AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
329 PM CDT WED SEP 28 2011

.DISCUSSION...
251 AM CDT

SHORT TERM (TODAY THROUGH FRIDAY NIGHT)...

THE LITTLE UPPER LOW THAT COULD WILL FINALLY GET BOOTED OUT OF THE
AREA AFTER SPENDING THE BETTER PART OF A WEEK IN THE AREA...BUT NOT
BEFORE GIVING US ONE MORE DAY OF CLOUDINESS AND OCCASIONAL SHOWERS
AS SPIRAL BANDS WHIRL AROUND THE UPPER LOW TODAY. THE UPPER LOW
HAS ALREADY STARTED TO INCH ITS WAY EASTWARD AND THIS TREND WILL
CONTINUE AS THE ZONAL FLOW TO THE NORTH OF THE UPPER LOW BREAKS
DOWN INTO A MUCH MORE AMPLIFIED PATTERN.

SPEAKING OF WHICH...THE NEXT BIG WEATHER MAKER IS THE SHORTWAVE OVER
SOUTHERN BRITISH COLUMBIA EARLY THIS MORNING. NUMERICAL GUIDANCE IS
IN GOOD AGREEMENT ON TAKING THIS SHORTWAVE EAST ACROSS THE CANADIAN
ROCKIES TODAY...BEFORE IT TURNS MORE SOUTHEASTWARD AND CARVES OUT A
VIGOROUS TROUGH OVER THE GREAT LAKES. A SURFACE LOW AND FRONT WILL
RAPIDLY DEVELOP TONIGHT WITH THE SURFACE LOW PROGGED TO TRACK INTO
THE NORTHERN GREAT LAKES AND QUICKLY DEEPEN THURSDAY INTO THURSDAY
NIGHT WITH THE TRAILING COLD FRONT SWEEPING ACROSS THE CWA THURSDAY
AFTERNOON.

OBVIOUSLY THERE WILL BE NO TIME FOR A RETURN FLOW OF DEEP MOISTURE
IN ADVANCE OF THIS FRONT...HOWEVER VERY STRONG LARGE SCALE ASCENT
WITH THE RAPIDLY DEEPENING TROUGH COULD BE ENOUGH TO COMPENSATE FOR
THE RELATIVE LACK OF MOISTURE AND ALLOW FOR A BAND OF STRONG FORCED
CONVECTION TO DEVELOP AND BUILD SOUTHWARD ALONG THE FRONT THURSDAY.
INSTABILITY SHOULD BE FAIRLY WEAK...HOWEVER THE NEAR 200M 500MB
HEIGHT FALLS SUGGEST THAT THE FORCING MAY BE ENOUGH TO COMPENSATE
FOR MINIMAL INSTABILITY AND SUPPORT ADDING AT LEAST A SLIGHT
CHANCE OF THUNDERSTORMS TO THE GRIDS. BEST CHANCE OF PRECIP AND
THUNDER APPEARS TO BE OVER OUR EASTERN CWA AS I EXPECTED
CONVECTION TO BUILD SOUTHWESTWARD DOWN THE FRONT AS THE FRONT
ITSELF RACES SOUTHEASTWARD ACROSS THE CWA. IT WILL BE A BIT OF A
RACE AS TO HOW FAR THROUGH THE CWA THE FRONT WILL BE BEFORE IT
LIGHTS UP AND FOR THAT REASON KEPT POPS QUITE MODEST.

NEXT BIG STORY WILL TURN TO THE BIG POTENTIAL WITH THIS STORM.
STRONG COLD AIR ADVECTION AND PRESSURE RISES BEHIND THE FRONT WILL
LIKELY KEEP THE BOUNDARY LAYER WELL MIXED THURSDAY NIGHT...ALLOWING
FOR WINDS TO STAY UP AND QUITE GUSTY. BUFKIT SOUNDINGS SUPPORT THE
POTENTIAL FOR WIND GUSTS OVER 40 MPH AT TIMES THURSDAY NIGHT INTO
FRIDAY MORNING AND COULD EVEN END UP NEEDING WIND HEADLINES.

