Last week sure felt like a roller coaster from summer warmth to some seeing snow in just three days! From mid 80s to low 40s for afternoon highs! Just how common is a difference like that in Chicago? Well it tends to happen annually, but rarely outside of Nov-May! #ILwx #INwx pic.twitter.com/GDtgO2fBKX

After daytime highs stay below 50° today, a clear evening with less wind will allow temperatures to tumble. This will favor frost to develop and probable that subfreezing is reached in outlying locations. For those with outdoor plants, be ready to cover or take in. #ILwx #INwx pic.twitter.com/gowIgfjxGi

While some of the area saw their first snow last week, Rockford IL officially observed their first snow (mixed with rain) early this morning. This is about two and a half weeks ahead of the normal.

The Quad Cities area saw a brief burst of snow very early this morning, while more of a light rain/snow mix observed at a few locations in north central Illinois. Precipitation will gradually end across the area by sunrise. #ILwx https://t.co/u3gs0zK30g

Record lows and record-cold highs were set across parts of the Rockies and Plains Monday. By this weekend and the first half of next week, the Northeast could get in on some of the winterlike chill: https://t.co/O2KeYEYsbE pic.twitter.com/kI7vjzZWnJ

Parts of the US were launched from #summer & straight into #winter over the weekend! Good news is, we have our winter weather expert @TomNiziol back from hibernation to break it down!
