AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
330 PM CST MON DEC 17 2012

.SYNOPSIS...
LIGHT WINDS AND LINGERING LOW LEVEL MOISTURE HAS KEPT LOW CLOUDS AND
LIGHT FOG IN PLACE TODAY ACROSS THE FORECAST AREA. AS A RESULT...
TEMPERATURES HAVE STRUGGLED TO CLIMB...HAVING ONLY REACHED THE UPPER
20S NORTH TO MID 30S SOUTH THIS AFTERNOON. MSAS ANALYSIS INDICATED A
RIDGE OF HIGH PRESSURE REACHED FROM TX TO MN...FLANKED BY LOW
PRESSURE MOVING ALONG A COLD FRONT IN NORTHERN KY TO THE SE...AND A
LEE TROUGH REACHING FROM NORTHERN MT TO EASTERN CO. IN THE UPPER
LEVELS...A TROUGH AXIS REACHED FROM THE EASTERN DAKOTAS TO THE MO
BOOTHEEL REGION. UPSTREAM...12Z ANALYSIS INDICATED A 160 KT JET AT
300 MT MOVING IN THE STRONG...NEARLY ZONAL FLOW...ACROSS NORTHERN CA
INTO THE GREAT BASIN REGION. AN UPPER LOW WAS OFF THE NORTHERN BC
COAST WITH A TROUGH AXIS EXTENDING S-SW INTO THE PACIFIC.

&&

.SHORT TERM...TONIGHT AND TUESDAY...
DEVELOPING ACTIVE PATTERN WILL SEND ANOTHER ROUND OF PRECIPITATION
THROUGH THE REGION TONIGHT INTO EARLY TUESDAY. FORECAST CHALLENGES
CENTER ON THIS PRECIPITATION LATE TONIGHT INTO TUESDAY...ALONG WITH
LOW CLOUDS AND FOG.

LATEST VISIBLE SATELLITE IMAGES SHOW AN AREA OF CLOUDS OVER NORTH
CENTRAL MO INTO SOUTHERN IA...SLOWLY MIGRATING EASTWARD WITH THE
UPPER LEVEL TROUGH. AS THIS EXTENDS EASTWARD INTO THE SOUTHERN THIRD
OF THE FORECAST AREA AROUND SUNSET...THERE WILL BE A POTENTIAL FOR
THICKENING OF THE FOG THAT HAS LINGERED OVER SE IA AND ADJACENT
AREAS OF MO AND IL THIS EVENING. BASED ON LATEST RAP LOW LEVEL
MOISTURE FIELDS...STRATUS WILL LIKELY REMAIN IN PLACE THROUGH THE
NIGHT OVER THE REMAINDER OF THE FORECAST AREA...AND LIKELY FILL BACK
IN ANY HOLES THAT DEVELOP ACROSS THE SOUTH. WILL GO WITH PATCHY FOG
WORDING FOR NOW AND MONITOR THE SOUTH THIS EVENING FOR POSSIBLE
UPDATES TO MORE DENSE OR WIDESPREAD COVERAGE. A STRIKE AGAINST FOG
TONIGHT WILL BE THE INCOMING SUBSIDENCE BEHIND THE UPPER LEVEL WAVE
AND INCREASING WINDS TOWARD MORNING AS A SURFACE LOW APPROACHES.
AS SEEN TODAY...CLOUDS...LINGERING MOISTURE AND WEAK WINDS WILL
LIMIT DIURNAL TEMPERATURE CURVES AND HAVE KEPT MINS CLOSE TO CURRENT
DEWPOINTS...FROM THE MID 20S NORTH TO LOWER 30S SOUTH.

