Area forecast discussion, Apr 11, 12:16 PM CDT, 1 hour 6 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 116 PM EDT FRI APR 11 2008 .MORNING UPDATE... A LINE OF THUNDERSTORMS IS MOVING TO THE NORTHEAST INTO THE COUNTIES NEAR AND SOUTH OF THE OHIO RIVER. THE STORMS CONTAIN VERY HEAVY RAIN AND A GOOD BIT OF LIGHTNING ALONG WITH GUSTY WINDS. THESE STORMS WERE PART OF A LONG LINE OF STORMS ALONG AND AHEAD OF A COLD FRONT THAT EXTENDED FROM CENTRAL ILLINOIS TO WESTERN KENTUCKY THEN SOUTH INTO TEXAS. HAVE INCREASED THE CHANCES OF RAIN THROUGH EARLY AFTERNOON FOR THE NORTHWEST PART OF THE FORECAST AREA. REST OF FORECAST REMAINS UNCHANGED. && .SHORT TERM (TODAY THROUGH SATURDAY)... ...SEVERE WEATHER THREAT TO CONTINUE THIS MORNING AND THEN ANOTHER SHOT OF SEVERE WEATHER AGAIN THIS AFTERNOON EAST OF I-65... 7Z RADAR TRENDS SHOWING STRONG STORMS OVER FORECAST AREA (FA) WITH A FEW SEVERE STORMS IN SOUTH CENTRAL KENTUCKY. EXPECT THE THREAT FOR SEVERE STORMS TO CONTINUE ALONG THE PREFRONTAL TROUGH MAINLY OVER THE KENTUCKY COUNTIES. THERE HAS ALSO BEEN SOME FLASH FLOODING AND SOME FLOOD ADVISORIES ISSUED OVER OUR SW INDIANA COUNTIES. EXPECT THAT ANY FLOODING THREAT IN THESE COUNTIES WILL SOON BE COMING TO AN END SOON HOWEVER AS STORMS ARE MOVING EAST OF THE AREA. THE CURRENT LINE OF STORMS SHOULD CONTINUE TO REMAIN STRONG THROUGH 12Z WITH A SLIGHT SEVERE THREAT TO CONTINUE. THE MAIN THREAT WOULD BE DAMAGING WINDS. THEN WE SHOULD HAVE A LULL IN ACTIVITY AFTER THIS LINE GETS THROUGH UNTIL THIS AFTERNOON. AS THE COLD FRONT APPROACHES...A NEW LINE OF STORMS IS EXPECTED TO DEVELOP THIS AFTERNOON ALONG THIS FEATURE. THERE IS A CHANCE THAT STORMS WOULD BE SEVERE...HOWEVER THIS SHOULD IMPACT MAINLY AREAS EAST OF I-65. THE MAIN THREAT FROM THESE STORMS WILL AGAIN BE DAMAGING WINDS ALTHOUGH MARGINALLY SEVERE HAIL IS POSSIBLE. THE FRONT SHOULD BE EAST OF THE FA BY 0Z TO 3Z TONIGHT ENDING PRECIP ALTHOUGH WINDS WILL REMAIN QUITE STRONG. COULD SEE GUSTS UP TO 35 TO 40 MPH THIS AFTERNOON AND EVENING. .LONG TERM (SATURDAY THROUGH THURSDAY)... PREVIOUS LONG TERM DISCUSSION WAS USED DUE TO ON-GOING SEVERE WEATHER: SATURDAY THROUGH MONDAY... MAIN CONCERN FOR THE LONGER TERM WITH SHOWERS OCCURRING IN THE MOISTURE WRAPPING AROUND THE UPPER LEVEL LOW THAT WILL SPREAD ACROSS SOUTH CENTRAL INDIANA AND CENTRAL KENTUCKY SATURDAY INTO MONDAY. AFTER THE COLD FRONT PUSHES