 A few lingering showers possible through sunset, otherwise turning mostly clear overnight, and temperatures only falling into the mid-70s. Your Monday will feature a hot day, highs near 100 degrees, with heat index values as high as 110, and a chance for some afternoon showers and storms, some of which could be strong to severe.
