Damaging Winds in Indiana, July 24, 2010

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
524 PM CDT SAT JUL 24 2010

.DISCUSSION...
342 PM CDT

SEVERAL FORECAST ISSUES REMAIN TODAY...BUT WITH CONDITIONS TO
IMPROVE LATER TONIGHT INTO SUNDAY MORNING.

MANY LOCATIONS IN NORTHERN ILLINOIS STILL RECOVERING FROM THIS
MORNINGS RAINFALL...WITH AREAL FLOOD WARNING STILL ONGOING FROM
THE WINNEBAGO AND OGLE COUNTIES SOUTHEAST INTO COOK COUNTY DUE TO
WIDESPREAD RAINFALL AMOUNTS OF 3 TO 5 INCHES WITH MANY LOCAL
HIGHER AMOUNTS. DID CUT SOME OF THE NORTHERN PART OF THE WARNING
MAINLY MCHENRY AND LAKE COUNTIES...WITH NO FLOODING REPORTED FROM
LOCAL AUTHORITIES. WITH NEXT UPDATE FORTH COMING IN THE NEXT HOUR
OR SO...WILL PROBABLY EXTEND THE AREAL FLOOD WARNING WITH THE IDEA
THAT THIS HEAVY RAINFALL WILL TAKE SOME TIME TO RECEDE. DID DROP
THE FLASH FLOOD WATCH EARLY DUE TO HEAVIEST RAINFALL HAVING
ENDING...AND THE ANTICIPATION THAT ANY RAIN THAT DOES DEVELOP
TODAY WILL NOT PRODUCE ANY FLASH FLOODING.

HEAT ADVISORY ALSO STILL IN EFFECT UNTIL LATER THIS EVENING.
THOUGHT ABOUT CANCELLING THE ADVISORY EARLIER TODAY...DUE TO
ONGOING SHOWERS AND THUNDERSTORMS AND ASSOCIATED CLOUD COVER.
ALTHOUGH DID NOTICE WEAKENING TRENDS WITH CONVECTION AND AN
ERODING CLOUD SHIELD...SO OPTED TO LET IT RIDE. WITH DECENT
SUNSHINE TODAY AND STRONG SOUTHERLY FLOW OUT AHEAD OF MAIN SYSTEM
TO THE NORTHWEST...TEMPERATURES WERE ABLE TO RISE TODAY IN THE
ADVISORY LOCATION WITH LOCATIONS CURRENTLY REPORTING TEMPS IN THE
LOWER 90S. THIS COUPLED WITH DEWPOINTS STILL REACHING THE MID 70S
HAS PROVIDED HEAT INDICES RANGING FROM 100 TO 105. EXPECT THESE
VALUES TO GRADUALLY COME DOWN THIS EVENING...WITH VALUES NOWHERE
NEAR ADVISORY CRITERIA AT LEAST FOR THE NEXT SEVERAL DAYS.

LONGWAVE TROUGH STILL PIVOTING ACROSS THE REGION TODAY WITH
SEVERAL SHORT WAVE TROUGHS CURRENTLY OBSERVED ON LATEST SATELLITE
IMAGERY. ATTENDANT SURFACE LOW JUST TO THE NORTH OVER WISCONSIN
WITH ASSOCIATED COLD FRONT EXTENDING SOUTHWEST FROM THIS LOW INTO
EASTERN IOWA. OUT AHEAD OF THIS FEATURE...LOW LEVEL FLOW HAS
CONTINUED TO FEED HIGH DEWPOINT AIR NORTH INTO NORTHERN ILLINOIS
IN THE WAKE THIS MORNINGS CONVECTION. A SIMILAR SITUATION FROM
YESTERDAY UNFOLDING TODAY WITH ATMOSPHERE TRYING TO
RECOVER/DESTABILIZE. WITH PARTIAL CLEARING OCCURRING OVER THE LAST
SEVERAL HOURS...THIS HAS BEEN OCCURRING WITH A STRONGLY UNSTABLE
ATMOSPHERE ONCE AGAIN CURRENTLY IN PLACE. LATEST RUC ANALYSIS IS
INDICATING A PRESENT INSTABILITY AXIS EXTENDING INTO NORTH CENTRAL
ILLINOIS WITH LATEST VISIBLE IMAGERY SHOWING CU FIELD ALONG FRONT
TO THE WEST BECOMING MORE AGITATED. LIMITING FACTORS ARE WITH
PRESENT CIN OVER THE AREA...WITH A FAIR AMOUNT OF CLOUD COVER
STILL PRESENT FROM SEVERAL ONGOING THUNDERSTORM COMPLEXES TO THE
SOUTH/SOUTHWEST. WITH DECENT MID LEVEL FLOW AND SEVERAL SHORT WAVE
TROUGHS FLOWING THROUGH LONGWAVE TROUGH...CONCERNS FOR
REDEVELOPMENT OVER THE AREA REMAIN AS SURFACE CONVERGENCE WILL
ALSO BE PRESENT WITH SURFACE FRONT SHIFTING EAST THIS EVENING.
CURRENT THINKING IS STILL WHAT WE HAVE BEEN THINKING ALL
DAY...THAT CONVECTION WILL DEVELOP ALONG AND AHEAD OF FRONT AND
MOVE EAST THROUGH THE CWA WITH THE BEST CHANCES FOR SEVERE WEATHER
SOUTH OF THE CITY OF CHICAGO...MAINLY ALONG AND SOUTH OF
INTERSTATE 80. THIS LOCATION DID NOT RECEIVE THE AMOUNT OF SHOWERS
AND THUNDERSTORMS THAT AREAS FURTHER NORTH DID...AND THIS LOCATION
HAS HAD MORE TIME TO DESTABILIZE. ALTHOUGH IT IS STILL POSSIBLE
FOR AREAS IN THE NORTHERN HALF OF THE CWA TO OBSERVE SOME SHOWERS
AND THUNDERSTORMS...CURRENTLY AM NOT THINKING THEY WILL BE SEVERE.
EVEN THOUGH THEY ARE NOT ANTICIPATED TO BE SEVERE...THEY WILL BE
ABLE TO PRODUCE ADDITIONAL RAINFALL TO AREAS WHICH HAVE ALREADY
SEEN ENOUGH. ALTHOUGH NOT ANTICIPATED TO BE ANYWHERE NEAR LIKE
THIS MORNINGS RAINFALL...ANY RAIN WILL ONLY ADD TO ONGOING
PROBLEMS IN CURRENT AREAL WARNING.

