The National Weather Service has issued a heat advisory for Monday, Aug. 18, 2025 from noon until 7 p.m., as triple-digit heat indices will stick around for at least another day.

The advisory covers several area counties including Saline, Chariton, Cooper, Howard, Johnson, Pettis, Benton, Macon, Moniteau, Morgan, and Randolph counties. Heat index values of up to 106 are expected, as hot temperatures and high humidity may cause heat illnesses.

Community buildings across the area are doubling as cooling centers. In Marshall, the Salt Fork YMCA will have its lobby open as a cooling center during its normal hours, closing at 9 p.m. Mondays through Thursdays, 7 p.m. on Fridays, and 6 p.m. on the weekends.
