(WAND) -- Much colder air is set to move into central Illinois by the end of the week.

Meteorologist Adam Del Rosso says highs through Tuesday will remain in the 50s, but drop into the 40s for the rest of the week. By Saturday, Del Rosso says high temperatures won't even make it out of the 30s. Overnight lows will be well below freezing in the low 20s with wind chills in the teens.

Ag Expert Dave Brown says this is the time to check all equipment and vehicles to make sure they are ready for winter's colder temperatures. He recommends checking batteries and anti-freeze levels.

As for precipitation, rain will fall once again Monday afternoon and evening before a lull through the middle of the week. Del Rosso says a rain/snow mix is possible Thursday night with more flurry chances over the weekend. However, he cautions that there is a lot of uncertainty still in that part of theĀ forecast this far out.
