Widely scattered showers and thunderstorms developed across portions of southwest Arkansas during the late afternoon and early evening hours. These were heat induced thunderstorms that were pulse type storms that produced strong wind gusts upon decay and cloud to ground lightning.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
316 PM CDT SUN AUG 15 2010
.DISCUSSION...
PROBABLY THE HOTTEST DAY OF THE YEAR ACROSS THE REGION TODAY...AT
LEAST CONCERNING HEAT INDEX VALUES. SEVERAL LOCATIONS TODAY ABOVE
A HEAT INDEX TEMPERATURE OF 110 DEGREES INCLUDING A 115 AT SHV
AND MLU. THE EXCESSIVE HEAT WARNING RUNS THROUGH 8 PM WITH A BROAD
HEAT ADVISORY FROM 8 PM THIS EVENING THROUGH 8 PM MONDAY EVENING
WILL REMAIN UNCHANGED.
SFC ANALYSIS AS OF 18Z SHOWING THE COOL FRONT NEAR A MEM...LIT...
TO SPS LINE AND SLOWING. WIDELY SCATTERED CONVECTION HAS FIRED
AHEAD OF THE BOUNDARY ACROSS THE MIDDLE RED RIVER VALLEY OF SE
OK/SW AR AND NE TX...AS WELL AS N CENTRAL AND NE LA THIS AFTN.
EXPECT THE CONVECTION SOUTH OF THE I-20 CORRIDOR TO SLOWLY
DISSIPATE THIS EVENING BUT THE CONVECTION ALONG AND NORTH OF THE
CORRIDOR TO WEAKEN IN COVERAGE AND INTENSITY LATE THIS EVENING...
THEN POSSIBLY REFIRING LATE TONIGHT...THUS CHANCE COVERAGE ACROSS
OUR NORTHERN ZONES AND SLIGHT CHANCE FURTHER SOUTH SHOULD SUFFICE.
PROGS ARE IN GOOD AGREEMENT BRINGING THE FRONT SOUTH INTO AT LEAST
NE LA OVERNIGHT AND INTO THE MORNING HOURS MONDAY. THE FRONT
SHOULD STALL ONCE AGAIN NEAR THE I-20 CORRIDOR FOR MONDAY BEFORE
WASHING OUT MONDAY NIGHT...BUT WILL STILL SERVE AS A DESCENT FOCUS
FOR HEAT DRIVEN CONVECTION ONCE AGAIN FOR MONDAY. CONCERNING THE
HEAT ADVISORY/EXCESSIVE HEAT WARNING...BELIEVE WE WILL AT LEAST
SEE SOME MIXING OUT OF THE DEWPOINT TEMPERATURES MONDAY AFTERNOON
ALONG AND NORTH OF THE FRONTAL BOUNDARY FOR MONDAY INTO TUESDAY.
SO WHILE WE CANNOT RULE OUT A FEW ISOLATED LOCATIONS SEEING HEAT
INDEX VALUES TOUCHING 110 DEGREES...ALONG AND SOUTH OF THE
BOUNDARY...FEEL LIKE EXCESSIVE HEAT CRITERIA WILL NOT BE MET. THE
HEAT ADVISORY MAY NEED TO BE EXTENDED FOR AT LEAST A PORTION OF
THE REGION FOR TUESDAY BUT WOULD PREFER TO SEE JUST WHERE THE
FRONTAL BOUNDARY STALLS BEFORE MAKING THIS CALL FOR TUESDAY.
