AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 300 AM CDT SAT AUG 11 2001 TROPICAL AIRMASS STILL IN PLACE OVER THE CWFA...AND CONDITIONS WILL REMAIN FAVORABLE FOR A WET WEEKEND. SEVERAL FACTORS WILL COME INTO PLAY FOR THE FORECAST TODAY. MODELS ARE AGAIN FAIRLY SIMILAR IN THE SYNOPTIC FEATURES FOR THE FORECAST PERIOD. 500MB SHEAR AXIS TO REMAIN STATIONARY OVER EASTERN PORTIONS OF THE CWFA THROUGH LATE SUNDAY. FRONTAL BOUNDARY TO THE NORTH WILL REMAIN NEARLY STATIONARY OVER THE MS/TN BORDER THROUGH LATE SUNDAY TOO...BEFORE MEANDERING SOUTHWARD. TODAYS FORECAST WILL ALSO RELY HEAVILY ON MESOSCALE FEATURES. FIRST...THE WEAKENING MCS OVER ARKANSAS SHOULD LAY DOWN A BOUNDARY OVER AREAS ALONG AND WEST OF THE MISSISSIPPI RIVER...WHICH WILL ALLOW AFTERNOON CONVECTION TO FOCUS UPON IT THIS AFTERNOON OVER THE NORTHWEST AND WEST CENTRAL CWFA. ANOTHER CONCERN IS THE SOUTHWEST CWFA...THIS AREA COULD SEE THE MOST SUNSHINE THIS AFTERNOON...AND WITH A SOUTHWARD MOVING OUTFLOW BOUNDARY...STRONG AFTERNOON CONVECTION WILL FIRE. THERE IS ALSO A SKINNY SECTION OF THE CENTRAL CWFA WHERE ONLY A THIN LAYER OF MID LEVEL CLOUDS ARE BEING DETECTED. WITH FAIRLY DENSE CLOUD COVER BACK TO THE NORTHWEST AND TO THE EAST...A DIFFERENTIAL HEATING BOUNDARY COULD CAUSE CONVECTION TO OCCUR. IN THE EAST...IR IMAGERY SHOWING TOPS SLIGHTLY COOLING AND AN AREA SHOWERS AND THUNDERSTORMS MOVING SOUTHWARD. THIS SITUATION IS SIMILAR TO THE PAST SEVERAL NIGHTS WHERE GOOD UPGLIDE AND RISING THETA SURFACES HAVE SET UP AN UPPER LEVEL BAROCLINIC ZONE (AROUND 850MB)...TONIGHT/EARLY THIS MORNING IS NO DIFFERENT. PRECIP SHOULD LINGER UNTIL MID MORNING BEFORE AFTERNOON HEATING AND THE 500MB SHEAR AXIS WILL LEND TO THUNDERSTORM DEVELOPMENT OVER THIS AREA. WITH THE TROPICAL AIRMASS IN PLACE AND PWS OVER 2 INCHES TODAY...THINK HEAVY RAINFALL WORDING IS NEEDED WITH AMOUNTS OF 1 TO 2 INCHES AND HOUR WITH LOCALLY HIGHER 3 INCH AMOUNTS POSSIBLE. IN THE LATTER PERIODS OF THE FORECAST...SHEAR AXIS WILL DEFINITELY FOCUS PRECIP IN THE EAST. SAGGING FRONTAL BOUNDARY WILL ALSO TEND TO FOCUS PRECIP LATE SUNDAY INTO MONDAY. WITH AIRMASS REMAINING VERY MOIST THROUGH 60 HOURS (PWS AOA 2 INCHES) THINK LIKELY POPS WILL BE NEEDED MOST PLACES. SOMEWHAT DRIER AIR SEEMS TO FILTER IN BEHIND THE SOUTHWARD MOVING FRONTAL BOUNDARY IN THE EXTENDED PERIOD AND A RETURN TO A MORE DIURNAL PATTERN WILL MOST LIKELY RESULT. CURRENT EXTENDED SEEMS TO HAVE THIS REFLECTED AND WILL ONLY MAKE COSMETIC CHANGES DUE TO SOME SHIFTING OF ZONES. PRELIM NUMBERS... JAN 88/74/88/72 6463 MEI 86/73/88/72 7574 .JAN... MS...NONE.

SCATTERED TO NUMEROUS THUNDERSTORMS CAN BE EXPECTED TODAY AND TONIGHT OVER THE FORECAST AREA...INCLUDING NORTHEAST LOUISIANA, EXTREME SOUTHEAST ARKANSAS, AND MUCH OF MISSISSIPPI.

THE MOISTURE COMBINED WITH DAYTIME HEATING, UPPER LEVEL DISTURBANCES, AND SEVERAL SURFACE BOUNDARIES WILL LEAD TO RAPID THUNDERSTORM DEVELOPMENT. ACTIVATION OF STORMS SPOTTERS...EMERGENCY MANAGEMENT PERSONNEL OR HAM RADIO OPERATORS IS NOT ANTICIPATED THROUGH TONIGHT. ...FLOODING... PLENTY OF MOISTURE IS AVAILABLE FOR LOCALLY VERY HEAVY RAINFALL TODAY AND TONIGHT ACROSS THE ENTIRE FORECAST AREA.
