Delmarva will sizzle but not sweat this week

Summer weather is here for the remainder of the workweek on Delmarva.

The mid-Atlantic region is being hit by a Bermuda high, which is a high pressure system that gets caught between the island of Bermuda and the mainland United States, according to Wayne Albright, a meteorologist with the National Weather Service in Wakefield, Virginia.

"We have high pressure off the coast and a southwest wind," he said. "This is typical weather for the summer."

However, Albright said the humidity will not be like a typical summer heat wave. He said dew points this week will be in the low to mid 60s, meaning the humidity will not be as oppressive as in a real summer heat wave.

"This would be a typical July day," he said. "But for mid-May, this is above normal weather."

Sussex, Somerset, Wicomico and Worcester counties are all under an air quality alert for Wednesday, meaning the air quality may approach or exceed unhealthy levels. Individuals with respiratory or heart ailments, older adults and children should avoid being outside for too long, the warning said.

The highs in Wicomico, Somerset and Sussex counties are expected to reach the high 80s to low 90s Wednesday and Thursday and the high 80s on Friday.

The temperatures in Wicomico County may approach a record high of 90 degrees, set in 1944, for Wednesday, May 17, Albright said.

In Worcester and Accomack counties, highs are expected to be in the mid-80s to low 90s through the rest of the workweek.

Northampton County will see temperatures in the mid-80s Wednesday and Thursday and low 80s Friday.

There is no threat of severe thunderstorms associated with this high pressure system, Albright said, but he could not rule out a thunderstorm Friday.

For context, the temperatures for the rest of the week in Philadelphia, Baltimore and Washington, D.C., will be in the high 80s to mid-90s for the remainder of the workweek.

This weekend, though, should bring relief for Delmarva.

It will be cooler, with highs in the low to mid-70s and partly cloudy, Albright said, and it will be cooler at the beach, with strong winds and temperatures in the mid-60s in Ocean City.

"There is a a very low probability for rain, so the weather will be closer to normal," he said. "A far cry from today and tomorrow."
