(ISSUED 250 AM EDT TUE SEP 12 2006) SHORT TERM (TODAY-TONIGHT)... PRONOUNCED INVERTED TROF LOCATED FROM WRN GREAT LAKES DOWN INTO LOWER MISS RIVER VALLEY AS OF 7Z. RADAR TRENDS SHOWING INCREASING COVERAGE OF SHRA AND EMBEDDED TS OVER NW 1/2 OF THE LMK CWA...WITHIN MOIST/WARM ADVECTION PATTERN. PW VALUES RUNNING ABOUT 130-150% OF NORMAL BASED OFF OF 0Z RAOBS AT ILN/OHX. HAVE LARGELY FOLLOWED 21Z/11 SREF DATA FOR THE FIRST 24-30 HOURS OF THE FCST. INVERTED TROF AND ASSOC UPPER WAVE FCST TO TRANSLATE EWD TOWARD THE CWA TODAY...AND THROUGH THE REGION TONIGHT. EXPECT PRECIP TO CONTINUE BECOMING WIDESPREAD THIS MORNING OVER SRN IND INTO PARTS OF CNTRL KY FROM SDF-BWG AS LOWER TROPOSPHERIC THETA-E RIDGE AXIS MOVES INTO THE REGION COUPLED WITH INCREASING LIFT. PRECIP OVER ERN 1/2 OF THE CWA FROM LEX DOWN INTO LAKE CUMBERLAND MAY REMAIN SCATTERED IN NATURE THIS MORNING AS LOW LEVEL THETA-E ACTUALLY DROPS AS WE APPROACH 12Z...BUT IT IS FORECAST TO INCREASE RAPIDLY BY 18Z AND AS SUCH WILL RAMP POPS UP QUICKLY TO CATEGORICAL BY THIS AFTN. AS SYSTEM MOVES TO THE EAST TONIGHT...AXIS OF HIGHEST PRECIP COVERAGE SHOULD ALSO CORRESPONDINGLY SHIFT EAST. FEEL THAT GIVEN SYSTEMS OVERALL CONFIGURATION (OPEN POSITIVELY TILED WAVE) THAT IT WILL MOVE RELATIVELY SLOWLY...SO WILL CONTINUE CATEGORICAL POPS THROUGH MIDNIGHT THEN SLOWLY DIMINISH AFTERWARDS...KEEPING CATEGORICAL IN THE ERN ZONES OVERNIGHT. NAM LOW LEVEL RH FIELDS INDICATING SCT-BKN STRATOCU OVERSPREADING THE CWA TONIGHT AS BOUNDARY LAYER WINDS TURN MORE WESTERLY. LOW STRATUS CURRENTLY BEING OBSERVED OVER MUCH OF MO/IA. PRIMARY CONCERN TODAY/TONIGHT IS WITH LOCALLY HEAVY RAINFALL...WITH 850MB/0-6KM WINDS ALIGNED NEARLY PARALLEL THROUGH AT LEAST 18Z INDICATING POTENTIAL FOR TRAINING...COMBINED WITH UNSEASONABLY MOIST AIRMASS. A NUMBER OF AREAS...WITH EXCEPTION OF FAR ERN PARTS OF THE BLUEGRASS...HAVE SEEN DECENT RAINS OVER THE PAST COUPLE DAYS...SO ANY ADDITIONAL HVY RAINFALL COULD RESULT IN LOCALIZED FLOODING ISSUES. WILL HIGHLIGHT HVY RAIN POTENTIAL IN ZFP/HWO. CLOUD COVER AND PRECIP SHOULD BE SUFFICIENT TODAY TO HELP HOLD MAX TEMPS DOWN...PLAN ON GOING BELOW MOS GUIDANCE FOR HIGHS...GENERALLY IN THE LOWER TO MIDDLE 70S. THIS SHOULD ALSO RESULT IN RELATIVELY LOW INSTABILITY VALUES AS A WHOLE...LIMITING SEVERE THREAT IN OUR DISTRICT. BEST THREAT LOOKS TO BE W/SW OF THE CWA BASED ON SIG SEVERE/WET MICROBURST PARAMETERS FROM THE 0Z NAM. STILL...A FEW STRONGER CELLS ARE POSSIBLE IF WE GET WARMER THAN FCST...WITH THE USUAL COMBINATION OF GUSTY WINDS/FREQ LIGHTNING ACCOMPANYING BURSTS OF HVY RAIN. CS LONG TERM (WEDNESDAY-MONDAY)... WEDNESDAY THROUGH THURSDAY NIGHT... 