NWS Jackson, KY wrote its last area forecast discussion before the first event at Jun 3, 2:25 PM EST, 2 hours 37 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON KY 325 PM EDT THU JUN 3 2010 .NEAR TERM.../TONIGHT THROUGH FRIDAY/...UPDATED 18Z SFC ANALYSIS SHOWS A QUASI-STATIONARY BOUNDARY LYING ACROSS THE NORTHWESTERN PORTION OF THE OHIO VALLEY INTO THE LOWER MISSISSIPPI VALLEY. AN MCV ROLLED EAST ALONG THIS FRONT EARLIER IN THE DAY WITH A CLUSTER OF SHOWERS AND THUNDERSTORMS. THIS ALL BYPASSED EAST KENTUCKY AND MAINLY LEFT A FAIR AMOUNT OF CLOUDS OVER OUR NORTHWEST COUNTIES INTO THE FIRST PART OF THE AFTERNOON. THESE HAVE JUST RECENTLY CLEARED ALLOWING UNFETTERED HEATING. ALSO IN THIS AREA...AN OUTFLOW BOUNDARY IS INDICATED THAT MAY LEAD TO CONVECTIVE INITIATION OVER THE NEXT COUPLE OF HOURS. ELSEWHERE DIFFERENTIAL HEATING AND CONVECTIVE TEMPERATURES BEING MET SHOULD INITIATE SCATTERED CONVECTION JUST ABOUT ANYWHERE THROUGH LATE AFTERNOON. THANKS TO A FAIR AMOUNT OF SUNSHINE TODAY...OUTSIDE OF OUR BLUEGRASS COUNTIES...TEMPERATURES HAVE REACHED INTO THE MID AND UPPER 80S WITH A FEW SPOTS HITTING 90 AS OF 3 PM EDT. MEANWHILE...DEWPOINTS ARE RUNNING IN THE MIDDLE 60S TO NEAR 70 DEGREES SUPPORTING A LARGE AMOUNT OF INSTABILITY. WHAT IS MISSING IS THE UPPER LEVEL SUPPORT THAT SEEMS TO HAVE LEFT THE AREA WITH THE MCV. STILL EXPECT SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP THROUGH EARLY EVENING EVEN WITHOUT THE HELP OF DECENT LEFTOVER BOUNDARIES OR UPPER LEVEL SUPPORT. BASICALLY ZONAL FLOW WILL CONTINUE ALOFT WITH ONLY VERY MINOR WAVES CROSSING THE OHIO VALLEY THROUGH FRIDAY...AS SEEN IN ALL MODELS. DIFFERENCES IN THE SOLUTIONS OVER THE NEXT 24 HOURS COME MAINLY FROM RESOLUTION DIFFERENCES AND PARAMETRIZATION OF EACH INDIVIDUAL MODEL RATHER THAN ANY NOTICEABLE DISAGREEMENTS ALOFT. AS SUCH...HAVE FOLLOWED A BLEND OF PERSISTENCE...THE NATURAL SUMMERTIME DIURNAL CYCLE...PATTERN PROPAGATION AND SOME ASPECTS OF THE NAM12 FOR SENSIBLE WEATHER IN THE NEAR TERM. EXPECT SCATTERED SHOWERS AND THUNDERSTORMS TO POP OVER THE AREA DURING THE NEXT COUPLE OF HOURS AND CONTINUE PROPAGATING FURTHER STORMS BASED ON INTERACTIONS OF THE BOUNDARIES FROM EARLIER STORMS. WITH CAPE PUSHING 3500 J/KG AND A LACK OF INHIBITION THESE ARE A GOOD BET. SPC AGREES AND HAS BOXED THE HIGHER THREAT AREA TO OUR SOUTHWEST. NEVERTHELESS...DO NOT ANTICIPATE ANYTHING TOO ORGANIZED TO