Area forecast discussion, Jul 23, 3:15 PM CDT, 2 hours 28 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DES MOINES IA 315 PM CDT SAT JUL 23 2011 .SHORT TERM /TONIGHT/... A COMPLICATED WX PATTERN WITH NUMEROUS OUTFLOW BOUNDARIES AND THE MONSOONAL FLOW WELL POSITIONED OVER IA. CONVECTION DURG THE DAY KEPT A BROAD SWATH OF CNTRL IA COOL TODAY AND THAT COOL AIR WAS DRAWN NWD INTO THE NERN CONTIES. ONLY THE SRN 3 TIER WARMED INTO THE 90S THIS AFTN AND FOR THAT REASON WILL DROP HEADLINES XCP FOR THE HEAT WARNING OVR THE SRN 3 TIER. CDFNT WILL MOVE INTO NWRN IA LATER THIS EVE AND EXPECT TO SEE A LINE OF TSRA FORM WITH THAT. PUT GUSTY WINDS IN THE NWRN HALF OF THE CWA THRU THE EVE. BEST SUPPORT IS TO THE NORTHEAST OF THE CWA. AS TSRA MOVE INTO THE MOISTURE PLUME WOULD FEEL THE TSRA WILL BECOME MORE MULTI-CELLULAR IN NATURE AND REDUCE THE SVR THREAT. WOULD NOT BE SURPRISED TO SEE SOME 2+ INCH AMOUNTS IN SPOTS...BUT WITH FFG QUITE HIGH MOST OF THE CWA WITH THE EXCEPTION OF A FEW COUNTIES OVR THE NORTHEAST...AM NOT TOO CONCERNED ABOUT THAT. .LONG TERM /SUNDAY THROUGH MONDAY NIGHT/... STRONG SHORTWAVE TROUGH MOVING EAST ACROSS SOUTHERN CANADA SUNDAY MORNING IS FORECAST TO SOUTHEAST INTO THE GREAT LAKES BY 00Z TUESDAY. THE MODELS ARE IN PRETTY GOOD AGREEMENT THE THIS FEATURE. AS A RESULT...UPPER FLOW BECOMES NORTHWESTERLY SHOULD SHOULD RESULT COLD FRONT CLEARING THE STATE ON SUNDAY. 12Z FRONTAL POSITION SHOULD BE THROUGH CENTRAL IOWA. THE PLACEMENT OF THE FRONT WILL BE PROBLEMATIC BECAUSE OF TONIGHT/S CONVECTION. NONE THE LESS...EXPECT FRONT TO EXIT SOUTHERN IOWA SUNDAY AFTERNOON. ALOFT...MID/HIGH LEVEL MOISTURE FETCH MOVING AROUND SUBTROPICAL HIGH SHOULD BE PUSHED INTO MISSOURI AND FAR SOUTHERN IOWA BY SUNDAY AFTERNOON. IT/S BEEN UNSETTLED IN THE VICINITY OF THE TROPICAL MOISTURE BAND AND EXPECT CLOUDS AND A CHANCE OF SHOWERS AND THUNDERSTORMS SOUTHERN COUNTIES SUNDAY AFTERNOON. OF COURSE...HAVING THE FRONT MOVING THROUGH TO MAXIMIZE LOW-LEVEL CONVERGENCE DOESN/T HURT. SURFACE HIGH SHOULD PROVIDE 36 HOURS OF LOW POPS...COOLER TEMPS AND LOWER DEW POINTS WHICH WILL BE A NICE CHANGE GIVEN THE RECENT PATTERN. .EXTENDED/TUESDAY THROUGH SATURDAY/... MCS IS EXPECTED TO BE ONGOING ACROSS THE MISSOURI RIVER VALLEY AT THE START OF THE PERIOD TUESDAY MORNING. IT SHOULD DISSIPATE THROUGHOUT THE DAY IN RESPONSE TO THE LACK OF FORCING ASSOCIATED WITH THE WEAKENING LOW LEVEL JET. MEANWHILE...ANOTHER WAVE FURTHER WEST WILL BE CROSSING THE NORTHERN ROCKIES ON TUESDAY. MODELS DIFFER ON THE TIMING AND PLACEMENT...WITH THE ECMWF LESS AMPLIFIED AND THEREFORE MORE PROGRESSIVE...WHILE THE GEM...AND MORE SO GFS BEING STRONGER AND A BIT SLOWER. THE DIFFERENCE MANIFESTS ITSELF IN THE LOCATION OF THE LEE SIDE SURFACE LOW ACROSS THE HIGH PLAINS. USED A MODEL BLEND TO ACCOUNT FOR THE UNCERTAINTY...WITH BEST POPS ACROSS THE NORTH TUESDAY THROUGH WEDNESDAY. WARM MOIST BOUNDARY LAYER WILL YIELD HIGH CAPE VALUES ON WEDNESDAY...BUT H850 TEMPS OF 25+C SHOULD CAP OFF CONVECTION OVER THE MAJORITY OF THE CWA EXCEPT FOR NORTHERN TIER. SURFACE LOW THEN MOVES EASTWARD...AND TRAILING COLD FRONT BECOMES EAST/WEST ORIENTED AND STALLS OUT ACROSS THE CWA AMIDST ZONAL FLOW...BEFORE SLOWLY PUSHING SOUTH BY THE WEEKEND. MORE WIDESPREAD CONVECTION IS EXPECTED THURSDAY AFTERNOON/NIGHT WITH THE ARRIVAL OF THE AFOREMENTIONED SHORTWAVE. THEREFORE HAVE KEPT LOW POPS THROUGH FRIDAY...AND TARGETED HIGHEST CHANCE WITH THE SHORTWAVE/LLJ THURSDAY NIGHT. A FEW STRONG TO SEVERE STORMS ARE POSSIBLE DURING THIS STRETCH. DEEP LAYER SHEAR IS A MARGINAL 25-35KTS...SO CANT RULE OUT SOME LOCALIZED DAMAGING WINDS. DAILY TEMPS WILL BE GREATLY INFLUENCED BY CONVECTION...SO DIDNT STRAY TOO MUCH FROM GUIDANCE. && .AVIATION...23/18Z FCST IS COMPLICATED BY MULTIPLE OUTFLOW BOUNDARIES FROM OVERNIGHT CONVECTION. MAIN BAND IS ASSOCIATED WITH LIFTING WRMFNT EXTENDING EAST TO WAST ACRS THE STATE. WILL GO WITH CB REMARK IN TAF SITES AND EXPECT THE MAIN AREA TO BE NORTH OF KDSM AND OTM...AND SOUTH OF REMAINDER. CDFNT WILL MOVE INTO NWRN IA TNGT WITH A MORE ORGANIZED AREA OF TSRA. TRIED TO TIME THE BEST CHC FOR TSRA IN A TEMPO PD...WITH A BROAD AREA OF VCTS AS SYSTEM WILL BE QUITE DIFFUSE MOVING AS IT MOVES THRU. WOULD EXPECT TO SEE SOME MVFR CIGS MOVE INTO THE KMCW AREA SUN MORNING POST FROPA. THINKING IS THEY WILL BREAKUP BEFORE GETTING MUCH FARTHER SOUTH. && .DMX WATCHES/WARNINGS/ADVISORIES...
