NWS Paducah, KY wrote its last area forecast discussion before the first event at Aug 27, 2:45 AM CST, 15 hours 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 345 AM CDT SUN AUG 27 2006 .DISCUSSION... TROPICAL MOISTURE IS WELL ENTRENCHED ACROSS THE LOWER OHIO AND MID MISSISSIPPI VALLEYS. PRECIPITABLE WATER ANALYSES AND MODEL FORECASTS INDICATE AT LEAST 2 INCHES IN THE COLUMN THROUGH MONDAY. LITTLE IN THE WAY OF FORCING WILL BE NECESSARY TO SUSTAIN CONVECTION OVER THE NEXT COUPLE OF DAYS. MAIN FORECAST CONCERNS ARE THE TIMING AND INTENSITY OF CONVECTION. THE PRIMARY FORCING FOR CONVECTION IS A FAIRLY HIGH AMPLITUDE 500 MB SHORTWAVE CURRENTLY OVER THE ROCKIES. THIS SHORTWAVE WILL MOVE RAPIDLY EASTWARD...ESPECIALLY RAPIDLY FOR THIS TIME OF YEAR. BY THIS EVENING...THE TROUGH AXIS WILL EMERGE OVER THE WESTERN HIGH PLAINS. MID LEVEL FLOW WILL TURN SOUTHWEST ACROSS THE LOWER OHIO VALLEY FAR IN ADVANCE OF THE TROUGH...WITH SOME EMBEDDED VORT CENTERS DEPICTED BY THE GFS. AS A RESULT...EXPECT SCATTERED CONVECTION TO INITIATE THIS AFTERNOON ALONG AND SOUTH OF A SYNOPTIC SCALE SURFACE FRONT OVER THE MID MISSISSIPPI VALLEY. THIS BOUNDARY...WHICH EXTENDED FROM NEAR KSPI TO KSTL TO KSGF AT 08Z...WILL MOVE LITTLE TODAY. THE GFS SEEMS A LITTLE MORE REALISTIC WITH ITS SEA LEVEL PRESSURE PATTERN...AND IT WILL BE THE MODEL OF CHOICE. THE NAM LOOKS UNREALISTIC SINCE IT DEPICTS SURFACE TROUGHS THAT HOPSCOTCH AROUND THE REGION. IN REALITY...NEITHER MODEL WILL BE ON TARGET SINCE CONVECTIVE SYSTEMS WILL PROBABLY WREAK HAVOC WITH SURFACE PRESSURES. ALTHOUGH NOCTURNAL COOLING WOULD NORMALLY FAVOR A DECREASE IN CONVECTION TONIGHT...THE MODELS AGREE ON THE DEVELOPMENT OF A WEAK LOW LEVEL JET THAT WILL LIKELY SUSTAIN ANY CONVECTIVE SYSTEMS THROUGH THE NIGHT. THIS WAS THE CASE FRIDAY NIGHT WITH A LOW LEVEL JET THAT SUSTAINED STORMS OVER THE PLAINS. LOCALLY HEAVY RAIN IS EASILY POSSIBLE DUE TO COPIOUS MOISTURE...RATHER SLOW MOVING STORMS...AND INCREASING UPPER SUPPORT FROM THE PLAINS SHORTWAVE. MONDAY INTO MONDAY NIGHT APPEARS THE MOST FAVORABLE TIME FRAME FOR CONVECTION AS THE SURFACE FRONT SAGS SOUTHEAST ACROSS THE LOWER OHIO VALLEY AND SOUTHERN MISSOURI. A STRING OF 500 MB IMPULSES WILL BE EMBEDDED IN SOUTHWEST FLOW ALOFT. ALREADY STRONG MOISTURE INFLOW WILL BE FURTHER ENHANCED BY WEAK SURFACE CYCLOGENESIS ALONG THE FRONT. SINCE THERE ARE STILL CONSIDERABLE TIMING DIFFERENCES BETWEEN THE MODELS...WILL OPT NOT TO INCLUDE HEAVY RAINFALL AMOUNTS AT THIS TIME. THE 00Z NAM IS SLOWER TO PUSH THE FRONT THROUGH...BRINGING IT ACROSS THE LOWER OHIO VALLEY TUESDAY MORNING. THIS IS ABOUT 12 HOURS SLOWER THAN THE 00Z GFS. SEVERE POTENTIAL APPEARS LIMITED BY EXTENSIVE MID AND HIGH CLOUDINESS THAT WILL LIKELY BE ASSOCIATED WITH WIDESPREAD TROPICAL CONVECTION. HOWEVER...DEEP LAYER SHEAR ASSOCIATED WITH THE MID LEVEL TROUGH WILL BE 20 TO 30 KNOTS...ENOUGH TO SUPPORT MULTI CELL CLUSTERS GIVEN ENOUGH INSTABILITY. POTENTIAL FOR ISOLATED SEVERE EVENTS WILL BE ADDRESSED IN THE HWO...ALONG WITH HEAVY RAIN POTENTIAL. THE FRONT WILL PROGRESS SOUTH OF THE KENTUCKY STATE LINE ON TUESDAY...FOLLOWED BY SURFACE HIGH PRESSURE MOVING ACROSS THE GREAT LAKES. A PERSISTENT FAIRLY STRONG NORTHEAST LOW LEVEL FLOW SHOULD LOWER HUMIDITY LEVELS DURING THE WEEK. NIGHT TIME LOWS WILL BE NOTICEABLY COOLER. THE 500 MB TROUGH IS EXPECTED TO STRENGTHEN OR CLOSE OFF OVER THE OHIO VALLEY BY THURSDAY...BUT THE DRY AIR MASS AND THE LACK OF ANY REAL COLD AIR ALOFT PRECLUDES MENTIONING PRECIPITATION AFTER WEDNESDAY. 500 MB TEMPS ARE FORECAST NEAR MINUS 10 THURSDAY...AND MID LEVEL LAPSE RATES WILL BE ONLY AROUND 5 C/KM. && .PAH WATCHES/WARNINGS/ADVISORIES...
