AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
230 PM CST WED FEB 26 2014

.SYNOPSIS...
ISSUED AT 224 PM CST WED FEB 26 2014

12Z UPPER AIR ANALYSIS DEPICTED STRONG FAST MOVING SHORTWAVE DIVING SOUTH
ACROSS MANITOBA CANADA WITH 130M HEIGHT FALLS ASSOCIATED WITH IT.
130KT JET STREAK WAS ALSO NOTED WITH THIS SYSTEM. FURTHER WEST LARGE
WESTERN RIDGE STILL EXTENDS UP INTO ALASKA KEEPING THE CWA IN NW
FLOW.

18Z SURFACE ANALYSIS DEPICTED A LARGE AREA HIGH PRESSURE OVER THE
CENTRAL PLAINS CENTERED OVER SOUTHEAST KANSAS AND OKLAHOMA WITH A
COLD FRONT DROPPING SOUTH INTO THE NORTHERN PLAINS. BEHIND THIS
FRONT TEMPERATURES WERE ALREADY IN THE SINGLE DIGITS WITH STRONG
NORTHWEST WINDS GUSTING OVER 30 MPH. CLOSER TO HOME...SUNNY SKIES
AND BREEZY SOUTHWEST WINDS WERE FOUND. TEMPERATURES RANGED FROM THE
SINGLE DIGITS ABOVE ZERO NORTH TO UPPER TEENS SOUTH.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 224 PM CST WED FEB 26 2014

REST OF TODAY...BLUSTERY SOUTHWEST WINDS WITH OCCASIONAL GUSTS
OVER 30 MPH WILL BE POSSIBLE AS WE MIX OUT TO AT LEAST 900MB TODAY
AND PRESSURE GRADIENT TIGHTENS BETWEEN HIGH PRESSURE OVER THE
PLAINS AND LOW PRESSURE DROPPING SOUTHEAST ACROSS THE GREAT LAKES
REGION. SKIES WILL BE MAINLY SUNNY WITH A FEW HIGH CLOUDS MOVING
ACROSS THE NORTHERN THIRD OF THE CWA. TEMPS TO TOP OUT ONLY IN THE
LOWER TEENS NORTHEAST TO THE LOWER 20S SOUTHWEST.

TONIGHT...COLD AND WINDY CONDITIONS WILL CONTINUE WITH A DRY COLD
FRONT PASSAGE BETWEEN 9PM AND MIDNIGHT ACROSS THE CWA. WINDS TO
SHIFT TO THE NW BEHIND THE FRONT WITH GUSTS UP TO 30 MPH ONCE AGAIN
OVERNIGHT. THIS COMBINED WITH STRONG CAA (40+KTS AT 85H BRINGING IN
-15 TO -24C TEMPS) SUPPORTS WIND CHILLS DROPPING BELOW -20 DEGREES
AFTER 3AM THUS HAVE ISSUED ANOTHER WIND CHILL ADVISORY FROM 3AM-11AM
THURSDAY. LATER SHIFTS MAY BE ABLE TO DROP HEADLINE EARLY IF WINDS
DIMINISH QUICKER THAN FORECAST. LOWS SHOULD BE ABOVE RECORD LEVELS
MAINLY DUE TO THE WIND STAYING UP OVERNIGHT...WITH READINGS IN THE
SINGLE DIGITS ABOVE AND BELOW ZERO BY MORNING.

THURSDAY...DRY BUT COLD CONDITIONS WILL BE SEEN AS A LARGE 1028 MB
HIGH DROPS SOUTHEAST INTO THE MIDWEST OUT OF CANADA. NORTH TO
NORTHWEST WINDS WILL KEEP TEMPS FROM RISING MUCH THROUGHOUT THE DAY
DESPITE SUNNY SKIES.  READINGS WILL ONLY REACH THE SINGLE DIGITS
ACROSS THE NORTHERN TWO THIRDS OF THE CWA TO THE MIDDLE TEENS OVER
THE FAR SOUTH. THESE READINGS WILL BE CLOSE TO THE RECORD COLD HIGHS
FOR MLI/DBQ AND HAVE INCLUDED THESE IN THE CLIMATE SECTION BELOW.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 224 PM CST WED FEB 26 2014

THE LONG TERM REMAINS ACTIVE WITH AT LEAST TWO POTENTIAL SNOW
SYSTEMS...BUT MORE THAN ANY OTHER FEATURE IS SHOULD REMAIN MUCH
BELOW NORMAL. THE COLD REGIME IS FORECAST BY ALL OPERATIONAL
MODELS...WHICH SHOW A HIGH CONFIDENCE SCENARIO OF SYNOPTICALLY
SUPPORTED ARCTIC COLD IN THE MIDWEST THROUGH THE END OF NEXT WEEK.
AS EACH DAY THIS PATTERN LINGERS ON...IT WILL REPRESENT WEATHER
FARTHER AND FARTHER FROM NORMAL. NORMAL HIGHS TODAY ARE AROUND 40
WITHIN OUR CWA...AND BY DAY 7 ARE IN THE LOWER 40S...OUR FORECAST
WILL COMMONLY REPRESENT LEVELS 20 TO 30 DEGREES COLDER THAN THAT.

