AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
300 PM CDT THU JUL 19 2012

.DISCUSSION...
334 AM CDT

MAIN FORECAST CONCERNS CONTINUE TO BE PRECIP CHANCES AND
TEMPERATURES TODAY FOLLOWED BY POTENTIAL FOR LAKE EFFECT CLOUDS AND
MAYBE EVEN SOME LIGHT SPRINKLES/RAIN TONIGHT. EARLY MORNING WATER
VAPOR IMAGERY SHOWS AN UPPER TROUGH OVER QUEBEC WITH A TROUGH AXIS
EXTENDING ALL THE WAY INTO THE SOUTHEAST U.S. AN UPPER SHORTWAVE IS
CURRENTLY MOVING EASTWARD ACROSS WISCONSIN AND FAR EASTERN IOWA WITH
AN UPPER RIDGE MOVING ACROSS THE NORTHERN PLAINS. ANOTHER UPPER
TROUGH IS MOVING EASTWARD ACROSS NORTHERN ALBERTA AND MANITOBA WITH
A CLOSED UPPER LOW PARKED OVER THE WESTERN OREGON/CALIFORNIA BORDER.
AT THE SURFACE...A COOL FRONTAL BOUNDARY EXTENDS FROM NORTHWEST
MISSOURI EASTWARD ACROSS THE SOUTHERN CWA AND ACROSS NORTHERN INDIANA
WITH A CLOSED SURFACE LOW NEAR MUSCATINE IOWA AT 08Z.

TODAY...RATHER TRICKY FORECAST TODAY WITH THE FRONTAL BOUNDARY IN
THE AREA...THE SOUTHEAST IOWA SURFACE LOW MOVING EASTWARD...AND AN
UPPER TROUGH AXIS PASSING BY. CONVECTION CONTINUES TO MARCH EASTWARD
AHEAD OF THE UPPER TROUGH AXIS WHICH BASED ON WATER VAPOR AND
REGIONAL VAD WIND PROFILES IS SHOWN TO STILL BE WEST OF THE LOCAL
AREA BUT MAKING STEADY PROGRESS TO THE EAST. BULK OF THE CONVECTION
WILL BE THROUGH THE AREA IN THE NEXT FEW HOURS THOUGH SOME SPOTTY
ACTIVITY CONTINUES TO POP UP ON THE WESTERN FLANK. THE SURFACE LOW
WILL MOVE EASTWARD THIS MORNING AND IS EXPECTED TO BE ACROSS
NORTHWEST/WEST-CENTRAL INDIANA BY 18Z OR SO WHICH WILL RESULT IN
NORTH TO NORTHEAST WINDS ACROSS MOST OF THE CWA BY EARLY AFTERNOON.
UNTIL THE LOW IS CLEAR OF THE AREA THERE WILL BE AT LEAST A LOW
CHANCE FOR NEW CONVECTION AHEAD OF IT AND THE APPROACHING COLD
FRONT. BUT HAVE A HARD TIME SEEING MUCH COVERAGE GIVEN THE LESS
FAVORABLE TIME OF DAY AND THE ABUNDANCE OF PREVIOUS CONVECTION WHICH
HAS MOVED ACROSS THE AREA THUS FAR. GUIDANCE DOES ALSO SHOW A WEAK
INVERTED TROUGH EXTENDING TO THE NORTHWEST OF THE LOW THIS AFTERNOON
WHICH RESULTS IN A RIBBON OF INSTABILITY LINGERING ACROSS THE AREA
EARLY THIS AFTERNOON DESPITE THE PASSAGE OF THE MAIN LOW
CIRCULATION.  HOWEVER...TIME HEIGHT SECTIONS SHOW SUBSIDENCE
BUILDING IN BEHIND THE UPPER TROUGH AXIS THIS AFTERNOON SO IT LOOKS
TO BE DIFFICULT TO GET MORE CONVECTION GOING THIS AFTERNOON. WILL
CARRY SLIGHT AND LOW CHANCE POPS THIS MORNING WITH THE HIGHEST
VALUES AHEAD OF THE LOW OVER THE SOUTHEASTERN CWA...WITH A SLIGHTLY
HIGHER CHANCE SOUTHEAST EARLY THIS AFTERNOON IMMEDIATELY AHEAD OF
THE COLD FRONT. THERE IS AT LEAST A LOW SEVERE THREAT WITH NEW STORM
DEVELOPMENT AHEAD OF THE LOW/FRONT INTO EARLY AFTERNOON. TEMPS WILL
BE ANOTHER CHALLENGE WITH LOW-MID LEVEL THERMAL AXIS STILL OVERHEAD
TO START THE DAY. SATELLITE SHOWS LITTLE IN THE WAY OF CLOUD COVER
BEHIND THE CURRENT CONVECTION SO A WINDOW OF DECENT SUNSHINE IS
POSSIBLE THIS MORNING. TEMPS LOOK TO REBOUND INTO THE 90S ACROSS
MUCH OF THE SOUTHERN CWA AND MAY TAG 90 ACROSS MOST OF THE AREA
BEFORE NORTH TO NORTHEAST WINDS HELP TO COOL THINGS THIS AFTERNOON.
WITH DEWPOINTS AROUND 70 AND HIGHS IN THE MID 90S SOUTH...HEAT
INDICES LOOK TO JUST TOP 100 DEGREES FOR A SHORT TIME AROUND MIDDAY
FAR SOUTH. OVERALL CONFIDENCE IN DETAILS IS SOMEWHAT LIMITED BUT
HAVE BETTER CONFIDENCE IN OVERALL TRENDS THROUGH THE DAY.

