AREAS AFFECTED...NE IA...SE MN...WRN WI

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 280104Z - 280300Z

ISOLATED SEVERE THUNDERSTORM DEVELOPMENT WILL LIKELY CONTINUE OVER
THE NEXT FEW HOURS ACROSS FAR NE IA...SE MN AND WRN WI. LARGE HAIL
AND ISOLATED WIND DAMAGE WOULD BE THE PRIMARY THREATS.

LATEST SFC ANALYSIS SHOWS A MOIST AXIS EXTENDING NWWD ACROSS WRN IA
INTO SE SD. STRONG INSTABILITY IS LOCATED ALONG THE MOIST AXIS WITH
STORMS INITIATING ALONG THE INSTABILITY GRADIENT IN NERN IA.
ADDITIONAL STRONG STORMS ARE ONGOING IN WEAKER INSTABILITY ACROSS
CNTRL WI. THE STORMS ARE FORMING BEHIND A SHORTWAVE TROUGH AND MAY
INCREASE IN COVERAGE GRADUALLY THIS EVENING. REGIONAL PROFILERS SHOW
MODERATE VERTICAL SHEAR PROFILES ACROSS THE REGION ASSOCIATED WITH A
MID-LEVEL JET MAX OVER SRN WI. THIS COMBINED WITH STEEP LAPSE RATES
SUGGEST ISOLATED SUPERCELLS WILL BE POSSIBLE WITH A POTENTIAL FOR
LARGE HAIL AND WIND DAMAGE OVER THE NEXT FEW HOURS.
