lightning with this one too. right around the huntingtown area, route 4, route 2, heads up, 301. you can see the lightning associated with this storm. severe thunderstorm warnings for these areas. mt. vernon, look at all the lightning now. we may see this warning push up into d.c. south fairfax county, wood bridge, and across the river to southern prince george's county. to the west, this one has weakened a little bit. south of front royal, heavy rain here. more rain around martinsburg and winchester. and this one around leesburg, let's zoom in, just to the south of frederick. coming into frederick now, along 340. if you're in buckies town, get ready. you have a big thunder boomer making its way. amelia, this is not a huge severe weather event, but we are going to see some severe impacts. >> and i think t

doug was just showing you rain closing in on 270. there you see the dark skies. still dry roads there, but they're going to be wet rather quickly. look at the severe weather impacts. flash flooding, heavy rain the biggest concern. next would be strong, gusty, damaging winds, potentially hail as well. and we're thinking the severe weather will wind down by about 8:00 p.m. tonight. >> and we're watching this area of low pressure, this upper level low, spinning back to the west. this is where the moisture is. there's another spin on top of us and that's why we have the severe weather. this moves out tonight. tomorrow, 77 degrees, peeks of sun, a little bit of on the windy side. winds 20 to 30 miles an hour. a stray shower could be possible too. the next ten days, 80 degrees on saturday. a good chance of scattered showers and storms. possibly severe.

sthm and we just talked about this storm, it may be warned. and we have that now. along i-95, eastern fairfax county, arlington county and the district until 6:15. you can see this line of storms continuing to develop now. more storms up to frederick and another one that's developed west of dulles. but here's the new warning. it's a small warning, but notice how much of the area is in a warning. one here, in this area and another all over southern maryland. so it looks like one big warning. severe thunderstorm warnings in effect

doug. >> speak with shane, please. i'm sick and tired of you guys! get the hell out of here! get the hell out of here! >> you heard it first last night at 11:00. now at 5:30, a congressional candidate charged with assault, accused of body-slamming a reporter right before a special election. that candidate, greg gianforte is running to fill the seat vacated by the current interior secretary. joining us now with a look at the possible impact and more on today's political headlines, nbc's senior political editor, mark murray. let's start in montana where that special election is under way today. gianforte hasn't apologized, but with a lot of ballots already cast will this impact the results, or if he wins, could we see a backlash? >> we just don't know, jim.

but never something like this on the eve of an election, where a political candidate is cited or charged for misdemeanor assault right before the election. two-thirds of the vote is already in, absentee. so a lot of people from montana have already made up their minds in this contest. but that said, the one-third who are the day-of voters, which are more persuadable. if you're an early voters, you're probably a strong partisan voters. so the persuadable people could tip the balance, but we're not going to find out until late tonight whether the incident last night impacted the race. >> two-thirds is a lot already cast. that video has gone viral today from europe. president trump appearing to shove past the prime minister of montenegro, this on top of his chastising of nato allies.

the white house on that particular video, but what i will end up saying is that the festivities and a lot of the pomp and circumstance that you saw from saudi arabia in the middle east was probably the cumbaya moment of the trip. and this one was a lot more testy, with some of america's biggest allies, including france and germany. so it was pretty stunning to see the images and really the contrast between president trump and saudi arabia earlier on his trip and then today with some of the european leaders. >> already, from a body slam to a push past, mark murray, thank you. we invite you to stay tuned after news4 at 6:00. we have a complete wrap-up of the president's overseas trip and events back here at home. that's all ahead on "nightly news" with lester holt. this is a great story. a fire in bowie gutted the home
