AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
328 PM CST WED JAN 18 2012

.SYNOPSIS...
ARCTIC COLD FRONT OVER THE PLAINS WILL SWEEP THROUGH THE REGION
TONIGHT...PROVIDING A FRESH COATING OF LIGHT SNOW...BRISK
WINDS...AND BITTER COLD TEMPERATURES AND WIND CHILLS. AT
20Z...MSAS ANALYSIS INDICATED THIS FRONT EXTENDING S-SW FROM LOW
PRESSURE OVER CENTRAL MN THROUGH SE SD INTO N CENTRAL NEB. BEHIND
THIS FRONT...TEMPERATURES WERE IN THE SINGLE DIGITS ABOVE AND
BELOW ZERO. OUT AHEAD OF THE BOUNDARY...TEMPERATURES WERE IN THE
20S AND 30S ACROSS IA AND NORTHERN IL WITH BRISK SOUTH WINDS IN AN
AREA OF TIGHTENING SURFACE PRESSURE GRADIENTS AND STRONG PRESSURE
FALLS.

&&

.SHORT TERM...TONIGHT AND THURSDAY...
PRIMARY CONCERNS ARE BITTER COLD TEMPERATURES/WIND CHILLS AND SNOW
AMOUNTS FOLLOWING THE FRONTAL PASSAGE. HAVE ISSUED A WIND CHILL
ADVISORY FOR OUR IA HIGHWAY 20 CORRIDOR FOR LATE TONIGHT THROUGH
THU MORNING.

THE FRONT IS STILL ON TRACK TO PUSH THROUGH BETWEEN 06Z AND 12Z
TONIGHT. AHEAD OF THE FRONT... SOUTHWEST SURFACE WINDS AND HIGH
CLOUDS SHOULD HOLD TEMPERATURES NEARLY STEADY IN THE UPPER TEENS
TO MID 20S THROUGH THE EVENING. BEHIND THE FRONT...TEMPERATURES
SHOULD DROP INTO THE SINGLE DIGITS TO AROUND ZERO BY
SUNRISE...ESPECIALLY OVER THE DEEPER SNOW PACK OVER THE NW HALF OF
THE FORECAST AREA. FOLLOWING THE FRONTAL PASSAGE...THERE WILL BE SEVERAL
HOURS OF 20 TO 30 MPH NW WINDS. STAYING NEAR TO BELOW THE COLDEST
MODEL SURFACE TEMPERATURE FORECASTS THAT WOULD DRIVE THE FAR NW TO
JUST BELOW ZERO BETWEEN 12Z AND 15Z...WIND CHILLS WILL LIKELY DROP
BELOW -20 CELSIUS ADVISORY CRITERIA AND HAVE POSTED AN ADVISORY
FOR BUCHANAN...DELAWARE AND DUBUQUE COUNTIES FROM 08Z THROUGH 18Z.
LINN AND BENTON COUNTIES MAY AT LEAST BRIEFLY TOUCH THIS CRITERIA
AS WELL THU MORNING.

FORECAST MODELS HAVE ALIGNED IN ROUGH AGREEMENT DEPICTING A BAND OF
ELEVATED FRONTOGENESIS THAT SETS UP OVER THE AREA FOLLOWING THE
FRONT LATE TONIGHT INTO THURSDAY MORNING. THIS IS ROUGHLY ALONG
AND NORTH OF THE 850 MB TIGHT THERMAL GRADIENT THAT IS CURRENTLY
PRODUCING SNOW ACROSS SOUTHERN MT. THIS IS SHOWN SETTING UP ROUGHLY
FROM W CENTRAL IA...E-SE ACROSS EAST OR SE IA INTO W CENTRAL IL
FROM ROUGHLY 09Z THROUGH 18Z. MOISTURE WILL AGAIN BE LIMITED...BUT
HIGHER SNOW TO LIQUID RATIOS IN THE ARCTIC AIRMASS SHOULD BE ABLE
TO MAKE THE MOST OUT OF WHAT LOOKS TO BE ONLY A FEW HUNDREDS OF AN
INCH QPF. HAVE GONE WITH LIKELY POPS FOR AXIS OF 1 TO PERHAPS 2
INCHES ACROSS AREAS ROUGHLY BETWEEN I-80 AND HIGHWAY 34 IN
IA...AND ADJACENT W CENTRAL IL. BRISK NW WINDS DURING AT LEAST
THE FIRST HALF OF THE LIGHT SNOW MAY CAUSE SOME BLOWING AND
DRIFTING...AND SOMEWHAT LIMIT ACCUMULATIONS.

FORCING QUICKLY EXITS BY MIDDAY...FOLLOWED BY DIMINISHING
WINDS AND CLEARING SKIES AS HIGH PRESSURE REBUILDS INTO THE
REGION. TEMPERATURES WILL RECOVER VERY LITTLE AND HAVE KEPT HIGHS
FROM THE SINGLE DIGITS OVER THE CURRENT DEEPER SNOWPACK ACROSS THE
NW TO THE TEENS ACROSS THE SOUTH AND SOUTHEAST. ..SHEETS..

