...BEACH HAZARDS STATEMENT REMAINS IN EFFECT THROUGH THIS
EVENING...

* HIGH WAVE ACTION AND DANGEROUS SWIMMING CONDITIONS EXPECTED.

* FORECAST WAVE HEIGHTS...4 TO 6 FEET.

* STRONG RIP CURRENTS AND STRUCTURAL CURRENTS EXPECTED.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

HIGH WAVE ACTION MAKES SWIMMING DIFFICULT AND CAN TIRE EVEN A
STRONG SWIMMER QUICKLY.

RIP CURRENTS ARE POWERFUL CHANNELS OF WATER FLOWING QUICKLY AWAY
FROM SHORE...WHICH OCCUR MOST OFTEN AT LOW SPOTS OR BREAKS IN
SANDBARS. STRUCTURAL CURRENTS FORM ALONG PIERS WHERE LONGSHORE
CURRENTS AND WAVE ACTION FLOW INTO THE STRUCTURE. RIP CURRENTS
AND STRUCTURAL CURRENTS CAN SWEEP YOU INTO DEEPER WATER.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
306 PM CDT FRI SEP 5 2014

.DISCUSSION...
1142 AM CDT

COLD FRONT IS MOVING THROUGH NORTHWESTERN PORTIONS OF THE CWA LATE
THIS MORNING AND SHOULD CONTINUE TO MAKE STEADY PROGRESS SOUTHEAST
ACROSS THE AREA THIS AFTERNOON. DEVELOPING PRESSURE FALLS OVER
IOWA IN ADVANCE OF SHORTWAVE TROUGH OVER NE KS/SE NE WILL PROBABLY
RESULT IN FRONT SLOWING DOWN A BIT THIS AFTERNOON. GOES EAST IS IN
RAPID SCAN MODE THIS AFTERNOON AND IS NICELY SHOWING SOME
ENHANCEMENT TO THE CUMULUS FIELD RIGHT ALONG THE IMMEDIATE FRONTAL
BOUNDARY. IN GENERAL THE CUMULUS FIELD ON SATELLITE AND OUT THE
WINDOW LOOKS VERY MUSHY AND LACKING VERTICAL GROWTH...LIKELY DUE
IN LARGE PART TO THE VERY FORMIDABLE CAP EVIDENT ON DVN/ILX MORNING
SOUNDINGS AND STILL PRESENT IN RECENT ACARS SOUNDINGS OUT OF ORD
AND MDW. CONTINUED HEATING AND DESTABILIZATION OF THE BOUNDARY
LAYER ALONG WITH FORCED ASCENT ALONG THE FRONT SHOULD EVENTUALLY
CAUSE CAP TO BUST...BUT LIKELY NOT UNTIL THE FRONT IS AT LEAST TO
A CHICAGO TO PERU LINE IF NOT FARTHER SOUTHEAST. WILL BE REWORKING
POP GRIDS TO BETTER REFLECT THIS LINE OF THINKING...INCLUDING VERY
LITTLE THREAT OF PRECIP OVER NORTHWEST CWA AND STEADILY DECREASING
CHANCE FROM THE NORTHWEST SPREADING ACROSS THE AREA THIS
AFTERNOON. POST FRONT RAIN STILL A DISTINCT POSSIBILITY THIS
EVENING INTO TONIGHT AS AFOREMENTIONED KS/NE SHORTWAVE TRACKS
NORTHEAST INTO THE REGION.

IZZI

.MEDIUM AND LONG TERM DISCUSSION...
305 PM CDT...

FOR THE REMAINDER OF THE SHORT TERM...SATURDAY AND SUNDAY...THE
SURFACE COLD FRONT SHOULD PUSH SOUTHEAST OF THE CWA THROUGH THE OHIO
VALLEY.  HOWEVER...GIVEN THAT THE BULK OF THE PCPN SHOULD BE ALONG
AND BEHIND THE BOUNDARY...THERE WILL LIKELY BE SOME LINGERING
SHOWERS AND PERHAPS AN ISOLATED THUNDERSTORM OVER THE FAR
SOUTHEASTERN PORTION OF THE CWA...MAINLY AROUND BENTON COUNTY...
INDIANA.  THROUGH THE DAY ON SATURDAY...HIGH PRESSURE WILL SPREAD
FROM THE CENTRAL PLAINS...ACROSS THE MIDDLE MISSISSIPPI VALLEY AND
INTO THE MIDWEST.  FOLLOWING THE FROPA AND AS THE HIGH SPREADS
ACROSS THE REGION...MOISTURE WILL DIMINISH MARKEDLY...WITH DEWPOINTS
DROPPING THROUGH THE 50S ON SATURDAY AND EVEN INTO THE UPPER 40S BY
SUNDAY.  TEMPERATURES ON SATURDAY WILL BE AT LEAST 10 DEGREES LOWER
THAN ON FRIDAY...ONLY IN THE LOWER 70S.  UNDER FULL SUNSHINE AND
WITH LOW DEWPOINTS...TEMPERATURES ON SUNDAY SHOULD BE ABLE TO
REBOUND BACK INTO THE MIDDLE TO UPPER 70S.  SO AFTER A LITTLE PCPN
OVER THE FAR SERN PORTION OF THE CWA SATURDAY MORNING...THE
REMAINDER OF THE WEEKEND SHOULD BE QUITE PLEASANT.

