AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
1151 AM CST MON NOV 28 2011

.DISCUSSION...
1043 AM CST

LIGHT LAKE EFFECT SHOWERS CONTINUE TO PIVOT NORTHWEST AROUND THE
SOUTHWEST PERIPHERY OF THE LAKE. CURRENTLY SEEING SOME LIGHT LAKE
EFFECT RAIN AND SNOW SHOWERS COMING INTO COOK COUNTY. WITH
INVERSION HEIGHTS LOWERING WOULD STILL ANTICIPATE THE LAKE EFFECT
TO DISSIPATE BY EARLY AFTERNOON. SOME HOLES IN THE STRATUS
DEVELOPED DOWNWIND OF THE LAKE DUE TO BETTER MIXING...WITH THAT
HOLE TRANSLATING WESTWARD ACROSS THE CWA NOW. ALSO SEEING A FEW
OTHER HOLES OPEN UP...HOWEVER ANY HOLES THERE ARE TODAY WILL FILL
IN AS CLOUD SHIELD IN ADVANCE OF SOUTHERN UPPER LOW SPREADS FROM
SE TO NW ACROSS THE AREA.

IZZI

//PREV DISCUSSION...
351 AM CST

THE MAIN FORECAST CONCERNS ARE PRECIPITATION CHANCES...TYPES AND
AMOUNTS TUESDAY AND TUESDAY NIGHT AND POTENTIAL FOR VERY WINDY
CONDITIONS ON TUESDAY.

THE CLOUDS APPEAR TO NOT BE IN A HURRY TO GO ANYWHERE AS A
SUBSIDENCE INVERSION HAS TRAPPED THE MOISTURE IN THE LOWEST FEW
THOUSAND FEET ABOVE GROUND LEVEL. REGIONAL SATELLITE IMAGERY SHOWS A
ROBUST AREA OF MVFR CLOUD COVER ACROSS MUCH OF THE CENTRAL PART OF
THE COUNTY. CONSIDERING THAT MIXING WILL BE MINIMAL TODAY I EXPECT
THESE CLOUDS TO HANG AROUND AT LEAST INTO THE EARLY AFTERNOON HOURS
IF NOT THE ENTIRE DAY. THIS CLOUD COVER WILL KEEP TEMPERATURES VERY
COOL WITH HIGHS IN THE UPPER 30S TO THE LOW 40S.

THE MAIN STORY CONTINUES TO BE WITH THE EVOLUTION OF THE UPPER LOW
ACROSS THE LOWER MISSISSIPPI VALLEY. THE 00 UTC MODEL GUIDANCE IS IN
DECENT AGREEMENT WITH THE DEEPENING OF THIS SYSTEM AS IT SLOWLY
MOVES EAST NORTHEAST TOWARDS THE OHIO VALLEY ON TUESDAY AND TUESDAY
NIGHT. THIS SYSTEM LOOKS TO BEGIN TO TRANSPORT A RATHER LARGE AMOUNT
OF MOISTURE NORTHWESTWARD FROM THE SOUTHEASTERN CONUS LATER
TODAY AND TONIGHT. PRECIPITABLE WATER VALUES APPEAR TO APPROACH 1
INCH ACROSS MY NORTHWEST INDIANA COUNTIES BY THIS EVENING. AT THE
SAME TIME...A BAND OF MID LEVEL FRONTOGENESIS LOOKS TO SET UP WITHIN
A DEFORMATION ZONE ALONG THE NORTHERN AND NORTHWEST PERIPHERY OF THE
SURFACE LOW LATE TONIGHT THROUGH TUESDAY EVENING. INITIALLY...STRONG
WARM AIR ADVECTION/ISENTROPIC UPGLIDE WILL PRODUCE AN ATMOSPHERE
CONDUCIVE TO EFFICIENT RAINFALL PRODUCTION. THIS SHOULD LEAD TO SOME
MODERATE TO HEAVY RAINFALL LATER TONIGHT INTO TUESDAY...PRIMARILY
ACROSS NORTHWEST INDIANA AND SOME OF THE ADJACENT ILLINOIS COUNTIES.
HOWEVER...CONDITIONS WILL BE MUCH LESS CONDUCIVE TO HEAVY RAINFALL
FARTHER NORTHWEST TOWARDS NORTH CENTRAL AND NORTHEASTERN ILLINOIS.
THEREFORE...THERE WILL LIKELY BE A STRONG GRADIENT FROM HEAVY
RAINFALL ACROSS NORTHWESTERN INDIANA TO LITTLE TO NO RAINFALL ACROSS
NORTH CENTRAL ILLINOIS. THE MAIN CHALLENGE WILL BE DETERMINING THE
PLACEMENT OF THIS GRADIENT.

