THE NATIONAL WEATHER SERVICE IN CHICAGO HAS ISSUED A GALE WATCH...
WHICH IS IN EFFECT FROM MONDAY MORNING THROUGH MONDAY EVENING. 

* SUSTAINED GALE FORCE WINDS OR FREQUENT GALE FORCE GUSTS ARE 
  POSSIBLE FROM MONDAY MORNING THROUGH MONDAY EVENING.

* DURING THE GALE WATCH...THE STRONGEST WINDS WILL BE UP TO 35 
  KT FROM THE SOUTHWEST. THE HIGHEST SIGNIFICANT WAVES WILL BE 
  UP TO 8 FT. THERE WILL BE OCCASIONAL WAVES UP TO 12 FT.

THE DENSE FOG ADVISORY IS NOW IN EFFECT UNTIL 10 PM CST THIS
EVENING. 

* EXPECT DENSE FOG WITH VISIBILITIES OF ONE QUARTER OF A MILE OR 
  LESS UNTIL 10 PM CST THIS EVENING.

THE SMALL CRAFT ADVISORY IS NOW IN EFFECT UNTIL 6 AM CST MONDAY. 

* EXPECT HAZARDOUS CONDITIONS FOR SMALL CRAFT UNTIL 6 AM CST 
  MONDAY.

* DURING THE SMALL CRAFT ADVISORY...THE STRONGEST WINDS WILL BE 
  UP TO 30 KT FROM THE SOUTHEAST. THE HIGHEST SIGNIFICANT WAVES 
  WILL BE UP TO 8 FT. THERE WILL BE OCCASIONAL WAVES UP TO 12 FT.

REFER TO THE LATEST MARINE FORECASTS FOR MORE DETAILED
INFORMATION.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A DENSE FOG ADVISORY MEANS VISIBILITIES WILL FREQUENTLY BE
REDUCED TO LESS THAN ONE QUARTER MILE. INEXPERIENCED MARINERS...
ESPECIALLY THOSE OPERATING SMALLER VESSELS SHOULD AVOID
NAVIGATING IN THESE CONDITIONS. 

A SMALL CRAFT ADVISORY MEANS THAT WINDS OF 22 TO 33 KNOTS AND/OR
WAVES GREATER THAN 4 FT WILL PRODUCE HAZARDOUS WAVE CONDITIONS
FOR SMALL CRAFT. INEXPERIENCED MARINERS...ESPECIALLY THOSE
OPERATING SMALLER VESSELS SHOULD AVOID NAVIGATING IN THESE
CONDITIONS.

A GALE WATCH IS ISSUED WHEN THE RISK OF GALE FORCE WINDS OF 34 TO
47 KNOTS HAS SIGNIFICANTLY INCREASED...BUT THE SPECIFIC TIMING
AND/OR LOCATION IS STILL UNCERTAIN. IT IS INTENDED TO PROVIDE
ADDITIONAL LEAD TIME FOR MARINERS WHO MAY WISH TO CONSIDER
ALTERING THEIR PLANS.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
256 PM CST SAT JAN 21 2012

.DISCUSSION...
252 PM CST

COMPLEX FORECAST ON TAP AS REGION IS LINING UP FOR STRONG LOW
PRESSURE SYSTEM TO MOVE THROUGH LATE THIS WEEKEND INTO MONDAY
BRINGING A MIXED BATCH OF PRECIPITATION.

REST OF TODAY INTO TONIGHT...THIN STRATUS DECK OVER PORTIONS OF THE
CWA EXPECTED TO CONTINUE TO PIVOT TO THE NORTH WITH CLEARING/DRY AIR
MOVING IN BEHIND...AT LEAST TEMPORARILY BEFORE WE BEGIN TO CLOUD
UP AGAIN FROM WEST AS ISENTROPIC ASCENT HELPS TO RESATURATE LOW
LEVELS. TIMING THIS CLEARING WILL BE CRITICAL FOR TEMPERATURES
OVERNIGHT AS TRANSIENT HIGH PRESSURE...LIGHT SURFACE WINDS AT LEAST
EARLY TONIGHT...AND FRESH SNOWPACK SHOULD ALL ALLOW FOR VERY QUICK
AND EFFICIENT COOLING EARLY IN THE OVERNIGHT PERIOD. WARM ADVECTION
THEN TAKES HOLD AND ALONG WITH THE INCREASING CLOUD COVER...DO
EXPECT TEMPERATURES TO BEGIN TO INCREASE LATER IN THE OVERNIGHT
PERIOD AND PREDAWN HOURS.

