The Weather Front On-Line
Across the Corn Belt, hot weather persists in the Ohio Valley, but cool air covers the upper Midwest. Thunderstorms in the vicinity of a cold front stretch from the lower Great Lakes region into the middle Mississippi Valley.
Across the Corn Belt, a band of widely scattered but highly beneficial showers stretches from South Dakota into northern Ohio. However, unfavorably hot conditions persist in much of the Midwest. Monday’s maximum temperatures will again approach, reach, or exceed 100° in the southwestern Corn Belt.
On the Plains, favorably cooler weather prevails in the Dakotas.
Across the Corn Belt, favorably cooler weather prevails, although heat lingers across westernmost areas. In Fort Wayne, Indiana, a record-setting streak of highs of 90° or greater has ended at 22 consecutive days (June 27 –July 18).
Across the Corn Belt, devastatingly hot, dry conditions persist in most areas, although showers and thunderstorms are spreading across the far upper Midwest (e.g. the Dakotas). On July 15, at least 80% of the topsoil moisture was rated very short to short in all Midwestern States except Minnesota (53% very short to short) and North Dakota (62%).
Substantially cooler air will overspread the Plains and the Midwest during the weekend.
By early next week, near- to below-normal temperatures will cover all areas east of the Rockies, except for a return to hot weather on the northern High Plains.
Across the Corn Belt, showers and thunderstorms are rolling across the northern edge of a ridge of high pressure that continues to produce crop-damaging heat. On the 4th of July, high temperatures reached or exceeded 100° across the majority of the Corn Belt, severely stressing reproductive corn and soybeans.
Across the Corn Belt, unfavorably hot, dry weather covers the Midwest. By July 1, one-fifth to one-half of both corn and soybeans were rated very poor to poor in Indiana (50 and 43%, respectively, for corn and soybeans), Missouri (48 and 49%), Illinois (33 and 31%), Michigan (28 and 27%), Ohio (26 and 30%), and Wisconsin (24 and 25%).
On the Plains, hot, mostly dry weather prevails.
Across the Corn Belt, a record-shattering heat wave continues to trim yield prospects for reproductive corn and soybeans across drought-affected southern and eastern portions of the region.