RAINFALL DOES NOT APPEAR TO BE THE ONLY PRECIP TYPE WITH THIS LOW.
GIVEN THAT THIS IS A VERY DYNAMIC SYSTEM...WITH A CLOSED OFF MID
LEVEL CIRCULATION...THERE WILL LIKELY BE STRONG DYNAMIC COOLING
EFFECTS AS THE UPPER LOW DEEPENS AND MOVES NORTHEASTWARD TOWARDS THE
OHIO VALLEY. THIS ATMOSPHERIC COOLING WILL ADD ANOTHER COMPLEXITY TO
THE FORECAST...AS IT IS QUITE POSSIBLE THAT THERE WILL BE A BAND OF
HEAVY RAIN THAT QUICKLY TRANSITIONS TO A BAND OF MODERATE TO HEAVY
SNOW ACROSS NORTHERN INDIANA AND WEST CENTRAL ILLINOIS LATE TUESDAY
AND TUESDAY EVENING. A PERIOD OF ACCUMULATING SNOWFALL APPEARS TO
BE POSSIBLE ACROSS THESE AREAS LATE TUESDAY AFTERNOON AND EVENING.
HOWEVER...THE AMOUNTS OF SNOW WILL BE LARGELY DEPENDENT ON THE
SNOWFALL RATES. GIVEN TEMPERATURES WILL BE HOVERING AT OR JUST
ABOVE FREEZING IT WILL TAKE SOME HEAVY SNOW TO EVEN RESULT IN
ACCUMULATIONS. AT THIS TIME...IT APPEARS THAT THERE MAY BE A BAND
OF SNOW HEAVY ENOUGH TO RESULT IN SOME ACCUMULATIONS.
HOWEVER...THE EXACT PLACEMENT OF THIS POSSIBLE SNOW BAND REMAINS
IN QUESTION.

IF THIS WAS NOT ENOUGH...NORTHERLY WINDS WILL ALSO BE STRONG ON
TUESDAY AND TUESDAY EVENING AS THE SURFACE LOW DEEPENS AND INTERACTS
WITH HIGH PRESSURE ACROSS THE PLAINS TO CREATE A STRONG PRESSURE
GRADIENT ACROSS THE REGION. WINDS WILL BE AT OR JUST BELOW ADVISORY
CRITERIA AWAY FROM THE LAKE. HOWEVER...THE NEAR SHORE COUNTIES
WILL LIKELY EXPERIENCE AT LEAST ADVISORY CRITERIA WINDS OFF OF
LAKE MICHIGAN. NORTHERLY WINDS MAY GUST AS HIGH AS 55 MPH AT TIMES
ON TUESDAY IN AREAS NEAR THE LAKE. THE STRONG WINDS WILL ALSO LEAD
TO 15 TO 20 FT WAVES OFF OF LAKE MICHIGAN..WHICH COLD CAUSE SOME
LAKE SHORE FLOODING PROBLEMS.

FOLLOWING THIS SYSTEM...THERE WILL BE A COUPLE OF QUITE DAYS BEFORE
ANOTHER COLD FRONT AND MID LEVEL WAVE PUSH ACROSS THE AREA ON FRIDAY
MORNING. THIS COULD RESULT IN A LITTLE MORE LIGHT SNOW ACROSS THE
AREA. HOWEVER...THIS WILL NOT BE ANYTHING OF CONSEQUENCE.

LATER IN THE PERIOD FORECAST UNCERTAINTY INCREASES AS THE MODELS ARE
HAVING TROUBLE FORECASTING THE POTENTIAL INTERACTION BETWEEN
NORTHERN STREAM SHORT WAVES WITH AN UPPER LOW THAT IS EXPECTED TO
DIG ACROSS THE SOUTHWESTERN CONUS LATER THIS WEEK. OVERALL...THERE
IS THE POTENTIAL TO HAVE MORE INCLEMENT WEATHER LATER IN THE
WEEKEND.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 18Z...

* MVFR CIGS PERSISTING THROUGH THE AFTERNOON AND EVENING.
* NORTHEAST WIND INCREASING TONIGHT...BECOMING GUSTY TO 30 KT

* RAIN DEVELOPING LATE TONIGHT MAINLY SOUTHEAST OF ORD.

PAW

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

LAKE EFFECT CONDITIONS THAT PRODUCED SOME SNOW AND MIXED
RAIN/SNOW OVER NORTHEAST IL AND NORTHWEST IN THIS MORNING HAVE
BECOME LESS FAVORABLE. A FEW PATCHES OF PRECIPITATION MAY LAST
INTO EARLY AFTERNOON...WITH LITTLE RESTRICTION TO VISIBILITY.

