AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO IL
615 AM CST SUN DEC 23 2007
.DISCUSSION...
358 AM CST
MAIN FOCUS IS WITH SHORT TERM EVOLUTION OF STRONG LOW PRESSURE
OVER UPPER MIDWEST THROUGH TONIGHT...PARTICULARLY WINDS.
RAPIDLY DEEPENING SURFACE LOW PRESSURE ANALYZED OVER NORTHEAST
ILLINOIS AT 09Z...BENEATH VIGOROUS MID LEVEL SHORT WAVE TROUGH
ROTATING NORTHWARD AROUND MAIN UPPER LOW CENTER OVER MID
MISSISSIPPI VALLEY. IMPRESSIVE -8/+9 MB ISALLOBARIC RISE/FALL
COUPLET FROM CENTRAL ILLINOIS TO WISCONSIN AIDING TIGHTENING
PRESSURE GRADIENT TO PRODUCE STRONG AND GUSTY SYNOPTIC WIND FIELD
ACROSS THE REGION...WITH WINDS ALREADY GUSTING 30 TO 40 MPH AT
MANY LOCATIONS ESPECIALLY IN STRONGEST ISALLOBARIC GRADIENT ACROSS
SOUTHERN CWA. BASED ON THESE FACTORS HAVE MOVED START TIME TO WIND
ADVISORY TO CURRENT...09Z.
FROM A PRECIPITATION PERSPECTIVE...LINE OF CONVECTIVE SHOWERS HAS
LIFTED NORTH AND EAST OF FORECAST AREA AHEAD OF OCCLUDING SURFACE
SYSTEM. COLD/OCCLUDED FRONT CURRENTLY LIFTING THROUGH NORTHEAST
CWA...WITH TEMPERATURES RAPIDLY FALLING FROM LOW 50S INTO THE 20S.
ACROSS THIS SHARP FRONTAL ZONE TO THE WEST...RADAR/SFC
OBSERVATIONS INDICATE AREA OF LIGHT SNOW. COMBINATION OF STRONGEST
DIFFERENTIAL VORTICITY ADVECTION...INTENSE LOW LEVEL FRONTOGENESIS
AND POSITION BENEATH DIVERGENT LEFT EXIT REGION OF UPPER JET
MAX...ALL LIFTING INTO WISCONSIN WITH STRONG MID LEVEL SHORT
WAVE...THUS EXPECT MAINLY LIGHT SNOW/SNOW SHOWERS TO AFFECT THE
FORECAST AREA THIS MORNING. AREAS MOST LIKELY TO SEE SOME
ACCUMULATION EARLY THIS MORNING WILL BE GENERALLY ALONG AND WEST
OF THE INTERSTATE 39 CORRIDOR...IN ASSOCIATION WITH TAIL END OF
DEFORMATION BAND OF PRECIPITATION. COULD SEE AN INCH OR TWO IN
THESE AREAS MAINLY EARLY THIS MORNING BEFORE TAPERING TO LIGHT
SNOW SHOWERS OR FLURRIES...THOUGH STRONG WINDS PROVIDE BLOWING
SNOW CONDITIONS. HAVE INDICATED STRONGLY NON-DIURNAL HOURLY
TEMPERATURES IN GRIDS WITH READINGS CONTINUING TO FALL INTO THE
TEENS AND 20S THROUGH THE DAY...STRONG WINDS WILL COMBINE TO MAKE
FOR WIND CHILLS IN THE -5 TO +5 RANGE. QUITE A BITTER AND VERY
WINDY SHIFT FROM THE MILD TEMPERATURES OF THE LAST 48 HOURS.
