AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 331 AM CDT TUE JUL 4 2006 .DISCUSSION... EARLY MORNING SATELLITE IMAGERY SHOWS A COMPLEX PATTERN DOMINATING THE CENTRAL PLAINS THIS MORNING. A SMALL CUTOFF LOW CONTINUES TO SPIN AROUND OVER CENTRAL TEXAS...EMBEDDED WELL WITHIN THE EAST EDGE OF A AMPLIFIED WEST CONUS RIDGE. A CURSORY INSPECTION OF THE WATER VAPOR IMAGERY CONTINUES TO SHOW ABUNDANT MOISTURE WRAPPING NORTH THROUGH THE DESERT SOUTHWEST INTO THE CENTRAL PLAINS. MEANWHILE THE CUTOFF LOW HAS LENT ITS ASSISTANCE TO RETURNING GULF MOISTURE. A MORE DETAILED INSPECTION ILLUMINATES THE PRESENCE OF A SHORTWAVE MOVING EAST THROUGH IOWA AND NORTHERN MISSOURI. AT THE SURFACE TWO BOUNDARIES CAN BE FOUND ACROSS THE PLAINS. THE FIRST IS A WEAKLY DEFINED BOUNDARY STRETCHING FROM MHK EAST NORTHEAST TO THE NORTH OF MCI TO JUST SOUTH OF IRK. THE SECOND FRONT IS BETTER DEFINED BY THE DEWPOINT DISCONTINUITY ACROSS IT AND IS FOUND FARTHER NORTH. THIS FRONT MARKS THE BOUNDARY BETWEEN THE HOT MOIST AIRMASS CURRENTLY OVER THE CENTRAL PLAINS AND THE COOL DRY CANADIAN AIRMASS SHIFTING SOUTH IN THE NORTHWEST FLOW OF THE NORTHERN PLAINS. THE WEAKER BOUNDARY IN MISSOURI APPEARS TO BE THE FOCUS FOR OVERNIGHT CONVECTION. NOT BECAUSE ANY OF IT IS SURFACED BASED...BUT BECAUSE IT IS COINCIDENT WITH THE NORTHERN EDGE OF THE HIGHER THETA-E AIRMASS ALOFT AT 850MB AND ABOVE. YESTERDAYS AND THIS MORNINGS ACTIVITY HAS RANGED AROUND AND NORTH OF THE MISSOURI RIVER THUS FAR. HOWEVER...WITH THE LOW LEVEL JET GETTING INTO THE ACT IN EASTERN KANSAS THE ACTIVITY IS BEGINNING TO WORK ITS WAY FARTHER SOUTH IN EASTERN KANSAS. THESE STORMS WILL MOVE EAST THIS MORNING AS THE JET VEERS INTO A WEST TO EAST ORIENTATION AS THE SHORTWAVE MOVES EAST. THIS IS EXPECTED TO BRING RAIN TO THE MUCH OF THE SOUTHERN REACHES OF THE FORECAST AREA BY SUNRISE. THE WEIGHT OF THE COLD AIR GENERATED BY THE RAINFALL OVERNIGHT..AND THE HIGH PRESSING SOUTH...WILL FORCE CONVECTION SOUTH. MODEL CONSENSUS BETWEEN THE GFS AND WRF BACKS THIS IDEA UP AS THEY SHOW ACTIVITY ALONG AND SOUTH OF THE MISSOURI RIVER THROUGH NOON. KEPT LIKELY POPS ALONG THE SOUTHEASTERN EDGE OF THE FORECAST AREA...TAPERING TO CHANCE POPS FROM KANSAS CITY THROUGH KIRKSVILLE. AFTERNOON HOURS WILL SEE MOST ACTIVITY SHIFT INTO CENTRAL AND SOUTHERN MISSOURI. WITH MODEL SOUNDINGS INDICATING A LACK OF ANY CAP...STORMS ARE EXPECTED...BUT WITH NO STRONG FEATURE SUCH AS AN UPPER LEVEL WAVE OR FRONTAL CONVERGENCE TO FOCUS ACTIVITY COVERAGE SHOULD BE LIMITED ENOUGH TO ONLY WARRANT CHANCE POPS. OTHERWISE...ONLY MINOR MODIFICATIONS WHERE MADE TO OUR TEMPERATURES OVER THE NEXT FEW DAYS. && .PREVIOUS DISCUSSION... 