NWS Jackson, MS wrote its last area forecast discussion before the first event at May 14, 10:10 AM CST, 1 hour 14 minutes earlier.
AREA FORECAST DISCUSSION...UPDATE NATIONAL WEATHER SERVICE JACKSON MS 1110 AM CDT THU MAY 14 2009 .DISCUSSION... UPDATE: THE CONVECTIVE OUTFLOW BOUNDARY REMAINS ACTIVE OVER WRN PORTIONS OF THE FORECAST AREA LATE THIS MORNING...BUT THUNDERSTORM INTENSITY HAS DIMINISHED SOME IN ACCORD WITH THE TYPICAL DIURNAL MINIMUM SEEN THIS TIME OF THE DAY. MEANWHILE SCATTERED SHOWER/TSTM ACTIVITY HAS DEVELOPED OVER CNTRL/ERN PORTIONS OF MS AHEAD OF THE BOUNDARY AND THIS SHOULD CONTINUE INTO THE AFTN. WITH VERY WEAK FLOW...MOST STORMS SHOULD BE OF THE PULSE TYPE AND UNORGANIZED. PRECIPITABLE WATER AIRMASS > 1.5 INCHES AND MIXED LAYER CAPE APPROACHING 3000 J/KG THIS AFTN WOULD YIELD A FEW STRONG TO SVR TSTMS WITH VERY HEAVY RAIN AND WILL KEEP THIS MENTION GOING IN THE HWO. IN THE FORECAST GRIDS...HAVE UPPED POPS SOME FOR THIS AFTN AND REMOVED TSTMS FROM PORTIONS OF THE DELTA REGION WHERE THE OUTFLOW BOUNDARY HAS ALREADY PASSED THROUGH. HAVE ALSO LOWERED HIGH TEMPS A LITTLE BEHIND THE BOUNDARY. THE UPDATED AVIATION DISCUSSION IS BELOW. /EC/ PREVIOUS UPDATE: UPDATE: A FEW ADJUSTMENTS WERE MADE TO THE NEXT FEW HOURS OF THE FORECAST GRIDS TO ACCOUNT FOR CONVECTIVE DEVELOPMENT ALONG THE OUTFLOW BOUNDARY. INCREASED POPS SLIGHTLY FOR NE LA AND NC MS. /EC/ PREVIOUS DISCUSSION... AS HEATING SUBSIDES THIS AFTERNOON CONVECTION SHOULD BEGIN TO CALM DOWN TO LEAVE THE REGION QUIET FOR THE MID AND LATE EVENING AND INTO THE OVERNIGHT HOURS. SOUTHERLY LOW LEVEL FLOW WILL CONTINUE OVER THE CWFA ON FRIDAY TO KEEP WARM AND MOIST CONDITIONS OVER THE CWFA. AS HEATING BEGINS OVER THE AREA...MORE DIURNAL CONVECTIONS IS EXPECTED TO DEVELOP OVER THE CWFA. THERE SHOULD NOT BE QUITE AS MUCH IN THE WAY OF LAPSE RATES OVER THE CWFA. THERE WILL ALSO BE AN UPPER RIDGE OVER THE CWFA. SO IT WILL BE SLIGHTLY HARDER TO SEE AS MUCH STRONG TO SEVERE STORMS OVER THE AREA ON FRIDAY. HOWEVER WILL NOT RULE OUT THE POSSIBILITY OF A COUPLE OF INTENSE STORMS. AGAIN ACTIVITY SHOULD BEGIN TO DIE DOWN BY THE EVENING HOURS TO LEAVE A RELATIVELY QUIET NIGHT FOR THE ARKLAMISS REGION FRIDAY NIGHT. TEMPERATURES WILL CONTINUE TO BE WARM OVER THE ARKLAMISS REGION FOR THE NEXT COUPLE OF DAYS WITH WEAK UPPER RIDGING AND SOUTHERLY LOW LEVEL FLOW CONTINUING OVER THE ARKLAMISS. HIGHS BOTH TODAY AND ON FRIDAY SHOULD REACH THE MIDDLE 80S ACROSS MOST OF THE REGION WITH A FEW LOCATIONS POSSIBLY REACHING THE UPPER 80S. LOW TEMPERATURES BOTH NIGHTS SHOULD BE IN THE MIDDLE TO UPPER 60S. OVERALL HAVE REMAINED WITH GUI FOR TEMPERATURES THROUGH