Special Weather Statement 15:04:32.5372928

...POWERFUL COLD FRONT TO BLAST THROUGH THE AREA LATE THIS
AFTERNOON INTO THIS EVENING...

A POTENT COLD FRONT WILL SWEEP RAPIDLY ACROSS NORTHERN AND CENTRAL
ILLINOIS AND NORTHWEST INDIANA LATE THIS AFTERNOON INTO EARLY THIS
EVENING. AS THE FRONT MOVES THROUGH TEMPERATURES WILL RAPIDLY FALL
BY AS MUCH AS 20 DEGREES IN LESS THAN A HOUR AS WINDS SHIFT TO THE
NORTHWEST.

THE FRONT AND THE LEADING EDGE OF THE MUCH COLDER AIR WILL REACH A
HARVARD...TO DE KALB...TO OTTAWA LINE BY AROUND 4 PM. BY AROUND 5
PM...THE FRONT SHOULD EXTEND FROM THE NORTHERN SUBURBS OF CHICAGO
SOUTH THROUGH THE NEAR WESTERN SUBURBS TO NEAR PLAINFIELD...AND
SOUTHWEST TO PONTIAC. BY AROUND 6 PM...THE FRONT WILL BE WELL OUT
OVER SOUTHERN LAKE MICHIGAN...SOUTH TO NEAR HAMMOND INDIANA...TO
NEAR PAXTON. THE FRONT IS EXPECTED TO MOVE OUT OF EXTREME
NORTHWEST INDIANA BY 7 OR 730 PM CDT.

IN ADDITION TO A RAPID DROP IN TEMPERATURES...A NARROW LINE OF
SHOWERS AND POSSIBLE THUNDERSTORMS WILL ACCOMPANY THE FRONT AND
COULD PRODUCE BRIEF WIND GUSTS OVER 40 MPH. ADDITIONAL SHOWERS AND
SOME THUNDERSTORMS WILL LIKELY AFFECT THE REGION AT TIMES THROUGH
THIS EVENING.

Flood Potential Outlook 10:20:14.3684186

IN TABLE 1 BELOW...THE CURRENT (CS) AND HISTORICAL (HS) OR NORMAL
PROBABILITIES OF EXCEEDING MINOR...MODERATE...AND MAJOR FLOOD STAGES
ARE LISTED FOR THE VALID TIME PERIOD.

CS VALUES INDICATE THE PROBABILITY OF REACHING A FLOOD CATEGORY
BASED ON CURRENT CONDITIONS.

HS VALUES INDICATE THE PROBABILITY OF REACHING A FLOOD CATEGORY
BASED ON HISTORICAL OR NORMAL CONDITIONS.

WHEN THE VALUE OF CS IS MORE THAN HS...THE PROBABILITY OF
EXCEEDING THAT LEVEL IS HIGHER THAN NORMAL. WHEN THE VALUE OF CS IS
LESS THAN HS...THE PROBABILITY OF EXCEEDING THAT LEVEL IS LOWER
THAN NORMAL.

OUTLOOKS OF TEMPERATURE AND PRECIPITATION. BY PROVIDING A RANGE OF

ALTHOUGH A WW IS NOT CURRENTLY ANTICIPATED...THE AREA WILL CONTINUE
TO BE MONITORED FOR A POSSIBLE INCREASE IN SEVERITY THIS AFTERNOON.

IN RESPONSE TO FORCING FOR ASCENT IN ASSOCIATION WITH AN UPPER WAVE
NOTED ON WV IMAGERY OVER ERN IA/WRN IL...AND AN MCV NOTED OVER NWRN
IL. MOIST LOW-LEVEL WSWLY WINDS NEAR 35-40 KT PER AREA VAD WIND
PROFILE DATA ARE LIKELY MAINTAINING WEAK ELEVATED
INSTABILITY...PARTICULARLY WITH THE SRN MOST EXTENT OF THE LINE OVER
SRN/CNTRL IL. HOWEVER...THE MOIST INFLOW MAY GRADUALLY DECREASE AS
THE PRIMARY FORCING FOR ASCENT PROGRESSES AWAY FROM THE REGION. WEAK
MID-LEVEL WINDS AND OTHERWISE MARGINAL MOISTURE PROFILES MAY HINDER
THE DEVELOPMENT OF AN ORGANIZED SEVERE THREAT...THOUGH ISOLATED
INSTANCES OF MARGINALLY SEVERE HAIL ARE POSSIBLE WITH STRONGER CORES
THAT CAN DEVELOP.

...SHORT PERIOD OF STRONG WINDS THIS EVENING...

A STRONG COLD FRONT WILL CONTINUE TO MOVE ACROSS NORTHEASTERN
ILLINOIS OVER THE NEXT COUPLE OF HOURS. BEHIND THIS FRONT...THERE WILL
BE A SHORT PERIOD OF STRONG WINDS. AS THE FRONT PASSES THE WINDS
WILL QUICKLY TURN WEST NORTHWESTERLY AND INCREASE TO 20 TO 30 MPH
WITH SOME GUSTS UP TO 45 MPH. THESE WINDS MAY LAST FOR UP TO AN
HOUR BEFORE THEY ABATE.

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 171645Z - 171815Z

PROBABILITY OF WATCH ISSUANCE...5 PERCENT

SUMMARY...ELEVATED THUNDERSTORMS WILL POSE A RISK FOR ISOLATED
MARGINALLY SVR HAIL THIS AFTERNOON. A WW IS NOT LIKELY ATTM.

DISCUSSION...REGIONAL RADAR IMAGERY AT 1630Z SHOWS A BAND OF
THUNDERSTORMS LIFTING N-NEWD ACROSS NERN MO. THIS ACTIVITY IS
OCCURRING WITHIN A ZONE OF 850 MB MOISTURE ADVECTION...AND ABOVE A
CLOUDY/STABLE SURFACE AIRMASS. THIS MOISTENING COMBINED WITH
MIDLEVEL LAPSE RATES FROM 7-7.5 C/KM IS AIDING IN A NWD EXPANSION OF
MUCAPE VALUES NEAR 500-1000 J/KG. IN ADDITION...STRONG DEEP-LAYER
SWLY FLOW AHEAD OF AN UPPER TROUGH OVER THE CNTRL PLAINS IS
RESULTING IN 0-6 KM BULK SHEAR AROUND 40 KT. THIS ENVIRONMENT WILL
FAVOR ADDITIONAL CLUSTERS OF THUNDERSTORMS OVER NERN MO AND CNTRL IL
DURING THE AFTERNOON. A FEW MAY BECOME STRONG/SVR...AND POSE A RISK
FOR ISOLATED MARGINALLY SVR HAIL.
