AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
554 AM CST WED DEC 26 2012

.DISCUSSION...
339 AM CST

MUCH LIKE A BROKEN RECORD (OR A CORRUPT MP3 FOR TODAY'S
GENERATION)...THE FORECAST CONCERNS AGAIN THIS MORNING ARE LAKE
EFFECT POTENTIAL...SNOW THREAT IN SE CWA TODAY...AND THEN
FRIDAY'S SYSTEM AND ASSOCIATED SNOW CHANCES.

CONVERGENCE ZONE FROM CHRISTMAS EVE INTO CHRISTMAS DAY HAS SHIFTED
WELL NORTH OF THE CWA AS LOW LEVEL FLOW IS RAMPING UP QUICKLY WITH
TIGHTENING GRADIENT ON NORTH SIDE OF THE GORGEOUS CYCLONE DOWN IN
THE TN VALLEY. DEFORMATION BAND ON NW FLANKS OF THE SYSTEM HAS BEEN
LIGHTING UP EARLY THIS MORNING WITH CLOUD TOPS COOLING TO AROUND
-60C WITH EVEN SOME EMBEDDED THUNDERSNOW/SLEET. EXPECT THIS DEFO
BAND TO START TO WEAKEN THIS MORNING AS SECONDARY CYCLOGENESIS
OCCURS ALONG THE EAST COAST AND FRONTOGENESIS WEAKENS WITHIN THE
TROWAL. NORTHERN EDGE OF THE PRECIP STRUGGLING AGAINST THE DRY AIR
ABOVE 850MB OVER THE REGION THAT WAS SAMPLED NICELY ON THE 00Z
RAOBS. THAT DRY AIR SHOULD RESULT IN A SOMEWHAT SHARP CUT OFF ON THE
NORTHWEST FLANKS OF THE DEFO BAND THOUGH IT STILL LOOKS LIKE OUR SE
FEW COUNTIES WILL SEE SOME MEASURABLE SNOW TODAY...POSSIBLY EVEN A
COUPLE INCHES OVER BENTON COUNTY BEFORE THE SYSTEM BEGINS TO PULL
AWAY LATE THIS AFTERNOON.

HIGH-RES MODELS ARE NOT EXCITED ABOUT THE LAKE EFFECT POTENTIAL THIS
AFTERNOON...WHICH IS UNUSUAL SINCE THEY ALWAYS SEEM TO WANT TO BREAK
OUT LAKE EFFECT. DESPITE THE LESS THAN STELLAR ENDORSEMENT FROM THE
MESOSCALE MODELS HAVE OPTED TO HANG ONTO CHANCES FOR LAKE EFFECT
SNOW THIS AFTERNOON INTO THIS EVENING AS PERSISTENT LAKE EFFECT
STRATOCUMULUS POTENTIALLY GETS SEEDED BY THE MID LEVEL MOISTURE
BEING FLUNG AROUND THE NORTHWEST FLANKS OF THE OHIO/TENNESSEE VALLEY
STORM. WHILE LAKE EFFECT SURPRISES CAN NEVER BE RULED OUT...OVERALL
SET UP REALLY DOESN'T FAVOR MUCH IF ANY ACCUMULATION TODAY INTO
TONIGHT. STRONG GRADIENT FLOW WHICH WILL HELP PRODUCE WIND GUSTS TO
40 MPH OR POSSIBLY A LITTLE GREATER ALONG THE LAKE WILL ALSO LIKELY
PREVENT ANY WELL DEVELOPED LAND BREEZE CONVERGENCE ZONES FROM
DEVELOPING AND FOCUSING LAKE EFFECT.

WHILE THE STORM WILL MOVE OUT OF THE REGION LATER TODAY INTO TONIGHT
AM CONCERNED THAT STRATUS DECK COULD LINGER...PARTICULARLY NEAR THE
LAKE. WESTERN CWA STANDS THE BEST CHANCES OF SEEING CLOUDS BREAK UP
OR EVEN CLEAR OUT LATER TONIGHT/THURSDAY...WHICH COULD ALSO ALLOW
TEMPS TO GET COLDER TONIGHT THERE.

