ST. LOUIS, Mo. — There is a thunderstorm watch for Pike and Montgomery Counties in Missouri until 6:00 p.m. Strong scattered thunderstorms in northwest sections of the St. Louis region should slide southeast through the afternoon.

Sunday and Monday’s forecast will be mostly sunny, hot, and humid. Highs 93° to 95° with an isolated heat-driven thunderstorm possible. Lows from 74° to 76°.
