Hail in Illinois, June 25, 2014

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
337 PM CDT WED JUN 25 2014

.DISCUSSION...
336 PM CDT

MAIN FORECAST CONCERNS/CHALLENGES ARE WITH CONTINUED THUNDERSTORM
CHANCES THROUGH THE PERIOD...AS WELL AS WARMING TREND INTO THE
WEEKEND.

OF PARTICULAR CONCERN IN THE NEAR TERM ARE WITH THE SCATTERED
THUNDERSTORMS CONTINUING TO DEVELOP ACROSS NORTH CENTRAL AND
NORTHEAST ILLINOIS. LATEST RADAR IMAGERY DEPICTING SEVERAL STRONG
THUNDERSTORMS CONTINUING TO DEVELOP AT THIS TIME...WITH SMALL HAIL
AND WINDS TO 50 MPH THE THREATS AT THIS TIME. AS WAS ALSO
ANTICIPATED...HEAVY RAIN WITH LOCALIZED MINOR FLOODING CONTINUES
TO BE A THREAT WITH ONE OF THE STRONGER STORMS PRODUCING SLIGHTLY
OVER AN INCH AS IT MOVED OVER THE OFFICE HERE IN ROMEOVILLE.
THUNDERSTORM DEVELOPMENT WILL CONTINUE TO BE FOCUSED ALONG BEST
SURFACE CONVERGENCE NEAR FRONT FROM ROCKFORD SOUTHEAST TO KANKAKEE
OVER THE NEXT SEVERAL HOURS...WHERE INSTABILITY AXIS RESIDES. AS
LARGE VORT MAX WELL TO THE NORTH CONTINUES EAST THIS
AFTERNOON...TAIL END OF SHORTWAVE TROUGH WILL ALSO EXIT. BEST
LARGE SCALE LIFT WILL BE LOST WITH THE COVERAGE OF STORMS LIKELY
DECREASING THROUGH EARLY EVENING. DO CONTINUE TO MONITOR SEVERAL
OUTFLOW BOUNDARIES WHICH HAVE DEVELOPED FROM THIS AFTERNOONS
CONVECTION...WHICH COULD BE A FOCUS FOR ENHANCED DEVELOPMENT THIS
AFTERNOON AS WELL AS A SOURCE OF LOW HORIZONTAL LEVEL SHEAR. THIS
LOW LEVEL SHEAR IN THE PRESENCE OF THE STEEP LAPSE RATES COULD
PROVIDE A SCENARIO SIMILAR TO YESTERDAY...WITH ISOLATED FUNNEL
CLOUDS POSSIBLY DEVELOPING. THIS AFTERNOON BEFORE THE STORMS
DIMINISH THROUGH EARLY EVENING...SMALL HAIL...GUSTY WINDS...AND
HEAVY RAIN WILL STILL BE THE MAIN THREATS WITH AN ISOLATED SEVERE
THREAT STILL NOT OUT OF THE QUESTION.

FOG ALONG THE SHORE WILL ONCE AGAIN BE AN ISSUE THIS EVENING
THROUGH THURSDAY MORNING. EXPECT THIS FOG AND LOW STRATUS TO SPILL
BACK INLAND LATE THIS EVENING MAINLY AFFECTING AREAS NEAR LAKE
MICHIGAN DURING THIS TIME...BUT WITH THIS FOG/STRATUS LIKELY
MOVING FURTHER INLAND AND AFFECTING A GOOD PORTION OF THE CWA
OVERNIGHT INTO EARLY THURSDAY MORNING. WILL MAKE MENTION OF FOG IN
THE GRIDS/ZONES AND HWO...AN MONITOR THIS INLAND PUSH THIS EVENING
FOR POSSIBLE DENSE FOG ADVISORY AGAIN TONIGHT.

AFTER THIS AFTERNOON/EARLY EVENINGS DEVELOPMENT DIMINISHES...DONT
EXPECT ANY SHOWER/THUNDERSTORM DEVELOPMENT FOR THE REMAINDER OF
THE NIGHT. DO EXPECT THURSDAY MORNING TO REMAIN MOSTLY DRY AS WELL
AS ANY THUNDERSTORM DEVELOPMENT SHOULD STAY WELL WEST OF THE CWA
DURING THIS TIME. UPPER LEVEL RIDGING SHOULD BEGIN ACROSS THE
REGION DURING THE DAY THURSDAY...BUT WITH SOME POTENTIAL FOR SOME
WEAK MID LEVEL ENERGY TO DRIFT EASTWARD TOWARDS THE CWA. THIS
POTENTIAL ENERGY COINCIDING WITH A LINGERING BOUNDARY STRETCHED
ACROSS THE REGION COULD PROVIDE FOR SOME DEVELOPMENT ONCE AGAIN
THURSDAY AFTERNOON. BEST FOCUS SHOULD REMAIN TO THE WEST OF THE
CWA BUT WITH THE POSSIBILITY FOR ANY DEVELOPMENT TO DRIFT EASTWARD
TOWARDS THE CWA...DID MAINTAIN SOME LOW CHANCE POPS. DO EXPECT
THURSDAY NIGHT BE ON THE DRIER SIDE WHILE THE STRONGER FLOW/ENERGY
REMAINS WELL TO THE NORTHWEST...BUT WITH POTENTIAL FOR WAA PRECIP
TO SWING EAST ACROSS NORTH CENTRAL ILLINOIS...DID LEAVE A SLIGHT
CHANCE MENTION IN THE GRIDS. RISING HEIGHTS AND PERSISTENT WAA
WILL BE THE TREND INTO THE WEEKEND...WHILE ENERGY THE NORTHWEST
SLOWLY APPROACHES. A VERY MOIST AND WARM ENVIRONMENT WITH SOME
POTENTIAL FOR FOCI FOR THUNDERSTORM DEVELOPMENT TO REMAIN...HAVE
WARRANTED CHANCE POP MENTION INTO THE WEEKEND WHILE TEMPS IN THE
UPPER 80S ARE EXPECTED.

* SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON/EVENING.
* IFR CIGS/VSBY RETURNING LATE THIS EVENING/OVERNIGHT.

BMD

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

HIGH PRESSURE IS BUILDING INTO THE NORTHERN GREAT LAKES REGION WITH
NORTHEAST FLOW OFF OF LAKE MICHIGAN IN PLACE AT THE CHICAGO
TERMINALS WHILE WEST TO NORTHWEST WINDS ARE IN PLACE FARTHER WEST
OVER NORTH CENTRAL IL. THERE IS AN AREA OF CONVERGENCE IN BETWEEN
THESE TWO FEATURES WHICH WILL LIKELY BE THE FOCUS FOR SHRA/TSRA
DEVELOPMENT EARLY THIS AFTERNOON AS AN UPPER LEVEL DISTURBANCE
SKIRTS JUST TO OUR NORTH OVER WISCONSIN. GROWING CUMULUS IS NOW
EVIDENT ON SATELLITE IMAGERY FROM ROUGHLY LSE THROUGH RFD TO CNI.
STORMS FORMING IN THIS AREA ARE EXPECTED TO MOVE EAST...BUT MAY LOSE
SOME STEAM AS THEY NEAR THE LAKE AND MOVE OVER THE LAKE COOLED AIR.
THIS EVENING AND TONIGHT...WITH THE LOSS OF DAYTIME HEATING AND
MIXING...EXPECT THE MARINE CIGS TO SPREAD BACK INLAND OVER THE
TERMINALS REDUCING VSBY AND CIGS BACK TO IFR.

//ORD AND MDW CONFIDENCE...UPDATED 18Z...

.MARINE...
239 PM CDT

HIGH PRESSURE CENTERED OVER ONTARIO WILL SPREAD SOUTHWARD INTO THE
GREAT LAKES INTO TONIGHT WHILE LOW PRESSURE STRETCHING FROM NOVA
SCOTIA SOUTHWEST INTO THE MID ATLANTIC CONSOLIDATES OVER SOUTHERN
NEW ENGLAND FRIDAY. DRIER AIR IS STARTING TO FILTER SOUTHWARD ACROSS
NORTHERN PORTIONS OF THE LAKE WHICH SHOULD HELP REDUCE THE COVERAGE
OF FOG ACROSS NORTHERN PORTIONS OF THE LAKE INTO THE EVENING. DENSE
FOG WILL LIKELY REMAIN ACROSS THE SOUTHERN HALF TO TWO-THIRDS OF THE
LAKE THROUGH TONIGHT SO WILL MAINTAIN THE DENSE FOG ADVISORY.
OTHERWISE...WINDS WILL REMAIN ON THE LIGHT SIDE FROM THE NORTH AND
NORTHEAST TONIGHT AND LIKELY BECOME VARIABLE ONSHORE THURSDAY WITH
HIGH PRESSURE RIDGING SPREADING DOWN THE LAKE. THE HIGH WILL MOVE
EAST INTO FRIDAY WHILE LOW PRESSURE DEVELOPS ACROSS THE HIGH PLAINS.
WIND SPEEDS WILL LIKELY REMAIN LIGHT GOING INTO FRIDAY AND FAVOR A
SOUTHEAST DIRECTION BUT THE FLOW MAY BE LIGHT ENOUGH THAT THEY
BECOME ONSHORE. THE PRESSURE GRADIENT WILL GRADUALLY STRENGTHEN
SATURDAY BRINGING INCREASING SOUTHERLY WINDS BUT THE STRONG WARM
ADVECTION WILL KEEP  SHARP INVERSION IN PLACE SO SPEED INCREASE MAY
BE LIMITED. THE LOW ACROSS THE PLAINS WILL LIFT NORTHWARD INTO THE
CANADIAN PRAIRIES AND INTENSIFY SUNDAY KEEPING A TIGHT PRESSURE
GRADIENT ACROSS THE LAKE AND TURN WINDS MORE SOUTHWESTERLY FOR
SUNDAY AFTERNOON. THE STABLE LAYER WILL ONCE AGAIN LIMIT WIND SPEEDS
ACROSS THE OPEN WATERS BUT OFFSHORE FLOW ON THE WEST AND SOUTH
SHORES WILL ALLOW FOR A STRONGER BREEZE STRETCHING A FEW MILES FROM
SHORE. THE SURFACE LOW WILL THEN TRACK EASTWARD ACROSS SOUTHERN
MANITOBA AND WESTERN ONTARIO EARLY NEXT WEEK BRINGING A COOL FRONT
ACROSS THE LAKE TURNING WINDS WESTERLY.
