AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
320 PM CDT FRI JUN 25 2010
.SYNOPSIS...
LATEST SFC ANALYSIS WAS INDICATING A RATHER COMPLEX WAVE AND TROF
SYSTEM UP AND DOWN THE PLAINS...WITH ONE MAIN WAVE ACRS SOUTHEAST
SD...AND ANOTHER DEVELOPING JUST WEST OF THE KS/CO BORDER. ONE MAIN
WEST-TO-EAST ORIENTED WARM FRONT WAS LOCATED ACRS CENTRAL MN...AND
ANOTHER FROM FAR NORTHEAST KS...TO THE SOUTHERN MO BOOTHEEL. THIS
SOUTHERN BOUNDARY WAS FLANKED BY A LOWER 70 SFC DPT POOL. MAIN SFC
PRESSURE FALLS AREA OF INTEREST WAS CONTINUING TO DEVELOP ACRS THE
NEB/SD/IA TRI-STATE REGION AND INTO SOUTHWEST MN ATTM.
&&
.SHORT TERM...TONIGHT AND SATURDAY...
CAPPING WARM INVERSION WAS GETTING REINFORCED ALOFT ACRS IA THIS
AFTERNOON...WHILE AREAS JUST TO THE NORTH OF IT FROM SOUTHWEST ND...
THROUGH NORTHWEST IA AND SOUTHWEST MN WERE BECOMING PRIMED FOR NEW
CONVECTIVE DEVELOPMENT. EXPECT NEW SUPERCELLULAR DEVELOPMENT TO
TAKE OFF FROM NORTHEAST NEB...INTO SOUTHWEST MN AND TOWARD THE MSP
AREA BY 21-22Z. THIS ACTIVITY TO THEN MORPH INTO A LARGER CLUSTER OF
STORMS/MCS AND PROPAGATE SOUTHEASTWARD TOWARD THE DVN CWA ERODING
THE MID LAYER CAP WHILE BECOMING A SVR WIND THREAT IN THE PROCESS.
AGREE WITH NEWLY RUN HIRES RAPID REFRESH THAT A BOWING SEGMENT IN
THIS MCS COULD BE IN THE NORTHWESTERN CWA BY 03Z/10 PM CDT WITH A
STRAIGHT LINE WIND THREAT UP TO 68 MPH ACCORDING TO PROGGED
THERMODYNAMIC PROFILES AT THAT TIME. WILL ADD SVR WIND THREAT TO THE
GRIDS THROUGH 06Z TONIGHT. THE CONVECTIVE SYSTEM TO THEN CONTINUE TO
SAG ACRS THE NORTHWESTERN HALF OF THE DVN CWA THROUGH 06Z REACHING A
SIGOURNEY IA...TO THE QCA AND TO A STERLING IL LINE BY THEN. THEY
SHOULD BE IN A WEAKENING PHASE WITH A MARGINAL SVR WIND THREAT AT
THAT TIME. THE REST OF THE DVN CWA MAY THEN GET IN ON THE ACTION
THROUGH 12Z SAT MORNING IF JUST IN A DECAYING MCS MODE. BESIDES THE
WIND THREAT...SOME LOCALLY HEAVY RAIN POSSIBLE ALONG AND NORTH OF THE
HIGHWAY 30 CORRIDOR...BUT THOSE AREAS ABLE TO TAKE AN INCH OR SO.
WILL BANK ON RAINFALL RATES DECREASING AS THE ACTIVITY SPILLS FURTHER
SOUTHWARD ACRS THE RECENTLY HARD HIT AREAS LATER TONIGHT AFTER
MIDNIGHT...AND WILL NOT ISSUE A FLASH FLOOD WATCH FOR NOW.
