The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Eastern Iowa
  Northern Illinois
  Far Northeast Missouri
  Lake Michigan

* Effective this Friday night and Saturday morning from 655 PM
  until 200 AM CDT.

* Primary threats include...
  Scattered damaging winds and isolated significant gusts to 80
    mph likely
  Scattered large hail and isolated very large hail events to 2
    inches in diameter possible
  A tornado or two possible

SUMMARY...Ongoing line of showers and thunderstorms is expected to
progress quickly northeastward/eastward over the next several hours.
Very strong low- to mid-level wind fields exist, supporting the
potential for strong gust with any deeper, more sustained storms.
Some isolated hail is possible as well. Dry low-levels are expected
to keep the tornado potential very low, although still none zero
given the strongly sheared environment.

The severe thunderstorm watch area is approximately along and 50
statute miles north and south of a line from 25 miles southwest of
Cedar Rapids IA to 45 miles east northeast of Marseilles IL. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU5).

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
