Mesoscale Discussion 21:01:18.7492122

AREAS AFFECTED...PORTIONS ERN IA...NRN IL...SRN WI.

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 300200Z - 300400Z

PROBABILITY OF WATCH ISSUANCE...40 PERCENT

SUMMARY...ISOLATED/QUICKLY DEVELOPING SVR TSTM PRODUCED 2.5-INCH
HAIL REPORT NEAR DBQ AT 130Z. PER COORD W/AFFECTED WFOS...NO WW IS
BEING ISSUED YET. HOWEVER...CONVECTIVE TRENDS WILL BE MONITORED FOR
UPSCALE GROWTH THAT COULD COMPEL WW ISSUANCE...IN ENVIRONMENT THAT
SHOULD REMAIN FAVORABLE FOR OCNL LARGE HAIL FROM ANY SUSTAINED
CONVECTION.

DISCUSSION...ACTIVITY NEAR DBQ DEVELOPED NEAR DIFFUSE SFC WARM FRONT
EXTENDING WNWWD ACROSS SRN MN INTO ERN SD...AND ALSO..NEAR NERN END
OF FRONTOLYTIC WARM-FRONTAL CORRIDOR THAT EXTENDS INTO LOW OVER
CENTRAL/SWRN KS. NEARBY DVN RAOB...IN WARM SECTOR...SAMPLED STEEP
MIDLEVEL LAPSE RATES AND INCREASING LOW-LEVEL MOISTURE...WITH
ROUGHLY 1-INCH PW SUPPORTING MLCAPE 800-900 J/KG. MUCAPE FOR
INCREASINGLY MOIST PARCELS ROOTED AROUND 800-850 MB IS IN 2000-2500
J/KG RANGE...MORE REPRESENTATIVE OF RAPID INITIAL INTENSIFICATION
RATE OF CONVECTION OBSERVED SO FAR. WITH NEAR-SFC
COOLING...ACTIVITY SHOULD BE MOSTLY ELEVATED...BUT WITH POTENTIAL TO
SEND ISOLATED STG/DAMAGING GUST THROUGH SHALLOW NEAR-SFC STABLE
LAYER. MAIN CONCERN WILL BE HAIL.

SIGNALS FOR KINEMATIC SUPPORT ARE MIXED...WITH RELATIVELY WEAK
MID-UPPER WINDS LIMITING CLOUD-LAYER SHEAR. HOWEVER...LOW-LEVEL WAA
AND RELATED VEERING OF WINDS WITH HEIGHT CONTRIBUTE TO FAVORABLE
EFFECTIVE SRH AROUND 200-250 J/KG. THOUGH FIXED-LAYER SRH SHOULD
INCREASE BENEATH STRENGTHENING SWLY LLJ...NEAR-SFC DIABATIC
STABILIZATION WILL EFFECTIVELY TRUNCATE SOME OF THAT HELICITY IN
VERTICAL. EFFECTIVE SHEAR MAGNITUDE 35-40 KT IS EXPECTED TO
CONTINUE.

CONCERNING...TORNADO WATCH 118...

VALID 180121Z - 180245Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 118 CONTINUES.

SUMMARY...THE SVR THREAT CONTINUES ACROSS REMAINING VALID PORTIONS
OF WW118.

DISCUSSION...IN NRN INDIANA...ONE CLUSTER OF WAA-RELATED CONVECTION
CONTINUES TO ADVANCE NWD/EWD AWAY FROM ANY RESIDUAL BOUNDARY-LAYER
BUOYANCY RESIDING S OF A QUASI-STATIONARY FRONT STRETCHING FROM
W-CNTRL OHIO WWD INTO CNTRL IL AND CNTRL MO. ASIDE FROM A RISK FOR
MARGINALLY SVR HAIL...THIS ACTIVITY SHOULD WEAKEN AS IT BECOMES
INCREASINGLY ELEVATED...AND BUOYANCY ATOP THE SFC COLD DOME WEAKENS
WITH NOCTURNAL COOLING.

ADDITIONAL CLUSTERS OF CONVECTION UPSTREAM ACROSS NERN MO...W-CNTRL
IL...AND SERN IA WILL CONTINUE SPREADING ENEWD...POTENTIALLY
ORGANIZING INTO ONE OR MORE ORGANIZED LINES OF STORMS. THIS ACTIVITY
WILL LIKELY REMAIN ELEVATED TO THE N OF THE SFC FRONT...WHERE STRONG
STATIC STABILITY IS NOTED IN THE LOWEST 1 KM AGL PER THE ILX 00Z
RAOB. NEVERTHELESS...STRONG 0-6-KM SHEAR WILL MAINTAIN ORGANIZED
CONVECTION...WITH SVR HAIL BEING THE PRIMARY CONCERN. HOWEVER...SVR
WINDS CANNOT BE RULED OUT IF DOWNDRAFTS CAN PENETRATE THROUGH THE
STABLE LAYER TO THE SFC...ESPECIALLY WITH ELEVATED BOWING LINE
SEGMENTS/SUPERCELLS. VERY SMALL TEMPERATURE-DEWPOINT SPREADS IN THE
LOW LEVELS...AND ONLY MODEST MID-LEVEL LAPSE RATES...WILL GREATLY
MITIGATE SUCH POTENTIAL.

CONCERNING...TORNADO WATCH 118...

VALID 172346Z - 180115Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 118 CONTINUES.

