NWS Jackson, KY wrote its last area forecast discussion before the first event at May 8, 6:44 PM EST, 3 hours 31 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 744 PM EDT SAT MAY 8 2010 .SHORT TERM.../THE REST OF TONIGHT/...UPDATED UPDATED THE FORECAST TO END THE LAKE WIND ADVISORY. WINDS HAVE FALLEN BELOW ADVISORY CRITERIA AND SHOULD CONTINUE TO DECREASE...ESPECIALLY AFTER SUNSET. STRATOCUMULUS CLOUDS HAVE MOVED INTO THE AREA. EXPECT THE CLOUDS TO DECREASE SOME AFTER SUNSET AS WELL. THE CLOUD COVER AND THE WINDS MAKE THE TEMPERATURE FORECAST FOR TONIGHT DIFFICULT. IF THE WINDS DIE DOWN ENOUGH...THE LOWER PORTION OF THE ATMOSPHERE MAY BE ABLE TO DECOUPLE. THEN IF THE CLOUDS DECREASE ENOUGH...FROST IN SOME OF THE DEEP VALLEYS IS NOT TOTALLY OUT OF THE QUESTION. HOWEVER BELIEVE THAT BETWEEN THE WINDS AND THE CLOUD COVER...THIS WILL NOT HAPPEN. THE PREVIOUS SHORT TERM FORECAST DISCUSSION FOLLOWS... /TONIGHT THROUGH MONDAY/ MODELS IN GOOD AGREEMENT THROUGH THE SHORT TERM. IN GENERAL...HIGH PRESSURE AT THE SFC AND SHORT WAVE RIDGING ALOFT WILL KEEP OUR WEATHER FAIR THROUGH THE PERIOD. ONLY EXCEPTION WILL BE VERY LATE IN THE PERIOD AS THE THREAT OF SHOWERS RETURN TO OUR SOUTHWESTERN ZONES LATE MONDAY AFTERNOON DUE TO A DEVELOPING WARM FRONTAL BOUNDARY. WITH THIS BEING AN OVERRUNNING EVENT...PREFERRED A FASTER SOLUTION WITH ONSET OF PRECIPITATION. OTHERWISE...BREEZY CONDITIONS CONTINUE AROUND STRONG LOW PRESSURE SYSTEM OVER THE GREAT LAKES REGION THIS AFTERNOON. WILL LET CURRENT NPW RIDE THROUGH 8 PM. OTHERWISE...WINDS DECREASE TONIGHT. HOWEVER... A LIGHT WEST NORTHWEST GRADIENT WIND ALONG WITH CU FIELD SHOULD HELP KEEP TEMPS UP AND FROST DOWN OVERNIGHT. REMOVED ANY MENTION OF FROST FOR TONIGHT. HIGH PRESSURE CENTERED MORE OVER OUR AREA FOR SUNDAY NIGHT...ESPECIALLY IN OUR EAST. WITH LIGHTER WINDS EXPECT MONDAY MORNING TEMPS MAY BE A TAD COLDER THAN TONIGHT. ALSO EXPECT THE THREAT OF PATCHY FROST TO BE A LITTLE GREATER AS WELL. HOWEVER...SOME MID LEVEL CLOUDS WILL BE ENCROACHING ON THE AREA SUNDAY NIGHT AS WELL. THIS COULD KEEP THE THREAT OF ANY FROST FROM DEVELOPING SHOULD THESE CLOUDS ROLL IN FASTER...AND WITH MORE SUBSTANTIAL COVERAGE. .LONG TERM.../MONDAY NIGHT THROUGH SATURDAY/ MOST DIFFICULT PART OF THE FORECAST IS TO PINPOINT WHERE A FRONTAL BOUNDARY WILL STALL OUT IN THE REGION AS THE FOCUS OF ANY RAIN AND POTENTIAL THUNDER NEXT WEEK WILL BE ALONG AND NEAR THE FRONT. LATEST MODEL RUNS ARE INDICATING THE UPPER RIDGE BUILDING OVER THE SOUTHEASTERN UNITED STATES WILL BE A BIT STRONGER...MEANING THAT THE FRONT WILL BE FURTHER NORTH AND A MUCH DRIER WEEK COULD BE IN STORE FORE EASTERN KENTUCKY THAN PREVIOUSLY ADVERTISED. HOWEVER...MANY ENSEMBLE MEMBERS ARE STILL SHOWING THE FRONT LINGERING ACROSS THE STATE OF KENTUCKY WHICH WOULD MEAN A VERY WET WEEK AS WAS THE CASE WITH MOST OF THE MODELS YESTERDAY. DECIDED TO TAKE A PERSISTENCE APPROACH WITH THE FORECAST AND LEAVE MOST OF THE GRIDS ALONE...UNTIL MODEL SOLUTIONS BEGIN TO LINE UP A BIT BETTER. THE MOST CHANGES IN THE FORECAST TODAY CAME IN THE FORM OF TWEAKING UP SOME LOW TEMPERATURES FOR THE MIDDLE OF THE WEEK TO LINE UP BETTER WITH NEIGHBORING OFFICES. && .AVIATION.../00Z TO 24Z/...UPDATED VFR CONDITIONS EXPECTED THROUGH THE PERIOD. A DECENT CU FIELD HAS DEVELOPED IN COLD AIR ADVECTION BEHIND DEPARTING COLD FRONT...BUT IS MOST PREVALENT FURTHER NORTH CLOSER TO THE MAIN STORM LOW. WINDS WILL CONTINUE TO BE BREEZY...GENERALLY 10 TO 15 KTS...BUT WITH OCCASIONAL JUMPS TO AROUND 20KTS DEFINITELY WITHIN THE REALM OF POSSIBILITIES. WINDS WILL DECREASE AS SUNSET APPROACHES...BUT REMAIN LIGHT OUT OF THE NORTHWEST THROUGH THE FORECAST PERIOD. && .JKL WATCHES/WARNINGS/ADVISORIES...NONE. && SHORT TERM...RAY/JJ LONG TERM....MACZKO AVIATION...JJ
