AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 645 AM CDT WED SEP 16 2009 ...UPDATE TO AVIATION... .DISCUSSION... ...OVERVIEW... MAIN CONCERN WITH THE SHORT TERM WILL BE PRECIPITATION CHANCES OVER THE FAR SOUTHERN COUNTIES IN THE CWA. STRONG SYSTEM AND COLD FRONT EXPECTED TO ARRIVE IN THE LONGER TERM BY MONDAY AND STRONGER STORMS MAY BE POSSIBLE THEN. ...CURRENT CONDITIONS... COMPLICATED UPPER PATTERN WITH WEAK FLOW OVER MUCH OF THE CONUS AND A COUPLE OF SLOW MOVING UPPER LOWS AFFECTING AREAS FROM THE ROCKIES INTO THE MS VALLEY. LOW CURRENTLY AFFECTING WEATHER OVER THE CWA WAS LOCATED OVER SOUTHERN ARKANSAS EARLY THIS MORNING. DECENT SHORTWAVE WAS PUSHING SOUTH OUT OF THE GREAT LAKES AND INTO THE OHIO VALLEY THIS MORNING AND IS BRINGING DRIER AIR TO THE SOUTHWEST INTO THE REGION. ...SHORT TERM FORECAST... DRIER AIR WILL BE ADVECTING IN FROM THE NORTH-NORTHEAST TODAY AND WILL BATTLE THE MOISTURE TO THE SOUTH ASSOCIATED WITH THE LOW PRESSURE OVER ARKANSAS. WITH THE MOVEMENT TO THE SOUTH OF THE DRIER AIR...SHOULD SEE LESS COVERAGE OF PRECIPITATION TODAY...AND WILL BE MORE CONFINED TO AREAS ALONG THE MISSOURI ARKANSAS BORDER FOR MEASURABLE PRECIPITATION DURING THE SHORT TERM PERIOD. SHOULD BEGIN TO SEE LESS CLOUD COVER ACROSS THE NORTHERN CWA TODAY AND EVENTUALLY WORKING ITS WAY SOUTHWARD BY THE END OF THE SHORT TERM PERIOD. HIGH TEMPERATURES SHOULD GENERALLY BE IN THE UPPER 70S TO LOW 80S WITH LOWS FROM THE MID 50S TO LOW 60S. DEWPOINTS SHOULD BE ON THE DECREASE...ESPECIALLY IN THE NORTHERN CWA INITIALLY AS THIS DRIER AIR MASS MOVES INTO THE REGION. ...EXTENDED PERIOD... EYES WILL TURN TO SYSTEM PUSHING INTO THE PACIFIC NORTHWEST THIS WEEKEND. LATEST GFS DROPS THIS SYSTEM SOUTHEAST INTO THE CENTRAL PLAINS ON MONDAY AND CLOSES OFF A LOW. DECENT COLD FRONT DEVELOPS AND PUSHES THROUGH DURING THE DAY MONDAY. COULD SEE SOME STRONG TO SEVERE STORMS SHOULD CURRENT GFS SCENARIO PLAY OUT. HOWEVER...MODELS HAVE BEEN VERY INCONSISTENT IN THE EXTENDED LATELY SO WILL NEED TO MONITOR THIS FURTHER OVER THE NEXT COUPLE OF DAYS. LINDENBERG && .AVIATION... PILOTS FLYING IN AND OUT OF SPRINGFIELD AND JOPLIN AIRPORTS CAN EXPECT VFR CONDITIONS OVER THE NEXT 24 HOURS. HIGH LEVEL CLOUD COVER WILL CONTINUE TO HOVER OVER THESE AIRPORTS...AS MOISTURE CIRCULATES AROUND AN UPPER LEVEL LOW PRESSURE SYSTEM OVER SOUTHWEST ARKANSAS. NORTHEAST BREEZES COULD GUST IN EXCESS OF 20 MPH AT TIMES THIS AFTERNOON. THE BRANSON AIRPORT WILL EXPERIENCE SOME AVIATION CONCERNS REGARDING MVFR CEILINGS ALONG WITH CHANCES FOR LIGHT RAIN. A MODERATE TO HEAVY SHIELD OF RAIN WAS OBSERVED OVER NORTHERN ARKANSAS. A FEW STRAY SHOWERS ON THE NORTHERN PERIPHERY OF THIS SHIELD OF RAIN WILL IMPACT THE BRANSON AIRPORT...POTENTIALLY LEADING TO PERIODS OF MVFR VISIBILITIES.
