Baltimore-area weather: It feels as hot as 103 degrees as heat alert continues Wednesday

It felt as hot as 103 degrees around the Baltimore region Wednesday afternoon, and could get hotter as temperatures surge toward the upper 90s amid high humidity.

A “Code Red” heat alert is in effect in Baltimore on Wednesday, and Dr. Leana Wen, the city’s health commissioner, extended that warning through Thursday.


The National Weather Service meanwhile issued a heat advisory along the Interstate 95 corridor through 8 p.m. Wednesday, warning of health hazards.

“The combination of high temperatures and high humidity will create a situation in which heat illnesses are possible,” forecasters wrote. “Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening.”

As of 2 p.m., it was 95 degrees at Baltimore-Washington International Thurgood Marshall Airport and 96 degrees at the Inner Harbor. In both places, the heat index reached 103.

On Tuesday afternoon, the heat index approached 110 degrees Tuesday afternoon in Baltimore, because of the hot, humid air flowing into the Baltimore region this week.

The heat peaked just before 4 p.m. Tuesday at Baltimore-Washington International Thurgood Marshall Airport, with 95-degree heat and high humidity making it feel like 103 degrees, according to the weather service. At the Inner Harbor, temperatures reached 97 degrees with a heat index as high as 107.

Baltimore Health Commissioner Leana Wen said the city would open the Northern, Southern, Northwest and Southeast community action partnership centers as cooling centers both days from 8:30 a.m. to 4:30 p.m. Other areas, including Carroll County and Anne Arundel County, also announced plans to open cooling centers.

Heat in the lower 90s and high humidity are forecast to continue into Thursday, before a cold front passes through, likely bringing storms and heavy rain. More chances for rain and storms and highs in the lower 80s are forecast Friday.

The surge of late summer heat comes after what has already been a warm month of August, and a seasonably hot summer. Average temperatures in June and July were about normal, while August heat was already running nearly 3 degrees above average at Baltimore-Washington International Thurgood Marshall Airport.

Still, the region has not actually hit triple-digit temperatures this summer, coming 1 degree away from 100 degrees on July 3. BWI has reached 100 degrees only once in the past six years, on July 25, 2016.
