RESIDENCE TIME IN OUR CWA IS BECOMING MORE AND MORE LIKELY...AND
THIS SHOULD RESULT IN 10 PLUS INCHES OF SNOW GIVEN CONVECTIVE-LIKE
RATES AT TIMES AND THE WET CLUMPY SNOW ADDING TO THE QUICK
ACCUMULATIONS. THERE IS STILL DIFFERENCES WITH THE FAVORED
CORRIDOR OF BANDED SNOW PLACEMENT BETWEEN GLOBAL AND HIGH-RES
GUIDANCE...WHICH IS NOT SURPRISING GIVEN THE MESOSCALE NATURE OF
BANDS IN A COMPLEX SYSTEM...FROM NORTHWEST INDIANA TO FAR EASTERN
ILLINOIS INTO DOWNTOWN CHICAGO. BUT THE PROXIMITY IN TIME AND
SEEING OBSERVATIONAL TRENDS AND THEIR SUPPORTING HIGH-RESOLUTION
MODELS AND THE NAM/SREF/GFS...WARRANTS BOOSTING FORECAST AMOUNTS.

ALSO FOR THE ENTIRE WINTER STORM WARNING AREA WILL BE WEAVING
INTO FORECAST IMPACTS MESSAGING THE POTENTIAL FOR POWER OUTAGES
DUE TO THE COMBINATION OF A WET SNOW AND HIGH WINDS. ALWAYS A
CHALLENGE WITH THESE WETTER SNOW EVENTS TO GAUGE HOW THAT WILL
DETRACT FROM BLOWING...BUT DO RECALL THAT THE JAN 31-FEB 1 2015
STORM CAUSED POWER OUTAGES DUE TO ITS HEAVY WET NATURE WITH
INCREASING WINDS.

OBSERVATIONAL TRENDS ARE SUPPORTING A MAJORITY OF THE
GUIDANCE...INCLUDING HIGH-RES GUIDANCE...IN A WEST/NORTHWEST
EXPANSION IN THE MODERATE TO HEAVY SNOW AREA ON WEDNESDAY. WATER
VAPOR IMAGERY THIS EVENING SHOWS THE MAIN CLOSED SOUTHERN STREAM
LOW WITH A NEGATIVE TILT ALREADY AND BEGINNING ITS NORTHEAST
MOVEMENT ACROSS THE ARKLATEX. A PERSISTENT STRETCH OF ELEVATED
RADAR ECHOES FROM CENTRAL MISSOURI NORTHEAST TO KANKAKEE IS
HIGHLIGHTING THE ELEVATED TIGHTENING FRONTAL ZONE AND LIKELY
PAINTS THE CORRIDOR ON WHERE SNOW WILL FILL IN QUICKLY LATE
TONIGHT AND MUCH MORE SO WEDNESDAY MORNING. THIS AXIS WILL EXPAND
AND PIVOT NORTHWARD AS THE WELL-DEFINED NORTHERN STREAM WAVE
PHASES WITH THE SYSTEM. THIS MAKES CONCEPTUAL SENSE TO PULL
STRONGER SYNOPTIC LIFT SUPPORTING MESOSCALE BANDING FURTHER
WEST/NORTHWEST...SO FEEL BETTER PUSHING UP SNOW AMOUNTS AND
EXPANDING BACK WEST/NORTHWEST SOME.

WITH THE NORTHEAST FLOW INCREASING EXPECTING TEMPERATURES TO
BASICALLY HOLD STEADY AND THEN TAKE A QUICK DROP AFTER SNOW
STARTS. SOME INITIAL MIX WITH RAIN IS POSSIBLE BUT IT SHOULD BE
BRIEF. RATES WILL OVERCOME THE NOW WARMER PAVEMENT...THE QUESTION
JUST IS HOW QUICKLY. WOULD EXPECT THAT WILL NOT BE MUCH OF A
PROBLEM BY EARLY AFTERNOON BASED ON WHAT WE ARE SEEING.

HAVE UPPED POPS TO BASICALLY 100S IN THE WARNING AREA AND THROUGH
ITS DURATION. HAVE ALSO ADDED BLOWING SNOW WORDING IN NORTHWEST
INDIANA...AND AGAIN MOST CONCERNED IN LAKE AND PORTER WHERE
UNINHIBITED NORTHERLY FLOW WILL BE SEEN INTO THE NORTHERN PARTS OF
THOSE COUNTIES.

