Following a week that saw morning lows plummet into the teens and 20s for large portions of the Plains and Midwest, expect to see a dramatic warm-up across much of the U.S. and parts of Canada over the next week to 10 days.
High temperatures will be in the low to upper 70s through Easter Sunday for the Central Plains. The upper Midwest will see 50s to 60s, with slightly warmer temperatures in the 60s to low 70s for the lower Midwest, and 70s to low 80s across the Deep South.
By Wednesday, April 23rd, look for all areas east of the Rockies to warm up another couple of notches, with 80s to low 90s in the Plains, 70s to low 80s for the Midwest, and 80s to low 90s across the Deep South.
Overall, high temperatures will average 3 to 6+ degrees F above normal in these major corn production areas. Soil temperatures will respond accordingly... as will farmers and producers who have been cooped up indoors after a long, cold and snowy winter.
As the warm-up evolves, there will be a series of low pressure systems that become organized over the Central Plains that eventually track eastward. These storms will produce thunderstorms, some potentially severe, as they push from the eastern Plains and across the Mississippi Valley states.
The Ohio and Tennessee valleys and Deep South will also feel the effects of these systems. The first of these develops on Easter Eve and heads east.
A second storm develops on the 23rd and pushes across the central U.S. on the 24th and 25th.
These storms are likely to slow planting for a day or so due to wet field conditions before the warming allows equipment to return to the fields.
Look for Nebraska, Kansas, Missouri, Illinois, Indiana, Kentucky, Ohio, and Tennessee corn planting to increase dramatically by next Sunday, April 27th.
