Areas affected...central Minnesota into west-central Wisconsin

Concerning...Severe Thunderstorm Watch 355...

Valid 192056Z - 192300Z

The severe weather threat for Severe Thunderstorm Watch 355
continues.

SUMMARY...Large hail up to golf-ball size and damaging wind gusts
will remain the primary hazards as storms continue to spread
southeast across the watch area this afternoon into evening.

DISCUSSION...As of 20:45 UTC, mosaic radar data indicated a loosely
organized cluster of thunderstorms across Otter Tail, Wadena, and
Cass Counties with more intense, semi-discrete storms noted in Mille
Lacs and Kanabec Counties. The semi-discrete storms appear to be
located immediately downstream from a weak surface low, where
low-level convergence and vertical shear are likely being maximized.

Latest objective analysis suggests that the inflow air mass to these
storms remains moderately unstable with MLCAPE of around 1000 J/kg,
with increasing bulk-shear magnitudes with southward extent across
the watch area. As such, the greatest potential for large hail up to
golf-ball size is expected with the more discrete storms mentioned
above, which are in closer proximity to the stronger vertical shear.

Latest short-term model guidance continues to suggest an increased
risk for damaging winds evolving late this afternoon into evening
from the vicinity of the St. Croix River into portions of
west-central WI as storms consolidate in to clusters or line
segments.
