AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
826 PM CST WED FEB 24 2016

.UPDATE...
820 PM CST

WILL BE MAKING SOME ADJUSTMENTS TO HEADLINES WITHIN THE
HOUR...WITH MAIN IMPACTS REALLY DRIVEN BY THE WINDS NOW. SOME
EXTENSIONS TO THE BLIZZARD WARNING WILL BE MADE IN FAR NORTHWEST
INDIANA PER RECENT REPORTS AND TRENDS. WILL BE CONVERTING OTHER
WARNING AREAS TO ADVISORY. REPORTS FROM NEWTON...JASPER...AND
BENTON COUNTIES INDICATE SOME PATCHY NEAR-BLIZZARD
CONDITIONS...BUT FEEL THE MESSAGE IS BEST SERVED GOING FORWARD
WITH AN ADVISORY IN THESE AREAS.

THE EXPANSIVE AND MATURE CYCLONE HAS A CENTER SPANNING ACROSS
MOST OF MI/IN/OH. ITS MID-LEVEL CENTER WILL NOT MOVE MUCH THE REST
OF TONIGHT AND BECAUSE OF THAT THE WESTERN EDGE OF ITS BROAD LIFT
AND DEFORMATION WILL REMAIN OVER FAR EASTERN ILLINOIS AND
NORTHWEST INDIANA. PER RADAR TRENDS AND SHORT TERM MODEL
SOLUTIONS...OCCASIONAL MESOSCALE FORCING FOR BANDING AND HEAVIER
SNOW WILL CONTINUE THROUGH MIDNIGHT ESPECIALLY OVER LAKE AND
PORTER COUNTIES. ADDITIONAL ACCUMULATIONS OF A COUPLE INCHES
ARE LIKELY IN THOSE TWO COUNTIES...WITH SOME GRAND TOTALS IN THE
PLACES HIT THE HARDEST TODAY LIKELY REACHING OR EXCEEDING 15
INCHES.

THE WINDS WILL REMAIN STOUT FOR SEVERAL MORE HOURS ACROSS
NORTHWEST INDIANA WHERE GUSTS TO 30 TO 45 MPH HAVE BEEN REGULAR
SINCE LATE AFTERNOON...AND 45 MPH PLUS OBSERVED AND INFERRED
ACROSS NORTHERN LAKE AND PORTER COUNTIES. WITH CONTINUED
SNOWFALL OVER THIS AREA...EVEN THOUGH DIMINISHING IN
INTENSITY...EXPECTING VISIBILITY TO BE REGULARLY QUITE LOW...THUS
JUSTIFYING AN EXTENSION OF THE BLIZZARD WARNING FOR THOSE TWO
COUNTIES.

LIGHT SNOW WILL OCCUR AT TIMES OVER FAR NORTHEAST AND EASTERN
ILLINOIS THROUGH MUCH OF TONIGHT...BUT LITTLE ADDITIONAL
ACCUMULATION ANTICIPATED. TEMPERATURES LOOK TO NOT FALL BELOW
FREEZING UNTIL POSSIBLY VERY LATE. WHERE THERE IS SOME MELTED SNOW
THAT POSSIBLY COULD CAUSE A FEW SLICK SPOTS.

MTF

&&

.SHORT TERM...
226 PM CST

REST OF TODAY THROUGH THURSDAY EVENING...

