AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
340 PM CST WED FEB 19 2014

.SHORT TERM...(THIS EVENING THROUGH THURSDAY NIGHT)
ISSUED AT 339 PM CST WED FEB 19 2014

...ADJUSTED HEADLINES THIS AFTERNOON FOR BOTH FLOOD THREATS AND
THE INTENSE WINTER STORM AFFECTING THE REGION TONIGHT THROUGH
THURSDAY NIGHT...

INTENSE LOW PRESSURE DEVELOPING OVER THE CENTRAL PLAINS WILL UNDERGO
A RAPID DEEPENING PHASE AS IT LIFTS NORTHEAST THROUGH EASTERN IOWA
THURSDAY AND THURSDAY NIGHT. THIS STORM PRESENTS MULTIPLE CHALLENGES
FROM FREEZING PRECIPITATION...FLOODING...NEAR SEVERE THUNDERSTORMS...
SNOW AMOUNTS...AND FINALLY VERY STRONG WINDS IN THE WRAP AROUND
AS THE SYSTEM NEARLY BOMBS INTO THE UPPER GREAT LAKES LATE
THURSDAY NIGHT INTO FRIDAY MORNING.

OUR FORECAST CONTINUES TO FOLLOW A BLEND OF THE MORE
CONTINUED...MORE CONSISTENT GFS/ECMWF AND UKMET...LIFTING THE
SURFACE LOW FROM SE KS WHERE IT DEVELOPS THIS EVENING...THROUGH
EAST CENTRAL IA MIDDAY THURSDAY...TO S CENTRAL WI THURSDAY NIGHT.
THIS AFTERNOON...THIS STORM WAS ALREADY TAKING SHAPE IN THE FORM
OF WIDESPREAD DEEP SURFACE PRESSURE FALLS OVER NEB...KS INTO OK
AND SCATTERED SHOWERS AND THUNDERSTORM ERUPTING IN AN AREA OF
STRONG WARM ADVECTION OVER EASTERN KS ABOUT TO REACH THE KC METRO.
THIS WILL REACH INTO NE MO...SE IA AND W CENTRAL IL BEFORE
MIDNIGHT...THEN OVERSPREAD THE ENTIRE FORECAST AREA BY SUNRISE.
THE STRONG WARM ADVECTION...ELEVATED INSTABILITY AND SEASONABLY
HIGH PW VALUES WILL LEAD TO WIDESPREAD MODERATE TO SEASONABLY
HEAVY RAINFALL AND SCATTERED THUNDERSTORMS OVERNIGHT THROUGH EARLY THURSDAY.
BASED ON ELEVATED CAPES PUSHING 800 J/KG IN THE GFS AND
SUFFICIENTLY STEEP THETAE LAPSE RATES...SOME STORMS COULD PRODUCE
HAIL APPROACHING SEVERE LIMITS TONIGHT INTO THURSDAY MORNING.

WIDESPREAD QPF VALUES OF .5 TO 1 INCH FALLING OVER FROZEN SOILS AND
LINGERING SNOWPACK MAY LEAD TO FLOODING OF URBAN AND POOR DRAINAGE
AREAS...AND ALSO POSSIBLY ALONG SMALL STREAMS. THE POTENTIAL FOR
ICE JAM FLOODING APPEARS LIMITED DUE TO THE UNUSUALLY THICK NATURE
OF ICE ON AREA RIVERS. A FLOOD WATCH HAS BEEN ISSUED TO HIGHLIGHT
THE MOST LIKELY AREA FOR HEAVY RAINFALL...ACROSS NE MO...FAR SE
IA INTO W CENTRAL IL FOR LATE TONIGHT THROUGH EARLY THURSDAY
AFTERNOON WHERE LOCAL RAINFALL TOTALS COULD APPROACH 1.5 INCHES
FOR THE EVENT.

SURFACE TEMPERATURES MAY COOL BACK TO AROUND FREEZING ACROSS THE
NORTHERN TIER OF COUNTIES TONIGHT BEFORE THE PRECIPITATION BEGINS.
THIS MAY LEAD TO A PERIOD OF WINTRY MIXED PRECIPITATION AND POSSIBLE
ICE ACCUMULATION ON FROZEN SURFACES. WITH MUCH UNCERTAINTY IN
CRITICAL DETAILS AND TEMPERATURES...HAVE MENTIONED THIS MIXED PRECIP
ACROSS THE NORTH TONIGHT INTO EARLY THU WITH LIGHT ICE
ACCUMULATIONS POSSIBLE...BUT WILL HOLD OFF ON ANY HEADLINES DUE
TO THE MULTIPLE OTHER THREATS WITH THIS WINTER STORM.

