Damaging Winds in Illinois, July 12, 2014

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
708 PM CDT SAT JUL 12 2014

.MESOSCALE DISCUSSION...
555 PM CDT

LOCAL AREA CONTINUES TO DESTABILIZE EARLY THIS EVENING...ESPECIALLY
ACROSS SOUTHWESTERN COUNTIES IN THE CWA WHERE PARTIAL CLEARING AND
STRONG SOUTHWEST WINDS HAVE ALLOWED TEMPERATURES TO WARM INTO THE
LOWER TO MID 80S WITH DEWPOINTS INTO THE MID 70S. FARTHER NORTH
AND NORTHEAST MORE EXTENSIVE CLOUD COVER HAS HAMPERED
DESTABILIZATION TO SOME DEGREE...HOWEVER 22Z AMDAR SOUNDING OUT OF
ORD PAIRED WITH NAM MOISTURE PROFILES INDICATES AROUND 1000 J/KG
MLCAPE WITH AROUND 100 J/KG MLCIN TO OVERCOME. THIS LINES UP WELL
WITH SPC MESOANALYSIS SHOWING THE CAP OVER THE NORTHEAST CORNER OF
IL WITH OVER 2000 J/KG MLCAPE OVER THE SOUTHWEST WHICH IS MOSTLY
UNCAPPED. SHEARED VORT LOBE IS DRIVING EAST ACROSS MN/IA AND WI
CURRENTLY AND HAS PROVIDED SOME BROAD SCALE ASCENT TO KICK OFF A
FEW THUNDERSTORMS ALONG A FRONTAL BOUNDARY THAT STRETCHES FROM
SOUTH CENTRAL IA TO NEAR THE QUAD CITIES WHERE PWATS HAVE POOLED
TO AROUND 2 INCHES. A CORRIDOR OF 40+ KT 0-6KM SHEAR WILL SUPPORT
ORGANIZED THUNDERSTORMS AS ALREADY EVIDENT BY THE SUPERCELL NORTH
OF THE QUAD CITIES. EXPECT LINE OF STORMS TO CONTINUE TO FILL IN
AS THE EVENING PROGRESSES WITH A STEADY FEED OF MOISTURE INTO THE
REGION AS 40-50 KT LOW LEVEL JET DEVELOPS LATER THIS EVENING
HELPING TO MAINTAIN THUNDERSTORMS THROUGH THE LATE EVENING AND
OVERNIGHT HOURS. AS PREVIOUSLY DISCUSSED...HEAVY RAIN AND STRONG
WINDS STILL APPEAR TO BE THE PRIMARY THREATS THIS EVENING AND
TONIGHT.

.DISCUSSION...
311 PM CDT

THIS AFTERNOON...
THE SURFACE LOW IS OVER NORTHERN MANITOBA AND THE UPPER LEVEL LOW IS
STACKED JUST ABOVE IT.  STILL HAVE MOSTLY CLOUD SKIES WITH A FEW
BREAKS OF SUN AND WE ARE SLOWLY RECOVERING FROM THIS MORNING/S
CONVECTION.  THE 18Z DVN SOUNDING FEATURED 1.7 INCHES OF PWAT AND
AROUND 1500 J/KG OF CAPE. THE SOUNDING ALSO HAD A STOUT CAP AT 850MB
WHICH MATCHES WELL WITH THE LATEST AMDAR SOUNDINGS.  LAPSE RATES TO
950 MB WERE SURPRISINGLY STEEP GIVEN THE THICK CLOUD COVER. WITH THE
CAP IN PLACE AND SLOW RECOVERY NOT EXPECTING MUCH CONVECTIVE
ACTIVITY AHEAD OF THE MAIN LINE OF STORMS. IN GENERAL EXPECTING
CLOUDS TO CONTINUE THIN AND TEMPS RISE INTO THE MID 80S BY LATE THIS
AFTN.  IT WILL CONTINUE TO BE MUGGY AS PWAT VALUES INCREASE TO
AROUND 2 INCHES.

