NWS Springfield, MO wrote its last area forecast discussion before the first event at Jul 22, 1:44 PM CST, 5 hours 21 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 244 PM CDT THU JUL 22 2004 .DISCUSSION... ANOTHER HOT AND HUMID DAY IN PROGRESS ACROSS THE FORECAST AREA. LOOKS LIKE HEAT INDICES WILL TOP OUT NEAR 100 DEGREES. CONSIDERABLE AMOUNT OF CUMULUS HAD DEVELOPED DURING THE AFTERNOON. RUC ANALYSIS AND SOUNDINGS SUGGEST SURFACE BASED CAPES ARE GENERALLY NEAR 1500 J/KG BUT APPROACH 3000 ACROSS CENTRAL AND SOUTH CENTRAL MISSOURI. ALTHOUGH THERE APPEARS TO BE LITTLE IN THE WAY OF A CAP...THERE ARE NO DISCERNIBLE BOUNDARIES TO FOCUS CONVECTION UNTIL YOU GET INTO CENTRAL MISSOURI. THIS BOUNDARY STRETCHED FROM NEAR ST. LOUIS TO NEAR JEFFERSON CITY AND SEDALIA AT 18Z. AREAS NEAR THIS BOUNDARY AND EAST OF SPRINGFIELD APPEAR TO HAVE THE BEST CHANCE OF CONVECTIVE DEVELOPMENT THROUGH THIS EVENING. THE SYNOPTIC COLD FRONT WAS LOCATED FARTHER NORTH AND EXTENDED FROM SOUTHERN WISCONSIN INTO NEBRASKA. THIS FRONT WAS DROPPING SOUTH IN RESPONSE TO A UNSEASONABLY DEEP 500 MB TROUGH ACROSS CENTRAL CANADA. THESE FEATURES WILL BE THE PRIMARY WEATHER MAKES THE NEXT FEW DAYS. AS MENTIONED ABOVE THE OUTFLOW BOUNDARY WILL HAVE TO BE MONITORED FOR CONVECTIVE INITIATION THROUGH THE EARLY EVENING. OTHER STORMS WILL FORM FARTHER NORTH ACROSS NORTHERN KANSAS AND MISSOURI ALONG AND BEHIND THE COLD FRONT. CONVECTION WILL BE SUPPORTED BY DESCENT SYNOPTIC SCALE FORCING FOR MID SUMMER. PERSISTENT REGION OF UPPER LEVEL DIVERGENCE WILL BE MAINTAINED IN THE ENTRANCE REGION OF THE UPPER JET THAT WILL SAG SOUTH WITH TIME. THIS COMBINED WITH INCREASING MASS CONVERGENCE AT 850 MB WILL LIKELY FOCUS STORM DEVELOPMENT FROM NORTH CENTRAL KANSAS INTO NORTHWEST MISSOURI TONIGHT. THIS ACTIVITY WILL SAG SOUTH INTO THE OZARKS REGION LATE TONIGHT OR FRIDAY MORNING. SOME QUESTION AS TO HOW FAR SOUTH THE FRONT WILL MAKE IT ON FRIDAY. THE ETA BRINGS THE FRONT OR LEAST THE EFFECTIVE SURFACE BOUNDARY THROUGH THE FORECAST AREA FRIDAY MORNING WHILE THE GFS DEVELOPS A SURFACE WAVE AND STALLS THE FRONT ACROSS OUR NORTHERN COUNTIES. I WILL LEAN TOWARD THE ETA AS THE GFS APPEARS TO BE SUFFERING FROM SOME CONVECTIVE FEEDBACK. THERE IS SOME QUESTION ON THE EXTENT OF DESTABILIZATION THAT WILL OCCUR FRIDAY AFTERNOON BASED THE FRONTAL POSITION AND EXTENT OF CONVECTIVE DEBRIS CLOUDINESS. IN ANY CASE FRONTAL AND SYNOPTIC SCALE FORCING WILL LIKELY SUPPORT CONVECTIVE DEVELOPMENT THROUGH THE DAY. THE FRONT WILL TEMPORARILY STALL JUST TO OUR SOUTH FRIDAY NIGHT AS IT BECOMES