ON SAT...WILL HAVE TO ACCOUNT FOR SOME CONVECTIVE DEBRIS IN MOST
AREAS IN THE MORNING. BUT AS THE NEXT UPSTREAM WAVE APPROACHES FROM
THE WEST ACRS THE CENTRAL AND NORTHERN PLAINS...THE MAIN SFC
BOUNDARY IS EXPECTED TO GET SOME PUSH NORTHWARD AND BE REINVIGORATED
BY INCREASING SOUTHERLY RETURN FLOW AND RETREAT AS THE DAY
PROGRESSES. HOW FAR IT GETS IS STILL A BIG QUESTION AT THIS POINT AND
AN UNCERTAINTY. THIS FRONT AND ANY LINGERING OUTFLOW BOUNDARIES OR
DEBRIS LINES WILL BE AFTERNOON AND EVENING CONVECTIVE FOCAL POINTS AN
EXPECT THEM TO BE MORE PREVALENT NORTH OF I80 AND WILL GO WITH HIGHER
CHC POPS IN THOSE AREAS AFTER 18Z. SOME LOW TO MID LEVEL SHEAR ALONG
WITH CAPES APPROACHING 4K J/KG OR EVEN HIGHER WILL FUEL ANOTHER SVR
STORM THREAT FOR SAT AFTERNOON...ALONG WITH LOCALIZED HEAVY RAINFALL.
FURTHER TO THE SOUTH OF THAT POTENTIAL...THE SOUTHERN THIRD TO HALF
OF THE DVN CWA MAY BE BATHED IN FULL-ON WARM SECTOR MODE WITH
AMBIENT TEMPS IN THE LOWER 90S AND DPTS OVER 70. IF MORNING
CONVECTIVE DEBRIS CAN CLEAR IN TIME...EXPECT AREAS SOUTH OF I80 TO
WARM INTO HEAT ADVISORY CRITERIA WITH HEAT INDICES OF WIDESPREAD 100-
103. WILL ISSUE AN ADVISORY FOR THOSE AREAS FROM 18Z SAT TO 00Z
SUNDAY. AREAS NORTH OF I80 MAY NOT RECOVER IN TIME TO REACH TRUE HEAT
ADVISORY CRITERIA...BUT WILL BE IN LINE FOR MORE NEW CONVECTION AFTER
20Z.
..12..
.LONG TERM...SATURDAY NIGHT THROUGH NEXT FRIDAY...
SATURDAY NIGHT THROUGH SUNDAY NIGHT...WILL GO WITH BROAD BRUSH
CHANCE POPS FOR THE AREA SATURDAY NIGHT AND SUNDAY FOR POTENTIAL OF
CONVECTION DEVELOPING WITH OUTFLOW BOUNDARIES DROPPING SOUTH THROUGH
THE AREA AND WITH THE COLD FRONT MOVING THROUGH THE AREA SUNDAY
MORNING/EARLY AFTERNOON. THE AREA REMAINS UNDER A SLIGHT RISK
SATURDAY NIGHT PER SPC DAY2 OUTLOOK...AND LOOKS REASONABLE WITH
GFS/NAM MUCAPES OVERNIGHT IN EXCESS OF 1500J/KG WITH DEEP LAYER
SHEAR AROUND 25 KTS. HAVE LINGERED SOME POPS IN THE SOUTHEAST FOR
SUNDAY EVENING BEHIND THE FRONT WITH THE DRIER AIR LAGGING THE
SURFACE FRONT. DRY AIR SHOULD ARRIVE BY LATE SUNDAY NIGHT SO...KEPT
THE FORECAST DRY AFTER 06Z. HAVE ALSO BACKED OFF ON TEMPS FOR
SUNDAY TO MAINLY MID-UPPER 80S DUE POTENTIAL DEBRIS CLOUDS FROM
CONVECTION AS WELL AS AN EARLY DAY FROPA.
