NWS Paducah, KY wrote its last area forecast discussion before the first event at Jun 5, 6:12 AM CST, 3 hours 48 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 712 AM CDT SUN JUN 5 2011 .UPDATE... JUST SENT OUT GRID AND PUBLIC PRODUCT UPDATES TO ACCOUNT FOR THE CONVECTION MAKING ITS WAY TOWARD SE IL/SW IN/NW KY. RAISED POPS INTO THE LIKELY CATEGORY...AS THE WELL ORGANIZED CONVECTION SHOULD HOLD TOGETHER AND MOVE INTO THE CWFA. THE BEST CHANCE WILL BE ALONG THE I-64 CORRIDOR AND NORTH AND EAST. OTHERWISE THE POPS WERE LEFT PRETTY MUCH ALONE FARTHER SOUTH AND WEST INTO FAR WEST KENTUCKY AND SOUTHEAST MISSOURI. DID ADJUST CLOUD COVER AS WELL...BUT DID NOT ADJUST TEMPS YET. THE KEVV TRI-STATE AREA WILL NEED TO BE MONITORED THOUGH FOR TEMP ADJUSTMENTS THROUGH THE DAY. BELOW...IS THE ORIGINAL DISCUSSION FROM EARLIER AND THE UPDATED 12Z AVIATION DISCUSSION. && .DISCUSSION... CONVECTION ALREADY STARTING TO FIRE UP OVER NORTH CENTRAL MISSOURI EARLY THIS MORNING...IN RESPONSE TO A MID LEVEL WAVE. THROUGH THE DAY...AS MID LEVEL HEIGHTS FALL AND A WEAK COLD FRONT BACK DOORS THE REGION FROM THE EAST...WILL CONTINUE WITH OUR CHANCE POPS FOR SHOWERS AND STORMS...WITH HIGHEST POPS KEVV TRI-STATE TO LOWEST POPS OZARK FOOTHILL REGION OF SE MISSOURI. GIVEN THE NEW SPC DAY 1 SLIGHT RISK COVERS MOST OF THE CWFA...WHICH MAY BE A TAD OVER DONE...AND THE FACT THE GENERAL THUNDER LINE EXTENDS WEST OF OUR CWFA...WILL GO AHEAD WITH SLIGHT CHANCE POPS ALL THE WAY THROUGH SE MISSOURI AS WELL. IF NOTHING ELSE...CONVECTION TO THE EAST COULD PRODUCE OUTFLOW WEST OF THE ACTUAL SYNOPTIC BOUNDARY AND PROVIDE ADDITIONAL SUPPORT FOR ISOLD TSRA. AM NOT SOLD WE WILL SEE ANYTHING WEST OF THE MISSISSIPPI AT THIS TIME...BUT INCLUDING A SLIGHT CHANCE POP SEEMS WARRANTED. KEPT A VERY SLIGHT CHANCE POP IN THROUGH THE EARLY EVENING...THEN DRY OVERNIGHT. THE FRONT WILL ALREADY BEGIN TO RETREAT NE AND OUT OF THE AREA BY MONDAY. NONE OF THE MODELS SUPPORT ENOUGH MOISTURE FOR CONVECTION AT THIS TIME INTO MONDAY. IF NOTHING ELSE...THE CHANCE IS AOB 10 PERCENT. NOT MUCH NEW TO REPORT FOR THE REST OF THE FORECAST. BUILDING UPPER RIDGE MEANS BACK TO THE HEAT TUESDAY AND WEDNESDAY. HEIGHTS ARE NOT FORECAST TO BE AS HIGH AS YESTERDAY. BUT MID 90S STILL LOOKS LIKELY. THE RIDGE IS FORECAST BY SEVERAL LONG RANGE MODELS TO BREAK DOWN THURSDAY AND BEYOND. WE WILL CONTINUE WITH OUR SMALL CHANCE POPS FOR SHOWERS AND THUNDERSTORMS IN THIS TIME FRAME. && .AVIATION... EARLY MORNING HAZE AND FOG WILL BURN OFF...THEN ATTENTION WILL TURN TO CONVECTIVE POTENTIAL. CLUSTERS OF STORMS THAT WERE NORTH OF KSTL AROUND SUNRISE WILL LIKELY PRODUCE OUTFLOW BOUNDARIES THAT WILL SERVE TO INITIATE NEW STORMS. ALTHOUGH THE EVOLUTION OF THIS PROCESS IS LIKELY TO BE HAPHAZARD...IT APPEARS THE HIGHEST POTENTIAL FOR CONVECTION WILL BE DURING THE AFTERNOON AND MORE TOWARD THE KEVV/KOWB TAF SITES. STORMS WILL DIMINISH WITH LOSS OF DAYTIME HEATING AFTER DARK. SOME LIGHT FOG IS AGAIN LIKELY TOWARD SUNRISE. && .PAH WATCHES/WARNINGS/ADVISORIES... KY...NONE. MO...NONE. IL...NONE.
