-- Changed Discussion --
(TODAY THROUGH WEDNESDAY) ISSUED AT 330 AM EDT TUE OCT 28 2014 RIDGING HAS SLID WELL OFF TO OUR EAST THIS MORNING AS A COLD FRONT IS STARTING TO ENTER THE OHIO RIVER VALLEY FROM THE CENTRAL PLAINS. AS THE FRONT APPROACHES FROM THE WEST TODAY...HIGH/MID CLOUDS WILL SLOWLY BE ON THE INCREASE THROUGH THE DAY. THIS EXTRA CLOUD COVER MAY KEEP TEMPERATURES A BIT COOLER TODAY...PREVENTING US FROM REACHING MORE RECORDS. HOWEVER...THE JACKSON RECORD IS ONLY 78...SO WE COULD COME CLOSE TO REACHING VALUE...BUT THE FORECAST WILL HAVE US FALLING SHORT BY A DEGREE OR TWO. THUNDERSTORMS HAVE BEEN FAIRLY PERSISTENT WITH THE COLD FRONT OVERNIGHT...SO THUNDER CHANCES LOOK DECENT LATER TODAY. IF WE CAN GET ENOUGH SURFACE INSTABILITY TO DEVELOP LATE IN THE DAY...WE COULD SEE A FEW STRONG THUNDERSTORMS. WINDS ALOFT ARE SUPPORTIVE OF A FEW WIND GUSTS UP TO 40 OR 50 MPH. SPC CONTINUES TO PAINT A 5 PERCENT AREA OVER CENTRAL KENTUCKY FOR THE POSSIBILITY OF A DAMAGING WIND GUSTS. GIVEN THE FORCING AND CONVERGENCE ALONG THE FRONT...PRECIPITATION LOOKS LIKE A SURE BET...SO HAVE INCREASED POPS LATE IN THE DAY THROUGH TONIGHT AS THE BOUNDARY PUSHES ACROSS THE AREA. MODELS HAVE SPED UP THE DEPARTURE OF THE PRECIPITATION LATE TONIGHT INTO EARLY WEDNESDAY...SO HAVE TRIMMED BACK POPS...ESPECIALLY WEDNESDAY MORNING. IN FACT...DRY AIR WILL QUICKLY ERODE THE SKY COVER...LEAVING A FAIRLY SUNNY DAY FOR WEDNESDAY. WHILE IT WILL BE COOLER BEHIND THE FRONT...HIGHS SHOULD BE ABLE TO RECOVER TO THE LOWER 60S...MAKING FOR A FAIRLY SEASONABLE DAY FOR MID FALL. .LONG TERM...(WEDNESDAY NIGHT THROUGH MONDAY) ISSUED AT 421 AM EDT TUE OCT 28 2014 SURFACE HIGH WILL CONTINUE TO BUILD INTO THE REGION WEDNESDAY NIGHT AS SHORTWAVE CONTINUES TO EXIT EAST. THIS WILL BRING MOSTLY CLEAR TO MOSTLY SUNNY CONDITIONS WEDNESDAY NIGHT INTO EARLY THURSDAY. HOWEVER CLOUDS WILL BE ON THE INCREASE LATER THURSDAY INTO THURSDAY NIGHT AHEAD OF NEXT SHORTWAVE. THIS SHORTWAVE WILL DIG SOUTH THURSDAY NIGHT INTO FRIDAY AND WILL BRING SLIGHT CHANCE POPS ACROSS NORTHERN AND EASTERN PORTIONS OF THE CWA AS WE MOVE INTO LATER FRIDAY INTO FRIDAY NIGHT. THE CLOUD COVER COULD KEEP SOME AREAS FROM MAXIMIZING RADIATIONAL COOLING FRIDAY NIGHT INTO SATURDAY MORNING. SATURDAY WILL BE COOL DAY ACROSS THE REGION AS AIRMASS USHERS IN HIGHS IN THE MID TO UPPER 40S TO EVEN LOWER 40S IN SOME SPOTS AS SURFACE HIGH CONTINUES TO BUILD EAST. MOVING INTO SATURDAY NIGHT SURFACE HIGH WILL CONTINUE TO CREST ACROSS THE REGION AS UPPER LEVEL RIDGE CONTINUES TO BUILD EAST. THIS WILL GIVE WAY TO CLEAR SKIES AND GOOD SETUP FOR RADIATIONAL COOLING WITH KILLING FREEZE STILL POSSIBLE. TEMPERATURES SATURDAY NIGHT WILL DROP INTO THE LOW 30S TO MID 20S ACROSS THE REGION. SUNDAY INTO MONDAY HIGH PRESSURE WILL MOVE OFF TO THE EAST ALLOWING TEMPERATURES TO MODERATE UNDER RETURN FLOW WITH TEMPERATURES BACK INTO THE LOWER 60S FOR HIGHS ON MONDAY.