MODERATE TO HEAVY SNOW CONTINUES ACROSS PORTIONS OF NORTHEASTERN
ILLINOIS AND NORTHWESTERN INDIANA THIS AFTERNOON WITH LATEST RADAR
IMAGERY SHOWING SOME OF THE HEAVIEST SNOWFALL OCCURRING OVER THE
CHICAGO METRO INTO FAR NORTHWEST INDIANA. PORTIONS OF NORTHWEST
INDIANA HAVE ALREADY SEEN SOMEWHERE IN THE BALLPARK OF HALF A FOOT
OF SNOW WITH A FEW MORE INCHES POSSIBLE AS WE HEAD THROUGH THE
REMAINDER OF THE AFTERNOON INTO EARLY EVENING HOURS...WITH THE
GREATEST ACCUMULATIONS FOCUSED NEAR AND EAST OF THE I-57 CORRIDOR.
HEAVY BAND OF SNOW EARLIER TODAY WAS PRIMARILY TIED TO AREA OF
H7 FRONTOGENESIS WHICH NEAR TERM GUIDANCE SUGGESTS IS SHIFTING OFF
TO OUR NORTHEAST FOR THE REMAINDER OF THE AFTERNOON.
MEANWHILE...MID LEVEL WARM AIR ADVECTION AND ISENTROPIC ASCENT
FOCUSED ALONG AN AXIS STRETCHING FROM NEAR VPZ SW THROUGH NEAR CMI
WILL CONTINUE THROUGH THE REMAINDER OF THE AFTERNOON...THEN IS
ALSO PROGGED TO BEGIN SHIFTING NORTHEAST AFTER 00Z AND WOULD
EXPECT SNOWFALL INTENSITY TO QUICKLY WANE ACROSS THE FORECAST AREA
THEREAFTER...AND ALSO BECOME FOCUSED MAINLY OVER NORTHWEST INDIANA
AS WE NEAR 06Z. WINDS REMAIN BREEZY THROUGH THE EVENING AND ARE
PROGGED TO BACK SLIGHTLY TOWARDS THE NNW. DESPITE THE SNOWFALL
GENERALLY BEING WET AND DENSE...EMERGENCY MANAGERS HAVE REPORTED
BLOWING SNOW AND DRIFTING IN OPEN AREAS RESULTING IN ADDITIONAL
CHALLENGES FOR ROAD CREWS AND WOULD ANTICIPATE THIS TO CONTINUE
LATE INTO THE EVENING AND POSSIBLY THE OVERNIGHT HOURS.

QUIETER CONDITIONS EXPECTED ACROSS THE LOCAL AREA THURSDAY.
MID/UPPER LEVEL RIDGE IS PROGGED TO BUILD FROM THE MID MISSOURI
VALLEY INTO THE UPPER MISSISSIPPI VALLEY WITH HEIGHT RISES
OVERSPREADING NORTHERN ILLINOIS AND NORTHWEST INDIANA. DESPITE
MID-UPPER LEVEL SUBSIDENCE AND DRYING...STEEP LOW LEVEL LAPSE
RATES ARE EXPECTED TO DEVELOP DURING THE DAY WITH TOP OF THE
MIXED LAYER POKING INTO THE SNOW GROWTH ZONE. THIS COULD PRODUCE
SOME LIGHT SNOW FROM THE LOW LEVEL STRATOCUMULUS...HOWEVER
SHALLOW CLOUD DEPTH SHOULD LIMIT THE INTENSITY OF SNOW TO JUST A
FEW FLURRIES. ANTICIPATE BREEZY CONDITIONS WILL CONTINUE HOWEVER
AS WE REMAIN UNDER A MODERATE NORTHERLY GRADIENT AHEAD OF THE
APPROACHING SURFACE HIGH. EXPECT HIGH TEMPERATURES IN THE LOW TO
MID 30S.

DEUBELBEISS

&&

.LONG TERM...
239 PM CST

THURSDAY NIGHT THROUGH WEDNESDAY...

