NWS Quad Cities, IA wrote its last area forecast discussion before the first event at Aug 19, 2:08 PM CST, 5 hours 7 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 308 PM CDT SUN AUG 19 2007 .SYNOPSIS... SURFACE BOUNDARY HAS LIFTED NORTH TO AXIS ROUGHLY FROM INDEPENDENCE TO PRINCETON WITH WIDESPREAD SHOWERS AND THUNDERSTORMS TO THE SOUTH IN DEEP TROPICAL MOISTURE PROFILE. REMNANTS FROM T.D. ERIN WERE ANALYZED AT 12Z OVER N CENTRAL OK BUT HAS SINCE SHOWED SIGNS ON SATELLITE WV IMAGERY SHEARING OUT TO THE EAST. WIDESPREAD ISENTROPIC LIFT/WARM MOIST ADVECTION EXTENDED NORTHEAST OF THE DECAYING CYCLONE INTO MO...IL...AND IA...FEEDING THE ON-GOING CONVECTION WITH VERY HEAVY RAINFALL RATES. ANOTHER FEATURE OF NOTE WAS UPPER SHORTWAVE MOVING EAST ACROSS SD THAT WILL IMPACT LOCAL AREA TONIGHT. && .SHORT TERM...TONIGHT AND MONDAY... CHALLENGING FORECAST WITH POTENTIAL FOR ADDITIONAL HEAVY RAINFALL IN REGION AND WILL CONTINUE WITH ON-GOING FLASH FLOOD WATCH. WILL EXPAND THIS WATCH FURTHER SOUTH TO COVER ENTIRE CWA DUE TO UNCERTAINTY IN AREAS OF HIGHEST QPF TONIGHT...COMBINED WITH HEAVY RAINFALL TODAY THAT HAS SATURATED PORTIONS OF AREA ALONG AND SOUTH OF I-80. ADDITIONAL VORT LIFTING NORTHEAST AHEAD OF MAIN DECAYING LOW WILL FEED ADDITIONAL STORMS TONIGHT...BEFORE REMNANTS LIFT NORTHEAST SUGGESTING NORTHEAST PORTION OF CWA TO HAVE BEST POTENTIAL FOR HEAVY RAINFALL. LOW CONFIDENCE IN MODEL HANDLING OF THIS FEATURE...WHICH 18Z ANALYSIS INDICATED HAD LOST MOST OF ITS LOW LEVEL CIRCULATION....BUT ALL NGM/NAM/GFS LIFT NORTHEAST INTO EASTERN CWA TOWARD MORNING. ANOTHER SOURCE OF LIFT IS SHORTWAVE MOVING THROUGH DAKOTAS THAT IS ALREADY FEEDING CONVECTION IN SOUTHERN MN...WHICH WILL LIKELY EXPAND E-SE WITH ACTIVATION OF NOCTURNAL LOW LEVEL JET AND RICH MOISTURE FEED. UPSHOT IS POTENTIAL FOR LARGE AREA OF 1 TO 2 INCH RAINFALL AMOUNTS OVER NEXT 12-18 HOURS WITH LOCAL AMOUNTS MUCH HIGHER IN NW IL WERE PARAMETERS FAVORABLE FOR TRAINING STORMS WILL BE MAXIMIZED. ON MONDAY...SURFACE BOUNDARY PROGGED TO LINGER ACROSS CWA...WHICH COMBINED WITH ADDITIONAL WEAK SHORTWAVES IN MID LEVEL WESTERLIES OVER AREA WILL CONTINUE CHANCES FOR THUNDERSTORMS. BREAK IN FLOW OF RICH GULF MOISTURE SHOULD DIMINISH POTENTIAL FOR ADDITIONAL HEAVY RAINFALL. ..SHEETS.. .LONG TERM...MONDAY NIGHT SUNDAY... MESSY FORECAST THROUGH THE LONG TERM. FAIRLY STAGNANT PATTERN PERSISTS WITH OVERALL ZONAL FLOW ACROSS THE UPPER MIDWEST AND STATIONARY OR WARM FRONTS HOVERING OVER THE AREA THROUGH MID WEEK. MAIN FORECAST CHALLENGE IS TO NARROW TIMING OF GREATEST PRECIP CHANCES. AT THIS POINT IT LOOKS LIKE THE BEST CHANCE FOR A BREAK IS WEDNESDAY AS THE SURFACE FRONT HANGS TO OUR WEST AND THE MODELS SUGGEST WE WILL BE BETWEEN SHORT WAVES. MAIN MODE OF CONVECTION IS EXPECTED TO