MARYLAND — Maryland residents are expected to face dangerous heat on next week, especially on Wednesday, with heat index values forecast to climb well above 100 degrees across much of the state as a prolonged heat wave continues.
According to the National Weather Service in Baltimore/Washington, peak heat index values are expected to range from around 103 to 108 degrees across central, southern and eastern portions of Maryland. The highest apparent temperatures are forecast near Annapolis at 108 degrees, while Baltimore, Frederick, Westminster, Washington suburbs and La Plata are expected to reach around 106 degrees. Areas around Bel Air could see a heat index of 105 degrees, with Elkton reaching about 104 degrees.
Farther west, conditions are expected to be slightly less oppressive but still dangerous. Cumberland is forecast to reach a heat index of 103 degrees, while Oakland in Garrett County is expected to remain much cooler, with a peak heat index near 93 degrees.
The heat index, often referred to as the “feels like” temperature, combines air temperature and humidity to estimate how hot it feels to the human body. Values above 100 degrees can increase the risk of heat-related illnesses, especially for older adults, young children, outdoor workers and those without access to air conditioning.
Forecasters say the dangerous heat is part of a broader heat wave expected to affect much of the eastern United States through next week. Residents are encouraged to stay hydrated, limit strenuous outdoor activities during the hottest part of the day, wear lightweight clothing and check on vulnerable family members, neighbors and pets.
