AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
328 PM CDT SAT MAY 16 2009

.DISCUSSION...TONIGHT THROUGH SUNDAY NIGHT...WITH AN ALREADY
WARM...VERY MOIST...AND UNSTABLE AIRMASS IN PLACE ACROSS THE REGION
THIS AFTERNOON...COUPLED WITH AN OUTFLOW BOUNDARY DROPPING SOUTHEAST
THROUGH THE AREA AND A COLD FRONT TRAILING IN ITS WAKE...CONVECTION
IS ONGOING ACROSS THE FORECAST AREA AND WILL CONTINUE INTO THE
EVENING HOURS.  SOME OF THESE STORMS HAVE BEEN ON THE STRONG TO
SEVERE SIDE THIS AFTERNOON...AND AGAIN THIS WILL CONTINUE TO BE THE
CASE DURING THE EVENING WITH HAIL AND GUSTY WINDS BEING THE MAIN
CONCERNS WITH THESE STORMS. ALSO...WITH SUCH A SOUPY AIRMASS IN
PLACE...HEAVY RAIN WILL BE POSSIBLE WITH THIS ACTIVITY AND COULD
RESULT IN SOME LOCALIZED FLASH FLOODING.

THE BETTER RAIN CHANCES WILL REMAIN ACROSS CENTRAL AND SOUTHERN
PORTIONS OF THE FORECAST AREA THROUGH THE OVERNIGHT HOURS TONIGHT AS
THE FRONT CONTINUES ITS SOUTHEASTWARD TREK.  BEHIND THE
FRONT...HIGH PRESSURE WILL BEGIN TO BUILD INTO THE AREA WITH SOME
SLIGHTLY DRIER AIR FILTERING SOUTHWARD INTO THE AREA.

SOME SMALL RAIN CHANCES WILL LINGER ACROSS THE AREA THROUGH THE DAY
SUNDAY AS THE UPPER TROUGH CONTINUES TO SWING EAST ACROSS THE
REGION.  BY SUNDAY NIGHT THOUGH...RAIN SHOULD COME TO AN END ACROSS
THE ENTIRE FORECAST AREA AND SKIES WILL BEGIN TO CLEAR.  HIGH
PRESSURE DURING THIS TIME WILL CONTINUE TO BUILD DEEPER INTO THE
REGION WHILE FILTERING IN A COOLER DRIER AIRMASS.  AS A
RESULT...LOOK FOR THERE TO BE AN ALMOST FALL-LIKE FEEL TO THE AIR
SUNDAY NIGHT INTO EARLY MONDAY MORNING AS TEMPERATURES COOL INTO THE
MID 40S AND LOWER 50S.

THE PREVIOUS LONG TERM DISCUSSION FOLLOWS FOR THE REMAINDER OF THE
FORECAST PERIOD. /19/

MONDAY THROUGH FRIDAY...SURFACE HIGH WILL SLIDE INTO THE OHIO VALLEY
MONDAY. THIS SYSTEM WILL GIVE US SOME DRIER/MUCH COOLER AIR FOR THE
FIRST FEW DAYS OF NEXT WEEK AS IT MOVES EAST. 850MB TEMPS WILL BE
DOWN TO AT LEAST 10C OR SLIGHTLY COOLER. THESE VALUES WOULD TRANSLATE
TO LOWS 48-55F AND HIGHS 71-78F FOR MONDAY. TEMPS WILL SPILL INTO THE
LOWER 80S AS WE GET INTO TUESDAY WITH LOWS IN THE 50S. THIS WILL
OCCUR AS AN UPPER RIDGE BUILDS TOWARD THE REGION FROM THE SOUTHERN
PLAINS. THEN TEMPS WILL PUSH TOWARD THE MIDDLE 80S BY WEDNESDAY WITH
LOWS IN THE UPPER 50S TO LOWER 60S BY THURSDAY MORNING.

GFS CONTINUES TO DEVELOP A NEARLY VERTICALLY STACKED CIRCULATION IN
THE EASTERN GULF ON WEDNESDAY. THIS FEATURE WILL PUSH WESTWARD
TO THE LOUISIANA AND MISSISSIPPI COASTAL REGION ON THURSDAY...WHILE
THIS FEATURE PUSHES WERE IN THE CENTRAL GULF AT THIS TIME ON THE
EUROPEAN. THE EUROPEAN MODEL THEN PUSHES IT TOWARD THE NORTHEAST
GULF COAST ON FRIDAY. THE GFS KEEPS THE UPPER LOW AROUND THE COASTAL
REGION THROUGH FRIDAY. THE GFS KEEPS THE INFLUENCE OF THE UPPER LOW
AROUND THE ARKLAMISS REGION THROUGH MEMORIAL DAY WEEKEND. THE
EUROPEAN MODEL FINALLY BRINGS THIS FEATURE INTO THE REGION AFTER
MEMORIAL DAY WEEKEND.

THE NET RESULT WILL BE SEVERAL DAYS OF NELY FLOW IN THE LOW LEVELS
FOR OUR REGION WITH OVERNIGHT LOWS IN THE 50S THROUGH THE MIDDLE OF
THE WEEK. WE WILL START TO GET SOME CHANCES OF CONVECTION FOR
THURSDAY THROUGH FRIDAY AS WE START TO FEEL THE INFLUENCE OF THE
UPPER LOW COMING FROM THE EAST.

AS FAR AS TEMPS ARE CONCERN WENT CLOSE TO MOS AND HPC GUIDANCE.
THE COOLEST DAYTIME HIGHS WILL BE ON MONDAY WITH HIGHS IN THE 70S.
THE COOLEST NIGHT WILL BE MONDAY NIGHT WITH LOWS IN THE UPPER 40S TO
MIDDLE 50S.  RECORD LOWS FOR EARLY NEXT WEEK ARE GENERALLY IN THE
MIDDLE 40S. THE COOL AIR WILL NOT LAST TOO LONG. PLENTY OF DAILY SUN
WILL HELP MODIFY THE AIR MASS TO BRING BACK NEAR NORMAL HIGH
TEMPERATURES TO THE ARKLAMISS REGION FOR WEDNESDAY THROUGH
FRIDAY. /17/

&&

.AVIATION...WIDESPREAD MVFR CIGS BKN-OVC FROM 2-4K FEET CAN BE
EXPECTED THIS EVENING WITH NUMEROUS SHOWERS AND THUNDERSTORMS ACROSS
THE FORECAST AREA. WILL BRIEFLY SEE LOWER CIGS/VSBY FLIGHT
CATEGORIES IN PERIODS OF HEAVIER RAINFALL. THUNDERSTORMS WILL END IN
THE WAKE OF THE COLD FRONT AS IT TRACKS SLOWLY SWD ACROSS THE REGION
TONIGHT BUT MVFR CIGS AND OCCASIONAL SHOWERS WILL CONTINUE BEHIND
THE COLD FRONT TONIGHT. THE FRONT WILL MOVE NEAR THE I-20 CORRIDOR
AROUND 10 PM AND MAY STALL IN THE VICINITY OF HIGHWAY 84 AFTER
MIDNIGHT. DRIER AIR WILL PUSH INTO THE AREA SUNDAY FOR DRIER
CONDITIONS AND GUSTY NORTHWEST WIND. /03/
