Damaging Wind in Mississippi, August 1, 2006

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
219 PM CDT TUE AUG 1 2006

.SHORT TERM...SCT CONVECTION ACROSS CNTRL AND SRN MS DEVELOPED THIS
AFTERNOON WITH A FEW STORMS REACHING STRONG TO SEVERE LIMITS. THIS
ACTIVITY WILL BEGIN TO DECREASE SHORTLY AFTER SUNSET AS WE LOSE THE
HEATING OF THE DAY AND INSTABILITY DECREASES. A FEW STORMS MAY LAST
INTO THE MID EVENING HOURS AS THE DISTURBANCE ALOFT CONTINUES TO
MOVE WEST THROUGH THE CWA. CLOUDS WILL START TO CLEAR OUT AFTER THAT
AND SKIES SHOULD BE CLEAR BY 06Z. LOWS TONIGHT WILL DROP INTO THE
LOWER TO MID 70S.

TOMORROW THERE WILL BE LESS CONVECTION TO WORRY ABOUT AS DRIER AIR
BEGINS TO FILTER IN FROM THE WEST. UPPER RIDGE WILL FINALLY BEGIN TO
FLATTEN OVER THE AREA WHILE THE SFC RIDGE AXIS FROM THE BERMUDA HIGH
REMAINS OVER THE NRN GOM. STILL EXPECT SOME ISLTD TO POSSIBLY SCT
ACTIVITY ACROSS THE EAST BUT THE COVERAGE WILL BE FAR LESS THAN THIS
AFTERNOON. NOT EXPECTING ANY STRONG TSRA AS LAPSE RATES WILL BE MUCH
WEAKER THAN TODAYS WITH MID LEVEL TEMPS RISING(H5 -4C). THE EAST
WILL BE IN THE RRQ OF A WEAK UPPER JET AND THIS WILL BE WHAT HELPS
TO FOCUS CONVECTION IN THAT AREA. HIGHS WILL ALSO BE A LITTLE WARMER
DUE TO WARMING LL TEMPS AND LESS CLOUD COVER TO WORRY ABOUT. WITH
H85 TEMPS APPROACHING 20C MANY LOCATIONS EAST OF I 55 WILL EASILY
GET INTO THE MID 90S AND PLACES IN THE DELTA COULD APPROACH THE
UPPER 90S. EAST OF I 55 HIGHS WILL BE IN THE LOWER TO MID 90S AS
CLOUD COVER WILL BE A LITTLE GREATER IN THAT AREA. MAV GUI AGREES
WITH THIS THINKING SO I WILL NOT DEVIATE. CONVECTION WILL QUICKLY
COME TO AN END AFTER SUNSET TOMORROW NIGHT AND SKIES SHOULD BE
MOSTLY CLEAR BY 03Z. LOWS WILL ONCE AGAIN DROP INTO THE LOWER TO MID
70S. /CAB/

.LONG TERM...VERY FEW CHANGES MADE TO THE EXTENDED FORECAST. LONG RANGE
MODELS AGREE ON KEEPING UPPER LEVEL RIDGING THE PREDOMINANT INFLUENCE
IN THE DEEP SOUTH THROUGH THE MIDDLE OF NEXT WEEK. THIS WILL ENSURE
ABOVE NORMAL HEAT CONTINUES WITH RAIN CHANCES PROBABLY A BIT BELOW
CLIMATOLOGY ON AVERAGE.

HIGH TEMPERATURES FROM THURSDAY THROUGH NEXT TUESDAY WILL AVERAGE IN
THE MID 90S WITH QUITE A FEW SPOTS EXPERIENCING UPPER 90S FOR A FEW
DAYS. ANOTHER BOUT OF 99-103 NOT COMPLETELY OUT OF THE QUESTION
AT THIS POINT ALONG AND NORTH OF I-20. FORTUNATELY...HEAT ADVISORIES
ARE NOT ANTICIPATED THROUGH THE END OF THE WORK WEEK AS DRIER AIR IN
THE MID LEVELS SHOULD MAKE A DENT IN TROPICAL SURFACE MOISTURE
DURING THE HEAT OF THE DAY.

ALTHOUGH THE LONG RANGE FORECAST LOOKS PRETTY DRY AS A
WHOLE...SATURDAY AND SUNDAY MAY HOLD A LITTLE MORE PROMISE FOR
PRECIPITATION. DURING THOSE DAYS AN UPPER TROPICAL DISTURBANCE WILL
MOVE BY IN THE EASTERLIES WHILE A SURFACE FRONTS TRIES TO DROP DOWN
FROM THE NORTH IN THE PROCESS OF WASHING OUT. BOTH THESE FEATURES
HAVE TO BATTLE WITH STRONG IN SITU RIDGING OVERHEAD...SO LOTS OF
SHOWERS AND STORMS IS BY NO MEANS A DONE DEAL.

ANOTHER EXTREMELY SMALL WRINKLE IN THE FORECAST IS THE QUESTION MARK
OF CURRENT TS CHRIS...WAY OUT IN THE ATLANTIC. FORECAST STEERING
CURRENTS MAY STEER THE SYSTEM IN OUR GENERAL DIRECTION BY THE MIDDLE
OF NEXT WEEK...IF IT HOLDS TOGETHER. THAT IS A BIG IF RIGHT
NOW...SO DEFINITELY NOT ANYTHING TO GET EXCITED ABOUT YET.

AS FOR STATS...I REMAINED NEAR PREVIOUS FORECASTERS NUMBERS...WHICH
WHERE CLOSE TO 00Z MEX. I DID STRAY A TOUCH HIGHER THAN MEX ON HIGH
TEMPS THROUGH THE PERIOD THOUGH...FEELING JUSTIFIED BY PERSISTENCE
AND MODEL ENSEMBLE AVERAGES. ALSO CUT POPS BACK 10 PERCENT OR SO
TOWARD THE END OF THE LONG TERM AS GUIDANCE SEEMS TO RELY ON CLIMO
IN MIDST OF MAJOR HEIGHT RISES. /BB/