BEYOND TUESDAY...WE SHIFT OUR FOCUS FRONT THE FRONTAL BOUNDARY TO
THE TROPICAL/HYBRID LOW PRESSURE SYSTEM SPINNING ACROSS SW GEORGIA
WHICH USED TO BE TROPICAL DEPRESSION #5. THE MODEL CONSENSUS IS
FOR THIS SYSTEM TO RE-ENTER THE NORTHERN GULF OF MEXICO AND TO
MOVE WESTWARD PARALLELING THE COAST AND COMING ONSHORE ONCE AGAIN
ACROSS SE LA BY LATE TUESDAY AND THEN TAKING UP A POSITION
SOMEWHERE BETWEEN ALEXANDRIA AND MCCOMB BY 12Z WED. BEYOND WED
AM...MODELS DIVERGE GREATLY AS TO THE SYSTEMS FORWARD SPEED AND
DIRECTION. PER HPC/TPC...WILL FOLLOW THEIR SOLUTION CLOSELY WHICH
TAKES THE SYSTEM NORTH AND EAST OF OUR REGION BY THU/12Z. IT MUST
BE NOTED THAT THIS SOLUTION (WHICH HAS THE SUPPORT OF MANY OF THE
ENSEMBLE MEMBERS) SIGNIFICANTLY DEVIATES FROM THE MUCH SLOWER GFS
AND THE QUICKER BUT EVEN FURTHER WEST ECMWF TRACK. NEEDLESS TO
SAY...CONFIDENCE IS VERY LOW BEYOND WEDNESDAY AS TO THE TRACK OF
THIS SYSTEM. BUT NONETHELESS...HAVE BEEFED UP POPS ACROSS OUR
EASTERN HALF FOR TUESDAY NIGHT THROUGH THURSDAY AND THIS MAY NOT
BE ENOUGH IF THE SLOWER/FURTHER WEST SOLUTION COMES TO FRUITION.
THE TRACK OF THE DISTURBANCE WILL OF COURSE EFFECT TEMPERATURES
THROUGH THE EXTENDED AS WELL SO FOR NOW...HAVE GONE A LITTLE
WARMER DURING THE MID WEEK TIME FRAME FOR TEMPERATURES ASSUMING A
FASTER...MORE NORTHERN TRACK OF THE LOW IS THE WAY TO GO.
OUR ENTIRE FORECAST (RAIN CHANCES AND TEMPERATURES) WILL HINGE ON
THE MOVEMENT OF THIS LOW NEXT WEEK. LETS HOPE THE TRACK WILL MAKE
A DENT ON THE EXCESSIVELY HOT TEMPERATURES AT THE VERY LEAST.
THANK YOU FOR COORDINATION EFFORTS...HPC...FWD...LZK...HGX AND
TSA.
PRELIMS TO FOLLOW...13.

.AVIATION...
WIDELY SCT CONVECTION HAS DEVELOPED ACROSS EXTREME NE TX/SE OK/SW
AR/NCNTRL LA...WITH ADDITIONAL REDEVELOPMENT POSSIBLE THROUGH THE
AFTERNOON AS AN ARRAY OF OUTFLOW BNDRYS CONTINUE TO PROPAGATE ACROSS
THESE AREAS. AM EXPECTING ADDITIONAL CONVECTION TO FIRE FARTHER N
ACROSS ERN OK/WRN AR THIS AFTERNOON...ALONG A WEAK SFC TROUGH
EXTENDING FROM CNTRL OK INTO NCNTRL AR. THIS CONVECTION COULD FOCUS
ADDITIONAL REDEVELOPMENT FARTHER S ACROSS SE OK/SW AR THROUGH EARLY
EVENING...POSSIBLY AFFECTING THE I-20 TERMINALS IN E TX/N LA AS THE
TROUGH BEGINS TO BACKDOOR SW INTO THE AREA. VFR CONDITIONS WILL
CONTINUE THROUGH MUCH OF THE TAF PERIOD...ASIDE FROM THE MVFR
CIGS/REDUCED VSBYS ASSOCIATED WITH THE CONVECTION. THESE SHOULD
DIMINISH BY 06Z...ALTHOUGH MID/HIGH LEVEL CONVECTIVE DEBRIS/CIGS ARE
EXPECTED TO DEVELOP AND SPREAD S AROUND THE UPPER RIDGE CENTER OVER
THE SRN PLAINS. THESE CIGS SHOULD THIN BY MIDDAY MONDAY...WITH
ADDITIONAL WIDELY SCT CONVECTION FIRING ONCE AGAIN ACROSS E
TX/NCNTRL LA IN VC OF THE SFC TROUGH DURING THE AFTERNOON. ISOLATED
CONVECTION WILL BE POSSIBLE FARTHER N AS DRIER AIR WILL LAG THE
TROUGH A WAYS. WSW WINDS 5-10KTS THIS AFTERNOON WILL BECOME LT/VRB
OR S 5KTS OR LESS AFTER 00Z. /15/
