AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
257 PM CDT MON JUN 17 2013

.DISCUSSION...
251 PM CDT

TONIGHT...
VISIBLE IMAGERY EARLY THIS AFTERNOON DEPICTS A CIRRUS SHIELD FROM
SOUTHEAST IOWA STRETCHING NORTHEAST ALONG I-80 IN ILLINOIS INTO
NORTHCENTRAL INDIANA. WATER VAPOR IMAGERY ALSO INDICATED AN
ABUNDANCE OF UPR LEVEL MOISTURE ASSOCIATED WITH THE CLOUDS...HOWEVER
SOME SUBSIDENCE WAS OCCURRING LATE THIS MORNING INTO THE AFTERNOON
HOURS AS DEW POINTS AT THE SFC WERE DROPPING INTO THE MID/UPR 50S
ACROSS THE CWFA. LLVL FLOW UNDER THE CLOUD SHIELD WAS GENERALLY
SOUTHWESTERLY...WHILE FURTHER NORTH WINDS WERE WESTERLY. IT APPEARS
THAT WHERE SKIES ARE MOSTLY SUNNY SLIGHTLY BETTER MIXING WAS
OCCURRING...WHICH WAS ALSO AIDING IN THE SUBSIDENCE AT THE SFC.

THE FOCUS FOR LATER THIS AFTERNOON/EVENING IS ON THE APPROACHING
FRONTAL BOUNDARY AND POTENTIAL FOR ISOLATED SHOWERS/THUNDERSTORMS
ALONG/JUST AHEAD OF THIS BOUNDARY. VISIBLE IMAGERY DOES SHOW A
NARROW CHANNEL OF A CUMULUS FIELD DEVELOPING ACROSS CENTRAL WISC
THIS AFTERNOON...STRETCHING NORTHWEST THROUGH MINN. A WEAK MID-LVL
WAVE WAS SLIDING SOUTHEAST THE UPPER MIDWEST...WHICH WILL BE THE
DRIVER FOR SOME ADDED LIFT INTO THIS CUMULUS FIELD. AS EXPECTED
ISOLATED SHOWERS/THUNDERSTORMS WERE DEVELOPING UNDER THIS CHANNEL OF
CUMULUS ACROSS CENTRAL WISC/EASTERN MINN. MID-LVLS ARE MUCH
COOLER...WITH STEEP LAPSE RATES TO THE NORTH ACROSS WISC. THIS
SUGGESTS THAT A FEW THUNDERSTORMS COULD EASILY GROW VERTICALLY AND
POSSIBLY PRODUCE SOME HAIL. FEEL THAT MOST OF THE LATE AFTN/EARLY
EVENING WILL END UP BEING DRY FOR THE CWFA. GUIDANCE CONTINUES TO
SUGGEST THAT THE BEST CHC FOR ANY PRECIP WILL LIKELY OCCUR AFT 00Z.
WITH MUCH OF THE CONVECTIVE POTENTIAL BEING DIURNALLY
DRIVEN...EXPECT THAT ARND 2-3Z THE INSTABILITY TO GREATLY DIMINISH.
AT THIS TIME WILL HOLD ONTO THE SLIGHT CHC OF TSRA WORDING THRU 3Z.
ACROSS THE NORTH...THEN LINGER THE TSRA WORDING THRU 06Z FOR THE
SOUTHEAST CWFA.

EARLIER THINKING WAS THAT THIS BOUNDARY WOULD END UP BEING A BACK
DOOR COLD FRONT...AND THIS APPEARS TO BE THE CASE BASED ON CURRENT
CONDS TO THE NORTH. CLOUD COVER SHUD BE SLOWLY THINNING OVERNIGHT TO
A P-CLOUDY SKY...WITH WINDS TURNING NORTHERLY POST FRONTAL PASSAGE.
THIS WILL USHER IN MUCH COOLER AIR AND ALLOW TEMPS TO EASILY RADIATE
INTO THE MID/UPR 50S.

CONFIDENCE IN TEMPERATURES...HIGH.
CONFIDENCE IN PRECIPITATION/THUNDERSTORMS...LOW/MEDIUM.

