AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
316 PM CDT TUE MAY 26 2009

.DISCUSSION...SHORT TERM(TONIGHT THROUGH THURSDAY NIGHT) BROAD UPPER
TROUGH REMAINS POSITIONED ACROSS THE LOWER MS VALLEY WITH AT LEAST
TWO MORE DISTINCT DISTURBANCES POISED TO CROSS OUR CWFA FOLLOWED BY A
COLD FRONT. A DEPARTING MID LEVEL VORT CENTER OVER THE TN VALLEY
PULLING AWAY TO THE NE BUT STILL PRODUCING SCATTERED SHRA/TSRA ACROSS
THE ERN QUARTER OF MS. MEANWHILE THE FIRST OF THE NEXT TWO VORT
TROUGHS CROSSING THE SABINE RIVER VALLEY AND HELPING TO SET OFF MORE
SCATTERED TSRA ALONG AND W OF THE MS RIVER WHERE DIURNAL HEATING HAS
BEEN AT A MAXIMUM WITH TEMPS APPROACHING 88F AND DEWPOINTS NEAR 70F.
THIS WEDGE OF THE MOST UNSTABLE AIR SHOULD MOVE EWD INTO WRN MS THIS
EVENING AND ALLOW ADDITIONAL TSRA TO FIRE OFF BEFORE SUNSET. 850MB
THETA E OF 335K AND MLCAPES OF 1500-2000J/KG WILL HELP FUEL THE
STORMS EVEN THOUGH MID LEVEL LAPSE RATES 5.5-6C. AS A RESULT...A FEW
OF THESE STORMS WILL BE STRONG WITH WIND GUSTS 40-45MPH AND LOCALIZED
DOWNPOURS OF 1 INCH IN LESS THAN ONE HOUR.

LATER TONIGHT...ISOLATED MOSTLY -SHRA SHOULD OCCUR MAINLY OVER SRN
THIRD OF CWFA. FOR WEDNESDAY...A LITTLE STRONGER HEATING WILL HELP IN
FIRING OFF ANOTHER DIURNAL ROUND OF MAINLY AFTERNOON TSRA AS A DEEPER
LAYER OF SWLY FLOW IN THE LOW AND MID LEVELS SHOULD PRODUCE FASTER
STORM MOTIONS. AIRMASS OF 850MB THETA E CLOSER TO 340K AND MLCAPES OF
2000J/KG WILL HELP FUEL THE STORMS WHICH SHOULD BE A LITTLE MORE
ROBUST THAN TODAY...ESPECIALLY IN THE NWRN PORTIONS OF THE CWFA. REFER
TO SPC DAY 2 CONVECTIVE OUTLOOK. THESE STORMS COULD PERSIST LONGER
INTO WEDNESDAY EVENING AS THE SECOND IN OUR MID LEVEL DISTURBANCES
MOVES THROUGH THE AREA.

THE FINAL ORGANIZER FOR TSRA DEVELOPMENT WILL COME ON THURSDAY WITH A
COLD FRONT DROPPING THROUGH THE NWRN CWFA BEFORE MIDDAY AND THEN THE
SERN QUARTER OF MS BY AFTERNOON. THE FASTER TIMING OF THIS FRONT
COMPARED TO PREVIOUS FORECAST CYCLE WILL GREATLY DETERMINE STORM
INTENSITY ON THURSDAY WHICH COULD BE MARGINALLY SEVERE IF THE FRONT
IS MATCHES UP WITH PEAK AFTERNOON HEATING. MID LEVEL FLOW OF 30-40KTS
WILL ALSO PLAY A ROLE IN GIVING THE STORMS A BOOST ON THURSDAY. DRIER
AIR WILL BE DROPPING IN BEHIND THE FRONT OVER OUR NWRN CWFA EARLY
THURSDAY EVENING AND THE FOLLOWING DAYS SHOULD BE GENERALLY DRY
STARTING WITH FRIDAY. OVERALL MAVE TEMPERATURE GUIDANCE LOOKS
REASONABLE WITH ONLY VERY MINOR ADJUSTMENTS./40/

REST OF THE PREVIOUS DISCUSSION HEADING INTO THE WEEKEND...HIGH
PRESSURE SETTLES OVER THE AREA SATURDAY AND KEEPS THE REGION DRY
THROUGH EARLY NEXT WEEK. THE GFS REMAINS A LITTLE FASTER IN THE EURO
WITH BRINGING THE RAIN BACK INTO THE AREA. STILL THINKING IT WILL BE
TUESDAY BEFORE SHOWERS MOVE BACK INTO THE CWA. ADJUSTED THE POPS DOWN
SLIGHTLY FOR MONDAY AND KEPT THE BEST RAIN CHANCES MONDAY AFTERNOON
INTO THE EVENING. THE WET PATTERN RETURNS FOR NEXT WEEK. A COLD FRONT
DROPS INTO THE AREA AROUND WEDNESDAY. THE CWA WILL BACK INTO THE WARM
SECTOR...WITH PLENTY OF WARM AND MOIST AIR AVAILABLE. A SURFACE LOW
TRACKS ALONG THE BOUNDARY INTO THE CWA INCREASING RAIN CHANCES FOR
MUCH OF NEXT WEEK.

TEMPERATURES AND POPS WERE GOOD THROUGH THE WEEK...SO STUCK WITH
GUIDANCE. WILL LEAVE THE HWO CLEAR FOR THE EXTENDED./07/

&&

.AVIATION...SKY CONDITIONS WILL VARY THROUGH THE LATE AFTERNOON AND
EVENING HOURS. GENERALLY VFR CONDITIONS WITH CEILINGS ABOVE 3000 FT.
SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON WILL TRACK EAST
ACROSS THE REGION. IFR CONDITIONS WILL PREVAIL IN LOCAL DOWNPOURS...
MAINLY W PORTIONS. EXPECT ISOLATED ACTIVITY TO CONTINUE THROUGH THE
OVERNIGHT HOURS INTO WEDNESDAY MORNING. IFR-MVFR STRATUS CEILINGS
WILL PREVAIL PRIOR TO DAWN THROUGH WEDNESDAY MORNING. SOME LIGHT TO
MODERATE FOG WILL DEVELOP AFTER MIDNIGHT THROUGH MID MORNING
WEDNESDAY. MVFR CEILINGS SHOULD RESUME 15-17Z. /17/
