NWS Springfield, MO wrote its last area forecast discussion before the first event at Jul 20, 1:52 PM CST, 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 252 PM CDT MON JUL 20 2009 .DISCUSSION... FORECAST CHALLENGES DEAL WITH HEAVY RAIN/SEVERE WEATHER POTENTIAL TONIGHT...FOLLOWED BY TEMPERATURES AND PRECIP CHANCES THROUGHOUT THE WEEK AS WE CONTINUE UNDER THIS NORTHWEST FLOW. SHORT TERM (TONIGHT THROUGH WEDNESDAY NIGHT)... CURRENTLY...SOME ISOLATED TO SCATTERED CONVECTION SEEN ON RADAR THIS AFTERNOON WHICH SEEMS TO CORRELATE WELL WITH BROAD UPGLIDE ALONG THE 310K ISENTROPIC SURFACE AND SEEMS TO BE HANDLED WELL ON THE WRF/NAM. BELIEVE THIS CONVECTION WILL REMAIN ACROSS OUR SOUTHERN COUNTIES THIS AFTERNOON. THE ECHOES BEING SEEN OUT WEST OVER SOUTHEAST KANSAS AND WESTERN MISSOURI SEEMS TO BE MAINLY ALOFT AS SURFACE OBSERVATIONS UNDER THE RETURNS ARE NOT REPORTING ANY RAINFALL. SURFACE ANALYSIS SHOWS A COLD FRONT ACROSS EASTERN NORTH DAKOTA...SOUTHWEST INTO SOUTHEASTERN WYOMING. THIS WILL BE THE SYSTEM TO MOVE THROUGH THE AREA ON TUESDAY. FOR TONIGHT...LOOKS LIKE THE MAIN SHOW BEGINS AFTER MIDNIGHT AS A CONVECTIVE COMPLEX FORMS OVER NORTHEASTERN KANSAS/SOUTHEASTERN NEBRASKA. LOW LEVEL JET OF 40-45KTS INCREASE ACROSS NORTHEAST OKLAHOMA AND SOUTHWEST MISSOURI AT THIS TIME AND FORCES TE REMNANTS OF A FRONTAL BOUNDARY NORTHEAST THROUGH THE CWA AHEAD OF THE COLD FRONT AS THE COMPLEX RIDES ALONG THE FRONT INTO MUCH OF THE CWA BY TUESDAY MORNING. COULD BE SOME CONVECTIVE CONTAMINATION WITH MODEL QPF OUTPUT...BUT IT DOES LOOK LIKE MOST COUNTIES IN THE CWA ARE GOING TO PICK UP QUITE A BIT OF RAINFALL WITH THIS SYSTEM AS IT MOVES THROUGH THE CWA. COMPLEX APPEARS TO BOW OUT ACROSS THE NORTHWESTERN CWA AS IT MOVES SOUTHEAST...SO WE MAY HAVE A PERIOD OF SEVERE WEATHER WITH STRONG WINDS BEING THE PRIMARY HAZARD...TURNING TO SOME FLASH FLOODING ISSUES AS THE COMPLEX MOVES THROUGH THE CWA. DUE TO THE RATHER QUICK MOVEMENT OF THE FORWARD PROPAGATING COMPLEX...DECIDED TO HOLD OFF ON A FLASH FLOOD WATCH. UPPER SHORTWAVE PICKS UP SURFACE LOW OVER WESTERN KANSAS OVERNIGHT AND MOVES THE LOW THROUGH SOUTHERN MISSOURI THROUGH THE SAY TUESDAY...ALONG WITH THE COLD FRONT. GOING TO BE A PRETTY DREARY DAY TOMORROW AS WRAP AROUND MOISTURE AROUND THE LOW KEEPS STRATUS CEILINGS AND LIGHT RAINFALL GOING THROUGH MOST OF THE DAY.GFS SHOWING 850MB TEMPERATURES AROUND +10C BEING DRAWN INTO MUCH OF THE CWA AROUND THE NORTHERN PART OF THE LOW...SO TEMPERATURES ARE REALLY GOING TO STRUGGLE TO EVEN GET TO BREAK 70 FOR MOST LOCATIONS. PRECIP SHOULD END BY LATE TUESDAY AFTERNOON INTO THE EVENING HOURS AS THE SYSTEM MOVES EAST. WE ARE STILL GOING TO BE TENDING WITH A COOL NORTHERLY FLOW AND PROBABLY SOME STRATUS INTO THE EVENING HOURS...SO TEMPERATURES ARE GOING TO BE WELL BELOW AVERAGE FOR THIS TIME OF YEAR INTO WEDNESDAY EVENING. CLAYCOMB LONG TERM (THURSDAY THROUGH MONDAY)... THE PERSISTENT NORTHWEST FLOW PATTERN WILL REMAIN THROUGH THE FORECAST PERIOD. THIS WILL ALLOW ANY SHORT WAVE...OR BIT OF ENERGY THAT ROTATES AROUND THE UPPER LEVEL LOW PARKED OVER THE GREAT LAKES...PRODUCE PRECIPITATION ACROSS THE REGION. THUS WILL CONTINUE PRECIP CHANCES NEARLY EACH DAY THROUGH MONDAY OF NEXT WEEK. THE NICE PART WILL BE THE UNSEASONABLE COOL TEMPERATURES THAT WILL REMAIN FOR THE OZARKS AS A RESULT OF THE NORTHWEST FLOW. EXPECTING TEMPERATURES TO SEE SEVERAL REINFORCING SHOTS OF COOL AIR AS AFOREMENTIONED BITS OF ENERGY ROTATE AROUND THE UPPER LOW. BECAUSE OF THIS...WENT GENERALLY BELOW GUIDANCE FOR TEMPS THROUGH THE PERIOD AND EXPECT A NICE WEEKEND AND START TO THE WEEK NEXT WEEK. THE BEST CHANCES OF RAINFALL FOR THE EXTENDED LOOK TO COME FRIDAY NIGHT INTO SATURDAY MORNING AS A FAIRLY STRONG COLD FRONT...FOR THIS TIME OF YEAR...SWINGS THROUGH THE OZARKS. TIMING OF THE FRONT AT THIS POINT IS THE QUESTION THOUGH AS ECMWF IS A BIT SLOWER THAN THE GFS WHICH COULD LINGER RAINFALL INTO LATER IN THE DAY SATURDAY. HATCH && .AVIATION... FOR THE 18Z TAFS...VFR FLIGHT CONDITIONS THIS AFTERNOON WILL GIVE WAY TO DETERIORATING FLYING WEATHER THIS EVENING AS A COLD FRONT APPROACHES FROM THE NORTHWEST. CONDITIONS NORMALLY SEEN IN A LATE FALL/WINTER PATTERN WITH IFR CONDITIONS AND NORTHWEST FLOW WILL CREATE UPSLOPE CONDITIONS FOR THE SGF AND JLN TAFS. AHEAD OF THIS FRONT...WINDS WILL BE FAVORABLE FOR MOISTURE POOLING IN THE WHITE RIVER VALLEY THAT COULD BRING BRING CEILINGS DOWN AT BBG EARLY TUESDAY MORNING. CONDITIONS AT BBG COULD REACH FIELD MINS AS THE MORNING PROGRESSES. CLAYCOMB && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&
