LIVE BLOG: D.C. Severe Weather Possible

11:27PM: Eileen Whelan Even though the initial threat for severe weather is done before midnight, I think there could be another round to move into the area overnight (between about 3-6AM).{ } The radar image below shows the area of storminess we'll watch overnight, as it tracks East.{ } The big question is whether the storms will hold together.{ } Regardless, they do not look likely to be severe.{ }

9:00PM - Devon Lucie{ } Storms have really slowed up over the Appalachians.{ } Take my earlier D.C. metro times and slow them down by an hour:{ } NW suburbs{ }around 10PM - D.C. about 10:30-11PM - E suburbs around 11:30-midnight.{ } A lack of severe warnings too... good news.

8:45PM: Storms are starting to fire up north of Baltimore and another line of storms is stretching from Hagerstown and Southwest through Martinsburg.{ } These storms will generally track, very slowly, towards the East.{ } The greatest threat will be localized flooding and strong wind gusts.

It's the ABC7 weather department's thinking that our best chance for storms comes after midnight tonight.{ } There is a very slim chance that we might see storms fire up over the next few hours, but we feel that chance is very low.{ } The SPC has discussed the possibility of this storm development too.{ } Here's a glance of the graphic and part of their discussion from about 3pm EDT.{ } To sum up:{ } the risk of storm development is marginal in the D.C. region through the early evening hours.
