What happened
The episode as NWS LOT wrote it up.
From December 31st to January 1st, a snow storm brought 2 to 6 inches of snow to the Chicago metro area. Immediately behind this system, scattered lake effect snow showers began to impact portions of northeastern Illinois. By late morning and early afternoon, the multi-banded lake effect snow showers began to evolve towards a single band, which gradually shifted south and east across the Chicago metro into northwest Indiana. Up to around an additional foot of snow fell in some areas. The highest snowfall reports (combining the system snow with the lake effect snow) include: 18.8 inches near Gurnee; 18.2 inches in Mundelein; 16.1 inches near Elk Grove Village; 14.9 inches near Iverness; 13.1 inches near Elmhurst; 10.8 inches in Oak Brook; 9.7 inches at the National Weather Service office in Romeoville; and 9.3 inches in Lockport.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
1216 AM CST THU JAN 2 2014
.DISCUSSION...
314 PM CST
TONIGHT THROUGH THURSDAY NIGHT...
THE MAIN CONCERNS ARE WITH THE TRANSITION OF THE SYNOPTIC/LAKE
ENHANCED SNOW TO A HEAVY LAKE EFFECT SNOW EVENT LATER TONIGHT INTO
THURSDAY ACROSS PORTIONS OF NORTHEASTERN ILLINOIS AND INTO
NORTHWESTERN INDIANA. THIS IS A COMPLEX FORECAST...ESPECIALLY IN
TERMS OF HEADLINES...GIVEN THE ONGOING SNOW ACROSS THE AREA.
TO KEEP THINGS SIMPLE AND SOMEWHAT LESS COMPLEX...WE HAVE DECIDED TO
GO OUT THE DOOR WITH A LAKE EFFECT SNOW WARNING FOR COOK AND LAKE
ILLINOIS...IN SPITE OF THE FACT THAT THE MAIN LAKE EFFECT SNOWS WILL
NOT GET GOING UNTIL TONIGHT AND ON THURSDAY. WE ALSO WENT WITH A
LAKE EFFECT SNOW WARNING FOR LAKE COUNTY INDIANA...BUT WE WILL NOT
START IT HERE UNTIL THURSDAY. THE REMAINDER OF THE WINTER WEATHER
ADVISORY REMAINS IN EFFECT...AND I HAVE EXTENDED IT THROUGH THIS
EVENING FOR MUCH OF NORTHEASTERN ILLINOIS (COUNTIES NOT INCLUDED IN
THE LAKE EFFECT SNOW WARNING)....AND THROUGH EARLY THURSDAY
MORNING...MAINLY FOR AREAS ALONG AND SOUTH OF INTERSTATE 80.
A LAKE EFFECT SNOW ADVISORY MAY BE NEEDED FOR BEYOND THE ENDING OF
THE CURRENT WINTER WEATHER ADVISORY FOR AREAS INLAND TO THE SOUTH OF
THE CURRENT WARNING. HOWEVER...I WILL ALLOW LATER SHIFTS TO BETTER
ASSESS THIS POTENTIAL GIVEN THE CURRENT HEADLINES IN EFFECT.
THE MAIN SYNOPTIC SCALE SNOW BAND WILL BEGIN TO SHIFT SOUTHWARD THIS
EVENING AS A POTENT SHORT WAVE DIGS OVER THE OZARKS. THIS SHOULD
FAVOR THE BETTER FRONTOGENESIS AND SNOW POTENTIAL SHIFTING
SOUTHWARD A BIT ACROSS AREAS ROUGHLY ALONG AND SOUTH OF INTERSTATE
80...WHERE LITTLE SNOW HAS FALLEN YET. THE SNOW SHOULD CONTINUE
THROUGH MUCH OF THE NIGHT...ESPECIALLY ACROSS MY EAST CENTRAL
ILLINOIS AND NORTHWESTERN INDIANA COUNTIES...WHERE A GOOD BAND A
MID LEVEL FGEN WILL CONTINUE TO RESIDE AS THE 850 MB CIRCULATION
CONTINUES TO STRENGTHEN IN RESPONSE TO THE MID LEVEL DISTURBANCE
PUSHING ACROSS THE OZARKS. THE SNOW COULD BE MODERATE AT
TIMES...AND THIS COULD LEAD TO 2 TO 4 INCHES OF ACCUMULATION YET
FOR THE SOUTHERN HALF OF MY AREA THAT HAS YET TO SEE ANY REAL
SNOWFALL FROM THIS SYSTEM.