JUSTIFY ANY MORE THAN SCATTERED COVERAGE THIS EVENING AND ISOLATED COVERAGE TONIGHT. WOULD NOT RULE OUT SEVERE THUNDERSTORMS EITHER...BUT THE BULK OF THEM WILL BE GARDEN VARIETY HEAVY RAINERS. WILL HAVE TO WATCH FOR MERGERS...THOUGH...AND WHETHER A COLD POOL CAN BE GENERATED FOR A BETTER SHOT AT SEVERE. FOR TONIGHT...ISOLATED SHOWERS AND THUNDERSTORMS WILL REMAIN POSSIBLE FOLLOWING THE LOSS OF HEATING. IN ADDITION...THE STANDARD AREAS OF PATCHY FOG WILL BE FOUND TOWARD DAWN WITH THE THICKEST SEEN IN PLACES THAT SEE RAIN. EXPECT SIMILAR CONDITIONS TO BE IN PLACE THROUGH THE AREA ON FRIDAY WITH THE BEST CONVECTIVE COVERAGE WAITING UNTIL LATE IN THE DAY WITH THE SUPPORT OF THE DAYTIME HEATING. SEE TEMPERATURES SIMILAR TO THOSE OF TODAY AS WELL AND HAVE DRAWN THE GRIDS AS SUCH. FOR TEMPERATURES...MAINLY FOLLOWED PERSISTENCE THROUGH FRIDAY. AS FOR POPS...ENDED UP CLOSEST TO THE MET NUMBERS. .SHORT TERM.../FRIDAY NIGHT THROUGH SATURDAY/...UPDATED FOR FRIDAY NIGHT THROUGH SATURDAY NIGHT...THE PATTERN WILL CONTINUE TO REMAIN SOMEWHAT STAGNANT. THE QUASI-STATIONARY BOUNDARY WILL SET UP AGAIN SATURDAY DRAPED ALONG THE OHIO RIVER NORTH AND LINE UP SOUTHWEST INTO THE MO...KY...AR...TN...AND IN NEIGHBORING STATES. COULD COVER WILL BE DEPENDENT UPON PREVIOUS DAYS ACTIVITY. ANY PREVIOUS OUTFLOW BOUNDARIES FROM FRIDAYS EXPECTED MCS WILL BE THE MAIN PROVIDER FOR CLOUD COVER AND THUNDERSTORM INITIATION. A WEAK DISTURBANCE WILL TRAVERSE THE STATIONARY BOUNDARY AGAIN DURING THE DAY ON SATURDAY. ONCE AGAIN...WITH WEAK UPPER LEVEL SUPPORT AND WEAK SURFACE GRADIENT WITH THE FRONT...DAYTIME CONVECTION AND INITIATION POINT WILL BE HEAVILY DEPENDENT ON DAYTIME HEATING AND PREVIOUS EVENING'S CONVECTION PROVIDING ANY PREEXISTING BOUNDARIES. ENERGY WILL MAKE IT TO THE EASTERN SLOPES SO OROGRAPHIC SUPPORT FOR INITIATION WILL HELP CONVECTION CONTINUE TO FLOURISH INTO SATURDAY EVENING. WITH INGREDIENTS BEING AVAILABLE...WHILE NOT SIGNIFICANT...WILL KEEP CHANCE POPS IN THE FORECAST. THERE IS A CHANCE THAT A FEW STORMS COULD GO SEVERE BUT WOULD NEED SOME MODIFICATION TO THE ENVIRONMENT FROM AN APPROACHING MCS. FOR TEMPERATURES...NAM SEEMS TO GO COOLER WITH MAX TEMPS ON SAT WITH THE GFS KEEPING IT UNUSUALLY WARM. WENT THE MIDDLE OF THE ROAD WITH MID 80S FOR HIGHS. .LONG TERM.../SATURDAY NIGHT THROUGH THURSDAY/...UPDATED THERE IS GENERAL MODEL AGREEMENT OF A CONTINUATION OF ZONAL FLOW ACROSS THE CONUS