NATIONAL WEATHER SERVICE SHREVEPORT LA
315 AM CDT WED JUN 24 2009
.DISCUSSION...
EXCESSIVE HEAT WILL CONTINUE TODAY WITH HEAT INDEX VALUES
EXPECTED TO MEET OR EXCEED 105 DEGREES TODAY ACROSS MOST AREAS.
SEEING THAT WE SAW THOSE CONDITIONS ON TUESDAY AND EXPECTING
SIMILAR CONDITIONS TODAY...HAVE POSTED A HEAT ADVISORY FOR OUR
ENTIRE AREA VALID THROUGH 00Z.
CONVECTION DEVELOPED TUESDAY AFTERNOON ACROSS CENTRAL ARKANSAS AND
SPREAD SOUTHWARD ALONG THE BACK SIDE OF OUR UPPER RIDGE WITH A
REMNANT OUTFLOW BOUNDARY LIKELY IN THE VICINITY OF DEEP EAST TEXAS
INTO CENTRAL LOUISIANA THIS MORNING. THIS COMBINED WITH FAVORABLE
SHEAR AXIS EXPECTED TO RESIDE ACROSS NE TX/SE OK TODAY...HAVE GONE
WITH SLIGHT CHANCE POPS AREAWIDE INTO THE EVENING HOURS. CONVECTION
ACROSS N MISS THIS MORNING AS WELL LIKELY IN ASSOCIATION WITH WEAK
VORTICITY AND A WEAK BACKDOOR FRONTAL BOUNDARY WHICH SHOULD MAKE
GOOD PROGRESS INTO OUR NE ZONES THIS AFTERNOON. ANY CONVECTION
THAT DEVELOPS GIVEN THE AFTERNOON TEMPERATURES COULD EASILY
PRODUCE STRONG AND DAMAGING WIND GUSTS SO WILL MENTION THIS
POSSIBILITY AS WELL IN MORNING HWO.
NOT CONFIDENT ON JUST HOW FAR WEST THE BACKDOOR BOUNDARY WILL MOVE
TONIGHT INTO THURSDAY BUT THE BOUNDARY COULD ACT TO LOWER
DEWPOINTS ENOUGH SUCH THAT HEAT INDEX VALUES MAY NOT REACH
ADVISORY CRITERIA ON THURSDAY. WILL LET FUTURE SHIFTS MAKE THIS
CALL ON WHETHER OR NOT TO EXPAND THE ADVISORY INTO THURSDAY.
FOR THE WEEKEND INTO NEXT WEEK...FOLLOWED THE ECMWF CLOSELY WITH ITS
HANDLING OF THE UPPER LEVEL RIDGE AXIS. THE RIDGE SHOULD BE SUPPRESSED
ENOUGH TO OUR NORTH AND WEST FOR INCREASING CONVECTIVE POSSIBILITIES
FOR LATE SUNDAY INTO NEXT WEEK. UPPER FLOW COULD BECOME NORTHWEST
ENOUGH SUCH THAT MEDIUM RANGE PROGS ARE IN AGREEMENT WITH ANOTHER
COOL FRONT PUSHING INTO THE REGION EARLY NEXT WEEK. THUS...KEPT
SLIGHT CHANCE POPS GOING THROUGH NEXT WEEK AS WELL.
MANY THANKS TO OUR SURROUNDING OFFICES FOR COORDINATION THIS MORNING...
