DISCUSSION

Key message 1: A cold front keeps shower and possibly thunderstorm chances around through Friday before dry conditions return this weekend. Highs remain above normal through Friday with cooler conditions afterwards.

Deep moisture remains over the area through Friday morning as a cold front slowly approaches the area. This keeps scattered showers, and possibly a few thunderstorms, in place tonight into Friday morning. QPF will generally be light, but some moderate rainfall is possible in any storms that develop. Low temps tonight will be up to 20 degrees above normal.

The cold front pushed through on Friday bringing in drier air and an end to the showers by afternoon, but highs remain around 5 degrees above normal as cooler air is delayed until Friday night.

Temps fall below normal for the weekend. Saturday night will be the coldest night but only slightly warmer Sunday night. Freezing temps will be possible for the NC foothills with frost possible for the NC Piedmont, potentially reaching the eastern Upstate as well. Dry conditions with a slow warming trend expected through next week.

AVIATION /18Z THURSDAY THROUGH TUESDAY/

At KCLT and elsewhere: Breaks have developed across the area with generally low VFR to MVFR cigs. These will continue through the afternoon with VFR vsby, except MVFR in the scattered showers over the area through the afternoon. Expect low VFR cigs for the evening with showers ending. Low level moisture remains in place though so MVFR to IFR cigs return overnight. LIFR can't be ruled out. Some fog will develop, generally MVFR but IFR or lower is possible at KHKY. KCLT will also see showers redevelop before daybreak and continuing through the morning. Expect the low clouds to scatter out from west to east through the morning with VFR by afternoon. S to SW winds this afternoon, with low end gusts possible, become light and variable overnight, then pick back up from the N to NW during the day Friday.

Outlook: VFR conditions expected this weekend into early next week. The exception will be an eventual return of mountain valley fog.