TWO SNOW EVENTS LOOK TO IMPACT THE REGION...THE FIRST BEING FRIDAY
AFTERNOON THROUGH FRIDAY NIGHT...AND THE NEXT GENERALLY SATURDAY
AFTERNOON THROUGH SUNDAY. MODELS DO NOT SHOW A CLOSED CIRCULATION
ALOFT FOR EITHER EVENT...THUS BOTH ARE PRIM ARLY DRIVEN THROUGH
MODEST WAA AND FRONTOGENESIS. THIS INDICATES MAINLY A LIGHT SNOW
INTENSITY FOR BOTH EVENTS. THE INITIAL EVENT FRIDAY PM SHOULD
BEGIN IN THE WEST AFTER NOON...AND SLOWLY MIGRATE EAST OF THE CWA
LATE FRIDAY NIGHT. SNOW SHOULD LAST AROUND 8 HOURS OR SO IN ANY
ONE LOCATIONS...WITH LIGHT INTENSITY. THIS SUPPORTS AMOUNTS OF 1
TO 2 INCHES IN GENERAL FROM THE INITIAL EVENT. THE GFS IS THE ODD
MODEL OUT OF THIS PROCESS WITH RESPECT TO QPF. THIS IS MAINLY DUE
TO THAT MODEL SHOWING MORE NOTABLE CONVECTIVE/SHOWERY
PRECIPITATION OVER MISSOURI AND SOUTHERN ILLINOIS FRIDAY...WHICH
PREVENTS MOISTURE FROM REACHING THE NORTHERN WAVES FORCING OVER
IOWA. THIS IS POSSIBLE BUT NOT GIVEN OUR SUPPORT...HOWEVER A NOD
TO THIS WILL KEEP POPS IN THE LOWER END OF LIKELY FOR THE 1ST
EVENT.

QUICKLY ON THE HEALS OF THE FIRST EVENT WILL BE ANOTHER PRIMARILY MID
LEVEL FRONTOGENESIS EVENT FOR SATURDAY INTO SUNDAY. ALL MODELS SHOW
A ZONE OF LIGHT SNOW FORMING OVER NORTHERN IOWA AND SOUTHERN SOUTH
DAKOTA SATURDAY...WORKING SLOWLY EAST AND SOUTH THROUGH SUNDAY. THIS
SHOULD BRING SNOW OVER THE ENTIRE CWA DURING THE SATURDAY PM TO
SUNDAY PERIOD...WITH LIGHT TO BRIEFLY MODERATE INTENSITY EXPECTED.
SNOW AMOUNTS WILL BE DETERMINED BY HOW LONG THE BAND OF SNOW REMAINS
OVER HEAD. THE GFS IS SLOWEST...AND THEREFORE HEAVIEST ON SNOW
TOTALS. OTHER MODELS SUCH AS THE ECMWF REMAIN QUICKER AND LIGHTER.
AS WE RESOLVE TIMING...WE CAN DETERMINE THE SCALE OF THIS SNOW
EVENT/AMOUNTS.

AT THE SURFACE...STRONG ARCTIC HIGH PRESSURE SHOULD BE IN CONTROL
THROUGH THE ENTIRE FORECAST. THUS...AFTER HIGHS FRIDAY IN THE 20S TO
LOWER 30S...WE SHOULD REMAIN IN THE TEENS TO LOWER 20S FOR HIGHS
THROUGH NEXT WEDNESDAY...WITH LOWS OF -10 TO +5 OVER THE CWA THROUGH
THE PERIOD. WIND MAY BE STRONG ENOUGH FOR WIND CHILL ADVISORY
CONDITIONS MONDAY AND TUESDAY...AND WILL NEED TO BE WATCHED ALSO FOR
BLOWING/DRIFTING SNOW POTENTIAL. MARCH WILL BEGIN MUCH LIKE JANUARY
DID 2 MONTHS AGO.
