 Photo, via Twitter, from Perry, Iowa. This is why you should shelter as it is was a tornado.

This is a "particularly dangerous situation" watch for 100 mph wind gusts and "a couple of tornadoes." It is expected to sweep across the Chicago area between 3 and 3:30pm. 

Ahead of the derecho, we strongly recommend these preparations:
In addition, fill your automobile's fuel system. Charge your smartphone and laptop, but take them off the charger before the storms arrive as power fluctuations can damage them.

Timing for Chicago area. Power failures LIKELY. One computer model forecasts 98 mph wind gusts in Chicago.

It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches. Power outages may occur in this areas. Deep blue is 0.1 to .25 inc
