AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
151 PM CST WED JAN 22 2014

.DISCUSSION...
320 AM CST

TODAY THROUGH TONIGHT...
WHEN TRYING TO DESCRIBE THE CURRENT WEATHER PATTERN...IT IS SIMILAR
TO A CAR STUCK IN NEUTRAL. THE ENGINE STARTS UP...BUT DOESN'T GO
ANYWHERE. MOTHER NATURE CLEARLY HAS DECIDED TO LOCK THE REGION
INTO A COLD PATTERN...WITH NO SIGNIFICANT PATTERN CHANGE PROGGED FOR
AT LEAST THE NEXT 10 DAYS. SO IF YOU ENJOYED THE PAST SEVERAL
WEEKS...GOOD NEWS...IT WILL LIKELY CONTINUE. ALAS WE ARE WITHIN TWO
WEEKS OF SEEING WHAT A SPECIAL GROUNDHOG WILL PREDICT.

THIS MORNING WILL BEGIN RELATIVELY QUIET...HOWEVER THIS WILL MERELY
BE A TEASE AS A CLIPPER CENTERED OVER THE UPPER MIDWEST EARLY THIS
MORNING WILL ARRIVE ACROSS WISC SPREADING LIGHT SNOW TO THE SOUTH
LATER THIS MORNING...AND PERSIST THROUGH THE AFTERNOON HOURS. THE
DYNAMICS WITH THIS NEXT WAVE HAVE STRENGTHENED MARGINALLY...WITH A
NARROW CHANNEL OF MOISTENING/ASCENDING PARCELS INTO A FAVORABLE DGZ.
THE BEST AREA FOR LIGHT ACCUMUS WILL BE FOCUSED ALONG AND NORTH OF A
DIXON TO KANKAKEE TO FOWLER LINE...WITH GENERALLY 0.5 TO 1.0
SNOWFALL. SOUTH OF THIS LINE UP TO ONE HALF INCH IS
POSSIBLE...MEANWHILE A NARROW AREA IN EXTREME NORTHEAST IL COULD SEE
UP TO 2.0 INCHES OF FRESH POWDERY SNOWFALL BY LATE THIS AFTERNOON.

GUIDANCE CONTINUES TO INDICATE TEMPS WILL WARM INTO THE LOW TO UPPER
TEENS THIS AFTN...HOWEVER FEEL THIS MAY BE A BIT OVERDONE GIVEN THE
LINGERING POTENT THERMAL RIDGE OVERHEAD. THE CAVEAT WILL BE THAT
TEMPS EARLY THIS MORNING HAVE ALREADY BEGUN TO WARM WITH WINDS
HAVING BECOME SOUTHERLY. SO FOR NOW WILL HOLD ONTO THE LOW TO UPPER
TEENS.

CLIPPER WILL PUSH INTO WESTCENTRAL LOWER MICHIGAN LATE THIS
AFTN/EARLY EVE...WITH A FRONTAL BNDRY SLIDING EAST ACROSS NORTHERN
IL AND VEERING SOUTHERLY WINDS TO WEST/NORTHWEST BY THIS EVENING. A
SHARP INCREASE IN THE PRES GRADIENT AS A STRONG ANTI-CYCLONIC
FEATURE SLIDES SOUTH FROM CENTRAL CANADA INTO THE NORTHERN/CENTRAL
PLAINS OVERNIGHT. THIS WILL PRODUCE BLUSTERY CONDITIONS...AND
UNFORTUNATELY WITH TEMPS FALLING INTO TO ARND 0 NEAR LAKE MICHIGAN
AND WELL BELOW ZERO FOR AREAS WEST OF I-355. THE COMBINATION OF
GUSTY WINDS OVERNIGHT BETWEEN 30-35 MPH AND FORECAST TEMPS...WIND
CHILL VALUES ARE EXPECTED TO FALL TO ARND -20 TO -25 TONIGHT. GIVEN
THE CONSISTENCY IN FORECAST TEMPS/WINDS...HAVE OPTED TO GO AHEAD AND
ISSUE THE WIND CHILL ADVISORY FOR TONIGHT THROUGH THURSDAY MORNING.