THE FOCUS THEN TURNS TO AN IMPULSE IN THE FAST ZONAL FLOW ALOFT THAT
WAS MOVING ACROSS CENTRAL ID AT MIDDAY. MODELS DEVELOP THIS INTO A
CLIPPER LIKE LOW PRESSURE SYSTEM AS THE ENERGY MOVES OVER THE LEE
TROUGH TONIGHT. THIS FAST MOVING LOW DEVELOPS OVER NEB LATE
TONIGHT...THEN HEADS EASTWARD OVER THE FORECAST AREA DURING THE
DAY TUESDAY. HAVE GENERALLY FOLLOWED A BLEND OF THE GFS/ECMWF AND
GEM WITH THIS FEATURE...WHICH DEVELOPS A NW TO SE ORIENTED WARM
ADVECTION WING OF LIGHT SNOW OVER THE CENTRAL PART OF THE FORECAST
AREA BETWEEN 06Z AND 12Z AND HAVE KEPT CHANCE POPS THERE. THE
POTENTIAL FOR LIGHT SNOW OR FLURRIES SHOULD THEN SHIFT TO THE FAR
NORTH AND NORTHEAST BY AFTERNOON AS THE LOW MOVES TOWARD CHICAGO.
WITH LIMITED MOISTURE AND RAPID PROGRESSION...SNOWFALL AMOUNTS
SHOULD BE WELL BELOW AN INCH IN MOST LOCATIONS WITH THE BEST CHANCES
OF A LIGHT COATING NORTH OF THE HIGHWAY 30 CORRIDOR. HAVE TRENDED
SOME PARTIAL CLEARING FROM SW TO NE IN THE AFTERNOON...BUT THIS MAY
END UP BEING TOO OPTIMISTIC DUE TO THE LINGERING MOISTURE AND
CYCLONIC FLOW THROUGH THE AFTERNOON. BRISK WESTERLY WINDS IN THE FAR
SOUTH MAY ALLOW TEMPERATURES TO REACH THE UPPER 40S...WHILE HIGHS IN
THE NORTH ARE KEPT IN THE UPPER 30S.

.LONG TERM...TUESDAY NIGHT THROUGH NEXT MONDAY...
ALL LONG TERM FCST ENERGY INTO HANDLING MIDWEEK STORM SYSTEM...WITH
THE WEEKEND LOOKING IN BETWEEN SYSTEMS AND RATHER BENIGN/SEASONABLE
ANYWAY THROUGH EARLY MONDAY. ASSESSING THE LATEST 12Z MEDIUM RANGE
MODEL RUNS AS WELL AS THE NAM...SURPRISINGLY GOOD AGREEMENT WITH
GENERAL SFC LOW AND MID LEVEL LOW PATHS BUT WITH SOME TRACKING
SPEED AND STRENGTH VARIANCES. THIS TAKING INTO ACCOUNT BULK OF WAVE
ENERGY THAT WILL DRIVE THE STORM STILL OFF THE PACIFIC NORTHWEST
COAST AND SOUTH OF THE GULF OF AK. ALL MODELS BUT THE 12Z ECMWF THAT
IS. WHILE THE OTHERS HAVE TRENDED FURTHER NORTH AND WEST WITH THEIR
LATEST 12Z RUNS WHICH MAKE FOR MORE OF A PRECIP TYPE/AMOUNT CHALLENGE
FOR THE DVN CWA...THE CONSISTENT ECMWF WOULD STILL IMPACT MOST OF THE
LOCAL FCST AREA WITH A QUICKER SWITCH OVER TO SNOW AND MORE AREAS
STARTING OFF AS SNOW TO BEGIN WITH. THE ENSEMBLE SFC LOW TRACK OF
THE 12Z GFS/NAM/UKMET/GEM ALL HOOK THE DEVELOPING LOW FROM THE OK
PANHANDLE ON WED UP THROUGH NORTHEAST MO/WEST CENTRAL IL LATE WED
NIGHT...TO A NORTH CENTRAL IL POSITION BY THU MORNING...AND THEN
BOMB IT OUT ACRS LOWER MI INTO THU EVENING. THE 12Z EURO MAINTAINS
A TRACK FURTHER TO THE SOUTHEAST OF THE ENSEMBLE PATH...SOUTHWEST MO
TO NEAR THE STL AREA BY THU MORNING AND THEN OFF TO WEST CENTRAL
INDIANA BY EARLY THU AFTERNOON. THE ENSEMBLE OF SOLUTIONS BESIDES THE
ECMWF WOULD GENERALLY SUGGEST MUCH OF THE SOUTHEAST HALF TO TWO
THIRDS OF THE FCST AREA TO BE RAIN OR EVEN EXPERIENCE SOME
CONVECTION THROUGH MIDNIGHT WED NIGHT...WHILE THE NORTHWEST THIRD
MIXES AND DYNAMICALLY COOLS INTO WET ACCUMULATING SNOW AFTER 03Z
THU. AS DEF ZONE CONTINUES TO FORM AND LLVL COLD CONVEYOR IN-WRAPS
AND INCREASES...THESE MODELS GENERALLY SUGGEST THE SWITCH OVER TO
WET SNOW TO CONTINUE FROM WEST-NORTHWEST TO THE EAST AFTER MIDNIGHT
AND INTO EARLY THU MORNING ACRS THE DVN CWA. 3-7 INCHES POSSIBLE BY
12Z THU ALONG AND WEST OF A LINE FROM SIGOURNEY IA...TO EAST OF
CEDAR RAPIDS AND TO WEST OF DBQ. SOME ADDITIONAL ACCUMS OF 1-2
INCHES IN THESE AREAS POSSIBLE THROUGH 18Z THU...BUT BULK OF
ACCUMULATING SNOW TO SWITCH EASTWARD ACRS THE REST OF THE CWA WITH 3-
6 INCHES POSSIBLE ALONG AND NORTH OF A LINE FROM MT PLEASANT IA...TO
THE QUAD CITIES..AND TO STERLING IL.

