NWS Quad Cities, IA wrote its last area forecast discussion before the first event at Jun 7, 2:02 PM CST, 7 hours 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 302 PM CDT SUN JUN 7 2009 .SYNOPSIS... THE 2 PM SURFACE ANALYSIS INDICATES UPPER MIDWEST RAPIDLY CLEARING RAPIDLY OVER FORECAST AREA ALLOWING FOR FAVORABLE CONDITIONS FOR CONVECTION LATE THIS AFTERNOON. NOWCAST TOOLS SUGGEST INITIATION ALONG AND ESPECIALLY WEST OF I-35 CIRCA 4-5 PM. PROPAGATION VECTORS AND VARIOUS LOCAL TECHNIQUES SUPPORT STRONG CONVECTION TO PROPAGATE AND MOVE EAST NORTHEAST INTO FORECAST AREA THIS EVENING WITH BACK- BUILDING POTENTIAL INTO MONDAY AM. PW/S AOA 1.5 INCHES SUPPORT HEAVY TO LOCALLY HEAVY RAINS. UPPER AIR ANALYSIS SUPPORTS SFC LOW TO PASS OVER FORECAST AREA EARLY TOMORROW WITH QUESTION OF REDEVELOPMENT BEFORE SYSTEM MOVES EAST BY MID/LATE MONDAY AFTERNOON. && .NEAR TERM...TONIGHT... INITIATION AND MODEL VERIFICATION SUPPORT USAGE OF UKMET/HI RES ECMWF FORCING...SUPPLEMENTED BY UPPER LEVEL FORCING OF 80 KM NAM-WRF. FAIRLY STRAIGHTFORWARD FORECAST TONIGHT...LOCAL TOOLS AND TECHNIQUES SUPPORT MCS WITH SOME BOWING SEGMENTS TO DEVELOP IN WESTERN HALF OF IOWA AND MOVE INTO FORECAST AREA BY MID-EVENING WITH STRONG TRAINING OF STORMS POTENTIAL ALONG AND NORTH OF HIGHWAY 30 ALONG 925-850 UPPER LEVEL FRONT PER WARM ADVECTION WIND TOOL. SOME MODEST INSTABILITY MAY ALLOW PER LOCAL TECHNIQUES AND ALGORITHMS FOR ISOLATED SEVERE INTO LATE EVENING...MAINLY FOR STRAIGHT LINE WINDS UP TO NEAR 60 MPH...MOST GUSTS WITH STORMS SHOULD FALL IN THE 35 TO 45 MPH RANGE. LOW LEVEL JET OF 40 KTS LATER TONIGHT MAY ALLOW FOR ELEVATED CONVECTION WITH SOME DRY INTRUSION FROM SW MAY SUPPORT ISOLATED LARGE HAIL UP TO HALF DOLLAR SIZED...OR 1.25 INCH IN DIAMETER. HEAVY RAIN MAIN RISK TONIGHT WITH LOCALIZED 1 TO 2 INCHES NORTH OF I-80 AND LOCALIZED 3 PLUS POSSIBLE WITH TRAINING AND INTERSECTING BOUNDARIES ALONG TRIPLE POINT. SOME MINOR FLOODING POSSIBLE BUT AREA RIVERS AND FLASH FLOOD GUIDANCE SUGGEST RISK NOT HIGH ENOUGH FOR A WATCH ATTM... PASS FOR EVENING SHIFT TO REASSESS. MINS TONIGHT...HAVE KEPT MAINLY IN MID TO UPPER 60S FOR WARMEST AND MUGGIEST MINS OF THIS WARM SEASON. ..NICHOLS.. .LONG TERM...MONDAY THROUGH NEXT SUNDAY... MONDAY THROUGH TUESDAY NIGHT...AS ALWAYS WITH NOCTURNAL CONVECTION AND MCS/S...WHAT DEBRIS AND BOUNDARIES THAT LINGER OUT OF SUN NIGHT INTO MON MORNING WILL BE A BIG PLAYER FOR MIDDAY AND MON AFTERNOON POTENTIAL. THE SHORT RANGE MODELS CONTINUE TO BE MORE PROGRESSIVE WITH EJECTING UPPER TROF/NOW SEEN LIFTING OUT OF THE NORTHEAST GRT BSN ON W/V