AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 314 PM CDT WED SEP 1 2010 .DISCUSSION... /ISSUED 225 PM CDT WED SEP 1 2010/ FORECAST HIGHLIGHTS FOR THIS PACKAGE INCLUDE RAIN CHANCES THROUGH THURSDAY NIGHT AND A COOL DOWN FOR FRIDAY INTO THE UPCOMING WEEKEND. SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)... EPISODE OF HEAVY RAINFALL CONTINUES AT THIS HOUR. SUBSTANTIAL RAINFALL ACCUMULATIONS HAVE BEEN REPORTED ACROSS MUCH OF THE AREA. SEVERAL AREAS HAVE RECEIVED BETWEEN TWO AND FIVE INCHES OF RAIN...WITH ISOLATED REPORTS AS HIGH AS EIGHT INCHES. THE SOUTHEASTERN THIRD OF THE AREA HAS BEEN RELATIVELY UNTOUCHED SO FAR TODAY...THOUGH RADAR TRENDS INDICATE EXPANDING SHRA/TSRA... WHICH IS GOOD NEWS FOR THIS PARCHED AREA. THROUGH TONIGHT...MESOSCALE BOUNDARY EXTENDS FROM JUST NORTH OF BVO THROUGH FAR SOUTHERN MISSOURI (NEARLY COINCIDENT WITH THE MO/ARK STATE LINE) AT THIS HOUR. THERE ARE INDICATIONS OF THIS BOUNDARY AT BOTH THE SFC AND LOW LEVELS. IN THE LOW LEVELS... 925/850 MB WINDS OF 15 TO 20 KT REMAIN NEARLY PERPENDICULAR TO THE BOUNDARY...SHOWING SLIGHT SIGNS OF VEERING WITH TIME. THE AIRMASS REMAINS ANOMALOUSLY MOIST WITH PWS IN EXCESS OF TWO INCHES. MEANWHILE...A WEAK WAVE ALOFT IS MOVING SLOWLY TO THE NORTHEAST WITH TIME AS NOTED BY AREA PROFILERS AND RUC INITIALIZATIONS. HEADING INTO THIS EVENING...THE MORE INTENSE CONVECTION WILL BE JUXTAPOSED WITH THE LOW LEVEL BOUNDARY. CONVECTIVE ELEMENTS GREATER THAN 40 DBZ WILL RESULT IN INTENSE RAINFALL RATES...AS HIGH AS THREE INCHES PER HOUR AT TIME. FURTHER NORTH AWAY FROM THE BOUNDARY...RAINFALL BECOMES MORE STRATIFORM AS THE AIRMASS IS MUCH MORE STABLE. RAINFALL RATES ARE MUCH LOWER... THOUGH STILL RESULTING IN A LIGHT/MODERATE RAINFALL. EXPECT A SLOW DISSIPATING TREND FROM NORTH TO SOUTH ACROSS WEST CENTRAL MISSOURI...WITH A BAND OF RAINFALL BECOMING ORIENTED SW/NE ACROSS CENTRAL/SOUTHEAST PORTIONS OF THE CWA. A RISK FOR FLASH FLOODING CONTINUES IN AREAS THAT RECEIVED HEAVY RAINFALL TODAY. RAINFALL SHOULD TAPER OFF DURING THE OVERNIGHT HOURS. THURSDAY AND THURSDAY NIGHT...COLD FRONT OFF TO OUR NORTHWEST WILL BE OUR NEXT WEATHER MAKER. AFTER A BRIEF BREAK IN THE ACTION THURSDAY MORNING...THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG THIS COLD FRONT BY THE AFTERNOON. SHORT RANGE MODELS ARE A LITTLE FASTER WITH THE TIMING OF THIS FRONT WHICH WILL HAVE IMPACTS ON THE POTENTIAL FOR SEVERE WEATHER. SOUTHERLY FLOW WILL MAINTAIN A WARM/MOIST AIRMASS...WITH SOME SUNSHINE...TEMPS SHOULD WARM INTO THE MID/UPPER 80S. THIS WILL RESULT IN SBCAPE EXCEEDING 2000 J/KG AHEAD OF THE FRONT. WHILE THE MAIN BELT OF WESTERLIES...AND SHEAR...WILL RESIDE NORTH OF OUR AREA...LAPSE RATES WILL BE DECENT ENOUGH TO SUPPORT DAMAGING DOWNBURST WINDS WITH THE LINE OF STORMS AS IT MOVES INTO THE WESTERN CWA DURING THE MID AFTERNOON HOURS. THIS WIND RISK WILL PERSIST INTO THE EVENING ACROSS THE ENTIRE AREA AS THIS LINE WILL LIKELY TRAVERSE THE ENTIRE CWA. THE FRONT WILL CLEAR THE AREA BY DAYBREAK FRIDAY. GIVEN HEAVY RAINS FROM TODAY THERE IS A RISK FOR FLASH FLOODING WITH THE LINE OF STORMS ASSOCIATED WITH THE FRONT. GIVEN THE PROGRESSIVE NATURE OF THIS LINE...HAVE HELD OFF ON A FLOOD WATCH...THOUGH THIS MAY BE SOMETHING TO RECONSIDER TONIGHT. FRIDAY AND FRIDAY NIGHT...VERY PLEASANT AIRMASS WILL ENTER THE REGION. NORTHWEST WINDS WILL USHER IN COOLER TEMPERATURES AND DRIER AIR. TEMPERATURES WILL BE SEVERAL DEGREES BELOW AVERAGE UNDER A CLEAR SKY. THIS WILL SET THE STAGE FOR IDEAL WEATHER CONDITIONS THIS WEEKEND. GAGAN LONG TERM (SATURDAY THROUGH WEDNESDAY)... MED RANGE MODELS IN DECENT AGREEMENT FOR THE EXTENDED FORECAST. UPPER LEVEL TROUGH WILL DEVELOP OVER THE EASTERN CONUS WITH RIDGING OVER THE INNER MOUNTAIN WEST THROUGH THE UPCOMING WEEKEND. SURFACE HIGH PRESSURE WILL DOMINATE OUR WEATHER REGIME...WITH RATHER PLEASANT CONDITIONS EXPECTED. BOTH HIGH AND LOW TEMPERATURES WILL BE 7 TO 10 DEGREES BELOW AVERAGE WITH FULL SUNSHINE. THE UPPER TROUGH WILL SHIFT EASTWARD AND OVER THE REGION DURING THE FIRST HALF OF NEXT WEEK. SURFACE HIGH PRESSURE WILL SHIFT TO THE EAST COAST AND SOUTHERLY FLOW WILL RESULT IN AN INCREASE IN WARMTH AND MOISTURE. ABOVE AVERAGE HIGHS AND LOW ARE ON TAP...THOUGH THE ANOMALOUS STRENGTH OF THE RIDGING ALOFT SHOULD KEEP THE STORM TRACK FAR ENOUGH NORTH TO KEEP RAIN CHANCES LOW THROUGH THE MIDDLE OF NEXT WEEK. GAGAN && .AVIATION... /ISSUED 1241 PM CDT WED SEP 1 2010/ FOR THE 18Z TAF PACKAGE...PRIMARY FORECAST CHALLENGE CONTINUES TO BE HEAVY RAINFALL AND ASSOCIATED CIG/VIS RESTRICTIONS.
