Areas affected...northern Wisconsin

Concerning...Severe Thunderstorm Watch 128...

Valid 172007Z - 172100Z

The severe weather threat for Severe Thunderstorm Watch 128
continues.

SUMMARY...Severe threat continues with WW128.

DISCUSSION...Thunderstorm activity continues along the cold front
within WW128. A mixed mode of clusters and isolated supercells
continues. Hail around 1-1.5 inches in diameter has been reported.
The primary risk will be for large hail and damaging wind, given the
decreasing moisture with northward extent fairly marginal low-level
shear. However, a tornado cannot be ruled out, especially with any
more discrete supercell. Through time, as the front shifts eastward
the primary threat will shift to damaging wind.