IMAGERY/...WITH BULK OF THE LIFT/FORCING FROM THIS FEATURE SHIFTING EAST AND SOUTHEAST OF THE DVN CWA AFTER 18Z MON. BUT THE 12Z NAM AND GFS HAVE TRENDED BACK WESTWARD SOMEWHAT WITH THEIR DEEP CONVECTIVE AXIS WITH A MAXIMUM ACRS THE SOUTHEAST THIRD TO HALF OF THE DVN CWA BY 18Z. THIS WOULD SUGGEST MIDDAY OR EARLY AFTERNOON STORMS FIRING ALONG AND EAST OF THE MS RVR...AND EVOLVING AS THEY MIGRATE EASTWARD AHEAD OF THE FROPA AND BEST INSTABILITY AXIS. THIS PROCESS OF COURSE HIGHLY DEPENDANT ON THE CONVECTION AND DEBRIS LINGERING OUT OF SUNDAY NIGHT...AND EXPECT AN MCS ONGOING ACRS THE NORTH HALF AND THEN PROPAGATING EASTWARD OR DECAYING DIURNALLY THROUGH LATE MORNING AND WILL CONTINUE LIKELY POPS IN THE MORNING FOR THIS POTENTIAL. SOME BACK BUILDING HEAVY RAINERS MAY STILL BE ONGOING AT DAYBREAK ALONG AND NORTH OF I80...WITH LLVL SHEAR VALUES AND SRH/S STILL SUPPORTING POSSIBLY AN EARLY MORNING SEVERE RISK AGAIN BEFORE EXITING OR DECAYING AS WELL AS WIND PROFILES BECOMING UNIFORM THROUGH THE COLUMN IN A WEST-TO-SOUTHWEST MODE BY 18Z. THE NEW 12Z ECMWF SUPPORTS EARLIER THINKING OF THE PRIME SIGNIFICANT CONVECTION TAKING OFF MON AFTERNOON OCCURRING TO THE EAST AND SOUTHEAST OF THE DVN FCST AREA FROM NEAR THE WARM FRONT IN NORTHERN LOWER MI...SOUTHWESTWARD ALONG TH BEST AFTERNOON INSTABILITY AXIS THROUGH NW INDIANA AND CENTRAL IL....AND THEN EXTENDING THROUGH AND SOUTHWEST OF THE ST LOUIS AREA. WILL KEEP LIKELY POPS GOING IN THE FAR EAST AND SOUTHEAST CWA AFTER 18Z MON ALONG THE WESTERN FRINGE/GRADIENT OF DEEP CONVECTIVE INDICE MAX...BUT THEN TREND LOWER TO THE WEST AND ESPECIALLY POST- FRONTALLY. THUS A SVR POTENTIAL ALONG WESTERN INSTABILITY GRADIENT STILL POSSIBLE MON AFTERNOON IN THE FAR EASTERN CWA. COULD HAVE SOME DECENT WEST TO NORTHWEST POST FRONTAL SFC WINDS WITH GUSTS AT LEAST 30 MPH LATE MON AFTERNOON AND EVENING...POSSIBLY HIGHER WITH ANY GRAVITY WAVE INTERACTION. MOST PRECIP OUT OF THE DVN CWA BY 00Z TUE...WITH SEASONABLY DECENT CAA REGIME SETTLING IN FOR LATER MON NIGHT INTO TUE AND ONGOING TEMPS LOOK ON TARGET. WITH CONFLUENT WESTERLIES TAKING SHAPE JUST UPSTREAM...LATEST MODEL TRENDS SUPPORT AN EARLIER ARRIVAL OF NEXT MAIN WAVE OUT OF THE GRT BSN WHICH COULD FUEL AN ELEVATED SHOWER OR EVEN AN MCS LIKE COMPLEX ACRS AT LEAST THE SOUTHERN HALF OF THE FCST AREA LAT TUE NIGHT INTO WED...WITH ANOTHER SURGE/WAVE RIPPLING ALONG THE LLVL BAROCLINICITY WED NIGHT INTO EARLY THU MORNING. EACH OF THESE WAVE PASSAGES WILL BE ACCOMPANIED BY A SOUTHWESTERLY ENHANCED LLJ AND ELEVATED THTA-E FEED AND CONVERGENCE...WITH ENOUGH MID LAYER CAPES