FARTHER NORTH...ALTHOUGH THE SYNOPTIC SCALE SNOW WILL BE WINDING
DOWN...LAKE EFFECT SNOW SHOWERS SHOULD BEGIN TO ORGANIZE ACROSS
WESTERN LAKE MICHIGAN TONIGHT. MUCH OF THE HIGH RES GUIDANCE ALSO
INDICATES THAT A BAND OF LAKE EFFECT SNOW SHOWERS WILL DEVELOP AS
EARLY AS THIS EVENING ACROSS PORTIONS OF NORTHEASTERN ILLINOIS. THIS
APPEARS TO BE THE RESULT OF AN ENHANCED BAND OF BOUNDARY LAYER
MOISTURE CONVERGENCE IN ASSOCIATION WITH THE DEVELOPMENT OF A MESO
LOW ACROSS FAR SOUTHERN LAKE MICHIGAN THIS EVENING. CONSIDERING THIS
IS THE REGION WHERE A SYNOPTIC SCALE SURFACE INVERTED TROUGH OF LOW
PRESSURE CURRENTLY RESIDES...IT SEEMS QUITE PLAUSIBLE THAT AS THE
THERMODYNAMICS CONTINUE TO GET MORE FAVORABLE ACROSS SOUTHERN LAKE
MICHIGAN...THAT A LOCALIZED ENHANCEMENT/DEVELOPMENT OF A MESO LOW
COULD OCCUR. THIS COULD RESULT IN SOME SNOW ACCUMULATIONS ACROSS
PORTIONS OF COOK...LAKE, IL AND PERHAPS INLAND ACROSS PORTIONS OF
DUPAGE AND KANE COUNTIES. FOR THESE REASONS...I HAVE EXTENDED THE
WINTER WEATHER ADVISORY THROUGH THIS EVENING FOR AREAS JUST WEST OF
THE LAKE EFFECT SNOW WARNING.
ON THURSDAY...THE MAIN LAKE EFFECT BAND IS FORECAST TO SET UP ACROSS
SOUTHWESTERN LAKE MICHIGAN... AND THIS BAND WILL LIKELY MOVE INLAND
ACROSS EASTERN AND SOUTHERN COOK COUNTY...AND FAR EASTERN LAKE
COUNTY ILLINOIS DURING THE MORNING. GIVEN THE STRONG SINGLE BAND
BOUNDARY LAYER CONVERGENCE EXPECTED ACROSS SOUTHWESTERN LAKE
MICHIGAN IN CONJUNCTION WITH VERY IMPRESSIVE THERMODYNAMICS
FEATURING LAKE INDUCED EL'S UP AROUND 10,000 FEET AGL AND 850 TO
SURFACE LAKE TEMP DIFFERENCES AROUND 20 DEGREES CELSIUS...I EXPECT A
BAND OF HEAVY LAKE EFFECT SNOW TO IMPACT PORTIONS OF THE WARNING
AREA ON THURSDAY. MUCH OF THE HIGH RES GUIDANCE REALLY HITS EAST
CENTRAL AND SOUTHERN COOK COUNTY...AND PORTIONS OF FAR NORTHWESTERN
LAKE COUNTY INDIANA REALLY HARD...WITH THE POTENTIAL FOR ISOLATED
AMOUNTS IN EXCESS OF 8 TO 10 INCHES. LAKE COUNTY ILLINOIS REMAINS
SOMEWHAT IN QUESTION AS TO HOW MUCH SNOW WILL FALL...WITH THE BEST
POTENTIAL OF HEAVY SNOWFALL NEAR THE LAKE MICHIGAN SHORES. AREAS
FARTHER INLAND ACROSS THE COUNTY MAY NOT GET MUCH ADDITIONAL
ACCUMULATIONS DURING THE DAY ON THURSDAY. BUT ANY SLIGHT DEVIATION
OR RIPPLE IN THE SNOW BAND...COULD EASILY PUSH SOME HEAVY SNOW
INLAND.
THE LAKE EFFECT BAND COULD EASILY DROP 2+ INCH PER HOUR SNOW AMOUNTS
ACROSS ISOLATED AREAS OF WARNING. THIS BAND OF HEAVY SNOW LOOKS TO
SHIFT EASTWARD ACROSS NORTHWESTERN INDIANA BY THURSDAY EVENING...AND
DEPENDING ON HOW FAST THIS TRANSITIONS OCCURS...THERE COULD BE SOME
DECENT ACCUMULATIONS INTO PORTER COUNTY INDIANA THURSDAY NIGHT. THIS
COULD BE ENOUGH TO WARRANT AN EXTENSION OF THE CURRENT WARNING...OR
AN ADVISORY...BUT DUE TO THE LATER TIMING AND QUESTIONS ON THE
DURATION ACROSS PORTER...I HAVE CHOSEN TO HOLD OFF ON ANY HEADLINES
THERE AT THIS TIME.