THURSDAY...WIDESPREAD RAIN AND SCATTERED THUNDERSTORMS WILL CHANGE
OVER TO SNOW DURING THE AFTERNOON AS COLD AIR WRAPS AROUND THE
BASE AND SW SIDE OF THE DEPARTING CYCLONE. THIS PROCESS MAY TAKE
UNTIL LATE AFTERNOON ACROSS THE FAR EAST. QPF AMOUNTS WILL BE
LIGHTEST ACROSS THE SOUTH WHERE A DRY SLOT WILL LIFT THROUGH. IN
THE NW...THE EARLY CHANGEOVER MAY LEAD TO 2 TO 4 INCHES OF SNOW
ACCUMULATION. THIS WILL BE COMPOUNDED BY VERY STRONG WINDS
SUPPORTED BY BOTH THE GFS AND THE ECMWF AS A STRONG PRESSURE
GRADIENT BEHIND THE DEEPENING SURFACE LOW DEVELOPS OVER THE
FORECAST AREA DURING THE DAY. A DEEP TROP FOLD AND NEARLY 40 KT
WINDS AT THE SURFACE SHOWN BY THE ECMWF SUGGEST SURFACE WINDS WILL
PUSH WELL INTO ADVISORY CRITERIA AND POSSIBLY INTO HIGH WIND
CRITERIA LATE AFTERNOON INTO THURSDAY EVENING. WHILE NOT JUSTIFIED
BY EXPECTED SNOWFALL AMOUNTS...THE VERY STRONG WINDS AND HIGH
LIKELIHOOD OF BLOWING SNOW SUPPORT GOING WITH A WINTER STORM
WARNING FOR THURSDAY AFTERNOON THROUGH THURSDAY NIGHT...ROUGHLY NW
OF A LINE FROM BELLE PLAINE TO DUBUQUE. WHILE THE BULK OF THE SNOW
WILL END BY MIDNIGHT...STRONG WINDS THROUGH THE NIGHT WILL
CONTINUE WIDESPREAD BLOWING AND DRIFTING SNOW AT LEAST UNTIL
SUNRISE FRIDAY OVER MAINLY THE NORTH. AT THIS TIME...STORM TOTAL
SNOWFALL IS EXPECTED TO RANGE FROM NEAR 5 INCHES IN INDEPENDENCE
TO LESS THAN 1 INCH SOUTHEAST OF A LINE FROM SIGOURNEY THROUGH
CLINTON TO STERLING IL. TEMPERATURES WILL FOLLOW NON-DIURNAL
TRENDS THROUGHOUT...REMAINING NEAR STEADY TONIGHT IN THE 30S TO
NEAR 40...RISING TO AROUND 50 IN THE FAR SE IN THE PASSING WARM
SECTOR EARLY THURSDAY...THEN COOLING BACK TO THE MID TEENS TO MID
20S IN THE COLD AIR WRAP AROUND THU AFTERNOON THROUGH FRIDAY
MORNING.

.LONG TERM...(FRIDAY THROUGH NEXT WEDNESDAY)
ISSUED AT 339 PM CST WED FEB 19 2014

FRIDAY...PRESSURE GRADIENT RELAXES AS LOW PRESSURE DEPARTS THE REGION
ALLOWING WESTERLY WINDS TO GRADUALLY DIMINISH TO AROUND 10 MPH
DURING THE AFTERNOON. SHAVED A FEW DEGS OFF GUIDANCE ON HIGHS ACROSS
NORTHEAST IOWA WITH THE ANTICIPATION OF FRESH SNOW COVER OF SEVERAL
INCHES. COULD SEE A FAIRLY LARGE TEMP GRADIENT WITH 20S OVER THE
FRESH SNOW COVER NORTH TO 40S ACROSS THE SOUTHERN CWA. FRIDAY NIGHT
THERE IS SUGGESTIONS OF A COLD FRONTAL PASSAGE WHICH COULD BE
ACCOMPANIED BY CHANCE OF LIGHT SNOW OR POSSIBLY EVEN LIGHT RAIN
CHANGING TO SNOW. MOISTURE CONCERNS PRECLUDE MORE THAN JUST SLIGHT
CHANCE POPS ATTIM.

SATURDAY-WEDNESDAY...MAINLY DRY AND COLDER WITH RETURN TO WELL BELOW
NORMAL TEMPS. THERE IS A CHANCE OF LIGHT SNOW ARRIVING MON THROUGH
MON NGT WITH CLIPPER SYSTEM.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON)
ISSUED AT 1146 AM CST WED FEB 19 2014

