CENTRAL ILLINOIS -- No warmth is in sight across central Illinois with chilly temperatures predicted to last through the weekend.
StormCenter17 Meteorologist Adam Del Rosso says a big southward dip in the jet stream, also known as a trough, is to blame for the cool pattern.
He says high temperatures Friday and Saturday only make it into the 40s. However, more of a focus is on Saturday morning when lows will drop into the upper 20s, causing the National Weather Service to issue a Freeze Watch.
By Sunday, temperatures rebound a little into the upper 50s. On average, highs for mid April are supposed to be in the mid 60s.
