Chicago weather: Mostly sunny and cool

If you're traveling to the 2015 LION Summit, you might be wondering just how heavy of a sweater to bring.

If you're traveling to the 2015 LION Summit, you might be wondering just how heavy of a sweater to bring. Or, if you're like me and coming from someplace where it'll be 102 degrees the day the conference kicks off, you're curious if you'll need a new parka.

The forecast for the end of the week is fairly mild: highs of 66 degrees, and lows of about 54, with the skies shifting from sunny on Thursday turning to partly cloudy over the weekend. Chances of rain are just 10 percent, although somewhat higher at 20 percent on Friday. And those notorious winds? They'll range from 11-14 mph.