NORTHWEST WINDS WILL THEN VEER TO A MORE NORTHERLY DIRECTION LATER
FRIDAY INTO FRIDAY NIGHT WHICH SHOULD SPREAD THE LAKE EFFECT SHOWERS
WESTWARD INTO OUR NORTHWEST INDIANA COUNTIES. FULL FETCH AND LIKELY
ADDITION OF A LAND BREEZE CONVERGENCE ZONE SUPPORTS DRAMATICALLY
RAISING POPS OVER NORTHWEST INDIANA...AND CANNOT EVEN COMPLETELY
RULE OUT A CLAP OR TWO OF THUNDER GIVEN THE VERY STRONG PUSH OF COLD
AIR OVER THE LAKE.

FARTHER WEST IN OUR CWA...WINDS SHOULD BEGIN TO SUBSIDE AND SKIES
CLEAR LIKELY SETTING THE STAGE FOR THE COLDEST NIGHT SO FAR THIS
SEASON. IF CURRENT MODEL TRENDS HOLD...THEN ITS LIKELY THE MORE
SHELTER VALLEYS AND HOLES WOULD SEE FROST SATURDAY MORNING...BUT
DOES APPEAR AS THOUGH ENOUGH OF A GRADIENT 5-10 MPH SHOULD PREVENT A
WIDESPREAD FROST. ACTUALLY AM ALMOST AS CONCERNED ABOUT PORTIONS OF
OUR WESTERN CWA FLIRTING WITH THE FREEZING MARK.

IZZI

LONG TERM (SATURDAY THROUGH TUESDAY)...

HIGH PRESSURE MOVES IN FROM THE WEST SATURDAY MORNING.
HOWEVER...WITH NORTH WINDS AND A MODERATE TO HIGH TEMPERATURE
DIFFERENCE BETWEEN LAKE MICHIGAN AND 850H...LAKE EFFECT PRECIP WILL
PERSIST THROUGH THE EARLY PART OF SATURDAY OVER NORTHWESTERN
INDIANA.  EXPECTING THE LAKE EFFECT MACHINE TO SHUT OFF BY LATE
SATURDAY MORNING...BUT LAKE EFFECT CLOUD COVER WILL LIKELY LINGER
FOR THE MAJORITY OF SATURDAY.  HIGH PRESSURE REMAINS IN THE REGION
FOR THE REMAINDER OF THE EXTENDED FORECAST...LEADING TO A DRY
FORECAST.  ALSO HAVE A WARMING TREND IN PLACE THROUGH MID NEXT
WEEK...WITH MAX TEMPS ON TUESDAY REACHING INTO THE LOW 70S.
NIGHTTIME LOWS WILL REMAIN CHILLY...WITH MIN TEMPS IN THE UPPER 40S
AND LOW 50S.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 20Z...

* SCATTERED SHRA UNTIL EARLY EVENING. ISOLATED TSRA POSSIBLE.
* NORTHWEST TO NORTH WIND AROUND 10 KT TODAY.

PAW

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

VERTICALLY STACKED UPPER LOW AND SURFACE LOW COMBO THAT HAS BEEN
CIRCLING AROUND NORTHERN IL AND NORTHWEST IN FOR SEVERAL DAYS HAS
FINALLY BEGUN A SLOW MOVEMENT TO THE EAST. AREAS OF SHRA SWIRLING
AROUND THE LOW WILL BECOME MORE ISOLATED AND MOVE OUT OF THE
TERMINALS THIS EVENING.

THE NEXT SYSTEM IS NOT FAR BEHIND THE DEPARTING LOW. WINDS WILL
TURN MORE TO THE WEST AND SOUTHWEST OVERNIGHT BEFORE A COLD FRONT
MOVES ACROSS THE TERMINALS ON THURSDAY. THE BIGGEST IMPACT FROM
THIS FRONT WILL A MARKED INCREASE IN THE WIND SPEEDS AROUND MIDDAY
THURSDAY.