THROUGH THE EXTENDED PORTION OF THE FORECAST. A COLD FRONT WILL BE SLOWLY ENCROACHING FROM THE NORTH SATURDAY NIGHT WITH LIKELY MCS ACTIVITY ONGOING ALONG IT. BEST CHANCE OF CONVECTION WILL BE ALONG THE I-64 CORRIDOR. AS THE BOUNDARY MOVES THROUGH ON SUNDAY...MOST LOCATIONS WILL SEE A GOOD CHANCE OF CONVECTION. A FEW STORMS WILL LINGER IN THE SOUTHEAST EARLY SUNDAY EVENING...BEFORE RIDGING BRINGS A TEMPORARY DRY PATTERN TO THE AREA THROUGH MONDAY. ANOTHER WARM FRONT WILL DEVELOP IN THE PLAINS MONDAY NIGHT...AND WITH WNW FLOW ALOFT...WE WILL BE IN LINE FOR A THREAT OF MCS ACTIVITY. THIS THREAT WILL CONTINUE AT LEAST THROUGH WEDNESDAY...AS THE BOUNDARY BECOMES QUASI-STATIONARY NEAR THE AREA. THE FRONT FINALLY LOOKS TO MOVE THROUGH WEDNESDAY NIGHT. HAVE SIDED A BIT CLOSER TO THE ECMWF THAN THE GFS THIS FAR OUT WITH A SLIGHTLY SLOWER TIMING. FOR TEMPERATURES...GENERALLY STAYED CLOSE TO GUIDANCE FOR THE HIGHS...BUT WENT A BIT MORE DIURNALLY LIMITED ON SOME OF THE LOWS AS WE BECOME MORE ESTABLISHED IN THE WARM SECTOR. && .AVIATION.../18Z TO 18Z/ STILL AWAITING CONVECTIVE INITIATION ACROSS THE AREA THIS AFTERNOON. THE LATEST HRRR SHOWS THAT A FEW CELLS SHOULD START POPPING OVER THE NEXT TWO TO THREE HOURS WITH SCATTERED COVERAGE DEVELOPING. THE LATEST MESOSCALE ANALYSIS FROM SPC INDICATES THAT THE CONVECTIVE INHIBITION HAS BEEN LARGELY WORKED OUT AND ONLY REMAINS OVER A PORTION OF NORTH CENTRAL KENTUCKY. AS SUCH...HAVE MOVED THE VCTS GROUP TO AFTER 20Z AT ALL SITES WITH A SCATTERED CB LAYER AT 3500 FEET AND OVERCAST AT 6K FEET. WITH THE SCATTERED NATURE OF THE ANTICIPATED CONVECTION LATE THIS AFTERNOON AND EARLY EVENING...HAVE LEFT THE STORM FORECAST AS JUST VICINITY THROUGH 02Z. FOLLOWING THIS...EXPECT THE CLOUDS TO CLEAR AND ALLOW FOR PATCHY FOG IN THE MORE VALLEY LOCATIONS TOWARD DAWN RESULTING IN PREVAILING MVFR VIS AT SME AND LOZ. CONDITIONS WILL LIKELY BE WORSE AT ANY LOCATION TOWARD DAWN FRIDAY IF THEY MANAGE TO SEE ONE OF THE STORMS LATER TODAY. OTHERWISE...THE BR WILL BURN OFF BY 14Z FRIDAY WITH CB/S DEVELOPING TOWARD AFTERNOON...BUT COVERAGE OF ANY STORMS ARE EXPECTED TO BE TOO SPARSE TO WARRANT A VCTS IN THE TAFS UNTIL AFTER 18Z. WINDS THROUGH THE PERIOD...OUTSIDE OF ANY STORM...WILL BE LIGHT AND GENERALLY FROM THE SOUTHWEST. && .JKL WATCHES/WARNINGS/ADVISORIES...NONE. && NEAR TERM...GREIF SHORT TERM...SHALLENBERGER LONG TERM...GEOGERIAN AVIATION...GREIF