TONIGHT...THINGS REMAIN INTERESTING TONIGHT AS THE UPPER TROUGH
PUSHES TO THE EAST WITH A CLOSED H85 CIRCULATION FOLLOWING SUIT. LOW
LEVEL MOISTURE WRAPS AROUND THE WESTERN SIDE OF THE SYSTEM WITH A
SURGE OF MUCH COOLER AIR SPREADING SOUTHWARD. IT IS POSSIBLE SOME
SHRA/TSRA ACTIVITY COULD LINGER EAST THIS EVENING AS THE SYSTEM
SLOWLY DEPARTS. OTHERWISE... H85 TEMPS LOOK TO COOL TO AS LOW AS 12C
LATE THIS EVENING. WITH THE VERY WARM LAKE WATER RUNNING 24-26C THIS
YIELDS A LAKE TO H85 DELTA T OF 12-14C. WITH FORECAST SOUNDINGS
SHOWING GOOD MOISTURE IN THE FIRST 4000-6000 FT ALONG WITH AN
INVERSION THAT MAY BE AS HIGH AS 5000-6000 FT ABOVE A FAIRLY
ISOTHERMAL LAYER...LAKE EFFECT CLOUD COVER LOOKS LIKE A GOOD BET
FROM THIS EVENING THROUGH THE OVERNIGHT. EVALUATED THE POTENTIAL FOR
SHOWER ACTIVITY AS WELL BUT INVERSION HEIGHTS...ASSUMING THEY REACH
THE ABOVE LEVELS...ARE A BIT ON THE LOW SIDE. WILL LEAVE POPS OUT
FOR NOW BUT THIS WILL BE SOMETHING TO MONITOR.

FRIDAY THROUGH SUNDAY...THE UPPER TROUGH AXIS WILL EXTEND FROM
EASTERN LAKE ERIE SOUTHWESTWARD INTO TENNESSEE BY MIDDAY FRIDAY WITH
THE SURFACE LOW/FRONT EXPECTED TO EXTEND FROM SOUTHEASTERN OHIO INTO
THE LOWER MISSISSIPPI RIVER VALLEY. HIGH PRESSURE WILL SPREAD IN
FROM THE NORTH KEEPING NORTH TO NORTHEAST WINDS IN PLACE WITH SPEEDS
EASING DURING THE AFTERNOON. TEMPERATURES WILL BE MUCH MORE PLEASANT
WITH HIGHS EXPECT AROUND 80 NEAR LAKE MICHIGAN CREEPING UP TO THE
MID 80S ACROSS THE FAR WEST AND SOUTH WITH A FEW UPPER 80S POSSIBLE
AS WELL. AM A LITTLE CONCERNED THAT THESE NUMBERS MAY BE A BIT WARM
GIVEN THE PERSISTENT NORTHEASTERLY FLOW BUT PROVIDED EXPECTED
MORNING CLOUD COVER DISSIPATES AS EXPECTED THEN ENOUGH WARMING
SHOULD OCCUR. THE CENTRAL U.S. RIDGE WILL START TO FLATTEN AND
BROADEN OVER THE WEEKEND WITH THE MAIN BELT OF ACTIVE FLOW REMAINING
ALONG THE U.S./CANADIAN BORDER BUT THE FLOW OVERHEAD REMAINS
SLIGHTLY NORTHWESTERLY WITH WEAK SHORTWAVES EXPECTED TO TRAVERSE IT.
TOUGH TO TIME THESE AND TO EVEN DETERMINE HOW FAR SOUTH THEIR
INFLUENCE WILL BE WITH THE AREA BEING ON THE EDGE OF THE MORE
ORGANIZED FLOW BUT THERE IS SOME POTENTIAL FOR SOME SPOTTY PRECIP
ACTIVITY IF THESE WAVES MOVE CLOSE ENOUGH TO THE AREA. NOT REALLY
CONFIDENT IN MUCH PRECIP OCCURRING OVER THE WEEKEND BUT SUNDAY AND
SUNDAY NIGHT APPEARS TO BE THE FAVORED TIME SO WILL CARRY A SLIGHT
MENTION FAR NORTH FOR NOW. POPS MAY BE NEEDED OVER A LARGER AREA AS
THESE WAVES SHOW THEMSELVES. DO EXPECT A STEADY WARMING TREND
THROUGH THE WEEKEND AS THE MID LEVELS WARM WITH H85 TEMPS BACK INTO
THE 18-20 C RANGE BY SUNDAY. THIS WILL SUPPORT HIGHS AROUND 90
SATURDAY AND IN THE LOW TO MID 90S SUNDAY. WITH A WEAK SURFACE FLOW
LAKE BREEZES WILL BE A GOOD POSSIBILITY KEEPING LAKESHORE AREAS
COOLER...OR ALLOWING THEM TO COOL FROM EARLY HIGHS EACH DAY.

