SYNOPSIS
High pressure along with dry weather and near normal temperatures are expected through Thursday. Unsettled conditions are possible by late in the week into the weekend as moisture moves in from the Atlantic. Well above normal temperatures are expected by Sunday into early next week.

NEAR TERM /THROUGH TONIGHT/
Upper level ridge remains centered over much of the eastern US with drier air aloft. At lower levels, an onshore flow will continue through the night. Skies tonight should be partly cloudy, with some high clouds moving in from the northwest, while in lower levels few to scattered clouds will remain possible with the onshore flow. Winds remaining 5 to 10 mph overnight. Lows tonight in the mid 60s.

SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/
High pressure remains in place at the surface and aloft Thursday as the pattern will be similar to Wednesday. Weaker onshore flow will lead to less moisture, especially in the low levels so while scattered cumulus may develop, showers are not expected as PWATs will struggle to exceed an inch. High temperatures expected to be near today's highs. A weaker low level jet Thursday night along with drier conditions should lead to overnight lows being a degree or two cooler, in the mid 60s.

Gradual warming expected into Friday as the upper ridge retrogrades and will be centered over the TN Valley. Temperatures at 850mb rise to near or slightly above normal, leading to highs in the low to mid- 90s across the forecast area. A surface trough located offshore will begin to move towards the area around the flow of the upper ridge.
This will lead to increasing moisture flowing into the forecast area, although models remain consistent in keeping the deepest moisture to the south. PWATs increase sufficiently to support at least a chance of afternoon showers and thunderstorms south of I-20.
This increased moisture will also lead to warmer overnight lows, in the upper 60s to around 70.

LONG TERM /SATURDAY THROUGH WEDNESDAY/
Warming is expected to continue into this weekend as upper ridging continues to hang on over the Southeast. NAEFS indicates that by Sunday and Monday, 850mb temperatures will exceed the 90th percentile. Little change in the overall high temperature forecast in blended guidance or the spread through at least Monday with high confidence (greater than 70%) in high temperatures exceeding 95F each day. With sufficient low level moisture (dew points around 70F), confidence continues to increase in max heat indices reaching or exceeding 100F Saturday through Monday. Also worth noting that blended guidance continues to favor warm overnight lows, remaining in the low to mid 70s. There remains uncertainty beyond Monday as guidance continues to show the ridge beginning to break down as an upper trough approaches the region and blended guidance begins to show greater spread in temperatures. That being said, no major cool down is expected anytime soon. GEFS probabilities indicate increasing probability of PWATs increasing to above 2 inches by Sunday into early next week which will lead to increasing chances for diurnally driven thunderstorms. With the potential for greater dynamics with an approaching upper trough, highest chances for showers and thunderstorms will be Monday and Tuesday.

More information on the potential for moderate to major heat risk late in the forecast period can be found at wpc.ncep.noaa.gov/heatrisk.

AVIATION /00Z WEDNESDAY THROUGH MONDAY/
VFR expected through the TAF period.

The cumulus field continues to dissipate with the loss of daytime heating. Expect clear skies to overtake the area shortly after 00z and continue through about 15z before fair weather cumulus develop once again. Easterly winds from 5-10 kts diminish some overnight and shift to northeasterly. Expect winds to become more easterly and gust to 15 to 20 kts after 15z.
Fog development is not anticipated overnight as winds are not expected to become calm.

EXTENDED AVIATION OUTLOOK...Brief restrictions possible in isolated to scattered afternoon and evening thunderstorms Friday through Sunday.

CAE WATCHES/WARNINGS/ADVISORIES
SC...None.
GA...None.
