AREAS AFFECTED...WEST CENTRAL INTO CENTRAL WI

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 140106Z - 140230Z

THUNDERSTORMS...WITH AN ATTENDANT SEVERE POTENTIAL...EXPECTED TO
INCREASE IN AREAL COVERAGE BY MID EVENING /AROUND 03Z/ ACROSS WEST
CENTRAL WI THEN SPREAD ESEWD.  WW MAY BE REQUIRED NORTH OF WW 178
FOR PARTS OF CENTRAL WI.

LATEST LIGHTNING DATA/SATELLITE IMAGERY SUGGESTS CONVECTIVE ACTIVITY
CURRENTLY SPREADING EWD ACROSS ERN ND/NERN SD IS ASSOCIATED WITH
LEADING EDGE OF DEEPER LARGE SCALE ASCENT WITH SRN CANADA/ND SHORT
WAVE TROUGH.  WEAK INSTABILITY OVER ERN ND SHOULD LIMIT THE SEVERE
THREAT WITH PRESENT ACTIVITY OVER THAT REGION. 

AT 00Z...A WARM FRONT EXTENDED FROM EAST CENTRAL MN SEWD ACROSS NRN
IL/NRN IND.  STRENGTHENING SSWLY LLJ ACROSS ERN IA/IL INTO CENTRAL
WI WILL PROVIDE A FEED OF GREATER MOISTURE/INSTABILITY TO MAINTAIN
STORMS ONCE THEY DEVELOP ALONG/N OF WARM FRONT INTO CENTRAL WI. 
THUNDERSTORMS ARE EXPECTED TO INCREASE IN COVERAGE OVER WEST CENTRAL
WI /POTENTIALLY ERN MN/ BY 03Z AS THE ASCENT NOW LOCATED OVER ERN
ND/SD ENCOUNTERS THE GREATER INSTABILITY FARTHER EAST. HAIL SHOULD
BE THE PRIMARY THREAT AS MUCH OF THIS EXPECTED NEW DEVELOPMENT WILL
LIKELY BE ELEVATED.
