The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Louisville, KY wrote its last area forecast discussion before the first event at Dec 9, 3:15 PM EST, 1 hour 47 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 315 PM EST SUN DEC 9 2007 .SHORT TERM (TONIGHT AND MONDAY)... QUASI-STATIONARY FRONT AND LOW PRESSURE WAVE ALONG IT CAUSING ALL SORTS OF PROBLEMS TODAY. THE FRONT IS CURRENTLY LOCATED FROM ROUGHLY OHIO COUNTY...TO FT. KNOX...TO JUST A HAIR NORTH OF FRANKFORT. THE LOW PRESSURE WAVE IS MOVING ACROSS OUR CWA CURRENTLY...CAUSING AMPLE SHOWERS WITH EMBEDDED THUNDERSTORMS MAINLY ALONG AND EAST OF I-65. RAINFALL AMOUNTS OF A HALF INCH OR MORE HAVE BEEN THE RULE...WITH A FEW MORE SITES EXPERIENCING OVER AN INCH OF RAIN TODAY. FEWER MORE SCATTERED SHOWERS ARE STILL FILTERING IN FROM THE WEST...WHICH ARE BEHIND THE FRONTAL BOUNDARY. IN ADDITION...THERE IS QUITE THE TEMP GRADIENT N AND S OF THE FRONT...LOW 40S N TO NEAR-RECORD HIGHS ACROSS SRN KY (70 AT BWG...RECORD HIGH 71). NAM12/GFS SHOW THAT THE FRONT WILL SAG SOUTHWARD TONIGHT AS THE LOW PRESSURE MOVES OFF TO THE NORTHEAST...MAKING THE FRONT LOCATED ROUGHLY FROM BWG TO LEX BY 06Z...AND ACROSS OUR FAR SERN CWA BY 12Z TOMORROW. ANOTHER WEAK WAVE OVER NE ARKANSAS CURRENTLY WILL MOVE ALONG THE FRONT NEWD...WHICH SHOULD BRING ANOTHER MAIN ROUND OF SHOWERS WITH EMBEDDED STORMS TONIGHT. A STRONG 925MB JET WILL HELP GENERATE THIS PRECIP AS IT OVERRUNS THE FRONT. SCATTERED SHRA AND DRIZZLE WILL BE POSSIBLE OTHERWISE. NAM BUFKIT PROGGED SOUNDINGS NORTH OF THE BOUNDARY TONIGHT INDICATE A VERY STRONG INVERSION AGAIN. CONFIDENT THAT DENSE FOG WILL OCCUR AGAIN TONIGHT...BUT ANY RAIN THAT OCCURS WOULD IMPROVE VSBYS QUICKLY...AND GIVEN THE UNCERTAINTY OF THE TIMING OF ANY PRECIP AND LOCATION OF THE FRONT...IT SEEMS TOO DIFFICULT TO PINPOINT THE BEST AREA FOR DENSE FOG. THINK IT WILL BE SOUTH OF THE OHIO RIVER...AND NORTH OF A LINE FROM BWG TO STANDFORD...OR ALONG AND ABOUT 50 MILES NORTH OF THE FRONT...MAINLY BETWEEN 03Z AND 12Z. HAVE AREAS OF DENSE FOG FOR OUR NORTH HALF...AND PATCHY DENSE FOG FOR THE SOUTH OVERNIGHT IN THE GRIDS. MAY GO WITH AN SPS FOR NOW TO GIVE A HEADS UP INSTEAD OF THE NPW. CONCERNING TEMPS...WILL BE A TIGHT GRADIENT ACROSS THE CWA TONIGHT. HAVE UPPER 30S N TO MID 50S SE. FOR MONDAY...FRONT WILL BE SOUTH OF THE CWA...WITH HIGH PRESSURE SLIDING EASTWARD ACROSS IL/IN. RIPPLES IN THE FLOW WILL CONTINUE CHANCES OF PRECIP TOMORROW...BUT KEPT ONLY LIKELY POPS TAPERING TO CHC BY 00Z TUES. NAM AND SREF HAVE AMPLE OVERRUNNING PRECIP...WHEREAS THE GFS GENERALLY HAS SCATTERED LIGHT PRECIP. TRENDED WITH THE NAM12 SINCE IT NAILED THIS AFTERNOONS PRECIP...THUS THE HIGHER POPS. FOR TEMPS...SHOULD BE A TIGHT GRADIENT AGAIN...WITH ONLY OUR FAR S/SE WITH MILD TEMPS...AND MUCH OF THE AREA IN THE 40S. .LONG TERM (MONDAY NIGHT THROUGH SUNDAY)... FIRST HALF OF THE LONG TERM PERIOD WILL FEATURE THE CLOSED UPPER LEVEL LOW OVER THE SW U.S. COAST. THIS FEATURE WILL HELP KEEP A SFC STATIONARY BOUNDARY ANCHORED FROM THE SOUTHERN PLAINS TO THE GRT LKS REGION THROUGH THURSDAY. THE UPPER LOW WILL THEN EJECT NEWRD THURS WITH AN ASSOCIATED SFC WAVE...CLEARING THE MIDWEST OF PRECIP AND ALLOWING A CANADIAN HIGH PRESSURE TO