Baltimore, Maryland– By early Tuesday afternoon, triple-digit temperatures are expected to scorch Baltimore, and a hazardous heat index of 105° is threatening infrastructure and public health throughout Central Maryland.
On Tuesday, July 29, high temperatures in Baltimore are expected to reach 101°F, but when humidity rises, the temperature will feel more like 105°. After 2:00 p.m. on Tuesday, there is a remote possibility of thunderstorms, which could provide momentary respite but also pose unexpected risks to travelers and outdoor workers. The heat will not be dispersed much by light winds.
Anyone who intends to spend time outside should limit their exposure during the hottest parts of the day and stay hydrated. Steer clear of physically demanding activities, particularly along busy thoroughfares like Interstate 95, where temperatures may rise even further. Tuesday night is still at danger for heat, with lows of about 83°F.
The trend changes by Wednesday. After 2:00 p.m., there may be isolated storms in Baltimore, with showers and thunderstorms spreading farther throughout the night into Thursday. With highs hovering above 102°F and storm chances rising to 80% by midweek, heat is still a problem.
