Area forecast discussion, Jun 20, 7:57 PM CST, 2 hours 49 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 957 PM EDT SAT JUN 20 2009 .UPDATE... INCREASED POPS A BIT UP UNTIL 06Z TONIGHT AS SHOWERS AND STORMS OVER THE IL/IN BORDER ARE PUSHING SE ALONG A RESIDUAL WARM FRONTAL BOUNDARY...WHERE DEWPOINTS SOUTH OF THE FRONT ARE IN THE MID 70S AND NORTH OF IT ARE IN THE UPPER 60S. THESE STORMS SHOULD SUSTAIN THEMSELVES INTO OUR CWA...WHERE GUSTY WINDS WILL BE THE MAIN THREAT. HOWEVER THINK MOST ACTIVITY SHOULD WANE AFTER MIDNIGHT...SO DO NOT HAVE POPS IN AFTER 2AM EDT. THE FRONT WILL SPLIT THE CWA OVERNIGHT THOUGH...SO A RENEGADE STORM ALONG IT IS NOT OUT OF THE QUESTION. ANOTHER MUGGY NIGHT IS ON TAP. UPDATE OUT SHORTLY. && .SHORT TERM (TONIGHT AND SUNDAY)... VISIBLE SATELLITE PICTURES INDICATED A FAIRLY NICE BOUNDARY FROM SOUTHERN ILLINOIS SOUTHEAST INTO CENTRAL KENTUCKY AT 18Z. ISOLATED LATE AFTERNOON AND EVENING THUNDERSTORMS WILL STILL BE POSSIBLE ALONG AND SOUTH OF THAT BOUNDARY SO WE WILL KEEP A MENTION OF STORMS IN THAT AREA THROUGH THE EVENING. THE SHORT RANGE MODELS ARE IN GOOD AGREEMENT ON BUILDING AN UPPER LEVEL RIDGE OVER THE EASTERN UNITED STATES TONIGHT AND MONDAY WHILE A DEEP TROUGH DEVELOPS JUST OF THE MID ATLANTIC STATES. ALTHOUGH WE WILL REMAIN IN A WEST TO NORTHWEST FLOW THE AFOREMENTIONED BOUNDARY WILL NOT MOVE THAT MUCH BUT BECOME MORE NORTHWEST TO SOUTHEAST ORIENTED SUNDAY. THE SREF ENSEMBLES INDICATED THE PROBABILITY OF STORMS DEVELOPING ALONG THIS AXIS AS VERY SMALL WHILE THE OPERATIONAL MODES INDICATE A MUCH BETTER CHANCE OF PRECIPITATION. SO WITH THIS IN MIND I WILL MENTION ISOLATED STORMS IN THE MORNING AND LOW CHANCE POPS DURING THE AFTERNOON. TEMPERATURES IN THE MORNING WILL BE SIMILAR TO THIS MORNING WITH THE EXCEPTION OF BWG WHERE THE LOW SHOULD BE A FEW DEGREES COOLER. HIGHS SUNDAY WILL WARM INTO THE UPPER 80S. .LONG TERM (SUNDAY NIGHT THROUGH SATURDAY)... VERY FEW CHANGES MADE TO ONGOING LONG TERM FORECAST. A LARGE RIDGE OF HIGH PRESSURE WILL REMAIN OVER THE CENTRAL PLAINS THROUGH THE PERIOD. THIS WILL BRING HOT TEMPERATURES TO THE AREA AND MAINLY DRY CONDITIONS. HOWEVER...A NORTH TO SOUTH ORIENTED BOUNDARY WILL REMAIN IN PLACE THROUGH MONDAY EVENING CREATING A FOCUSING MECHANISM FOR THUNDERSTORM DEVELOPMENT SUNDAY NIGHT AND MONDAY. INCREASED POPS TO AROUND 30 TO 40 PERCENT FOR