AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 1240 PM CDT SAT SEP 15 2012 ...UPDATE TO AVIATION... .UPDATE... HAVE MADE AN UPDATE TO POPS AND PRECIPITATION AMOUNTS FOR THE AFTERNOON PERIOD. A LOCALIZED BAND OF MODERATE RAINFALL WITH ACCUMULATIONS UP TO AROUND HALF AN INCH PER HOUR THAT CURRENTLY EXTENDS FROM AROUND JOPLIN TROUGH SPRINGFIELD AND EAST TOWARD HARTVILLE WILL CONTINUE TO PUSH TOWARD THE SOUTH AND EAST DURING THE AFTERNOON HOURS. SOME MINOR PONDING OF WATER CAN BE EXPECTED ON ROADWAYS...BUT NO FLOODING IS EXPECTED WITH THE RAINFALL AS THE SOIL REMAINS READY TO ABSORB LARGE AMOUNTS OF RAINFALL. KARDELL && .DISCUSSION... LIGHT RAIN WAS IMPACTING MUCH OF THE MISSOURI OZARKS AND SOUTHEASTERN KANSAS THIS MORNING IN RESPONSE TO AN AREA OF ISENTROPIC LIFT AND VERY LOW CONDENSATION PRESSURE DEFICITS CENTERED OVER THE AREA. THIS LIFT IS IN RESPONSE TO AN UPPER LEVEL TROUGH MOVING SLOWLY ACROSS THE PLAINS IN COMBINATION WITH A NEARLY STATIONARY INVERTED SURFACE TROUGH ACROSS EASTERN KANSAS AND OKLAHOMA. THESE FEATURES WILL REMAIN IN PLACE THROUGH MUCH OF THE DAY TODAY WITH DRIZZLE OR LIGHT RAIN AND SPRINKLES EXPECTED. WHILE RAINFALL AMOUNTS WILL BE LIGHT...PRECIPITATION SHOULD OCCUR THROUGHOUT THE DAY THOUGH PORTIONS OF CENTRAL MISSOURI MAY SEE THE BEST CHANCE FOR SOME DRY PERIODS. THE COMBINATION OF CLOUD COVER AND LIGHT RAINFALL WILL AGAIN KEEP TEMPERATURES ACROSS THE REGION FROM CLIMBING OUT OF THE 60S FOR THE MAJORITY OF THE AREA AND ONLY FALLING INTO THE 50S AGAIN TONIGHT. SIMILAR CONDITIONS WILL OCCUR SUNDAY AS THE UPPER TROUGH CONTINUES ITS SLOW PROGRESSION ACROSS THE AREA. CONDITIONS SUNDAY MORNING MAY ALSO BE ABLE TO ALLOW FOR SOME FOG DEVELOPMENT AS COOL AIR MOVES OVER A NOW MOIST GROUND. THE LIFT AND PRESSURE DEFICITS ARE NOT EXPECTED TO BE AS INFLUENTIAL HOWEVER AND MAY MAKE FOR LIGHTER OR MORE SCATTERED AREAS OF PRECIPITATION. THE DEVELOPING QUASI STATIONARY UPPER LEVEL LOW THAT IS TAKING UP SHORT TERM RESIDENCE OVER EASTERN CANADA WILL SWING ANOTHER SHORT WAVE AND ASSOCIATED COLD FRONT ACROSS THE PLAINS AND THE OZARKS MONDAY. MAINLY SHOWERS ARE EXPECTED THOUGH A FEW RUMBLES OF THUNDER COULD OCCUR. A COOL AIRMASS WILL FILTER INTO THE REGION BEHIND THIS FRONT ALLOWING OVERNIGHT TEMPERATURES TUESDAY MORNING TO FALL INTO THE 40S ACROSS THE AREA. A FEW LOW LYING AREAS MAY STILL SEE SOME UPPER 30S. THE UPPER LEVEL LOW OVER CANADA WILL THEN SWING ADDITIONAL UPPER LEVEL TROUGHS AND COLD FRONTS THROUGH THE PLAINS ABOUT EVERY 36 TO 48 HOURS THROUGH NEXT WEEKEND. IN GENERAL...THIS WILL KEEP THE REGION UNDER THE INFLUENCE OF UPPER LEVEL NORTHWESTERLY FLOW AND FALL LIKE CONDITIONS THROUGH THE UPCOMING WEEK. HATCH && .AVIATION... IFR CEILINGS WILL BE PERSISTENT ACROSS THE REGION OVER THE NEXT 24 HOURS. AN UPPER LEVEL TROUGH TO THE WEST WILL CONTINUE TO SUPPORT SOUTHERLY FLOW IN THE LOWER LEVELS THAT WILL KEEP MOISTURE FLOWING INTO THE AREA THROUGH THE OVERNIGHT HOURS AND INTO TOMORROW MORNING. SOME IMPROVEMENT CAN BE EXPECTED TOWARD MID DAY TOMORROW. KARDELL && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&
