DAKOKTAS INTO WESTERN ONTARIO AND THIS WILL MOVE OVER THE AREA
TONIGHT INTO EARLY THURSDAY. IN NEAR TERM...WILL CONTINUE TO SEE
OCCASIONAL FLURRIES...WITH LINGERING SNOW SHOWERS EXITING NW
INDIANA. FORCING FROM UPPER WAVE/PV ANOMALY AND STEEPENING OF
LAPSE RATES SHOULD RESULT IN FAIRLY WIDESPREAD SCATTERED SNOW
SHOWERS PIVOTING SOUTHEASTWARD FROM AROUND MIDNIGHT TONIGHT
THROUGH EARLY THURSDAY MORNING. SIMILAR TO PREVIOUS OCCURRENCES
WITHIN THE PAST WEEK...NOT ALL AREAS WILL SEE ACCUMULATIONS...BUT
WOULDNT BE SURPRISED IF HEAVIER SNOW SQUALLS ARE EMBEDDED WITHIN
SCATTERED SNOW SHOWER ACTIVITY...YIELDING LOCALLY 1/2 INCH TO 1
INCH ACCUMS AND SIGNIFICANTLY REDUCED VISIBILITY. COLD ADVECTION
SHOULD FORCE TEMPERATURES DOWN TO ROUGHLY 0 TO +6 RANGE BY
DAYBREAK WEDNESDAY.

TEMPERATURE TRENDS ARE TRICKY ON WEDNESDAY BECAUSE OF HOW ANOMALOUS
AIR MASS IS. MINUS MID TO UPPER 20SC AIRMASS AT 850 MB PROGGED BY
LATE IN THE DAY IS AMONGST THE COLDEST OBSERVED AT ILX/DVN IN THE
MONTH OF FEBRUARY...AND ESPECIALLY THIS LATE IN THE MONTH. HAVE
SHOWN A VERY MINIMAL RECOVERY FROM MORNING LOWS INTO MID DAY/HIGHS
MID TO HIGH POSITIVE SINGLE DIGITS/FOLLOWED BY A FALL IN THE
AFTERNOON..BUT THIS VERY WELL COULD BE OVERDONE. BEST FORCING WILL
BE OFF TO EAST...BUT DEEP UPPER TROUGH REMAINING OVERHEAD AND STEEP
LOW LEVEL LAPSE RATES SHOULD KEEP AT LEAST ISOLATED SNOW SHOWERS AND
FLURRIES AROUND INTO EARLY WEDNESDAY AFTERNOON. STRONG LOW LEVEL
COLD ADVECTION WILL CONTINUE THROUGH WEDNESDAY NIGHT...WITH 925 MB
TEMPS IN THE MID MINUS 20SC BY EARLY THURSDAY. THUS DESPITE HIGH
PRESSURE REMAINING WELL NORTHWEST AND PRECLUDING RADIATIONAL
COOLING...SUBZERO LOWS ARE EXPECTED CWA WIDE...AND RELATIVELY
UNIFORM RANGING FROM MID MINUS SINGLE DIGITS TO AROUND 10 BELOW.
EVEN DOWNTOWN CHICAGO SHOULD FALL TO SEVERAL DEGREES BELOW ZERO.
WILL NEED A WIND CHILL ADVISORY FOR THE ENTIRE CWA WEDNESDAY
EVENING/NIGHT THROUGH THURSDAY MORNING...WITH LOWEST VALUES
RANGING FROM 20 TO 30 BELOW ZERO.

THERMAL TROUGH WILL ONLY SLOWLY DEPART TO THE NORTHEAST ON
THURSDAY...SO AFTER BITTERLY COLD START TO DAY...CONTINUE TO
FORECAST RECORD/NEAR RECORD LOW HIGH TEMPERATURES IN THE LOW TO MID
POSITIVE SINGLE DIGITS. SEE CLIMATE SECTION FOR ADDITIONAL DETAILS.

REGARDING LAKE EFFECT POTENTIAL ON WEDNESDAY INTO WEDNESDAY
NIGHT...GUIDANCE CONTINUES TO FOCUS MAINLY EAST OF PORTER COUNTY
WITH WNW BOUNDARY LAYER FLOW. HOWEVER...WITH EXTREME COLD AIR MASS
OVER RELATIVELY MILD LAKE WATERS...COULD STILL SEE SOME MINOR
ACCUMULATIONS IN NORTHEAST PORTER COUNTY IN LIGHT MULTIBAND SNOW
SHOWERS.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 20Z...

* GUSTY WLY-WNWLY WINDS TO 20 KT THROUGH LATE THIS AFTERNOON.

* OCNL -SHSN THROUGH SUNSET.

* POTENTIAL FOR A SHORT PERIOD OF MODERATE SNOW SHOWERS LATE
  TONIGHT WITH PERIODS IFR VIS/MVFR CIGS POSSIBLE.

* GUSTY NWLY WINDS TO 25KT TOMORROW.

KREIN

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

A WEAK COLD FRONT HAS PUSHED THROUGH ALL OF THE TERMINALS...EXCEPT
GYY...AT ISSUANCE TIME. EXPECT THAT THE FRONT SHOULD PUSH PAST GYY
WITHIN THE NEXT HOURS OR SO. FOLLOWING THE FROPA...SCT SNOW
SHOWERS HAVE ENDED AND SKIES ARE IMPROVING TO VFR AND WINDS HAVE
SHIFTED TO GENERALLY NWLY. WITH INCREASED SUNSHINE AND POST FRONTAL
COLD ADVECTION...EXPECT GUSTS TO 20KT THROUGH THE AFTERNOON.

