Flash Flood Warning 11, NWS Chicago, IL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
913 AM CDT MON JUN 15 2015

.SHORT TERM...
348 AM CDT

TODAY AND TONIGHT...

HAVE ELECTED TO ISSUE A FLASH FLOOD ADVISORY FOR THE ENTIRE CWA
THROUGH THIS EVENING...AND FOR AREAS ALONG/SOUTH OF I-80 CORRIDOR
INTO EARLY TUESDAY MORNING.

SURFACE LOW PRESSURE OVER THE UPPER MISSISSIPPI VALLEY WILL MOVE
SLOWLY TO THE EAST TODAY...IN RESPONSE TO PARTIAL PHASING OF
SHEARED MID-LEVEL TROUGH OVER THE REGION AND A STRONGER SHORT WAVE
PROPAGATING ACROSS SOUTHERN CANADA AND THE UPPER MIDWEST. VERY
MOISTURE RICH LOW-MID TROPOSPHERIC AIR MASS REMAINS IN PLACE
BETWEEN HIGH PRESSURE RIDGE OVER THE SOUTHEASTERN STATES AND SLOW
MOVING COLD FRONT TRAILING THE SURFACE LOW...SETTING THE STAGE FOR
ADDITIONAL HEAVY-RAIN PRODUCING THUNDERSTORMS ACROSS THE FORECAST
AREA TODAY INTO TONIGHT. FORECAST SOUNDINGS DEPICT PRECIPITABLE
WATER VALUES OF 1.80-2.00"...WITH CORFIDI VECTORS SUGGESTING
POTENTIAL FOR SLOW FORWARD MOVING AND TRAINING/BACK-BUILDING CELLS
ESPECIALLY LATER TODAY/THIS EVENING. RELATIVELY WARM TEMPS ALOFT
AND POOR MID-LEVEL LAPSE RATES SUGGEST MINIMAL SEVERE THREAT
DESPITE 25-40 KT OF 0-6 KM BULK SHEAR THIS AFTERNOON...MAINLY IN
THE FORM OF ISOLATED DAMAGING WIND GUSTS FROM MULTI-CELL CLUSTERS.
BUT HEAVY RAINFALL IS THE MAIN THREAT...PARTICULARLY THE GROUND
PRETTY MUCH SATURATED FROM REPEATED RAINS OVER THE PAST WEEK OR
SO. AREAS SOUTH OF I-80 ARE ESPECIALLY WATER-LOGGED...WITH 5-8" OF
RAIN IN SOME SPOTS PER 7 DAY RADAR RAINFALL ESTIMATES ACROSS THE
CWA. EVEN AREAS FARTHER NORTH HAVE SEEN 1.5-2.0" FOR THE MOST
PART...WITH THE POTENTIAL FOR FLOODING TO DEVELOP QUICKLY JUST
ABOUT ANYWHERE WITH HIGH-RAINFALL EFFICIENCY STORMS.
RAIN/THUNDERSTORMS SHOULD SLOWLY DIMINISH FROM THE NORTHWEST
TONIGHT AS THE FRONT SLOWLY SAGS SOUTHEAST...BUT MAY CONTINUE IN
LIGHTER FASHION SOUTH OF I-80 AT TIMES INTO TUESDAY AS FRONT
STALLS ACROSS CENTRAL IL/IN AND WEAK SHORT WAVES CONTINUE TO
RIPPLE ALONG THE BAROCLINIC ZONE.

WARM AND HUMID CONDITIONS TODAY DESPITE CLOUD COVER AND PRECIP.
DAYTIME HIGHS EXPECTED TO RANGE FROM AROUND 80 NORTH...TO THE MID
80S IN THE SOUTHEAST ESPECIALLY WITH ANY APPRECIABLE SUN.

.LONG TERM...
401 AM CDT

TUESDAY THROUGH SUNDAY...

