RAIN CHANCES WILL INCREASE IN COVERAGE ACROSS OUR CWA TODAY AS
MOIST ADVECTION CONTINUES ACROSS THE SOUTHEAST REGION. A FEW
STRONG SCATTERED THUNDERSTORMS CANNOT BE RULED OUT THIS
AFTERNOON. AFTERNOON HIGHS WILL PEAK INTO THE LOW TO MID 90S
AREAWIDE. HEAT STRESS WILL CONTINUE TO BE POSSIBLE TODAY, WITH
PEAK HEAT INDEX VALUES IN THE DELTA REGION NEAR OR A LITTLE ABOVE
105 DEGREES. WILL ADVERTISE A "LIMITED" HEAT STRESS THREAT FOR
THOSE AREAS.
THE FORECAST FOR THE LONG TERM PERIOD REMAINS ON TRACK WITH NO
SIGNIFICANT MODIFICATIONS MADE TO THE OVERALL FORECAST. WEDNESDAY
THROUGH FRIDAY WILL SEE HIGHER COVERAGE IN SHOWERS AND STORMS.
THIS WILL ALLOW FOR DAYTIME HIGHS TO REMAIN NEAR SEASONABLE
LEVELS. DEWPOINTS WILL STILL REMAIN HIGH IN THE MID TO UPPER 70S
WITH THE HOTTEST TIMEFRAME BEING MID MORNING TO MID AFTERNOON EACH
DAY BEFORE ISOLATED SHOWERS/STORMS BEGIN.
GLOBAL GUIDANCE IS STILL SHOWING A TROUGH AXIS OVER THE MID
TENNESSEE VALLEY DROPPING SOUTHWARD ACROSS NORTHERN MS HEADING INTO
THE LATE WEEK. THIS COMBINED WITH DAILY DIURNAL CONVECTION,
FAVORABLE LAPSE RATES AND WESTERLY FLOW COULD ALLOW FOR SOME STRONG
TO ISOLATED SEVERE STORMS TO OCCUR. FORECAST CONFIDENCE IS STILL TOO
LOW AT THIS TIME REGARDING THE TIMING AND INTENSITY OF THIS SYSTEM
GIVEN THE INCONSISTENCY BETWEEN MODEL GUIDANCE. MORE INFORMATION
WILL BECOME AVAILABLE AS WE GET CLOSER TO THE LATE WEEK.
FUTURE GUIDANCE IS STARTING TO SHOW A 1016-1020MB SFC HIGH OVER THE
NORTHERN GULF. TO THE WEST OF THIS HIGH, SOUTHERLY MOIST BOUNDARY
LAYER ADVECTION IS EXPECTED TO CONTINUE ACROSS OUR CWA LOOKING
AHEAD INTO EARLY NEXT WEEK MONDAY. THIS SHOULD ALLOW FOR SCATTERED
SHOWERS/T-STORMS TO PERSIST ACROSS THE AREA WITH SLIGHTLY HIGHER
RAIN CHANCES ACROSS THE PINE BELT.
