Forecasters are watching for development of potentially severe thunderstorms across Maryland late Thursday, though the strongest chances for severe weather were expected in Southern Maryland.
Warming temperatures are expected to fuel the atmospheric instability, according to the National Weather Service's Storm Prediction Center. Temperatures reached 84 degrees at Naval Air Station Patuxent River in St. Mary's County by 1:30 p.m., while it was 77 degrees at BWI Marshall Airport.
An area of Southern Maryland and the lower Eastern Shore, along with parts of Central Virginia, is expected to have a 15 percent chance of severe damaging wind gusts. In the Baltimore area, storms are considered less likely to be severe.
AccuWeather.com forecasters expect the storms to remain isolated across an area from West Virginia to the Delmarva, remaining south of the Baltimore and Washington areas.
The weather service's Baltimore/Washington forecast office expects a 30 percent chance of isolated storms Thursday evening.
Across the nation, the severe weather season has been off to a relatively quiet start. The number of tornadoes was at a 20-year low earlier this week.
But at least six people were killed when a powerful tornado ripped through a neighborhood including a Habitat for Humanity low income housing area in the north Texas town of Granbury on Wednesday, marking the deadliest severe storm outbreak in the United States this year.
