AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
353 PM CDT MON JUN 1 2009

.SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT...ANOTHER WARM DAY IS
UNDERWAY ACROSS THE AREA AS READINGS HAVE QUICKLY WARMED INTO THE
LOWER 90S FOR THE SECOND STRAIGHT DAY. THERE HAS BEEN A LITTLE MORE
CLOUD COVER TODAY WITH THE INCREASE IN MOISTURE ACROSS THE AREA.
THIS IS ALSO INDICATED ON THIS MORNINGS SOUNDING WITH PWATS NOW OVER
AN INCH AND LIGHT SOUTHERLY WINDS BRINGING IN THAT MOISTURE.

FOR TONIGHT AND TUESDAY NIGHT...CONDITIONS WILL CONTINUE TO BE DRY AS
HIGH PRESSURE REMAINS OVER THE AREA. WARM CONDITIONS WILL CONTINUE
AS MOISTURE FEEDS INTO THE REGION. TUESDAY WILL AGAIN BE ON THE WARM
SIDE...THOUGH NOT QUITE AS WARM GIVEN INCREASED CLOUD COVER AND
DEWPOINTS ACROSS THE REGION. THE GFS CONTINUES TO INDICATE A LOW
MOVING ACROSS THE GULF AND THIS WOULD ALLOW FOR THE POSSIBILITY OF
SOME AFTERNOON STORMS MAINLY IN THE SOUTH. WHILE THE EURO AND NAM
ARE NOT INDICATING THIS FEATURE...THEY ARE INDICATING SOME POSSIBLE
DIURNAL SHOWERS AND HAVE LEFT SLIGHT CHANCE POPS IN THE FAR SOUTH.
RAIN CHANCES LOOK TO DIMINISH DURING THE EVENING AND OVERNIGHT LOWS
WILL ONCE AGAIN BE ON THE WARM SIDE.

UPPER RIDGE BREAKS DOWN BY WEDNESDAY AS A COLD FRONT APPROACHES THE
REGION. THE 12Z GFS RUN CAME IN A LITTLE FASTER WITH THE FRONT BUT
KEPT THE HIGHEST POPS IN FOR WEDNESDAY INTO WEDNESDAY NIGHT. WITH
AMPLE MOISTURE ACROSS THE AREA(PWATS NEARING 2 INCHES)...MLCAPES OF
AROUND 1500-2000J/KG...DECENT LAPSE RATES AND 850MB THETA E OF
335-340K...AS WELL AS 30-35KT MID LEVEL FLOW...IT LOOKS POSSIBLE FOR SOME
STRONG TO SEVERE STORMS WITH THIS FRONT. MAIN RISK LOOKS TO COME FROM
WINDS AND POSSIBLY HAIL. HEAVY RAIN WILL ALSO BE A CONCERN. FRONT
LOOKS TO BE THROUGH BY THURSDAY MORNING.

AS FOR THE FORECAST...GUI TEMPS CAME IN GOOD. LOWS ON WEDNESDAY
LOOKED A LITTLE LOW. EVEN THOUGH FRONT WILL BE FASTER...STILL
THOUGHT TEMPS WERE A LITTLE LOW AND LIKELY WONT FEEL THE COOLER AIR
THAT QUICKLY. HIGHS WERE GOOD AND MADE MINOR ADJUSTMENTS FOR
WEDNESDAY AS AREA SHOULD WARM UP AHEAD OF THE FRONT. ADJUSTED POPS
FOR WED. INTO WED. NIGHT FOR FRONTAL PASSAGE....ESPECIALLY ACROSS
THE NORTH AS GUIDANCE SEEMED TO COME IN A LITTLE LOW. IN
ADDITION...WITH THE FASTER FROPA I ALSO ADJUSTED POPS ON THURSDAY
FOR LOCATIONS MAINLY ALONG AND NORTHWEST OF THE NATCHEZ TRACE AS
BULK OF PRECIP LOOKS TO BE OUT OF THE AREA. I ESPECIALLY LOWERED IN
THE WEST WHERE RAIN SHOULD HAVE TAPERED OFF THE MOST. /28/

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY NIGHT...DRIER AIR SHOULD BEGIN
SURGING BACK IN FROM THE OZARKS THURSDAY NIGHT INTO FRIDAY SETTING UP
ANOTHER DRY WEEKEND WITH PLEASANT OVERNIGHTS AND WARM AFTERNOONS. THE
PWATS BEGIN DROPPING BACK TO 1.2 INCHES THURSDAY NIGHT AND NWLY FLOW
ALOFT DRIVES PWATS DROPPING TO NEAR 1 INCH FRIDAY AND SATURDAY
HELPING TO KEEP THOSE OVERNIGHT LOWS IN THE 60S. FINALLY...MOISTURE
BEGINS TO INCREASE AGAIN BY SUNDAY BUT EXPECT UPSTREAM FRONTAL SYSTEM
TO REMAIN TO OUR NORTH UNTIL AT LEAST MONDAY OF NEXT WEEK. MEX MOS
GUIDANCE JUST ABOVE CLIMATOLOGY FOR NEXT WEEKEND AND NUMBERS VERY
CLOSE TO ENSEMBLE MEANS./40/

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL WITH LITTLE IN THE WAY OF DEEP CUMULUS
DEVELOPMENT EXPECTED THIS AFTN. SOME PATCHY AREAS OF MVFR FOG WILL
DEVELOP BETWEEN 08-13Z TUESDAY...PRIMARILY IN MEI/HBG AREA. THE RISK
FOR ISOLATED SHOWER/TSTM ACTIVITY WILL INCREASE TUES AFTN. /EC/
