AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
302 PM CDT MON JUN 14 2010
.DISCUSSION...
1202 PM CDT
MINOR UPDATES TO GOING FORECAST. MOST OF THE SHOWER ACTIVITY FROM
EARLIER THIS MORNING HAS LIFTED NORTH INTO THE NORTHERN SECTIONS
OF ILLINOIS/SOUTHERN WISCONSIN AND SOUTHERN PORTION OF LAKE
MICHIGAN. LLVL OBS HAVE REMAINED OUT OF THE EAST...WITH A DEW PT
BNDRY TRYING TO LIFT NORTH ACROSS CENTRAL ILLINOIS. NORTH OF THIS
BNDRY DEW PTS ARE IN THE UPR 60S...SOUTH THEY ARE IN THE LOW 70S.
VISIBLE IMAGERY TRENDS HAVE SUGGESTED SOME THINNING OF THE CLOUD
SHIELD ACROSS CENTRAL ILLINOIS WITH MARGINAL DESTABILIZATION OF
THE ATMOS. THE THINKING IS THAT ANY CONVECTION THAT WOULD OCCUR
WOULD BE FOCUSED FURTHER SOUTH ACROSS CENTRAL ILLINOIS. THE
CURRENT DAY ONE CONVECTIVE OUTLOOK HAS HIGHLIGHTED THE SOUTHEAST
COUNTIES OF OUR CWFA FOR SLIGHT RISK OF SEVERE WEATHER THIS AFTN.
BEACHLER
//PREV DISCUSSION...
331 AM CDT
HAVE MADE A FEW REFINEMENTS...MAINLY TO NEAR TERM OF
FCST...FAVORING NAM GUIDANCE WHICH SEEMS TO HAVE A BETTER HANDLE
ON AREAS OF CONVECTION OUT THE GATE THIS MORNING. RADAR/SATELLITE
IMAGERY SUGGESTS ZONE OF ACTIVE CONVECTION WILL AGAIN BE MAINLY
SOUTH OF FA...SO HAVE REMOVED THUNDER MENTION OVER ALL BUT FAR WRN
AND SRN PORTIONS OF FA WHERE FORECAST SOUNDINGS SHOW AT LEAST SOME
INSTABILITY AND LOW CLOUD COVER IS APT TO BE LESS INHIBITIVE OF
DEVELOPMENT. AREAS OF DENSE FOG OVER MAINLY RURAL AREAS OF NRN IL
SHOULD LIFT INTO STRATUS DECK SOON AFTER SUNRISE...BUT THIS WILL
STILL BE A FACTOR LIMITING THUNDER CHANCES. CLUSTER NOW LIFTING
NEWD ACROSS SERN IA AND NERN MO SHOULD REMAIN ACTIVE THROUGH THE
EARLY MORNING HOURS...WITH SOME ANVIL CANOPY RAIN/THUNDER POSSIBLE
INTO FAR WRN FA BEFORE COMPLEX ENTERS DIURNAL DOWN TIME AND TURNS
EASTWARD AS IT CROSSES MS RIVER. AREAS WELL SOUTH OF I-80 WILL BE
CLOSER TO THUNDERSTORM INITIATION AREA...AND MAY DEVELOP MORE CAPE
AS DAY GOES ON SO WILL JUST GO WITH LIKELY THUNDER OVER SRN CWA.
AS ELONGATED UPPER LOW FROM ERN WY-NRN MN EVOLVES INTO A MORE
PRONOUNCES CLOSED LOW OVER THE DAKOTAS TODAY AND
TONIGHT...AMPLIFICATION OF SHORT WAVE EXTENDING SOUTH ACROSS
CENTRAL PLAINS STATES IS EXPECTED TO EJECT SMALLER SCALE WAVE NEWD
OUT OF THE TX PANHANDLE REGION TONIGHT AS WELL. COMBINATION OF
THESE FEATURES SHOULD INCREASE CHANCES FOR THUNDER ON TUESDAY AND
WILL CONCUR WITH POPS FROM MOS GUIDANCE...GOING WITH LIKELY POPS
THOUGH FEEL THAT BEST CHANCES FOR THUNDER WILL BE N OF REGION
ASSOCIATED WITH BETTER DYNAMICS AND MID LEVEL LAPSE RATES TO
NW...AND OVER MID MS AND OH VALLEY REGION WHERE THERMODYNAMICS
WILL REMAIN MUCH MORE IMPRESSIVE.
AS MAIN SHORT WAVE EJECTS ENEWD ACROSS UPPER GREAT LAKES TUESDAY
NIGHT...MORE PRONOUNCED AND SUSTAINED AREA OF SUBSIDENCE AND
DRYING TO OVERSPREAD MIDWEST BY 12Z WED...ENDING PERIOD OF
CLOUDINESS AND PERIODIC RAIN...AND INTRODUCING A COUPLE OF DAYS OF
DRY...SEASONABLE WEATHER.
MADE LITTLE OR NO CHANGE TO DAY 5 AND BEYOND AS GUIDANCE REMAINS
SOMEWHAT CONSISTENT IN MAINTAINING PROGRESSIVE WAVE PATTERN ACROSS
ROCKIES...NRN TIER OF CONUS AND SRN CANADA. THIS WILL RESULT IN
RETURN OF MORE TROPICAL AIR AGAIN BY FRIDAY...ALONG WITH A RENEWED
CHANCE OF SHOWERS/THUNDERSTORMS.