KB
FRIDAY...
NORTHWEST FLOW ALOFT TURNS INTO WEAK RIDGING WHILE A SURFACE HIGH
MOVES OVER THE REGION FRIDAY. THE HIGH QUICKLY SHIFTS EAST DURING
THE DAY WITH WINDS BECOMING SOUTH AND STRENGTHENING ON ITS BACKSIDE.
925MB TEMPS RISE TO AROUND -10C BY THE LATE AFTN...BUT GIVEN THE
VERY COLD START...KEPT HIGH TEMPS IN THE TEENS. NO PRECIP IS
EXPECTED...BUT CLOUD COVER INCREASES OVERNIGHT AHEAD OF THE NEXT
SYSTEM. WINDS WILL REMAIN STRONG OVERNIGHT WITH WAA IN FULL SWING.
925 MB TEMPS RISE TO -6 TO -8C BY MIDNIGHT FRIDAY NIGHT...SO
THINKING TEMPS WILL NOT COOL TOO MUCH OVERNIGHT. KEPT LOWS AROUND
+10 TO THE MID TEENS. HOWEVER...THE STRONG WINDS AROUND MPH GUSTING
TO 30 KT WILL MAKE WIND CHILLS BE IN BETWEEN 0 AND -10F.
SATURDAY AND SUNDAY...
THE NEXT LOW PASSES OVER SOUTHERN ONTARIO SATURDAY MORNING WITH ITS
COLD FRONT SWINGING THROUGH SATURDAY AFTN/EVENING. THE GFS REMAINS
A BIT QUICKER WITH THE SYSTEM AND COLD FRONT. FIRST...TEMPS
CONTINUE TO RISE ON SATURDAY WITH HIGHS AROUND 30 DEGREES...AND
SADLY THIS WILL BE BALMY GIVEN THE REST OF THE FORECAST. SNOW IS
EXPECTED ALONG THE COLD FRONT AS IS COLD AIR. TEMPERATURES TUMBLE
BEHIND THE COLD FRONT WITH TEMPS IN THE SINGLE DIGITS ACROSS NORTH
CENTRAL IL AND THEN UPPER TEENS TO NEAR 20 DEGREES ACROSS NORTHWEST
INDIANA.
GUIDANCE CONTINUES TO INDICATE A SECONDARY SURFACE LOW WILL FORM
ALONG THE COLD FRONT OVER THE GULF COAST SUNDAY MORNING. THE LOW
PUSHES UP THE OHIO RIVER VALLEY OR APPALACHIANS DEPENDING ON WHAT
MODEL YOU LOOK AT. THE ECMWF HAS THE LOW FURTHER WEST AND IT
PROLONGS SNOW OVER THE CWA THROUGH SUNDAY NIGHT. THE GFS AND ITS
MORE EASTERLY TRACK KEEPS THE LINGERING SNOW JUST EAST OF OUR CWA.
GIVEN THE DIFFERENCES KEPT A CHANCE OF PRECIP ACROSS THE CWA SUNDAY
AND THEN HAVE THE PRECIP SHIFTING EAST SUNDAY NIGHT.
FOR TEMPS THINKING MAX TEMPS WILL BE REACHED EARLY SUNDAY MORNING AS
TEMPS CONTINUE TO FALL. GUIDANCE HAS 925MB TEMPS AT -10C TO -20C BY
LATE AFTN..WHICH IS NOTHING COMPARED TO THE -25C TO -30C EXPECTED BY
DAWN ON MONDAY. LOWS WILL BE BELOW ZERO FOR ALL LOCATIONS...EXPECT
AREAS ALONG THE LAKE IN NW INDIANA. NORTHWEST FLOW SHOULD KEEP
THOSE LOCATIONS RIGHT AROUND 0. WITH FRESH SNOW ON THE
GROUND...COULD EASILY SEE TEMPS BEING LOWER...BUT GIVEN CLOUD SKIES
AND WINDS 10+MPH...THINKING THERE WILL BE ENOUGH MIXING TO REMAIN ON
THE CONSERVATIVE SIDE. MIN WIND CHILLS LESS THAN -20F ARE EXPECTED.