TUESDAY THROUGH WEDNESDAY...
INITIAL GLANCE IS THAT TUE WOULD BE DRY...HOWEVER THE CONCERN IS ON
THE SOUTHEAST DIVING 500MB VORT THAT WILL BE ARRIVING ACROSS THE
WESTERN CWFA MID/LATE MORNING AND PIVOTING EAST BY THE MID-AFTERNOON
HOURS. THIS MAY PROVIDE ENOUGH LIFT...COUPLED WITH DIURNAL CUMULUS
TUE...AND SOME MOISTURE FROM THE BOUNDARY TO ALLOW A FEW
THUNDERSTORMS TO DEVELOP. WITH TEMPS ALOFT STEADILY COOLING ACROSS
THE CWFA...LAPSE RATES WILL STEEPEN AND A FEW STRONGER STORMS COULD
EASILY PRODUCE SOME PEA SIZE HAIL...BRIEF WIND GUSTS AND HEAVY
DOWNPOURS. THE FOCUS APPEARS TO BE ALONG AND SOUTH OF A ROCKFORD TO
BENTON COUNTY LINE.

OTHERWISE ANTI-CYCLONIC FLOW WILL CONTINUE TO SETTLE INTO THE GREAT
LAKES REGION...AND KEEP A NORTHEAST FLOW AT THE SFC. THIS WILL
EASILY AID IN THE MUCH COOLER MARINE ENVIRONMENT ADVECTING INLAND
ACROSS THE CWFA AND KEEP SFC TEMPS IN THE LOW/MID 70S...EXCEPT THE
FAR SOUTH/SOUTHWEST WHERE TEMPS MAY STILL TOUCH 80 DEG IN THE AFTN.
LOCATIONS IMMEDIATELY ADJACENT TO LAKE MICHIGAN MAY HAVE TEMPS
REMAIN IN THE MID 60S TUE.

OVERNIGHT TEMPS WILL BE MUCH COOLER IN THE LOW/MID 50S. A FEW
LOCATIONS ALONG AND NORTH OF A ROCKFORD...AURORA...WAUKEGAN LINE MAY
HAVE TEMPS IN THE UPR 40S EARLY WED MORNING. THEN HIGH PRESSURE
BEGINS TO DRIFT EAST. WHILE WINDS WILL BE MORE EASTERLY OFF OF THE
LAKE...TEMPS WILL BE SLIGHTLY WARMER WED AFTN IN THE UPR 70S TO LOW
80S. THE EXCEPTION WILL BE AREAS ADJACENT TO LAKE MICHIGAN...WHERE
TEMPS WILL LIKELY REMAIN IN THE 60S TO LOW 70S.

CONFIDENCE...HIGH.

THURSDAY THROUGH SUNDAY...
ENSEMBLES CONTINUES TO POINT TOWARDS A PATTERN CHANGE FOR THE END OF
THE WEEK INTO THE WEEKEND. MANY GUIDANCE MEMBERS ARE IN AGREEMENT
THAT THE 500MB TROUGH OVER THE GREAT LAKES REGION WILL PIVOT EAST
THUR...WITH A STRENGTHENING MID-LVL RIDGE ACROSS THE CENTRAL PLAINS
REPLACING THE DEPARTING TROUGH FRI. THE RIDGE DOES APPEAR TO FLATTEN
SLIGHTLY...WHICH MAY BE AN INDICATION THAT A SLIGHTLY ACTIVE PERIOD
MAY ACCOMPANY THE STEADY WARMING TREND. 850MB THERMAL RIDGE
CONTINUES TO BE RATHER WARM FOR THE WEEKEND...WITH TEMPS GENERALLY
AROUND 20-22 DEG C. THE EC/GEM HAVE TAKEN A SLIGHTLY COOLER APPROACH
WITH 18-20 DEG C...HOWEVER THE OVERALL THEME IS THAT TEMPS WILL BE
STEADILY WARMING. THE WILDCARD FOR MAX TEMPS SAT/SUN/MON...WILL BE
LLVL MOISTURE AND CLOUD COVER. GUIDANCE CONTINUES TO SUGGEST DEW
POINTS WILL GENERALLY BE AROUND 70 DEG. THIS MAY SLOW THE DIURNAL
CURVE FOR THE WEEKEND...HOWEVER TEMPS SHUD EASILY STILL WARM INTO
THE UPR 80S TO POSSIBLY LOWER 90S. AS A RESULT HAVE NUDGED TEMPS
WARMER THAN GUIDANCE FOR THE UPCOMING WEEKEND.

CONFIDENCE IN TEMPERATURES...MEDIUM/HIGH.
CONFIDENCE IN PRECIPITATION/THUNDERSTORMS...MEDIUM.

.AVIATION...