PARALLEL TO THE FLOW ALOFT. INCREASING LOW LEVEL MOISTURE CONVERGENCE AND UPPER DIVERGENCE ALOFT WILL KEEP SHOWERS AND THUNDERSTORMS GOING FRIDAY NIGHT AND INTO SATURDAY MORNING. INCREASING CONCERN FOR FLOODING AS VERY MOIST LOW LEVEL AIRMASS WITH 850 MB DEWPOINTS NEAR 15 DEGREES CELSIUS WILL BE ADVECTED OVER THE SURFACE BOUNDARY AND PRECIPITABLE WATER VALUES ARE PROGGED TO BE IN EXCESS OF 1.75 INCHES. THIS VERY MOIST AIRMASS WILL BE EFFECTIVELY LIFTED IN FAVORABLE SYNOPTIC SCALE PATTERN. I WILL CONSIDER ISSUING A FLOOD POTENTIAL OUTLOOK. HOWEVER THE RISK OF FLOODING WILL BE HIGHLY CONDITIONAL BASED UPON RAINFALL THE NEXT 24 HOURS AND PLACEMENT OF CONVECTIVE COMPLEXES. DEEP LAYERED MOISTURE WILL REMAIN OVER THE AREA SATURDAY AND SATURDAY NIGHT AS THE TROUGH AXIS SAGS SLOWLY SOUTH. I HAVE INCREASED PRECIPITATION CHANCES AND CLOUD COVER THROUGH SATURDAY NIGHT. MUCH COOLER AIR WILL SPREAD INTO THE REGION BEHIND THE FRONT. HIGHS SATURDAY MAY STRUGGLE TO REACH THE LOWER 70S IF PRECIPITATION PERSIST. THE BELOW NORMAL TEMPERATURES WILL LINGER INTO EARLY NEXT WEEK AS AS STRONG CANADIAN HIGH PRESSURE BUILDS SOUTH. FOSTER && .AVIATION... HAZY CONDITIONS WILL PERSIST INTO THE AFTERNOON HOURS. VISIBILITIES WILL GENERALLY BE NEAR 6 MILES BUT LOCALIZED MVFR CONDITIONS NEAR 4 MILES CAN BE EXPECTED. ISOLATED THUNDERSTORMS WILL DEVELOP ACROSS CENTRAL AND SOUTH CENTRAL MISSOURI...BUT CONVECTION IS NOT EXPECTED AT THE SPRINGFIELD OR JOPLIN TERMINALS THROUGH THE AFTERNOON. THE CHANCE OF STORMS WILL INCREASE TONIGHT AND FRIDAY AS A COLD FRONT APPROACHES FROM THE NORTH. FOSTER && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. WFO SGF

OTHER SCATTERED THUNDERSTORMS WILL BE POSSIBLE LATER TONIGHT ACROSS THE ENTIRE OUTLOOK AREA. DISCUSSION: OUTFLOW BOUNDARIES FROM EARLIER THUNDERSTORMS ACROSS NORTHERN MISSOURI AND A COLD FRONT HAVE MOVED INTO CENTRAL MISSOURI LATE THIS AFTERNOON. SCATTERED THUNDERSTORMS HAVE DEVELOPED ALONG THESE FEATURES. THESE BOUNDARIES ARE FOCUSING THUNDERSTORMS DEVELOPMENT IN A MOIST AND UNSTABLE AIR MASS. ISOLATED SEVERE STORMS WILL BE POSSIBLE THROUGH MID EVENING ALONG THE BOUNDARY AS IT SLOWLY SAGS SOUTH. SCATTERED THUNDERSTORMS WILL BE POSSIBLE AREAWIDE TONIGHT AS A COLD FRONT AND UPPER LEVEL DISTURBANCE APPROACH THE REGION. THE BEST CHANCE OF STORMS WILL REMAIN ACROSS CENTRAL MISSOURI. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY. THUNDERSTORMS ARE EXPECTED FRIDAY INTO SATURDAY AS THE COLD FRONT MOVES ACROSS THE OUTLOOK AREA. THE POTENTIAL OF SEVERE WEATHER APPEARS TO BE LOW AT THIS TIME.
