Clearer, Cooler Saturday

Heat Builds Into Next Week
Sunday warms to about 88 degrees, followed by highs near 91 Monday and 92 Tuesday. The National Weather Service expects hot, humid conditions to continue, with heat indexes potentially reaching the upper 90s or lower 100s.
Thunderstorm chances increase again by midweek, with a 40% chance of showers and thunderstorms Wednesday and a 30% chance Thursday. No watches, warnings or advisories are posted for Baltimore, but anyone heading outside Friday should keep lightning in mind and have a backup plan for the afternoon.