00Z WRF AND GFS RUNS ARE IN GOOD AGREEMENT ONCE AGAIN THROUGH THIS PERIOD OF THE FCST. BOTH MODEL SOLUTIONS SHOW UPPER LEVEL TROF OPENING UP AND HEADING EAST DURING THE DAY ON WEDNESDAY...WITH ASSOCIATED SFC COLD FRONT SLOWLY TREKKING EAST ACROSS THE REGION. AS SEEN IN THE PAST...OVERALL SYSTEM SPEED CONTINUES TO BE SLOWER WITH EACH MODEL RUN. THEREFORE...WEDNESDAY STILL LOOKS TO BE A MOSTLY CLOUDY DAY WITH SHOWERS AND STORMS ACROSS THE EASTERN HALF OF THE AREA. CURRENT FCST HAS THIS WELL IN HAND AT THE MOMENT. HAVE DECIDED TO UP POPS AGAIN FOR WED MORNING ACROSS THE EAST WHERE WE PLAN ON GOING WITH 80 POPS ONCE AGAIN. PRECIPITATION IS FCST TO END FROM WEST TO EAST BY WEDNESDAY EVENING. PLAN ON GOING WITH DRYING CONDITIONS ACROSS THE WEST AND CENTRAL SECTIONS WED EVE WITH A CHC IN THE EAST. ABUNDANT CLOUDS AND PRECIPITATION WILL KEEP A LID ON TEMPERATURES ONCE AGAIN. HAVE GONE CLOSER TO THE COOLER MAV MOS WITH HIGHS IN THE LOW 70S WEST AND UPPER 60S EAST. COOLER AND DRIER AIR WILL MOVE IN LATE WED NIGHT WITH OVERNIGHT LOWS IN THE UPPER 50S TO NEAR 60. AS FRONT AND UPPER LEVEL TROF DEPART...MODELS AGREE THAT DEEPENING H5 WAVE ACROSS WESTERN NOAM WILL INDUCE RIDGING ACROSS THE EASTERN THIRD OF THE NATION. AT THE SFC HIGH PRESSURE WILL HOLD SWAY YIELDING A SUNNY DAY AND CLEAR EVENING. HAVE GONE WITH A MET/MAV COMP FOR TEMPS THU. FRIDAY THROUGH MONDAY... LOOKING THROUGH THE EXTENDED...LATEST 00Z EXTENDED MODELS CONTINUE TO SHOW SIGNIFICANT H5 TROF DIPPING THROUGH THE PACIFIC NW AND THEN MOVING INTO THE PLAINS STATES LATE IN THE WEEKEND. THIS WILL BRING A DECENT LOOKING MID-LAT CYCLONE THROUGH THE PLAINS WITH A PERIOD OF ACTIVE WEATHER. SFC HIGH PRESSURE WILL HOLD SWAY THROUGHOUT THE WEEKEND WITH SOME INCREASE IN CLOUDS BY LATE SUNDAY. TEMPERATURES WILL START OFF COOL AT THE BEGINNING OF THE PD WITH A MODERATION IN TEMPS OCCURING THROUGH THE REMAINDER OF THE WORKWEEK. NEXT CHANCE OF PRECIPITATION LOOKS TO BE AROUND MONDAY AS UPPER LEVEL WAVE MOVES INTO THE GREAT LAKES AND DRAGS A SFC FRONT THROUGH THE REGION. GIVEN THE RECENT SLOWING TRENDS IN RECENT MODEL RUNS...WOULD NOT BE SURPRISED TO SEE PRECIP HOLD OFF UNTIL POSSIBLY TUE. PLAN ON TRENDING FCST TEMPS NEAR THE ENS MEANS ONCE AGAIN WHICH HAVE DONE WELL RECENTLY. -JARVIS && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE. IN...NONE. &&
