AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MEMPHIS TN 1110 AM CDT MON APR 11 2005 .DISCUSSION...SURFACE ANALYSIS THIS MORNING PLACES COLD FRONT ACROSS EASTERN OKLAHOMA AND TEXAS WITH A WARM FRONT EXTENDING ACROSS MAINLY CENTRAL MISSISSIPPI. VISIBLE SATELLITE SHOWING EXTENSIVE CLOUD COVER ACROSS THE MID SOUTH AS A LARGE AREA OF SHOWERS AND THUNDERSTORMS AFFECTS THE FORECAST AREA THIS MORNING. WATER VAPOR IMAGERY OVER THE PAST COUPLE OF HOURS SHOWING DRY SLOT WIDENING ACROSS SOUTHWEST TEXAS. MAIN FORECAST CONCERN FOR THIS AFTERNOON AND TONIGHT IS SEVERE WEATHER POTENTIAL. 12Z UPPER AIR ANALYSIS SHOWS 40KT 850MB LOW LEVEL JET ACROSS LOUISIANA TRANSPORTING +10-14C DEWPOINTS INTO THE LOWER MISSISSIPPI VALLEY...5C OR GREATER 700 MB DEWPOINT DEPRESSIONS UPSTREAM...AND UPPER LEVEL DIFLUENCE NOTED AT 250 MB ACROSS THE LOWER MISSISSIPPI VALLEY. CURRENT DATA SUGGESTS THAT BEST SEVERE POTENTIAL MAY BE POSSIBLE MAINLY THIS EVENING ESPECIALLY ALONG AND SOUTH OF I-40...ROUGHLY ABOUT THE SAME TIME UPPER LEVEL DIVERGENCE BEGINS TO MOVE EAST. MOST UNSTABLE CAPES WILL INCREASE TO AROUND 1400 J/KG BY MID TO LATE EVENING. NEARLY UNIDIRECTIONAL WINDS AT 850/500 MB SUGGEST PRIMARY THREAT WOULD BE IN THE FORM OF DAMAGING WINDS. A SUPERCELL OR CIRCULATIONS WITHIN THE CONVECTIVE LINE WILL BE POSSIBLE AS BACKING SURFACE WINDS AND 0-6KM BULK SHEAR VALUES AT OR ABOVE 40KTS ARE EXPECTED INTO THIS EVENING. WILL UPDATE GRIDS TO REFLECT CURRENT TRENDS. GRIDS WILL BE PUBLISHED SHORTLY. CJC .PREV DISCUSSION...ISSUED 330 AM CDT MON APR 11 2005. UPPER LOW IN EXTREME WESTERN KANSAS WITH SURFACE LOW OVER CENTRAL KANSAS EARLY THIS MORNING. COLD FRONT SOUTHWARD INTO TEXAS. CONVECTION OVER MISSOURI IS LIFTING NORTH...BUT AREAS OF THUNDERSTORMS OVER OK AND TX HAVENT BEEN MAKING MUCH PROGRESS EASTWARD. ABUNDANT CLOUD COVER HAS BEEN KEEPING TEMPERATURES IN THE MIDDLE 60S ACROSS MUCH OF THE CWA. && .SHORT TERM (THROUGH WEDNESDAY)... MODELS TAKE UPPER AND SURFACE LOWS PRETTY MUCH DUE EASTWARD THROUGH TUESDAY EVENING. 