High temperatures approaching 100 degrees have many people wondering about the last time this occurred. Reaching 100 degrees is a rare occurrence in central Illinois. A review of the climate record shows it has been at least several years since most locations have reached triple digits. The Champaign-Urbana area went 16 years without reaching the century mark, until a high of 100 degrees was measured on Tuesday, July 19th.
The northern Plains and upper Midwest will experience a break from hot, humid conditions, but oppressive levels of heat and humidity will persist through the weekend in most other areas from the central and southern Plains to the East Coast. Meanwhile, warm weather will temporarily affect the Far West, although cooler conditions will return next week.
