DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1125 AM CDT THU SEP 04 2014
VALID 041630Z - 051200Z
...THERE IS A SLGT RISK OF SVR TSTMS THROUGH EARLY TONIGHT FROM
CENTRAL/NRN WI TO PARTS OF UPPER AND LOWER MI...
...SUMMARY...
A FEW SEVERE STORMS WITH DAMAGING WINDS AND LARGE HAIL ARE EXPECTED
TO MOVE FROM NORTHERN WISCONSIN INTO UPPER MICHIGAN AND NORTHERN
LAKE MICHIGAN TODAY. ISOLATED STRONG TO SEVERE STORMS MAY ALSO
DEVELOP AGAIN THIS AFTERNOON OVER WESTERN AND CENTRAL
WISCONSIN...AND PERHAPS SOUTHWESTWARD INTO IOWA AND THE CENTRAL
PLAINS.
...WI/MI...
A LONG-LIVED CLUSTER OF SEVERE STORMS IS TRACKING EAST-
SOUTHEASTWARD ACROSS NORTHERN WI. THESE STORMS ARE EXPECTED TO MOVE
INTO NORTHERN LAKE MI BY 18Z...AND THEN PROBABLY WEAKEN AS THEY
PROGRESS INTO NORTHERN LOWER MI THIS AFTERNOON. DAMAGING WINDS AND
HAIL WILL REMAIN A THREAT WITH THESE STORMS FOR A FEW MORE HOURS.
IN THE WAKE OF THIS THUNDERSTORM COMPLEX...RAPID DAYTIME HEATING AND
DESTABILIZATION WILL OCCUR OVER PARTS OF EASTERN MN AND NORTHERN WI.
AT THE SAME TIME...THE MID LEVEL CAPPING INVERSION WILL STRENGTHEN.
WATER VAPOR IMAGERY DOES NOT SHOW ANY OBVIOUS SHORTWAVE TROUGHS
APPROACHING THE AREA...AND THE MECHANISM FOR CONVECTIVE
RE-DEVELOPMENT IS HIGHLY UNCERTAIN. NEVERTHELESS...THE POTENTIAL
FOR ISOLATED STRONG TO SEVERE STORMS IN THE AXIS OF HIGH INSTABILITY
AND FAVORABLE SHEAR ACROSS WI IS SUFFICIENT TO MAINTAIN THE ONGOING
SLIGHT RISK. STORMS THAT FORMS IN THIS REGION WILL BE CAPABLE OF
LARGE HAIL AND DAMAGING WINDS.
FARTHER SOUTHWEST...A LOW RISK OF AN ISOLATED THUNDERSTORM OR TWO
REMAINS ALONG AN AXIS FROM SOUTHWEST WI INTO THE CENTRAL PLAINS.
ANY STORM THAT FORMS COULD PRODUCE GUSTY WINDS.
