Heavy Snow in Illinois, February 24 to 25, 2016

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
909 AM CST WED FEB 24 2016

.UPDATE...
908 AM CST

BAND OF HEAVY SNOW HAS MOVED INTO SOUTHERN COOK COUNTY THIS MORNING
AND STRETCHES SOUTHWEST TO NEAR PONTIAC WHERE VISIBILITY HAS DROPPED
ANYWHERE FROM 3/4 OF A MILE TO LESS THAN A QUARTER MILE. PIVOT POINT
OF THE DEFORMATION ZONE CAN BE SEEN NEAR LINCOLN IL AND HAVE NOTICED
SOME MODEST WEAKENING ALONG THE LEADING EDGE OF THE F-GEN SNOW BAND
AS IT SWINGS NORTHWEST ACROSS THE CHICAGO METRO AREA AND ENCOUNTERS
DRIER LOW/MID LEVEL AIR. MID LEVEL F-GEN PROGGED TO REMAIN STRONG
OVER NEXT FEW HOURS THOUGH SO SHOULD BE ABLE TO OVERCOME THE DRY
AIR AND SEE A LITTLE MORE ADVANCEMENT OF THE SNOW ACROSS THE METRO.
INCREASED SNOW TOTALS SLIGHTLY WHERE THE AXIS OF HEAVIEST SNOW IS
CURRENTLY FALLING BUT OTHERWISE NO SIGNIFICANT CHANGES AND IT
STILL APPEARS A LARGE GRADIENT IN SNOWFALL WILL OCCUR NW-SE
ACROSS THE CHICAGO METRO.

&&

.SHORT TERM...
345 AM CST

THROUGH THURSDAY...

APOLOGIZE FOR RUNNING A LITTLE LATE THIS MORNING...VERY BUSY
SHIFT AS YOU CAN IMAGINE.

OVERALL THINKING FROM PREVIOUS FORECASTS LARGELY UNCHANGED. HAVE
OPTED TO UPGRADE PORTIONS OF EAST CENTRAL ILLINOIS INTO NORTHWEST
INDIANA TO A BLIZZARD WARNING...AS CONFIDENCE HAS GROWN REGARDING
THE LONGEST DURATION PLACEMENT OF THE MOST INTENSE SNOW BAND.
STILL APPEARS THERE WILL BE A VERY SHARP CUT OFF TO THE SNOW ON
THE WESTERN FLANKS...WITH POTENTIALLY UP TO A 10 INCH OR MORE
GRADIENT FROM FAR SE COOK TO FAR NW COOK COUNTY.

STILL ANTICIPATE CHARACTER OF THE SNOW TO BE HEAVY...WET...AND
NOT PARTICULARLY BLOWABLE...HOWEVER THE FALLING SNOW ALONE IN THE
HEAVIEST BAND(S) SHOULD HAVE NO PROBLEM KNOCKING VISIBILITIES TO
ONE QUARTER MILE. WINDS WILL INCREASE TO 25 TO 35 MPH WITH
FREQUENT GUST TO 45 MPH WHICH SHOULD RESULT IN WIND WHIPPED SNOW
CAUSING WHITE OUT CONDITIONS. WINDS WILL BE EVEN STRONGER NEAR
LAKE MICHIGAN WHERE GUSTS OF 50 TO 60 MPH ARE POSSIBLE. JUST TO
THE NORTHWEST OF THE BLIZZARD WARNING...PERIODIC WHITE AND
BLIZZARD CONDITIONS ARE POSSIBLE...THOUGH CONFIDENCE IS NOT AS
HIGH AND SNOWFALL GRADIENT SHOULD BE LARGER...SO OPTED TO MAKE NO
CHANGES TO REMAINDER OF THE INHERITED HEADLINES. CONDITIONS WILL
IMPROVE FROM WEST TO EAST THIS EVENING...THOUGH SOME LAKE
ENHANCEMENT TO THE SNOW COULD KEEP INTENSITY UP INTO THE NIGHT
OVER NORTHWEST INDIANA.

