AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
903 PM CDT WED MAY 23 2012

.DISCUSSION...
328 PM CDT

SEVERAL FORECAST CONCERNS COMING UP FOR THE NEXT FEW DAYS...
INCLUDING UNSEASONABLY WARM TEMPERATURES...STRONG/GUSTY WINDS...
AND THUNDERSTORM POTENTIAL...WITH THE POSSIBILITY OF SEVERE
THUNDERSTORMS FOR NORTH-CENTRAL AND NORTHWESTERN ILLINOIS.

HOWEVER...FOR THE REMAINDER OF TODAY AND TONIGHT...CONDITIONS WILL
REMAIN MOSTLY CLEAR AND DRY AS SFC HIGH PRESSURE PASSES OFF TO THE
EAST.  DEEPENING LOW PRESSURE OVER THE CENTRAL PLAINS WITH THE HIGH
NOW CENTERED WEST OF THE CWA HAS ALLOWED FOR WINDS TO TURN MORE
SELY...BRINGING INCREASING WARMTH TO MUCH OF THE AREA...WITH
TEMPERATURES REACHING INTO THE UPPER 70S AND LOWER 80S THIS
AFTERNOON.  A WEAK LAKE BREEZE PUSHING INLAND INTO FAR NERN IL HAS
KEPT THE LAKE FRONT FROM CHICAGO NORTHWARD A BIT COOLER...WITH
TEMPERATURES TOPPING OUT IN THE LOWER 70S BEFORE DROPPING BACK INTO
THE UPPER 60S.  WITH AN ERODING UPPER RIDGE STILL IN PLACE OVER THE
REGION...SKIES HAVE REMAINED MOSTLY CLEAR TODAY...BUT CLOUD COVER
SHOULD BE ON THE INCREASE THROUGH THE NIGHT AS THE UPPER TROUGH AND
ASSOCIATED SFC TROUGH/COLD FRONT PUSH ACROSS THE PLAINS AND TOWARD
THE MISSISSIPPI VALLEY.

FOR THURSDAY...THE QUIET WEATHER WILL QUICKLY COME TO AN END.  AS
THE COLD FRONT AND SFC TROUGH PUSH EWD...THE SFC PRESSURE GRADIENT
WILL QUICKLY STRENGTHEN WITH A STRONG LOW LEVEL JET CURRENTLY OVER
THE PLAINS SHIFTING EWD.  BY TOMORROW AFTERNOON...THE GUIDANCE IS
INDICATING THAT A SSWLY JET WITH 850MB WINDS OF 55-60KT SHIFTING
OVER ERN IOWA AND NWRN IL AND INTO SWRN WISCONSIN.  THE INITIAL
CONCERN WILL BE STRONG GUSTY SFC WINDS...WITH 40-45MPH WINDS LIKELY
MIXING DOWN TO THE SFC BY LATE MORNING AND THEN CONTINUING THROUGH
THE DAY.  THE STRONG SOUTH WINDS WILL ALSO USHER IN INCREASING
WARMTH...WITH TEMPERATURES LIKELY APPROACHING 90F.  A SLIGHT EAST OF
SOUTH COMPONENT TO THE WIND FIELD MAY STILL ALLOW FOR SOME LAKE
COOLED AIR TO PUSH INLAND...BUT ANY LAKE INFLUENCE SHOULD BE
CONFINED TO THE IMMEDIATE LAKE FRONT OF LAKE COUNTY IL.  AS LOW
LEVEL TRAJECTORIES WILL STILL HAVE A SIGNIFICANT OVERLAND
FETCH...SFC DEWPOINTS WILL BE SLOW TO INCREASE...AND ANY SIGNIFICANT
DEWPOINT POOLING WILL BE FOCUSED NEAR THE FRONTAL BOUNDARY...WITH
DEWPOINTS ONLY IN THE LOWER 50S MOVING INTO NRN IL/IN BY TOMORROW
AFTERNOON.  BY LATE AFTERNOON...THE FOCUS OF CONCERN WILL TRANSITION
OVER TO THUNDERSTORM POTENTIAL.  WITH STRONG WARM ADVECTION SETTING
UP IN THE WARM SECTOR...MUCH OF THE AREA WILL BE CAPPED.
THEREFORE...EXPECT THE GREATEST THUNDERSTORM POTENTIAL TO BE
COINCIDENT WITH THE COLD FRONT AND NEAR THE MAIN SFC LOW.  THE
LATEST SHORT RANGE MODEL GUIDANCE INDICATES THAT THE COLD FRONT
SHOULD CROSS THE MISSISSIPPI RIVER INTO NWRN IL BY 21-00Z TOMORROW
AFTERNOON.  BUT...BY THIS TIME...THE MAIN SFC LOW WILL BE LIFTING
INTO NWRN WISCONSIN.  WHILE THE GREATEST SEVERE THREAT SHOULD BE
NEAR THIS DEEPENING SFC LOW...THERE WILL REMAIN A SEVERE THREAT
ESPECIALLY ALONG THE FRONT AS IT PUSHES INTO NWRN/NCNTRL IL DURING
AND JUST AFTER THE PERIOD OF STRONGEST SFC HEATING.  SOME OF THE
GUIDANCE...IN PARTICULAR THE ECMWF AND GEM ARE SHOWING DEVELOPMENT
OF A WEAK SECONDARY SFC WAVE ALONG THE COLD FRONT OVER NWRN IL AT
00Z.  THIS WOULD ONLY ACT TO INCREASE THE SEVERE POTENTIAL BY
BACKING WINDS OVER NWRN/NCNTRL IL A LITTLE MORE SELY...INCREASING
LOW LEVEL DIRECTIONAL SHEAR.  GIVEN THE MODEST SHEAR...STRONG LOW
LEVEL JET...BUT LIMITED LOW LEVEL MOISTURE...THE GREATEST SEVERE
THREATS WILL BE LARGE HAIL AND STRONG/DAMAGING WINDS.

