353 PM CDT Wednesday Sep 2 2015

Short term...tonight through Thursday night...as we go into
tonight...convection from today should diminish with overnight lows
around 70. A weak upper low will be pushing into the region tonight
into Thursday. With model cross sections showing dryer air aloft
moving over the region on Thursday...expect mostly isolated to low
end scattered diurnal convective coverage for Thursday into Thursday
evening. High temperatures on Thursday should be warmer...mainly in the middle
90s. /27/

Long term...Friday through next Tuesday...typical late Summer
conditions will continue Friday...over the weekend...and into early
next week. Highs each afternoon will climb into the 90s... with
lows falling down around 70 each night. Low-end rain chances...
generally 20-30%...will exist over most locales through much of the
period. However...slightly better rain chances...30-50%...look to
exist over much of the County Warning Area Sunday...then over south Mississippi
Labor Day and Tuesday as another upper level low is prognosticated to shift
south southwest skirting the eastern half of the County Warning Area during that
time frame. Convection will remain confined primarily from middle-
afternoon up to sunset. As daytime heating wanes...activity will
dissipate. /19/

Aviation...mid/high clouds have persisted over the central portions
of the area inhibiting convection so far this afternoon. Isolated rain showers/thunderstorms and rain
activity has developed over the east and west where insolation has
occurred. Isolated to scattered thunderstorms and rain activity may lower flight cats to MVFR
briefly this aftn/evng. Otherwise...VFR conds will continue through this
evening. A brief period of MVFR visibilities 10-13z Thursday will be possible at most taf
sites. /22/