AND INSTABILITY TO FUEL A FEW EMBEDDED THUNDERSTORMS ACRS THE SOUTHERN THIRD OF THE FCST AREA TUE NIGHT AND AGAIN LATE WED INTO WED NIGHT. BUT HOW FAR NORTH OR SOUTH THESE PROCESSES WILL OCCUR AND HOW MUCH OF THE LOCAL AREA THEY WILL EFFECT STILL SOMEWHAT UNCERTAIN AND WILL MAINTAIN SLIGHT CHC/C ACRS THE NORTH...AND MODERATE CHC POPS IN THE CENTRAL ANS SOUTHERN CWA THROUGH THIS MID WEEK PERIOD. CLOUD COVER/DEBRIS COULD MAKE WED GUIDANCE HIGHS TOO OPTIMISTICALLY MILD AND MAY UNDERCUT FURTHER FORM THE ALREADY COOL/SUB-GUIDANCE HIGHS ONGOING IN THE GRIDS. WILL WALK LINGERING OVERRUNNING SHOWERS OUT OF THE SOUTHERN CWA THU MORNING...AND ANY CLEAR OUT WILL SET THE STAGE FOR A SEASONABLY COOL THU NIGHT WITH SOME UPPER 40S POSSIBLE IN THE NORTH. MEDIUM RANGE ENSEMBLES GENERALLY SUGGEST DIGGING WEST COAST OR INTERMOUNTAIN WEST L/W TROF TO EFFECTIVELY AMPLIFY EASTERN ROCKIES/ PLAINS UPPER RIDGING BY THE WEEKEND...MAINTAINING NORTHWEST FLOW AND COOL INFLUX OUT OF CENTRAL CANADA FOR THE WEEKEND. THE EXTENDED MODELS ARE DISAGREEING ON THE EXTENT OF THIS UPPER PATTERN BREAKDOWN AND POSSIBILITY OF RIDGE RIDING OR UNDERCUTTING ENERGY PRODUCING THE NEXT CHANCE FOR PRECIP IN THE LOCAL AREA. SOME LONG RANGE SIGNALS SUGGEST MAYBE ELEVATED ACTIVITY EFFECTING THE LOCAL FCST AREA LATER SAT NIGHT AND LINGERING INTO SUNDAY...BUT BIG MODEL DIFFERENCES MAKE FOR MUCH UNCERTAINTY AND WILL ONLY GO WITH PHANTOM SLIGHT CHC POPS FOR NOW FOR SAT NIGHT THRU SUNDAY NIGHT. ..12.. && .AVIATION...

THE MAIN THREAT FROM THESE STORMS WILL BE FREQUENT LIGHTNING AND BRIEF HEAVY RAIN. ISOLATED HAIL UP TO QUARTER SIZE IS ALSO POSSIBLE. LOW PRESSURE WILL BE MOVING INTO NORTHERN IOWA TONIGHT WITH A TRAILING COLD FRONT MOVING ACROSS IOWA. NUMEROUS THUNDERSTORMS WILL DEVELOP TONIGHT WITH SEVERE THUNDERSTORMS LIKELY. THE MAIN THREAT FROM THESE STORMS WILL BE DAMAGING WINDS GREATER THAN 60 MPH AND HAIL LARGER THAN QUARTER SIZE. AN ISOLATED TORNADO IS POSSIBLE THIS EVENING MAINLY NORTH OF HIGHWAY 30 IF THUNDERSTORMS CAN FORM NEAR A STALLED BOUNDARY. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY STRONG TO SEVERE THUNDERSTORMS ARE POSSIBLE MONDAY MORNING OVER THE OUTLOOK AREA AS A COLD FRONT APPROACHES FROM THE WEST. REDEVELOPMENT OF STORMS MONDAY AFTERNOON HINGES ON THE AMOUNT OF SUNSHINE AND INSTABILITY AHEAD OF THE FRONT. AT THIS TIME THE MAIN THREAT OF SEVERE STORMS MONDAY AFTERNOON WILL BE EAST OF A FREEPORT TO MACOMB LINE. THERE WILL BE A CHANCE OF THUNDERSTORMS ABOUT WEDNESDAY BUT IT IS TOO EARLY TO DETERMINE THE RISK OF SEVERE WEATHER. .SPOTTER INFORMATION STATEMENT...
