Crazy weather in Champaign-Urbana

The weather in Champaign-Urbana is totally crazy. Today started with a lot of rain/cloud etc, and remained cloudy. But right when I thought it would end up as one of those cold-rainy-windy days, it became sunny in the afternoon. This reminds me how I was duped last year by the sunny sky, which turned into torrential rains within 10 minutes, and left me all soaked up in my best outfit.