FOR FRIDAY AND INTO THE WEEKEND...THE FORECAST CONCERN WILL LARGELY
BE UNSEASONABLY WARM TEMPERATURES.  THERE IS STILL SOME DISAGREEMENT
AMONG THE MODELS ON EXACTLY HOW THE COLD FRONT WILL EVOLVE...THOUGH
THERE IS AN INCREASING CONSENSUS OF THE NAM/GFS/GEM IN PUSHING THE
COLD FRONT...AT LEAST INITIALLY...JUST SOUTH OF THE CWA...BRINGING
SOME COOLING TO THE NRN PORTIONS OF THE CWA AND ALONG THE LAKE FOR
FRIDAY.  TEMPERATURES GENERALLY NORTH OF I-80 SHOULD DROP BACK INTO
THE LOWER 80S...OR UPPER 70S ALONG THE LAKE...WHILE THE SRN PORTIONS
OF THE AREA REMAIN CLOSE TO 90F.  WHERE THE MODELS DIVERGE IS IN HOW
THEY HANDLE THE RETURN OF THE FRONT BACK NORTH AS A WARM FRONT.  THE
PREFERRED SOLUTION RIGHT NOW IS TO PUSH THE FRONT BACK NWRD THROUGH
THE DAY ON FRIDAY.  THE ECMWF IS NOW THE OUTLIER IN GENERATING
WIDESPREAD PCPN WITH THE FRONT AS IT PUSHES NWD...WHILE THE OTHER
MODELS WANT TO KEEP THE AREA GENERALLY DRY.  EVEN THOUGH THE ECMWF
IS A DISTINCT OUTLIER IN THE MODEL SOLUTION ENVELOP...DO NOT FEEL
CONFIDENT ENOUGH IN THE OTHER GUIDANCE TO TOTALLY DISCOUNT IT AS THE
ECMWF HAS HAD A VERY GOOD TRACK RECORD OF LATE.  SO...WILL MAINTAIN
SLIGHT CHANCE POPS DURING THE DAY FRIDAY.  BY FRIDAY EVENING...THERE
WILL BE BETTER UPPER LEVEL SUPPORT FOR THUNDER/PCPN DEVELOPMENT AS
IT LIFTS NWRD INTO WISCONSIN.  SO...CURRENTLY FEEL THAT THERE IS THE
BEST CHANCE FOR SHRA/TSRA JUST NORTH OF THE BOUNDARY AS IT LIFTS
NWD...WITH THE GREATEST CHANCES OVER FAR NRN IL/SRN WISCONSIN DURING
THE EVENING AND INTO THE OVERNIGHT HOURS.  BY SATURDAY...THERE MAY
STILL BE SOME HINT OF SELY FLOW BRINGING SOME LAKE COOLED AIR INTO
THE LAKEFRONT OF COOK AND LAKE COUNTIES IN ILLINOIS...BUT
OTHERWISE...NRN IL/IN SHOULD BE SOLIDLY IN WARM SECTOR AIR...WITH
TEMPERATURES IN THE UPPER 80S TO LOWER 90S OVER THE AREA ON
SATURDAY.  BY SUNDAY...LOW LEVEL WINDS SHOULD BE MORE
SWLY...ALLOWING THE WARMER AIR ALL THE WAY UP TO THE LAKEFRONT.
WITH AN UPPER HIGH BUILDING OVER THE SERN CONUS AND UPPER RIDGING
EXTENDING BACK INTO THE UPPER MIDWEST...SUNDAY WILL BE THE WARMEST
DAY OF THE WEEKEND...WITH TEMPERATURES POTENTIALLY REACHING INTO THE
LOWER TO MIDDLE 90S.

