NWS Jackson, MS wrote its last area forecast discussion before the first event at Aug 13, 2:09 PM CST, 36 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 309 PM CDT TUE AUG 13 2013 .DISCUSSION... .SHORT TERM... AN UPPER TROUGH IS WORKING ITS WAY THROUGH THE DEEP SOUTH TODAY AND TOMORROW. THE ASSOCIATED SLOW-MOVING COLD FRONT PROGRESSING SOUTHWARD ALONG WITH IT IS BRINGING MORE WIDESPREAD RAINFALL TO THE AREA TODAY. THE FRONT IS CURRENTLY SITTING NORTH OF THE CWA. ALONG THE FRONT IS A DISSIPATING CLUSTER OF SHOWERS WITH WIDESPREAD SCATTERED THUNDERSTORMS OUT AHEAD OF THE BOUNDARY WHERE ALL THE INSTABILITY IS LOCATED AT THE MOMENT. DEWPOINTS ARE IN THE MID 70S WHICH LEAVE THE AREA IN VERY HUMID AND STICKY CONDITIONS. THE ARKLAMISS IS SITTING IN AN AREA OF 2+IN. PWS. DUE TO THIS THE SHOWERS WE ARE EXPERIENCING ARE CAPABLE OF DUMPING VAST AMOUNTS OF PRECIP IN SHORT TIME PERIODS. TONIGHT...MODELS ARE INDICATING INCREASED SURFACE CONVERGENCE ALONG THE FRONTAL BOUNDARY. THIS WILL LEAD TO PRETTY GOOD RAIN CHANCES LATE IN THE NIGHT ALONG AND SOUTH OF THE FRONT. WEDNESDAY WILL BE WET EARLY ON BUT AS THE FRONT PROGRESSES SOUTH-SOUTHEASTWARD THE ATMOSPHERE WILL STABILIZE FROM THE NORTH TO THE SOUTH. THE MORNING RAINFALL AND CLOUDS SHOULD LIMIT DESTABILIZATION THE REST OF THE DAY. HOWEVER...WHERE INSOLATION CAN OCCUR...MOST LIKELY IN SCATTERED POCKETS...THERE ARE CHANCES A FEW STORMS COULD FORM AND PRODUCE SOME STRONG WIND GUSTS. WITH THE PASSING OF THE FRONT...COOLER AND DRIER AIR WILL FILTER INTO THE AREA. WEDNESDAY TEMPS WILL BE IN THE MID/UPPER 80S DUE TO THICK CLOUD COVER AND THE EXPECTED PRECIP. TEMPERATURES ON THURSDAY HOWEVER WILL REACH ONLY INTO THE MID/UPPER 80S THANKS TO NORTHERLY FLOW. WITH SKIES MOSTLY CLEAR AND DEWPOINTS ONLY IN THE 50S...THURSDAY WILL BE A VERY PLEASANT DAY. LOW TEMPS WILL THEN DROP INTO THE LOW 60S BY FRIDAY MORNING...TEMPERATURES NOT SEEN SINCE LATE JUNE. /10/ .LONG TERM... (THURSDAY THROUGH TUESDAY). LONG RANGE MODELS AND ENSEMBLES ARE IN GENERAL AGREEMENT ON THE PATTERN WHICH WILL BRING SOME SMALL CHANCES OF RAIN AND SOME SLIGHT RELIEF AT NIGHT. SOME DRIER AIR WILL PUSH INTO THE REGION FROM THE NORTH THURSDAY INTO FRIDAY WITH PWATS JUST UNDER AN INCH. THIS WAS CONFIRMED BY AREA MODEL CROSS SECTIONS. WITH THE FRONT BEING STATIONARY ACROSS THE SOUTH...A SERIES OF WEAK DISTURBANCES WILL COME ACROSS THE REGION. THERE COULD BE A FEW STRONG STORMS DURING THE PERIOD NEAR THE DECAYING FRONTAL BOUNDARY...WHICH WILL WASH OUT BY TUESDAY. THIS WILL PROVIDE SOME CHANCE OF RAIN FOR THE REST OF THE PERIOD. WITH THE LOWER PWATS DO NOT SEE THE RISK OF LOCALLY HEAVY RAINFALL DURING THE REST OF THE WORK WEEK. A SURGE OF MOISTURE WILL DEVELOP EAST OF THE REGION OVER THE WEEKEND...WHICH WILL BRING SOME MOISTURE IN FROM THE EAST AND SEND PWATS AROUND 1.5 INCHES. THE AIRMASS BEHIND THE FRONT WILL BRING SOME 60S DEWPOINTS AND TAKE A LITTLE HUMIDITY OUT OF THE AIR WITH SOMEWHAT COOLER NIGHTS. HIGHS AFTER THE FRONT WILL BE GENERALLY IN THE MID 80S TO LOWER 90S FOR THURSDAY AND FRIDAY. WITH LOWS BRINGING SOME NIGHT RELIEF OF READINGS IN THE 60S TO AROUND 70. THIS PATTERN WILL BRING SLIGHTLY BELOW NORMAL LOWS FOR THIS TIME OF YEAR. THE UPPER TROUGH AXIS WILL DEVELOP OVER THE REGION ON SATURDAY...BUT IT WILL WEAKEN AS WE GET SOME HEIGHT RISES BY SUNDAY INTO EARLY NEXT WEEK. THIS WILL LIFT OUR HIGHS INTO THE 90-94 RANGE FOR SUNDAY INTO EARLY NEXT WEEK. WE WILL GET BACK TO A FLAT MEAN RIDGE PATTERN FOR MONDAY INTO TUESDAY. AS FAR AS MODEL TEMPS ARE CONCERNED THE EURO LOOKED A LITTLE COOL BEHIND THE FRONT WITH HIGHS GENERALLY IN THE 80S FOR THE PERIOD. WENT CLOSE TO MEX GUIDANCE WITH HIGHS IN THE 80S TO LOWER 90S...WHICH RISE TO THE 90-94 RANGE BY EARLY NEXT WEEK. EURO LOWS LOOKED A LITTLE WARM AT NIGHT ESP FOR THE REST OF THE WORK WEEK. SO OPTED TO GO CLOSE TO MEX GUIDANCE WITH LOWS IN THE 60S...WHICH EVENTUALLY WARM TO AROUND 70 FOR EARLY NEXT WEEK. AS FAR AS POPS ARE CONCERNED WENT CLOSE TO MEX NUMBERS FOR THE PERIOD. THE EURO POPS WERE RATHER DRY WITH THE DECAYING FRONT AROUND UNTIL MONDAY IN THE SOUTHEAST. /17/ && .AVIATION... SHWRS AND TSTMS ARE MOVING ACROSS MOST TAF SITES THIS AFTERNOON BRINGING OCCASIONAL MVFR/IFR CONDITIONS. A FRONT HAS PUSHED MOST OF THE TSTM ACTIVITY TO THE SOUTH OF GTR/GLH/GWO...BUT LOW CLOUDS AND SHOWERS WILL CONTINUE TO BRING OCCASIONAL MVFR CONDITIONS TO THESE SITES THROUGH THE EVENING HOURS. SHOWERS AND OCCASIONAL MVFR CONDITIONS WILL BE POSSIBLE AT ALL SITES THROUGH THE NIGHT...BUT THERE WILL BE INCREASING CHANCES FOR TSTMS AT JAN/HBG/MEI/HBG WEDNESDAY MORNING. /15/ && .PRELIMINARY POINT TEMPS/POPS...
