***Hot and humid for much of the Central U.S. through Saturday***
***More showers and storms for the Desert Southwest***
Another hot and humid day can be expected on Saturday from the Upper Midwest to the Central Plains as a summer-like ridge pattern tries to hold strong to close out the month of August. Heat advisories are in effect for parts of Missouri, eastern Kansas, and for southern Illinois and adjacent states on Saturday. High temperatures are forecast to rise well into the 90s to around 100 degrees, and lows only falling into the 70s along with elevated humidity levels.
Cooler and more pleasant conditions are expected for Labor Day with the passage of a cold front.
Elsewhere across the continental U.S., scattered showers and storms can be expected for the Desert Southwest and into the Inter-Mountain West with lingering monsoonal moisture in place. Localized heavy rainfall will be possible, along with isolated flooding issues.
An organized area of moderate to heavy rainfall can be expected from the northern Great Lakes to New England as a surface low tracks eastward across southern Canada, and another area of organized rainfall is likely with the passage of the cold front across the Upper Midwest.
Dry conditions should continue for the next few days across the Southern Plains.
