I will attest to all the experts that frosted corn will come back. We had some two years ago that came back, but it is never the same. I think if you have dead leaves on the ground after the frost_freeze you are looking at 10-40% in yield loss. Good conditions the rest of the way may make the loss seem less, poor conditions may amplify the loss, but rest assured if the crop goes on to make 160 it would have been better. I showed 21 degrees at 7 am in southwest Il. Thats enough to freeze the ground. With highs today in the low 30's and teens tonight any corn in this area to the north will freeze, even under ground. With below normal temps and chances of rain predicted through all of next week and saturated soils in most of central Il and Northern Il look for delayed planting thoughts to start energizing the corn market. The last few years most Il corn was planted by the 3rd or 4th week of April with quite a bit being planted next week. We will be behind that by a bunch unless the weather turns. I don't know much about wheat so I'll leave that to someone else, but it can't be good.
