AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
208 AM CST WED JAN 18 2012

.DISCUSSION...
759 PM CST

FOR EVENING UPDATE...

SNOW IS RAPIDLY DIMINISHING/ENDING FROM WEST TO EAST ACROSS THE AREA
EARLY THIS EVENING...WITH RAPID CLEARING WORKING ACROSS THE AREA.
FORECAST REMAINS ON TRACK...AND HAVE ONLY UPDATED GRIDS/FORECAST PER
CURRENT RADAR/OBS/SATELLITE TRENDS OF ENDING PRECIP AND CLEARING
SKIES.

GOES VAPOR IMAGERY INDICATES MID-LEVEL SHORT WAVE TROUGH AXIS
ROUGHLY FROM SOUTHERN LOWER MICHIGAN TO EAST CENTRAL IL AT
0130Z...HAVING PASSED THROUGH ALL BUT EASTERN COUNTIES OF THE CWA.
11-3.9 MICRON IR LOOP SHOWS CLEARING LINE FROM ROUGHLY UGN...JOT AND
PNT AREA...AND SHOULD SEE SKIES CONTINUE TO CLEAR INTO FAR EAST
CENTRAL IL AND NORTHWEST INDIANA OVER THE NEXT COUPLE OF HOURS.
EXCEPTION MAY BE ACROSS FAR NORTHEAST PORTER COUNTY...WHERE FORECAST
SOUNDINGS MAINTAIN WINDS IN THE 300-330 DEGREE RANGE OFF THE LAKE
OVERNIGHT...THOUGH EVEN THERE A STRENGTHENING SUBSIDENCE INVERSION
AND EVENTUAL BACKING OF WINDS TO A MORE WEST-NORTHWEST DIRECTION BY
MORNING SHOULD LIMIT THE POTENTIAL FOR MUCH IN THE WAY OF ORGANIZED
LAKE-INDUCED SNOW SHOWERS.

MAIN QUESTION FOR OVERNIGHT PERIOD IS JUST HOW LOW TEMPS WILL GET.
ARCTIC AIR PUSHING ACROSS IA/MN/WESTERN WI INTO THE REGION WHERE
TEMPS ARE ALREADY IN THE SINGLE DIGITS. SURFACE RIDGE MOVES INTO
NORTH CENTRAL IL BY MORNING...WHERE A FEW INCHES OF NEW SNOWFALL
WILL AID LIGHT WINDS/CLEAR SKIES IN SETTING UP STRONG RADIATIONAL
COOLING CONDITIONS. GOING FORECAST ALREADY ABOUT A CATEGORY BELOW
GUIDANCE TEMPS WITH LOWS AROUND ZERO...BUT WILL CONTINUE TO MONITOR
TRENDS OVER THE NEXT COUPLE OF HOURS FOR ANY NECESSARY ADJUSTMENTS.

RATZER

//PREV DISCUSSION...
310 PM CST

THIS AFTERNOON AND EVENING...

WILL CANCEL SNOW HEADLINES FOR NORTHERN ILLINOIS WITH THE
AFTERNOON FORECAST PACKAGE AS MORE FAVORABLE FORCING SHIFTS TO THE
EAST AND RADAR CONTINUES TO SHOW WEAKENING TRENDS. SNOW WILL
CONTINUE TO TAPER OVER NEXT FEW HOURS WITH PASSAGE OF H7 TROUGH
WITH A FEW LINGERING FLURRIES INTO THE EVENING. AREAS THAT HAVE
SEEN SNOW ACCUMULATIONS MAY CONTINUE TO SEE SOME BLOWING THROUGH
THE EVENING AS WINDS STAY ELEVATED. BMD

LATER TONIGHT THROUGH TUESDAY...

FAIRLY ACTIVE WEATHER PATTERN WITH SIGNIFICANT TWISTS AND TURNS
AHEAD...INCLUDING A BRUSH WITH TRUE ARCTIC AIR FOLLOWED BY A RETURN
TO MUCH ABOVE AVERAGE TEMPS BY NEXT WEEK.

FOR TONIGHT...SYSTEM AFFECTING THE AREA PRESENTLY LOOKS TO REMAIN
QUITE PROGRESSIVE AND DESPITE SHARP FRONTAL INVERSION SATELLITE
OBSERVATIONS/TRENDS CERTAINLY SUPPORT GUIDANCE FORECAST OF SKIES
CLEARING OUT THIS EVENING. HAVE FOLLOWED THAT TREND IN THE GRIDS
THIS EVENING WHICH THEN PRESENTS CHALLENGES WITH TEMPS TONIGHT.