EXTENDED...MONDAY AND TUESDAY
COLD CONTINUES THROUGH EARLY NEXT WEEK AS THE UPPER LEVEL TROUGH
SLOWLY ROTATES THROUGH. THE COLDEST AIR ALOFT IS EXPECTED MONDAY
INTO MONDAY NIGHT WITH 925MB TEMPS BELOW -30C. HIGHS MONDAY WILL
LIKELY REMAIN BELOW ZERO...EXCEPT ONCE AGAIN FOR AREAS NEAR THE LAKE
ACROSS NW INDIANA. WIND CHILLS OF -20F TO MAYBE -35F ARE CURRENTLY
FORECAST. ONCE AGAIN...AMBIENT TEMPS MAY BE EVEN COOLER THAN
FORECAST.
IF YOU THINK THATS COLD YOU SHOULD SEE MONDAY NIGHT. MOISTURE
SHIFTS EAST AND THINKING CLOUDS WILL BEGIN TO THIN AFTER MIDNIGHT
FROM WEST TO EAST. THIS ONCE AGAIN COULD CERTAINLY LEAD TO MUCH
COLDER AMBIENT TEMPS. RIGHT NOW HAVE -10 TO -20F FORECAST WITH WIND
CHILLS AROUND -40F. A LITTLE RELIEF IS EXPECTED TUESDAY BUT TEMPS
WILL STILL BE BELOW 0. WINDS WILL BE DIMINISHING AS HIGH PRESSURE
SPREADS OVERHEAD. TUESDAY NIGHT WILL ONCE AGAIN BE BITTERLY COLD
WITH -10 TO -20F AND WIND CHILLS AROUND -30F.
THE EXTENDED IS MAINLY DRY WITH CONTINUING CHANCES FOR LAKE EFFECT
SNOW MAINLY OVER NW INDIANA. KEPT SLIGHT CHANCE TO CHANCE POPS
GOING AS NORTHWEST TO WEST WINDS PROVIDE ENOUGH OF A FETCH GIVEN THE
BITTERLY COLD AIR TO PRODUCE A LITTLE SNOW. RIGHT NOW
THOUGH...THINKING THE BETTER SNOW WILL FALL EAST OF THE CWA. WINDS
TURN SOUTHWEST SHUTTING OFF LAKE EFFECT SNOW.

.AVIATION...
//ORD AND MDW CONCERNS...UPDATED 06Z...
* LIGHT SNOW AND BLOWING SNOW OVERNIGHT.
* HEAVIER LAKE EFFECT SNOW SHOWERS TOWARD MORNING WITH IFR/LIFR
POSSIBLE.
* NORTHEAST WINDS BECOMING NORTH-NORTHEAST BY MORNING THEN NORTH-
NORTHWEST BY AFTERNOON.
LENNING
//DISCUSSION...UPDATED 06Z...
LARGER SCALE SWATH OF SNOW HAS MOSTLY SLID SOUTH OF THE ORD/MDW
AREA BUT A BROAD LAKE EFFECT BAND IS SUPPORTING CONTINUED LIGHT
SNOW WITH BLOWING SNOW. EXPECT THIS BAND TO PERSIST INTO THE
MORNING AND LIKELY INTENSIFY AT TIMES WHILE GRADUALLY SHIFTING
FROM THE ILLINOIS SIDE TO THE INDIANA END AS WINDS BACK FROM
NORTHEAST TO NORTH NORTHEAST. THE PEAK PERIOD FOR MORE INTENSE
SNOWFALL AT THE ORD/MDW TERMINALS STILL APPEARS TO BE TOWARD
DAYBREAK INTO THE MORNING HOURS BEFORE ACTIVITY DROPS SOUTH.
AS PER THE PREVIOUS DISCUSSION...MODERATE TO HEAVY SNOW IS
POSSIBLE WITH 1/2 TO POTENTIALLY 1/4SM VSBY AT TIMES...WITH
SEVERAL INCHES OF ACCUMULATION DEPENDING ON HOW LONG THE BAND IS
OVERHEAD.
LENNING
//ORD AND MDW CONFIDENCE...UPDATED 06Z...
* HIGH CONFIDENCE IN SNOW INTENSITY/VSBY TRENDS UNTIL DAYBREAK.
* HIGH CONFIDENCE IN LAKE EFFECT SNOW SHOWERS...LOW CONFIDENCE IN
TIMING OF STRONGER BANDS AND LOWER CIGS/VSBYS.
* MEDIUM-HIGH CONFIDENCE THAT STRONGER BANDS WOULD BRING LIFR/IFR
VSBY...MEDIUM CONFIDENCE THAT THE BEST CHANCE FOR LOWEST
CONDITIONS WILL BE FROM AROUND DAYBREAK THROUGH THE MORNING.
* HIGH CONFIDENCE IN WIND TRENDS.

