AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MEMPHIS TN 1048 AM CDT FRI JUL 20 2007 .DISCUSSION... PRIMARY CHALLENGE THIS MORNING WILL BE DETERMINING CHANCES FOR CONVECTION ACROSS THE MID SOUTH TODAY. CURRENTLY...A COLD FRONT IS ENTERING INTO EXTREME NORTHERN PORTIONS OF THE MID SOUTH WITH A CONVECTIVE OUTFLOW BOUNDARY SOUTH OF THE FRONT EXTENDING FROM NORTHEAST MISSISSIPPI THROUGH SHELBY COUNTY TENNESSEE AND BACK INTO EAST CENTRAL ARKANSAS. THE BEST INSTABILITY AND SURFACE HEATING CONTINUES TO BE ALONG AND SOUTH OF THIS CONVECTIVE OUTFLOW BOUNDARY. IN THESE AREAS...SURFACE BASED CAPE VALUES ALREADY RANGE BETWEEN 1500-2500J/KG WITH LI/S TO -4C BASED ON THE LATEST MESOANALYSIS. EXPECT CONTINUED INSOLATION TO PUSH AFTERNOON SBCAPE VALUES TO BETWEEN 2500-3500J/KG SOUTH OF THE OUTFLOW BOUNDARY. LATEST THINKING IS THAT CONVECTION WILL CONTINUE TO INITIATE ALONG THIS OUTFLOW BOUNDARY AS IT SINKS SLOWLY SOUTH AND ALSO GETS ADDITIONAL UPPER LEVEL FORCING FROM A SOUTHEAST MOVING SHORTWAVE DISTURBANCE CURRENTLY NOTED ON WATER VAPOR IMAGERY OVER SOUTHERN ILLINOIS. SO NORTH MISSISSIPPI AND EAST ARKANSAS SHOULD HAVE THE GREATEST CHANCES FOR THUNDERSTORMS THIS AFTERNOON/EVENING AND CONSIDERING INSTABILITY VALUES IN PLACE EXPECT A FEW STORMS MAY APPROACH SEVERE LIMITS WITH ISOLATED DAMAGING WIND GUSTS POSSIBLE. FURTHER NORTH...CANNOT COMPLETELY RULE OUT ISOLATED TO SCATTERED THUNDERSTORMS AHEAD OF THE FRONT WHERE THE ATMOSPHERE WILL REMAIN MOIST AND SLIGHTLY UNSTABLE. ONE NEGATIVE FACTOR FOR CONVECTION NORTH OF THE OUTFLOW BOUNDARY AND SOUTH OF THE FRONT WILL BE LACK OF LOW LEVEL CONVERGENCE AS SURFACE WINDS HAVE BACKED TO THE NORTH AND NORTHEAST ALREADY. AS FOR TEMPERATURES AND CLOUD COVER...THE CURRENT FORECAST LOOKS GOOD FOR MOST AREAS. ONLY ADJUSTMENT WILL BE TO UP TEMPERATURES A FEW DEGREES OVER EXTREME SOUTHERN AREAS RECIEVING A GOOD AMOUNT OF SUN AND WHERE TEMPERATURES ARE ALREADY NEARING EARLIER FORECASTED HIGHS. UPDATED ZONES...GRIDS...AND HWO OUT SHORTLY. && .PREV DISCUSSION... /ISSUED 349 AM CDT FRI JUL 20 2007/ DISCUSSION... DETERMINING RAIN CHANCES TODAY IS THE FORECAST PROBLEM OF THE DAY. SHORT TERM MODELS WERE IN GOOD GENERAL AGREEMENT AND USED A BLEND OF THEM. BESIDES LOWERING RAIN CHANCES TODAY THROUGH SATURDAY...MADE NO SIGNIFICANT CHANGES TO THE PREVIOUS FORECAST. AT 345 AM CDT ACROSS THE MIDSOUTH...NUMEROUS SHOWERS AND THUNDERSTORMS WERE NORTHEAST OF JACKSON TN WHERE A SHORT WAVE/LOW