Temperatures Tumble for the Begining of December

If you were out today you know that it was much warmer today, then in the past few days. Temperatures this afternoon reached 47° in Rockford, and Savanna was able to hit 50° before the clouds moved in. Unfortunately, the warmth won't last with our next cold front on the way, and temperatures will tumble Sunday afternoon into Monday. Sunday morning will see a mild start with temperatures in the mid 30s, but with the passage of a cold front Sunday morning, temperatures will fall into the mid 20s by the early evening with overnight lows in the teens. Monday marks the first day of December as well as the start of meteorological winter, and it will surely feel like it. Temperatures on Monday will struggle to hit 20° by the afternoon despite plenty of sun. Winds will increase behind the front as well, with gusty north winds for Monday afternoon. However, on the bright side, temperatures will rebound back into the 30s by the middle of the week, and then we will be back to average and above by next weekend.
If the current pattern holds, it looks like the first couple weeks of December will be fairly mild.