THIS EVENING AND TONIGHT...
AN UPPER LEVEL SHORTWAVE CURRENTLY OVER IOWA WILL MOVE OVER THE CWA
THIS EVENING ADDING FORCING FOR STORMS. A SURFACE LOW IS OVER
NORTHERN MANITOBA AND ITS COLD FRONT STRETCHES FROM NORTHWEST
WISCONSIN THROUGH CENTRAL IOWA.  A LINE OF STORMS WILL FORM ALONG
THE FRONT AND SLOWLY PUSH SOUTH THROUGH THE CWA THIS EVENING AND
OVERNIGHT. 850MB STEERING FLOW WILL BE WEST AT 30-40 KT AHEAD OF THE
LINE BUT ONLY AROUND 15 KT FROM THE NORTH BEHIND THE FRONT. TIMING
DIFFERS BETWEEN THE MODELS BUT THINKING A BLEND OF OUR LOCAL ARW AND
THE RAP LOOK REASONABLE. THE NAM LOOKS TOO FAST WHILE THE HRRR LOOKS
TOO SLOW.

THE LINE MAY PRODUCE SEVERE WIND GUSTS IN EXCESS OF 60 MPH...BUT THE
MAIN CONCERN WILL BE FLASH FLOODING. PWAT VALUES REMAIN HIGH AT
1.7-1.8 INCHES AND VALUES WILL INCREASE TO AROUND 2 INCHES BY THIS
EVENING.  HAVE ISSUED A FLASH FLOOD WATCH FOR THE ENTIRE WARNING
AREA FOR THIS EVENING THROUGH TOMORROW MORNING.  TOTAL RAINFALL FROM
THIS STORM WILL BE IN EXCESS OF 1 INCH. THE HIGHEST TOTALS WILL
LIKELY BE ALONG THE IL/WI STATE LINE WHERE RAINFALL TOTALS WILL
EASILY APPROACH 2 INCHES.  IN ADDITION...SOME AREAS THIS MORNING
FROM COOK COUNTY SOUTH THROUGH PONTIAC AND GIBSON CITY SAW MULTIPLE
INCHES OF RAIN OVERNIGHT INTO THIS MORNING. THESE AREAS WILL BE THE
MOST SUSCEPTIBLE TO FLASH FLOODING AS WATER LEVELS ARE ALREADY
HIGH.

TEMPERATURES WILL QUICKLY FALL BEHIND THE LINE OF STORMS AND LOWS
WILL BE IN THE UPPER 60S TO LOWER 70S.

SUNDAY AND MONDAY...
THE UPPER LEVEL LOW SPLITS SUNDAY NIGHT AND THE FIRST TROUGH AXIS
MOVES THROUGH MONDAY NIGHT.  AT THE SURFACE A SECOND COLD FRONT
MOVES THROUGH SUNDAY AND THEN STALLS OUT JUST SOUTH OF THE CWA
MONDAY MORNING. THE HIGHEST INSTABILITY VALUES WILL BE SOUTH OF I-80
SO ONLY HAVE A CHANCE OF STORMS SOUTH OF I-80. NOT EXPECTING MUCH IN
THE WAY OF PRECIP AT THIS TIME.

A BAND OF SHOWERS AND STORMS MAY FORM SUNDAY NIGHT FIRST ALONG THE
IL/WI STATE LINE AND THEN SPREAD SOUTH AS A VORTICITY STREAMER FROM
THE UPPER LEVEL LOW PUSHES SOUTH THROUGH THE REGION.  THE SHOWERS
MAY PERSIST INTO LATE SUNDAY NIGHT AND BY THEN ONLY EXPECTING
SHOWERS.  CONFIDENCE IS MEDIUM WITH THE STORMS DEVELOPING AND
COVERAGE.

YET ANOTHER COLD FRONT COMES THROUGH MONDAY AND HAVE A CHANCE OF
SHOWERS AND STORMS MONDAY AFTERNOON AND EVENING.  THE BIGGER STORY
WILL BE THE COOL AIR THAT FOLLOWS THE COLD FRONT.  HIGHS ON SUNDAY
WILL BE IN THE LOWER 80S WHILE MONDAY/S HIGHS WILL BE IN THE MID TO
UPPER 70S.  MONDAY NIGHT LOOKS CRISP WITH LOWS IN THE LOWER 50S.

EXTENDED...TUESDAY THROUGH FRIDAY...
THE UPPER LEVEL TROUGH SLOWLY LIFTS NE THROUGH THURSDAY WHILE A
SURFACE HIGH BUILDS OVER THE REGION TUESDAY NIGHT. THE EXTENDED
LOOKS DRY WITH BELOW NORMAL TEMPERATURES.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 00Z...

* SCATTERED TSRA BETWEEN 0130Z-0400Z WITH TSRA LIKELY LATE THIS
  EVE INTO EARLY OVERNIGHT. TEMPORARY IFR VISIBILITY LIKELY WITHIN
  STORMS AND POSSIBLE IFR.

