AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
306 PM CST SUN DEC 27 2015

.SHORT TERM...
305 PM CST

THROUGH MONDAY NIGHT...

FULL SHORT TERM AFD WILL BE OUT LATE. UPGRADING WATCH TO WINTER
STORM WARNING AND EXPANDING THE AREA SOUTHEAST A BIT. ALSO ADDING
HIGH WIND WARNING NEAR THE LAKE AND LAKE SHORE FLOOD WARNING FOR
COOK AND LAKE COUNTIES IN IL. DUE TO THE TIMING OF HIGH WINDS AND
WINTRY PRECIP NOT OVER LAPPING PARTICULARLY WELL...HAVE OPTED TO
SEPARATE WIND ADVISORY AND FREEZING RAIN HEADLINES FOR OUR
SOUTHEAST HALF OF THE CWA.

ALL HEADLINES ON THE BOTTOM OF THE AFD REFLECT WHAT WILL BE
ISSUED.

IZZI

&&

.LONG TERM...
337 AM CST

OVERNIGHT THROUGH TUESDAY...

THE FORECAST THEME FOR THE WINTER WEATHER EVENT LATE TONIGHT INTO
MONDAY CONTINUES TO BE ONE OF STRONG WINDS AND ICING IMPACTS FROM
FREEZING RAIN...WITH ALSO SOME ACCUMULATING SLEET POTENTIAL. THE
WATCH COLLABORATIVELY CONTINUES WITH ANTICIPATED CHANGES TO
ADVISORY AND/OR WARNING NEEDED LATER TODAY...AND LIKELY HEADED
TOWARD AN ADVISORY FOR THE REST OF THE CWA FOR AT LEAST MONDAY
MORNING MINOR ICING. HAVE ALSO EXPANDED THE WATCH TO INCLUDE
LASALLE AND KENDALL COUNTIES BASED ON HIGHER AMOUNTS OF FORECAST
ACCUMULATIONS DURING THE FREEZING RAIN TIME OF THIS EVENT...AND
THUS HIGHER IMPACT ICE ACCUMULATIONS BEING MORE PROBABLE. ALSO
CONCERNS FOR MINOR FLOODING FROM HEAVY TOTAL PRECIPITATION EXIST
ACROSS THE SATURATED AREA.

MODEL GUIDANCE IS IN INCREASINGLY BETTER AGREEMENT WITH THE TRACK OF
THE SYSTEM. WHILE THE GFS CONTINUES TO BE SLIGHTLY FURTHER EAST AND
COOLER...AT LEAST AT 27.00Z...WE CONTINUE TO PREFER THE FURTHER
WEST ECMWF...NAM...AND SEVERAL HIGH RESOLUTION MODELS THAT HAVE
SOLUTIONS AT LEAST INTO MONDAY. THE MAGNITUDE OF QPF HAS INCREASED
AND WPC AND LOCAL WFOS HAVE GONE WITH SLIGHTLY HIGHER QPF...WHICH
YIELDS HIGHER ICE AMOUNTS ESPECIALLY MONDAY MORNING AND EARLY
AFTERNOON. THE KEY DETAILS THAT HAVE SOME SPREAD IN GUIDANCE
REMAIN ON SPECIFIC PRECIPITATION TYPE FROM RATE OF SURFACE
TEMPERATURE WARMING AND DEPTH OF REFREEZE LAYER. BASED ON THE
STRONG EAST-NORTHEAST SURFACE WINDS AND MODEST TO HEAVY
PRECIPITATION RATES ON MONDAY...WE PREFER NULL TEMPERATURE
WARMING IN THE MORNING AND THEN A GRADUAL RISE FROM THE SOUTH IN
THE AFTERNOON THAT ACCELERATES DURING THE MID TO LATE AFTERNOON.

THE DEEP COLD CORE /-32C AT 500MB/ UPPER LEVEL CIRCULATION IS SEEN
ON WATER VAPOR IMAGERY OVER THE RIO GRANDE VALLEY EARLY THIS MORNING
AND WILL EJECT AS A NEGATIVELY TILTED CIRCULATION TONIGHT AND
MONDAY...REACHING THE UPPER GREAT LAKES BY EARLY TUESDAY MORNING.
THIS WILL RIDE WITHIN AND STEER BACK NORTHWARD AN IMPRESSIVELY
STOUT SUBTROPICAL PLUME OF MOISTURE. IT WILL ALSO ASSIST AN
ALREADY TIGHT ELEVATED BAROCLINIC ZONE DOWNSTATE ILLINOIS AND
INDIANA NORTHWARD LATE TONIGHT AS WELL AS RE-ORIENT THIS FORCING
FOCUS MORE EAST-TO-WEST. THE DEVELOPING PRECIPITATION LATE THIS
EVENING AND OVERNIGHT SHOULD FIT THIS ORIENTATION OF THE ELEVATED
WARM FRONT AND INCH ITS WAY NORTHWARD OVERNIGHT AS ELEVATED MOIST
ADVECTION EXPANDS IN DEPTH. TEMPERATURES LOOK TO MORE THAN LIKELY
BE JUST ABOVE FREEZING SOUTH OF I-80 WHEN PRECIPITATION
STARTS...HOWEVER A COUPLE DEGREE DROP SHOULD OCCUR THROUGH WET
BULBING. SO MAINTAIN THE CHANCE FOR FREEZING RAIN ALL THE WAY DOWN
TO THE SOUTHERN FORECAST AREA. FOR THESE SOUTHERN
AREAS...BASICALLY SOUTH OF THE I-80 CORRIDOR...EVEN MONDAY MORNING
SEEMS LIKE IT WOULD NOT HAVE ANY WARMING...SO HAVE MAINTAINED THE
CHANCE FOR FREEZING RAIN THROUGH THE ENTIRE MORNING ACCOUNTING
FOR SOME UNCERTAINTY IN SPECIFIC TEMPERATURE FORECASTS.

