AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 314 AM CDT FRI JUN 19 2009 .SYNOPSIS...TWO STORM CLUSTERS ARE CURRENTLY MOVING THROUGH THE REGION. FIRST OVER SOUTHERN WI AND NORTHERN IL DEVELOPED IN LOW- LEVEL WAA AND HAD LITTLE EFFECT ON OUR AREA. SECOND AND MORE OF CONCERN TO US IN THE CLUSTER OF STORMS IN SOUTHEAST NE AND EXTREME WESTERN IA...ALONG THE FRONTAL BOUNDARY WHICH STRETCHES FROM SOUTHWEST KS NORTHEAST INTO SOUTHERN MN. && .SHORT TERM...TODAY AND TONIGHT. MAIN CONCERN FOR US IS THREAT OF SEVERE WEATHER TODAY AND THIS EVENING. CLUSTER OF STORMS TO OUR WEST WILL BE THE KEY TO OUR THREAT TODAY. IF THEY HOLD TOGETHER AND DEVELOP INTO A WELL ORGANIZED SYSTEM AND TAP INTO THE HIGHLY UNSTABLE AIR OVER IOWA...THAT WILL BE THE PROBLEM OF THE DAY. IF THE CAP HOLDS AND THE STORMS WEAKEN AS THEY MOVE EAST...THEN THE CHALLENGE WILL BE TO ASSESS THEIR IMPACT ON THE ENVIRONMENT OVER THE STATE AND THE POTENTIAL FOR REDEVELOPMENT LATER THIS AFTERNOON AND EVENING AS THE SURFACE COLD FRONT MOVES THROUGH THE CWA. INSTABILITY IS QUITE HIGH WITH SBCAPES BETWEEN 2000 AND 3000 J/KG...EVEN AT THIS TIME IN THE MORNING. HOWEVER...CIN IS HIGH ESPECIALLY OVER THE SOUTHERN PART OF THE CWA. 0-6KM SHEAR SUPPORTS WELL ORGANIZED CONVECTION...PERHAPS EVEN SUPERCELLS IF UPDRAFTS ARE SURFACE-BASED...BUT 0-1KM SHEAR AND SSW SURFACE WINDS ARE NOT PARTICULARLY FAVORABLE FOR TORNADOES. MAIN THREATS TODAY WILL BE WIND AND LOCAL HEAVY RAIN/FLASH FLOODING. RECENT RAINS HAVE SATURATED SOILS IN MANY PARTS OF THE CWA...BUT WILL HOLD OFF ON ISSUING A FLASH FLOOD WATCH AS THE DETAILS OF THE THREAT REMAIN UNCLEAR. MODELS AGREE IN BRINGING THE FRONT THROUGH THE CWA THIS EVENING WHICH SHOULD END THE SEVERE/HEAVY RAIN THREAT. .LONG TERM...SATURDAY THROUGH THURSDAY THE UPPER TROUGH SHIFTS TO OUR EAST BY SATURDAY BUT THE WARM MOIST AIR MASS AND JET AXIS WILL PERSIST OVER THE MID AND UPPER MISSISSIPPI RIVER VALLEY INTO NEXT WEEK. THUS WHILE THIS WOULD SUPPORT AT LEAST SOME CHANCE OF RAIN...SURFACE FEATURES IN ALL THE MODELS ARE VERY WEAK AND ILL-DEFINED...THUS IT IS HARD TO PIN DOWN POP CHANCES. WAA RETURNS SUNDAY AS THE WARM FRONT LIFTS BACK NORTH... SO HAVE SOME POPS ASSOCIATED WITH THIS. TEMPS AND HUMIDITY THE NEXT WEEK WILL BE RATHER SUMMER-LIKE. && .AVIATION...EXPECT VFR CONDITIONS THROUGH THE FORECAST PERIOD OUTSIDE OF THUNDERSTORMS...WHERE VERY MOIST CONDITIONS WILL RESULT ON IFR-LIFR CIGS AND VSBYS WHERE THE STORMS OCCUR. && .DVN WATCHES/WARNINGS/ADVISORIES... IA...NONE. IL...NONE. MO...NONE. && WOLF

THE ATMOSPHERE IS VERY UNSTABLE AND WINDS ALOFT SUPPORT WELL ORGANIZED THUNDERSTORMS CAPABLE OF PRODUCING DAMAGING STRAIGHT-LINE WINDS. INTENSE RAINFALL WILL OCCUR WITH THESE STORMS THAT MAY CAUSE MINOR FLOODING. WHERE MULTIPLE THUNDERSTORMS TRACK OVER THE SAME AREA...FLASH FLOODING IS LIKELY. THE FIRST GROUP OF THUNDERSTORMS IS CURRENTLY IN WESTERN IOWA AND MOVING EASTWARD. THIS COULD BRING A ROUND OF MORNING SEVERE WEATHER. AS THE COLD FRONT MOVES THROUGH THE AREA LATER THIS AFTERNOON AND EVENING...ANOTHER ROUND OF SEVERE THUNDERSTORMS IS POSSIBLE. THE THREAT OF SEVERE WEATHER WILL END LATER TONIGHT WHEN THE COLD FRONT EXITS THE AREA. THE STORM PREDICTION CENTER HAS ALMOST ALL OF THE AREA UNDER A MODERATE RISK OF SEVERE THUNDERSTORMS...THUS AN EMERGENCY MANAGEMENT CONFERENCE CALL WILL BE SCHEDULED LATER TODAY TO DISCUSS THE SEVERE THREAT. IN ADDITION...SOME AREA RIVERS ARE EXPERIENCING GENERALLY MINOR FLOODING. PLEASE SEE THE LATEST FLOOD STATEMENTS AND FLOOD WARNINGS FOR DETAILS. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY THE PROBABILITY OF WIDESPREAD HAZARDOUS WEATHER IS LOW. .SPOTTER INFORMATION STATEMENT...
