A stretch of increasingly dangerous heat is expected to build across the Baltimore region this week, with temperatures climbing into the triple digits Wednesday before remaining well above normal through the end of the workweek.
The prolonged heat could send heat index values above 100 degrees, while the next meaningful chance of showers and thunderstorms holds off until the weekend.
Tuesday serves as a warm-up for what’s ahead.
Sunny skies will help temperatures climb to about 92 degrees, with light southwest winds and dry conditions making for another typical midsummer day.
Overnight lows will only fall to around 75 degrees, offering little relief from the heat.
The hottest weather of the week arrives Wednesday, when temperatures are expected to soar to around 100 degrees.
Combined with the humidity, it could feel as hot as 106 degrees during the afternoon.
Residents planning to spend time outdoors should stay hydrated, take frequent breaks in the shade or air conditioning, and limit strenuous activity during the hottest part of the day.
The intense heat continues Thursday, with sunny skies and highs near 98 degrees, followed by another hot day Friday, when temperatures again approach the upper 90s.
Overnight lows in the mid- to upper 70s will provide only limited cooling, allowing heat to build over several consecutive days.
The weather pattern begins to shift heading into the weekend.
While Saturday remains very hot, with highs around 96 degrees, the chance for afternoon and evening showers and thunderstorms increases to 50%.
Similar conditions are expected Sunday, when additional showers and thunderstorms could help knock temperatures back into the upper 80s.
Although the weekend may bring some relief from the extreme heat, anyone with outdoor plans should be prepared for changing weather conditions as scattered thunderstorms return to the forecast.