ONCE FRONT PUSHES THROUGH WITH UPPER LEVEL TROUGH AXIS SHIFTING TO
THE EAST...HIGH PRESSURE WILL BUILD IN BEHIND BRINGING COOLER AND
DRIER AIR. THIS WILL HELP CLEAR SKIES...MAKING FOR A PLEASANT END
TO THE WEEKEND WITH SUNNY SKIES AND FORECAST HIGHS IN THE LOWER
80S.

00 UTC THIS EVENING.

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

SATELLITE IMAGERY SHOWS INCREASED CLOUD COVER ACROSS EASTERN THIRD
OF IOWA PUSHING SOUTHEAST WITH FRONTAL BNDRY. WEAK OUTFLOW BNDRY
FROM EARLIER CONVECTION HAS PUSHED SE OF NORTH CENTRAL IL
AIRFIELDS. ATMOS HAS BEGUN TO DESTABILIZE...HOWEVER IT REMAINS
DIFFICULT TO FORECAST THE PRECISE TIMING/COVERAGE OF WHERE ADDTL
SHRA/TSRA WILL DEVELOP. LLVL FLOW REMAINS SOUTHERLY TURNING
SOUTHWESTERLY ACROSS CENTRAL ILLINOIS...WITH MAINLY A WESTERLY
FLOW ACROSS NORTHERN IL AIRFIELDS. FRONTAL BNDRY WILL CONTINUE TO
PUSH SE AND STRETCH INTO NW IL BY 22-00Z...THEN CONTINUE TO PUSH
SE. FEEL MORE CONFIDENT GOING WITH A CB MENTION AT AIRFIELDS THIS
AFTN AHEAD OF THE COLD FRONT...THEN JUST VCSH.

HIGH PRES WILL SLIDE SE OVERNIGHT AND CONTINUE TO PUSH WINDS TO
NORTHERLY BY EARLY SUN. THIS SHUD LIMIT THE POTENTIAL FOR FG
DEVELOPMENT. HOWEVER STILL FEEL FOR A FEW HRS SOME LOCATIONS COULD

219 PM CDT

A FRONTAL BOUNDARY CONTINUES TO SLOWLY DRIFT SOUTHEAST ACROSS THE
UPPER MIDWEST AND IS EXPECTED TO SLIDE ACROSS LAKE MICHIGAN EARLY
SUNDAY. AHEAD OF THIS FRONTAL BOUNDARY ARE SEVERAL WEAK AREAS OF
LOW PRESSURE THAT WILL BRING SHOWERS AND THUNDERSTORMS TO THE
SOUTHERN THIRD OF LAKE MICHIGAN THROUGH THIS EVENING. WINDS ACROSS
NORTHERN LAKE MICHIGAN HAVE TURNED NORTHERLY. FOR THE SOUTHERN
THIRD OF LAKE MICHIGAN WINDS WILL REMAIN SOUTHWESTERLY THROUGH
THIS EVENING...THEN BEGIN TO TURN NORTHWESTERLY OVERNIGHT OR
BEHIND FRONTAL PASSAGE. WINDS WILL REMAIN BREEZY THROUGH SUNDAY
DUE TO A TIGHT PRESSURE GRADIENT...RESULTING IN GUSTS BETWEEN 20
AND 24 KNOTS. HIGH PRESSURE WILL GRADUALLY BUILD INTO THE UPPER
MIDWEST LATE TONIGHT AND DRIFT ACROSS THE GREAT LAKES SUNDAY. THIS
WILL PROVIDE NORTHERLY WINDS OVER THE WATER...AND GRADUALLY
DIMINISHING SUNDAY EVENING.
