The National Weather Service has issued a tornado watch for nearly all of Maryland, effective through 9 p.m.

Frederick County and western Maryland counties were the first to be placed under the watch at 1:30 p.m., and most of the rest of the state followed within half an hour. A tornado warning was issued for part of Amherst County in central Virginia just before 2 p.m.

A watch indicates that conditions could become ripe for tornado activity, while a warning indicates tornado activity spotted. The tornado watch does not include Worcester County on the lower Eastern Shore.

Southerly winds are helping push moisture toward an oncoming front, and strong wind updrafts could promote the risk of tornadoes, according to the Storm Prediction Center. Storms are forming ahead of the front across central Virginia and northeast into Maryland, the center's storm outlook says.

The storm center's forecast pits the possibility of tornado activity at 15 percent in parts of Maryland and northern Virginia.

Forecasters at the National Weather Service's office in Sterling, Va., echo warnings of possible isolated tornadoes and severe storms packing damaging winds and heavy rain.

Severe weather blogger Henry Margusity at is predicting a few tornadoes across the mid-Atlantic, winds with gusts up to 70 mph and hail up to 1.5 inches wide. AccuWeather's forecasters are live blogging the storms.

On the bright side, the severe weather is setting up the region for pleasant weather Saturday, as local meteorologist Eric the Red points out, with clear skies and highs in the 70s.
