Area forecast discussion, Aug 18, 5:26 AM CST, 4 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 726 AM EDT WED AUG 18 2010 ...FORECAST UPDATE... HAVE ISSUED A FLASH FLOOD WARNING FOR THE LAKE CUMBERLAND REGION IN SOUTH CENTRAL KENTUCKY. TROPICAL MOISTURE IS STREAMING NORTHEAST ALONG A STALLED FRONTAL BOUNDARY THAT CURRENTLY STRETCHES FROM NEAR BOWLING GREEN THROUGH JACKSON KENTUCKY. DOPPLER RADAR ESTIMATED THAT BETWEEN 1 AND 3 INCHES OF RAIN HAD FALLEN SINCE 4 AM EDT ACROSS PORTIONS OF MONROE...CUMBERLAND...CLINTON...AND RUSSELL COUNTIES. ALTHOUGH RAIN MAY BECOME MORE SPORADIC ACROSS THIS AREA AFTER DAY BREAK...OCCASIONAL HEAVY DOWNPOURS ARE STILL EXPECTED THROUGH THE MORNING HOURS. ELSEWHERE...SUBSTANTIAL RAINS WILL CONTINUE ACROSS THE REST OF OUR SOUTHERN COUNTIES NEAR TENNESSEE AND ACROSS THE SOUTHERN BLUEGRASS REGION. .SHORT TERM (TODAY AND TONIGHT)... SHARP MOISTURE GRADIENT ACROSS THE CWA AT THIS TIME...WITH FRONTAL BOUNDARY ANALYZED FROM KENTUCKY MESONET DATA SOUTH OF AN OHIO TO LINCOLN COUNTY LINE. DEWPOINT DIFFERENCE BETWEEN KSDF AND KBWG IS 15 DEGREES THIS HOUR. WAVE OF RAIN WITH SOME EMBEDDED THUNDER IS MOVING ACROSS THE KY/TN BORDER. SOME WEAKER ECHOES OVER CENTRAL KENTUCKY ARE EVIDENCE OF OVERRUNNING WITH THIS BOUNDARY...AND MOST LIKELY NOT MUCH OF IT IS MAKING IT TO THE GROUND. THAT WILL CHANGE SOON. AS LOWER ATMOSPHERE MOISTENS UP TODAY...EXPECT A HEAVY RAIN EVENT FOR MOST OF SOUTH CENTRAL KENTUCKY. THE STALLED BOUNDARY WILL GET ENHANCED BY A SHORTWAVE TROUGH...NOTED ON LATEST WATER VAPOR IMAGERY OVER WESTERN MISSOURI AT THIS TIME. WHILE INSTABILITY WILL BE LIMITED BY CLOUD COVER...STILL EXPECT PLENTY OF DYNAMIC LIFT FOR MODERATE TO HEAVY RAINS TO FALL IN WAVES DOWN THERE. FLOOD POTENTIAL IS STILL IN QUESTION...SEE HYDROLOGICAL DISCUSSION BELOW. SIMILAR TO THE DEWPOINT GRADIENT...EXPECT A SHARP POP GRADIENT ACROSS THE REGION TODAY...WITH NORTHERN PARTS OF THE CWA BARELY IN THE SLIGHT CHANCE RANGE. THIS REGION WILL HAVE THE BEST CHANCE TO SEE INSOLATION TODAY...THOUGH LIKELY VEILED THROUGH MID TO HIGH CLOUDS. HAVE TEMPERATURES INTO THE MID 80S IN SOUTHERN INDIANA...THEN DROPPING OFF TO THE MID TO UPPER 70S ACROSS SOUTH CENTRAL KENTUCKY AND THE BLUEGRASS. .LONG TERM (THURSDAY - TUESDAY)... THE UPPER AIR PATTERN EARLY IN THE EXTENDED IS FORECAST TO FEATURE GENERALLY ZONAL FLOW ACROSS THE NORTHERN CONUS WITH A SERIES OF LOW AMPLITUDE TROUGHS TRAVERSING THE COUNTRY. BY EARLY THURSDAY MORNING ONE SHALLOW MID-LEVEL WAVE WILL BE MOVING EAST ACROSS THE CENTRAL APPALACHIANS AS ANOTHER WEAK FEATURE WILL CROSS THE CENTRAL ROCKIES. 500MB RIDGING WILL TRAVERSE THE LOWER OHIO VALLEY LATE FRIDAY AHEAD OF THIS SECOND FEATURE...NOW EXPECTED TO BE MOVING ACROSS THE MISSISSIPPI VALLEY. EXPECT PLENTY OF SUN AND WARMER AFTERNOON TEMPERATURES ACROSS SOUTHERN INDIANA AND ALONG THE OHIO RIVER THURSDAY AFTERNOON AS SUBSIDENCE DEVELOPS OVER ILLINOIS AND INDIANA. BY THURSDAY MORNING...THE BOUNDARY THAT HELPED PRODUCE TODAY'S RAIN ACROSS OUR SOUTHERN COUNTIES WILL HAVE SLIPPED FARTHER SOUTH ACROSS TENNESSEE AND SOUTHEASTERN KENTUCKY. MOISTURE LINGERING ACROSS THE LAKE CUMBERLAND AREA AND OUR TENNESSEE BORDER COUNTIES EARLY THURSDAY MORNING