MONDAY AND BEYOND...THE BROAD RIDGING CONTINUES THROUGH THE MIDDLE
OF NEXT WEEK BUT AN UPPER TROUGH IS EXPECTED TO SPREAD SOUTHEASTWARD
FROM HUDSON BAY INTO EASTERN CANADA WHICH WILL HELP ESTABLISH A MID
LEVEL BAROCLINIC ZONE IN THE EASTERN PERIPHERY OF THE RIDGING OVER
THE GREAT LAKES. THIS WILL KEEP A BELT OF ACTIVE FLOW NEAR OR JUST
NORTHEAST OF THE AREA THROUGH THE EARLY PART OF THE WEEK BEFORE
ANOTHER TROUGH MOVES EASTWARD ACROSS SOUTHERN CANADA DURING THE
MIDDLE PART OF THE WEEK. THE WARMING TREND WILL CONTINUE WITH H85
TEMPS LIKELY BACK IN THE 22-24 C RANGE BY MONDAY/TUESDAY BRINGING
BACK THE POTENTIAL FOR MORE 100 DEGREE TEMPS. HOWEVER...THERE DO
LOOK TO BE PERIODIC LOW CHANCES FOR SHOWERS AND STORMS...ESPECIALLY
TOWARDS MIDWEEK BUT ITS TOUGH TO PICK OUT THE BEST PERIODS THIS FAR
OUT.

BEACHLER

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

SFC LOW PRESSURE WAS SLIDING JUST SOUTH OF ORD/MDW...WITH ABUNDANT
CLOUD COVER ACROSS ALL OF NORTHERN ILLINOIS AND NORTHWEST INDIANA
AIRFIELDS. MANY OBS HAVE INDICATED WINDS BECOMING NORTH AT MOST
AIRIFELDS...WHILE A FEW LOCATIONS SUCH AS GYY/IKK HAVE REMAINED SE
WINDS. HOWEVER...MOST GUIDANCE IS POINTING TOWARDS WINDS
SOLIDIFYING FROM THE NORTH PSBLY NORTHEAST OR 350 TO 030 DEG RANGE
OVER THE REMAINDER OF THIS AFTN INTO THE EVE HOURS. WITH NOT MUCH
OF A GRADIENT...WINDS SHUD MAINLY HOVER ARND 6 TO 8 KT THEN
INCREASE TO ARND 10-12 KT OVERNIGHT. GUIDANCE DOES DIFFER
OVERNIGHT WITH RESPECT TO CIGS. WITH THE LACK OF A PUSH OF DRY
AIR...IT APPEARS CIGS SHUD SINK TOWARDS LOW END MVFR PSBLY
REACHING THE THRESHOLD OF IFR CONDS. AT THIS POINT HAVE OPTED TO
HANDLE THIS MENTION AS LOW END MVFR CIGS OR ARND 1500FT AGL DUE TO
THE CONTINUED NE FLOW OF WINDS. THIS MAY ALLOW SOME DRY AIR TO
LIFT THE LOW CLOUDS TO A UNIFORM BKN/OVC DECK AT MVFR CONDS.