FOR THE FORECAST PERIOD...FOR MEMORIAL DAY THROUGH WEDNESDAY...
MEMORIAL DAY SHOULD STILL BE QUITE WARM...THOUGH TEMPS SHOULD BE A
LITTLE LOWER...IN THE UPPER 80S TO AROUND 90F...AS THE NEXT UPSTREAM
SYSTEM MOVES ACROSS THE NRN PLAINS AND INTO THE UPPER MISSISSIPPI
VALLEY.  THIS SYSTEM WILL BRING ANOTHER CHANCE FOR SOME SHOWERS AND
THUNDERSTORMS FOR LATE MONDAY AFTERNOON AND THROUGH THE NIGHT...WITH
SOME SHOWERS POSSIBLY LINGERING INTO TUESDAY MORNING. CONDITIONS
SHOULD RETURN CLOSER TO SEASONAL NORMAL LEVELS FOR TUESDAY AND
WEDNESDAY FOLLOWING THE PASSAGE OF THE COLD FRONT.

.FIRE WEATHER...
524 PM CDT

HAVE SOME CONCERN FOR RED FLAG CONDITIONS ON THURSDAY BUT
POTENTIAL IS MARGINAL AT THIS TIME. CURRENT FORECAST IS IN GOOD
SHAPE BUT THERE IS SOME POTENTIAL FOR BETTER MIXING OF DRY AIR
INTO EARLY AFTERNOON WHICH WOULD ALLOW DEW POINTS TO BE SEVERAL
DEGREES LOWER THAN FORECAST...HOWEVER MOISTURE WILL BE IN THE
PROCESS OF TRYING TO INCREASE AHEAD OF THE APPROACHING FRONT. IN
ADDITION...MANY AREAS HAVE SEEN RECENT RAINFALL BUT THERE HAVE
ALSO BEEN AREAS THAT HAVE BEEN MUCH DRIER SUPPORTING A LOWER FUEL
MOISTURE. THE PRIMARY CONCERNS ARE THAT THESE RELATIVELY DRY
CONDITIONS WILL COMBINE WITH STRONG SOUTHERLY WINDS ON THURSDAY.
WIND SPEEDS AT 20 FEET ARE EXPECTED TO INCREASE TO AROUND 20
MPH...WITH GUSTS POSSIBLY IN EXCESS OF 40 MPH AT TIMES DURING THE
AFTERNOON. WILL NOT HOIST ANY HEADLINES AT THIS TIME GIVEN THE
UNCERTAINTY BUT WILL CONTINUE TO MONITOR THE POTENTIAL FOR
WARMER/DRIER CONDITIONS FOR A TIME EARLY THURSDAY AFTERNOON.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 02Z...

* STRONG SOUTHERLY WINDS ON THURSDAY.

KJB

//DISCUSSION...UPDATED 00Z...

THE MAIN CONCERNS DURING THE PERIOD WILL BE THE STRONG SOUTHERLY
WINDS EXPECTED TO DEVELOP ACROSS THE TERMINALS ON THURSDAY.

