AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
332 PM CDT FRI OCT 10 2014

.SYNOPSIS...
ISSUED AT 327 PM CDT FRI OCT 10 2014

LATEST SFC ANALYSIS WAS INDICATING SEASONABLY STRONG MAIN RIDGE
CENTER FROM ACRS NORTH CENTRAL NEB...EASTERN SD INTO CENTRAL
MN...BUT THE ENTIRE RIDGE COMPLEX WAS OCCUPYING MUCH OF THE NORTH
HALF OF THE PLAINS AND UPPER MIDWEST/NW GRT LKS. THE PRIME LLVL
BAROCLINIC BATTLE ZONE WAS LOCATED TO THE SOUTH OF THIS FEATURE FROM
ACRS OK...THE MO/AR BORDER REGION...AND UP THE OH RVR VALLEY. WHILE
ANY OVERRUNNING PRECIP SUCH AS THAT OUT ACRS FAR NORTHEASTERN KS
SHOULD STAY SOUTH OF THE DVN CWA THIS EVENING...THE LARGER SCALE
OVERRUNNING PROCESS AND LIFT OFF RIGHT ENTRANCE REGION OF GRT LKS
UPPER JET MAX HELPING DRAW UNDULATING ROUNDS OF CI CLOUDS ACRS MUCH
OF THE CWA...THICKER AS YOU GO SOUTH. WATER VAPOR IMAGERY ALSO
INDICATING AN UPPER LEVEL WAVE IN TROF BASE ACRS KS INTO CENTRAL
MO...WITH THIS EDDY TO CONTINUE TO DIG EAST-SOUTHEAST OVERNIGHT.

&&

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 327 PM CDT FRI OCT 10 2014

TONIGHT...MAIN CHALLENGE IS HOW COLD TO GO AND ISSUANCE OF FROST/
FREEZE HEADLINES. UNDER CLEAR SKIES AND LIGHT TO CALM WINDS...TEMPS
RIGHT UNDER THE RIDGE CENTER ACRS THE CENTRAL INTO EASTERN DAKOTAS
AND WESTERN MN DIPPED INTO THE MID TO UPPER 20S EARLY THIS MORNING.
THIS SAME RIDGE CENTER IS EXPECTED TO SLIDE JUST WEST AND NORTH OF
THE CWA BY SAT MORNING FROM JUST NORTHWEST OF DSM...THROUGH THE
MN/WI/IA TRI-STATE REGION AND ACRS NORTHEASTERN WI. THUS WOULD
EXPECT COLDEST TEMPS/MID TO UPPER 20S AND SOLID HARD FREEZE BY SAT
MORNING IN THESE SAME AREAS. BUT WITH LIGHT LLVL NORTH TO NORTHEAST
FLOW FROM THIS SOURCE REGION OVERNIGHT AND DRY SFC DPT FETCH...THE
NORTHERN THIRD OR A BIT MORE OF THE DVN CWA MAY BE IN LINE FOR AT
LEAST A MARGINAL FREEZE OF UPPER 20S TO LOWER 30S. THE CENTRAL INTO
SOUTHERN DVN CWA WITH LOW TO MID 30S A GOOD FROST BET...WHILE THE
FAR SOUTHERN CWA MID TO UPPER 30S WITH JUST SOME PATCHY FROST. ALL
THIS DEPENDS ON THE CIRRUS THINNING/CLEARING BY MIDNIGHT OR 1 AM
CDT...ALONG WITH SFC WIND DECOUPLE. BUT THE FLY IN THE OINTMENT IS THAT
THE CIRRUS MAY HANG ON LONGER THAN THE MODELS SUGGEST...PLUS
IN-BUILDING RIDGE GRADIENT MAY KEEP NORTH TO NORTHEAST SFC WINDS AT
3-6 MPH GOING ACRS PORTIONS OF THE AREA INTO EARLY SAT MORNING. BUT
WITH THE COLD LOOMING HIGH JUST TO THE NORTH AND OTHER SIGNALS THAT
CAN/T BE IGNORED...WILL PLAY IT SAFE AND ISSUE A FREEZE WARNING
LATE TONIGHT ALONG AND NORTH OF AN IOWA COUNTY...TO CEDAR/CLINTON
AND ACRS CARROLL COUNTY IL LINE. A FROST ADVISORY TO THE SOUTH OF
THAT LINE FOR ALL BUT THE FAR SOUTHEASTERN QUARTER OF THE DVN
CWA...BUT EVEN THOSE AREAS WITHOUT ANY HEADLINE MAY STILL GET AT
LEAST PATCHY FROST...IF THE CIRRUS CLEARS. THOSE SOUTHERN AREAS THE
BEST CHC OF CIRRUS HANGING ON INTO SAT MORNING.

SATURDAY...AFTER A CHILLY START TO THE DAY...PLENTY OF SUNSHINE/
ALTHOUGH THE FAR SOUTH MAY STILL BE FILTERED BY SOME CIRRUS/ AND
MIXING UP INTO BASE OF INVERSION WILL STILL MAKE FOR WIDESPREAD
AFTERNOON TEMPS IN THE UPPER 50S TO LOWER 60S AND A FINE FALL DAY
WITH RATHER LIGHT WINDS.    ..12..

.LONG TERM...(SATURDAY NIGHT THROUGH NEXT FRIDAY)
ISSUED AT 327 PM CDT FRI OCT 10 2014

MODERATE TO LOWER END HEAVY RAIN EVENT EARLY NEXT WEEK THE MAIN
FORECAST ISSUE.

