AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
243 PM CDT SAT AUG 9 2014

.SHORT TERM...TONIGHT THROUGH MONDAY NIGHT...MID 70 DEWPOINTS ALONG
WITH MID 90S TEMPS ARE YIELDING CAPES NEAR 4000 J/KG AND PROLIFIC
CONVECTIVE DEVELOPMENT OVER CENTRAL PORTIONS AT PRESENT. THESE
VALUES...ALONG WITH VERTICAL TOTALS NEAR 28 AND DCAPES NEAR 1000 J/KG
ARE SERVING TO ENHANCE THE WET MICROBURST POTENTIAL THIS AFTERNOON.
THIS CONVECTIVE POTENTIAL WILL LINGER INTO THE EARLY EVENING HOURS
BEFORE DIMINISHING WITH THE LOSS OF HEATING.

NEAR TROPICAL AIRMASS WILL REMAIN IN PLACE THROUGH THE PERIOD WHILE
A QUASI STATIONARY BOUNDARY REMAINS ANCHORED OVER AR/W TN. THESE
FEATURES WILL ALLOW FOR A CONTINUATION OF THE PRESENT WEATHER
SCENARIO WITH OVERNIGHT CONVECTIVE DEVELOPMENT NEAR THE BOUNDARY AND
OUTFLOWS FROM THAT CONVECTION MOVING SOUTHEAST TO INITIATE DIURNAL
CONVECTION IN OUR CWA. THIS INCREASED CONVECTIVE DEVELOPMENT LOOKS
TO BE A GOOD BET BOTH SUNDAY AND MONDAY AS LOW/MID 70S DEWPOINTS
WILL YIELD CAPES FROM 4000-5000 J/KG AS MAXES WARM INTO THE LOW/MID
90S. THESE TEMP/DEWPOINT COMBINATIONS WILL ALSO ALLOW HEAT INDICES TO
JUMP TO THE 100-105 RANGE. WILL CONTINUE TO ADDRESS THIS IN THE HWO.

MID/UPPER LEVEL FLOW PATTERN WILL REMAIN WEAK THROUGH THE MAJORITY
OF THIS PERIOD...ALTHOUGH CHANGES ARE ON THE HORIZON. MID LEVEL HIGH
CENTER...WHICH HAS BEEN MEANDERING ALONG THE NORTHERN GULF
COAST...WILL BEGIN RIDGING WEST MONDAY. THIS WILL ALLOW MID LEVEL
TROFFINESS IN THE EAST AND A SURFACE COLD FRONT TO MAKE A RUN TOWARD
THE CWA MONDAY NIGHT. CONVECTION LOOKS TO CONTINUE OVERNIGHT MONDAY
NIGHT...ESPECIALLY IN THE NORTH...INSTEAD OF WANING AFTER THE LOSS
OF HEATING. A NICE AIRMASS CHANGE LOOKS POSSIBLE MOVING INTO MID
WEEK./26/

.LONG TERM...FOR THE MED RANGE/LONG TERM (TUE-SAT)...BY MID
WEEK...LOOK FOR A MORE QUIET REGIME WITH LOWER HUMIDITY BEFORE WARMER
CONDITIONS RETURN BY NEXT WEEKEND. THE NW FLOW PATTERN WILL REALLY
TAKE HOLD OF THE REGION BY TUE WITH ALL MODELS SHOWING A WELL DEFINED
MID LEVEL DRY PUSH MOVING SOUTH INTO THE AREA. THIS WILL SERVE TO
HELP THE WEAK SFC FRONT TO MAY HEADWAY WELL INTO THE CWA ON
TUE...THEN BRING SOME DRIER LOW LEVEL AIR IN ITS WAKE. PRECIP
ACTIVITY ON TUE WILL MAINLY BE CONFINED TO THE SOUTH HALF AND MOST
LIKELY EARLY IN THE DAY PERIOD. AS WE GO INTO AND THROUGH MID/LATE
WEEK...THE NW FLOW PATTERN WILL RELAX AND RIDING LOOKS TO BUILD OVER
THE LOWER MS RIVER VALLY INTO THE WEEKEND. THIS SHOULD SUPPORT SOME
NEAR NORMAL OR SLIGHTLY BELOW NORMAL HIGHS FOR WED/THU ALONG WITH
LESS HUMID READINGS. BY FRI/SAT...A RETURN TO MORE NORMAL CONDITIONS
ARE EXPECTED. /CME/

&&

.AVIATION...SCT TO NUM SHRA/TSRA ACROSS CENTRAL AND SOUTH MS THIS
AFTN WHICH HAVE RECORDED MVFR AND IFR CATEGORIES AT SEVERAL TAF
SITES WITH 30-40 KT GUSTS. WILL CONTINUE TO AMEND ACCORDINGLY
THROUGH THIS AFTERNOON. TSRA/SHRA ACTIVITY WILL CLEAR CENTRAL SITES
NEXT 1-2 HOURS WITH KMEI BY 21-22Z AND KHBG LATER INTO THE EARLY
EVENING. PERIODS OF MVFR FOG POSSIBLE OVERNIGHT 09-13Z WITH ANOTHER
ROUND OF SCT/NUM TSRA DURING SUNDAY AFTN. /ALLEN/
