Cold in Illinois, December 24, 2013

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
608 AM CST TUE DEC 24 2013

.DISCUSSION...
511 AM CST

A BAND OF LIGHT SNOW CONTINUES TO WORK SOUTHWARD ACROSS FAR
NORTHEAST IL FROM MC HENRY COUNTY SOUTHEAST TO CHICAGO IN
CONJUNCTION WITH THE PASSAGE OF AN UPPER TROUGH AXIS. A BAND OF
LAKE EFFECT SNOW CONTINUES TO DEVELOP NORTH OF THIS LIGHT SNOW
WITH CONVERGENCE FOCUSED OUT OVER THE MIDDLE OF THE LAKE BUT
ARCHING SOUTHWESTWARD. THE MAIN CORRIDOR OF DEVELOPMENT IS
BEGINNING TO SHIFT EASTWARD OFF OF KENOSHA TOWARD MID LAKE BUT
SOME OF THE INITIAL ACTIVITY CONTINUES TO MOVE SOUTHWEST WITH ONE
SMALL AREA CURRENTLY OFF WAUKEGAN SHOWING GOOD INTENSITY ON RADAR.
THIS WILL CONTINUE SOUTHWEST AND WORK ACROSS FAR SOUTHEAST LAKE
AND MUCH OF CENTRAL AND NORTHERN COOK COUNTY OVER THE NEXT HOUR OR
TWO. EARLIER LIGHTER RETURNS GENERATED 1-2SM VSBY IN THE MORE
SYNOPTIC SNOW WITH THIS BAND SHOWING HIGHER REFLECTIVITY. THUS
EXPECT THAT A VERY BRIEF BURST OF SNOW WILL OCCUR WITH VSBY
POSSIBLY LESS THAN A MILE. THE COVERAGE IS FAIRLY COMPACT AND IT
IS MOVING SWIFTLY BUT A TENTH OF TWO OF ACCUMULATION MAY OCCUR AS
IT WORKS INLAND THEN LIKELY DISSIPATES. OTHERWISE EXPECT THE MAIN
LAKE BAND TO CONTINUE TO SHIFT EASTWARD THOUGH IT MAY GRAZE
NORTHERN LAKE AND PORTER COUNTIES IN INDIANA IN THE NEXT FEW
HOURS. HAVE UPDATED NEAR TERM GRIDS TO RAISE POPS FOR A FEW HOURS
TO ACCOUNT FOR THIS.

//PREV DISCUSSION...
315 AM CST

THE MAIN FOCUS THIS MORNING IS SNOW LATER TONIGHT INTO CHRISTMAS
MORNING AS THE FIRST IN A SERIES OF CLIPPERS WORKS ACROSS THE AREA.
EARLY MORNING WATER VAPOR IMAGERY SHOWS A LONGWAVE TROUGH AXIS
SWINGING ACROSS THE AREA ON ITS WAY EAST WITH AN EMBEDDED
CIRCULATION GENERATING SOME LIGHT SNOW FROM MCHENRY COUNTY SOUTHEAST
TO CHICAGO. A NARROW UPPER RIDGE EXTENDS FROM ROUGHLY THE CENTRAL
PLAINS TO HUDSON BAY WHERE IT BECOMES BETTER AMPLIFIED. THE MAIN
FEATURE OF NOTE HOWEVER IS A WELL-DEFINED WAVE TRACKING SOUTHEAST
ACROSS WESTERN MONTANA AND NORTHWESTERN WYOMING. THIS WILL BE THE
CLIPPER TO BRING THE SNOWFALL LATER TONIGHT. ANOTHER MORE SUBTLE
WAVE IS NOTED OVER BRITISH COLUMBIA ON THE DOWN WIND SIDE OF A RIDGE
OVER THE EASTERN PACIFIC. TO THE WEST OF THE RIDGE IS A SERIES OF
UPPER LOWS WHICH ARE MOVING EASTWARD INTO THE RIDGE. AT THE
SURFACE...STRONG HIGH PRESSURE IS CENTERED OVER MISSOURI WITH A
RIDGE AXIS EXTENDING NORTHWARD INTO CENTRAL ONTARIO. SURFACE LOW
PRESSURE ASSOCIATED WITH THE APPROACHING CLIPPER IS OVER
SOUTH-CENTRAL MONTANA.

