DISCUSSION
Key Message 1: Near normal temperatures into the weekend with dry conditions. Diurnal rain chances return early next week.
Surface high pressure and deep ridging will dominate the pattern through the weekend. Today into Saturday will be quite dry, with PWATs around 50-70% of normal and afternoon dewpoints falling into the 50s. Low level moisture starts to return Sunday into early next week on the back side of the surface high and some weakness in the upper ridge leading to stronger westerly flow aloft. High temperatures should be within a few degrees of 90 each day into the middle of next week with small NBM interquartile ranges indicating fairly high confidence. Rain chances should hold off until Monday when sufficient moisture remains in place as a series of shortwaves starts to traverse the region. As such, diurnal scattered showers and storms are then expected most days next week with a fairly typically summer pattern in place.
AVIATION /16Z FRIDAY THROUGH TUESDAY/
VFR conditions remain likely through the TAF period.
Dry high pressure remains anchored over the region. Afternoon winds will gradually diminish this evening, becoming light and variable overnight. The dry airmass should limit fog development, although a few localized areas of river fog cannot be completely ruled out early tomorrow morning. Confidence in any fog impacting the terminals remains low.
A few patches of thin cirrus will spread across the area later this afternoon and persist into Saturday. South to southwest winds will increase to around 5 to 8 kts by midday, resulting in conditions very similar to those observed over the past several days.
EXTENDED AVIATION OUTLOOK...Drier air continues to hang on through the weekend with mainly VFR conditions expected. Some increase in moisture and rain chances Monday into Tuesday could bring periods of restrictions in showers/storms.
CAE WATCHES/WARNINGS/ADVISORIES
SC...None. GA...None.