CONFIDENCE IN WIND CHILL ADVISORY/FORECAST...HIGH.

THURSDAY THROUGH FRIDAY...
WHILE THE CLIPPER WILL BE WELL EAST OF THE REGION...THE EFFECTS WILL
LINGER WITH CLOUDS HOLDING THRU THUR MORNING BEFORE THE STRONG SFC
RIDGE OVER THE CENTRAL CONUS BEGINS TO ERODE THE LINGERING MOISTURE
BY THE AFTN HOURS. COLD AIR WILL CONTINUE TO ADVECT SOUTHEAST ACROSS
THE CWFA THUR...WITH TEMPS STRUGGLING TO WARM BEYOND THE SINGLE
DIGITS ABOVE ZERO. COULD SEE A FEW AREAS IN THE FAR WESTERN CWFA
STRUGGLE TO WARM BEYOND A FEW DEGREES BELOW ZERO THUR. WINDS WILL
CONTINUE TO BE GUSTY AT TIMES DURING THE DAY THUR...HOWEVER NOT AS
POTENT AS THE EARLY MORNING HOURS. THUS IT APPEARS WIND CHILL VALUES
WILL RISE ABOVE CRITERIA TO -5 TO -15 DURING THE DAY. ALTHOUGH THIS
IS LIKELY TO BE FOLLOWED UP WITH YET ANOTHER BLUSTERY NIGHT HEADING
INTO FRI.

THE AFOREMENTIONED STRONG SFC RIDGE WILL CONTINUE TO PUSH SOUTHEAST
INTO THE MID-MISSOURI VALLEY THUR EVENING...ALLOWING THE NORTHERLY
WINDS TO BACK TO THE WEST AND EVENTUALLY SOUTHWEST. TEMPS ALOFT WILL
STEADILY WARM THROUGHOUT THE NIGHT STARTING ARND -20 DEG C TO ARND
-9 DEG C BY DAYBREAK FRI. WHICH WILL LIKELY PRODUCE A CHALLENGE FOR
SFC TEMPS...AND CURRENTLY ANTICIPATE A QUICK DROP IN TEMPS THUR EVE
BEFORE A SLOW WARMING TREND AFT MIDNIGHT. THE PRESSURE GRADIENT
RETURNS THUR NGT/EARLY FRI...WHICH WILL LIKELY BRING WIND CHILL
VALUES BACK TO AT LEAST -20 TO -25 TO POSSIBLY NEARING -30 DEG F BY
MIDNIGHT. CONFIDENCE HAS BACKED OFF ON THE WIND CHILL WARNING
CRITERIA...SO DO NOT PLAN TO HOIST ANY WIND CHILL WATCH YET.

ONCE AGAIN ANOTHER CLIPPER PUSHES EAST ACROSS MANITOBA TOWARDS JAMES
BAY FRI...WITH A TRAILING FRONTAL BOUNDARY STRETCHING THROUGH
CENTRAL IOWA. THIS BOUNDARY WILL EVENTUALLY PUSH EAST ACROSS
NORTHERN IL FRI NGT. PRIOR TO FROPA...WARM AIR WILL BE ADVECTING
NORTHEAST ACROSS THE AREA. TEMPS COULD SEE A QUICK BUMP INTO THE MID
TO POSSIBLY UPR 20S FRI...AND THAT MAY EVEN BE A TAD TOO
CONSERVATIVE. WOULD NOT BE OUT OF THE QUESTION TO SEE A HANDFUL OF
POINTS TAG 30-32 DEGREES...MAINLY SOUTH OF I-80.

GUIDANCE HAS INDICATED SLIGHTLY BETTER MOISTURE ASSOCIATED WITH THIS
LATE WEEK WAVE...INDICATING SNOW ACCUMS WILL ONCE AGAIN OCCUR. EARLY
INDICATIONS ARE THAT RATIOS WILL HOVER IN THE 20:1 TO 25:1...WITH
POSSIBLY 1-3" OF SNOW BY DAYBREAK SAT MAINLY ALONG AND NORTH OF A
DIXON IL TO FOWLER IN LINE.

CONFIDENCE IN DANGEROUSLY COLD WIND CHILLS THUR NGT...HIGH.

