Area forecast discussion, Apr 30, 1:17 PM CDT, 5 hours 34 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 115 PM CDT WED APR 30 1997 INITIAL FORECAST PROBLEM IS COLD FRONT MOVING ACROSS MISSOURI AT 17Z. MORNING RAOBS AND RUC DATA INDICATE STRONG CAPPING OVER THE REGION SHOULD WEAKEN AS DAYTIME HEATING AND WARM MOIST ADVECTION CONTINUE. 700 MB COOLING IS PROGGED TO BEGIN LATE THIS AFTERNOON...WHICH WOULD ERASE THE CAP AROUND THE TIME OF FRONTAL PASSAGE. KLSX RADAR AT 18Z SHOWS INTENSE CONVECTION OVER NE MISSOURI. WILL HAVE TO MONITOR FOR MORE CONVECTION DEVELOPING SOUTHWARD THIS AFTERNOON AND EVENING. HIGHER CHANCE OF STORM DEVELOPMENT SHOULD BE TO THE NORTH...WHERE CAP IS WEAKER AND DYNAMIC FORCING WILL BE STRONGER. FRONTAL PASSAGE SHOULD BE AROUND 02Z AT KPAH AND 03-04Z AT KEVV. THIS SHOULD END THUNDERSTORM THREAT. COLD AIR ADVECTION BEHIND FRONT IS FAIRLY IMPRESSIVE. NGM BRINGS 850 ZERO DEGREE ISOTHERM DOWN TO KEVV BY 12Z THURSDAY. HOWEVER...THE ATMOSPHERE SHOULD REMAIN WELL MIXED AS BOUNDARY LAYER WINDS STAY AROUND 20 KNOTS OVERNIGHT. FWC AND FAN INDICATE UPPER 40S FOR LOWS TONIGHT...WHICH LOOKS REASONABLE. SURFACE HIGH PRESSURE WILL CROSS THE FA THURSDAY...ENDING THE COLD ADVECTION. NGM EVEN HINTS AT RETURN FLOW BY 00Z FRIDAY. TEMPS SHOULD RECOVER NICELY WITH STRONG SOLAR HEATING AND NEUTRAL TEMP ADVECTION. FAN/FWC HIGHS APPEAR IN THE BALLPARK. MY