* MVFR CIGS POSSIBLE THROUGHOUT THE NIGHT WITH TEMPORARY IFR
  POSSIBLE DURING THE TSRA.

* SMALL CHANCE FOR SHRA/TSRA LATE SUNDAY AFTERNOON/EARLY SUNDAY
  EVE.

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

A SURFACE WARM FRONT IS DRAPED ACROSS NORTHERN IL...PRETTY NEAR THE
CHICAGO AREA TERMINALS. THIS WILL SERVE AS A FOCUS FOR STORMS AS
THE EVENING PROGRESSES...WITH STORMS LIKELY TO EXPAND EASTWARD
THROUGH MID-EVENING AS AN UPPER DISTURBANCE MOVES OVER THE AREA.
IT STILL REMAINS TRICKY TO TIME THE FIRST STORMS...BUT THE
GREATEST COVERAGE LOOKS TO BE THE TIMES WITH PREVAILING TSRA IN
THE TAFS. DUE TO A SUBSTANTIAL AMOUNT OF MOISTURE...HIGH RAINFALL
RATES AND LOW VISIBILITY...POTENTIALLY TO LIFR...IS TEMPORARILY
EXPECTED.

PATCHY MVFR CIGS HAVE BEEN SEEN ALONG AND NORTH OF THE WARM FRONT
AND THAT SHOULD CONTINUE UNTIL THE STORM ARRIVAL TIME. IN THE WAKE
OF THE STORMS...LINGERING MVFR CIGS MAY PERSIST FOR UP TO SEVERAL
HOURS.

WINDS ARE SOUTH-SOUTHWEST AT MUCH OF THE TAF SITES EARLY THIS
EVE AND THAT SHOULD CONTINUE. AS STORMS MOVE OVER...OF COURSE SOME
VARIABILITY CAN BE EXPECTED. A LARGE WELL-DEFINED COMPLEX OF
STORMS IS NOT EXPECTED...WHICH CAN SOMETIMES RESULT IN A SOUTHEAST
WIND AFTERWARD.

THE INITIAL COOL FRONT WILL MOVE THROUGH OVERNIGHT TURNING WINDS
TO THE NORTHWEST. A SECONDARY STRONGER ONE WILL MOVE THROUGH LATE
IN THE DAY SUNDAY. THIS COULD TRIGGER A FEW SHOWERS OR
STORMS...THOUGH THERE IS LIMITED FORCING.

//ORD AND MDW CONFIDENCE...UPDATED 00Z...

* MEDIUM IN TSRA TIMING. HIGH IN AT LEAST TEMPORARY IFR VISIBILITY
  DURING THE TSRA.

* HIGH IN MVFR CIGS REMAINING 1500 FT OR HIGHER OUTSIDE OF STORMS
  THIS EVE. LOW IN DEPARTURE TIME OF MVFR CIGS LATE TONIGHT/SUNDAY
  MORNING.

* LOW IN ANY SHRA/TSRA SUNDAY AFTERNOON/EARLY SUNDAY EVE.

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

MONDAY...CHANCE OF AFTERNOON TSRA.
TUESDAY...CHANCE OF SHRA.
WEDNESDAY-FRIDAY...VFR LIKELY.

MTF

.MARINE...
423 PM CDT

SOUTHERLY FLOW PERSISTING OVER THE ENTIRE LAKE THIS AFTERNOON AS
HIGH PRESSURE REMAINS SITUATED OVER THE ATLANTIC COAST...AND AS A
TROUGH OF LOW PRESSURE AND ASSOCIATED FRONTAL BOUNDARY ARE JUST
WEST OF THE LAKE. AS THESE SOUTHERLY WINDS BECOME MORE SOUTHWEST
AND THEN EVENTUALLY WEST TONIGHT WITH THE PASSAGE OF THIS
TROUGH...DO EXPECT SPEEDS TO REMAIN IN THE 10 TO 20 KT RANGE.
EXPECTED COMPLEX OF SHOWERS AND THUNDERSTORMS WILL LIKELY PROVIDE
ERRATIC WINDS LATER THIS EVENING AND OVERNIGHT...AS WELL AS THE
POSSIBILITY FOR SLIGHTLY HIGHER SPEEDS. DO EXPECT MORE OF A WEST
NORTHWEST WIND ACROSS THE LAKE ON SUNDAY...AS A SECONDARY
TROUGH/FRONT MOVE SOUTHEAST THROUGH THE GREAT LAKES REGION.