BE NOCTURNAL. TEMPERATURES WILL BE VERY TRICKY AS THEY WILL BE HIGHLY DEPENDENT ON OVERNIGHT CONVECTION...FRONTAL POSITION...AND CLOUD COVER. A MORE SIGNIFICANT CHANGE COMES FRIDAY/SATURDAY AFTER THE MODELS PUSH A COLD FRONT THROUGH...DRYING THINGS OUT FOR THE WEEKEND. GIVEN ALL OF THE UNCERTAINTY...HAVE MADE ONLY MINOR TWEAKS TODAY. WE JUST HAVE TO TAKE THIS WEEK ONE EVENT AT A TIME. && .AVIATION... STATIONARY FRONT WILL LINGER ACROSS EASTERN IA INTO NORTHERN IL THROUGH MONDAY...WHICH COMBINED WITH A FEED OF TROPICAL MOISTURE FROM REMNANTS OF ERIN WILL CONTINUE WIDESPREAD THUNDERSTORMS TONIGHT INTO MONDAY. THUNDERSTORMS TONIGHT WILL HAVE EXCESSIVE RAINFALL RATES AND IFR CIGS/VISBYS AND MOST COMMON ALONG AND NORTH OF CID TO MLI TERMINALS. SOUTH...INCLUDING BRL...WILL BE MORE SCATTERED. LINGERING LOW LEVEL MOISTURE WILL LIKELY LEAD TO IFR CIGS AND FOG MON MORNING TO IMPACT MOST TERMINALS. CONDITIONS SHOULD LIFT TO MVFR BY MON AFTERNOON. 33 && .DVN WATCHES/WARNINGS/ADVISORIES... IA...FLASH FLOOD WATCH THROUGH MONDAY AFTERNOON. IL...FLASH FLOOD WATCH THROUGH MONDAY AFTERNOON. MO...FLASH FLOOD WATCH THROUGH MONDAY AFTERNOON. && SHEETS/33

PERIODS OF THUNDERSTORMS WITH TORRENTIAL RAIN WILL CONTINUE TONIGHT...CAUSING LOCALIZED FLASH FLOODING. RAINFALL RATES OF 2 TO 3 INCHES PER HOUR ARE EXPECTED TO CAUSE FLASH FLOODING... PARTICULARLY IN URBAN OR HILLY AREAS. THERE IS A SLIGHT CHANCE THAT SOME OF THE STORMS THIS AFTERNOON INTO THIS EVENING AND EVENING COULD BECOME SEVERE...MAINLY ALONG AND NORTH OF HIGHWAY 20 AND WEST OF THE MISSISSIPPI RIVER. THE MAIN SEVERE THUNDERSTORM THREAT WOULD BE DAMAGING WINDS. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY REPEATED BOUTS OF HEAVY RAIN WILL CONTINUE MONDAY...AND POSSIBLY INTO TUESDAY. EACH ROUND OF THUNDERSTORMS WILL HAVE THE POTENTIAL TO PRODUCE HEAVY RAIN AND LOCALIZED FLASH FLOODING. IF MULTIPLE ROUNDS OF THUNDERSTORMS MOVE OVER THE SAME AREA...RIVER LEVELS WILL ALSO BEGIN TO RISE RAPIDLY. THERE IS MUCH FORECAST UNCERTAINTY IN BOTH THE LOCATION OF THE HEAVIEST RAIN AND THE EXACT AMOUNT OF RAINFALL AT ANY SPECIFIC LOCATION. YOU SHOULD MONITOR WEATHER AND RIVER FORECASTS CLOSELY OVER THE NEXT FEW DAYS AND BE PREPARED TO TAKE QUICK ACTION IF FLOODING IS OBSERVED OR A WARNING IS ISSUED. WEDNESDAY THROUGH FRIDAY...THE FRONT WILL CONTINUE TO LINGER NEAR THE AREA. THIS WILL RESULT IN ADDITIONAL ROUNDS OF SHOWERS AND THUNDERSTORMS WITH THE RISK OF ADDITIONAL HEAVY RAINFALL AND LOCALIZED FLOODING FROM RAIN SOAKED SURFACES. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NEEDED OVER PORTIONS OF NORTHEAST IOWA THIS AFTERNOON AND EVENING. AREA WIDE...PLEASE REPORT RAINFALL AMOUNTS OVER ONE INCH AND ANY FLOODING TO THE NATIONAL WEATHER SERVICE FORECAST OFFICE IN THE QUAD CITIES. 33