LOW PRESSURE SYSTEM DEVELOPING IN THE OHIO VALLEY WILL BECOME THE
DOMINANT INFLUENCE ON THE TERMINALS OVERNIGHT INTO TUESDAY. THE
INITIAL IMPACT WILL BE INCREASING WINDS IN THE OVERNIGHT
HOURS...WITH NORTHEAST GUSTS APPROACHING 30 KT BY TUESDAY MORNING.
RAIN ASSOCIATED WITH THE SYSTEM WILL BE DEVELOPING TOWARD THE
TERMINALS OVERNIGHT...THOUGH THE EDGE OF THE RAIN WILL LIKELY BE
SOMEWHERE ACROSS NORTHEAST IL. IFR CIGS POSSIBLE WITH THE HEAVIER
RAIN AREAS ON TUESDAY.

.MARINE...
400 AM CST

A RIDGE OF HIGH PRESSURE INCHES EXTENDS FROM EASTERN ONTARIO
SOUTHWEST TO THE SOUTHERN PLAINS EARLY THIS MORNING. THE NORTHERN
PORTION OF THIS RIDGE WILL MOVE EAST TO QUEBEC TODAY WHILE LOW
PRESSURE DEEPENS IN NORTHERN GEORGIA. THIS LOW WILL TRACK NORTHWARD
ACROSS THE OHIO VALLEY TONIGHT AND TO THE EASTERN GREAT LAKES
TUESDAY. MEANWHILE...STRONG HIGH PRESSURE WILL MOVE EAST ACROSS THE
NORTHERN AND CENTRAL PLAINS. THE STRONG PRESSURE GRADIENT OVER THE
UPPER GREAT LAKES BETWEEN THE LOW AND THE HIGH DURING TONIGHT AND
TUESDAY WILL RESULT IN NORTH AND NORTHWEST WINDS INCREASING
SIGNIFICANTLY OVERNIGHT...AND LIKELY TO BE GALE FORCE AND EVEN HIGH
GALES ON PORTIONS OF LAKE MICHIGAN BY DAYBREAK TUESDAY. WINDS
WILL BEGIN TO SLACKEN WEDNESDAY AS THE LOW CONTINUES OFF TO THE
NORTHEAST ACROSS SOUTHERN QUEBEC AND THE RIDGE OF HIGH PRESSURE
SHIFTS FROM THE UPPER MIDWEST TO OVER THE WESTERN GREAT LAKES.

WHILE NORTH WINDS HAVE BEEN GRADUALLY DIMINISHING OVER SOUTHERN LAKE
MICHIGAN OVERNIGHT WAVE HEIGHTS ARE STILL IN THE 4 TO 6 FOOT RANGE
SO THE SMALL CRAFT ADVISORY WILL BE ALLOWED TO CONTINUE TODAY. THERE
MAY BE A FEW HOUR WINDOW DURING THE LATER AFTERNOON AND EARLY
EVENING WHEN WAVES WILL HAVE FALLEN BELOW CRITERIA...BUT WINDS WILL
BEGINNING CRANKING UP DURING THE EVENING ONCE AGAIN CREATING
HAZARDOUS CONDITIONS FOR SMALL CRAFT TONIGHT.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.

NORTH TO NORTHEAST WINDS WILL GUST TO AROUND 40 MPH TUESDAY...
WITH GUSTS OVER 50 MPH POSSIBLE NEAR LAKE MICHIGAN. LARGE AND

PERIODS OF MODERATE TO HEAVY RAINFALL WILL CONTINUE ON TUESDAY
ACROSS PORTIONS OF NORTHWESTERN INDIANA AND THE ADJACENT EAST
CENTRAL COUNTIES IN ILLINOIS. RAINFALL AMOUNTS IN EXCESS OF AN
INCH ARE POSSIBLE ACROSS THESE AREAS. IN ADDITION...THERE IS THE
POTENTIAL THAT THIS RAINFALL COULD CHANGE OVER TO A PERIOD OF
MODERATE TO HEAVY SNOW LATE TUESDAY AFTERNOON AND EVENING AS
COLDER AIR MOVES ACROSS THE REGION. ALTHOUGH UNCERTAINTY REMAINS
HIGH WITH THIS POTENTIAL TRANSITION FROM RAIN TO SNOW...THERE COULD
BE SOME ACCUMULATING SNOW LATE TUESDAY AND TUESDAY EVENING THAT
COULD LEAD TO SOME HAZARDOUS TRAVEL CONDITIONS. AT THIS TIME...IT
APPEARS THE MAIN THREAT FOR SOME ACCUMULATING SNOW WOULD BE SOUTH
OF INTERSTATE 80 AND EAST OF INTERSTATE 57.
