AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 200 PM CDT SAT JUL 5 2003 LATEST RADAR AND SATELLITE IMAGERY SHOW WIDESPREAD...DEEP AND VERY MOIST CONVECTIVE ACTIVITY OVER MUCH OF THE FORECAST AREA...ESPECIALLY OVER SOUTHERN MISSISSIPPI. MORNING BALLOON SOUNDINGS SHOW PRECIPITABLE WATER VALUES OVER TWO INCHES IN MANY LOCATIONS...SUGGESTING THAT MOST SHOWERS AND THUNDERSTORMS WILL HAVE LITTLE PROBLEM PRODUCING LOCALLY HEAVY RAINS. FURTHERMORE...THE MOISTURE DEPTH ON THE SOUNDINGS EXTENDS UP TO ABOUT 450 MB AND THE WIND FLOW AT ALL LEVELS IS VERY WEAK. AT THE SURFACE...SOILS REMAIN NEARLY SATURATED FROM RECENT RAINS...MAINLY SOUTH OF INTERSTATE 20 AND EAST OF THE MISSISSIPPI RIVER. BASED ON THESE OBSERVATIONS...A FLASH FLOOD WATCH HAS BEEN ISSUED FOR SOUTHEASTERN MISSISSIPPI THROUGH 800 PM. TONIGHT THROUGH SUNDAY NIGHT...EXPECT THE MOSTLY DIURNALLY DRIVEN CONVECTIVE ACTIVITY TO DIMINISH IN COVERAGE AND INTENSITY BY LATE THIS EVENING AS MOST OF THE DAILY HEATING IS LOST. LOW CLOUD CEILINGS WILL FORM ACROSS MANY LOCATIONS AS MOISTURE FROM THE DAY/S RAINS IS LIFTED ABOVE THE SURFACE. ON SUNDAY...THE SOUTHERLY FLOW OF VERY MOIST...WARM AND UNSTABLE AIR WILL CONTINUE OVER THE REGION. EXPECT...A REPEAT OF TODAY/S WEATHER. AS WAS THE CASE TODAY...WEAK ATMOSPHERIC FLOW AT ALL LEVELS WILL TRANSLATE TO A SLOW SOUTHWESTERLY STORM MOTION...AND ABUNDANT CLOUD COVER WILL HOLD THE AFTERNOON HIGH TEMPERATURES IN THE MID 80S. AS A RESULT...THE POTENTIAL FOR FLASH FLOODING SUNDAY WILL BE A CONCERN...ESPECIALLY SOUTH OF INTERSTATE 20. ON SUNDAY EVENING THE SHOWER ACTIVITY WILL AGAIN DIMINISH. ON MONDAY AND TUESDAY...THE PATTERN WILL BEGIN TO CHANGE AS THE BERMUDA HIGH TO THE EAST AND THE FOUR CORNERS HIGH TO THE WEST BEGIN TO INTENSIFY. THE AMPLIFICATION OF THE TWO HIGH PRESSURE AREAS OVER THE AREA WILL ALLOW FOR THE MAINLY AFTERNOON THUNDERSTORMS TO DIMINISH IN AREAL COVERAGE...TO BE MORE OF THE SCATTERED VARIETY. DUE TO UNSEASONABLY HIGH PRECIPITABLE WATER VALUES...THE THUNDERSTORMS THAT OCCUR ON THESE DAYS ARE EXPECTED TO BE MORE OF THE HEAVY RAIN PRODUCING TYPE THAN THE SEVERE TYPE. DAY TIME TEMPERATURES WILL RISE TO NORMAL LEVELS AS SUBSIDENCE ADDS TO THE DAILY HEATING. WEDNESDAY THROUGH SATURDAY...THE TREND TOWARDS DRIER AND HOTTER WILL CONTINUE AS THE FOUR CORNERS HIGH PRESSURE AREA MIGRATES EASTWARD AND AS THE ASSOCIATED THERMAL TROUGH TO THE WEST BECOMES MORE SHALLOW...AND BEGINS TO ENCROACH ON LOUISIANA. AS THIS HAPPENS...EXPECT TEMPERATURES TO RISE TO BE SLIGHTLY ABOVE NORMAL AND FOR THE AFTERNOON THUNDERSTORM ACTIVITY TO DIMINISH FURTHER IN AREAL COVERAGE.

SCATTERED THUNDERSTORMS ARE ANTICIPATED ACROSS THE REGION THIS EVENING...BEFORE BECOMING MORE ISOLATED OVERNIGHT. MORE SCATTERED THUNDERSTORM ACTIVITY IS EXPECTED DURING THE DAY SUNDAY. SEVERE THUNDERSTORMS ARE NOT ANTICIPATED. AN EXTREMELY MOIST AIRMASS WAS IN PLACE ACROSS THE LOWER MISSISSIPPI VALLEY THIS WEEKEND. THE COMBINATION OF THE VERY MOIST AIRMASS AND A DISTURBANCE IN UPPER LEVELS OF THE ATMOSPHERE WILL LEAD TO THUNDERSTORM DEVELOPMENT TONIGHT THROUGH SUNDAY. THE THUNDERSTORMS WILL BE MOST NUMEROUS DURING THE AFTERNOON AND EVENING HOURS DUE TO DAYTIME HEATING. WHILE VERY MOIST...THE AIRMASS ACROSS THE REGION IS NOT PARTICULARLY UNSTABLE...SO SEVERE STORMS ARE NOT EXPECTED.

A FLASH FLOOD WATCH IS IN EFFECT FOR THIS AREA THROUGH 8 PM TONIGHT. WITH AN EXTREMELY MOIST AIRMASS IN PLACE ACROSS THE AREA...SHOWERS AND THUNDERSTORMS WHICH DEVELOP WILL BE CAPABLE OF PRODUCING TORRENTIAL DOWNPOURS OF RAIN.

WHILE HEAVY RAINFALL AMOUNTS ARE NOT EXPECTED TO BE WIDESPREAD...LOCALIZED AMOUNTS OF UP TO 2 INCHES IN LESS THAN AN HOUR COULD OCCUR. THESE TYPES OF RAINFALL AMOUNTS COULD LEAD TO FLASH FLOODING OF STREAMS AND ROADS...PARTICULARLY OVER PARTS OF CENTRAL AND SOUTHERN MISSISSIPPI THAT HAVE SEEN SIGNIFICANT RAIN RECENTLY...AND HAVE SATURATED GROUND. .DAYS TWO THROUGH SEVEN...SUNDAY NIGHT THROUGH SATURDAY...
