AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
946 PM CDT MON AUG 10 2015
.UPDATE...THE FORECAST WAS UPDATED EARLIER THIS EVENING TO EXPIRE THE
EXCESSIVE HEAT WARNING AND LOWER POPS IN THE SOUTH AS THE CONVECTION
HAS ENDED THERE FOR THE NIGHT. A HEAT ADVISORY REMAINS IN EFFECT
SOUTH OF HIGHWAY 82 THROUGH TUESDAY AS HEAT INDEX VALUES ARE STILL
EXPECTED TO PEAK BETWEEN 105 AND 110. SOME RELIEF TO THE RECENT
OPPRESSIVE HEAT LOOKS TO BE ON THE WAY THOUGH. CURRENTLY RADARS WERE
INDICATING ADDITIONAL CONVECTION OVER OUR NORTHEAST ZONES. THIS
ACTIVITY WAS ALONG A VERY SLOW MOVING COLD FRONT THAT WILL CONTINUE
TO SAG SOUTH THROUGH TUESDAY. GREATEST RAIN CHANCES WITH THE FRONT
AREA EXPECTED OVER EAST MISSISSIPPI TONIGHT. THE DRIER AIR IN THE
WAKE OF THE FRONT WILL BRING LOWER HUMIDITY AND HEAT INDICES. THE
RAINFALL EARLIER THIS EVENING IN THE SOUTH COOLED TEMPERATURES A
LITTLE FASTER THAN EXPECTED BUT MORNING LOWS WERE STILL ON TRACK.

DUE TO +RA AND GUSTY WINDS ARE POSSIBLE WITH THE STORMS. OTHERWISE...

.PREV DISCUSSION... /ISSUED 330 PM CDT AUG 10 2015/
SHORT TERM(TONIGHT THROUGH WEDNESDAY NIGHT)...LATEST SATELLITE
IMAGERY SHOWED THE REGION UNDER THE MEAN RIDGE CENTERED OVER THE
ARKLATEX REGION. A MORNING MCS HAD SENT A OUTFLOW BOUNDARY ACROSS
THE NORTH. A FRONTAL BOUNDARY WAS PUSHING TOWARD THE REGION FROM THE
CENTRAL MISSISSIPPI VALLEY. AREA RADARS WERE PICKING UP SOME
ISOLATED CONVECTION ACROSS THE REGION. TEMPS AS OF MID AFTERNOON
RANGED FROM THE LOWER 90S TO AROUND 100 DEGREES. A WELCOME PATTERN
CHANGE IS COMING FOR THE REST OF THE WORK WEEK AS THE MEAN RIDGE
CENTER WILL BE PUSHED INTO THE SOUTHERN PLAINS AND ROCKIES...WHILE
AN UPPER TROUGH DEVELOPS OVER THE EASTERN US. FOR THE REST OF THE
AFTERNOON EXPECT THE CONVECTION TO INCREASE TO SCATTERED COVERAGE
OVER SOME OF THE CWA. WITH CURRENT TRENDS SOME LOCATIONS MAY NOT
REACH EXCESSIVE HEAT WARNING CRITERIA...BUT HAVE OPTED TO LET THAT
WARNING EXPIRE AT 7 PM. FOR TONIGHT THE FRONTAL BOUNDARY WILL START
TO MOVE OVER THE REGION. THIS WILL ALLOW OUR RAIN CHANCES TO
CONTINUE OVERNIGHT...ESPECIALLY IN THE EASTERN PORTIONS OF THE CWA.
IT WILL BE ANOTHER HUMID NIGHT WITH LOWS IN THE MID TO UPPER 70S.
FOR TUESDAY THE FRONT WILL MAKE ITS WAY TOWARD THE SOUTHERN PORTION
OF THE REGION. THERE MAY BE A MARGINAL RISK OF SOME SEVERE IN THE
SOUTH HALF...BUT THERE ARE SOME ISSUES WITH THAT. IT WILL DEPEND ON
THE WHAT HAPPENS THIS AFTERNOON INTO THE OVERNIGHT HOURS CONVECTION
WISE. I COULD SEE SOME MORNING ACTIVITY AFFECTING AIR MASS RECOVERY.
SO WITH THAT IN MIND WILL LET THE MID SHIFT TAKE ANOTHER LOOK AT
THAT. IT WILL BE ANOTHER WARM DAY FOR TUESDAY WITH HIGHS FROM THE
MIDDLE TO UPPER 90S. HEAT INDICES WILL BE FROM 106 TO 110 FOR A HEAT
ADVISORY EXTENDING OVER MOST OF THE REGION. INDICES NORTH OF THE
ADVISORY AREA WILL BE AT 105. FOR TUESDAY NIGHT OUR CHANCES OF RAIN
WILL PUSH SOUTH. SOME SLIGHTLY DRIER AIR WILL PUSH INTO OUR NORTHERN
COUNTIES AS WE GET SOME 60S DEWPOINTS COMING IN. THIS WILL SEND
READINGS DOWN INTO THE LOWER 70S NORTH TO THE MIDDLE 70S SOUTH. AS
WE PUSH INTO WEDNESDAY THE FRONTAL BOUNDARY WILL BE SOUTH OF THE
REGION AND IT WILL TAKE THE LAST CHANCE OF RAIN IN THE PINEBELT AREA
WITH IT. BEHIND THE FRONT TEMPS WILL MODERATE SOME WITH HIGHS IN THE
90-94 RANGE. THE 60S DEWPOINTS WILL SPREAD ACROSS THE REST OF THE
CWA...MAKING FOR LESS HUMID CONDITIONS. FOR WEDNESDAY NIGHT SLIGHTLY
COOLER TEMPS WILL BE ACROSS THE ARKLAMISS WITH LOWS IN THE MIDDLE
60S NORTHEAST TO THE LOWER 70S SOUTHWEST. THE MIDDLE 60S WILL BE
AROUND FIVE DEGREES LOWER THAN SEASONAL READINGS./17/
LONG TERM...(THURSDAY THROUGH NEXT MONDAY)...NOT SEEING MUCH IN THE
WAY OF NEEDED RAINFALL FOR THE PERIOD. THE FORECAST AREA WILL BECOME
FIXED BETWEEN AN UPPER TROUGH OVER THE EAST COAST OF THE UNITED
STATES AND THE STUBBORN UPPER RIDGE CENTERED NEAR THE FOUR CORNERS
REGION. NORTHERLY FLOW ALOFT AND AT THE SURFACE THROUGH MUCH OF THE
WEEK WILL ADVECT DRIER AIR INTO THE REGION. PWATS WILL GO DOWN TO
AROUND 0.75 INCH ON THURSDAY INTO FRIDAY...BEFORE RISING TO AROUND
1.8 INCHES BY MONDAY NIGHT. WHILE HIGHS TOP OUT IN THE LOW TO MIDDLE
90S...THE NOTICEABLY DRIER AIR WILL HELP TO MAKE FOR MORE TOLERABLE
CONDITIONS EACH AFTERNOON...AS WELL AS OVERNIGHT AS LOWS FALL INTO
THE 60S AND 70S. AS EXPECTED THOUGH...DEW POINTS WILL MODERATE UP
SLIGHTLY OVER THE WEEKEND...AND THE CHANCES OF AT LEAST SOME
ISOLATED TO SCATTERED CONVECTION RETURNING TO THE FORECAST SATURDAY
THROUGH MONDAY. 17/19/