SATURDAY THROUGH TUESDAY...
IN THE LONG TERM PERIODS ENSEMBLES CONTINUE TO PROG MINIMAL CHANGES
TO THE CURRENT PATTERN...HOWEVER SOME MINOR RELAXING MAY TAKE PLACE
TOWARDS THE END OF THE CURRENT EXTENDED PERIODS WITH RESPECT TO THE
STRENGTH OF THE HIGH-AMPLITUDE RIDGE PARKED OVER WESTERN CANADA.

THROUGH AT LEAST MON...THE WESTERN CANADA RIDGE WILL FLIRT WITH +4
SIGMA. THIS ANOMALOUS FEATURE...COUPLED WITH A STRONG RIDGE OVER THE
CENTRAL ATLANTIC...LOCKS THE TROUGH IN PLACE FOR THE GREAT
LAKES/NORTHEAST STATES.

OPERATIONAL SOLUTIONS HAVE YET ANOTHER CLIPPER SHORTWAVE PROGGED FOR
SUN...AND PRESENTLY IS EXHIBITING POTENTIAL FOR ACCUMULATING
SNOW ACROSS THE BULK OF THE CWFA. CONFIDENCE HAS INCREASED
MARGINALLY WITH THE RECENT CYCLES BEGINNING TO HAVE SOME
CONSISTENCY. ISENTROPIC LIFT APPEARS FAVORABLE ON THE NOSE OF THE
SHORTWAVE WITH A FLATTENING IN THE MID-LVL HEIGHT FIELDS ACROSS THE
NORTHERN CWFA. THIS MAY BE AN EARLY INDICATION THAT AN FGEN BAND
COULD DEVELOP...SETTING THE STAGE FOR SEVERAL INCHES OF FRESH SNOW.
THIS SYSTEM WILL CONTINUE TO BE MONITORED.

ARCTIC AIR RETURNS FOR THE START OF NEXT WEEK...WITH TEMPS YET AGAIN
DIPPING WELL BELOW ZERO AT NIGHT AND STRUGGLING TO WARM BEYOND THE
SINGLE DIGITS ABOVE ZERO.

CONFIDENCE...HIGH
CONFIDENCE IN ACCUMULATING SNOW SUN...MEDIUM/HIGH.

* SOUTHWEST WINDS TURNING TO THE WEST/NORTHWEST THIS AFTERNOON
  WHILE INCREASING...WITH GUSTS AROUND 30KT POSSIBLE INTO THE

RODRIGUEZ

//DISCUSSION...UPDATED 18Z...

LIGHT SNOW WHICH MOVED ACROSS THE AREA THIS MORNING WILL SLOWLY
EXIT WITHIN THE HOUR...BUT WITH ANOTHER AREA OF SNOW SHOWERS
DEVELOPING INTO THE AFTERNOON WITH THE APPROACH OF A MID LEVEL
DISTURBANCE AND FRONT. THIS SNOW IS ALREADY DEVELOPING WITH
LATEST RADAR IMAGERY DEPICTING REDEVELOPMENT ACROSS SOUTHERN
WISCONSIN AND NORTHWEST ILLINOIS. ALTHOUGH DONT EXPECT THE BETTER
SHOWER DEVELOPMENT TO OCCUR UNTIL MID AFTERNOON AS COLDER AIR
MOVES ACROSS THE TERMINALS. LOWEST VISIBILITY IN THIS SNOW COULD
STILL DROP TO AROUND 1 MILE AT TIMES...BUT WITH THE PREVAILING
CONDITIONS EXPECTED TO BE AROUND 3 MILES UNTIL THIS SNOW EXITS
LATE THIS AFTERNOON/EARLY EVENING. MVFR CEILINGS WILL CONTINUE TO
DEVELOP INTO THE AFTERNOON AND LINGER OVER THE TERMINALS THROUGH
THE EVENING...AS A BULK OF THIS MVFR CLOUD COVER IS DIURNALLY
DRIVEN. DID CLEAR OUT SKIES OVER THE TERMINALS THIS EVENING AND
OVERNIGHT...AS CLOUD SHIELD APPEARS TO BE NARROW IN COVERAGE PER
LATEST SATELLITE IMAGERY.

