Areas affected...Western Great Lakes

Concerning...Severe Thunderstorm Watch 295...

Valid 310117Z - 310245Z

The severe weather threat for Severe Thunderstorm Watch 295
continues.

SUMMARY...Severe threat will increase across the western portions of
ww295 over the next hour.

DISCUSSION...Strong large-scale support is spreading across the
upper MS Valley ahead of short-wave trough and associated 95kt 500mb
speed max approaching northwest IA. High-level diffluent flow aloft
and ample reservoir of buoyancy across WI suggest squall line over
eastern MN will continue to advance east. Several fast-moving
bow-type features are noted along this linear MCS and damaging winds
can be expected with these features. Severe threat will increase
across western portions of ww295 over the next hour or so.