UPDATED WSW...FORECAST...AND WEATHER STORY GRAPHIC WILL BE SENT
SHORTLY.

MTF

.SHORT TERM...
111 PM CST

THROUGH TONIGHT...

RAISED HIGH TEMPS DUE TO AMPLE SUNSHINE AND RECENT WARM DAYS. CLOUDS
INCREASE THROUGH THE AFTERNOON AND EVENING.

HIGH PRESSURE OVER THE GREAT LAKES AND NE U.S. SHIFTS NORTHEAST
WHILE THE LOW OVER THE LOWER MISSISSIPPI VALLEY STRENGTHENS.  AS THE
LOW SHIFTS NNE IT MERGES WITH AN UPPER LEVEL TROUGH/VORT STREAMER
CURRENTLY OVER MINNESOTA.  MODELS STILL SHOW SOME DIFFERENCES IN HOW
THE SYSTEM WILL EVOLVE...BUT THINKING PRECIP IN THE FORM OF SNOW AND
RAIN WILL FALL MAINLY SOUTH OF A GARY IN TO PONTIAC IL LINE EARLY
WEDNESDAY MORNING. MODEL SOUNDINGS FEATURE DRY LOW LEVELS SO AS
PRECIP FALLS INTO THAT LAYER...IT COULD HELP THE LAYER TO COOL
RESULTING IN MORE SNOW THAN RAIN. COULD ALSO SEE A BRIEF PERIOD OF
SLEET.  DECIDED TO HAVE SLIGHTLY LOWER SNOWFALL AMOUNTS THROUGH 6AM
WEDNESDAY WITH ONLY A TENTH OR TWO OF SNOW DUE TO LOW CONFIDENCE IN
WHEN SNOW WILL BEGIN TO FALL AND HOW QUICKLY IT WILL ACCUMULATE.
NORTHEAST WINDS ALSO INCREASE OVERNIGHT WITH GUSTS UP TO 40 MPH
ALONG AND EAST OF I-55 EARLY WEDNESDAY MORNING.

JEE

WEDNESDAY THROUGH WEDNESDAY NIGHT...

FOCUS REMAINS ON THE DYNAMIC/WINTER STORM SYSTEM AS IT LIFTS NORTH
EARLY WEDNESDAY. CHALLENGES REMAIN ON HOW QUICKLY THE DYNAMICAL
FORCING WILL BE ABLE TO COOL THE THERMAL COLUMN...BUT THERE HAS BEEN
STEADY CONSISTENCY AMONGST SOLUTIONS.

LARGEST ADJUSTMENT FOR THE AFTERNOON PKG WILL BE THE TRANSITION OVER
FROM A WINTER STORM WATCH TO A WARNING...AND HAVE DELAYED A FEW
HOURS THE START TIME FURTHER NORTH UNTIL 15Z WED. THE OTHER
INCLUSION WAS TO ADD IN COOK/WILL COUNTIES AS THE AXIS OF THE HEAVY
SNOW/HIGHER QPF HAS SHIFTED NORTHWEST. THE OTHER ADJUSTMENT WAS
TO ISSUE A LAKE SHORE FLOOD WARNING FOR LAKE/PORTER INDIANA
COUNTIES...WITH THE WAVE HEIGHTS EXPECTED TO EXCEED 14FT WHICH
WILL LIKELY LEAD TO SOME FLOODING ALONG THE IMMEDIATE NORTHWEST
INDIANA SHORELINE.

