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

1 inch. Extreme turbulence and surface wind gusts to 60 knots. A few