PRESSURE DISTURBANCE WAS LOCATED. TEMPERATURES WERE IN THE 70S... AND THE AIR WAS MOIST AND UNSTABLE. AN OUTFLOW BOUNDARY WAS LOCATED FROM HARRISBURG AR TO SAVANNAH TN AND WAS MOVING SOUTH. A COLD FRONT EXTENDED ACROSS CENTRAL MO TO NORTHERN KY. TODAY...DECIDED TO LOWER RAIN CHANCES OVER THE AREA AS MOISTURE CONVERGENCE ALONG THE APPROACHING COLD FRONT AND OUTFLOW BOUNDARY OVER THE AREA WILL BE WEAK WITH LOW LEVEL WINDS VEERING TO THE NORTHWEST BEHIND THE DEPARTING SHORT WAVE. DO NOT THINK THE ENTIRE MIDSOUTH WILL RECEIVE RAIN TODAY. KEPT THE HIGHEST RAIN CHANCES SOUTH OF INTERSTATE 40 TODAY... AROUND 50 PERCENT...WHERE THE OUTFLOW BOUNDARY AND DEEPEST MOISTURE WILL BE LOCATED...BUT AGAIN CONVERGENCE WILL BE WEAK. LOCATIONS NORTHEAST OF JACKSON TN WILL GET WET THROUGH 7 AM CDT NEAR THE SHORT WAVE AND MAY GET UP TO AN INCH OF RAINFALL...BUT OTHERWISE...ANY RAIN WILL BE SCATTERED IN NATURE. EXPECT A FEW STORMS TO DEVELOP ONCE TEMPERATURES REACH THE UPPER 80S...PROBABLY NEAR THE FRONT AND OLD OUTFLOW BOUNDARY. A STORM OR TWO COULD BE STRONG WITH LOCALLY HEAVY RAINFALL OVER AN INCH AND GUSTY WINDS UP TO 40 MPH AS THE AIR WILL BE MOIST AND UNSTABLE...BUT SEVERE STORMS APPEAR UNLIKELY. CLOUDS WILL KEEP TEMPERATURES DOWN A BIT TODAY WITH HIGHS MAINLY IN THE UPPER 80S. TONIGHT AND SATURDAY...QUICKER DRYING CAN BE EXPECTED AS THE FRONT PUSHES THROUGH...SO LOWERED/REMOVED RAIN CHANCES AND DECREASED CLOUD COVER. AN ISOLATED STORM IS POSSIBLE THROUGH 10 PM CDT SOUTH OF INTERSTATE 40 NEAR THE FRONT. OTHERWISE...MOSTLY CLEAR AND MUCH COOLER CONDITIONS CAN BE EXPECTED TONIGHT. WOULD NOT BE SURPRISED IF PATCHY FOG DEVELOPED IN SOME LOCATIONS AFTER MIDNIGHT CDT TONIGHT. LOWS TONIGHT WILL BE COOLER...MAINLY IN THE 60S...AND HIGHS SATURDAY WILL BE NEAR 90 WITH ABUNDANT SUN...THOUGH HUMIDITY VALUES WILL BE LOW WITH DEWPOINTS FALLING INTO THE 50S...MAKING THE AIR FEEL COMFORTABLE THIS WEEKEND. SATURDAY NIGHT THROUGH THURSDAY...GENERALLY DRY AND MOSTLY CLEAR CONDITIONS WITH TEMPERATURES SLOWLY REBOUNDING TO NEAR NORMAL CAN BE EXPECTED. RECORD LOW TEMPERATURES ARE FORECAST SUNDAY AND MONDAY MORNING AT JACKSON TN WITH UNSEASONABLY COOL READINGS IN THE MID TO UPPER 50S. HIGHS WILL BE IN THE LOWER 90S EACH DAY. MODELS HINT THAT MOISTURE MAY RETURN AS A LOW PRESSURE SYSTEM OVER THE EAST U.S. RETROGRADES WEST TOWARDS THE AREA BEYOND MONDAY...BUT FOR NOW...KEPT MAINLY DRY CONDITIONS. && .PRELIMINARY POINT TEMPS/POPS...