GETTING INTO THE METEOROLOGY SIDE OF THE SYSTEM AND CHALLENGES DO
STILL REMAIN WITH RESPECT TO THE TIMING/VOLUME OF SNOW/QPF WITH THE
SYSTEM. GUIDANCE CONTINUES TO FOCUS IN ON PRECIP BEGINNING IN THE
FAR SOUTHERN CWFA AROUND 12Z WED...THEN STEADILY LIFTING
NORTH/NORTHWEST. WITH THE STRONG NORTH TO SLIGHTLY NORTHEASTERLY
WIND COMPONENT THIS MAY HELP TO ERODE THE LEADING EDGE OF
PRECIP/MOISTURE AND DELAY SATURATION...HOWEVER THE DYNAMICAL COOLING
PROCESSES WILL RAPIDLY OVERCOME THE NARROW DRY WEDGE. DEW POINTS
ARE PROGGED TO BE IN THE 30-32 DEGREE RANGE AT THE ONSET...SO THIS
IS EQUALLY A CHALLENGE FOR ACCUMS ONCE WE WET BULB DOWN...AND WILL
RELY ON FORCING AND SOME SUPPRESSION TO DEW POINTS BELOW 32
DEGREES TO OCCUR. THIS WILL ALLOW FOR THE BETTER ACCUMULATIONS TO
TAKE PLACE. THE ENSEMBLES HAVE BEEN STEADILY SHOWING A LARGE AREA
OF HIGHLY ANOMALOUS EASTERLY JET AT NEARLY 55KTS AT 850MB LIFTING
NORTHWEST ACROSS THE SOUTHERN/EASTERN CWFA BY LATE WED
MORNING/EARLY AFTERNOON HOURS. THIS CONTINUES TO BE THE PEAK OF
THE EVENT THROUGH THE EVENING RUSH HOUR FOR THE CHICAGO METRO.

THE AXIS OF HEAVY SNOWFALL DOES APPEAR TO BE PIVOTING WEST BY MIDDAY
AND SHOULD BECOME ORIENTED FROM JUST SOUTH/SOUTHEAST OF DOWNTOWN
CHICAGO TO PONTIAC...THEN BECOME MORE NORTH/SOUTH ORIENTED BY LATE
AFTN EARLY EVE WED. SNOW TO LIQUID RATIO AT THE ONSET...DUE TO THE
HIGHER DEW POINTS AND WARMER SFC TEMPS...WILL LIKELY BE ON THE ORDER
OF 8:1 TO PERHAPS 10:1...THEN AS DYNAMICAL COOLING CONTINUES IN THE
AFTERN HOURS THOSE RATIOS WILL STEADILY INCREASE TO 12:1 TO 15:1 BY
LATE AFTN/EVE. GUSTY WINDS WILL COMBINE WITH THE FALLING SNOW AND
CREATE PERIODS OF HEAVY SNOW ALONG WITH NEAR WHITE-OUT CONDITIONS.
VISIBILITIES WILL LIKELY FLUCTUATE BETWEEN ONE HALF MILE TO AT TIMES
LESS THAN ONE QUARTER...MAINLY FOR THE OPEN RURAL LOCATIONS THIS
WILL POSE A HAZARD. WHICH WOULD MAKE IT FEEL LIKE NEAR BLIZZARD
CONDITIONS. SNOWFALL TOTALS WILL BE HEAVIEST ALONG AND EAST OF A
FORD TO JUST SOUTHEAST OF CHICAGO...WITH TOTALS BETWEEN 5 TO 9
INCHES. MEANWHILE WEST OF THIS LINE SNOW TOTALS QUICKLY DROP...AND
AREAS ALONG AND WEST OF A MENDOTA TO CRYSTAL LAKE MAY ONLY SEE A
DUSTING AT BEST. THE CAVEAT CONTINUES TO BE THAT IF THE AXIS OF
STRONGEST FGEN SHIFTS WEST THIS WILL PUSH SNOWFALL TOTALS HIGHER TO
THE WEST.

THE STRONGER VORT WILL BE LIFTING NORTHEAST INTO SOUTHERN MICHIGAN
BY 21Z WED...WHICH SHOULD BRING THE PERIODS OF HEAVY SNOWFALL TO AN
END FROM WEST TO EAST...WITH SOME LINGERING PRECIP THROUGH THE LATE
EVENING HOURS EAST OF I-39.

AS THE LOW AND DEEPER MOISTURE PEELS NORTHEAST...WINDS WILL BE
TURNING NORTHWESTERLY AND PRESSURE RISES WILL BEGIN TO DIMINISH
ALLOWING GUSTS TO DIMINISH. THE STEADIER SNOW WILL TRANSITION
TOWARDS FLURRIES BY LATE EVENING WED...WITH OVERNIGHT LOWS IN THE
UPR 20S EXPECTED.