VIGOROUS TROUGH APPROACHING THE WEST COAST THIS MORNING IS PROGGED
TO MOVE RATHER QUICKLY EASTWARD SHEARING OUT SOMEWHAT AND
DEAMPLIFYING AS IT DOES. WHILE THE SYSTEM IS STILL OFFSHORE WATER
VAPOR IMAGERY WOULD SUGGEST THAT BOTH THE GFS AND ECMWF INITIALIZED
THIS SYSTEM FAIRLY WELL AND THE MODEL DIFFERENCES ARE FAIRLY SMALL
AS THE SYSTEM MOVES INTO THE REGION FRIDAY. BOTH WOULD SUGGEST A
BAND OF LIGHT LIKELY TO ACCOMPANY THE SYSTEM WITH THE BEST CHANCES
CURRENTLY LOOKING TO BE NEAR AND ESPECIALLY NORTH OF THE CHEDDAR
CURTAIN. SURFACE TEMPERATURES ARE PROGGED TO BE NEAR OR A HAIR ABOVE
FREEZING FRIDAY SO ANY SNOW THAT DOES FALL MAY STRUGGLE A BIT TO
ACCUMULATE...THOUGH AS YOU GET CLOSER TO THE WI BORDER FORECAST
SOUNDINGS DO SHOW A MORE FAVORABLE THERMAL PROFILE ALOFT TO SUPPORT
AN ACCUMULATING SNOWFALL. HAVE BUMPED UP POPS TO LIKELY NORTHERN CWA
TAPERING OFF RATHER ABRUPTLY TO SLIGHT CHANCE SOUTH. ANY SHIFT IN
THE TRACK COULD OFFER UP A BETTER CHANCE OF AN INCH OR TWO OF SNOW
FARTHER SOUTH INTO THE CWA...BUT AS IT STANDS NOW THAT POTENTIAL
LOOKS BETTER NEAR THE BORDER.

CLOUDINESS LIKELY TO HANG AROUND FRIDAY NIGHT AND POTENTIALLY INTO
AT LEAST PART OF THE WEEKEND. RESPECTABLE LITTLE PUSH OF COLD AIR
PROGGED TO ARRIVE SATURDAY...THOUGH TEMPS MAY START OFF SAT FAIRLY
MILD IF OVC HANGS AROUND AS EXPECTED FRI NIGHT. GENERALLY DIDNT
STRAY MUCH FROM GUIDANCE IN THE EXTENDED WITH CONTINUED GENERALLY
NEAR AVERAGE TEMPERATURES AND VERY LITTLE THREAT FOR ANY PRECIP
AFTER FRIDAY/FRIDAY NIGHT SYSTEM MOVES BY.

.AVIATION...

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

* MVFR TEMPO VFR CIGS INTO MID MORNING THEN PREVAILING MVFR
  PERSISTING INTO THE EVENING.

* POTENTIAL FOR NW EDGE OF SYNOPTIC SCALE -SN SHIELD SPREADING
  OVER FAR NW IN AND EXTREME NE IL MIDDAY THROUGH AFTERNOON.

* POTENTIAL FOR LAKE EFFECT/LAKE ENHANCED SHSN DURING AFTERNOON.

* NE WIND INCREASING WITH GUSTS TO AROUND 30KT BY MID MORNING...
  GRADUALLY BACKING TO NNE AND N AND DECREASING LATE AFTERNOON AND
  TONIGHT.

TRS

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

THE COMBINATION OF A DEEPENING STORM SYSTEM CURRENTLY ON THE
CENTRAL KY-TN BORDER MOVING NE TO WV TODAY SPREADING THE NW EDGE
OF ITS PRECIP SHIELD TO FAR NW IN AND EXTREME NE IL DURING THE
MORNING...ALONG WITH AN INCREASING AND GRADUALLY BACKING LOW
LEVEL WIND FIELD ACROSS THE AREA WILL BRING A SOME -SN TO THE CHI
TERMINALS WITH THE POTENTIAL OF SOMEWHAT ENHANCED SNOWFALL
DEPENDING IF DECENT LAKE EFFECT CAN REGENERATE AND HAPPEN TO PASS
OVER THE TERMINALS.

BASED ON LATEST MODEL OUTPUT APPEARS THAT THE LIGHT SYNOPTIC SNOW
WILL REACH MDW MIDDAY AND POSSIBLY SPREAD AS FAR NW AS ORD DURING
THE EARLY AFTERNOON. WITH THE STORM SYSTEM CONTINUING ENE ACROSS
WV AND VA DURING THE LATE AFTERNOON AND EVENING THE BACK EDGE OF
THE PRECIPITATION WILL BE PULLING AWAY FROM THE LOCAL AREA THOUGH
ACCOMPANYING BACKING OF LOW LEVEL FLOW WILL ENCOURAGE A SINGLE
LAKE EFFECT BAND TO DEVELOP ALONG THE NORTHERN IL AND INTO CENTRAL
AND SOUTHERN COOK COUNTY AND THEN SHIFT FURTHER E AND CROSSING THE
FAR NW IN SHORE.

COULD BE SOME PERIODS OF IFR VSBY IF INTENSE ENOUGH LAKE EFFECT
CELLS MOVE DIRECTLY OVER AN AIRFIELD BUT NOT CONFIDENT IN
OCCURRENCE AND WENT RELATIVELY CONSERVATIVE WITH LENGTH OF TIME
OF IFR CONDITIONS.

