Wet, cooler weather coming to Midwest crops
A spotty rain activity pattern in southwest Iowa, particularly around the Omaha, Nebraska, area on Sunday, is expected to occur in northeast Iowa today.
Moisture relief is needed in all parts of the state of Iowa and northern Illinois.
In northeast Iowa, a wave of low pressure is forecast to interact along this frontal boundary, particularly this afternoon and evening. Scattered thunderstorms moving southeast from southwestern Minnesota early Monday should move into this unstable zone this evening. These storms are forecast to move to the southeast and expand across portions of north-central and eastern Iowa into northwestern Illinois overnight.
Rainfall amounts could be in the 0.25"-1.00" range with 30% to 50% coverage across this region. Cooler air will follow behind these storms tonight, bringing several days of cooler weather in the 70s and 80s, across a large section of the western and central Corn Belt states including Iowa and Illinois through the middle of this week.
Isolated storms are forecast for portions of eastern Nebraska and western Iowa, during the middle of the week.
More significant storms are forecast for the western and central Corn Belt states, late this week and weekend.
Last week's U.S. Drought Monitor began to indicate that abnormally dry conditions were beginning across northwest Missouri and south-central Iowa and north along the Missouri River Valley between Omaha and Sioux City.
On Sunday, heavy rain developed along and north of a nearly stationary frontal boundary across Missouri and southern Iowa. Sunday's widespread rain over the south-central and southeast sections of Iowa ended this brief, abnormally dry area. Radar-estimated rainfall indicated 0.25"-1.00"+ rains with good coverage in south-central and southeast Iowa yesterday.
