Baltimore, Maryland – Triple-digit heat is set to roast Baltimore by early Tuesday afternoon, with a dangerous 105° heat index threatening health and infrastructure across Central Maryland.

A slight chance of thunderstorms will follow after 2 p.m. Tuesday, which may offer brief relief but could create sudden hazards for travelers and outdoor workers.
