NWS Jackson, KY wrote its last area forecast discussion before the first event at Aug 4, 6:13 AM EST, 1 hour 21 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 713 AM EDT MON AUG 4 2003 AFD IS DELAYED DUE TO ONGOING FLOODING PROBLEMS. .JKL...NONE. HAL --------------------------------------------------------------------- PREVIOUS DISCUSSIONS FOLLOW --------------------------------------------------------------------- 915 PM EDT SUN AUG 3 2003 AFTER NOT MUCH CONVECTION THROUGH THE AFTERNOON AND EARLY EVENING SOME THUNDERSTORMS HAVE FINALLY POPPED UP IN THE LAST HOUR. MSAS ANALYSIS SHOWING SOME WEAK SURFACE MOISTURE FLUX CONVERGENCE OVER ERN KY. WATER VAPOR HINTS AT VORT MAX MOVING ACROSS SOUTH CENTRAL KY...WHICH 18Z MESOETA FORECAST ALSO POINTS TOO. THUS SOME SUPPORT FOR SCATTERED CONVECTION TO CONTINUE FOR NEXT SEVERAL HOURS. CURRENT FORECAST LOOKS GOOD AND DO NOT PLAN AN UPDATE AT THIS TIME. SBH --------------------------------------------------------------------- 415 PM EDT SUN AUG 3 2003 18Z SFC ANALYSIS SHOWS A LARGE AREA OF LOW PRESSURE OVER THE MIDWEST AND OHIO VALLEY WITH A COLD FRONT STRETCHED BACK INTO EASTERN KANSAS. ON SATELLITE...THE DEEPER CLOUDS HAVE JUST ABOUT EXITED KENTUCKY TO THE EAST ALONG WITH THE REMAINS OF THE EARLIER MCS. JUST A SCATTERED CU FIELD EXISTS THROUGH KENTUCKY FURTHER WEST TO A NEW DEVELOPING MCS OVER WESTERN TENNESSEE. THE EARLIER RAIN AND CLOUD COVER HAS KEPT TEMPERATURES MAINLY IN THE 70S THROUGH EAST KENTUCKY AND ALSO HAMPERED CONVECTIVE REDEVELOPMENT WITH JUST A FEW SPOTTY LIGHT SHOWERS AROUND AT 3 PM. THE 12Z MODELS...FINALLY AVAILABLE IN AWIPS...ARE IN GOOD AGREEMENT WITH THE LONGWAVE PATTERN BUT DIFFER WITH THE TOUGHER DETAILS OF INDIVIDUAL SHORT WAVES. THEY ALL SPIN THE EVER PRESENT CLOSED UPPER LOW THROUGH THE UPPER MIDWEST AND NORTHERN OHIO VALLEY BY TUESDAY MORNING. IT OPENS UP BY MIDWEEK AND SLOWLY LIFTS INTO EASTERN CANADA LEAVING BEHIND A BROAD TROUGH OVER THE EASTERN HALF OF THE NATION THROUGH THE END OF THE WEEK. THIS WESTERN RIDGE AND EASTERN TROUGH PATTERN CONTINUES THROUGH THE WEEKEND WITH THE AXIS EDGING EAST OF THE APPALACHIANS. THE MAIN IDENTIFIABLE SHORTWAVE WILL SWING THROUGH HERE EARLY MONDAY WITH ADDITIONAL WEAKER AND HARDER TO TIME ONES CYCLING THROUGH BEFORE AND AFTER. ANOTHER GOOD ONE LOOKS TO GO THROUGH KENTUCKY WEDNESDAY. SENSIBLE WEATHER WILL FEATURE A LIKELY QUIET EVENING AWAITING THE NEXT MCS DEVELOPMENT. MAIN CONCERN FOR THIS WILL BE LATER TONIGHT SIMILAR TO THE ONE WE HAD THIS MORNING. DEPENDING ON THE AMOUNT AND COVERAGE OF ANY LATE NIGHT ACTIVITY ADDITION STORMS ARE A GOOD BET FOR MONDAY WITH THE UPPER LEVEL SUPPORT AND LEFT OVER CONVECTIVE BOUNDARIES. FOR THE REST OF THE WORK WEEK WILL RUN WITH DIURNAL CHANCES OF SHOWERS AND THUNDERSTORMS WITH A PEAK FOR THAT WAVE ON WEDNESDAY AND THEN LESSER SKY COVER/POPS LATER IN THE WEEK. WITH THE MAIN TROUGH AXIS SHIFTING EAST FOR SATURDAY AND SUNDAY WILL GO WITH AN OPTIMISTICALLY DRY FORECAST. TEMPS WILL BE SLIGHTLY BELOW NORMAL FOR HIGHS THROUGH THE PERIOD DUE TO THE CLOUDS AND PRECIPITATION. MOS TEMPS ARE SIMILAR THROUGHOUT THE PERIOD FOR LOWS...WILL NOT DEVIATE FAR IN THIS PERSISTENT PATTERN. AS FOR HIGHS...PREFER THE MIDDLE OF THE ROAD MAV NUMBERS FOR HIGHS MONDAY VERSES THE TOO WARM FWC AND TOO COOL MET. THE MET CONTINUES ON THE COOL SIDE FOR TUESDAY ...THE OTHER/S LOW 80S ARE MORE REASONABLE. AS FOR POPS...BIGGEST DISAGREEMENT IS WITH TONIGHT WITH THE FWC WAY TOO LOW AND THE MAV MORE REASONABLE. GOOD CHANCE LOOKS IN ORDER FOR MONDAY SIMILAR TO MAV AND FWC. AS FOR THE GFE GRIDS AND IFPS...GENERALLY JUST TWEAKED THE CURRENT GRIDS WITH LITTLE NEW...12Z...MODEL DATA AVAILABLE TO POPULATE WITH. KEPT THE IDEA OF COOLER MAXES FOR MONDAY WITH THE CLOUDS AND PRECIPITATION AROUND. OTHERWISE WENT WITH A DIURNAL TREND TO SKY AND POPS THROUGH FRIDAY WITH A DRIER WEEKEND.