N EDGE OF RADAR RETURNS FROM SOUTHERN STORM HAVE CREPT A BIT
FURTHER NORTHWARD LAST FEW HOURS TO WITHIN 55-65NM OF MDW AND ORD
AND HAVE SHOWN SOME INCREASE IN REFLECTIVITY VALUES BUT MID LEVELS
STILL TOO DRY FOR ANY PRECIP TO REACH THE SURFACE THAT FAR NORTH.
CLOSEST REPORTS OF PRECIP IN METARS ARE FROM E CENTRAL IL
NORTHEASTWARD TO E CENTRAL IN.

CEILINGS HAVE BEEN FLUCTUATING BETWEEN END MVFR AND LOW END VFR
DURING THE PREDAWN HOURS. THIS IS LIKELY A RESULT OF ADVECTION OF
SOMEWHAT DRIER LOW LEVEL AIR ACROSS SOUTHERN LAKE MI ON
INCREASING NE TO ENE LOW LEVEL FLOW FROM LOWER MI WHERE DEW
POINTS HAVE AND CONTINUE TO BE IN THE UPPER TEENS AND LOWER 20S.

THE MID LAKE CONVERGENCE ON CENTRAL LAKE MI THAT WAS SEEN IN THE
SURFACE WIND FIELD DURING THE EARLY A.M. HOURS HAS NOW BECOME
OVERWHELMED BY THE INCREASING CYCLONIC FLOW ASSOCIATED WITH THE
STORM SYSTEM WHO/S SURFACE LOW IS CURRENTLY LOCATED ON THE CENTRAL
KY-TN BORDER. THIS BROAD NE FLOW ACROSS THE S END OF THE LAKE HAS
RECENTLY RESULTED IN THE GENERATION OF LIGHT LAKE EFFECT SNOW
MOVING ASHORE ACROSS THE CHI AREA INCLUDING MDW AND ORD.

236 AM CST

EARLY THIS MORNING A HIGH PRESSURE RIDGE EXTENDED FROM THE
SOUTHERN CANADIAN PRAIRIES AND THE NORTHERN PLAINS EASTWARD
ACROSS ONTARIO AND QUEBEC. A FAIRLY DEEP LOW WAS ON THE NORTHERN
MS-AL BORDER.

THE EASTERN PORTION OF THE RIDGE LIFTS NORTHWARD AS THE LOW MOVES
NE ACROSS THE TN VALLEY TO THE CENTRAL APPALACHIANS BEFORE
STARTING TO REFORM NEAR THE CHESAPEAKE BAY LATE IN THE DAY. THE
PRESSURE GRADIENT AND INDUCED INCREASE IN WINDS WILL CONTINUE
ACROSS THE SOUTHERN AND EASTERN GREAT LAKES TODAY BETWEEN THE
RIDGE JUST N OF THE GREAT LAKES AND THE LOW MOVING ACROSS THE TN
VALLEY AND CENTRAL APPALACHIANS. WINDS ON SOUTHERN LAKE MICHIGAN
WILL BE UNDER THE TIGHTEST PRESSURE GRADIENT WITH NE WINDS
INCREASING TO 30 KTS LATER TODAY AND PERSISTING INTO THIS EVENING
BEFORE STARTING TO GRADUALLY DIMINISH A BIT AND BECOME N OVERNIGHT
AS THE LOW MOVES UP THE MID ATLANTIC COAST TO THE JERSEY SHORE AND
A RIDGE OF HIGH PRESSURE BUILDS SOUTHWARD ACROSS THE MS VALLEY
TONIGHT. SOME OCCASIONAL GUSTS TO LOW END GALE FORCE ARE EXPECTED
ON SOUTHERN LAKE MI BUT DO NOT FEEL THEY WILL BE WIDESPREAD NOR
PERSISTENT ENOUGH TO WARRANT A GALE WARNING FOR TODAY THOUGH WILL
HAVE TO CONTINUED TO BE MONITORED INCREASE THE INCREASE IN SPEEDS
IS A BIT MORE THAN CURRENTLY EXPECTED.

AS THE LOW MOVES FURTHER AWAY TO OFF THE COAST OF MAINE THU AND
THE UPSTREAM RIDGE GRADUALLY MOVING E TO THE UPPER MIDWEST...
WESTERN GREAT LAKES AND LOWER OHIO VALLEY WINDS OVER LAKE MI WILL
CONTINUE TO SLACKEN TO GENERALLY 10-15KT BY THU NIGHT

CONTINUED NE WINDS DOWN THE LAKE HAVE MAINTAINED FAIRY TALL WAVES
ALONG THE IL AND IN SHORES AND WITH INCREASING VELOCITIES THEY ARE
EXPECTED TO BUILD EVEN HIGHER LATER TODAY. GIVEN WINDS FORECAST TO
UP TO 30 KT BY AFTERNOON AND A CONTINUED BUILDING OF WAVE HEIGHTS
THE SMALL CRAFT ADVISORY ALREADY IN EFFECT FOR ALL OF THE IL AND
IN NEARSHORE WATERS WILL DEFINITELY BE RETAINED.
