Yesterday’s Severe Thunderstorm Watch resulted in nary a raindrop for Arlington — but Friday evening might be different.
Another Severe Thunderstorm Watch has been issued for the county, for D.C., and for much of the region. It’s in effect until 11 p.m. tonight.
“[The] main hazards for these storms will be heavy rain, damaging winds and large hail,” the National Weather Service says. “Additionally, isolated instances of flooding rainfall are
possible, mainly in urban areas.”
The scattered storms are expected to arrive locally at or after dinnertime and, like yesterday, could miss Arlington entirely.

Arlington — along with D.C., Alexandria, Fairfax County and other neighboring jurisdictions — is under a Severe Thunderstorm Watch.
Amid temperatures in the mid-90s and several Severe Thunderstorm Warnings to the west, the National Weather Service issued the watch around 1:15 p.m. It is in effect until 9 p.m. and includes much of eastern Pennsylvania and portions of New York State.
Forecasters say that scattered strong storms are likely later today in the immediate D.C. area.
“Scattered to numerous severe storms are possible this afternoon and evening,” the National Weather Service said. “Damaging wind gusts are the primary threat. Isolated instances of considerable wind damage from severe thunderstorms are possible. Isolated instances of large hail are possible as well.”
After the line of storms passes things should quiet down for the rest of the night, but another round of severe weather is expected Friday, forecasters say.

(Updated at 2:15 p.m.) For the second day in a row Arlington is under a Flood Watch.
The National Weather Service says that “anomalous moisture coupled with the potential for multiple slow moving thunderstorms will result in the potential for flash flooding.” The storms are expected to arrive later this afternoon, with the Flood Watch set to expire at 8 p.m.
The flood potential follows storms yesterday (Monday) that prompted Tornado, Severe Thunderstorm and Flash Flood warnings all in the span of about 10 minutes. The heavy rain also flooded a busy intersection along Columbia Pike.
Later Tuesday afternoon a Severe Thunderstorm Watch was issued as well.

More from the National Weather Service:
…SEVERE WEATHER OUTBREAK EXPECTED OVER THE MID-ATLANTIC REGION BETWEEN 2 PM AND 10 PM TODAY, INCLUDING THE GREATER BALTIMORE/WASHINGTON METROPOLITAN AREAS…
An outbreak of severe storms is expected this afternoon and evening across the greater Baltimore/Washington region, with numerous severe thunderstorms expected. There is a significant threat for damaging and locally destructive hurricane-force winds, along with the potential for large hail and tornadoes, even strong tornadoes.
The timing of this outbreak varies with your location. West of the Blue Ridge Mountains, you can expect the storms to arrive between 12 Noon and 3 PM. East of the Blue Ridge Mountains, timing will be from 4 PM to 8 PM. The greater Baltimore/Washington Metropolitan Areas can expect the storms to arrive between 5 PM and 7 PM.
Now is the time to review your severe weather safety procedures for the possibility of dangerous weather today. Do not be outdoors when the storms arrive. When you hear thunder, go indoors to a sturdy building or structure. While seeking shelter indoors, go to the lowest floor to an interior room. Stay away from windows. Those in mobile homes or weaker structures should plan ahead of time to shelter in a stronger shelter. Be prepared for extended power outages, and the potential for some roads to be blocked by fallen trees.
For the after-event cleanup, do not go outside until 30 minutes after you hear the last thunder, otherwise you will be still susceptible to lightning strikes. Be aware of downed power lines and unstable branches and trees.
Stay tuned to NOAA Weather Radio, weather.gov, or other media for watches and warnings. If a Severe Thunderstorm Warning or Tornado Warning is issued for your area, move to a place of safety, ideally in an interior room on the lowest level of a sturdy building.

Monday has the potential for even more active weather.
Arlington, D.C. and other parts of the region are under an “enhanced” risk of severe weather, according to a National Weather Service outlook. Severe winds are likely, according to NWS forecasters, noting the “seriousness” of the threat.

The watch is in effect until 4 a.m. for Arlington, the District and much of the Washington region. Forecasters say flash flooding may occur during prolonged downpours.
More from NWS:

These showers and thunderstorms will be capable of producing heavy rainfall with totals on the order of 1 to 3 inches with locally higher amounts where thunderstorms may train. These totals may result in flash flooding, particularly in urban areas and those that have observed recent heavy rainfall.
Another day, more heavy rain on the way. Be weather aware and stay alert for any warnings issued.