POTENT SHORTWAVE DIGGING ACROSS THE SOUTHWEST CONUS THIS AFTERNOON
AS SEEN ON WATER VAPOR IMAGERY WILL QUICKLY LIFT NORTHEAST ACROSS
THE PLAINS DURING THE DAY SUNDAY...REACHING THE MID MISSISSIPPI
VALLEY BY LATE SUNDAY EVENING AND TAKING ON NEGATIVE TILT. SURFACE
LOW WILL DEEPEN IN RESPONSE WITH STRONG LOW LEVEL JET OF 50+ KT
DEVELOPING OUT AHEAD OF THE LOW. BROAD ISENTROPIC ASCENT
OVERSPREADING THE REGION WILL ACT TO SATURATE LOWER ATMOSPHERE WITH
A CONSISTENT RUN-TO-RUN SIGNAL OF DRIZZLE SETTING UP ACROSS THE
REGION. MAIN CONCERN DURING THE LATE MORNING AND EARLY AFTERNOON
PERIOD SUNDAY WILL BE THE POTENTIAL FOR A WINDOW OF DRIZZLE WITH
SURFACE TEMPERATURES STILL SUB-FREEZING. OF COURSE THIS WILL BE
DEPENDENT ON HOW MUCH TEMPS TANK EARLY TONIGHT...AND HOW QUICKLY WE
WARM AS WARM ADVECTION SETS UP...AND CONFIDENCE ON THE DETAILS AT
THIS POINT IS NOT HIGH. WILL NOT BE ISSUING ANY TYPE OF ADVISORIES
AT THIS POINT...BUT MAY NEED TO OVERNIGHT AS DETAILS BECOME MORE
APPARENT.

SUNDAY NIGHT...AS LOW BEGINS TO TRAVERSE ACROSS THE AREA...MODELS
INDICATE MODEST CAPE TRANSPORTED NORTHWARD ON NOSE OF AFOREMENTIONED
JET...WITH VERY STRONG HEIGHT FALLS ALOFT AS MID LEVEL SHORTWAVE
BEGINS TO TAKE ON NEGATIVE TILT AND LEFT ENTRANCE OF 100+ KT UPPER
LEVEL JET SUPPORTS BROAD SYNOPTIC SCALE LIFT ACROSS THE AREA.
MAINTAINED THE CHANCE FOR THUNDERSTORMS...PARTICULARLY ACROSS AREAS
EAST OF THE I-55 CORRIDOR. FURTHER COMPLICATING THE SITUATION WILL
BE POTENTIALLY 40+ DEGREE DEWPOINTS TRYING TO PUSH NORTH INTO THE
CWA ON TOP OF THE RECENT SNOWFALL. THIS COULD BE IDEAL SITUATION FOR
DENSE ADVECTION FOG SETTING UP ACROSS PORTIONS OF THE CWA UNTIL THE
SNOWFALL IS ABLE TO MELT OFF...BUT GUIDANCE HAS A LARGE SPREAD ON
HOW WARM THE DEWPOINTS WILL BE...WITH SOME MODELS SUGGESTING LOW
30S...WHILE OTHERS PUSH 50S INTO THE FAR SOUTH CWA. SHOULD WE GET
THE WARMER DEWPOINTS...EXPECT A RAPID MELT WHICH COMBINED WITH
ADDITIONAL QPF...POSSIBLY LOCALLY HEAVY IF WE DO SEE CONVECTIVE
ELEMENTS...WE WILL NEED TO CLOSELY MONITOR LOCAL RIVERS AND STREAMS
FOR RISES. WITH THE RECENT SNOWFALL BEING RELATIVELY FLUFFY...SWE
VALUES FOR EXISTING SNOWPACK ARE NOT PARTICULARLY HIGH AND SO FOR
NOW NOT OVERLY CONCERNED ABOUT THE FLOODING THREAT SUNDAY NIGHT INTO
MONDAY.

NEXT WEEK...COLD FRONT SWEEPS ACROSS THE REGION EARLY MONDAY MORNING
WITH COLD AIR QUICKLY TANKING AND WOULD EXPECT A QUICK TRANSITION
FROM RAIN OVER TO SNOW. MAY SEE SOME LIGHT ACCUMULATIONS AS
DEFORMATION ZONE MOVES THROUGH...BUT NOTHING SIGNIFICANT AT THIS
TIME. ZONAL FLOW WILL DOMINATE THE PATTERN THROUGH MOST OF NEXT WEEK
WITH LOW AMPLITUDE FAST MOVING DISTURBANCES BRINGING PERIODIC
CHANCES FOR PRECIPITATION. DID NOT STRAY MUCH FROM MODEL CONSENSUS
FOR THE EXTENDED FORECAST. BMD

&&

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 21Z...

* LAKE GENERATED FLURRIES AND 015-025 CIGS THROUGH 00Z.

* VARIABLE WIND DIRECTION THROUGH EARLY EVENING.

* INCREASING SOUTHEAST WINDS LATE TONIGHT BECOMING GUSTY ON SUNDAY.

* RETURN OF SUB 2000 FT CIGS POTENTIALLY AS EARLY AS LATE
  TONIGHT...WITH IFR CONDITIONS BECOMING LIKELY LATER SUNDAY.