WHILE THE NORTHWEST THIRD AND NORTH CENTRAL PORTIONS OF THE DVN CWA
MAY EVENTUALLY GET 4-8+ INCHES BY THU EVENING...THE ENSEMBLES MINUS
THE ECMWF SUGGEST THE HIGHEST SNOWFALL TOTALS OF 8-12+ INCHES OCCUR
WEST AND NORTH OF THE DVN CWA ACRS SOUTH CENTRAL IA...UP THROUGH
NORTHEASTERN IA INTO SW/CENTRAL WI. EXTENT OF BOMBING CYCLONE TO THE
EAST STILL INDICATED BY BULK OF THE MODEL RUNS TO DRIVE VERY STRONG
NORTH BECOMING NORTHWEST WINDS LATE WED NIGHT AND ESPECIALLY ON
THU...SUSTAINED 25 TO 35 MPH WITH GUSTS TO AT LEAST 45 MPH. GRAVITY
WAVE PHENOMENA WEST OF RAPIDLY DEEPENING CYCLONE COULD ALSO PRODUCE
ISOLATED GUSTS OVER 50 MPH AT MAX DEEPENING STAGE ON THU. THUS WHERE
ACCUMULATING SNOWS OCCUR...NEAR BLIZZARD OR BLIZZARD CONDITIONS VERY
POSSIBLE. BACK TO THE ECMWF...IT/S TRACK WOULD MEAN MORE OF A DIRECT
HIT UPON THE LOCAL AREA AND HIGHER SNOW AMOUNTS FURTHER EAST AND
SOUTH...ESPECIALLY TAKING INTO ACCOUNT SOME FUJI-WARA EFFECT OF
SECONDARY VORT INTERACTING IN TROF BASE AND ENHANCING DEF ZONE SNOWS
ACRS THE LOCAL AREA ON THU. DESPITE ONGOING MODEL UNCERTAINTY AND
THE SYSTEM TO BE BETTER SAMPLED FOR THE 00Z RUNS TONIGHT AND
ESPECIALLY 12Z TUE...WILL ISSUE A WINTER STORM WATCH FOR ROUGHLY THE
NORTHWEST HALF OF THE DVN CWA FOR WED NIGHT AND THU GIVING A NOD
SOMEWHAT TO THE ENSEMBLE TRACK. THE STRONG WINDS LOOK TO BE A LARGE
IMPACT EVEN FOR ADVISORY LEVEL OR SLIGHTLY LESS SNOW AMOUNTS. DO FEEL
THE CWA WILL HAVE TO EVENTUALLY BE DIVIDED INTO WINTER STORM WARNING
AND ADVISORY AREAS...BUT WHERE AN WHEN STILL UP IN THE AIR. A
WATCHFUL EYE WILL ALSO NEED TO BE OPEN FOR TRENDS ON THE NEXT 1-2
MODEL RUNS BACK CLOSER TO THE CONSISTENT ECMWF...WHICH WOULD THEN
WARRANT THE NEED OF EXPANDING THE WATCH SOUTH AND EAST.     ..12..

.AVIATION...
STRATUS AND FOG WILL LIKELY REMAIN IN PLACE TONIGHT...WITH LATEST
TRENDS NOW SUGGESTING LIGHT SNOW OR FLURRIES MAY IMPACT CID...DBQ
AND POSSIBLY MLI TOWARD DAWN TUESDAY. LINGERING LOW LEVEL MOISTURE
AND LIGHT WINDS WILL CONTINUE IFR AND POSSIBLE LIFR CONDITIONS DUE
TO LOW CIGS AND FOG THROUGH THE NIGHT. A FAST MOVING LOW PRESSURE
SYSTEM MOVING OUT OF THE ROCKIES WILL SPREAD LIGHT SNOW OR FLURRIES
ACROSS EASTERN IA AND NW IL LATE TONIGHT AND INTO TUESDAY MORNING.
CONFIDENCE IS INCREASING THAT THIS PRECIPITATION MAY AFFECT AT LEAST
THE DBQ TERMINAL...AND THIS WILL LIKELY BE REFLECTED IN UPDATES THIS
EVENING. OTHERWISE...CURRENT FORECASTS HAVE CONDITIONS IMPROVING TO
MVFR AFTER SUNRISE TUESDAY.    SHEETS
