Expect record-breaking warmth again on Thursday across parts of Maryland.

Temperatures could reach 93 degrees in the Baltimore region as a heat wave settles over much of the eastern United States, according to the National Weather Service. The record high for April 16 in Baltimore is 90 degrees, set in 2012.

Springtime has seen stubborn high pressure that has been largely undisturbed due to a lack of rain, said Samantha Timmers, a meteorologist for the weather service’s Baltimore/Washington office.

“And when that happens, it just gets warmer and warmer,” she said.

The Baltimore area broke an 85-year record Wednesday as the temperature reached 91 degrees. It was the highest recorded on April 15 in the city since 1941.

People working outdoors should be extra cautious as dry heat can sneak up on you, Timmers said. It’s important to stay hydrated.

The weather service also warned about critical fire conditions across parts of Maryland due to dry air and wind gusts of 20 to 25 mph. Wildfires could spread rapidly Thursday afternoon.

People should be cautious while disposing of cigarette butts, matches and other flammable items. Dr grasses, dead leaves and other tree litter could easily ignite and spread fire, according to the weather service.

Temperatures will hover in the high 80s Friday and Saturday, with some chances of showers starting in the evening into Sunday. The rain will cool down the region, with temperatures expected to drop back to the 60s by Monday.
