AREAS AFFECTED...FAR SOUTHEASTERN IOWA ACROSS NORTHERN ILLINOIS
CONCERNING...TORNADO WATCH 32...
VALID 110051Z - 110145Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 32 CONTINUES.
SUMMARY...SEVERAL SUPERCELLS ON THE IMMEDIATE FRONTAL ZONE WILL POSE
A CONTINUED RISK FOR ALL HAZARDS THIS EVENING.
DISCUSSION...MULTIPLE STRONG SUPERCELLS HAVE DEVELOPED ALONG THE
FRONTAL ZONE THIS EVENING FROM EXTREME SOUTHEASTERN IA INTO NORTHERN
IL> AS OF 0045 UTC, RADAR AND SURFACE DATA SHOWS MOST OF THE STORMS
REMAIN ON THE IMMEDIATE COOL SIDE OF THE FRONT/MODIFIED OUTFLOW
BOUNDARY. TO THE SOUTH OF THE FRONT, ROBUST SURFACE-BASED BUOYANCY
AND VERY STRONG LOW-LEVEL SHEAR REMAIN IN PLACE SUPPORTIVE OF ALL
SEVERE HAZARDS.
CURRENT FORECAST GUIDANCE AND OBSERVATIONAL TRENDS SUGGEST THESE
STORMS MAY BRIEFLY BECOME SURFACE-BASED THIS EVENING AS THEY CATCH
UP TO THE SURFACE FRONT. THIS APPEARS MOST LIKELY WITH THE STORMS TO
THE SOUTHWEST OF THE MAIN CLUSTER (STARK/MARSHAL COUNTIES IL).
SHOULD THIS OCCUR, AN STP ENVIRONMENT OF 2-4 WOULD SUPPORT THE RISK
FOR TORNADOES, SOME OF WHICH COULD BE STRONG TO INTENSE, ALONG WITH
VERY LARGE HAIL.
ADDITIONAL STORMS MOVING OUT OF EASTERN MO MAY MOVE INTO SOUTHERN
PORTIONS OF WW32 THIS EVENING. THIS WOULD CONTINUE TO SUPPORT A RISK
FOR ALL HAZARDS INTO TONIGHT.