TODAY...THE UPPER TROUGH AXIS SWINGING ACROSS THE AREA THIS MORNING
WILL SHIFT TO THE EAST AND TAKE THE ASSOCIATED SNOW SHOWERS WITH IT.
A BAND OF LAKE EFFECT WILL BE WORKING SOUTHWARD DOWN LAKE MICHIGAN
BUT BE DIRECTED JUST TO THE EAST OF THE CWA...THOUGH A SHORT PERIOD
OF LIGHT SNOW MAY AFFECT NORTHERN SECTIONS OF PORTER COUNTY.
OTHERWISE...UPPER RIDGING WILL BRIEFLY WORK INTO THE AREA DURING THE
DAY BRINGING WARMER MID LEVEL TEMPS WITH IT. THE SURFACE HIGH WILL
BE TRACKING EASTWARD BRINGING THE RIDGE AXIS OVER THE AREA THROUGH
MIDDAY BEFORE IT SHIFTS EAST AS WELL. THIS WILL ALLOW FOR LIGHT
WINDS THROUGH MOST OF THE DAY WHICH WILL NOT BE SUPPORTIVE OF MIXING
DOWN MUCH OF THE WARMING MID LEVEL AIR LEADING TO ANOTHER CHILLY
DAY. EXPECT HIGHS IN THE SINGLE DIGITS WEST...WHERE THE COLDEST
START WILL BE...TO THE MID/UPPER TEENS EAST. THERE SHOULD BE A GOOD
AMOUNT OF SUNSHINE ACROSS THE AREA...THOUGH NORTHERN SECTIONS OF
NORTH CENTRAL AND NORTHEAST ILLINOIS WILL HAVE SOME LINGERING CLOUD
COVER IN THE MORNING AS THE UPPER TROUGH DEPARTS.