ANOTHER PERIOD OF LIGHT SNOW IS POSSIBLE TONIGHT AS A MID LEVEL
IMPULSE CROSSES THE REGION...AROUND THE SOUTHWESTERN PERIPHERY OF A
BROAD UPPER TROUGH COVERING THE ERN/CNTRL CONUS. SINCE THE AIRMASS
OVER THE REGION IS STILL RELATIVELY DRY...ANTICIPATE ONLY MINOR
ACCUMULATIONS...PERHAPS AROUND 1 INCH...BUT WITH WINDS LIKELY TO
REMAIN ABOVE 10KT THROUGH THE NIGHT...EXPECT THE MAIN IMPACT TO BE
REDUCED VISIBILITY...LIKELY DROPPING INTO IFR LEVELS. GIVEN SOME
UNCERTAINTY TO THE EXACT TIMING OF THE SYSTEM CROSSING THE
AREA...WILL MAINTAIN THE GOING PROB30 GROUP...BUT ANTICIPATE THAT
THIS WILL BE UPGRADED TO A TEMPO OR PREVAILING GROUP AS TIMING
BECOMES MORE CERTAIN. FOLLOWING THE PASSAGE OF AN ASSOCIATED SFC
COLD FRONT...VERY COLD AIR WILL FILTER IN ACROSS THE AREA AS
STRONG HIGH PRESSURE BUILDS OVER THE NRN/CNTRL PLAINS AND A WEAK
SFC LOW PRESSURE MOVES THROUGH THE ERN GREAT LAKES. A MODERATE
PRESSURE GRADIENT AND STRONG COLD ADVECTION WILL LEAD TO GUSTY
NWLY WINDS THOUGH THE DAY TOMORROW...WITH GUSTS TO 25KT OR
POSSIBLY HIGHER.

KREIN

//ORD AND MDW CONFIDENCE...UPDATED 20Z...

* MEDIUM TO HIGH CONFIDENCE IN WIND TRENDS THROUGH THE PERIOD.

* MEDIUM TO HIGH CONFIDENCE IN ANOTHER ROUND OF LIGHT SNOW LATE TONIGHT.

* MEDIUM CONFIDENCE IN TIMING AND DURATION OF REDUCED CIGS/VIS
  ASSOCIATED WITH THE SNOW.

* LOW TO MEDIUM CONFIDENCE IN HOW LOW CIGS/VIS WILL DROP DURG
  PERIODS OF SNOW.

//OUTLOOK FOR ORD/MDW FOR 00Z THURSDAY-12Z TUESDAY...UPDATED 12Z...

WEDNESDAY NIGHT...VFR WITH WEST-NORTHWEST WINDS.

THURSDAY...MAINLY VFR. NORTHWEST WINDS.

FRIDAY...CHANCE OF SNOW. IFR POSSIBLE. GUSTY SOUTH WINDS.

.MARINE...
148 AM CST

A PERIOD OF STRONG NORTHWESTERLY WINDS WILL SET UP ACROSS THE LAKE
ON WEDNESDAY AS THE GRADIENT TIGHTENS IN RESPONSE TO THE APPROACH OF
AN ARCTIC SURFACE HIGH OVER THE NORTHERN PLAINS. IT APPEARS THESE
STRONG NORTHWEST WINDS WILL CONTINUE WEDNESDAY NIGHT...WITH A SOLID
30 KT OF WIND EXPECTED. IT ALSO APPEARS THAT SOME 35 KT GALES COULD
OCCUR AT TIMES ACROSS THE SOUTH END OF LAKE MICHIGAN DURING THIS
PERIOD. ALTHOUGH THIS APPEARS TO BE A MARGINAL EVENT FOR GALES...IF
ANY GOOD CONVERGENT BANDS OF LAKE EFFECT SNOW SET UP...THIS COULD
PRODUCE PERIODS OF LOCALLY STRONGER WINDS OVER SOUTHERN AND
EASTERN PORTIONS OF THE LAKE. THEREFORE...I HAVE OPTED TO GO
AHEAD WITH A GALE WATCH FOR WEDNESDAY AND WEDNESDAY NIGHT OVER
SOUTHERN LAKE MICHIGAN...EXCLUDING THE NEAR SHORE WATERS. I WILL
ALSO INCLUDE A HEAVY FREEZING SPRAY WATCH FOR THESE SAME AREAS DUE
TO THE VERY COLD AIRMASS EXPECTED CONCURRENTLY WITH THESE STRONG
WINDS.

WINDS WILL EASE BAY THURSDAY AS THE SURFACE RIDGE OF HIGH PRESSURE
BEGINS TO SHIFT OVER THE WESTERN LAKES REGION. HOWEVER...IT APPEARS
THAT WINDS WILL QUICKLY PICK UP OUT OF THE SOUTH BY FRIDAY AS
ANOTHER CLIPPER SYSTEM TRACKS ACROSS SOUTHERN CANADA. THIS COULD
RESULT IN 30 KT SOUTHERLY WINDS AND MORE FREEZING SPRAY LAKE-WIDE ON
FRIDAY.
