DISCUSSION

KEY MESSAGE 1: Cooler but dry conditions are expected into the weekend. Temperatures gradually return to near to above normal values next week.

Rain showers have largely come to an end at this point, though a few patchy spots of drizzle could still be possible over the coming hours. After this, mostly dry, but cloudy conditions likely persist overnight as the wedge remains in place, though drier air should start to work in with weak CAA overnight tonight. This should bring cooler low temperatures that MOS guidance consistently has indicated should bottom out in the low to mid 50s! Southern spots could be a tad warmer.

A pleasant first weekend of autumn is expected as high pressure moves into the region and the wedge completely erodes. Models currently have the wedge retreating from our area early Friday, though guidance tends to handle the progression of such events poorly. As such, would expect the start of Friday to remain on the cooler and cloudier side. After that, mostly clear skies and dry conditions prevail with highs rebounding each day and trending closer to normal and eventually above normal. Max temps Friday and Saturday will reach the mid to upper 70s and lower 80s, with overnight lows generally in the lower 50s. CAA will help dip dewpoints into the 40s and 50s, making it feel beautiful for the next few days. Looking ahead, daytime temperatures warm back into the mid-80s by the middle of next week as the pattern looks to evolve toward something more damp. However, details remain uncertain at this time.

AVIATION /00Z FRIDAY THROUGH TUESDAY/

Improvement expected at all terminals over the next few hours with VFR conditions and breezy northeast winds the remainder of the period.

Clearing being observed over North Carolina as drier low level air continues to filter into the Carolinas and Georgia tonight. Expect improvement in ceilings over the next several hours as MVFR ceilings gives way to VFR ceilings (around 4kft) and then finally to clear skies by early Friday morning. May be a bit more pessimistic with the clearing then some of the guidance but guidance does tend to break up the wedge a bit early. Breezy northeasterly winds continue through the day tomorrow as low pressure deepens off the coast with clear skies continuing through the day.
