AREAS AFFECTED...SOUTHERN MINNESOTA AND CENTRAL/SOUTHERN WISCONSIN

CONCERNING...SEVERE THUNDERSTORM WATCH 733...

VALID 231250Z - 231445Z

SLIGHTLY ELEVATED TSTMS EXPECTED TO CONTINUE MOVING/DEVELOPING EAST
SOUTHEAST ACROSS PARTS OF SRN MN AND CNTRL/SRN WI THROUGH
MID-MORNING.  AN ADDITIONAL WW NOT EXPECTED.

TSTMS SHOULD CONTINUE TO FORM NORTH OF STATIONARY FRONT NOW
EXTENDING FROM ERN SD EAST-SOUTHEAST INTO NRN IL.  ACTIVITY WILL BE
SUPPORTED BY 30+ KT WSWLY LLJ ASSOCIATED WITH ENTRANCE REGION OF UPR
JET STREAK CROSSING THE UPR GRT LKS.  AREA VWP AND PROFILER DATA
SHOW THAT DEEP WIND PROFILES REMAIN FAVORABLE FOR SUSTAINED
STORMS/SUPERCELLS.  HOWEVER...12Z RAOBS AT ABR AND RAP SUGGEST THAT
SUBSTANTIAL EML WILL CONTINUE TO SPREAD FROM W TO E ACROSS SRN MN/IA
THROUGH THE MORNING.  THIS...COUPLED WITH EXISTING LOW LEVEL
CIN...SHOULD KEEP STORMS IN THE REGION ELEVATED.  THE WRN EDGE OF
NEW DEVELOPMENT SHOULD SHIFT GRADUALLY EWD INTO SE MN AND WRN/SRN WI
WITH TIME.

GIVEN STRENGTH OF CLOUD-LAYER SHEAR AND INSTABILITY...POTENTIAL WILL
EXIST FOR A FEW STORMS WITH HAIL AND POSSIBLY HIGH WIND.