COLD FRONT CONTINUES TO SAG ACROSS CENTRAL IL/IN TUESDAY...WHILE
SURFACE HIGH PRESSURE SPREADS FROM THE UPPER MISSISSIPPI VALLEY TO
THE NORTHERN AND WESTERN GREAT LAKES. INDICATIONS ARE THAT A FEW
MINOR AMPLITUDE SHORT WAVES WILL CONTINUE TO RIPPLE ALONG THE
BAROCLINIC ZONE AND PRODUCING PRECIPITATION PERHAPS AS FAR NORTH
AS OUR SOUTHERN CWA COUNTIES GENERALLY SOUTH OF THE KANKAKEE AND
ILLINOIS RIVER VALLEYS. ANOTHER SHORT WAVE IS NOTED PROPAGATING
EASTWARD THROUGH ZONAL FLOW ACROSS THE NORTHERN PLAINS TUESDAY
NIGHT WHICH RESULTS IN DEVELOPMENT OF A SURFACE LOW INTO SOUTHWEST
MINNESOTA 12Z WED. BACKING LOW LEVEL FLOW ACROSS THE
SOUTHERN/CENTRAL PLAINS AND MISSISSIPPI VALLEY BEGINS TO LIFT THE
STALLED FROM BACK NORTH AS A WARM FRONT LATE TUESDAY NIGHT AND
WEDNESDAY...WITH THE POTENTIAL FOR SHOWERS/THUNDERSTORMS TO SPREAD
BACK NORTH ACROSS THE CWA BY EARLY WEDNESDAY.

IN SHORT...THE REMAINDER OF THE WEEK AND WEEKEND APPEAR TO OFFER
MORE POTENTIAL FOR PERIODIC RAINS AS THE FRONT CONTINUES TO WOBBLE
NORTH AND SOUTH ACROSS THE AREA. REMNANTS OF TROPICAL DEPRESSION
#1 CURRENTLY OVER THE GULF OF MEXICO MAY WELL MAKE ITS WAY INTO
THE OHIO VALLEY AND MIDWEST LATE IN THE WEEK. WARM AND HUMID
CONDITIONS WILL ALTERNATE WITH BRIEF PERIODS OF FLOW OFF LAKE
MICHIGAN...WITH TUESDAY AND FRIDAY MOST LIKELY TO FEATURE ONSHORE
FLOW AND COOLER TEMPS ESPECIALLY NEAR THE LAKE AS SURFACE HIGH
PRESSURE SYSTEMS PASS ACROSS THE NORTHERN LAKES. OTHERWISE...MUGGY
80S ARE EXPECTED BY DAY WITH 60S BY NIGHT AWAY FROM LAKE MICHIGAN.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 14Z...

* A SECOND PERIOD OF SOME SHRA WITH SOME NEAR BY OR TEMPORARY TSRA
  AFTER 1530 UTC.

* MULTI-HOUR TSRA WITH TEMPORARY IFR CONDITIONS LIKELY LATE
  AFTERNOON INTO THE EVENING. NUMEROUS TO WIDESPREAD COVERAGE OF
  STORMS IN THE TRACON AREA FAVORED DURING THAT TIME.

* VARIABLE CIGS THIS MORNING WITH TEMPORARY IFR
  POSSIBLE...MAINLY OUTSIDE OF HEAVIER SHRA/TSRA.

* VARIABLE WINDS NEAR TSRA.

* WINDS BECOMING NORTHEAST NEAR SUNRISE TUESDAY WITH POSSIBLE LOW
  CLOUDS.

//DISCUSSION...UPDATED 12Z...

NUMEROUS SHOWERS WITH SCATTERED STORMS WILL CONTINUE TO TRACK
NORTHEAST OVER/NEAR THE TAF SITES THROUGH MID-MORNING. THE SUBTLE
UPPER LEVEL DISTURBANCE HELPING TO AID IN THE COVERAGE OF THESE
WILL MOVE NORTH OF THE AREA BY LATER THIS MORNING AND AN EXPECTED
LULL IN COVERAGE IN SHRA/TSRA IS EXPECTED INTO EARLY AFTERNOON.
THERE STILL WILL LIKELY BE ISOLATED SHRA IN THE AREA...BUT THE
BETTER FOCUS ARRIVES LATER IN THE AFTERNOON.

AREAS OF MVFR AND IFR CIGS ARE SEEN EARLY THIS MORNING BASICALLY
FROM MLI TO ORD AND NORTH. INDIVIDUAL AIRPORTS SEE IMPROVEMENT
WITH THE RAIN SHOWERS...BUT THEN DROP BACK DOWN AFTER THE SHOWERS
BRIEFLY END. SO OVERALL CONFIDENCE ON ANY IFR DURATION IS LOW
ESPECIALLY AT MDW...BUT TEMPORARY IFR CONDITIONS ARE STILL LIKELY
AT ORD FOR AT LEAST ANOTHER HOUR OR TWO AFTER 12Z.