.AVIATION...
//ORD AND MDW CONCERNS...UPDATED 20Z...
BIGGEST CONCERN OVER THE NEXT FEW HOURS REMAINS THE CIGS AT
ORD. FOR 20Z UPDATE...HAVE KEPT ORD IFR THROUGH TUESDAY MORNING
DUE TO PERSISTENCE AND UNCERTAINTY. OTHER CONCERNS REVOLVE AROUND
HOW LOW CIGS/VSBYS WILL GO TONIGHT/EARLY TUESDAY AT BOTH TERMINALS
DUE TO ABUNDANT LOW LEVEL MOISTURE TRAPPED BELOW A FRONTAL
INVERSION. FINAL MAJOR CONCERN IS PRECIPITATION COVERAGE THROUGH
THIS EVENING. CURRENT THINKING IS THAT SCATTERED COVERAGE IS
LIKELY...WITH THE THUNDER PRIMARILY SOUTH OF THE TERMINAL AREA.
BAK
//DISCUSSION...UPDATED 18Z...
A FRONTAL BOUNDARY REMAINS SOUTH OF THE TERMINALS EARLY THIS
AFTERNOON. A WAVE...CURRENTLY OVER IOWA...WILL SLOWLY TRACK EAST
ALONG THE BOUNDARY...EVENTUALLY PUSHING EAST OF THE TERMINALS BY
TUESDAY MORNING. EXPECT SHOWERS TO REDEVELOP THIS AFTERNOON INTO
THIS EVENING THROUGH A COMBINATION OF DIURNAL HEATING AND WEAK
FORCING FROM THE APPROACH OF THE WAVE. THE STRONGEST INSTABILITY
SHOULD REMAIN SOUTH OF THE TERMINALS...SO THUNDER DOES NOT APPEAR
TO BE A THREAT AT THIS TIME. ONCE THE PRECIPITATION ENDS AND LOWER
ATMOSPHERE BEGINS TO COOL THIS EVENING...EXPECT CIGS/VSBYS TO
FALL TO IFR/LIFR FOR THE DURATION OF THE NIGHT INTO TUESDAY
MORNING. WINDS SHOULD GENERALLY BE 10 KTS OR LESS OVERALL...
STAYING PREDOMINANTLY NORTHEAST IN ADVANCE OF THE WAVE THIS
AFTERNOON/EVENING...VARIABLE AS THE WAVE PASSES BY...AND WESTERLY
IN ITS WAKE TUESDAY MORNING.

HOURS...AS WELL AS AT BOTH TERMINALS FOR THE OVERNIGHT/EARLY

213 PM CDT
A STATIONARY FRONT CONTINUES TO SPAN ACROSS NORTHERN ILLINOIS WITH A
SERIES OF LOW PRESSURE SYSTEMS EXPECTED TO PROGRESS ALONG THE
BOUNDARY THROUGH TUESDAY. AREAS OF DENSE FOG HAVE PERSISTED THROUGH
THE DAY TODAY AND ARE EXPECTED TO CONTINUE THROUGH THE EVENING.
EASTERLY WINDS OF 15 TO 20 KTS WITH GUSTS TO 25 KTS ARE EXPECTED
TONIGHT THROUGH LATE TUESDAY AFTER WHICH A LOW PRESSURE SYSTEM IS
EXPECTED TO MOVE ACROSS NORTHERN ILLINOIS NORTHEAST ACROSS THE
WESTERN PORTIONS OF LAKE MICHIGAN. THE PRESSURE GRADIENT IS EXPECTED
TO TIGHTEN AHEAD OF THE SYSTEM...ESPECIALLY ACROSS THE NORTHERN HALF
OF LAKE MICHIGAN DURING THE AFTERNOON INTO THE EVENING HOURS TUESDAY
CAUSING GUSTY NEAR GALE WIND CONDITIONS FOR THE NORTHERN HALF OF THE
LAKE. THE GRADIENT WILL BEGIN TO WEAKEN LATE TUESDAY EVENING AS THE LOW
FILLS. BY WEDNESDAY HIGH PRESSURE IS EXPECTED TO BUILD INTO THE
REGION CENTERED OVER IOWA AND DRIFTING TO THE NORTHEAST. WINDS WILL
DECREASE AND SHIFT TO THE SOUTHWEST MIDWEEK.

RATZERThe Indianapolis radar (KIND), 130 km away, was scanning. The volume nearest the first event began at 20:03 UTC.
1 hail, 1 thunderstorm wind. Local standard time, as filed.
Hail as large as softballs produced catastrophic damage to crops from near Boswell east and southeast to the Warren County line south of Templeton. An estimated 5,000 acres of corn crop was destroyed. The hail also caused significant roof damage to many houses.
Severe winds of 60 mph to 75 mph developed just north of Boswell and continued east and southeast to the Warren County line south of Oxford. There were two areas of more intense wind damage found along Highway 352 between Boswell and Oxford. The first area of intense damage was near Chase where a large hardwood tree was snapped at the base with other trees and large tree limbs blown down in a few mile wide area around Chase. The most intense damage in this area was consistent with winds of 90 to 100 mph. The second area of intense damage was located farther east on Highway 352 just west of Oxford. A well built barn was partially destroyed in this location with debris from the barn spread several hundred yards down stream. Several trees were blown down in the area with some minor roof damage to a nearby home. The most intense damage was consistent with winds of 90 to 100 mph.