VFR CONDITIONS TO PERSIST THROUGH EARLY THIS EVENING WITH SOUTHWEST
WINDS 5-10KTS SHIFTING TO SOUTHEAST. THEN...A DEVELOPING STORM
SYSTEM IN THE PLAINS WILL USHER IN HIGHER MOISTURE INTO THE AREA
WITH CONDITIONS LOWERING TO MVFR AND IFR LATE THIS EVENING AND
OVERNIGHT ALONG WITH DEVELOPMENT OF SHOWERS...WITH AT LEAST SCATTERED
THUNDERSTORMS ESPECIALLY SOUTH OF I-80 SOME OF WHICH MAY CONTAIN HAIL.
THERE IS A CHANCE OF FREEZING RAIN AT KDBQ WITH THE INITIAL ONSET OF
THE RAIN. WIDESPREAD IFR WITH AREAS OF LIFR TO VLIFR CONDITIONS
EXPECTED THURSDAY MORNING AS POTENTIAL FOR DENSE FOG WILL BE
INCREASING WITH THE ABUNDANT MOISTURE AND WINDS DIMINISHING AHEAD OF
THE LOW PRESSURE.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTH CENTRAL
ILLINOIS...NORTHWEST ILLINOIS...WEST CENTRAL ILLINOIS...EAST
CENTRAL IOWA...NORTHEAST IOWA...SOUTHEAST IOWA AND NORTHEAST
MISSOURI.

.DAY ONE...TODAY AND TONIGHT

AN INTENSIFYING AND VERY STRONG STORM SYSTEM WILL BRING WIDESPREAD
RAIN...EMBEDDED THUNDER...AND FOG THAT MAY BE DENSE...TO THE OUTLOOK
AREA TONIGHT INTO THURSDAY MORNING. WHILE NO SEVERE STORMS ARE
EXPECTED TONIGHT...A FEW MAY BE ABLE TO PRODUCE SMALL HAIL SOUTH OF
INTERSTATE 80. OF MORE OF A POTENTIAL IMPACT WILL BE SEASONABLY HIGH
WIDESPREAD RAINFALL AMOUNTS OF THREE QUARTERS OF AN INCH...UP TO AN
INCH AND A HALF...MAINLY ALONG AND SOUTH OF INTERSTATE 80 FROM
MIDNIGHT THROUGH NOON THURSDAY. THIS KIND OF RAIN AMOUNTS...AT THIS
TIME OF YEAR ON FROZEN GROUND...MAY RESULT IN SOME PONDING
ISSUES...AND URBAN AND SMALL STREAM FLOODING. THERE MAY BE A LOWER
RISK OF RIVER FLOODING DUE TO GENERALLY LOW RIVER LEVELS...BUT
SMALLER ICED UP CREEKS MAY STILL COME OUT OF THEIR BANKS IN SOME
LOCATIONS. THE THREAT OF ICE JAMMING WILL ALSO BE ON THE INCREASE
ALONG SOME AREA RIVERS AND STREAMS LATE TONIGHT...AND ESPECIALLY ON
THURSDAY.

AS RAIN SPREADS UP NORTH OF HIGHWAY 30 AFTER MIDNIGHT...THERE IS A
CHANCE THAT SOME OF IT WILL FALL AS FREEZING RAIN...ESPECIALLY ALONG
AND NORTH OF A LINE FROM DUBUQUE IOWA...TO STERLING ILLINOIS.
TEMPERATURES HOVERING RIGHT AROUND FREEZING...AND THEN WARMING ABOVE
FREEZING AFTER SUNRISE...MAY LIMIT THE ICE GLAZE POTENTIAL TO JUST A
LIGHT COATING IN THESE AREAS. SOME LOCALIZED SLICK SPOTS MAY STILL
DEVELOP HOWEVER...BEFORE TEMPERATURES RECOVER BACK ABOVE FREEZING.

MOIST AIR FLOWING OVER SNOW COVER AND COLD GROUND WILL LIKELY
PRODUCE AREAS OF FOG TONIGHT...SOME OF WHICH COULD BE DENSE AND
REDUCE VISIBILITIES TO A QUARTER MILE OR LESS. AS THE RAIN
INCREASES...IT WILL HELP REDUCE THE FOG. IN OTHER AREAS WITH
LIGHTER RAIN OR DRIZZLE...THE FOG WILL LAST WELL INTO THURSDAY.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

THURSDAY AFTERNOON AND EVENING...STRONG NORTHWEST WINDS OF 25 TO 35
MPH WILL USHER IN COLDER AIR BEHIND THE DEPARTING LOW PRESSURE
SYSTEM...CHANGING ALL PRECIPITATION TO SNOW. AT THIS TIME...IT
APPEARS THAT 1 TO 4 INCHES OF SNOW IS LIKELY NORTHWEST OF A LINE
FROM OTTUMWA TO DUBUQUE. WINDS GUSTING OVER 45 MPH MAY RESULT IN
BLOWING OF NEW SNOW...REDUCING VISIBILITIES BELOW A QUARTER MILE AT
TIMES. NEAR WHITEOUT CONDITIONS MAY BE POSSIBLE IN OPEN AND RURAL
AREAS. A WINTER STORM WATCH IS IN EFFECT FOR THURSDAY AFTERNOON
THROUGH THURSDAY EVENING GENERALLY ALONG AND WEST OF A LINE FROM
CEDAR RAPIDS TO DUBUQUE IOWA.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY OR TONIGHT.