FOR THE LONGER TERM...FROM MONDAY THROUGH FRIDAY...EXPECT MONDAY TO
START OUT COOL AND DRY WITH LOWS IN THE LOWER 50S.  HOWEVER...
ANOTHER SYSTEM IS EXPECTED TO TAKE SHAPE OVER THE CENTRAL PLAINS.
AS THE HIGH SHIFTS OFF TO THE EAST AND LOW PRESSURE DEVELOPS OVER
THE PLAINS...A RETURN FLOW OF MOISTURE WILL SET UP.  THROUGH THE
DAY...INCREASING WARM/MOIST ADVECTION WILL INCREASE AS A WARM FRONT
ALSO LIFTS NORTH TROUGH THE REGION.  EXPECT THAT THE NEXT ROUND OF
PCPN SHOULD SPREAD INTO THE WRN PORTIONS OF THE CWA BY MONDAY
EVENING AND CONTINUE TO SPREAD EAST ACROSS THE REMAINDER OF THE CWA
THROUGH MONDAY NIGHT AND INTO TUESDAY MORNING.  THE FORECAST PICTURE
BECOMES A BIT MORE MUDDLED INTO MID WEEK AS THE LARGER SCALE MODELS
BEGIN TO DIVERGE IN THEIR SOLUTIONS...WHICH WILL HAVE A BIG IMPACT
ON THE SENSIBLE WEATHER FORECAST.  THE ECMWF WANTS TO DEVELOP A
DEEPER LOW IN ASSOCIATION WITH A NRN STREAM SHORT WAVE WHILE THE GFS
IS QUICKER AND WEAKER.  SINCE THE UPPER LEVEL PATTERN IS EXPECTED TO
REMAIN VERY CLOSE TO ZONAL...WITH AN UPPER RIDGE ACROSS THE SRN
CONUS ANS AND VERY BROAD TROUGHING OVER THE NRN CONUS...AND THE
FASTER WLYS ACROSS THE NRN PLAINS/GREAT LAKES REGION...HAVE TRENDED
CLOSER TO THE FASTER GFS SOLUTION AS THE ZONAL FLOW PATTERN ALOFT
WOULD FAVOR A FASTER SOLUTION.  HOWEVER...THE CAVEAT HERE IS THAT IN
FAST...ZONAL FLOW...FORECAST ERRORS CAN MAGNIFY QUICKLY...
PARTICULARLY IN THE TIMING OF THE SYSTEM...SO...EVEN THOUGH A FASTER
SOLUTION WOULD MAKE SENSE...THE TIMING UNCERTAINTIES ASSOCIATED WITH
FAST ZONAL FLOW ALOFT INTRODUCES LOWER CONFIDENCE IN THE END
PRODUCTS.  BY FRIDAY...AT THE END OF THE FORECAST PERIOD...THE
LONGER RANGE MODELS WANT TO CARVE OUT A SHARPER TROUGH ALOFT AND
BRING MUCH COOLER AIR INTO THE REGION.  THE GFS IS ADVERTISING HIGH
TEMPS ON FRIDAY ONLY IN THE LOWER TO MIDDLE 50S.  THE OLD 00Z RUN OF
THE ECMWF HAD ALSO BEEN INDICATING HIGHS ON FRIDAY ONLY IN THE LOWER
TO MIDDLE 50S...BUT THE NEW 12Z HAS BACKED OFF ON THIS A BIT AND IS
NOW INDICATING HIGHS IN THE UPPER 50S TO LOWER 60S.  AT THAT TIME
RANGE...THE MOS BASED PRODUCTS ARE LIKELY TRENDING TOO CLOSE TO
CLIMATOLOGY...WITH HIGHS IN THE MIDDLE TO UPPER 60S.  SO...HAVE
TRENDED THE FORECAST MAX TEMPS FOR NEXT FRIDAY IN THE LOWER
60S...BUT IT WILL BE INTERESTING TO SEE HOW THIS PLAYS OUT AND IF
THE REGIONS SEES THE FIRST SHOT OF AUTUMNAL WEATHER.

.AVIATION...

