Powerhouse Cold Front To Send Temps Crashing From Mid-Afternoon into Evening

A very strong cold front will sweep across the area this afternoon into this evening. Winds will shift to northwest and temperatures will plummet behind the front, possibly as much 15 to 20 degrees in just about an hour's time. Some showers and thunderstorms will accompany the northwest winds and much colder temperatures behind the front. The front should sweep through Rockford by mid to late afternoon and across the Chicago area toward evening rush hour and across northwest Indiana during the early evening.
