statute miles east and west of a line from 80 miles north northeast
of Mount Clemens MI to 25 miles south southwest of Dayton OH. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU1).

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.

AVIATION...A few severe thunderstorms with hail surface and aloft to

cumulonimbi with maximum tops to 500. Mean storm motion vector