THIS TIME PERIOD WITH SLIGHT CHANCE POPS MONDAY EVENING BEFORE DRYING THINGS OUT AS RIDGE BUILDS AND PUSHES THIS BOUNDARY EAST OF THE AREA. TEMPERATURES WILL RANGE FROM THE MID 80S...DEPENDING ON WHERE THERE IS MORE CLOUD COVER/PRECIPITATION TO THE AROUND 90 DEGREES ON MONDAY WITH OVERNIGHT LOWS SUNDAY NIGHT AND MONDAY NIGHT AROUND 70. SMALLER DISTURBANCES WILL ROTATE AROUND THE RIDGE AND INTO THE OHIO VALLEY ON TUESDAY BUT MAINLY EXPECT THAT THIS WILL JUST BRING SOME CLOUDINESS TO THE AREA. WEDNESDAY AND THURSDAY LOOK TO BE THE HOTTEST DAYS OF THE WEEK WITH HIGHS IN THE LOW TO MID 90S AND MOSTLY SUNNY SKIES. ON THURSDAY NIGHT AND FRIDAY...A TROUGH WILL MOVE ACROSS THE NORTHERN GREAT LAKES/SOUTHERN CANADA AND INTO NEW ENGLAND. THIS WILL DAMPEN THE RIDGE AND BOUNDARY WILL SAG SOUTHWARD TO AROUND THE OHIO RIVER BY FRIDAY MORNING. AT THIS TIME THERE ARE SIGNIFICANT DIFFERENCES IN THE LATITUDINAL PLACEMENT OF THIS BOUNDARY WITH THE ECMWF BEING FURTHER NORTH AND EAST AND KEEPING THE AREA MOSTLY DRY WHILE THE GFS IS FURTHER SOUTH AND BRINGS THUNDERSTORMS INTO SOUTHERN INDIANA AND NORTH CENTRAL KENTUCKY. DUE TO MODEL DIFFERENCES AND NO GOOD SIGNAL IN THE ENSEMBLE DATA HAVE DECIDED TO LEAVE THE FORECAST DRY AS WAS THE CASE IN THE PREVIOUS FORECAST TO WATCH MODEL TRENDS. THIS TREND CONTINUES INTO SATURDAY AND HAVE ALSO KEPT THIS PERIOD DRY FOR NOW AS WELL. EXPECT TEMPERATURES TO REMAIN IN THE UPPER 80S TO LOW 90S THROUGH THE END OF THE FORECAST PERIOD WITH OVERNIGHT LOWS IN THE UPPER 60S TO LOW 70S. LS && .AVIATION (00Z TAFS)... A WEAK FRONTAL BOUNDARY FROM NEAR OWB SOUTHEAST TOWARD SME WILL CONTINUE TO BE ORIENTED FROM NW TO SE ACROSS THE REGION THROUGH THIS 24-TAF PERIOD. ISOLATED SHRA/TSRA WILL CONTINUE ALONG THIS BOUNDARY AT LEAST THROUGH ROUGHLY 03Z...THOUGH THE ACTIVITY SHOULD WANE AFTER THAT FOR THE MOST PART. AFTER 12Z SUNDAY AND SOME HEATING TAKES PLACE...ISOLATED SHRA/TSRA WILL AGAIN BE POSSIBLE. TIME-HEIGHT CROSS-SECTIONS SUGGEST THAT THE BEST CHANCE FOR THIS WILL BE AT SDF...SO WILL CARRY VCTS THERE. MAY ALSO CARRY THIS IN LEX TOO...BUT BWG WILL REMAIN DRY. AS WITH ANY TS...BRIEF MVFR CIGS AND VSBYS WILL BE POSSIBLE. AFTER 12Z SUNDAY...SFC WINDS WILL BE MORE NWRLY THAN TODAY. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE. IN...NONE. && SHORT TERM...JA LONG TERM....LS AVIATION.....AL UPDATE.......AL