&&

.LONG TERM...
324 AM CST

ATTENTION TODAY WAS FOCUSED ON THE SHORT TERM DUE TO THE HIGH
IMPACT WINTER STORM.

&&

.AVIATION...
FOR THE 06Z TAFS...

1058 AM...A MAJOR WINTER STORM WILL AFFECT THE CHICAGO AREA
TERMINALS FROM LATE WEDNESDAY MORNING THROUGH AT LEAST LATE
WEDNESDAY EVENING...POSSIBLY THURSDAY MORNING.

NO SIGNIFICANT CHANGES TO OVERALL FORECAST THINKING FROM THE 00Z
TAFS. LOW PRESSURE OVER WESTERN TN LATE THIS EVENING WILL MOVE TO
NORTHWEST OH BY WEDNESDAY EVENING. SNOW IS EXPECTED TO DEVELOP
ACROSS THE CHICAGO AREA TERMINALS DURING THE MID/LATE MORNING ON
WEDNESDAY AND CONTINUE THROUGH THE AFTERNOON AND INTO WEDNEDSAY
NIGHT...AS THE INTENSITY SLOWLY WEAKENS.

THE 00Z MODEL GUIDANCE HAS CONTINUED WITH THE PREVIOUS WESTERN
SHIFT TO THE TRACK OF THE LOW AND ARE ALSO IN GOOD AGREEMENT. SO
FORECAST CONFIDENCE IN THE OVERALL TRENDS CONTINUES TO INCREASE.
EXPECT SEVERAL HOURS OF PREVAILING 1/2SM WITH PERIODS OF 1/4SM AT
MDW/GYY AND FOR NOW...ONLY INCLUDED THESE CONDITIONS IN A TEMPO
THOUGH ITS QUITE POSSIBLE THERE COULD BE AT LEAST A FEW HOURS OF
PREVAILING 1/4SM AND HEAVY SNOW AT GYY AND POSSIBLY MDW.

SNOW INTENSITY CURRENTLY LOOKS JUST A BIT LIGHTER AT DPA THOUGH
ITS POSSIBLE VIS MAY DROP UNDER 1SM FOR A TIME IN THE AFTERNOON.
STILL EXPECT A SHARP GRADIENT ON THE WESTERN EDGE OF THE SNOW BUT
ITS POSSIBLE LIGHT SNOW MAY DEVELOP AT RFD IN THE AFTERNOON.
CONFIDENCE TOO LOW TO INCLUDE ANY MENTION WITH THIS FORECAST.

NORTH/NORTHEAST WINDS HAVE ALREADY INCREASED INTO THE 10-15KT
RANGE AND APPEARS SPEEDS/GUSTS WILL INCREASE FASTER THAN PREVIOUS
FORECAST AND ADJUSTED ACCORDINGLY. GUSTS INTO THE 35-40KT RANGE
STILL ON TRACK FOR MUCH OF THE AFTERNOON WITH SOME POTENTIAL FOR
OCCASIONALLY HIGHER GUSTS. WIND DIRECTION WILL SLOWLY TURN MORE
TO THE NORTH DURING THE AFTERNOON AND THEN TO THE NORTH/NORTHWEST
WEDNESDAY EVENING. CMS

&&

.MARINE...
213 PM CST

A SIGNIFICANT LOW PRESSURE SYSTEM IS PROGGED TO IMPACT LAKE
MICHIGAN WITH WINDS RAMPING UP TO GALE FORCE LATE TONIGHT AND
APPROACHING STORM FORCE AT TIMES WEDNESDAY EVENING AND NIGHT AS
DEEP AREA OF LOW PRESSURE LIFTS ACROSS THE OHIO VALLEY. STRONG
NORTHERLY GALES WILL DRIVE WAVES INTO THE 15 TO 20 FT RANGE ACROSS
THE SOUTHERN PORTIONS OF LAKE MICHIGAN. EXPECT WINDS TO FINALLY
DROP BACK BELOW GALE FORCE THURSDAY EVENING OR OVERNIGHT. HIGH
PRESSURE BUILDS OVER THE REGION BRIEFLY ON FRIDAY...THEN LOW
PRESSURE DROPS ACROSS ONTARIO SATURDAY FOLLOWED BY ANOTHER LOW
OVER THE MIDWEST SUNDAY.