SECOND MID LEVEL VORTICITY CENTER WRAPS ACROSS THE REGION THIS
AFTERNOON AS UPPER LOW CONTINUES TO DEEPEN ACROSS THE NORTHERN
GREAT LAKES REGION. THIS SHOULD CONTINUE TO MAINTAIN ENOUGH
FORCING FOR OCCASIONAL SNOW SHOWERS/FLURRIES...ESPECIALLY LATER
THIS AFTERNOON/EVENING ACROSS MAINLY NORTHERN 2/3 OF FORECAST
AREA. HAVE INCLUDED UP TO A HALF INCH OF ACCUMULATION THROUGH THIS
THIS EVENING...MAINLY NORTH OF INTERSTATE 80. WHATEVER FALLS WILL
BE RATHER WIND WHIPPED HOWEVER...AND LIKELY DIFFICULT TO MEASURE.
UPPER LOW CONTINUES TO LIFT NORTHEAST AWAY FROM THE AREA AND INTO
QUEBEC ON MONDAY...WHILE ADDITIONAL WEAK SHORT WAVE ENERGY DROPS
IN ACROSS MISSISSIPPI VALLEY. WILL MAINTAIN CHANCE OF FLURRIES
THROUGH THE DAY MONDAY...BEFORE WEAK UPPER RIDGING DEVELOPS MONDAY
NIGHT. SHOULD NOTE THAT THERE ARE TIMING/PHASING DIFFERENCES
BETWEEN MODELS BY 12Z TUESDAY HOWEVER...THOUGH WITH SOME CONSENSUS
BETWEEN GFS/ECMWF AND GEM IN A SLOWER AND MORE OPEN TROUGH AS
OPPOSED TO THE MUCH FASTER NAM...AND THE SLOWER BUT DEEPER/CLOSED
UKMET. FEW CHANGES TO REMAINDER OF FORECAST. STILL APPEARS NEXT
PRECIP CHANCE WILL BE WEDNESDAY AS SURFACE COLD FRONT/UPPER TROUGH
MOVE THROUGH. LOW LEVEL THICKNESS FIELDS INDICATE PRECIPITATION TO
BE MAINLY LIGHT SNOW WITH THIS WEAK SYSTEM. LONGER RANGE MODELS
DEVELOP LARGE UPPER TROUGH OVER WESTERN CONUS THURSDAY-FRIDAY WITH
SURFACE LOW TRACK NORTHWEST OF CHICAGO SIMILAR TO CURRENT SYSTEM.
HAVE ADDED CHANCE OF RAIN/SNOW RATHER THAN JUST SNOW TO FRIDAY
FORECAST IN VICINITY OF WARM SECTOR. DIFFERENCES EXIST BETWEEN
OPERATIONAL GFS/ECMWF WITH ULTIMATE EVOLUTION OF THIS SYSTEM AND
TIMING/PHASING OF INDIVIDUAL SHORT WAVES ROTATING THROUGH THE MAIN
UPPER TROUGH. LARGE ENSEMBLE SPREAD AS WELL BY FRIDAY/SATURDAY SO
STAY TUNED.

.AVIATION...
615 AM CST
12Z TAFS...MAIN FORECAST FOCUS WILL BE ON STRONG WINDS TODAY AND
LIGHT SNOW. STRONG SURFACE LOW CONTINUES TO DEEPEN ACROSS EAST
CENTRAL WISCONSIN WITH STRONG SURFACE PRESSURE RISES ON THE ORDER OF
9 MB/3 HOURS ACROSS NORTH CENTRAL ILLINOIS. THESE STRONG PRESSURE
RISES AND STRONG COLD ADVECTION HAVE CONTRIBUTED TO GUSTS INTO THE
40 KNOT RANGE OVER THE PAST SEVERAL HOURS. INCREASING SUBSIDENCE IN
THE WAKE OF A RATHER VIGOROUS SHORT WAVE CURRENTLY MOVING THROUGH
EASTERN WISCONSIN SHOULD PROMOTE GOOD MOMENTUM TRANSFER THROUGH THE
MORNING HOURS ALLOWING FOR CONTINUED GUSTS IN THE 30 TO 35 KNOT
RANGE. STRONG SURFACE PRESSURE GRADIENT WILL BE MAINTAINED THROUGH
THE DAY AS THE SURFACE LOW CONTINUES TO DEEPEN AS IT TRACKS INTO THE
UPPER PENINSULA OF MICHIGAN TOWARD MIDDAY. THIS WILL ALLOW WEST
WINDS OF 25G35KT TO PERSIST THROUGH THE EARLY EVENING HOURS. IN
TERMS OF PRECIP...SCATTERED SNOW SHOWERS WILL PERSIST THIS
MORNING...BUT EXPECTING DECREASING TREND TO LIGHT SNOW THROUGH THE
MORNING AS SYNOPTIC SUBSIDENCE INCREASES...ALTHOUGH WILL LIKELY HAVE
OFF AN ON FLURRIES THROUGH THE AFTERNOON. AT RFD...WHERE SNOW HAS
BEEN MORE PRONOUNCED OVERNIGHT...SOME IFR VSBYS WILL PERSIST THROUGH
MID MORNING WITH LIGHT SNOW AND BLOWING SNOW.