140 PM... SIGNIFICANT CHANGES TO OCCUR THE NEXT COUPLE OF DAYS AS THE THREAT OF CONVECTION WILL DRAMATICALLY INCREASE TONIGHT AND TUESDAY... ALONG WITH A PUSH OF COOLER AND DRIER AIR. THE FORECAST STILL REMAINS RATHER TRICKY AS THE CONVECTIVE TIMING AND HOW QUICKLY THE COOLER AIR WORKS SOUTH IS STILL A LITTLE UNCERTAIN. OVERALL...PREFER THE NAM MASS FIELDS THE NEXT COUPLE OF DAYS. ALSO PREFER THE LESS NOISY PRECIPITATION PATTERN OF THE WRF. HOWEVER...THE GFS DOES APPEAR TO HAVE ITS LOCATION OF THE PRECIP SHIELD CORRECT FOR TONIGHT AND EARLY TUESDAY. FIRST CONCERN IS A WEAK SHORTWAVE TROUGH MOVING SLOWLY EAST ALONG THE KS AND NEB BDR NORTH OF RSL. STRONGEST ELEVATION CONVECTION APPEARS TO BE TIED TO THE H8-H7 THETAE RIDGE NOTED IN THE VICINITY OF AN OLD DECAYING BOUNDARY FM GRI TO NR OMA. REINFORCING SHOT OF COOLER AIR APPEARS TO BE READY TO DESCEND INTO NRN NEB AND NRN IA LATE THIS AFTN WITH THIS COOLER AIR MASS NOT TO REACH THE I-70 CORRIDOR UNTIL LATE TUESDAY AFTN. THE SHORTWAVE TO OUR WEST WILL HELP TO DEVELOP A LARGE AREA OF SHOWERS AND THUNDERSTORMS TONIGHT THROUGHOUT XTRM NE KS AND NRN MO. SEVERE WX DOES NOT APPEAR TO BE A THREAT DUE TO WEAK SFC-6KM SHR...POOR LAPSE RATES AND MUCAPES FM 1000-2000 J/KG. THE CONVECTIVE COMPLEX WILL SAG SOUTH TO THE I-70 CORRIDOR SHORTLY AFTER MIDNIGHT AS THE WEAK LLJ VEERS AND THE H8-H7 THETA-E RIDGE BECOMES ORIENTED FROM WEST CENTRAL TO CENTRAL MO. THE AIR MASS IS EXPECTED TO BE QUITE MOIST THROUGH THE MORNING HOURS WITH PRECIPITABLE WATER VALUES AROUND 2 INCHES. PRIOR TO THE DEVELOPMENT TONIGHT...A WEAK OUTFLOW BOUNDARY HAS DEVELOPED FROM THIS MORNINGS CONVECTION IN NW MO. THE BOUNDARY IS LOCATED FROM MCI TO IRK. THIS BOUNDARY IN CONJUNCTION WITH DIFFERENTIAL HEATING THAT IS NOTED ON THE SE EDGE OF AC FIELD...WILL LIKELY GENERATE SCT CONVECTION. THE CONVECTION MAY BECOME MARGINALLY SEVERE WITH DAMAGING WINDS POSSIBLE DUE TO COLLAPSING DOWNDRAFTS. OTHERWISE...CORFIDI VECTORS SHOW A VERY SLOW PROPAGATION TO SOUTH OF THE TROPICAL LIKE MCS OVERNIGHT WITH A WEAK HINT OF TRAINING POSSIBLE. HOWEVER...ANY TRAINING OF ECHOES SHOULD BE KEPT TO MINIMUM AS THE STRONGEST CONVECTION WILL MOVE SLOWLY SOUTH WITH THE THETAE RIDGE. REGARDLESS...HEAVY RAINFALL AMOUNTS ARE POSSIBLE...BUT WITH VERY DRY CONDITIONS...NO HEADLINES ARE NEEDED. THE PRECIPITATION WILL LIKELY LINGER ACROSS THE SRN CWA TUESDAY MORNING. ALTHOUGH THE CONVERGENCE ALONG THE COLD FRONT TUESDAY AFTN IS EXPECTED TO BE WEAK...CONVECTION MAY REDEVELOP ALONG THE BOUNDARY NEAR INTERSTATE 70 AS THE SOUNDINGS ARE INDICATING LITTLE IF ANY CAP. WILL KEEP CHCS LOW DURING THE AFTN. THE COOLER AND DRIER AIR WILL WEDGE ITS WAY INTO MO TUESDAY NIGHT WITH A COOLER AND DRIER DAY ON WEDNESDAY. DB VERY LITTLE IN THE WAY OF SENSIBLE WEATHER IN THE MEDIUM RANGE WITH COOL MODIFIED CANADIAN HIGH PRESSURE GIVING WAY TO BUILDING MIDLEVEL HEIGHTS AND RETURN FLOW BY THE END OF THE WEEK. MODEL DIFFERENCES INTO THE WEEKEND BEGIN TO ARISE CONCERNING THE STRENGTH OF THE RIDGE AXIS...AND THE POSSIBILITY OF SHORTWAVE ENERGY FROM AN ACTIVE EAST PACIFIC JET BREAKING THROUGH THE TOP OF THE RIDGE AND INITIATING CONVECTION IN NWLY FLOW. SIGNIFICANT SPREADS IN ENSEMBLE SOLUTIONS AND POOR RUN TO RUN CONSISTENCY AMONG ALL OPERATIONAL MODELS PRECLUDES THE MENTION OF PRECIPITATION JUST YET IN THE MEDIUM RANGE. LATER SHIFTS WILL NEED TO MONITOR MODEL TRENDS REGARDING RIDGE STRENGTH AND POSITIONING...AND THE IDENTIFICATION OF ANY PARTICULARLY ACTIVE SHORTWAVE WHICH COULD TEMPORARILY BREAK DOWN THE RIDGE. 21 && .EAX WATCHES/WARNINGS/ADVISORIES...