POTENTIAL FOR FOG DEVELOPMENT AGAIN TONIGHT WILL BE LIMITED DUE TO THE
DEPARTURE OF THE LOW AND THE CHANGE IN WIND DIRECTION. HAVE KEPT
THE MENTION OF MVFR VISIBILITY AT DPA AND NOT INTRODUCED ANYWHERE
ELSE.

PAW

//ORD AND MDW CONFIDENCE...UPDATED 20Z...

* HIGH CONFIDENCE IN SHRA AND POSSIBLE TSRA.
* MEDIUM CONFIDENCE IN WIND FORECAST.

PAW

//OUTLOOK FOR ORD/MDW FOR 00Z FRIDAY-12Z WEDNESDAY...UPDATED 12Z...

THURSDAY NIGHT...WINDY. SLIGHT CHANCE OF SHRA.

SATURDAY...VFR. SLIGHT CHANCE OF SHRA.
SUNDAY THROUGH TUESDAY...VFR.

.MARINE...
320 PM CDT

THE UPPER LEVEL CUTOFF LOW...AND ITS PARTNER AT THE SURFACE...THAT
HAVE BEEN HANGING AROUND SOUTHERN LAKE MICHIGAN FOR THE PAST FEW
DAYS FINALLY APPEAR TO BE GETTING KICKED OUT OF THE AREA OVERNIGHT
INTO EARLY TOMORROW.  THE TROUBLE IS...THE SYSTEM KICKING THEM OUT
IS GOING TO BE AN EVEN BIGGER PROBLEM THAN THE CUTOFF LOW.  FORECAST
MODELS ARE IN GOOD AGREEMENT WITH THE IDEA OF A RAPIDLY DEEPENING
SURFACE LOW OVER LAKE SUPERIOR EARLY TOMORROW AHEAD OF A DEVELOPING
UPPER LEVEL SYSTEM.  THIS DEEPENING SURFACE LOW IS FORECAST TO MOVE
ACROSS NORTHERN LAKE MICHIGAN TOMORROW AND INTO LAKE HURON BY
TOMORROW NIGHT.  A VERY TIGHT PRESSURE GRADIENT...THE DEEPENING
LOW...MUCH COOLER AIR OVER THE RELATIVELY WARMER LAKE SURFACE...AND
THE EFFICIENT MIXING DOWN OF STRONG WINDS ALOFT...ALL ARE EXPECTED
TO CONTRIBUTE TO A SEVERAL HOUR PERIOD OF FREQUENT STORM FORCE GUSTS
THURSDAY EVENING INTO FRIDAY MORNING.

NEARSHORE ZONES SHOULD BE A LITTLE MORE SHELTERED THAN THE OPEN
WATERS...ARE FARTHER SOUTH THAN THE ANTICIPATED AREA OF STRONGEST
WINDS. THUS HAVE DECIDED TO STAY WITH A GALE WARNING FOR THAT
AREA...STARTING OUT MIDDAY WHEN WINDS SHOULD START GUSTING ABOVE
SMALL CRAFT CRITERIA. GALES IN THE NEARSHORE SHOULD DIMINISH BY
FRIDAY NIGHT...BUT ANTICIPATE THE NEED FOR A SMALL CRAFT ADVISORY
UNTIL AT LEAST SATURDAY NIGHT.

STORM WARNING HEADLINE FOR THE OPEN WATERS WILL START MID
AFTERNOON THURSDAY AROUND THE TIME GALES ARE EXPECTED TO RAMP UP.
GUSTS TO STORM FORCE ARE NOT ANTICIPATED UNTIL LATER IN THE
EVENING...PEAKING AROUND MIDNIGHT. ALSO AM ANTICIPATING THE NEED
TO CONTINUE A GALE WARNING IN THE OPEN WATERS AFTER EXPIRATION OF
THE STORM WARNING...AT LEAST INTO FRIDAY NIGHT.
