labor Day looks more tranquil. The upper trough axis pushes to our east today in response to building ridging over the Central CONUS. Northeasterly winds should promote drier air and lower daytime temperatures today with forecast highs in the lower 80s. The best rain chances will be across the southern Midlands and CSRA, dropping quickly after sunset as lower PWATs infiltrate the CWA from the northeast and surface high pressure sags south into the region. With upper ridging and high pressure in place Tuesday and Wednesday, near to slightly above normal temperatures are expected with low rain chances. The pattern shifts later this week with scattered showers and thunderstorms more likely during the Thursday to Saturday timeframe as upper ridging breaks down.

AVIATION /06Z MONDAY THROUGH FRIDAY/

Increasing confidence in cig restrictions due to stratus as a frontal boundary shifts southward through the area.

Satellite imagery showing some lingering convective debris high clouds and some lower clouds forming across parts of the northern and central Midlands. Hi-res guidance is continuing to hint at stratus development across the region through mid morning before conditions improve back to VFR through the afternoon. Northeasterly winds at around 5 knots should develop after 09z and shift to more easterly winds around 10 knots after 15z. Isolated showers are possible this afternoon mainly focused across the CSRA so will include a prob30 at AGS/DNL.

EXTENDED AVIATION OUTLOOK...Diurnal storm chances continue into the first half of the week.
