June 13 D.C. storm timeline: Most severe storms likely during afternoon

A small line of storms rolled through the Mid-Atlantic and onto the Eastern Shore Thursday morning, causing little disruption save a few downed trees.

The severe threat still exists into the afternoon though, as the National Weather Service plans to issue another Severe Thunderstorm Watch for the D.C. area soon.

A high level of uncertainty still exists about just how strong Thursday afternoon's storms will be based on the conditions that continue to develop over Washington.

Chief Meteorologist Doug Hill says that the severity of afternoon storms depends on how much sunshine and warming the region gets in between storms.

He says that the longer the sun shines, the more unstable the atmosphere will become. That makes conditions more conducive for severe weather.

Temperatures in the region continue to rise into the low-to-mid 80s. An air mass with strong storms is pushing its way out of southern Ohio and into West Virginia. It's yet to be seen how strong those storms will become and if they'll hold together as they crawl across Blue Ridge.

However, the very latest severe weather outlook from the National Weather Service shifts the "moderate" risk for severe weather south of the D.C. area, leaving Washington at a slight risk.

It should be noted that the latest outlooks do not make any mention of the development of a derecho. On Wednesday, ABC7 meteorologist Jacqui Jeras said that the development of a derecho in the D.C. area was rather unlikely.

The bottom line - keep your eye on the sky and on ABC 7, NewsChannel 8 and