06Z NAM A LITTLE FURTHER NORTH WITH THESE FEATURES THAN THE 00Z GFS...WITH SYSTEM NEAR STL AT 00Z WED. APPARENT THAT GFS HAS FEEDBACK ISSUES AT 18Z TODAY OVER OUR AREA. THAT BEING SAID...WE ARE STILL GOING TO SEE RAIN AND THUNDERSTORMS. SOME HINTS ON WATER VAPOR OF A JET STREAK MOVING ACROSS BIG BEND AREA OF TEXAS EARLY THIS MORNING. INSTABILITY STILL THE MAJOR LIMITING FACTOR IN SIGNIFICANT CONVECTION DURING THE DAYTIME HOURS TODAY. SOUNDINGS VERY MOIST DURING THE FIRST HALF OF THE DAY...AND SOME QUESTION AS TO THE AMOUNT OF SUN WE WILL SEE. WE WILL NEED SOME HEATING TO BREAK THE CAP ANYTIME BEFORE LATE AFTERNOON. SATELLITE SHOWS PLENTY OF BREAKS IN CLOUD COVER ACROSS OUR CWA...BUT WITH SOUTHERLY FLOW...THIS COULD FILL IN WITH STRATUS OVER THE NEXT FEW HOURS. COULD SEE SOME SHOWERS THIS MORNING...BUT ANY SIGNIFICANT CONVECTION WILL NEED TO WAIT UNTIL THE LATE AFTERNOON AND EVENING HOURS TO DEVELOP. EARLY ON...THERE WILL BE ENOUGH TURNING TO PROMOTE DEVELOPMENT OF SUPERCELLS...BUT EXPECT THE PREDOMINANT CONVECTIVE MODE TO BECOME LINEAR BY SUNSET OR SO. HAIL AND DAMAGING WINDS WILL BE MAIN THREATS...BUT CANT RULE OUT A TORNADO...ESPECIALLY SOUTHERN PORTIONS OF CWA. MAIN IMPULSE SHOULD BE CLEAR OF THE AREA BY 09Z TUESDAY...ENDING LARGEST THREAT OF SEVERE WEATHER. MODELS SHOW WE SHOULD DRY SLOT FOR MOST OF THE DAY ON TUESDAY. AS COLD CORE DRIFTS SOUTHEAST OVER THE AREA TUESDAY AFTERNOON...THERE MAY BE JUST ENOUGH MOISTURE TO DEVELOP A FEW THUNDERSTORMS. WITH STEEP LAPSE RATES AND COLD 500 MB TEMPS...COULD SEE A FEW HAILERS NEAR THE UPPER LOW. WILL NOT PLAY UP THIS POTENTIAL AT THIS TIME... BUT WILL KEEP AN EYE ON IT. UPPER LOW WILL WOBBLE AROUND THE AREA TUESDAY NIGHT THROUGH WEDNESDAY NIGHT. SCATTERED SHOWERS/THUNDERSTORMS POSSIBLE UNDER THE LOW...WITH PLENTY OF CLOUD COVER. TEMPERATURES TODAY WILL DEPEND ON CLOUD COVER. GFS FEEDBACK ISSUES LEAD ME TO DISCOUNT MAV HIGH TEMP GUIDANCE TODAY...ESPECIALLY SINCE MEM CURRENTLY 68...MAV FORECAST HIGH 68. JBR SIMILAR. TENDING TOWARD WARMER VALUES CURRENTLY IN FORECAST. FOR THE REMAINDER OF THE SHORT TERM PERIOD...CURRENT FORECAST AND NUMERIC GUIDANCE CLOSE... SO WONT MAKE MAJOR CHANGES. && .LONG TERM (AFTER WEDNESDAY)... UPPER LOW TO MOVE AWAY FROM THE AREA THURSDAY MORNING...WITH SHOWERS DEPARTING WITH IT. GFS CONTINUES YESTERDAYS TREND OF DEVELOPING A RIDGE OVER THE MIDSOUTH. THIS WOULD KEEP WEEKEND FORECAST DRY. ONCE UPPER LOW MOVES AWAY FROM THE AREA...EXPECT TEMPERATURES TO BE NEAR OR SLIGHTLY ABOVE MID-APRIL NORMS. && .MEG WATCHES/WARNINGS/ADVISORIES... AR...NONE. MO...NONE. MS...NONE. TN...NONE. && WAGNER
