DISCUSSION

- 1. Rain chances ending tonight, but daily chances continue through the upcoming week.

This afternoon and evening's thunderstorm activity continues to move out of the area, with just some lingering light rain in the far eastern Midlands and PeeDee. After this activity moves out of the area, the rest of the night is anticipated to remain dry, but a stratus deck is forecast to move over the area.

After today, a closed low is forecast to break off of the main upper trough meandering over the Tennessee Valley for several days. As such, daily chances (30 to 70 percent) for showers and thunderstorms continue through much of the week ahead. Temperatures during the next seven days are forecast to be near to slightly below seasonal values.

AVIATION /00Z MONDAY THROUGH FRIDAY/

Lowering cigs and restrictions expected overnight following widespread rainfall.

Rain is steadily clearing the area this evening with all sites now VFR and rain is east of all terminals. A few showers and storms linger across GA but are not expected to approach any TAF sites. Overnight, cigs will steadily fall to MVFR and then IFR after 08z through Monday morning for TAF sites; generally cigs between 600-1000 feet expected through 14z. Winds will remain light this evening and overnight. Low pressure will struggle to entirely clear the area Monday so some additional showers and storms are likely Monday afternoon.

EXTENDED AVIATION OUTLOOK...Periodic showers-storms expected in the afternoons this week along with cig restrictions in the mornings early this week.

CAE WATCHES/WARNINGS/ADVISORIES