MORE FLURRIES OR LIGHT SNOW SHOWERS ARE POSSIBLE TONIGHT AS STRONG
VORT MAX WHICH TRACKED THROUGH NORTHEAST ILLINOIS EARLY THIS MORNING
BEGINS TO WRAP AROUND UPPER LEVEL CYCLONIC CIRCULATION AND APPROACH
NORTHERN ILLINOIS AGAIN BY LATE EVENING. DID KEEP TAFS DRY TONIGHT
WITH LOW CONFIDENCE IN TIMING ANY LIGHT SNOW OR FLURRIES
TONIGHT...BUT DID MAINTAIN MID RANGE MVFR CIGS THROUGH THE NIGHT.

.MARINE...
410 AM CST
STRONG LOW PRESSURE ACROSS SOUTHEAST WISCONSIN WILL CONTINUE TO
DEEPEN AS IT TRACKS NORTHWARD...REACHING THE UPPER PENINSULA OF
MICHIGAN THIS AFTERNOON. A VERY STRONG PRESSURE RISE/FALL COUPLET IS
ACCOMPANYING THIS DEEPENING SYSTEM WHICH WILL ENHANCE SOUTHEAST
WINDS ACROSS THE NORTH HALF OF THE LAKE THIS MORNING LIKELY REACHING
GALE FORCE...AND ENHANCE THE SOUTH SOUTHWEST WINDS ACROSS THE SOUTH
HALF OF THE LAKE THIS MORNING LIKELY REACHING STORM FORCE GUSTS.
HAVE DECIDED TO KEEP STORM WARNING HEADLINES INTACT WITH SOUTHWEST
STORM FORCE WINDS EXPECTED TO AFFECT SOUTH HALF OF THE LAKE EARLY
THIS MORNING...AND THEN ACROSS THE NORTH HALF FROM MID TO LATE
MORNING. THE OCCLUDING SFC LOW WITH THIS SYSTEM WILL TRACK ACROSS
NORTHERN LAKE MICHIGAN TONIGHT WHICH SHOULD RESULT IN DIMINISHMENT
TO WIND SPEEDS ACROSS THE NORTHERN THIRD OF THE LAKE TONIGHT.
ALTHOUGH AS PREVIOUSLY MENTIONED...WILL STAY WITH THE ORIGINAL STORM
WARNING HEADLINES AT THIS TIME. LATER FORECASTS WILL LIKELY NEED TO
CONSIDER A GALE WARNING FOR THE OPEN WATERS LATE TONIGHT INTO
POSSIBLY EARLY MONDAY...WITH LINGERING GALE FORCE WINDS EXPECTED AS
THE LOW PULLS OFF TO THE EAST.
IN TERMS OF THE NEARSHORE...WILL KEEP HIGH END GALES GOING TODAY.
THERE MAY BE A PERIOD THROUGH MID MORNING FLIRTING WITH STORM FORCE
GUSTS IN ASSOCIATION WITH STRONG PRESSURE RISES BUILDING INTO
NORTHEAST ILLINOIS. SMALL CRAFT ADVISORIES WILL LIKELY BE NEEDED ON
MONDAY AS WINDS AND WAVES SLOWLY SUBSIDE.
