MODELS AND WATER VAPOR SHOW A DEEP PROGRESSIVE 500MB TROUGH CURRENTLY MOVING ACROSS THE SOUTHERN PLAINS. THIS FEATURE IS FORECAST TO STEADILY MOVE EAST WITH ITS BASE CROSSING THE COMMONWEALTH LATE THURSDAY. LOW PRESSURE NOW OVER CENTRAL ILLINOIS IS FORECAST TO DEEPEN SLIGHTLY AND MOVE OVER THE DETROIT AREA BY THURSDAY MORNING. A SEASONALLY STRONG COLD FRONT WILL MOVE SOUTHEAST OF THE OHIO RIVER DURING THE PRE-DAWN HOURS TOMORROW. A LINE OF CONVECTION IS CURRENTLY BEGINING TO FORM JUST EAST OF A PSEUDO-DRY LINE/COLD FRONT ACROSS CENTRAL MISSOURI. THIS LINE IS EXPECTED TO INTENSIFY AND MOVE INTO OUR NORTHWESTERN COUNTIES AROUND 00Z THIS EVENING...THEN CROSS OVER OUR FORECAST AREA OVERNIGHT AND THEN EXIT THE BLUEGRASS AND LAKE CUMBERLAND REGIONS THURSDAY MORNING. ALTHOUGH THE BULK OF OUR PRECIPITATION WILL FALL OVERNIGHT...SOME SPRINKLES OR SCATTERED LIGHT SHOWERS WILL LIKELY MOVE INTO OUR WESTERN COUNTIES BY MID TO LATE AFTERNOON. CURRENT CLOUD COVER AND ONLY MARGINALLY STEEP LAPSE RATES WILL LIMIT THE INTENSITY OF THIS EXPECTED LINE OF CONVECTION AS IT APPROACHES LATE THIS EVENING. HOWEVER...INCREASING MOISTURE AND THE RELATIVELY SLOW MOVEMENT OF THE COLD FRONT WILL BRING SEVERAL HOURS OF MODERATE TO BRIEFLY HEAVY RAINFALL OVERNIGHT...WITH WIDESPREAD RAINFALL AMOUNTS OF AROUND ONE INCH EXPECTED. DESPITE THE WEAK INSTABILITY...ANY STORMS THAT CAN MIX DOWN STRONGER WINDS ALOFT MAY PRODUCE ISOLATED SEVERE WIND GUSTS. SHOWERS WILL BE ENDING ACROSS OUR EASTERN COUNTIES AROUND DURING THE MORNING HOURS. FEEL THAT ANY BRIEF SUNNY INTERVALS THAT DEVELOP TOMORROW MORNING WILL QUICKLY BE REPLACED BY WIDESPREAD STRATO-CU AS LOW LEVEL MOISTURE WRAPPING AROUND THE WESTERN SIDE OF THIS GREAT LAKES STORM ENCOUNTERS STEEPENING LOW LEVEL LAPSE RATES. INCREASING WINDS FROM THE WEST TOMORROW AFTERNOON COMBINED WITH EXPECTED HIGHS ONLY IN THE UPPER 50S WILL MAKE IT FEEL PRETTY RAW AND BLUSTERY. .LONG TERM (THURSDAY NIGHT - WEDNESDAY)...

NORTHWEST WINDS WILL CONTINUE WITH HIGHS STRUGGLING TO REACH 60 FOR A SECOND DAY IN A ROW. BY FRIDAY NIGHT UPPER LEVEL FLOW TRANSITIONS TO MORE ZONAL WITH HIGH PRESSURE DIRECTLY OVER THE REGION. MOSTLY CLEAR SKIES AND CALM WINDS WILL ALLOW FOR GOOD RADIATIONAL COOLING FRIDAY NIGHT INTO SATURDAY MORNING. WITH THIS TEMPERATURES WILL DROP TO NEAR THE DEWPOINTS IN THE MID TO LOWER 30S. IT LOOKS LIKE SOME PATCHY FROST WILL BE A DISTINCT POSSIBILITY ESPECIALLY OVER EAST CENTRAL KENTUCKY. THIS COULD POTENTIALLY CAUSE SOME DAMAGE TO EARLY BLOOMING VEGETATION. BY SATURDAY EVENING THE BUBBLE OF HIGH PRESSURE WILL MOVE EAST OF THE AREA AND RIDGING BUILDING IN ALOFT. THIS WILL ALLOW WINDS TO SHIFT TO A MORE SOUTHERLY DIRECTION. HIGH PRESSURE AND RIDGING ALOFT WILL REMAIN IN CONTROL OF OUR WEATHER THROUGH THE END OF THE LONG TERM. THIS WILL KEEP THE REGION DRY UNDER PARTLY TO MOSTLY SUNNY SKIES THROUGH WEDNESDAY. A GRADUAL WARM-UP WILL CONTINUE THROUGH MIDWEEK WITH HIGHS SUNDAY THROUGH WEDNESDAY RANGING FROM THE LOWER TO MID 70S...WELL ABOVE NORMAL.