SETTLE IN FOR THE WEEKEND. TUESDAY THROUGH THURSDAY... EARLY TUESDAY THE SFC BOUNDARY WILL LIFT N OVER THE AREA AS A WEAK HIGH PRESSURE OVER THE GRT LKS MOVES E. THE SFC FRONT WILL SPREAD SCATTERED SHOWERS OVER THE AREA. NOT MUCH MID LEVEL ENERGY ASSOCIATED WITH THE FRONT AT THIS TIME AND WARM MID LEVELS WILL LIMIT LAPSE RATES...SO WILL ELIMINATE THUNDER FROM THE FORECAST AND HOLD ONTO RAIN SHOWERS. AS THE FRONT WILL LINGER JUST TO THE N OF FA IN THE AFTERNOON WILL KEEP LIKELY POPS OVER NRN FA...BUT WILL TAYLOR BACK POPS IN THE SRN FA. WINDS WILL TURN SRLY EARLY IN THE DAY ALLOWING STRONG WAA ADVECTION TO TAKE HOLD WARMING TEMPS UP WELL ABOVE NORMAL. DEPENDING ON HOW FAR NORTH THE FRONT STALLS OUT...WILL DETERMINE HOW MUCH WE WARM UP. RIGHT NOW...WENT FOR LOW 60S IN THE N FA TO LOW 70S IN THE S. WEDNESDAY THE FRONT WILL SHIFT BACK SWRD AHEAD OF AN APPROACHING SFC LOW THAT WILL TRACK UP THE FRONTAL BOUNDARY. HAVE LIKELY POPS WITH SLIGHT CHANCE THUNDER IN FOR WEDNESDAY AS THE FRONT WILL PROVIDE ENOUGH FORCING FOR SHOWERS. THUNDER IS STILL IN QUESTION DUE TO THE LACK OF INSTABILITY FOR WED...BUT WILL KEEP IN THE FORECAST FOR CONSISTENCY AT THIS POINT. COULD BE QUITE A TEMP GRADIENT OVER THE FA FOR WED DEPENDING ON FRONTAL LOCATION. HAVE A 10 DEGREE GRADIENT IN THE GRIDS RIGHT NOW...BUT THIS WILL NEED TO BE TWEAKED AS THE EVENT NEARS. A GOOD LLJ THURS MORNING WILL MAKE FOR GOOD TSRA CHANCES AS THE SHRT/WV AND ASSOCIATED MID LEVEL TROUGH MOVES NE UP THE FRONTAL BOUNDARY. EXPECT THIS SHRT/WV ENERGY TO BE N OF THE FA BY THURS AFTERNOON SO HAVE DECREASED POPS THURS AFTERNOON FROM W TO E. COOL AIR WILL START TO SPILL INTO THE AREA THURS BEHIND THIS FINAL WAVE PUTTING HIGHS IN THE UPPER 40S AND LOW 50S FOR THURS. FRIDAY THROUGH SATURDAY... CANADIAN HIGH PRESSURE WILL SPILL IN FROM THE NW FOR THE REMAINDER OF THE EXTENDED DRYING THE FA OUT...DECREASING CLOUD COVER...AND BRINGING COLDER TEMPS. A LONG WAVE TROUGH WILL DEVELOP OVER THE CONUS ALLOWING TEMPS TO COOL QUITE A BIT. HAVE TRENDED TEMPS DOWN IN THE EXTENDED WITH HIGHS IN THE 30S AND LOWS IN THE 20S BY THE WEEKEND. && .AVIATION (18Z TAFS)... ...SIGNIFICANT CIG/VSBY/WEATHER IMPACT TO AVIATION... LIFR TO SOMETIMES VLIFR CONDITIONS EXPECTED THROUGHOUT THIS 24-TAF PERIOD. WARM FRONT EXTENDING FROM NORTH OF BWG...TO JUST NORTH OF LEX IS STILL PUSHING SLOWLY TOWARD THE OHIO RIVER. CIGS AND VSBYS ALONG AND NORTH OF THIS BOUNDARY (SDF) WILL BE LIFR-VLIFR AT TIMES WITH NERLY WINDS...WITH POINTS SOUTH (BWG AND LEX) IN THE MVFR VSBY CATEGORY AND CIGS IN THE IFR/MVFR WITH WINDS OUT OF THE SOUTH. RAIN SHOWERS WITH EMBEDDED THUNDERSTORMS ARE AFFECTING MOST LOCATIONS ALONG AND WEST OF I-65...SO WILL CARRY TSRA OR SHRA VCTS WITH CB AT SDF AND BWG BETWEEN ROUGHLY 18Z AND 21Z...WITH A 1-2 HOUR LAG AT LEX. TOO DIFFICULT TO TIME OTHER PRECIPITATION IMPULSES...SO AFTER THAT...WILL LIKELY ONLY CARRY VCSH. VSBYS/CIGS WILL CONTINUE TO BE PROBLEMATIC AND LIFR OR WORSE AT SDF AND LEX AFTER 00Z...WITH POTENTIAL FOR DENSE FOG (VLIFR VSBYS). BWG SHOULD BE IN THE MVFR-IFR RANGE FOR CIGS/VSBYS AFTER 00Z. IF THE WARM FRONT SAGS AS FAR SOUTH AS BWG HOWEVER...WOULD HAVE WORSE CONDITIONS THERE THEN. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE.