MODELS ARE STILL ADVERTISING A PROLONGED STRETCH OF DRY WEATHER OVER
THE REGION AS A BLOCKING PATTERN SETS UP OVER THE U.S. AN UPPER
RIDGE BUILDING OVER THE PLAINS BY MONDAY WILL BE BOUNDED BY STRONG
TROFS OVER THE EAST AND WEST COASTS. THIS PATTERN IS EXPECTED TO
REMAIN IN PLACE THROUGH THE WEEK. TEMPERATURES WILL BE THE MAIN
FOCUS THROUGH THE PERIOD WITH THE 00Z ECMWF/UKMET BUILDING THE
PLAINS RIDGE INTO THE MS VALLEY BY WEDNESDAY SUGGESTING WARMER TEMPS
FOR THE ENDING OF THE WEEK. THE GEM/GFS...THOUGH..KEEP THE RIDGE TO
THE WEST THRU THURSDAY AND DIG A DEEP H5 LOW INTO THE GREAT LAKES.
THIS PLACES THE REGION IN STRONG NW FLOW AND DROPS H8 TEMPS INTO THE
SINGLE DIGITS FOR MID WEEK. FOR THIS FORECAST HAVE LEANED TOWARD
THE COOLER GEM/GFS SOLUTIONS WHICH HAVE SOME RUN TO RUN CONTINUITY
BUT KEPT TEMPS A FEW DEGREES WARMER...ESPECIALLY WED THROUGH
FRIDAY...WHEN THE MODELS START TO MOVE THE RIDGE EAST. AS A RESULT
HAVE KEPT TEMPS AT OR BELOW NORMAL FOR THROUGH WEDNESDAY...THEN NEAR
NORMAL FOR THE REST OF THE WEEK. ..DLF..
&&
.AVIATION...
MVFR CELLULAR CU TO DECAY AFTER 00Z...WITH INCREASING HIGH LEVEL
CLOUDS STREAMING IN OFF CONVECTIVE DEVELOPMENT OFF TO THE NORTHWEST.
EXPECT A SOUTH TO SOUTHEAST SFC WIND REGIME ALL NIGHT OF 5-11 KTS.
BUT THE CID AND DBQ TERMINALS TO GET IN ON A LINE OF STORMS PUSHING
IN FROM THE NORTHWEST AFTER 03Z. THESE STORMS MAY STILL HAVE A HIGH
SFC WIND THREAT AT THAT TIME WITH GUSTS OVER 65 MPH POSSIBLE THROUGH
05Z. SEVERELY REDUCED VSBYS DO TO WIND DRIVEN RAIN FROM 03Z TO 05Z
ALSO A BIG IMPACT ALONG WITH INHERENT TURBULENT LLVLS IN TE VCNTY OF
A STORM COMPLEX. THE MLI TERMINAL SHOULD EXPERIENCE STORMS POSSIBLY
IN A WEAKENING MODE BY 05Z TO 06Z...WITH THEM TRENDING MORE INTO THE
SHOWER MODE WITH ISOLATED THUNDER AT BRL BY 07Z OR 08Z SAT MORNING.
WILL HAVE TO WATCH FOR LOCALIZED FOG DEVELOPMENT SAT MORNING BETWEEN
WEAKENING SHOWERS. SOUTH WINDS TO RECOVER BY 16Z SAT MORNING AND CIGS
LIFT. ..12..

THE STORM PREDICTION CENTER HAS A SLIGHT RISK OF SEVERE STORMS ACROSS THE ENTIRE AREA ON SATURDAY AND SATURDAY NIGHT. THE THUNDERSTORMS ARE EXPECTED TO GENERATE ALONG A BOUNDARY WHICH WILL BE DRAPED JUST NORTH OF THE OUTLOOK AREA...AND THE GREATEST RISK OF STORMS IS NORTH OF INTERSTATE 80. THE CHANCE FOR THUNDERSTORMS CONTINUES ON SUNDAY AND SUNDAY EVENING AS A COLD FRONT DROPS SOUTHEAST ACROSS THE AREA.