NORTHERN EXTENT OF THE SURFACE RIDGE AXIS LOOKS TO MOVE INTO THE
AREA OVERNIGHT WHICH SHOULD ALLOW WINDS TO QUICKLY DIMINISH. CLEAR
SKIES AND LIGHT WINDS LOOK FAVORABLE FOR STRONG RADIATIONAL COOLING
DESPITE WARM ADVECTION COMMENCING ABOVE THE BOUNDARY LAYER AFTER
MIDNIGHT. FAIRLY GOOD RADIATIONAL COOLING SET-UP COMBINED WITH FRESH
SNOW COVER SHOULD ALLOW TEMPS TO FALL BELOW GUIDANCE TO NEAR OR
BELOW ZERO NORTH CENTRAL ILLINOIS. ACTUALLY WOULDNT BE SURPRISED TO
SEE THE COLDEST SITES COME IN BETWEEN 5 AND 10 BELOW...THOUGH
CONFIDENCE ISNT HIGH ENOUGH TO GO THAT LOW IN THE GRIDS.

WARM AIR ADVECTION RAMPS UP WEDNESDAY WITH INCREASING SOUTHERLY
WINDS AS CYCLOGENESIS TAKES PLACE OVER THE NORTHERN PLAINS. TEMPS
ONCE AGAIN QUITE A CONUNDRUM AS WE LIKELY START OFF QUITE CHILLY BUT
INCREASING SOUTHERLY FLOW SHOULD ALLOW FOR LATE AFTERNOON HIGHS AND
PROBABLY STEADY IF NOT SLOWLY RISING TEMPS WEDNESDAY NIGHT UNTIL
FROPA OCCURS LATE WED NIGHT/EARLY THURS MORNING. ADJUSTED LOW TEMPS
UPWARD AS IT LOOKS LIKE MOST OF THE NIGHT WILL BE SPENT IN THE
"WARM" SECTOR WITH READINGS IN THE 20S IF NOT A BIT WARMER. FRONT
SHOULD BE IN CWA AT 12Z THURS WHICH COMPLICATES FORECAST LOW TEMPS
WHICH IN ALL LIKELIHOOD WILL TURN INTO THE HIGH TEMPS THURS WITH
STEADY/SLOWLY FALLING TEMPS DURING THE DAY THURSDAY IN STRONG COLD
AIR ADVECTION REGIME. THURSDAY LOOKS TO BE OUR BRUSH WITH THE
COLDEST AIR MASS OF THE SEASON WITH DAYTIME TEMPS FALLING INTO THE
SINGLE DIGITS OVER FRESH SNOWPACK AND LOW/MID TEENS ELSEWHERE.

PATTERN REMAINS UBER PROGRESSIVE WITH SURFACE HIGH BUILDING THURS
EVENING AND PROBABLY ALLOWING FOR LOW TEMPS OCCURRING PRIOR TO
MIDNIGHT BEFORE CLOUD INCREASE SLOWS AND EVENTUALLY HALTS TEMP FREE
FALL. LOW TEMPS WILL HINGE ON THE ARRIVAL OF THE CLOUDS...SLOWER
ARRIVAL OF CLOUDS COULD ALLOW TEMPS TO DIP BELOW ZERO IN OUTLYING
AND PARTICULARLY SNOW COVERED AREAS BEFORE LEVELING OFF.

MODELS ARE IN SURPRISINGLY GOOD AGREEMENT ON THEIR HANDLING OF
PACIFIC SHORTWAVE PROGGED TO BEGIN AFFECTING THE AREA FRIDAY.
CURRENT FORECAST TRACK WOULD FAVOR A BAND OF ACCUMULATING SNOW FROM
SOUTHERN MN/NORTHERN IA EAST INTO SOUTHERN WI/NORTHERN IL. HAVE
INCREASED POPS A BIT FAR NORTHERN COUNTIES...BUT IMPORTANT TO KEEP
IN MIND THAT THE SYSTEM IS FAIRLY LOW AMPLITUDE AND STILL THOUSANDS
OF MILES OFFSHORE AND UNSAMPLED BY UPPER AIR NETWORK SO FORECAST
TRACK IS FAR FROM ETCHED IN STONE. ANY SHIFT TO THE TRACK OF THIS
LOW COULD RESULT IN PRETTY BIG DEVIATIONS TO THE FORECAST.

