NEAR TERM...
(Now through Sunday)
Issued at 435 AM CDT Sat Sep 23 2023

Upper level flow becomes northerly today as the area is between a trough over the east coast and an upper ridge to the west.
Meanwhile, a northerly low level flow will develop across the area as TS Ophelia moves across portions of eastern North Carolina and southeastern Virginia. This will bring very dry air into the area with precipitable water values dropping below 1 inch across eastern portions of the area. The deep layer northerly along with mid/upper subsidence will maintain mostly clear skies with dry conditions through the period. Highs will be in the upper 80s and low 90s. Humidity levels will also be rather low as dewpoints mix out into 50s during the afternoon hours. /13

SHORT TERM...
(Sunday night through Monday night)
Issued at 301 PM CDT Fri Sep 22 2023

A combination of a closed upper low over the southern Gulf of Mexico and upper level shortwave energy moving east over the Lower Mississippi River Valley into a westward shifting upper level trough over the Southeast is expected to bring moisture back over the forecast area. By Tuesday morning, precipitable h20 levels rise back into the 1.5"-1.7" range over most of the forecast area, with a residual band of lower values stretching southwest over the I-65 corridor. Showers and thunderstorms begin to push east over western portions along with from the south over coastal/open Gulf areas, but the drier band over the I-65 corridor will help to limit inland coverage of convection over the majority of the forecast area in the Short Term.

With the increase in moisture levels, low temperatures will see an increase. Low 60s over northeastern portions of the forecast area to around 70 over southeast Mississippi and the coast Sunday night rise to the mid 60s to low 70s Monday night. High temperatures see little change, ranging from the upper 80s to low 90s, well above seasonal norms.

LONG TERM...
(Tuesday through Friday)
Issued at 435 AM CDT Sat Sep 23 2023

The mean upper trough over the Southeast shifts west a bit more, then takes a positive tilt. A surface ridge builds southwest along the Appalachians in response to the tilting upper trough, bringing a return of drier northeasterly flow to the Southeast and for the forecast area, mainly northeastern portions of the forecast area. The tilting of the upper trough in combination with the influx of drier air shifts an increase in showers and thunderstorms mid week southeastward, to along and south of the Gulf coast by the end of the week. Temperatures remain well above seasonal norms over the southwestern half of the forecast area, dropping closer to seasonal norms over the northeastern half of the forecast area by the end of the week as cooler, drier air begins to move over the forecast area.

No impacts expected other than locally higher winds and seas possible near thunderstorms early next week. /13