TONIGHT AND CHRISTMAS DAY...THE UPPER LOW CURRENTLY COMING ACROSS
MONTANA WILL CONTINUE SOUTHEAST AND AT LEAST PARTIALLY PHASE WITH A
TROUGH AXIS TO ITS NORTH...WITH THIS PHASING OCCURRING OVER THE
LOCAL AREA TONIGHT. WITH THE SURFACE HIGH TRACKING EASTWARD
SOUTHERLY WINDS WILL INCREASE THIS EVENING AND BECOME RATHER BREEZY
LATER THIS EVENING. THIS WILL SUPPORT A WARMING TREND OVERNIGHT AS
WARMER AIR CONTINUES TO MOVE IN AHEAD OF THE APPROACHING CLIPPER.
THE FIRST PUSH OF BETTER MID LEVEL ASCENT/FRONTOGENESIS SPREADS IN BY
LATE EVENING BUT SATURATION MAY NOT IMMEDIATELY OCCUR ACROSS MUCH OF
THE AREA. THIS MAY CONFINE SNOWFALL TO THE FAR NORTHWEST CWA DURING
THE EARLY EVENING BEFORE IT SPREADS EASTWARD. HOWEVER...THESE TYPES
OF SYSTEMS TEND TO GENERATE SNOWFALL AT THE GROUND RATHER QUICKLY
AND OFTEN MORE QUICKLY THAN SOME PARAMETERS WOULD SUGGEST.
ULTIMATELY EXPECT SOME LIGHT SNOW ACROSS MANY AREAS NORTH OF
INTERSTATE 80 BY MIDNIGHT OR SO. HOWEVER...THE BETTER ORGANIZED
FORCING AND DEEPER LAYER OF MOISTURE WILL LIKELY ARRIVE DURING THE
OVERNIGHT HOURS. FORECAST SOUNDINGS SHOW GOOD ALIGNMENT BETWEEN THE
FORCING/MOISTURE/SNOW GROWTH ZONE FROM LATE EVENING ONWARD THROUGH
DAYBREAK ACROSS THE CENTRAL AND NORTHERN CWA...THOUGH THERE ARE
INDICATIONS THAT MAXIMUM FORCING MAY OCCUR JUST OUTSIDE THE FAVORED
SNOW GROWTH ZONE. THIS COMBINED WITH THE FAIRLY STRONG WINDS WITHIN
THIS LAYER NOTED IN THE PREVIOUS DISCUSSION MAY LEAD TO LESS THAN
OPTIMAL FLAKE SIZE/ACCUMULATION. WITH THE PHASING NOTED ABOVE...THE
PEAK FORCING LOOKS TO OCCUR OVERNIGHT THROUGH DAYBREAK...ESPECIALLY
ACROSS THE EASTERN PART OF THE AREA. THE SNOW WILL THEN BEGIN TO
TAPER OFF FROM WEST TO EAST FROM DAYBREAK THROUGH MID MORNING.
EXPECTED SNOW RATIOS ARE ON THE HIGH SIDE WITH ROUGHLY 16-20:1
EXPECTED WHICH SUPPORTS AMOUNTS IN THE 1 TO 3 INCH RANGE ALONG AND
NORTH OF INTERSTATE 80 WITH 1 TO 2 INCH AMOUNTS CLOSER TO THE
INTERSTATE AND HIGHER AMOUNTS NORTH. AN INCH OR LESS IS EXPECTED
SOUTH OF INTERSTATE 80. THE WAVE NOTED OVER BRITISH COLUMBIA THIS
MORNING WILL BE RACING SOUTHEASTWARD AND CROSS THE AREA LATER
WEDNESDAY AFTERNOON AND WEDNESDAY EVENING BUT WILL BE MUCH LESS
ORGANIZED THAN THE MORNING SYSTEM. HOWEVER...THE WAVE DOES LOOK TO
AMPLIFY AS IT CROSSES THE AREA SO ANY SNOW ASSOCIATED WITH THE
TROUGH MAY INCREASE IN INTENSITY/COVERAGE AS IT TRACKS EASTWARD.
WILL INCREASE POPS BUT KEEP THEM IN THE CHANCE CATEGORY FOR NOW WITH
A FEW TENTHS ACCUMULATION POSSIBLE NORTH OF INTERSTATE 80.
HOWEVER...THESE CLIPPERS HAVE HAD A TENDENCY TO TRACK FURTHER SOUTH
THAN GUIDANCE SUGGESTS SO MAY NEED TO EXPAND POPS SOUTHWARD A BIT IF
THIS THINKING HOLDS. HIGHS CHRISTMAS DAY WILL BE NOTICEABLY WARMER
THANKS TO THE PASSAGE OF THE CLIPPER...WITH READINGS FROM THE UPPER
20S NORTH TO AROUND 30 SOUTH.

THURSDAY AND FRIDAY...WEAK SURFACE HIGH PRESSURE RIDGING WILL CROSS
THE AREA THURSDAY. THE PASSAGE OF THE SECOND TROUGH AND ASSOCIATED
COLD FRONT WILL RESULT IN COLDER HIGHS THURSDAY WITH UPPER TEENS TO
MID 20S EXPECTED. ANOTHER CLIPPER WILL BE WORKING TOWARD THE AREA
THURSDAY AFTERNOON WITH THE SFC LOW TRACKING ACROSS MINNESOTA AND
WISCONSIN. THIS SYSTEM DOES NOT LOOK AS WELL FOCUSED AT THIS POINT
AS IT PREDECESSORS BUT SUSPECT WE MAY SEE GUIDANCE TREND A LITTLE
STRONGER AND MAYBE FURTHER SOUTH WITH IT WHICH WOULD FIT THE TREND
OF CLIPPERS THIS SEASON. THE SURFACE LOW WILL BE SLOWER TO CROSS THE
AREA BUT SHOULD DO SO EARLY FRIDAY MORNING AS THE MAIN UPPER TROUGH
AXIS CONTINUES EASTWARD. WARM ADVECTION WILL TAKE PLACE AS THE
TROUGH DEPARTS WITH H85 TEMPS POTENTIALLY REACHING 0C BY FRIDAY
EVENING. THIS WILL ALLOW FOR A WARMING TREND TO COMMENCE WITH HIGHS
IN THE MID 20S TO AROUND 30 FRIDAY.

