Area forecast discussion, Jul 19, 2:05 AM CST, 55 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 305 AM CDT SAT JUL 19 2003 .DISCUSSION... THUNDERSTORMS CONTINUE TO REDEVELOP ACROSS SOUTH CENTRAL MISSOURI EARLY SATURDAY MORNING. HOWEVER AN OVERALL WEAKENING TREND HAS BEEN NOTED. STORMS WERE SUPPORTED BY STRONG WARM AIR ADVECTION ON THE NOSE OF A MODEST LOW LEVEL JET. THIS JET WAS INTERSECTING AN OUTFLOW BOUNDARY THAT WAS MIGRATING WEST ACROSS SOUTHWEST MISSOURI...AND WAS LOCATED JUST WEST OF SPRINGFIELD AS DEPICTED BY 8-BIT RADAR IMAGERY. LARGE HAIL HAS BEEN THE PRIMARY HAZARD THROUGH THE NIGHT WITH ROTATING STORMS SUPPORTED BY MODERATE 0-6 KM SHEAR OF NEAR 40 KTS. LAPS SOUNDING DATA SHOWS THE CAP HOLDING STRONG ACROSS SOUTHWEST MISSOURI AND SOUTHEAST KANSAS. FLASH FLOODING HAS ALSO BEEN AN INCREASING CONCERN AS CELLS TRAIN ACROSS THE SAME AREAS OF SOUTH CENTRAL MISSOURI. SHORT TERM (TODAY THROUGH SUNDAY)... CONVECTION WILL CONTINUE THROUGH THE EARLY MORNING THEN GRADUALLY DIMINISH DURING THE MORNING AS THE LOW LEVEL JET WEAKENS. EFFECTIVE BOUNDARY WILL TRANSITION SOUTHWEST AND SET UP ACROSS FAR SOUTHWEST MISSOURI THIS AFTERNOON. WEAK CONVERGENCE ALONG THE BOUNDARY AND MODERATE TO STRONG INSTABILITY WILL SUPPORT SCATTERED THUNDERSTORM DEVELOPMENT THIS AFTERNOON. MID LEVEL WARM LAYER AND CONVECTIVE INHIBITION WILL BE LIMITING FACTORS TO WIDESPREAD STORM COVERAGE. HOWEVER ISOLATED SEVERE STORMS POSSIBLE GIVEN THE DEGREE OF INSTABILITY AND STEEP MID LEVEL LAPSE RATES. NOT A STRONG INDICATION OF DEVELOPMENT TONIGHT AND WILL ONLY MENTION ISOLATED EVENING ACTIVITY. NEXT SUBSTANTIAL SHORTWAVE RIDING THROUGH THE NORTHWEST FLOW WILL APPROACH THE REGION LATE SUNDAY. STRONG INSTABILITY AND RATHER STEEP LAPSE RATES WILL AGAIN SUPPORT ISOLATED SEVERE STORMS. IT APPEARS CONVECTION WILL CONTINUE AND EVEN ORGANIZE INTO SUNDAY NIGHT AS WARM LEVEL ADVECTION INCREASES. EXCESSIVE HEAT AND HUMIDITY WILL ALSO BE A CONCERN THIS WEEKEND. WILL CONTINUE WITH HEAT ADVISORY TODAY ACROSS SOUTHWEST MISSOURI AND EXTREME SOUTHEAST KANSAS. I HAVE RAISED TEMPERATURES SOME AS AREA WILL SEE A WARM START. POOLING DEWPOINTS ALONG THE BOUNDARY WILL PUSH HEAT INDICES OVER 105 NEAR THE KANSAS BORDER WITH SOME LOCATIONS NEAR 110 DEGREES. I HAVE NOT EXTENDED THE ADVISORY INTO SUNDAY BUT WILL TAKE A CLOSER LOOK THIS MORNING. LONG TERM (MONDAY THROUGH FRIDAY)... UPPER PATTERN WILL AMPLIFY INTO EARLY NEXT WEEK WITH NORTHWEST FLOW ACROSS THE REGION. A SHORTWAVE WILL BRING A FRONT ACROSS THE REGION MONDAY WHICH WILL ALLOW SLIGHTLY COOLER AND DRIER AIR TO INFILTRATE THE REGION. SEASONABLE TEMPERATURES AND LESS HUMID CONDITIONS WILL PREVAIL THROUGH THE MIDDLE OF NEXT WEEK. && .AVIATION... EXPECT MAINLY VFR CONDITIONS AT JOPLIN (KJLN) AND SPRINGFIELD (KSGF) AS MOST OF THE THUNDERSTORMS REMAIN FARTHER EAST ACROSS SOUTH CENTRAL MISSOURI. GREATEST CONCENTRATION OF STORMS WILL BE NORTHEAST AND EAST OF SPRINGFIELD (KSGF). LOWEST CEILINGS WILL BE IN TWEB ROUTE 233 FROM KSTL-KSGF WHERE SCATTERED MVFR AND LOCALIZED IFR CONDITIONS CAN BE EXPECTED THIS MORNING. CONDITIONS WILL IMPROVE AREA WIDE DURING THE MORNING AS STORMS GRADUALLY DISSIPATE. HOWEVER ISOLATED THUNDERSTORMS WILL AGAIN DEVELOP THIS AFTERNOON AND EVENING. && .SGF WATCHES/WARNINGS/ADVISORIES... .MO...HEAT ADVISORY ALONG AND WEST OF A LINE FROM CASSVILLE TO LAMAR TO VERSAILLES THROUGH 11 PM SATURDAY. .KS...HEAT ADVISORY ALL ZONES THROUGH 11 PM SATURDAY.

DISCUSSION: A COMPLEX OF THUNDERSTORMS CONTINUED ACROSS SOUTH CENTRAL MISSOURI EARLY SATURDAY MORNING. THE STORMS WERE FORMING NORTH AND EAST OF A BOUNDARY THAT EXTENDED FROM KANSAS CITY TO NEAR SPRINGFIELD. LOW LEVEL WINDS FROM THE SOUTHWEST WILL CONTINUE TO INTERSECT THIS BOUNDARY...AND FEED VERY MOIST AND UNSTABLE AIR INTO THE STORM COMPLEX. THE STORMS WILL GENERALLY MOVE SOUTH AND SOUTHEAST AND AFFECT SOUTH CENTRAL MISSOURI. SOME OF THESE STORMS WILL PRODUCE LARGE HAIL AND STRONG WINDS. TORRENTIAL RAINFALL RATES IN EXCESS OF A TWO INCHES PER HOUR WILL ACCOMPANY SOME OF THESE STORMS WITH RAINFALL TOTALS IN EXCESS OF THREE INCHES LIKELY. THESE RAINFALL AMOUNTS COULD RESULT IN FLASH FLOODING. A LAYER OF WARM AIR AT THE MID-LEVELS OF THE ATMOSPHERE WILL INHIBIT STORMS FROM DEVELOPING OVER FAR WESTERN MISSOURI AND EXTREME SOUTHEAST KANSAS. THE GREATEST THREAT FOR SEVERE THUNDERSTORMS THROUGH THE EARLY MORNING HOURS WILL BE EAST OF THE SPRINGFIELD AREA. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