SUMMARY...THE THREAT FOR SVR TSTMS AND PERHAPS A TORNADO CONTINUES
ACROSS MAINLY EAST-CENTRAL IL/WEST-CENTRAL IN PORTION OF WW.
ELSEWHERE...CONVECTIVE OUTFLOW WILL INCREASINGLY STABILIZE BOUNDARY
LAYER RESULTING IN MAINLY A LARGE HAIL THREAT THROUGH 05Z.

DISCUSSION...A COMPLEX SURFACE PATTERN EXISTS ACROSS WW AREA AS
CONVECTIVE OUTFLOWS HAVE MASKED THE WARM FRONT RESULTING IN A
REDUCED TORNADO THREAT OVER MUCH OF THE WW AREA. AT 23Z SURFACE
OBSERVATIONS AND RADAR TRENDS SHOW A NWWD-MOVING OUTFLOW BOUNDARY
FROM JUST SOUTH OF GUS TO HUF. FARTHER WEST...CONVECTIVE OUTFLOW HAD
SPREAD EAST TO ROUGHLY FROM NEAR TAZ TO 25 S OF SBN. TSTMS WITHIN A
SMALL CORRIDOR BETWEEN THESE TWO OUTFLOWS MAY BRIEFLY POSE A RISK
FOR LOW-LEVEL ROTATION BEFORE BEING UNDERCUT BY OUTFLOW BY 0030Z.
AFTERWARD...EFFECTIVE SHEAR VALUES AVERAGING 45-55KT AND MUCAPES
FROM 500 J/KG OVER NRN PORTIONS OF WW AND TO AROUND 2000 J/KG OVER
SRN PORTIONS WOULD FAVOR MAINLY LARGE HAIL. AN ISOLATED DAMAGING
WIND GUST CANNOT BE RULED OUT WHERE STRONG WINDS CAN PENETRATE THE
SHALLOW CONVECTIVE OUTFLOW OVER SRN PORTIONS OF WW AREA.

CONCERNING...SEVERE THUNDERSTORM WATCH 113...

VALID 171833Z - 171930Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 113
CONTINUES.

SUMMARY...THE SEVERE THREAT WILL LIKELY CONTINUE ACROSS WW113 OVER
THE NEXT FEW HOURS. THE MAIN SEVERE THREAT WILL BE HAIL...BUT A FEW
STRONG WIND GUSTS COULD ALSO OCCUR.

DISCUSSION...THUNDERSTORMS CONTINUE TO DEVELOP/PERSIST IN AN AREA OF
WAA ALONG AND NORTH OF A QUASI-STATIONARY BOUNDARY DRAPED ACROSS N
ILLINOIS...EXTENDING WWD INTO S IOWA. ALONG AND AHEAD OF THESE
THUNDERSTORMS THE ENVIRONMENT IS CHARACTERIZED BY MUCAPE VALUES
BETWEEN 500-1000 J/KG AND DEEP LAYER SHEAR AOA 50KTS. THIS WOULD
SUGGEST CONTINUED UPDRAFT ORGANIZATION..AND AN ATTENDANT SEVERE
WEATHER THREAT THROUGH THE AFTERNOON. HAIL APPEARS TO BE THE PRIMARY
THREAT...BUT ISOLATED DAMAGING WIND GUSTS CANNOT BE RULED OUT.

FARTHER WEST ACROSS WW113...ACROSS S IOWA...WAA WILL PERSIST
THROUGHOUT THE AFTERNOON. HERE...MUCAPE VALUES REMAIN AOA 500 J/KG
AND DEEP LAYER SHEAR SUFFICIENT FOR THUNDERSTORM ORGANIZATION.
ALTHOUGH THE INTENSITY OF THUNDERSTORMS APPEARS TO BE WANING...AN
ISOLATED SEVERE THREAT CANNOT BE RULED OUT.

A HALF IN A AN HOUR. RAINFALL TOTALS FOR TODAY ACROSS THE WARNING
AREA BY THIS EVENING COULD EXCEED 3 INCHES IN SOME AREAS.

* RUNOFF FROM THIS EXCESSIVE RAINFALL WILL CAUSE FLASH FLOODING TO

SUMMARY...A FEW STRONGER THUNDERSTORMS ARE EXPECTED THIS AFTERNOON.
WHILE A MARGINALLY SEVERE WIND GUST AND SOME SMALL HAIL IS
POSSIBLE...OVERALL SEVERE THREAT IS EXPECTED TO REMAIN LOW AND A WW
IS NOT ANTICIPATED AT THIS TIME.

DISCUSSION...CONVECTION CURRENTLY ONGOING UPSTREAM ACROSS NRN IL
WILL CONTINUE TO SHIFT E/NE ACROSS SRN LAKE MICHIGAN INTO SW
MICHIGAN THIS AFTERNOON. WHILE THESE STORMS ARE LIKELY TO REMAIN
ELEVATED GIVEN COOL BOUNDARY LAYER WELL TO THE NORTH OF A WARM FRONT
ACROSS THE OHIO VALLEY...STRONG EFFECTIVE SHEAR WILL OVERSPREAD THE
AREA. IN CONJUNCTION WITH MODEST MIDLEVEL LAPSE RATES AND SOME WEAK
INSTABILITY...AN ISOLATED STRONG/SEVERE WIND GUST MAY BE POSSIBLE IN
STRONGER CELLS. COLD TEMPERATURES ALOFT /-10 TO -15 C AT 500 MB/ MAY
ALSO SUPPORT SMALL HAIL PRODUCTION. OVERALL SEVERE THREAT SHOULD
REMAIN SUFFICIENTLY LOW THAT A WW DOWNSTREAM OF SEVERE WATCH 113 IS
NOT ANTICIPATED AT THIS TIME.
