A few isolated showers across far northern MO this morning will likely do little to mitigate the dangerous heat that continues through early Tuesday. Temperatures approach 100°F in many places with heat index values from 110°F to near 120°F. Overnight lows Monday into Tuesday only dip to ~75°F-80°F. A small chance for storms is possible across central MO later this afternoon into the evening. Relatively cooler temperatures return Tuesday.
