NWS Springfield, MO wrote its last area forecast discussion before the first event at May 24, 1:31 PM CST, 3 hours 9 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 231 PM CDT SUN MAY 24 2009 .DISCUSSION... BAND OF LIGHT TO MODERATE RAIN IS WRAPPING AROUND AN UPPER LOW OVER SOUTHERN ARKANSAS. RAINFALL RATES WITH THE ACTIVITY IN SOUTHERN MO HAVE BEEN JUST A FEW HUNDREDTHS OF AN INCH PER HOUR AT MOST. EXTENSIVE CLOUD COVER HAS LIMITED SURFACE HEATING IN ALL BUT WESTERN SECTIONS OF THE CWFA WHERE TEMPERATURES HAVE MADE IT INTO THE LOWER AND MIDDLE 80S. INSTABILITY SOMEWHAT HIGHER IN THESE AREAS...AND ARE SEEING SOME ISOLATED SHOWERS TRY TO DEVELOP. ALL IN ALL...HAS BEEN A QUIET WEATHER DAY WITH SO FAR. MAIN OVERALL CONCERN IS RAINFALL AND FLOOD POTENTIAL AS THE UPPER LOW NOW OVER SOUTHERN ARKANSAS LIFTS SLOWLY NORTH INTO SOUTHERN MO. MAIN PROBLEM IS THAT MOST MODELS HAVE OVERESTIMATED WHAT WAS EXPECTED TO HAVE OCCURRED SO FAR...AT LEAST THIS FAR NORTH. PWATS OFF THE 12Z KSGF SOUNDING WERE JUST UNDER 1.4 INCHES...A LITTLE LESS THAN RECENTLY PROGGED....BUT THE TREND TOWARD HIGHER OVERALL MOISTURE IS STILL EXPECTED AS THE UPPER LOW APPROACHES WITH PWATS REACHING THE 1.6-1.7 INCH NEIGHBORHOOD ON MEMORIAL DAY (SIMILAR TO LITTLE ROCKS 12Z SOUNDING). MAIN QUESTION IS WHERE THE HEAVIER RAIN WILL DEVELOP. STRONGER MOISTURE TRANSPORT OCCURRED LAST NIGHT AND THIS MORNING AS A LOW LEVEL JET WRAPPED AROUND THE NORTH AND NORTHWEST SIDE OF THE LOW OVER ARKANSAS...BUT THE GFS HAS BACKED OFF ON THE OVERALL MAGNITUDE OF THE MOISTURE TRANSPORT INTO SOUTHERN MO TONIGHT INTO MONDAY. A QUICK LOOK AT THE NEW ECMWF IS SOMEWHAT MORE BULLISH ON RAINFALL AMOUNTS VERSUS THE 12Z GFS. WILL CONSIDER A FLOOD WATCH TONIGHT THROUGH MONDAY OVER THE SOUTHERN MO OZARKS...BUT CONFIDENCE IS STILL FAIRLY LOW. UPPER LOW WEAKENS AND GETS CAUGHT UP IN THE MID LATITUDE FLOW BY TUE-WED. A WEAK SHORTWAVE AND BROAD SFC TROUGH/WEAK COLD FRONT MOVE THROUGH THE AREA WITH CONTINUED CHANCES FOR MAINLY DIURNAL CONVECTION WED-THU. HIGHER MID LEVEL HEIGHTS GRADUALLY BUILD EAST INTO THE AREA BEHIND THE EXITING SHORTWAVE LATE IN THE WEEK AND INTO NEXT WEEKEND WITH DRY WEATHER EXPECTED FRI-SUNDAY WITH SEASONABLE TEMPERATURES. DSA PREV UPDATE /1146 AM CDT SUN MAY 24 2009/ A BAND OF LIGHT TO MODERATE RAIN CONTINUES TO SLOWLY SHIFT NORTHWEST ACROSS SOUTH CENTRAL MISSOURI. THIS BAND IS NOT AS SOLID AS IT WAS EARLIER THIS MORNING...WITH BREAKS NOTED ON THE REGIONAL RADAR COMPOSITE. EXPECT THIS SLOW WEAKENING TREND TO CONTINUE AS IT APPROACHES THE INTERSTATE 44 CORRIDOR AROUND MID AFTERNOON. THERE HAS NOT BEEN A SINGLE LIGHTNING STRIKE WITH THIS ACTIVITY THIS MORNING...AND REALLY THINK LIGHTNING WILL BE LIMITED ACROSS SOUTH CENTRAL MISSOURI THIS AFTERNOON. HAVE THEREFORE GONE WITH ONLY AN ISOLATED THUNDER MENTION. A SLIGHTLY DIFFERENT SCENARIO IS EXPECTED NORTH OF THE INTERSTATE 44 CORRIDOR THIS AFTERNOON. THERE WILL BE A LITTLE MORE IN THE WAY OF INSTABILITY ACROSS THIS REGION...ALBEIT WEAKER THAN SATURDAY. DO THINK THERE WILL BE ENOUGH THERE TO CONTINUE CARRYING NORMAL THUNDER WORDING. LATEST SHORT TERM GUIDANCE INDICATES A BAND OF LOW LEVEL CONVERGENCE SLOWLY SHIFTING NORTHWEST ACROSS THE REGION...WHICH MAY PROVIDE SOMEWHAT OF A FOCUS FOR SHOWERS AND STORMS THIS AFTERNOON. DID DROP POPS ONE CATEGORY ACROSS CENTRAL MISSOURI AND WENT WITH SCATTERED MENTION FOR SHOWERS AND THUNDERSTORMS. WE ARE STILL LOOKING AT NON SEVERE THUNDERSTORMS ACROSS THIS REGION...WITH LOCALLY HEAVY RAINFALL BEING THE MAIN THREAT. OTHERWISE...THE REST OF THE FORECAST IS ON TRACK. PUBLIC PRODUCTS WILL BE UPDATED BEFORE NOON. SCHAUMANN && .AVIATION... A BAND OF LIGHT TO MODERATE RAIN WITH MVFR CONDITIONS CONTINUES TO SLOWLY APPROACH KSGF EARLY THIS AFTERNOON. THIS BAND WILL REACH KSGF AROUND MID AFTERNOON. MEANWHILE...SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON ACROSS THE REMAINDER OF SOUTHWEST MISSOURI. WILL COVER THIS WITH A TEMPO GROUP AT KJLN AND KSGF AS CONFIDENCE IN TIMING AND LOCATION IS NOT HIGH ENOUGH FOR PREVAILING. RAIN SHOWERS ARE EXPECTED TO PERSIST THIS EVENING AND WILL THEN INCREASE IN AREAL COVERAGE OVERNIGHT. CEILINGS AND VISIBILITIES ARE ALSO EXPECTED TO LOWER OVERNIGHT AS UPPER LEVEL LOW PRESSURE APPROACHES FROM THE SOUTH. KEPT CONDITIONS IN THE MVFR CATEGORY FOR NOW...BUT THERE WILL LIKELY BE POCKETS OF IFR AROUND...ESPECIALLY WITH HEAVIER SHOWERS. CONDITIONS SHOULD BEGIN TO IMPROVE BY LATER MONDAY MORNING. SCHAUMANN && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&
