(WAND) -- After a sunny and hot start to the week, rain and cooler temperatures will be here to end it.
Meteorologist Adam Del Rosso says highs will reach close to 90° Monday through Wednesday with plenty of sunshine helping to dry out the corn crop some more before harvest.
By Thursday, temperatures will cool into the lower 80s as rain chances pick up. Del Rosso says that is thanks to the large ridge of high pressure breaking down allowing a cold front to push closer.
Ag Expert Dave Brown says harvest has started in some central Illinois areas, but will not see wide spread activity for another week.
"Corn is now down below 30% moisture, but it's still expensive to dry down to 15%, which is required for short term storage," Brown says. "90° temperatures are good for the drying of corn, and Sunday was an excellent day for drying because of low humidity and wind. Right now, farmers need low humidity, wind and heat."
Brown tells WAND soybeans are about two weeks off before any harvesting. He reminds those driving in the country in weeks to come to please dry safely with operations picking up.