SATURDAY AND BEYOND...THE UPPER FLOW PATTERN WILL TEMPORARILY
DE-AMPLIFY INTO SATURDAY AS RIDGING...WHICH WILL HAVE BEEN QUITE
AMPLIFIED OVER THE WESTERN U.S. IN THE PRECEDING DAYS...BREAKS DOWN
AND TRANSLATES EASTWARD. THIS WILL CONTINUE THE FEED OF WARM AIR
INTO THE AREA SATURDAY WITH DRY WEATHER ALLOWING FOR A MARKED WARM
UP INTO THE LOWER TO MID 30S...WITH 40 POSSIBLE SOUTH. STRONG JET
ENERGY WILL BE DIGGING INTO THE WESTERN U.S. INTO SUNDAY HELPING
CARVE OUT ANOTHER UPPER TROUGH INTO THE MID SECTION OF THE COUNTRY.
A SURFACE LOW WILL LIKELY ACCOMPANY THIS TROUGH AND TRACK NORTH OF
THE AREA BUT COLD ADVECTION WILL SPREAD SOUTHEAST INTO THE
PLAINS/GREAT LAKES/OHIO VALLEY SUNDAY. PRECIP CHANCES LOOK LOW AT
THIS POINT BUT H85 TEMPS LOOK TO FALL BACK TO VALUES SIMILAR TO THIS
CURRENT COLD SNAP WITH HIGHS ONLY IN THE SINGLE DIGITS FAVORED FOR
MANY AREAS OF THE CWA MONDAY IF THIS PATTERN VERIFIES.

.CLIMATE...

321 PM CST

IT APPEARS THAT BOTH CHICAGO AND ROCKFORD WILL BOTH HAVE
ACCUMULATING SNOW ON THE CHRISTMAS CALENDAR DAY. THE LAST TIME
CHICAGO HAS SEEN AT LEAST ONE INCH OF SNOW ON CHRISTMAS YOU HAVE
TO GO BACK TO 2002...WHEN 2.0 INCHES WERE OBSERVED ON THE 25TH. AS
FOR ROCKFORD...ONE HAS TO GO ALL THE WAY BACK TO CHRISTMAS OF 1962
TO SEE AN INCH OR MORE! 2.1 INCHES WERE OBSERVED THAT DAY. NOW IT
IS IMPORTANT TO NOTE THAT 1996 HAD 0.10 INCH OF PRECIP WITH A HIGH
OF ONLY 5...BUT NO SNOWFALL OBSERVATION WAS TAKEN THAT DAY.

//ORD AND MDW CONCERNS...UPDATED 12Z...

* PERIOD OF MVFR CEILINGS AND LIGHT TO MODERATE SNOW THIS MORNING
  THROUGH 14Z.

//DISCUSSION...UPDATED 12Z...