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

* ISOLD TSRA THRU EARLY/MID AFTERNOON
* MORE WIDESPREAD SHRA/ISOLD TSRA DEVELOP THIS EVENING CONTINUE
  INTO OVERNIGHT
* WIND SHIFT TO NORTHEAST SATURDAY AFTERNOON

IZZI

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

COLD FRONT WILL MOVE ACROSS CHICAGO AREA TERMINALS THIS AFTERNOON
RESULTING IN WIND SHIFT TO NORTHWEST. LINE OF STRONG/SEVERE TSRA
LIKELY TO ERUPT ALONG THIS FRONT SOUTHEAST OF THE TERMINALS LATE
THIS AFTERNOON...HOWEVER FAIRLY STRONG UPPER LEVEL DISTURBANCE
OVER SOUTHWEST IOWA IS TRACKING ENE TOWARD THE REGION. ALREADY
SEEING SCTD TSRA DEVELOP OVER NW IL IN ADVANCE OF THIS FEATURE AND
EXPECT MORE WIDESPREAD SHRA/ISOLD TSRA OVER SOUTHWEST IOWA WEST
INTO THE PLAINS TO OVERSPREAD THE REGION EARLY THIS EVENING AND
PROBABLY LINGER INTO THE OVERNIGHT HOURS. TSRA CHANCES LOOK
HIGHEST EARLY THIS EVENING WITH PRECIP LIKELY TRENDING MORE TOWARD
RAIN/SHOWER ACTIVITY LATE IN THE EVENING INTO THE OVERNIGHT. SOME
PERIODIC MVFR CIGS ARE POSSIBLE THIS AFTERNOON BUT AS DRIER LOW
LEVEL AIR MASS ADVECTS INTO THE AREA WOULD ANTICIPATE A TREND
TOWARD MORE VFR CIGS WITH THE RAIN THIS EVENING INTO TONIGHT. RAIN
SHOULD SHIFT SOUTHEAST OF THE TERMINALS LATE TONIGHT AND VFR
CONDITIONS ARE EXPECTED SATURDAY. NORTHWEST WINDS EXPECTED BEHIND
FRONT THIS AFTERNOON...THOUGH PRESSURE FALLS IN ADVANCE OF THE
DISTURBANCE OVER IOWA SHOULD RESULT IN A MORE STRAIGHT NORTHERLY
WIND FOR A TIME LATE THIS AFTERNOON AND EARLY THIS EVENING WHICH
COULD POTENTIALLY RESULT IN A LAKE BREEZE DEVELOPING INTO
NORTHEAST ILLINOIS. FOR NOW KEPT WINDS NORTHWEST...BUT WILL
MONITOR OBSERVATIONAL TRENDS FOR POSSIBLE INCLUSION OF A PERIOD OF
NE WINDS THIS EVENING. NW/NNW WINDS OVERNIGHT INTO SAT MORNING
WILL LIKELY SHIFT TO NORTHEAST SATURDAY AFTERNOON WITH LAKE
BREEZE PASSAGE.

IZZI

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

.MARINE...
229 PM CDT

WINDS WILL TURN NORTHWEST THIS EVENING AND THEN NORTH TONIGHT AND
TOMORROW BEHIND A PASSING COLD FRONT. WARM WATER AND COOL AIR WILL
ALLOW WINDS TO MIX DOWN EFFICIENTLY BUT THE GRADIENT IS NOT
ESPECIALLY STRONG SO DO NOT ANTICIPATE EXCESSIVE WAVE GROWTH OR
ANYTHING APPROACHING GALES EXCEPT FOR GUSTS NEAR STRONG STORMS
THIS EVENING. TOMORROW AFTERNOON THE NORTH WINDS BEGIN TO BACK
WEST AGAIN WHICH WILL ALLOW WAVE GROWTH TO BEGIN TAPERING OFF LATE
IN THE DAY. ANOTHER WEAKER TROUGH OR FRONT CROSSES THE LAKE
SATURDAY NIGHT...SO WINDS WILL BE VARIABLE FROM SOUTHWEST AHEAD OF
IT TO NORTHWEST BEHIND IT...BUT HIGH PRESSURE AND QUIET WEATHER
WILL BE THE MAIN STORY FOR THE OPEN WATERS THIS WEEKEND AFTER THIS
EVENING AND TONIGHT. IN THE NEARSHORE THERE WILL BE A PERIOD LATE
TONIGHT AND TOMORROW MORNING WHERE WAVES AND WINDS IN THE INDIANA
NEARSHORE WILL LIKELY SUPPORT SMALL CRAFT ADVISORY CONDITIONS.

   LOCALLY DAMAGING WINDS TO AROUND 60 MPH.
   HAIL UP TO THE SIZE OF QUARTERS.
   FREQUENT CLOUD TO GROUND LIGHTNING.