DEEP SURFACE LOW PRESSURE FROM TODAYS STORM WILL BE LIFTING OUT
ACROSS THE CANADIAN MARITIME PROVINCES THURSDAY NIGHT...AS HIGH
PRESSURE SETTLES SOUTH-SOUTHEAST ACROSS THE SOUTHERN PLAINS AND
GULF COAST REGION. GUIDANCE IS IN GOOD AGREEMENT IN DIGGING A
QUICK MOVING LOW-AMPLITUDE SHORT WAVE SOUTHEAST ACROSS THE AREA
FRIDAY EVENING... WITH A REINFORCING PUSH OF LOW-LEVEL COLD
ADVECTION IN WHICH FORECAST SOUNDINGS DEEPEN THE MIXED LAYER AND
DEPICT ENOUGH INSTABILITY FOR SOME SCATTERED FLURRIES/LIGHT SNOW
SHOWERS. LAKE EFFECT SNOW SHOWERS ARE LIKELY...THOUGH FOCUSED JUST
OFF TO THE EAST OF THE CWA FOR THE MOST PART WITH NORTHWEST FETCH
EVENTUALLY BECOMING MORE WESTERLY BY EARLY FRIDAY. ANOTHER MID-
LEVEL WAVE DROPS ACROSS THE WESTERN LAKES FRIDAY...THOUGH BY THAT
TIME LOW LEVEL FLOW IS BACKING AND BECOMING ANTI-CYCLONIC AND LESS
LIKELY TO SUPPORT SHALLOW CONVECTIVE FLURRIES/SNOW SHOWERS
ESPECIALLY BY FRIDAY AFTERNOON. TEMPS LOOK SEASONABLY COOL IN THE
MID-30S.

UPPER RIDGE OVER WESTERN CONUS FRIDAY MOVES EAST AND BROADENS
SATURDAY...DOWNSTREAM OF A SHORT-WAVE TROUGH MOVING QUICKLY EAST
ACROSS THE CENTRAL ROCKIES. SURFACE HIGH PRESSURE RIDGE SHIFTS
EAST OF THE CWA BY FRIDAY EVENING WITH WEST-SOUTHWEST LOW-LEVEL
WINDS AND WARM ADVECTION DEVELOPING ACROSS THE REGION. THIS IS
ENHANCED BY SURFACE LOW PRESSURE DEVELOPING/DEEPENING NORTH OF THE
GREAT LAKES ACROSS ONTARIO IN RESPONSE TO A STRONG JET STREAK
CROSSING THE TOP OF THE UPPER RIDGE. THIS SETS UP WARMER TEMPS FOR
THE AREA SATURDAY AS 925MB TEMPS RISE INTO THE +6/7C RANGE. THIS
SHOULD PRODUCE TEMPS AROUND 50 ACROSS MUCH OF THE AREA...THOUGH
LIKELY HOLDING IN THE 40S OVER SNOW PACK IN NORTHWEST INDIANA.

UPPER TROUGH APPROACHES SUNDAY WITH A SECOND SURFACE LOW
DEVELOPING ACROSS THE UPPER MISSISSIPPI VALLEY AND MOVING EAST
ACROSS THE REGION BY EVENING. WHILE RAISING TEMPS FURTHER...THIS
ALSO BRINGS THE POTENTIAL FOR SOME LIGHT RAIN ESPECIALLY LATER IN
THE DAY/EVENING ON SUNDAY. 925MB TEMPS WARM TO +8/12C BETWEEN
GLOBAL GUIDANCE (WARMEST IN THE ECMWF). HAVE SPLIT THE DIFFERENCE
AT THIS DISTANCE WITH MID-50S FOR MUCH OF THE AREA SUNDAY BEFORE
COLD FROPA.

UPPER LEVEL FLOW FLATTENS EARLY NEXT WEEK...WITH MODELS DEPICTING
THE LOW LEVEL BAROCLINIC ZONE ORIENTED WEST-EAST ACROSS THE
REGION. MOST GUIDANCE HAS US JUST TO THE COOL SIDE OF THE
BOUNDARY...THOUGH TEMPS NEAR/A LITTLE ABOVE CLIMO WITH HIGHS IN
THE UPPER 30S TO MID 40S. PRECIP CHANCES APPEAR GREATEST TUESDAY-
WEDNESDAY AS MORE AMPLIFIED WAVE APPROACHES.

RATZER

&&

.AVIATION...
FOR THE 00Z TAFS...

