NWS Springfield, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 24, 2:45 PM CDT, 4 hours 4 minutes earlier.
Area forecast discussion, Jul 24, 2:45 PM CDT, 4 hours 4 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 245 PM CDT SAT JUL 24 2004 .DISCUSSION... A COMPLEX AND UNUSUAL PATTERN FOR LATE JULY ACROSS THE CENTRAL U.S. AN UPPER TROUGH CONTINUES TO SAG SOUTH INTO THE NORTHERN U.S. WHILE CANADIAN HIGH PRESSURE BUILDS SOUTH INTO THE UPPER MIDWEST. AN INVERTED SURFACE TROUGH HAD DEVELOPED NORTH INTO FAR SOUTHEAST KANSAS AHEAD OF A SLOW MOVING VORTICITY CENTRAL JUST EAST OF WICHITA. A SECONDARY WARM FRONT AHEAD DEVELOPED EAST OF THIS CIRCULATION ACROSS SOUTHERN MISSOURI. A STEADY RAIN CONTINUED NORTH OF THIS WARM FRONT IN AREA OF GOOD ISENTROPIC LIFT AND 850 MB MOISTURE CONVERGENCE. SHOWERS WERE SCATTERED IN THE PSEUDO WARM SECTOR. TEMPERATURES HAVE STRUGGLED TO RISE AND HAVE EVEN FALLEN NORTH OF THE FRONT ACROSS CENTRAL MISSOURI WHERE AFTERNOON TEMPERATURES WERE ONLY IN THE UPPER 50S THERE HAS BEEN SOME CONCERN ABOUT THE DEVELOPMENT OF LOW TOPPED SUPERCELLS IN THE WARM SECTOR OF FAR SOUTHWEST MISSOURI AND EXTREME SOUTHEAST KANSAS THIS AFTERNOON. CLEARING AND RESULTING INSTABILITY HAS BEEN LIMITED TO THIS POINT BUT SITUATION WILL BE MONITORED THE NEXT FEW HOURS. SEE THE PREVIOUSLY ISSUED DISCUSSION FOR DETAILS. THE VORTICITY CENTER AND MID LEVEL TROUGH AXIS WILL MIGRATE EAST SOUTHEAST TONIGHT AS THE SYNOPTIC SCALE TROUGH AXIS SWINGS SOUTHEAST. THE HEAVIEST AND MOST STEADY RAIN WILL OCCUR THIS EVENING IN AREA OF STRONGEST 850-700 MB MOISTURE CONVERGENCE/THETA-E ADVECTION AHEAD OF THE MID LEVEL TROUGH. DEEP SATURATED LAYER AND ISENTROPIC ASCENT WILL PERSIST AHEAD OF THE TROUGH. WIDESPREAD RAIN WILL PERSIST TONIGHT WITH THE STEADIEST RAINFALL ACROSS CENTRAL MISSOURI IN REGION BETTER ISENTROPIC LIFT. ANY THUNDERSTORMS THAT DEVELOP WILL END EARLY THIS EVENING. THIS SYSTEM WILL BE SLOW TO CLEAR OUT SUNDAY WITH CLOUDS LINGERING THROUGH THE DAY ACROSS MUCH OF THE FORECAST AREA. AREAS OF LIGHT RAIN WILL CONTINUE INTO THE MORNING BEFORE TAPERING OFF. A STEEPENING PRESSURE GRADIENT BETWEEN THE EXITING SURFACE TROUGH AND A LARGE PRESSURE SYSTEM DROPPING INTO PLAINS AND UPPER MIDWEST WILL CAUSE RATHER BRISK NORTHEAST WINDS FOR LATE JULY. HIGH TEMPERATURES WILL STRUGGLE TO RISE OUT OF THE 60S IF THE CLOUDS PERSIST. THE BELOW NORMAL TEMPERATURES WILL PERSIST INTO EARLY NEXT WEEK AS THE SURFACE HIGH BUILDS ACROSS THE REGION. HOWEVER MORE SUNSHINE WILL RETURN MONDAY ALLOWING TEMPERATURES TO RISE WELL INTO THE 70S. THE UPPER PATTERN WILL FLATTEN BY MIDWEEK IN THE WAKE OF THE DEPARTING TROUGH. INCREASING MOISTURE IN RETURN FLOW AND THE APPROACH OF A SHORTWAVE MAY BRING THE CHANCE OF SHOWERS BACK TO THE FORECAST AREA LATE WEDNESDAY AND THURSDAY. && .AVIATION... WIDESPREAD MVFR WILL CONTINUE THROUGH SUNDAY MORNING. CEILINGS WILL GENERALLY RANGE BETWEEN 1000 AND 2000 FEET. VISIBILITIES WILL LOWER TO BETWEEN 2 AND 4 MILES AT TIMES IN RAIN AND FOG. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. FOSTER