WINDS CONTINUE TO BE ORIENTED OUT OF THE SOUTHWEST...AS LOW
PRESSURE AND ASSOCIATED FRONTAL BOUNDARIES MOVE ACROSS THE REGION.
WITH FROPA...WINDS WILL TURN TO THE WEST AND NORTHWEST WHILE
INCREASING WITH HIGHER GUSTS OF AROUND 30KT STILL EXPECTED THIS
AFTERNOON INTO THE EARLY EVENING

RODRIGUEZ

.MARINE...
339 AM CST

A VERY ACTIVE WEATHER PATTERN IS IN STORE FOR THE FORESEEABLE
FUTURE ACROSS THE GREAT LAKES REGION...AND THIS WILL LIKELY RESULT
IN SEVERAL HEADLINE WORTHY WIND EVENTS ACROSS THE LAKE.

ANOTHER CLIPPER SYSTEM WILL DROP ACROSS THE CENTRAL AND NORTHERN
PORTIONS OF THE LAKE EARLY THIS EVENING...WITH A COLD FRONT PUSHING
EASTWARD ACROSS THE SOUTHERN PORTION OF THE LAKE EARLY THIS EVENING.
ONCE THIS SYSTEM PASSES OVER THE LAKE...A STRONG PUSH OF
ARCTIC AIR AND STRONG PRESSURE RISES WILL SETUP SOME GALE FORCE
NORTH-NORTHWESTERLY WINDS DOWN THE SOUTHERN END OF THE LAKE.
THEREFORE I UPGRADED THE GALE WATCH TO A WARNING AND MOVED IT UP A
FEW HOURS. I ALSO INCLUDED MY INDIANA NEAR SHORES IN THIS
WARNING...AS IT APPEARS A NARROW CHANNEL OF STRONGER WINDS UP TO 40
KT MAY OCCUR TONIGHT IN ASSOCIATION WITH A LAND-LAKE CONVERGENCE
LAKE EFFECT BAND. THERE MAY ALSO BE A PERIOD OF GALES ALONG MY
ILLINOIS NEAR SHORES...ESPECIALLY WITH THE PASSAGE OF THE COLD FRONT
LATE THIS AFTERNOON INTO TONIGHT. HOWEVER...DUE TO THE OFFSHORE
COMPONENT HERE...I FELT BETTER GOING WITH A 30 KT SMALL CRAFT
ADVISORY AND MENTIONING SOME 35 KT GALE FORCE GUSTS. THESE STRONG
WINDS WILL ABATE DURING THE DAY THURSDAY.

ALTHOUGH A SHORT PERIOD OF SUB GALES WILL LIKELY OCCUR LATER
THURSDAY...IT APPEARS THAT STRONG GALES WILL QUICKLY REDEVELOP OUT
OF THE SOUTHWEST LATE THURSDAY NIGHT INTO FRIDAY. A VERY STRONG
PRESSURE GRADIENT LOOKS TO SET UP ACROSS THE GREAT LAKES REGION
DURING THIS EVENT AS A STRONG TROUGH OF LOW PRESSURE DROPS ACROSS
THE UPPER MIDWEST. OVERALL...IT STILL APPEARS THAT HIGH END
SOUTHWESTERLY GALES OF 45 KT WILL OCCUR ON FRIDAY ON BOTH THE NORTH
AND SOUTH PORTIONS OF THE LAKE. THERE IS THE POSSIBILITY THAT STORM
FORCE WINDS WILL EVEN OCCUR WITH THIS...GIVEN THE STRENGTH OF THE
PRESSURE GRADIENT. I HAVE ADDED A MENTION OF STORM FORCE GUSTS. A
GALE WATCH OR STORM WATCH WILL LIKELY BE NEEDED FOR THIS EVENT.

IF THIS WAS NOT ENOUGH...IT APPEARS ANOTHER VERY STRONG COLD FRONT
WILL DROP ACROSS THE LAKE SOMETIME EARLY SATURDAY. THE WINDS SHOULD
QUICKLY BECOME NORTHWESTERLY GALES UP TO 40 KT IN THE WAKE OF THIS
FRONT.