.LONG TERM...THURSDAY NIGHT THROUGH WEDNESDAY...
A POTENT CLIPPER TYPE SYSTEM WILL AFFECT THE AREA THURSDAY NIGHT
THROUGH EARLY FRIDAY EVENING. THIS SYSTEM WILL HAVE VERY COLD AIR
ESTABLISHED AT LOW LEVELS.  NORMALLY...ONE WOULD ASSUME 20 TO 1
RATIO FOR SNOW WITH SURFACE TEMPERATURES IN THE SINGLE DIGITS TO 18
OR SO...BUT ALL MODELS DO SUGGEST A WARM WEDGE REDUCING THE OPTIMAL
DENDRITIC GROWN ZONE FOR THIS EVENT.  STILL...A FAIRLY FLUFFY 13 TO
18 TO 1 RATIO CAN BE EXPECTED.  THERE ARE TWO CAMPS IN THE
MODELS...THE ECMWF AND NAM ARE HITTING THE NORTH WITH SATURATION AND
THE SOUTH...MISSING COMPLETELY OUT. THIS DOES NOT SEEM TO CAPTURE
THE STRENGTH OF THE INCOMING ARCTIC AIR VERY WELL...AND A MORE
SOUTHERN SOLUTION AS NOTED BY THE 12Z...UKMET...GFS...GEM IS
PREFERRED.  WHILE MOISTURE IS LIMITED TO PACIFIC ORIGINS...AS ARE
ALL CLIPPERS...ALL MODELS DEPICT STRONG FRONTOGENESIS...AND ISENTROPIC
LIFT ACROSS IOWA INTO SOUTHERN WISCONSIN.  THERMALLY...THE LAYER
NEAR 600MB IS ASSOCIATED WITH THE DENDRITIC GROWTH ZONE...AND THERE
IS STRONG LIFT IN THIS SATURATED LAYER FROM 12Z FRIDAY TO 21Z OR
EVEN 00Z IN THE UKMET...GEM..AND GFS SOLUTIONS. THUS...A BAND OF
MODERATE SNOW SHOULD SET UP GENERALLY ALONG AND NORTH OF INTERSTATE
80 FRIDAY...RESULTING IN WIDESPREAD SNOW ACCUMULATION INCLUDING LATE
THURSDAY NIGHT...OF 3 TO 6 INCHES...WITH A POTENTIAL FLUFFY
ACCUMULATION OF 5 TO 8 POSSIBLE IF THE STRONGEST MODEL SOLUTIONS
VERIFY.  SINCE THERE IS STILL SOME UNCERTAINTY IN THIS STORM...AND
ONLY A STRIP OF POTENTIAL WARNING CRITERIA SNOW IS LIKELY...WE WILL
HOLD OFF ON A WINTER STORM WATCH AT THIS TIME...THOUGH WE WILL
LIKELY NEED AT LEAST AN HEAVY WORDED WINTER WEATHER ADVISORY FOR
THIS EVENT. WIND SHOULD NOT BE A MAJOR FACTOR FOR THIS EVENT...BUT
COLD TEMPS MAY ALLOW FOR REDUCED EFFECTIVENESS OF ROAD
CHEMICALS...SO THERE ARE POSITIVES AND NEGATIVES TO BE CONCERNED
WITH.

LATE THURSDAY NIGHT THROUGH SATURDAY SHOULD BE DRY AND COLD
AGAIN...WITH FRESH SNOW COVER RESULTING IN A FORECAST NEAR TO BELOW
COLDER GUIDANCE.

SATURDAY NIGHT THROUGH MONDAY...ANOTHER FAST MOVING STORM IS
FORECAST IN THE MIDWEST...WITH VERY LITTLE MODEL CONSISTENCY. AS OUR
FORECAST ATTENTION IS TURNED TO THE NEAR TERM STORMS...WE HAVE
STAYED CLOSE TO A BLENDED MODEL SOLUTION BEYOND.
..ERVIN..

&&

.AVIATION...
AN ARCTIC COLD FRONT MOVING THROUGH THE NORTHERN PLAINS THIS
AFTERNOON WILL PUSH THROUGH EASTERN IA AND NW IL LATE TONIGHT.
BRISK SOUTH WINDS AHEAD OF THE FRONT WILL DIMINISH SOME THIS
EVENING...THEN VEER TO THE WEST...THEN NORTHWEST WITH THE FRONT AS
IT PUSHES THROUGH BETWEEN 06Z AND 12Z. WITH LITTLE MOISTURE TO
WORK WITH INITIALLY...CONDITIONS WILL REMAIN VFR FROM LATE THIS
AFTERNOON THROUGH EARLY THURSDAY MORNING. IT NOW APPEARS LIKELY
THAT A BAND OF LIGHT SNOW WILL DEVELOP FROM EAST CENTRAL IA INTO W
CENTRAL IL VERY LATE TONIGHT INTO MID MORNING THURSDAY. THIS WILL
LIKELY IMPACT CID...MLI AND BRL WITH SEVERAL HOURS OF MVFR CIGS
AND VISIBILITIES. DBQ SHOULD REMAIN ON THE FRINGES OF THE SNOW
WITH ONLY FLURRIES. NORTHWEST WINDS WINDS WILL BE BRISK FROM 15
TO 25 KTS EARLY THURSDAY MORNING...RESULTING IN DRIFTING SNOW ON
RUNWAYS. ..SHEETS..

.DVN WATCHES/WARNINGS/ADVISORIES...

A CHANCE OF LIGHT SNOW TO THE OUTLOOK AREA. MOST LOCATIONS WILL
SEE A LIGHT DUSTING WITH SOME ACCUMULATIONS UP TO A HALF INCH POSSIBLE.
STRONG NORTHWEST WINDS AND FALLING TEMPERATURES WILL RESULT IN WIND
CHILLS FALLING TO 10 TO 20 BELOW ZERO TOWARD THURSDAY MORNING NORTHWEST

OF SNOW ALONG AND NORTH OF HIGHWAY 30...WITH ISOLATED HIGHER AMOUNTS
POSSIBLE. ACCUMULATIONS OF 1 TO 3 INCHES CAN BE EXPECTED ALONG THE
INTERSTATE 80 CORRIDOR WITH LESSER AMOUNTS TO THE SOUTH. HOWEVER THE