ALTHOUGH LIGHT SNOW OR FLURRIES HAVE BEEN ONGOING ACROSS THE AREA
FOR MOST OF THE NIGHT...AM MONITORING SOME SNOW MOVING SOUTHWEST
OFF THE LAKE EARLY THIS MORNING. AM CONCERNED THAT THIS MIGHT BE
MORE IN THE FORM OF MODERATE TO MAYBE EVEN HEAVY SNOW AND SO HAVE
TRENDED THE TAF MORE PESSIMISTIC HERE IN THE NEAR TERM. HAVE THIS
TIMED INTO OHARE AROUND 1230Z THIS MORNING...AND SHOULD ONLY LAST
FOR A HALF HOUR AT MOST. MVFR CEILINGS WILL CONTINUE TO BE
OBSERVED...BUT WITH VIS TO POSSIBLY FALL DOWN TO AS LOW AS 1SM IN
THIS SNOW. DPA AND MDW COULD OBSERVE THIS SNOW AS WELL...BUT WITH
CONFIDENCE LOW WITH GYY. EXPECT ANY FURTHER DEVELOPMENT OVER THE
LAKE TO MOVE MORE SOUTH/SOUTHEAST...POSSIBLY MOVING OVER GYY
WITHIN THE NEXT 2-3 HOURS. ANTICIPATE SNOW TO BE OVER AFTER
THIS TIME FRAME...WITH CEILINGS IMPROVING THROUGH THE REMAINDER OF
THE MORNING. CONDITIONS SHOULD REMAIN ON THE QUIET SIDE THIS
AFTERNOON AND EVENING...WITH WEST WINDS BECOMING MORE SOUTHWEST
DURING THIS TIME. WITH INCREASING SOUTHERLY WINDS/GUSTS THIS
EVENING AND OVERNIGHT...CONFIDENCE IS HIGHER FOR LOWERING CEILINGS
TONIGHT WITH AN APPROACHING SYSTEM AND SNOW. EXPECT CONDITIONS TO
DETERIORATE AFTER MIDNIGHT TONIGHT...CONTINUING INTO EARLY
WEDNESDAY MORNING WITH MVFR CEILINGS AND IFR VIS IN SNOW LIKELY.

RODRIGUEZ

//ORD AND MDW CONFIDENCE...UPDATED 12Z...

* MEDIUM HIGH CONFIDENCE WITH MVFR CEILINGS AND SNOW/VSBYS THIS
  MORNING.

* MEDIUM HIGH CONFIDENCE WITH MVFR CEILINGS AND TIMING
  TONIGHT/WEDNESDAY MORNING.

* MEDIUM HIGH CONFIDENCE WITH VIS/LIGHT SNOW/TIMING
  TONIGHT/WEDNESDAY MORNING.

422 AM CST

AS A TROUGH OF LOW PRESSURE CONTINUES TO WEAKEN AND SHIFT EAST
OVER THE CENTRAL GREAT LAKES THIS MORNING...EXPECT THE VARYING
WINDS ACROSS THE ENTIRE LAKE TO DIMINISH INTO MIDDAY AS HIGH
PRESSURE MOVES OVERHEAD. ALTHOUGH AS SOON AS THIS DOES SO...THIS
HIGH WILL QUICKLY SHIFT TO THE EASTERN GREAT LAKES TONIGHT AS A
TROUGH OF LOW PRESSURE MOVES EAST THROUGH THE NORTHERN PLAINS INTO
THE UPPER MIDWEST. AS THIS OCCURS...EXPECT WINDS ACROSS THE ENTIRE
LAKE TO COME BACK TO MORE OF A SOUTHWEST DIRECTION THIS AFTERNOON
AND THEN A SOUTHERLY DIRECTION TONIGHT. STRONG SOUTHERLY WINDS
WILL DEVELOP WITHIN THIS TIGHT PRESSURE GRADIENT...WITH GALES TO
40 KT LIKELY OVER THE OPEN WATERS TONIGHT INTO WEDNESDAY MORNING.
WINDS IN THE NEARSHORE WILL ALSO BE OUT OF THE SOUTH AND TO 30 KT.
CONFIDENCE WITH REGARDS TO GALES IN THE NEARSHORE IS LOW AT THIS
TIME. ALTHOUGH...DID INCLUDE GALE FORCE GUST MENTIONING FOR
TONIGHT AS AT LEAST THESE GUSTS ARE POSSIBLE. WILL NEED TO
CONTINUE TO MONITOR LATER TRENDS FOR THE POSSIBILITY OF HIGHER
SPEEDS IN THE NEARSHORE TONIGHT INTO EARLY WEDNESDAY MORNING.
WINDS WILL TURN MORE WEST SOUTHWEST WHILE DIMINISHING ON
WEDNESDAY...BUT WITH SMALL CRAFT CRITERIA CONDITIONS CONTINUING
INTO WEDNESDAY NIGHT.