THIS WEEKEND INTO NEXT WEEK...MEDIUM RANGE MODELS ALLOW THE POLAR
VORTEX TO RETROGRADE WESTWARD TOWARD ALASKA WITH POSITIVE HEIGHT
DEVELOPING IN THE EASTERN SUBTROPICAL NORTH PACIFIC. THE RESULT WILL
BE A STRONG PACIFIC JET WITH PRIMARILY ZONAL FLOW ACROSS THE CONUS
WITH PATTERN SWITCHING BACK TO ONE MORE SIMILAR TO WHAT WE SAW THE
FIRST 6 WEEKS OF WINTER. TEMPERATURES WILL LIKELY REBOUND BACK TO
ABOVE AVERAGE AND PROBABLY MUCH ABOVE AVERAGE BY EARLY/MIDDLE PART
OF NEXT WEEK. HAVE ADJUSTED MODEL BLENDED GRIDDED TEMPS
UPWARD...ESPECIALLY LOW TEMPS WITH ANY RESIDUAL SNOW LIKELY TO BE
GONE BY EARLY NEXT WEEK. MODELS ARE ALL OVER THE PLACE WITH THEIR
HANDLING OF SHORTWAVES TRAVERSING THE ZONAL FLOW RESULTING IN
SEVERAL CHANCES OF RAIN/SHOWERS NEXT WEEK AS DISTURBANCES ZIP BY
THE AREA.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 08Z...

* STRONG/GUSTY SOUTHERLY/SOUTHWESTERLY WINDS DEVELOPING BY LATE
  THIS AFTERNOON...CONTINUING THIS EVENING AND SHIFTING NORTHWEST
  THURSDAY MORNING. CMS

//DISCUSSION...UPDATED 06Z...

HIGH PRESSURE ACROSS MISSOURI LATE THIS EVENING WILL BUILD
EASTWARD ACROSS ILLINOIS OVERNIGHT. THIS WILL LEAD TO A STEADY
DECREASE IN THE WIND SPEEDS BY EARLY MORNING. THIS WILL BE SHORT
LIVED...HOWEVER...AS A FAST MOVING CLIPPER SYSTEM MOVES ACROSS THE
UPPER MISSISSIPPI RIVER VALLEY DURING THE AFTERNOON ON WEDNESDAY.
THIS WILL CAUSE SOUTHERLY WINDS TO INCREASE LATER IN THE DAY AS
STRONG PRESSURE FALLS OCCUR AHEAD OF THE SURFACE LOW. BY WEDNESDAY
EVENING GUSTS AROUND 25 KT ARE EXPECTED.

LATER IN THE PERIOD...BY EARLY THURSDAY MORNING...A STRONG COLD
FRONT WILL PUSH ACROSS THE AREA. WINDS WILL SWITCH TO THE WEST
NORTHWEST AND BECOME GUSTY UP TO 30 KT FOR A PERIOD AS STRONG COLD
AIR ADVECTS ACROSS THE AREA. THERE IS ALSO A SLIGHT CHANCE FOR
SOME LIGHT SNOW FOLLOWING THE FRONTAL PASSAGE EARLY ON THURSDAY.
HOWEVER...IT APPEARS THIS WILL BE AROUND THE END OF THE ORD TAF
PERIOD.

.MARINE...
231 PM CST

THE VERY PROGRESSIVE PATTERN WILL CONTINUE TO AFFECT LAKE MICHIGAN
FOR THE NEXT SEVERAL DAYS.

NORTH TO NORTHWEST GALES SHOULD PERSIST OVER THE LAKE THROUGH THE
EVENING AS DEEPENING LOW PRESSURE TRACKS FROM NEAR DETROIT TO
SOUTHERN QUEBEC TONIGHT.  A RIDGE OF HIGH PRESSURE WILL BUILD ACROSS
THE UPPER MIDWEST AND INTO THE WESTERN GREAT LAKES REGION LATE
TONIGHT...ALLOWING WINDS TO SUBSIDE...BUT WAVES SHOULD REMAIN HIGH
OVER THE SOUTHERN PORTIONS OF THE LAKE INTO WEDNESDAY BEFORE
SETTLING DOWN BELOW SMALL CRAFT ADVISORY LEVELS.  HOWEVER...THE
PERIOD OF TIME WITHOUT A MARINE HAZARD HEADLINE WILL BE BRIEF AS
ANOTHER DEEPENING LOW PRESSURE SYSTEM DROPS OUT OF THE NORTHERN
ROCKIES AND MOVES INTO THE WESTERN GREAT LAKES WEDNESDAY NIGHT.
INCREASING SOUTHERLY WINDS ARE EXPECTED AHEAD OF THIS LOW...AND
SINCE THE HIGH WILL BE SLOW TO MOVE OFF TO THE EAST...THE RESULTANT
STRONG PRESSURE GRADIENT MAY LEAD TO MORE GALES OVER THE LAKE. THE
LOW WILL DRAG A COLD FRONT ACROSS THE LAKE LATE WEDNESDAY NIGHT OR
EARLY THURSDAY MORNING...AND THE PUSH OF COLD AIR BEHIND THE FRONT
WILL LIKELY KEEP GALES GOING INTO THURSDAY AFTERNOON.  A SLOWER
MOVING HIGH PRESSURE SYSTEM SHOULD THEN BUILD ACROSS THE UPPER
MISSISSIPPI VALLEY INTO THE OHIO VALLEY LATE THIS WEEK AND INTO THE
WEEKEND.