THE WEATHER REGIME FROM MID-AFTERNOON INTO MID-EVENING CONTINUES
TO SUPPORT A MULTI-HOUR TSRA EPISODE DUE TO A SLOW MOVING COLD
FRONT AND UPPER DISTURBANCE SHIFTING INTO A RICHLY TROPICAL AIR
MASS. WHILE SPECIFICS ON EXACT HOURS STILL REMAIN SOMEWHAT LOW
CONFIDENCE...THE MAXIMA IN COVERAGE ACROSS THE ORD/MDW AREA AND
ARRIVAL GATES LOOK TO BE JUST AFTER PEAK HEATING...SO LATE
AFTERNOON INTO EARLY EVENING.

WINDS TURN NORTHWEST BEHIND THE COLD FRONT WHICH LOOKS TO PASS
MID-EVENING OR SO. WINDS WILL THEN TURN OFF OF LAKE MICHIGAN ON
TUESDAY MORNING. A LAGGING DRY AIR PUSH MAY KEEP SOME LOW
VISIBILITY OR CLOUDS AROUND TONIGHT AND INTO EARLY TUESDAY
MORNING.

//ORD AND MDW CONFIDENCE...UPDATED 14Z...

* MED TO HIGH IN ANOTHER PERIOD OF SHRA WITH SOME POSSIBLE TS
  AFTER 1530 UTC THROUGH AROUND 17 UTC.

* HIGH THAT TSRA WILL OCCUR AGAIN AT THE AIRFIELDS SOMETIME
  BETWEEN MID- AFTERNOON AND MID-EVE. MEDIUM-HIGH IN TSRA BEING A
  SEVERAL HOUR DURATION. LOW-MEDIUM ON SPECIFIC WINDOW OF TIME.

* LOW ON SPECIFIC TIMING AND DURATION OF ANY IFR CIGS OUTSIDE OF
  SHRA/TSRA.

* MEDIUM-HIGH ON WINDS REMAINING FROM THE WEST THROUGH THIS
  EVENING APART FROM NEAR STORMS.

* MEDIUM-HIGH IN WIND SHIFT TIMING TO NORTH-NORTHEAST.

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

TUESDAY NIGHT...SLIGHT CHANCE OF SHRA LATE. NORTHEAST WINDS.
WEDNESDAY...CHANCE OF TSRA. SOUTH WINDS.
THURSDAY...CHANCE OF TSRA. WEST WINDS.
FRIDAY...SLIGHT CHANCE OF TSRA. EAST WINDS.
SATURDAY-SUNDAY...CHANCE OF TSRA. SOUTHWEST WINDS.

.MARINE...
148 AM CDT

LIGHT AND VARIABLE WIND FLOW EARLY THIS MORNING SHOULD TURN MORE
SOUTH-SOUTHWEST BY MID-LATE MORNING WITH THE APPROACH OF A WEAK
LOW PRESSURE MOVING ACROSS CENTRAL WISCONSIN. THE CONTINUED MOIST
CONDITIONS SHOULD SUPPORT AREAS OF FOG OVER THE OPEN WATERS. WITH
THE LIGHT OFFSHORE COMPONENT...THINKING IMMEDIATE IL AND IN SHORE
AREAS WILL REMAIN FREE OF THE MOST DENSE FOG TODAY. A COLD FRONT
WILL EVOLVE SOUTHWARD BEHIND THE LOW THIS EVENING...GRADUALLY
TURNING WINDS NORTH. SOME FOG MAY LINGER BEHIND THIS FRONT DUE TO
LIMITED DRY ADVECTION AT FIRST...AND SOME OF THIS COULD SPILL
INTO THE IL AND IN NEARSHORES.

HIGH PRESSURE WILL QUICKLY SCOOT OVER THE LAKE TUESDAY AFTERNOON AND
NIGHT BEFORE ANOTHER LOW MOVES EASTWARD OVER THE LAKE LATER
WEDNESDAY. A WEAK FRONT ASSOCIATED WITH THIS WILL MOVE SOUTHWARD
OVER THE LAKE THURSDAY AND THURSDAY NIGHT. OVERALL THE WIND FLOW
LOOKS TO REMAIN LIGHT WITH POSSIBLE OCCASIONAL PERIODS OF 10-20 KT
FLOW OVER THE OPEN WATERS.
