Scattered storms on tap for evening hours

August 14, 2012|By Scott Dance

Scattered storms are on tap for Tuesday afternoon and evening, with an outside chance they could become severe.

It isn't especially hot out -- 88 degrees downtown and 86 degrees at BWI Marshall Airport as of 2 p.m. -- but it's plenty humid, with dew points in the upper 60s. With sunny skies, that could help fuel some instability in the atmosphere and cause storms.

The National Weather Service forecast calls for storms to arrive mainly between 5 p.m. and 10 p.m. The storms could possibly bring damaging winds.

The Storm Prediction Center lays out severe storm forecasts that include a 5 percent chance of tornado formation across Central Maryland and the northern Delmarva and a 15 percent chance of severe winds across the entire state. The latest models show tornadoes are looking less likely, but forecasters still called the 5 percent probability "prudent" to maintain.

A tornado warning was issued along the Virginia/West Virginia border north of Harrisonburg, Va., at 2:50 p.m., through 3:15 p.m.

A closer look at an area including parts of Central Maryland and Northern Virginia predicts that a severe thunderstorm watch is unlikely, as of about 2 p.m.

AccuWeather severe weather blogger Henry Margusity includes Maryland in an area that could see intense storms this evening.

Stay tuned for updates if any severe weather watches or warnings are issued.