A POTENT AREA OF LOW PRESSURE...CURRENTLY TAKING SHAPE ACROSS THE
FRONT RANGE OF THE COLORADO ROCKIES...WILL LIFT NORTHEASTWARD ACROSS
IOWA AND THE UPPER MISSISSIPPI RIVER VALLEY ON THURSDAY. AS THIS
OCCURS...THE PRESSURE GRADIENT WILL STRENGTHEN ACROSS NORTHERN
ILLINOIS. THIS WILL SUPPORT STRONG SUSTAINED SOUTHERLY WINDS AROUND
20 TO 25 KT DURING THE AFTERNOON. IN ADDITION...RELATIVELY DRY
CONDITIONS AND ABUNDANT SUNSHINE WILL LEAD TO DEEP ATMOSPHERIC MIXING.
THE CURRENT GUIDANCE SUGGESTS THAT AFTERNOON MIXING COULD TAP INTO
THE 45 TO 50 KT WINDS APPROXIMATELY 3,500 TO 4,000 FT AGL.
ALTHOUGH WINDS OF THIS INTENSITY WILL LIKELY NO BE REALIZED AT THE
SURFACE...WIND GUSTS BETWEEN 35 TO 40 KT ARE QUITE POSSIBLE. IT
APPEARS THE STRONGEST WINDS WILL BE ACROSS NORTH CENTRAL
ILLINOIS...INCLUDING KRFD. SLIGHTLY LIGHTER WINDS ARE EXPECTED
ACROSS NORTHEASTERN ILLINOIS AND NORTHWESTERN INDIANA.

THERE WILL BE A SMALL THREAT FOR FOR THUNDERSTORMS ON THURSDAY
EVENING...ESPECIALLY ACROSS NORTH CENTRAL AND NORTHWESTERN ILLINOIS
AS COLD FRONT APPROACHES THE AREA. THIS IS CURRENTLY BEYOND THE 24
HOUR TAF PERIOD FOR KRFD.

KJB

//ORD AND MDW CONFIDENCE...UPDATED 02Z...

* HIGH CONFIDENCE IN ALL FORECAST ELEMENTS.

KJB

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

* FRIDAY...CHANCE OF SHRA/TSRA IN THE AFTERNOON AND EVENING...ELSE VFR.
* SATURDAY...VFR.
* SUNDAY...VFR.
* MONDAY...CHANCE OF SHRA/TSRA...GUSTY SOUTHWEST WINDS.
* TUESDAY...SLIGHT CHANCE OF SHRA.

.MARINE...
203 PM CDT

DESPITE LOW PRESSURE TO THE NORTHWEST...LOW PRESSURE DEVELOPING
OVER THE CENTRAL PLAINS...AND A TIGHT PRESSURE GRADIENT SITUATED
JUST TO THE WEST OF THE LAKE...RELATIVELY LIGHT FLOW STILL REMAINS
OVER MUCH OF THE LAKE THIS AFTERNOON. THIS WILL CHANGE TONIGHT
INTO THURSDAY AS HIGH PRESSURE CONTINUES TO SHIFT EAST AND THIS
TIGHT PRESSURE GRADIENT SHIFTS OVERHEAD. THIS WILL HELP SOUTHERLY
WINDS INCREASE TONIGHT THROUGH THURSDAY WITH WINDS REALLY PEAKING
BY THURSDAY AFTERNOON AND EVENING AS THIS LOW TRACKS NORTHEAST
ACROSS MUCH OF THE MISSISSIPPI VALLEY. DESPITE WINDS REALLY
PICKING UP ON THURSDAY...VERY STABLE CONDITIONS WILL BE IN PLACE
HELPING TO LIMIT OVERALL GUST POTENTIAL AS WELL AS WAVE HEIGHTS.
THERE STILL REMAINS SOME CONCERN FOR GALE FORCE WINDS DURING THE
PERIOD FROM THURSDAY AFTERNOON INTO THURSDAY EVENING...BUT WITH
GALES TO REMAIN MORE SPORADIC IN NATURE. DUE TO THIS FACT AS WELL
AS SOME UNCERTAINTY REMAINING...HAVE OPTED NOT TO UPGRADE THE
CURRENT GALE WATCH FOR THE OPEN WATERS BUT RATHER KEEP IT GOING AS
IS. FOR THE NEARSHORE...HAVE DECIDED TO DO THE SAME AS THE OPEN
WATERS. THINK THERE WILL BE ONLY ABOUT A 1 TO 3 HOUR PERIOD
THURSDAY AFTERNOON WHEN GALES WILL BE POSSIBLE. THIS LOW WILL THEN
CONTINUE TO TRACK TO THE NORTHEAST ON FRIDAY WITH WINDS SLOWLY
DIMINISHING ACROSS THE LAKE...WITH HIGH PRESSURE BRIEFLY MOVING
OVER THE CENTRAL GREAT LAKES FRIDAY NIGHT.
