PROMPTED A FEW FLASH FLOOD WARNING/EMERGENCY ACROSS PORTIONS OF
SOUTHERN COUNTIES (JEFF DAVIS, COVINGTON, AND JONES COUNTIES).
PATCHY FOG WILL BE POSSIBLE IN THE PRE-DAWN HOURS THIS MORNING.
TROPICAL MOISTURE FROM THE REMNANTS OF TROPICAL STORM ARTHUR ALONG
WITH AN APPROACHING FRONTAL BOUNDARY WILL CONTINUE TO PROVIDE
SHOWERS AND THUNDERSTORMS OVER THE COURSE OF FRIDAY. AHEAD OF THE
SHOWERS/STORMS, TEMPS/DEWPOINTS WILL BRING HEAT INDICES NEAR 115 IN
THE SOUTHWEST PORTION OF THE AREA. A HEAT ADVISORY WITH ACCOMPANIED
GRAPHICS WILL BE ISSUED. DURING THE AFTERNOON HOURS, A MARGINAL RISK
FOR SEVERE WEATHER IS EXPECTED ACROSS THE CWA. DAMAGING WINDS AND
ISOLATED HAIL IS EXPECTED WITHIN SEVERE STORMS. FLOODING WILL
CONTINUE TO BE OF CONCERN, ESPECIALLY NEAR THE PINE BELT AS STORM
TRAVERSE OVER AREAS THAT HAVE RECEIVED 3-4+ INCHES OF RAIN SO FAR.
WET PATTERN WILL CONTINUE INTO THE WEEKEND AS A SHORTWAVE TROUGH
MOVES OVER THE LOWER MS RIVER VALLEY AND INTERACT WITH THE
AFOREMENTIONED FRONTAL BOUNDARY THROUGH THE WEEKEND. CAM MODELS
SUGGEST THE FORMATION OF COUPLE OF MCSS NEAR TX/AR THAT WILL HEAD
TOWARDS OUR AREA. WITH THE PREVIOUS RAINFALL, SATURATED SOIL, AND
STORM TRAINING, FLOODING WILL REMAIN A CONCERN.
MONDAY THROUGH THURSDAY:
HIGH PRESSURE OVER AZ/NM AND NORTHERN MEXICO AND LONGWAVE TROUGHING
OVER THE GREAT LAKES/OHIO REGION WILL SET UP THE NEXT CHANCES FOR
RAIN. MULTIPLE SHORTWAVE DISTURBANCES ARE EXPECTED TO TRAVERSE OVER

NOTHING HAS BEEN OUTLOOKED AT THIS TIME. /SW/