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

* GUSTY WESTERLY WINDS THIS AFTERNOON.
* WIND SHIFT TO THE NORTHEAST EARLY EVENING.
* CHANCE OF SHRA...POSSIBLY AN ISOLATED TSRA...LATE THIS AFTERNOON
  OR EARLY THIS EVENING.
* POSSIBLE LOW CIGS EARLY TUESDAY. CMS

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

A COLD FRONT EXTENDING ACROSS NORTHERN WI AND NORTHERN LAKE
MICHIGAN WILL MOVE SOUTH THIS AFTERNOON ARRIVING INTO NORTHEAST IL
EARLY THIS EVENING. A LAKE BREEZE HAS ALREADY FORMED ACROSS THE
SOUTHEAST SHORE OF WISCONSIN AND THIS WILL NEED TO BE MONITORED
FOR A FASTER PUSH TO THE SOUTHWEST AS THE COLD FRONT CATCHES UP TO
THIS BOUNDARY. WESTERLY WINDS WILL SHIFT TO THE NORTHEAST ONCE THE
FRONT MOVES THROUGH THE TERMINALS EARLY THIS EVENING. NORTHEAST
WINDS WILL THEN PREVAIL THROUGH THE REST OF THE PERIOD. SOME GUSTS
ARE POSSIBLE THIS AFTERNOON BUT SHOULD REMAIN LESS THAN 20 KTS.

SHORT TERM/HI RES GUIDANCE CONTINUES TO SUGGEST RATHER SPARSE
COVERAGE FOR ANY SHRA OR TSRA ACTIVITY THIS AFTERNOON INTO THIS
EVENING. MOST AREAS WILL PROBABLY STAY DRY BUT WILL LEAVE VICINITY
MENTION IN THIS FORECAST. ANY ACTIVITY THAT DOES DEVELOP SHOULD
QUICKLY PUSH SOUTHEAST AND AWAY FROM THE TERMINALS BY MID EVENING.

CIGS EXPECTED TO REMAIN VFR THROUGH THE PERIOD. HOWEVER...THERE IS
A CHANCE OF LOWER CIGS...POSSIBLY IFR...LATE TONIGHT INTO TUESDAY
MORNING AS THE COLDER AIR RUNS INTO THE MORE MOIST LOW LEVELS. IN
ADDITION...AN AREA OF LOW CLOUDS/POSSIBLY FOG OVER NORTHERN LAKE
MICHIGAN MAY CONTINUE MOVING SOUTH ACROSS THE LAKE INTO TONIGHT.
APPEARS THE BEST CHANCE OF ANY LOWER CIGS WOULD BE NEAR THE LAKE
AND POSSIBLY AFFECTING GYY. CONFIDENCE TOO LOW FOR EVEN FEW/SCT
MENTION BUT WILL NEED TO MONITOR THIS WITH LATER FORECASTS. CMS

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

* HIGH FOR A WIND SHIFT TO THE NORTHEAST...MEDIUM FOR TIMING AND
  SPECIFIC DIRECTION/SPEEDS.
* LOW FOR SHRA/TSRA.
* LOW FOR LOWER CIGS EARLY TUESDAY. CMS

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

TUESDAY NIGHT THROUGH FRIDAY...VFR.
FRIDAY NIGHT THROUGH SUNDAY...PERIODIC CHANCES FOR THUNDERSTORMS.

.MARINE...
245 PM CDT

A STRETCH OF RELATIVELY QUIET WEATHER IS STILL IN THE FORECAST
FOR LAKE MICHIGAN OVER MUCH OF THE UPCOMING WEAK. A TROUGH OF LOW
PRESSURE AND AN ASSOCIATED WEAK COLD FRONT...EXTEND FROM NORTHERN
MAINE WEST THROUGH CENTRAL LAKE MICHIGAN. AS THE LOW MOVES OFF TO
THE EAST...THE FRONT WILL CONTINUE TO MOVE SOUTH DOWN THE
LAKE...REACHING THE SOUTHERN TIP OF THE LAKE BY LATE THIS EVENING.
WINDS WILL SHIFT TO NORTHERLY BEHIND THE FRONT...WITH OCCASIONAL
GUSTS TO 25 KT TONIGHT. HIGH PRESSURE OVER THE NORTHERN PLAINS
WILL SPREAD EAST ACROSS THE GREAT LAKES LATE TONIGHT AND
TOMORROW...WITH HIGH PRESSURE REMAINING THE DOMINANT FEATURE OVER
THE LAKE THROUGH WEDNESDAY NIGHT WHEN THE HIGH WILL BEGIN TO SLIDE
OFF TO THE EAST. IN THE MEAN TIME...LOW PRESSURE DEVELOPING OVER
THE NORTHERN ROCKIES WEDNESDAY NIGHT AND WILL MOVE OVER THE
NORTHERN PLAINS BY FRIDAY MORNING. WITH THE HIGH PRESSURE TO THE
EAST AND THE DEVELOPING TROUGH TO THE WEST...WINDS WILL BECOME
SOUTHERLY BY WEDNESDAY OR WEDNESDAY NIGHT...THROUGH THE WEEKEND.
