of northern Minnesota, and it eventually may reach western Lake
Superior and northwest Wisconsin. Swaths of wind damage can be
expected this morning even while this fast-moving wind-producing

Additionally, a tornado or two cannot be ruled out with embedded
circulations within the line.
The severe thunderstorm watch area is approximately along and 90
statute miles north and south of a line from 70 miles north
northwest of Brainerd MN to 40 miles south southeast of Grand Marais
MN. For a complete depiction of the watch see the associated watch
outline update (WOUS64 KWNS WOU0).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.