SNOW CONTINUES TO FALL ACROSS ALL BUT KRFD LATE THIS AFTERNOON.
CURRENT INDICATIONS SUGGEST THAT SNOW WILL CONTINUE TO FALL THROUGH
MUCH...IF NOT ALL OF THIS EVENING OVER THE FAR EASTERN TERMINALS. AS
SUCH...I HAVE CONTINUED 1-2 SM VISIBILITIES THROUGH LATER THIS
EVENING AT KORD AND KMDW. I ALSO HAVE ADDED A TEMPO FOR CONDITIONS
AS LOW AS 3/4SM THROUGH MID EVENING AT THESE SITES. IT APPEARS THAT
CONTINUED FORCING FOR ASCENT ON THE BACK SIDE OF THE MID LEVEL LOW
WILL CONTINUE TO SUPPORT SNOW WITH VISIBILITIES BRIEFLY FALLING
BELOW A MILE. BLIZZARD CONDITIONS WITH VISIBILITIES OF 1/4SM ARE
EXPECTED TO CONTINUE INTO TONIGHT AT KGYY WITH NORTHERLY WINDS
CURRENTLY GUSTING UP AROUND 50KT.

ANY LINGERING SNOW SHOULD END LATER TONIGHT OVER THE AREA.
ADDITIONALLY...WINDS WILL GRADUALLY ABATE ON THURSDAY...WITH
IMPROVED CONDITIONS.

.MARINE...
202 PM CST

PRIMARY FOCUS OF LAKE MICHIGAN MARINE FORECAST IS IN THE NEAR
TERM... WITH NORTHERLY STORM FORCE/HIGH GALE EVENT CONTINUING
THROUGH TONIGHT AND EVENTUALLY RAMPING DOWN DURING THE DAY
THURSDAY.

DEEP SURFACE LOW PRESSURE WAS OVER THE OHIO VALLEY NEAR
CINCINATTI THIS AFTERNOON...AND WILL LIFT NORTHEAST ACROSS LAKE
ONTARIO AND INTO FAR SOUTHEAST BY THURSDAY MORNING. OBSERVING
LOCATIONS ALONG SOUTHERN LAKE MICHIGAN HAVE BEEN DEPICTING WINDS
OCCASIONALLY GUSTING 45+ KTS SINCE LATE MORNING...AND FORECAST
SOUNDINGS INDICATE A DEEPENING OF THE MIXED LAYER AND THE
POTENTIAL FOR GUSTS 45-50 KT LATE THIS AFTERNOON THROUGH THIS
EVENING BEFORE EASING SLOWLY AFTER MIDNIGHT. BASED ON THIS WILL
LEAVE STORM WARNING AS IS ON SOUTHERN PORTION OF THE LAKE WITH
GALES ON THE NORTH...THOUGH IT IS POSSIBLE THAT THE STORM WARNING
COULD BE REPLACED WITH GALES A LITTLER EARLIER THAN THE CURRENT 7
AM CST THURSDAY EXPIRATION. OTHERWISE...NORTH WINDS SHOULD BACK
NORTH- NORTHWEST THURSDAY...AND GRADUALLY DIMINISH THROUGH THE DAY
AND LIKELY FALLING BELOW GALE FORCE BY EVENING AS THE LOW TRACKS
AWAY ACROSS THE ST LAWRENCE VALLEY. SURFACE HIGH PRESSURE WILL
THEN BUILD SOUTHEAST ACROSS THE PLAINS TO THE TEXAS GULF COAST AND
LOWER MISSISSIPPI VALLEY ON FRIDAY...WITH WEAKER RIDGING EXTENDING
NORTH ACROSS THE WESTERN LAKES. THE RIDGE WILL MOVE EAST OF THE
LAKE FRIDAY AFTERNOON...WITH WINDS BECOMING WEST-SOUTHWEST AND
INCREASING INTO THE 20-25 KT RANGE FRIDAY NIGHT INTO SATURDAY...AS
ANOTHER AREA OF LOW PRESSURE MOVES ACROSS ONTARIO.