THE NEXT COUPLE OF DAYS FOR THE ENTIRE REGION. /14/ LONG TERM(SATURDAY THROUGH THURSDAY)...MOISTURE ADVECTION INCREASES ON SATURDAY WITH PWATS RISING FROM 1.5 INCHES TO 1.7+ INCHES AHEAD OF INCOMING COLD FRONT FROM THE NW. THIS BOUNDARY SHOULD ARRIVE IN OUR NWRN ZONES SATURDAY NIGHT AND REACH THE SERN ZONES BY SUNDAY EVENING. RICH MOISTURE...DECENT INSTABILITY AND OUTFLOW BOUNDARIES WILL PRECEDE THE FRONT SATURDAY AFTERNOON WITH K INDEXES 30-35...MLCAPES 1500-2000J/KG AND 6C 7-500MB LAPSE RATES CONTRIBUTING TO A FEW STRONG TO SEVERE STORMS. EVEN THOUGH 850MB THETA E VALUES APPROACHING 330K...WIND SHEAR VALUES REMAIN QUITE LIMITED WITH 700-500MB MID LEVEL FLOW LESS THAN 15 KTS. THAT WILL LIMIT TSRA DEVELOPMENT TO MAINLY HAIL/ HEAVY RAIN PRODUCERS WITH SOME WIND GUSTS POSSIBLE INTO SATURDAY NIGHT. THEN...GFS/ECMWF MODELS BOTH SHOWING CONSIDERABLE POST-FRONTAL SHRA BAND LASTING UNTIL LATE SUNDAY NIGHT BEFORE ENDING FROM NW TO SE. A 1030MB+ SURFACE HIGH PROGGED TO SLIDE INTO THE MID MS VALLEY SUNDAY NIGHT WILL GIVE US SOME DRIER/COOLER AIR FOR THE FIRST COUPLE OF DAYS NEXT WEEK AS IT MOVES EWD. WHILE LIMITED MOISTURE COULD BACK WWD ACROSS THE GULF STATES ON TUESDAY...THE MORE CRITICAL FEATURE WILL PROBABLY BE THE DEVELOPMENT OF A 500MB CUTOFF LOW IN THE ERN GULF OF MEXICO. THE ECMWF IS FARTHER SE THAN THE GFS WITH THIS FEATURE ON ITS MOST RECENT RUNS FOR NEXT TUESDAY/WEDNESDAY. HOWEVER...BOTH SOLUTIONS AGREE THAT THE SYSTEM WOULD DRIFT NWD TOWARD THE FL PANHANDLE BY THURSDAY AND WILL INTRODUCE SOME POPS BY THAT TIME... MAINLY FOR PORTIONS OF MS. TEMP GUIDANCE SUPPORTS A DECENT DOSE OF CONTINUITY FOR SATURDAY/ SUNDAY AND HAVE GONE A LITTLE CLOSER TO ENSEMBLE MEANS AS WE HEAD INTO NEXT WEEK. EXPECT COOLEST DAY WILL COME ON SUNDAY WITH NLY LOW LEVEL FLOW AND EXTENSIVE CLOUD SHIELDS CONTINUING TO BRING IN A COOLER AIRMASS BEHIND THE FRONT. READINGS SHOULD DIP INTO THE 50S BOTH MONDAY AND TUESDAY MORNINGS(PROBABLY FOR THE LAST TIME THIS SPRING). THE COOL AIR WILL NOT LAST TOO LONG AS RIDGING AT THE MID AND UPPER LEVELS BUILDS INTO THE REGION TO BRING BACK ABOVE NORMAL TEMPERATURES TO THE ARKLAMISS REGION BY MID WEEK. /40/ && .AVIATION...MVFR/IFR CONDITIONS ARE GIVING WAY TO VFR CONDITIONS THIS MORNING OVER THE AREA. THERE WILL BE THE POSSIBILITY FOR SOME ISOLATED SHOWERS/THUNDERSTORMS TODAY...MAINLY DURING THE AFTERNOON AND EARLY EVENING. THIS ACTIVITY SHOULD QUICKLY DIE DOWN AFTER SUNSET. FOG/STRATUS WILL ONCE AGAIN BE POSSIBLE DURING THE EARLY MORNING ON FRIDAY BRINGING WITH IT IFR/LIFR CONDITIONS TO MUCH OF THE AREA. /15/ && .JAN WATCHES/WARNINGS/ADVISORIES... MS...NONE. LA...NONE. AR...NONE. &&