FURTHER NORTH...FOR BASICALLY THE INTERSTATE 80 CORRIDOR AND
NORTHWARD...PRECIPITATION LOOKS TO ONSET IN THE PRE-DAWN TO DAYBREAK
TIME...AND MAYBE A COUPLE HOURS AFTER SUNRISE NEAR THE WISCONSIN
BORDER. PRECIPITATION INTENSITY MAY ALSO BE LIGHT FOR A BRIEF WHILE
AT ONSET BUT SHOULD INCREASE FAST MID TO LATE MORNING. SURFACE
TEMPERATURES HERE STILL LOOK TO BE MORE OF THE 29-32 VARIETY AT
ONSET...OUTSIDE OF NEAR THE LAKE AND THE HEART OF THE CHICAGO
METRO...AND MAYBE DROPPING A DEGREE OR TWO WITH THE FREEZING
RAIN/SLEET. THE PROJECTED DEPTH OF THE FREEZING LAYER AT ROCKFORD
IS BETWEEN 3000 TO 5000 FT THROUGH THE MORNING MONDAY BASED ON THE
NAM AND GFS RESPECTIVELY. EVEN THAT NAM DEPTH OFFERS SLEET...OR
MAYBE EVEN SNOW POTENTIAL FOR SEVERAL HOURS AT FIRST. THAT COULD
CHANGE THE MAGNITUDE OF IMPACTS SOME...BUT STILL THINK A
TRANSITION TO MORE OF A FREEZING RAIN WILL OCCUR AS THE MORNING
WEARS ON INTO EARLY AFTERNOON...WITH SEVERAL HOURS BEFORE THE
TRANSITION TO RAIN. THE AREA SOUTH OF ROCKFORD...INCLUDING
DIXON...DEKALB...OTTAWA...MENDOTA...AND ESPECIALLY THE WESTERN
METRO LOOK TO HAVE THE HIGHEST DURATION OF FREEZING RAIN AND THUS
THE HIGHER ICE ACCUMULATIONS THERE. AROUND ONE QUARTER OF AN INCH
IS CURRENTLY FORECAST BUT WITH A FAIRLY LARGE SPREAD POSSIBLE
SINCE WE HAVE QUITE A BIT MORE ACTUAL RAINFALL FORECAST. THE ICE-
TO-LIQUID RATIO IS ALWAYS A FORECAST CHALLENGE AND VARIES BY
SEVERAL ELEMENTS BASED ON CLIMATOLOGY /SOME IN FAVOR DURING THIS
EVENT AND SOME NOT/...AND ICE ACCRETION VARIES SIGNIFICANTLY FROM
FLAT SURFACES TO ELEVATED RADIAL ONES SUCH AS WIRES. THE
SIGNIFICANT EASTERLY WINDS THROUGHOUT MONDAY TIP THE SCALE A
LITTLE BIT TO STRESS IMPACTS OF THE ICING INCLUDING POTENTIAL
POWER OUTAGES.

REGARDING THE WINDS...THE RAPIDLY INCREASING PRESSURE GRADIENT AND
NEAR RECORD ANOMALOUS LOW-LEVEL EASTERLY FLOW STRENGTH...SUPPORTS
AT LEAST NEAR WIND ADVISORY CRITERIA FOR MUCH OF THE CWA WITH
GUSTS TO 40 TO 45 MPH. BOUNDARY LAYER MIXING SUPPORTS THIS USING A
NAM AND GFS MEAN. NEAR LAKE MICHIGAN GUSTS OF 50 TO 55 MPH ARE
POSSIBLE ESPECIALLY DURING THE AFTERNOON AND EVENING. THESE
EASTERLY WINDS TAPPING INTO ALREADY HIGH WAVES FROM TODAY AND
LAKE LEVELS ON THE SOUTHERN PART OF THE LAKE MAY LEAD TO LAKESHORE
FLOODING ALONG THE NORTHEAST ILLINOIS SHORE...INCLUDING SOME
FAVORED IMMEDIATE AREAS ALONG THE CHICAGO SHORE.