GIVEN THE LIKELIHOOD OF MESOSCALE BANDING...IT IS QUITE POSSIBLE
SNOWFALL TOTALS WILL NEED TO BE TWEAKED SOME DURING THE EVENT.
HOWEVER...FAIRLY GOOD AGREEMENT IN THE AVAILABLE SUITE OF HIRES
MESOSCALE MODELS HAS ADDED SOME DEGREE OF CONFIDENCE TO THE
FORECAST STORM TOTAL SNOWFALL MAP. GENERALLY LOOKING FOR A SWATH
OF 6 TO 14 INCHES OF SNOW FROM FORD/IROQUOIS COUNTIES NORTHEAST
ACROSS NORTHWEST INDIANA. MULTIPLE MODELS SUGGEST THE PIVOT POINT
FOR THE DEFORMATION BAND WILL BE OVER EXTREME NORTHWEST
INDIANA...WHICH WHEN COMBINED WITH SOME POSSIBLE MINOR LAKE
ENHANCEMENT COULD RESULT IN MAX SNOWFALL TOTALS APPROACHING A FOOT
AND A HALF IN SOME ISOLATED LOCATIONS BY LATE TONIGHT.

.LONG TERM...
409 AM CST

THURSDAY NIGHT THROUGH TUESDAY...

FOR THE LONGER TERM FORECAST PERIOD...THE MAIN CONCERN WILL BE
LINGERING IMPACTS FROM THE LATE SEASON WINTER STORM.

BY THURSDAY EVENING...THE MAIN SFC LOW WILL MOVE MOVE THROUGH
SOUTHERN QUEBEC WHILE HIGH PRESSURE BUILDS ACROSS THE NORTHERN AND
CENTRAL PLAINS.  A RELATIVELY STRONG NORTHERLY PRESSURE GRADIENT
WILL PERSIST ACROSS THE REGION ALONG WITH STRONG PRESSURE RISES AS
THE LOW PULLS OFF TO THE NORTHEAST AND HIGH PRESSURE BUILDS IN FROM
THE WEST.  STRONG...GUSTY NORTH WINDS WILL PERSIST THROUGH THE NIGHT
WITH GUSTS UP TO 30 MPH.  WINDS SHOULD BEGIN TO BACK TO NWLY AND
DIMINISH TO 10 TO 15 MPH BY AROUND DAYBREAK FRIDAY MORNING.
RELATIVELY QUIET CONDITIONS WILL PREVAIL FOR FRIDAY AND THROUGH THE
WEEKEND.  A RAPID WARMING TREND WILL COMMENCE ON FRIDAY WITH HIGHS
REBOUNDING BACK INTO THE LOWER TO MIDDLE 30S.  BY SATURDAY...HIGHS
IN THE UPPER 40S TO AROUND 50 ARE EXPECTED AND BY SUNDAY...STRONG
WARM ADVECTION BETWEEN HIGH PRESSURE PARKED OVER THE NRN GULF COAST
AND LOW PRESSURE TRACKING ACROSS THE NRN PLAINS.  HIGHS ON SUNDAY
ARE EXPECTED TO BE IN THE LOWER TO MIDDLE 50S.

THE NEXT CHANCE FOR PCPN WILL NOT BE UNTIL BE UNTIL SUNDAY AFTERNOON
AND EVENING IN AN ZONE OF BROAD WEAK WARM ADVECTION IN ADVANCE TO
THE SFC LOW AS IT PASSES THROUGH SRN WISCONSIN.  GIVEN THE
UNSEASONABLY HIGH TEMPERATURES THROUGH THE DAY AND INTO THE
EVENING...ANY PCPN SHOULD BE ALL LIQUID...THOUGH IT COULD TAPER OFF
AS A RAIN/SNOW MIX OR SOME LIGHT SNOW BY MONDAY MORNING.  LITTLE OR
NO SNOW ACCUMULATION IS LIKELY WITH THIS SYSTEM.  TEMPERATURES
SHOULD REMAIN WELL ABOVE NORMAL INTO EARLY NEXT WEEK AS SFC HIGH
PRESSURE BUILDS IN BEHIND THE EXITING LOW WHILE WEAK RIDGING ALSO
BUILDS ALOFT.

