NWS STORM PREDICTION CENTER NORMAN OK
150 PM CDT WED JUN 12 2013
THE NWS STORM PREDICTION CENTER HAS ISSUED A
* TORNADO WATCH FOR PORTIONS OF
NORTHEAST IOWA
NORTHERN ILLINOIS
EXTREME SOUTHEAST MINNESOTA
SOUTHWEST WISCONSIN
* EFFECTIVE THIS WEDNESDAY AFTERNOON AND EVENING FROM 150 PM
UNTIL 900 PM CDT.
...THIS IS A PARTICULARLY DANGEROUS SITUATION...
* PRIMARY THREATS INCLUDE...
SEVERAL INTENSE TORNADOES LIKELY
SEVERAL SIGNIFICANT DAMAGING WIND GUSTS TO 80 MPH POSSIBLE
SEVERAL VERY LARGE HAIL EVENTS TO 3 INCHES IN DIAMETER POSSIBLE
THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 65 STATUTE
MILES EITHER SIDE OF A LINE FROM 35 MILES WEST SOUTHWEST OF MASON
CITY IOWA TO 20 MILES EAST SOUTHEAST OF ROCKFORD ILLINOIS. FOR A
COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
UPDATE (WOUS64 KWNS WOU8).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS.
&&
DISCUSSION...POTENTIALLY EXPLOSIVE THUNDERSTORM DEVELOPMENT IS
POSSIBLE OVER THE NEXT FEW HOURS AS GRADUALLY DEEPENING SURFACE LOW
TRACKS EAST ALONG A FRONTAL ZONE SITUATED FROM NORTHEAST IOWA
EASTWARD ALONG THE WI/IL BORDER TO LAKE MICHIGAN. A VOLATILE WARM
AND VERY MOIST AIRMASS SHOULD FUEL INTENSE THUNDERSTORM UPDRAFTS
ACROSS THESE AREAS WHERE MID LEVEL FLOW IN EXCESS AROUND 50KT
SUPPORTS UPDRAFT PERSISTENCE AND ORGANIZATION. A NUMBER OF
SUPERCELLS ARE EXPECTED PRIOR TO A CONSOLIDATION OF STORMS INTO A
LARGE MCS TOWARD EVENING. LOW LEVEL SHEAR/HELICITY NEAR THE SURFACE
LOW AND ALONG THE FRONT WILL SUPPORT SOME TORNADOES WITH ANY
DISCRETE CELLS. A COUPLE STRONG TORNADOES SEEM POSSIBLE WITHIN THIS
ENVIRONMENT OVER THE NEXT SEVERAL HOURS IN ADDITION TO VERY LARGE
HAIL AND LOCALIZED DOWNDRAFT/DAMAGING WIND THREATS.
This doesn't include the Chicago metro area yet....but it probably will by about the time the Hawks game starts. A "PARTICULARLY DANGEROUS SITUATION" is just that. Supercells will fire up and they will spawn tornadoes. Its not a question of if, its a question of when and where. Be safe, keep an eye to the sky and be ready to take shelter quickly (especially Don Tiny, Darkside, COF and others who live further west). If you are going to the United Center tonite, take a minute to find out where their storm shelters are, and be ready to get down to the 100 level quickly and safely if needed.
