Summary:  A winter storm warning is currently in effect until 3AM tomorrow as our first significant snow event of the season is set to impact the Chicago region beginning this afternoon.  Accumulations of 2 to 6 inches will be possible, but combined with high winds and rapidly dropping temperatures, blowing snow and slick roads will also be a concern. 

Tonight:  Very windy with snow, possibly heavy at times, gradually tapering off in the pre-dawn hours.  Lows will be in the lower 20s with winds out of the northwest at 25 to 40 MPH, with gusts up to 55 possible, especially during the evening. 

Friday:  Windy and partly sunny with a chance of flurries in the morning, clearing by the afternoon.  Highs will be in the upper 20s with winds out of the northwest at 15 to 30 MPH, gusting up to 40 at times.

Friday night:  Mostly clear with lows in the lower teens and winds out of the northwest at 10 to 20 MPH, gusting up to 30 at times.
