The National Weather Service Monday night issued a Flash Flood Watch for Northern Virginia beginning Tuesday evening into late Wednesday night. 

The area is expected to get battered with rain nearly all week, continuing into Thursday. There is a potential for flooding starting late Tuesday and conditions could be setting up for a tornado threat Wednesday, said Carl Barnes, meteorologist with the National Weather Service's office in Sterling.

The area could see up to 5 inches of rain fall from Monday to Thursday.

Timeline:
  • Monday afternoon: Light showers; high near 64 degrees
  • Monday night: 90 percent chance of rain
  • Tuesday: 100 percent chance of rain; 1/2 inch of rain expected; high of 57 degrees; gusts up to 25 mph; high near 57 degrees
  • Tuesday night: 1-2 inches of rain
  • Wednesday: 100 percent chance of rain; high near 68 degrees. Stormy weather after 12 noon
  • Wednesday night: Showers, thunderstorm
  • Thursday: 40 percent chance of showers; high of 76 degrees

One-two punch Tuesday, Wednesday
Expect the worst of the rain Tuesday night into Wednesday; and Wednesday during the day and into the evening will be prime time for thunderstorms and possible tornado weather, Barnes said.

"We're looking at probably starting out with light rain today [Monday], for the metro area, about 2 p.m.," he said. Going into Tuesday, the rain will be "moderate" with periods of heavy rain. "There are some concerns for flooding mid-week," Barnes said. 

The heaviest rain will likely fall Tuesday night, through pretty much all day Wednesday, with Wednesday afternoon seeing a threat for thunderstorms, Barnes said. Some of those thunderstorms may be severe; the area could see damaging wind gusts both Tuesday and Wednesday. 

"There is a possibility" for tornado weather on Wednesday, he said. "The best chances for any tornado formation would be Wednesday afternoon going into Wednesday night; depends on how [the thunderstorms] swarm up and get organized."
