2 p.m. — Severe thunderstorm watch issued until 9 p.m.

Due to the potential for intense storms into this night, the National Weather Service has issued a severe thunderstorm watch for all the D.C. area and over a area that spans from Richmond to Philadelphia.

“Damaging winds are likely to be the most common hazard with some hail possible as well,” the Weather Service’s Storm Prediction Center writes.

Remember {that a} severe thunderstorm watch means substances are in place for doable severe storms; they don’t seem to be a assure. However, if a severe thunderstorm warning is issued in your location, it means a severe storm is imminent and it is best to search shelter.

Original submit from 1:30 p.m.

Six days after intense thunderstorms erupted in the Washington area, together with two tornadoes, one other spherical is predicted this afternoon and night. Today’s storms may be fairly vigorous, with the potential to provide damaging gusts and hail in addition to heavy downpours and frequent lightning.

The twister threat is decrease in comparison with final Friday, however we can’t completely rule out a short-lived tornado.

The storms are being fueled by sizzling, humid air forward of a robust chilly entrance advancing towards the area. Today will most likely be the third day in a row topping 90 levels earlier than the storms expel the warmth, making means for an exquisite stretch of climate Friday via the weekend.

D.C.-area forecast: Strong storms late at present convey warmth reduction by Friday

The National Weather Service Storm Prediction Center has positioned the area in a degree 2 out of 5 threat zone for severe storms, which stretches from round Virginia Beach to Philadelphia.

Timing: Storms ought to provoke, largely west of Interstate 95, between 2 and 4 p.m. Storms will most likely be most quite a few between 4 and eight p.m., however might linger in some areas — particularly south and east of Washington — via round 11 p.m. Rain needs to be over in most areas by round midnight or so.

Small probability of: Violent winds (over 70 mph), giant hail, twister

Rainfall potential: Averaging round 0.5 inches, however localized totals over 2 inches doable.

The setup at present contains a risky mixture of an unstable air mass, plentiful moisture, growing winds with altitude, or shear, and a number of other mechanisms to elevate the air. The climate map for two p.m. is proven under.

On this map, you’ll word an approaching chilly entrance with a weak low stress system. Ahead of this entrance, in the soupy air is one other area of low stress. These two programs are anticipated to create appreciable low-level convergence of air inflicting it to rise and gasoline widespread thunderstorms via the afternoon and night.

Storms might set off as early as 2 p.m., particularly in our western areas, and regenerate in the area over the next 5 to six hours.

The essential type of group recommended by the fashions is a multicellular mode — the place bigger, intense clusters develop, with some evolving into brief arcs or strains.

Given the strengthening wind shear anticipated via the afternoon, a number of cells might briefly purchase rotation, which will increase the potential of some bigger hail and maybe an remoted, weak twister.

Severe thunderstorms warnings will most likely be issued for damaging wind gusts in the 50 to 70 mph vary. Lightning could also be significantly intense in spots. Additionally, these cells will unload heavy downpours, and repeat passage might end result in localized totals exceeding 2 inches in a short while.

The Weather Service’s Weather Prediction Center has positioned the area in a marginal threat zone for extreme rainfall that might trigger flooding — primarily close to streams and areas with poor drainage.