GUIDANCE THEN CONTINUES TO KEEP MVFR CIGS THRU DAYBREAK FRI...THEN
BEGINS TRENDING UP AS BETTER MIXING OCCURS FRI. A SOLID PUSH OF
DRY AIR DOES NOT APPEAR TO ARRIVE ACROSS THE AIRFIELDS UNTIL
CLOSER TO MIDDAY PSBLY LINGERING INTO THE EARLY AFTN HOURS...SO
HAVE OPTED TO HOLD ONTO THE BKN DECK UNTIL 18Z.

.MARINE...

300 PM...WEAK LOW PRESSURE OVER EAST CENTRAL ILLINOIS WILL MOVE
EAST TO THE MID ATLANTIC STATES ON FRIDAY AS A RIDGE OF HIGH
PRESSURE BUILDS SOUTHEAST ACROSS THE MIDWEST AND NORTHERN LAKES
TONIGHT. THIS WILL TIGHTEN THE GRADIENT ACROSS LAKE MICHIGAN...
ESPECIALLY THE CENTRAL AND SOUTHERN PART OF THE LAKE WITH
NORTHERLY WINDS INCREASING TO 15-25 KTS. THESE STRONGER WINDS WILL
SLOWLY DIMINISH FROM NORTH TO SOUTH OVERNIGHT INTO FRIDAY. AS THE
RIDGE SHIFTS EAST...WINDS WILL TURN SOUTHERLY FRIDAY NIGHT INTO
SATURDAY. A WEAK COLD FRONT WILL MOVE ACROSS THE NORTHERN PART OF
THE LAKE SATURDAY NIGHT INTO SUNDAY MORNING...THEN WASH OUT AS
WINDS TURN BACK SOUTHERLY SUNDAY AFTERNOON INTO SUNDAY NIGHT.
ANOTHER STRONGER COLD FRONT IS EXPECTED TO MOVE SOUTH ACROSS LAKE
MICHIGAN MONDAY AFTERNOON INTO MONDAY NIGHT. CMS

1105 AM CDT THU JUL 19 2012 /1205 PM EDT THU JUL 19 2012/

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

  WEATHER HAZARDS EXPECTED:

  THUNDERSTORMS...SOME MAY PRODUCE:
    BRIEF HEAVY DOWNPOURS.
    OCCASIONAL WIND GUSTS TO 60 MPH.
    AND FREQUENT LIGHTNING.

  AREAS AFFECTED AND TIMING:

  SCATTERED THUNDERSTORMS WILL BE POSSIBLE ACROSS PORTIONS OF THE
  OUTLOOK AREA THROUGH THIS AFTERNOON GENERALLY SOUTH AND EAST OF
  A LINE FROM VALPARAISO TO PONTIAC. THERE IS ALSO A SLIGHT CHANCE
  THAT A FEW OF THESE STORMS WOULD REACH SEVERE LEVELS...PRODUCING
  STRONG WIND GUSTS. THE THUNDERSTORM POTENTIAL WILL END FROM WEST
  TO EAST THROUGH THE AFTERNOON...AND COMING TO AN END BY SUNSET.

  DISCUSSION:

DECREASING CLOUD COVER FOLLOWING THE PASSAGE OF AN UPPER LEVEL
DISTURBANCE WILL BRING INCREASING INSTABILITY AND THE POTENTIAL
FOR ISOLATED TO SCATTERED THUNDERSTORMS THROUGH THIS AFTERNOON.
THE MOST FAVORED AREA FOR DEVELOPMENT WILL BE SOUTH AND EAST OF A
LINE FROM VALPARAISO TO PONTIAC. GIVEN THE DEGREE OF INSTABILITY
AND INCREASED DEEP LAYER WIND SHEAR...SOME OF THE STORMS THAT CAN
DEVELOP WILL HAVE THE CHANCE TO BECOME SEVERE. THE THREAT FOR
SEVERE STORMS WILL LIKELY DIMINISH FROM WEST TO EAST THROUGH THE
AFTERNOON.

THERE WILL BE AN INCREASED THREAT FOR RIP CURRENTS ALONG THE
ILLINOIS AND INDIANA SHORES THIS AFTERNOON THROUGH LATE TONIGHT.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.

THERE IS A SLIGHT CHANCE FOR THUNDERSTORMS SUNDAY AND SUNDAY
NIGHT NORTH OF INTERSTATE 90. THERE WILL BE CHANCES FOR
THUNDERSTORMS ACROSS THE ENTIRE OUTLOOK AREA FROM MONDAY NIGHT
THROUGH WEDNESDAY.

THERE WILL BE AN INCREASED THREAT FOR RIP CURRENTS ALONG THE
ILLINOIS SHORES THROUGH FRIDAY EVENING AND ALONG THE INDIANA
SHORES THROUGH LATE FRIDAY NIGHT.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED TODAY.
