A mostly cloudy and cool evening is on tap across the area with temps mainly in the 40s. Temps will then drop further overnight into the 30s. Locations that see breaks in the clouds will drop further with some patchy frost and patchy fog potential.
While cloud cover will be a factor, temps will still drop down into the 30s in most locations tonight, with even colder temperatures east of Springfield. Those with sensitive outdoor plants will need to take proper precautions.