* SMALL CHANCE FOR FREEZING DRIZZLE AFTER THE ARRIVAL OF THE
  CLOUDS ON SUNDAY.

//DISCUSSION...UPDATED 18Z...

WHILE HIGH PRESSURE REMAINS OVER THE AREA...A LAKE EFFECT SNOW
SHOWER BAND HAS BEEN FUNNELING INTO CHICAGO. THIS HAS SHOWN SIGNS
ON TERMINAL DOPPLER RADAR LOOPS TO WEAKEN AND BE SHIFTING
NORTHWEST. SO THE SNOW AND ASSOCIATED SUB 2000 FT CIGS SHOULD
QUICKLY DIMINISH AT MDW AND JUST SKIRT ORD. JUST A DUSTING FROM
18Z TO 20Z IS EXPECTED. AS THE LOW-LEVEL WIND CONVERGENCE THAT
CAUSED THE DEVELOPMENT AND PLACEMENT OF THE BAND CONTINUES TO
WEAKEN...ANTICIPATE THAT ORD AND MDW WILL REMAIN IN A WIND LULL
WITH VARIABLE AND AT TIMES CALM WINDS. DURING THIS EVENING AN EAST
TO SOUTHEAST WIND COMPONENT SHOULD DEVELOP. THIS WILL INCREASE
INTO SUNDAY WITH GUSTS POSSIBLE BY DAYBREAK. LOW-LEVEL MOISTURE
SHOULD RETURN QUICKLY LATE TONIGHT INTO SUNDAY FAVORING LOW CLOUD
DEVELOPMENT. HOW SOON ACTUAL CLOUDS WILL DEVELOP IS A LITTLE
UNCERTAIN...AND BECAUSE OF THAT THE POTENTIAL FOR DRIZZLE IS
SOMEWHAT UNCERTAIN...ESPECIALLY EARLIER ON. IF DRIZZLE WERE TO
DEVELOP EARLY ENOUGH IT COULD BE FREEZING DRIZZLE. CLOUDS SHOULD
LOWER INTO THE LATER AFTERNOON AND EVENING. ANOTHER CONCERN FOR
SUNDAY NIGHT IS LOW-LEVEL WIND SHEAR...AS 45 TO 60 KT SOUTHERLY
FLOW DEVELOPS IN THE 1500 TO 3000 FT LAYER.

//ORD AND MDW CONFIDENCE...UPDATED 21Z...

* HIGH CONFIDENCE IN VARIABLE WIND DIRECTION WITH WIND SPEEDS OF 8
  KTS OR LESS.

* MODERATE CONFIDENCE ON WIND TRENDS THIS EVENING WITH HIGH
  CONFIDENCE AFTER.

* LOW CONFIDENCE IN ARRIVAL OF LOW CLOUDS AND IN HEIGHTS LATE
  TONIGHT OR SUNDAY. THESE MAY ARRIVE AS IFR CIGS.

* LOW CONFIDENCE ON ANY FREEZING DRIZZLE OCCURRING SUNDAY...WITH
  THE LIKELIHOOD THAT IF IT WERE TO OCCUR IT WOULD BE BRIEF.

//OUTLOOK FOR ORD/MDW FOR 00Z MONDAY-12Z SATURDAY...UPDATED 12Z...

SUNDAY NIGHT...RAIN...IFR CIGS AND VISIBILITY IN FOG LIKELY.

MONDAY...CHANCE OF RAIN AND SNOW. MVFR POSSIBLE.

TUESDAY...VFR.

WEDNESDAY...SLIGHT CHANCE RAIN OR SNOW...OTHERWISE VFR.

THURSDAY...VFR.

FRIDAY...VFR.

.MARINE...
239 PM CST

WITH HIGH PRESSURE MOVING EAST TONIGHT AND LOW PRESSURE BEGINNING TO
DEVELOP IN THE UPPER PLAINS...WINDS ACROSS LAKE MI WILL BE ON THE
INCREASE. TEMPERATURE LAPSE RATES OVER THE LAKE WILL INITIALLY BE
FAVORABLE LATE TONIGHT INTO SUNDAY TO SUPPORT GALE FORCE GUSTS. BY
SUNDAY NIGHT...WARM ENOUGH AIR IS LIKELY TO LOWER THE INVERSION AND
LIMIT THE AMOUNT OF GUSTS. STILL...SUSTAINED FORCE WINDS WILL LIKELY
BE 25 TO 30 KT. AS THE DEEPENING LOW PRESSURE MOVES NORTHEAST ACROSS
WESTERN WI ON SUNDAY NIGHT...IT WILL SWING A COLD FRONT EAST ACROSS
THE LAKE. THIS WILL TURN WINDS WESTERLY. GUSTS WITHIN THE COLD AIR
ADVECTION BEHIND THE FRONT ON MONDAY LOOK EVEN MORE IMPRESSIVE THAN
ON THE WARM AIR ADVECTION SIDE TOMORROW...AND GALES TO 40 KTS ARE
POSSIBLE.
