AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 551 PM CDT WED MAY 13 2009 .UPDATE... REMNANT MCV INTO SOUTHERN ILLINOIS. CONVECTION HAVING A VERY DIFFICULT TIME GENERATING PERSISTENT CORES WITH ANY APPRECIABLE ROTATION. THE LIMITING FACTOR ALL ALONG WAS ONLY MARGINALLY SUPPORTIVE WIND FIELDS FROM 700-300 MB IN THE 30-40 KT RANGE NOT INCREASING WITH HEIGHT FOR SPEED SHEAR...WHILE UNIDIRECTIONAL. ALREADY CLEARED SE MISSOURI COUNTIES. WE MAY SEE SOME WIND GUSTS BASED ON THE LATEST TRENDS...IF THEY CAN TRANSLATE TO THE SURFACE IN THE COMPACTING MCV AS IT HEADS TOWARD THE WABASH RIVER. BUT AT THIS TIME...RETURNS ARE NOT TOO IMPRESSIVE. LOW LEVEL WINDS ARE STILL DECENT...WITH AN UNSTABLE FETCH INTO THE CONVECTION FROM WEST KY AND SE MO. CELLS MAY STILL INTENSIFY IN WATCH AREA. ALSO UPDATED THE AVIATION SECTION BELOW FOR THE UPCOMING 00Z TAF ISSUANCE. ...NOLES... && .DISCUSSION... /ISSUED 240 PM CDT WED MAY 13 2009/ DISCUSSION... MCV MOVING INTO SE MISSOURI THIS AFTERNOON WITH INCREASING CONVECTION VERY CLOSE TO OUR SE MISSOURI COUNTIES. OVER THE REMAINDER OF THE AREA...CAP IS SLOWLY WEAKENING BUT STILL PRESENT...WITH NIL ACTIVITY ON THE RADAR. CAPE VALUES ALONG AND WEST OF THE MISSISSIPPI RIVER RUNNING 1500-2000 SURFACE BASED WITH LI/S BELOW -6. WILL CONTINUE TO MONITOR THIS AREA...BUT WITHOUT A FOCUS FOR LIFT...MAY BE HARD TO GEN UP CONVECTION THROUGH THE END OF THE DAY. THE PRESENCE OF THE MCV AND ATTENDANT FORCING TO ITS SOUTH MAY HAVE TO BE THE FOCUS FOR CONVECTIVE DEVELOPMENT ACROSS WESTERN PORTIONS OF THE REGION. ONLY OTHER FEATURES ARE WEAK CONVERGENCE NEAR THE MISSISSIPPI RIVER...AND POTENTIALLY OUTFLOW ACROSS SOUTHERN ILLINOIS UP NEAR INTERSTATE 64 FROM EARLIER CONVECTION TO OUR NORTH. SPC CONTINUES TO OUTLOOK SE MISSOURI AND SRN ILLINOIS IN A MODERATE RISK AREA...WHICH IS PLAUSIBLE. VERY UNSTABLE CONDITIONS COUPLED WITH DECENT LOW LEVEL WIND FIELDS AND POTENTIALLY REMNANT BOUNDARIES COULD RESULT IN DISCRETE CELLS CAPABLE OF HAIL...STRONG WINDS AND POSSIBLY A TORNADO. IN THE VERTICAL...SPEED SHEAR IS ONLY MARGINAL...WITH LITTLE CHANGE IN A 30-40KT PROFILE FROM 700-300MB. THEREFORE EVEN THOUGH WE MAY SEE DISCRETE CELLS... PERSISTENCE MAY NOT BE AS PROMINENT. SHOULD BE EVOLUTIONARY TONIGHT AS INSTABILITY SHIFTS FARTHER NORTHWEST INTO SRN ILLINOIS AND SE MISSOURI AFTER 00Z...AHEAD OF A COLD FRONTAL BOUNDARY. POPS WILL GO INTO CATEGORICAL RANGE...AND MODE SHOULD BECOME MORE LINEAR AND BROAD SCALE COVERAGE WISE THROUGH 06Z. AFTER 06Z INSTABILITY DIMINISHES...WITH WHAT SHOULD BE A LOWERING THREAT OF SEVERE WEATHER LATE...AS THE BOUNDARY SETTLES SOUTH TO THE OHIO RIVER AND WEAKENS AND STALLS...WITH LIKELY POPS SOUTHERN SECTIONS BY THURSDAY MORNING. A CONTINUED UNSETTLED PATTERN WILL PERSIST THROUGH SATURDAY WITH A COLD FRONT COMING INTO THE REGION BY LATE SATURDAY AFTERNOON INTO EARLY SATURDAY NIGHT. THEREFORE CANNOT ELIMINATE POPS FROM ANY PERIOD. BUT THE NEXT BEST CHANCES WILL LIKELY BE FRIDAY WITH A POTENTIAL MCS...AND WITH THE FRONT LATE SATURDAY INTO EARLY SATURDAY NIGHT. THE OPS MODELS AND ENSEMBLES CONTINUE TO SUPPORT DRY WEATHER SUNDAY THROUGH THE MIDDLE PART OF NEXT WEEK...WITH HIGH PRESSURE DOMINANT FOR THE MOST PART...ACROSS THE EASTERN PART OF THE NATION. WILL LET WIND ADVISORY CONTINUE THROUGH EARLY EVENING IN WIND DAMAGE AREAS OF SE MISSOURI AND SRN ILLINOIS...WITH THE LAKE WIND ADVISORY CONTINUING THROUGH 6 PM ELSEWHERE. && .AVIATION... WILL MONITOR KEVV AND KOWB FOR CONVECTIVE TRENDS EARLY ON. BEST CHANCE OF CONVECTION AT ALL THE TAF SITES WILL BE LATER ON AS A COLD FRONT SETTLES SOUTH INTO THE REGION OVERNIGHT. GENERALLY VFR CONDITIONS OUTSIDE OF CONVECTION. SHORT TERM...KPAH AND KCGI TAF SITES WILL LIKELY BE FREE OF CONVECTION THROUGH 06Z. && .PAH WATCHES/WARNINGS/ADVISORIES... KY...NONE. MO...NONE. IL...NONE. IN...NONE. &&
