Topsoils still damp in western Corn Belt
Eyewitness reports indicate some field activity began in central Iowa yesterday afternoon as the topsoils continue to slowly dry in the central and eastern sections of Iowa as well as western and central Illinois.
Today near-record warmth with temperatures near or above 90 are forecast for western and central Iowa and 80s to near-90-degree temperatures are forecast for eastern Iowa and Illinois as well.
Sunny conditions, a southerly breeze, and warm temperatures are all combining to help dry the soils. Even so, it still looks like there are some very moist topsoils in parts of eastern Iowa and western Illinois. A cold front will move southward across the northern Corn Belt tonight and become stationary across northern Missouri and central Illinois later tomorrow cooling temperatures several degrees for the middle to latter part of the week.
Scattered light showers are possible along this frontal boundary tonight across western and central Iowa with a much better chance of showers and thunderstorms tomorrow night along and north of the frontal boundary. Later this week and over the weekend, this weak frontal boundary will begin to lift northward bringing scattered showers and thunderstorms over a large section of the Corn Belt states.
We are estimating that beginning on Wednesday night and the latter part of the week that more than 50% of the region will receive 0.25" to 0.50" rains with locally heavier amounts particularly along this frontal boundary from southern Iowa and northern Missouri eastward through central Illinois and Indiana into Ohio.
More rain is forecast next week. A discussion with some agronomists suggests that modern planting technology can plant more than 10% of the corn crop per day.
If true, we might see 40% of the crop planted this week. We have to admit this is a real guess right now. However, rain forecast for this next weekend and early next week could slow the planting progress once again.
