Today will feature the last day of below-average temperatures, at least for a while. Most locations will struggle to get much above 40 degrees this afternoon, and overnight lows will fall into the 20s and teens.
Warmer weather is on the way! Afternoon temperatures in the 50s and 60s will be common by the weekend into next week. Compare that to just five days ago when the high temperature in Springfield was 17 degrees!
Good news for those of you who are sick of the cold! Signals strongly favor above-average temperatures in the Feb 11th-17th period. For reference, average high temperatures for this time of year are in the 44 to 50 degree range.
