AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
440 PM CDT FRI JUN 12 2009

...SEVERE THUNDERSTORMS POSSIBLE ACROSS THE HIGHWAY 82 CORRIDOR THIS
AFTERNOON AND EVENING...

.SHORT TERM...TONIGHT THROUGH SUNDAY...A LARGE BOWING COMPLEX OF
THUNDERSTORMS WAS NOTED MOVING INTO NORTHWEST MISSISSIPPI WITH
SCATTERED THUNDERSTORMS AHEAD OF THE COMPLEX JUST NORTH OF HIGHWAY
82. A FEW OF THE SCATTERED THUNDERSTORMS MAY BECOME SEVERE BUT A
MORE WIDESPREAD THREAT OF DAMAGING WINDS AND LARGE HAIL IS EXPECTED
ALONG AND NORTH OF THE HIGHWAY 82 CORRIDOR AS THE COMPLEX OF
THUNDERSTORMS MARCHES EAST SOUTHEAST THIS AFTERNOON AND EVENING.
OUTFLOW BOUNDARIES FROM THE COMPLEX MAY TRIGGER SHOWERS AND
THUNDERSTORMS AS FAR SOUTH AS THE INTERSTATE 20 CORRIDOR THIS
EVENING BUT STUBBORN HIGH PRESSURE TO OUR SOUTH HAS SUPPRESSED
CONVECTION AGAIN TODAY. THE COMPLEX IS EXPECTED TO DISSIPATE AND/OR
SHIFT EAST OF OUR CWFA BY MIDNIGHT BUT IT WILL LIKELY LEAVE A
BOUNDARY ACROSS OUR NORTHERN COUNTIES THAT WILL SERVE AS A FOCUS FOR
CONVECTION SATURDAY. THE SURFACE HIGH OVER THE NORTHERN GULF WILL
REMAIN IN PLACE SATURDAY WHILE THE MID LEVEL HIGH OVER MEXICO AND
SOUTHERN TEXAS RIDGES BACK TO THE NORTHEAST INTO OUR REGION. THIS
WILL LIKELY SUPPRESS CONVECTION AND LIMIT RAIN CHANCES ACROSS THE
SOUTHERN HALF OF OUR AREA SATURDAY WHILE PULSE SEVERE STORMS WILL BE
POSSIBLE IN THE NORTH IN THE VICINITY OF THE BOUNDARY DURING THE
HEAT OF THE DAY. WL MENTION THIS POTENTIAL IN THE HWO. AFTER ANOTHER
WARMER THAN NORMAL NIGHT TONIGHT... TEMPERATURES WILL BE WARM AGAIN
SATURDAY AND TOP OUT IN THE LOWER 90S. AFTERNOON HIGHS WILL BE A
DEGREE OR TWO WARMER ON SUNDAY. THERE WAS VERY LITTLE SPREAD IN
GUIDANCE TEMPS THROUGH THE SHORT TERM AND MAV TEMPS WERE GENERALLY
ACCEPTED. HIGH PRESSURE SURFACE AND ALOFT WILL DOMINATE THE SOUTHERN
HALF OF OUR AREA THROUGH SUNDAY WHILE LINGERING BOUNDARIES AND OUR
WARM MOIST UNSTABLE AIRMASS WILL RESULT IN RAIN CHANCES BEING
CARRIED IN THE NORTH. /22/

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...THE WEATHER STORY IN THE
EXTENDED CONTINUES TO BE THE EFFECT OF WEAK TRANSIENT WAVES ON A
STRONG UPPER RIDGE THAT WILL BE PARKED OVER THE AREA. MODELS AGREE
THAT WEAK WAVES WILL OCCASIONALLY LIFT OVER THE NRN EDGES OF UPPER
RIDGING OVER THE ARKLAMISS REGION TO MAINTAIN A SLIGHT CHANCE OF
CONVECTION...MAINLY OVER NRN ZONES. THE MORE PRONOUNCED LOW LEVEL
TROUGHING IS FORECAST TO REMAIN WELL N OF THE FORECAST AREA ALTHOUGH
THE EURO REMAINS CONSISTENT IN MAINTAINING WEAK SURFACE CONVERGENCE
AS IT PARKS THE REMNANTS OF A BOUNDARY ACROSS THE AREA. WITH 500 MB
HEIGHTS AT OR ABOVE 588 DAM AND GENERALLY ANTICYCLONIC FLOW AT 850
MB WE WILL HAVE SIGNIFICANT SUBSIDENCE TO OVERCOME. ALTHOUGH THE
EURO POSTS THE STRONGEST RIDGING OVER THE REGION THROUGH THE
EXTENDED...THE GFS SHIFTS THE RIDGE CENTER SLIGHTLY WWD BY MID WEEK
TO SUGGEST A BETTER CHANCE OF ISOLATED CONVECTION. IF THE GFS
SOLUTION OCCURS THEN THE DOOR WILL OPEN FOR ANOTHER WEAK IMPULSE TO
DROP THIS WAY TO HELP IN CONVECTION DURING AFTERNOON HEATING. WILL
FOLLOW AVERAGE GFS ENSEMBLE MEMBERS FOR NOW AND LEAVE SLIGHT CHANCE
OF PCPN OVER ERN AND SRN ZONES FOR WED. GENERALLY FOLLOWED MOS
TEMPERATURES THROUGH THE EXTENDED...THE EXCEPTION ONCE AGAIN BEING
AFTERNOON HIGHS WHEN MOS APPEARS TO BE HITTING MID 90S A BIT TOO
FAST AND WIDESPREAD. LEFT MID 90S FOR MONDAY AND TUESDAY WHEN MODEL
CONSENSUS IS FOR STRONGEST RIDGING. WILL SEE ANOTHER DAY OF MID 90S
FOR WEDNESDAY IF THE EURO PANS OUT AND THE GFS SOLUTION OF SHIFTING
THE RIDGE CENTER DOES NOT WORK OUT. /03/

&&

.AVIATION...A LARGE BOWING COMPLEX OF THUNDERSTORMS OVER SOUTHEAST
ARKANSAS WILL MOVE TO THE EAST SOUTHEAST ACROSS THE HIGHWAY 82
CORRIDOR AND AFFECT TAF SITES FROM GLH-GWO-GTR THIS EVENING. WINDS
IN EXCESS OF 50KTS...LARGE HAIL AND FREQUENT LIGHTNING WILL BE
POSSIBLE WITH THESE STORMS. AFTER THE STORMS DISSIPATE OR SHIFT EAST
OF THE AREA...VFR CONDITIONS WILL PREVAIL UNTIL AFTER 09Z. IN AREAS
THAT RECEIVE RAIN IFR/LIFR VISIBILITIES MAY DEVELOP BETWEEN 09Z AND
13Z. OTHERWISE MVFR VISIBILITIES WILL BE POSSIBLE IN THE REMAINDER
OF THE AREA. THE FOG WILL QUICKLY DISSIPATE SATURDAY MORNING AND VFR
CONDITIONS ARE EXPECTED BY 14Z. ISOLATED CONVECTION WILL BE POSSIBLE
ACROSS THE NORTH AGAIN SATURDAY AFTERNOON. /17/