WILL PROBABLY LEAD TO A CLOUDY MORNING AND A SLIGHT CHANCE OF LINGERING SHOWERS. HOWEVER...EXPECT CLEARING ACROSS OUR SOUTH LATE IN THE DAY. AS MID LEVEL RIDGING ARRIVES THURSDAY NIGHT AND FRIDAY...EXPECT MOSTLY CLEAR SKIES WITH RELATIVELY LOW HUMIDITIES AND TEMPERATURES THAT WILL WARM BACK UP AT LEAST INTO THE LOWER 90S BY FRIDAY AFTERNOON. A TROUGH MOVING ACROSS THE WESTERN GREAT LAKES SATURDAY WILL SWEEP A COLD FRONT ACROSS ILLINOIS AND MICHIGAN LATE IN THE DAY. GULF MOISTURE OVER TENNESSEE AND THE NORTHERN GULF STATES WILL MOVE NORTH ON INCREASING SOUTHERLY FLOW SATURDAY. WILL NOT MAKE CHANGES TO CURRENT FORECAST OF A CHANCE OF CONVECTION CENTERED AROUND SATURDAY AFTERNOON AND EVENING. UPPER AIR PATTERN EARLY NEXT WEEK WILL BECOME MORE AMPLIFIED AND BLOCKY AS TROUGHS DEVELOP ACROSS THE PACIFIC NORTHWEST AND OFF THE MID ATLANTIC COAST. BOTH THE ECMWF AND THE GFS FORECAST A NARROW AMPLIFIED RIDGE EXTENDING FROM MISSOURI THROUGH WISCONSIN MONDAY. NORTHERLY FLOW ACROSS THE EASTERN OHIO VALLEY WILL SEPARATE A BUILDING DOME OF HOT AIR ACROSS THE LOWER MISSOURI VALLEY FROM COOLER TEMPERATURES ACROSS THE MID ATLANTIC. DEPENDING ON JUST HOW FAR EAST THIS EASTERN TROUGH SETS UP...HOT TEMPERATURES ARE LOOKING INCREASINGLY LIKELY ACROSS THE COMMONWEALTH SUNDAY THROUGH TUESDAY OF NEXT WEEK. EXPECT MOSTLY SUNNY SKIES FROM LATE SUNDAY THROUGH THE MIDDLE PORTION OF NEXT WEEK. && .HYDROLOGIC... OVER THE LAST 30 DAYS...SOUTH CENTRAL KENTUCKY HAS HAD RAINFALL ANYWHERE BETWEEN ONE AND FIVE INCHES ABOVE NORMAL. AN ADDITIONAL ONE TO THREE INCHES OF RAIN TODAY AND TONIGHT MAY CAUSE FLASH FLOODING...ESPECIALLY IN AREAS WHERE HEAVY RAIN BANDS SET UP AND TRAIN OVER THE SAME LOCATION. HOWEVER...FLASH FLOOD GUIDANCE VALUES INDICATE WE CAN HANDLE THIS MUCH RAIN. ONLY EXCEPTION MAY BE OVER THE LAKE CUMBERLAND COUNTIES...WHERE 6-HOUR GUIDANCE IS AT 1.5 INCHES. DO NOT HAVE HIGH ENOUGH CONFIDENCE IN PLACEMENT OF HEAVIEST RAIN BANDS AND/OR TRAINING TO GO WITH A WATCH EVEN THERE FOR NOW. WILL HAVE TO MONITOR LOCATIONS OF THESE BANDS FOR QUICK ISSUANCE OF FLASH FLOOD WARNINGS IF NECESSARY. WILL HIGHLIGHT THIS THREAT IN SEVERAL PRODUCTS AND OUR TOP NEWS. && .AVIATION (12Z TAF ISSUANCE)... UPSTREAM DEVELOPMENT CONTINUES FROM KBWG...SO WILL KEEP IN STORM CHANCES THROUGH MID MORNING WITH IFR TEMPO GROUP. EXPECT A BRIEF PAUSE IN HEAVIEST ACTION...TO ALLOW ATMOSPHERE TO DE-STABILIZE AGAIN WHICH WILL NOT TAKE LONG. SHOULD SEE ANOTHER ROUND OF STORMS IN THE EARLY AFTERNOON. MAY EVEN SEE ONE MORE ROUND LATE IN THE AFTERNOON BEFORE THE SHORTWAVE PROVIDING ALL OF THE EXTRA FORCING FINALLY SHIFTS EAST. STILL LOOKING GOOD AT KSDF...AS DRY AIR IS HOLDING TOUGH. LIGHT SHOWERS WILL CONTINUE TO PASS BY SOUTH OF THE AIRPORT AND MAY BE ABLE TO KEEP VFR THROUGH THE EVENING. MODELS INDICATE SOME LOW LEVEL MOISTURE STICKING AROUND TOWARD DAYBREAK AND PRODUCING REDUCED VSBY. SKIES SHOULD CLEAR BY MID MORNING. FOR KLEX...SIMILAR SITUATION AS KSDF WITH DRY AIR HANGING TOUGH. MAY GET SOME STORMS PASSING BY TO THE SOUTH. BEST BET NOW IS THAT THEY WILL JUST SEE SOME LIGHT RAIN. THEY TOO WILL GET SOME REDUCED VSBY'S TOWARD DAYBREAK THURSDAY. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE.
