The heatwave wiped out old records on August 25 as the mercury soared:

The intense heat is thanks to a broad ridge of high pressure stretching from the southern Plains into the Mid-Atlantic. Underneath it, hot southerly breezes and late-August sunshine will heat temperatures well into the 90s to near the century mark today. Add in oppressive humidity, and it could feel as hot as 110 degrees from Kansas City, Mo., to St. Louis, Memphis, Tenn., and Little Rock, Ark.

Excessive Heat Warnings remain in place from eastern Missouri into south-central Illinois, with Heat Advisories surrounding the warnings from eastern Kansas into southwestern Indiana and western Kentucky, including St. Louis, Kansas City, Mo., Springfield, Ill., and Paducah, Ky.

Fortunately, relief is in sight: thermometers will fall back to seasonal levels by the end of the week.  Some relief from the extreme heat will arrive in the form of a weak cold front supplying showers and a few thunderstorms across northern Missouri and central Illinois on Wednesday. Temperatures will be slightly cooler, in upper 80s and lower 90s, on Wednesday. Even better, residents in the Mid-Mississippi Valley and Mid-South will be able to enjoy Labor Day parties and barbecues in seasonably warm 80s to near 90 degrees.

Heat stroke claims more than 600 lives in the U.S. every year. Know the signs and what to do when the mercury soars to dangerous levels.