THE SYSTEM DRY SLOT LOOKS TO MOVE OVER THE AREA MID TO LATE MONDAY
EVENING TRANSITIONING PRECIP TO MORE LIGHT RAIN AND/OR DRIZZLE.
TEMPERATURES LOOK CONFIDENTLY TO BE ABOVE FREEZING THROUGH THE
ENTIRE AREA BY EARLY EVENING /ONLY EXCEPTION WOULD SEEM TO BE NEAR
ROCKFORD/...HOWEVER ITS CERTAINLY POSSIBLE SOME IMPACTS REMAIN
GIVEN CONTINUED GUSTY WINDS IN THE EARLY TO MID EVENING. THERE IS
SOME CHANCE AS THE COLUMN COOLS TO SEE A LITTLE BIT OF LIGHT SNOW
IN THE WEST DURING THE NIGHT AND MAYBE TUESDAY MORNING...BUT ICE
PRESENCE IN THE CLOUD LOOKS MARGINAL. ANY PRECIPITATION ON TUESDAY
LOOKS TO BE LIGHT.

MTF

WEDNESDAY THROUGH SATURDAY...

A COLDER WEATHER PATTERN WILL EVOLVE FOR THE SECOND HALF OF THE
COMING WEEK...AS HEIGHTS FALL ACROSS THE EASTERN CONUS IN RESPONSE
TO ANOTHER UPPER LOW PROPAGATING NORTHEAST FROM THE PLAINS TO THE
ST LAWRENCE RIVER VALLEY WEDNESDAY-THURSDAY. MUCH DRIER AIR
WRAPPING AROUND THE DEPARTING/WEAKENING SURFACE LOW AT THE
BEGINNING OF THE PERIOD WILL NOT SUPPORT MUCH IN THE WAY OF
SUBSTANTIAL PRECIPITATION DURING THE PERIOD...THOUGH THE STRONG
MID-LEVEL SHORT WAVE AND SECONDARY SURFACE TROUGH/COLD FRONT WHICH
MOVE THROUGH THE AREA ON WEDNESDAY DOES LOOK TO PROVIDE MORE THAN
ADEQUATE FORCING FOR PRODUCING SOME LIGHT PRECIP. FORECAST
SOUNDINGS DEPICT A COLUMN COLD ENOUGH FOR SNOW...PROVIDED BY A
PERIOD OF MID-LEVEL MOISTURE/ICE NUCLEI WITH THE SHORT WAVE.
GUIDANCE QPF GENERALLY ONLY A FEW HUNDREDTHS OF AN
INCH...SUGGESTING ONLY MINOR ACCUMULATION IF ANY...AND THAT
PRIMARILY ORIENTED ACROSS NORTH CENTRAL IL.

COLDER WEATHER THEN SETS IN FOR THE REMAINDER OF THE
PERIOD...WITH WEST-NORTHWEST LOW LEVEL FLOW. FORECAST THERMAL
FIELDS SUPPORT DAYTIME TEMPS IN THE MID-UPPER 20S...AND OVERNIGHT
MINS IN THE TEENS TO LOW 20S. COLDER AIR WILL LIKELY PRODUCE SOME
LIGHT LAKE EFFECT SNOW SHOWERS...THOUGH THE WEST-NORTHWEST FLOW
SHOULD KEEP THIS ACTIVITY MAINLY OVER THE LAKE AND EAST OF THE
CWA.

.HYDROLOGY...
104 PM CST

A POWERFUL STORM SYSTEM WILL DRAW COPIOUS AMOUNTS OF MOISTURE
NORTHWARD ON MONDAY. SOME OF THE PRECIPITATION WILL FALL AS SLEET
AND FREEZING RAIN. TOTAL FORECAST LIQUID EQUIVALENT AMOUNTS ARE IN
THE 1 TO 1.5 INCH RANGE ACROSS NORTHERN AND CENTRAL ILLINOIS AND
NORTHWEST INDIANA. WITH SUCH ANOMALOUSLY HIGH MOISTURE
LEVELS...LOCALLY HIGHER TOTALS ARE PROBABLE. 24-HOUR RAIN AMOUNTS
FROM SATURDAY INTO SUNDAY MORNING WERE UP TO 2-3 INCHES SOUTH OF
THE KANKAKEE RIVER. THIS RAIN HAS ALREADY RESULTED IN RISES ON
RIVERS AND STREAMS IN THIS AREA. THE ADDITIONAL RAIN ON MONDAY
WILL EXACERBATE AND PROLONG ONGOING RISES. FOR AREAS FARTHER
NORTH...RIVER AND STREAM LEVELS ARE ALREADY RUNNING ABOVE
NORMAL...AND THE HEAVY FORECAST PRECIPITATION WILL RESULT IN
RENEWED RISES.

1040+ MB HIGH PRESSURE SPREADING IN FROM THE NORTHERN PLAINS
ALREADY RESULTING IN NORTHERLY WINDS UP TO 30 KT ON THE LAKE TODAY
WILL SLIDE EAST TO JUST NORTH OF THE GREAT LAKES ON MONDAY. THE
EXTREMELY TIGHT PRESSURE GRADIENT BETWEEN THE APPROACHING LOW
