What happened

The episode as NWS LWX wrote it up.

High pressure in combination with southerly winds brought hot, hazy, and humid conditions to the Mid Atlantic region between June 27th and 30th. High temperatures soared into the lower 90s and heat indices reached into the lower 100s through the period. Two deaths in Baltimore were related to the heat wave. On the 30th, a 34-year-old man died from a combination of heart problems, cocaine use, and exposure to the heat. On July 1st, when temperatures still reached near 90 degrees, a 51-year-old man died from heat exhaustion and heart problems.