LONG TERM FORECAST CONFIDENCE ASSESSMENT...OVERALL FAIR OR AVERAGE
WITH RAIN TOTALS THE MAIN FORECAST UNCERTAINTY QUESTION.  TRENDS PAST
24 HOURS HAVE CONTINUED AS DISCUSSED PAST 2 DAYS IN LINE WITH FURTHER
NORTH AND STRONGER ECMWF AND UKMET.  CLEAR EVIDENCE OF STRENGTHENING
AND OCCLUDING LOW PRESSURE SYSTEM TO PASS JUST SOUTHEAST OF AREA WITH
A DEFORMATION ZONE. MAGNITUDE OF OCCLUSION BETTER CONFIRMED NEXT 12-
24 HOURS WITH HIGHER POPS POSSIBLE IN DEFORMATION ZONE AND WHERE THE
TRACK IS BETTER CONFIRMED THE NEXT 24 HOURS.

OVERVIEW...INITIALIZATION EXCELLENT ON LARGE SCALE SYNOPTIC SCALE
KINEMATIC FEATURES AND UPSTREAM IN PACIFIC.  SOLUTIONS ANALYSIS OF
RUN TO RUN VARIANCE AND VERIFICATION AT 18Z SHOWS TIGHTER SUITE OF
OUTPUT AND THIS LESS MEANS UNCERTAINTY EXCEPT QPF AMOUNTS.  LOCAL
TECHNIQUES INFER A 60/40 MIX OF HI-RES ECMWF/UKMET WITH GFS/GEM-NH.

SATURDAY NIGHT...DELAY IN CLOUDS HAVE LOWERED LOWS AS WAS CONCERN
YESTERDAY WITH MID/UPPER 30S NORTH AND LOWER 40S SOUTH SECTIONS.
CLOUDS TO INCREASE IN FAR SOUTH TOWARD MORNING.  HAVE REMOVED POPS
DUE TO STRONGER AND SLOWER NATURE OF UPPER LEVEL STORM SYSTEM. LIGHT
EAST WINDS MAY ALLOW FOR PATCHY FROST NE SECTIONS.

SUNDAY...SKIES TO BECOME MOSTLY CLOUDY BY MID PM WITH WEAK UPPER
LEVEL DISTURBANCE TO BRING SPOTTY SPRINKLES AND ISOLATED LIGHT
SHOWERS WITH MOSTLY LOW CHANCE POPS SE 1/2 OF AREA. ANY RAIN AMOUNTS
SHOULD BE MOSTLY 5 HUNDREDTHS OF AN INCH OR LESS. RAISED HIGHS
DUE MORE SUNSHINE TO AROUND 60 DEGREES WITH SOME LOCATIONS POSSIBLY
REACHING LOWER 60S FOR LATER SHIFTS. SUNDAY NIGHT...CLOUDY WITH AREA
OF RAIN AND RAIN SHOWERS AND POSSIBLY SOME DRIZZLE AND LIGHT FOG
ARRIVING WITH MAIN LOW PUSHING MAIN PRECIPITATION INTO SW SECTIONS
AROUND MORNING...HAVE KEPT LIKELY POPS THERE.  VERY MINOR CHANGES IN
LOWS...IN THE UPPER 40S NORTH TO LOWER 50S CENTRAL AND SOUTH.

MONDAY AND TUESDAY...MAIN STORM SYSTEM TO OCCLUDE AND MOVE SLOWLY
NORTHEAST OR AREA LATE TUESDAY.  LOW TRACK ALONG A UIN-VYS-MKE LINE
NEAR IDEAL FOR WIDESPREAD RAIN AND DEFORMATION ZONE OVER ALL BUT FAR
EASTERN SECTIONS IN ILLINOIS.  LOCAL HEAVY RAIN TOOLS SUGGEST THE
REGION WITH PW/S .8 TO 1.25+ INCHES TO SEE WITH DEFORMATION ZONE
MOSTLY THREE QUARTERS OF AN INCH TO AROUND 1.5 INCHES OVER A 24-36
HOUR PERIOD.  IF OCCLUSION IS A BIT TIGHTER...LOCALIZED 2+ INCHES
SUGGESTED...BUT LITTLE RISK OF WATER ISSUES AS SHOULD OCCUR AGAIN
OVER A 24 TO 36 HOUR PERIOD AND GROUND IS DRY.  CURRENT FORCING
TOOLS SUGGEST HEAVIEST RAINS SHOULD BE +/- 30 NM EITHER SIDE OF A
DBQ-IOW-OTM LINE.  AGAIN THIS SHOULD BE BETTER KNOWN THIS TIME
SATURDAY WHERE HEAVIEST RAIN TOTALS TO OCCUR AND STRENGTH OF THE
DEFORMATION ZONE. HIGHS MID/UPPER 50S IN NW TO W SECTIONS AND MOSTLY
LOWER 60S SE SECTIONS.  MINS MID TO UPPER 40S TUE/WED AM.  ENOUGH
ELEVATED INSTABILITY NEAR SFC LOW TRACK FOR ISOLATED THUNDER OVER SE
1/4 OF FORECAST AREA.

WEDNESDAY THROUGH FRIDAY...CLEARING WEDNESDAY WITH POSSIBLE LINGERING
MORNING SHOWERS.  THEN...FAIR AND DRY.  ZONAL FLOW SUPPORTS NEAR
NORMAL TEMPERATURES WITH HIGHS IN THE MOSTLY IN THE LOWER 60S
WEDNESDAY AND A BIT WARMER THURSDAY/FRIDAY IN THE MID 60S.  LOWS IN
THE 40S.    NICHOLS