.AVIATION...
14/15Z UPDATE...
NO REAL BIG CHANGES TO CURRENT TAFS WITH LATEST RADAR IMAGERY
DEPICTING LIGHT SNOW CURRENTLY MOVING TOWARDS THE MDW/ORD/DPA
TERMINALS...WITH A MORE INTENSE BAND SITUATED RIGHT OVER THE GYY
AIRPORT. OVERALL TRENDS HAVE BEEN FOR THIS HEAVIER SNOW TO SLOWLY
WORK NORTHWEST...AND THINK THIS MODERATE/HEAVIER SNOW HAS A CHANCE
TO WORK ACROSS THE MDW AND ORD/DPA TERMINALS BY MID TO LATE
MORNING. SO HAVE MAINTAINED LOWEST SNOW/VIS TRENDS IN THE
TAFS TODAY...AND LOWER CEILINGS BY MIDDAY. DID ADJUST WIND
DIRECTION THROUGH THE AFTERNOON...AS A PREVAILING NORTHEAST
DIRECTION WILL LIKELY BE IN PLACE FOR MOST OF TODAY BEFORE
TURNING MORE NORTHWEST THIS EVENING.

FOR THE 12Z TAFS...

A MAJOR WINTER STORM WILL AFFECT THE CHICAGO AREA TERMINALS
THROUGH LATE TONIGHT OR EARLY TOMORROW MORNING.

MADE SOME ADJUSTMENTS TO THE GOING FORECAST WITH THE 09Z UPDATE TO
LINE UP WITH THE LATEST THINKING AT THAT TIME WHICH WAS SUGGESTING
THAT THE WORST CIG/VIS CONDITIONS ASSOCIATED WITH HEAVY SNOW WAS
LIKELY AT THE CHICAGO AREA TERMINALS DURING THE LATE AFTERNOON
HOURS. AT THAT TIME...A PERIOD OF 1/4SM VIS AND LIFR CIGS WERE
LIKELY WITH THE HEAVIEST BAND OF SNOW. STILL THINK THAT THIS IS A
VALID FORECAST WITH THE HEAVIEST BAND OF SNOW...BUT THE LATEST
HIGH RES AND LARGER SCALE MODEL RUNS ARE ONCE AGAIN FLIP-FLOPPING
ON THE NWRN EDGE OF THE SNOW...INDICATING THE POSSIBILITY THAT THE
NWRN EDGE OF THE HEAVIER SNOW COULD BE TO THE SOUTH AND EAST OF
ORD/MDW/DPA AND THAT THERE IS INCREASING BUST POTENTIAL FOR THE
SNOW AND ASSOCIATED CIGS/VIS. WHILE CONFIDENCE IS NOT YET HIGH
ENOUGH TO MAKE WHOLESALE CHANGES TO THE FORECAST...HAVE BACKED OFF
ON THE +SN AT ORD...BUT WILL MAINTAIN +SN AT MDW FOR NOW IN
DEFERENCE TO THE IDEA THAT THERE WILL BE A SHARP GRADIENT TO THE
NORTHWESTERN EDGE OF THE SNOW...THE CONCERN REMAINS EXACTLY WHERE
THAT LINE WILL BE DRAWN. SHOULD LATER GUIDANCE AND OBSERVATIONAL
TRENDS CONTINUE TO BACK OFF ON THE SNOW POTENTIAL FOR ORD/MDW...
FURTHER CHANGES WILL BE NEEDED. BUT...IN GENERAL...CONFIDENCE IS
DECREASING ON THE THE SNOW POTENTIAL.