.MARINE...
418 PM CST
MULTIPLE MARINE CONCERNS OVER THE NEXT SEVERAL DAYS:
SMALL CRAFT CONDITIONS THROUGH TOMORROW NIGHT.
HIGH END GALES DEVELOPING LATE FRIDAY AFTERNOON AND CONTINUING INTO
SATURDAY.
THEN THE POTENTIAL FOR GALES AGAIN EARLY NEXT WEEK AS WELL AS HEAVY
FREEZING SPRAY.
THERE WILL BE PERSISTENT NORTHEAST WINDS OF 20 TO 25 KT WITH
OCCASIONAL 30 KT GUSTS FOR THE SOUTHERN HALF OF THE LAKE AND
NEARSHORE AREAS THROUGH LATE TOMORROW AS HIGH PRESSURE SLOWLY SINKS
SOUTH FROM THE UPPER MIDWEST AND LOW PRESSURE STRENGTHENS OVER THE
OHIO VALLEY. ADDING TO THE CONCERN IS THE LIKELIHOOD OF STRONG LAND
LAKE CONVERGENCE DURING THE DAY ON THURSDAY WHICH COULD RESULT IN
LOCAL NORTHERLY WINDS GREATER THAN 30 KT NEAR THE WESTERN SHORE OF
THE LAKE. AT THE SAME TIME...WINDS WILL DIMINISH FOR A TIME TO THE
EAST OF THE CONVERGENCE. WEB CAMS AND SATELLITE VIEW INDICATES
PLENTIFUL ICE COVERAGE...SO AMOUNT OF WAVE ACTION IS UNCERTAIN. ITS
POSSIBLE THAT ANY WAVE ACTION MAY BE JUST BEYOND THE NEARSHORE
AREA...OR THE PERSISTENT WINDS WILL ALLOW FOR FRACTURING OF THE ICE
AND HIGHER WAVES NEAR THE OPEN WATERS. HAVE ERRED ON THE SIDE OF
CAUTION AND CONTINUED WITH AN SCA THROUGH LATE TOMORROW NIGHT FROM
WINTHROP HARBOR TO GARY AND THROUGH MID FRIDAY AM FROM GARY TO MI
CITY.
AS STRONG HIGH PRESSURE SINKS SOUTHEAST OVER THE OHIO VALLEY ON
FRIDAY...FAIRLY ROBUST LOW PRESSURE WILL TRACK FROM THE NORTHERN
PLAINS TO NEAR OR JUST NORTH OF LAKE SUPERIOR BY EARLY SATURDAY.
THIS IS AN EXCELLENT SET-UP FOR HIGH END SOUTH-SOUTHWEST GALES.
CONCERNED THAT WINDS WILL RAMP UP A BIT QUICKER...SO MOVED UP THE
TIMING OF THE GALE WATCH TO 22Z FRIDAY. WILL ALSO NEED AT LEAST AN
SCA FOR THE NEARSHORE STARTING AT THIS TIME. HAVE BUMPED UP SPEEDS
TO 45 KT FRIDAY NIGHT AND THERE COULD BE A PERIOD OF STORM GUSTS
LATE IN THE EVENING BASED ON FORECAST SOUNDINGS. THE GALES WILL
SUBSIDE SATURDAY AFTERNOON...BUT THERE IS VARIANCE IN TIMING OF A
COLD FRONTAL PASSAGE SO ALSO EXTENDED THE END OF THE GALE WATCH TO
22Z. WITH OFFSHORE FLOW...HAVE LESS CONFIDENCE IN NEEDING A GALE
WATCH FOR THE NEARSHORE AREAS SO WILL LET SUBSEQUENT SHIFTS ASSESS.
IN ADDITION...THERE COULD BE MODERATE FREEZING SPRAY UNTIL
TEMPERATURES WARM SOME OVERNIGHT FRIDAY NIGHT.
FINALLY...ANOTHER LOW PRESSURE AREA WILL TAKE SHAPE LATE IN THE
WEEKEND OVER THE OHIO VALLEY AND TRACK TO EASTERN CANADA ON MONDAY
AS IT RAPIDLY DEEPENS. AS THIS OCCURS...EXCEPTIONALLY STRONG AND
COLD HIGH PRESSURE WILL BUILD SOUTHEAST FROM THE NORTHERN PLAINS.
THIS WILL LIKELY SET THE STAGE FOR WESTERLY GALES AT LEAST ON THE
SOUTH HALF ON MONDAY...AS WELL AS THE POTENTIAL FOR HEAVY FREEZING
SPRAY IN THE BITTERLY COLD AIRMASS.
