(WAND) -- A strong cold front is set to bring much colder air to central Illinois this week.

Meteorologist Adam Del Rosso says it's possible some places see their first frost of the season with lows in the 30s. However, he says that won't happen until the end of the week with summer-like warmth still in place Monday and Tuesday.

Del Rosso says highs temperatures will reach the mid 80s until Wednesday when the front arrives. By Thursday and Friday, highs will only hit the 50s with overnight lows generally in the 40s. On average, lows hit the 30s for the first time in the season around October 7, so this is not abnormal.

He says that same cold front will bring the best chance for rain Wednesday with around 1.00" expected. Aside from that hiccup, Del Rosso says harvest should continue smoothly this week.