WHILE THE CONFIDENCE IN THE SNOW FORECAST IS WANING...CONFIDENCE
REMAINS HIGH IN THE WIND FORECAST. NORTHEAST WINDS HAVE ALREADY
INCREASED BEEN GUSTING IN EXCESS OF 30 KT MORNING AND WILL
CONTINUE TO RAMP UP THROUGH THE MORNING. GUSTS IN THE 35-45KT
RANGE ARE ON TRACK FOR MUCH OF THE AFTERNOON WITH SOME POTENTIAL
FOR OCCASIONALLY HIGHER GUSTS...PARTICULARLY FOR MDW AND GYY. GYY
COULD SEE A FEW GUSTS IN EXCESS OF 50 KT LATE THIS AFTERNOON OR
EARLY THIS EVENING. WIND DIRECTION WILL SLOWLY TURN MORE TO THE
NORTH DURING THE AFTERNOON AND THEN TO THE NORTH/NORTHWEST
WEDNESDAY EVENING. WINDS SHOULD BEGIN TO DIMINISH TONIGHT...BUT
WILL REMAIN GUSTY TO 25-30 KT THROUGH THE NIGHT.

.MARINE...
409 AM CST

A DEEPENING LOW PRESSURE SYSTEM TRACKING THROUGH THE LOWER OHIO
VALLEY EARLY THIS MORNING WILL CONTINUE TO DEEPEN AS IT REACHES THE
EASTERN GREAT LAKES BY LATE THIS AFTERNOON.  THE LATEST EXPECTED
STORM TRACK IS A LITTLE WEST OF THE PREVIOUS FORECASTS AND AN EVEN
STRONGER NORTHERLY PRESSURE GRADIENT IS EXPECTED TO DEVELOP OVER
LAKE MICHIGAN. WHEN COMBINED WITH STRONG PRESSURE FALLS IN ADVANCE
OF THE LOW LATER THIS MORNING AND THEN STRONG PRESSURE RISES LATER
THIS EVENING AS THE LOW LIFTS OFF TO THE NORTHEAST...EXPECT A PERIOD
OF STORM FORCE WINDS...MAINLY FOR THE SOUTHERN PORTIONS OF THE LAKE
AND THE NEARSHORE WATERS OF ILLINOIS AND INDIANA...WHERE THE
GRADIENT WILL BE STRONGEST.  THE SOUTHERN OPEN WATERS AND THE
INDIANA NEARSHORE WATERS COULD SEE STORM FORCE WINDS AS HIGH AS 55
KT WHILE THE ILLINOIS NEARSHORE WATERS WILL LIKELY BE SLIGHTLY
LOWER...AT 50 KT.  THE EXTENDED PERIOD OF VERY STRONG NORTH WINDS
WILL DRIVE WAVES UP TO 20 TO 25 FT OVER THE SOUTH END OF THE LAKE.
STORM FORCE WINDS SHOULD DIMINISH BY LATE TONIGHT...AND A PERIOD OF
GALES OF 35-45 KT SHOULD THEN PERSIST OVER THE SRN PORTIONS OF THE
LAKE INTO THURSDAY EARLY THURSDAY EVENING AND LATE THURSDAY NIGHT
FOR THE NORTHERN PORTIONS OF THE LAKE.  WINDS AND WAVES SHOULD
DIMINISH CONSIDERABLE FRIDAY AND FRIDAY NIGHT AS HIGH PRESSURE BUILDS
ACROSS THE LAKE.  AS THE HIGH MOVES OFF TO THE EAST AND LOW PRESSURE
DROPS INTO THE NORTHERN PLAINS...A STRENGTHENING SWLY GRADIENT WILL
SET UP WITH WINDS RISING BACK TO ARND 30 KT FOR FRIDAY NIGHT AND
SATURDAY.  WHILE ANOTHER ROUND OF GALES IS NOT EXPECTED...A SMALL
CRAFT ADVISORY WILL LIKELY BE NEEDED FOR THE BRISK SWLY WINDS FOR
THE NEARSHORE WATERS.