THROUGH LATE FRIDAY AFTERNOON...COOLER AIR WILL BEGIN TO FLOW INTO THE LOWER OHIO VALLEY. IN ADDITION DRIER AIR WILL BRING A TEMPORARY END TO THE SHOWERS FOR PARTS OF FRIDAY NIGHT. EXPECT THE DRY SLOT TO REMAIN OVER MUCH OF THE AREA FRIDAY NIGHT AND INTO THE FIRST PART OF SATURDAY MORNING. HOWEVER AS THE UPPER TROUGH ROTATES SOUTH TOWARD THE OHIO RIVER SATURDAY MORNING...CLOUDS WILL INCREASE AND SCATTERED SHOWERS WILL ONCE AGAIN DEVELOP DURING THE AFTERNOON AND EVENING HOURS. THE SHOWERS WILL DECREASE SOME DURING THE OVERNIGHT HOURS BUT A SECOND TROUGH WILL TRIGGER AND INCREASE IN SHOWERS ON SUNDAY. THIS UPPER LEVEL SYSTEM WILL SLOWLY EXIT THE REGION ON MONDAY. TEMPERATURES ON SATURDAY WILL BE NOTICEABLY COOLER THAN FRIDAY/S MILD READINGS...WITH HIGHS ON SATURDAY ONLY IN THE LOWER AND MID 50S. BRISK NORTHWEST WINDS OF 15 TO 25 MPH WILL MAKE THE AIR FEEL EVEN COLDER. HIGH TEMPERATURES WILL HOVER AROUND 50 DEGREES AGAIN SUNDAY AND MONDAY WITH MORNING LOWS IN THE MID 30S. MONDAY NIGHT THROUGH THURSDAY... HIGH PRESSURE WILL BUILD INTO THE AREA MONDAY NIGHT AND TUESDAY AND WILL GRADUALLY TRACK EAST ACROSS CENTRAL KENTUCKY AND SOUTH CENTRAL INDIANA. THE HIGH WILL SETTLE OFF THE GEORGIA AND CAROLINA COAST ON THURSDAY AND THIS SHOULD KEEP THE LOWER OHIO VALLEY DRY FOR SEVERAL DAYS. TEMPERATURES WILL BE COOL THE BEGINNING OF THE WEEK WITH TEMPERATURES WARMING BACK INTO THE MID 60S TO LOWER 70S BY THURSDAY. && .AVIATION (18Z TAFS)... MAIN TAF CONCERN WILL BE THE CONVECTION THIS AFTERNOON AND TIMING THE COLD FRONT ACROSS THE AREA. THE MOST MOIST AND UNSTABLE AIR IS OR WILL BE ACROSS THE SOUTHERN PARTS OF CENTRAL KENTUCKY AND THIS COULD EXTEND UP TOWARD LEX LATER. SCATTERED SMALL CELLS CONTINUE BEHIND THIS AREA FROM NEAR SDF SOUTH TOWARD BWG. WILL KEEP MENTION OF THUNDERSTORMS IN FORECAST UNTIL AFTER A COLD FRONT MOVES THROUGH. AT 17Z COLD FRONT WAS NEAR A EVV TO HOP LINE WITH DEW POINTS LOWERING BEHIND THIS LINE. WINDS BECOME MORE WESTERLY OVER THE WESTERN PARTS OF THE STATE. MOST CIGS AND VSBYS WILL BE VFR ACROSS THE SOUTH WITH 2-3 THSD FOOT CIGS TO THE NORTH. FRONT SHOULD MOVE EAST OF TAF SITES BY 00Z WITH SKIES CLEARING WITHIN A FEW HOURS AFTER THE FRONTAL PASSAGE. AFTER A BREAK IN THE CLOUDS WRAP AROUND MOISTURE WILL ROTATE INTO THE AREA TOWARD THE END OF THE FORECAST PERIOD. EXPECT CIGS TO LOWET TO 2-3 THSD FT. && .LMK WATCHES/WARNINGS/ADVISORIES...
