storm warning in the klein nays and in the southern plains it's tornadoes. 63 twisters reported so far this week. this is what it looked like from inside a storm shelter north of oklahoma city. ferocious winds catapulting debris all over a farm. tonight, round three with storms pummeling texas, east of lubbock. adriana diaz is in north texas. >> all right. this one means business. >> reporter: all week, this has been the scene-- funnel clouds filling the sky, high winds and heavy rains have spawned multiple tornadoes throughout the night. authorities say flash floods wiped out the train tracks derailing 17 cars of this freight train in valley view texas. >> oh, my god, a fire. >> reporter: a lightning strike caused this gas well to ignite and burn for hours near denton texas. mark fox with the national weather service says the damage was nowhere near what happened

in bridge creek, oklahoma on wednesday. >> definitely dodged a bullet. if this had come over a little bit more populated area, it could have been a lot more. >> reporter: just north of oklahoma city, this cell phone video captured the powerful winds whipping debris right outside a storm shelter. flash flooding remains an urgent threat. as much as four-and-a-half- inches of rain has fallen in some places over the last two days, causing rivers to overflow and damaging this era, texas elementary school, forcing it to close. carl kanplin and his son, kevin, lost their cattle in an eight- foot flood surge from a nearby creek. they're now on a rescue mission to find their livelihood. >> you hate to lose one even and when they're not worth much and when they are worth a lot, you really hate to lose one. >> reporter: the government has put state emergency responders on alert because, scott, as we head into the weekend, the worst may be yet to come. >> reporter: larry mowry is chief meteorologist at k.t.v.t

our cbs station in dallas-fort worth. larry, what's in the forecast? >> scott, a large part of texas and oklahoma remain under a tornado watch this evening. that's where the greatest threat of severe will be through the evening hours. tomorrow, this exact same location with the threat of severe weather, two-inch hail, winds to 70 miles per hour. and a high tornado threat again tomorrow across the central and southern plains, and on mother's day, the slight risk continues. a slightly lower threat for severe weather but a higher flooding threat across this entire area. >> pelley: and tell us about the severe weather in the atlantic. >> yeah, we have subtropical storm anna right now. you can see tropical storm warnings in effect from north carolina all the way to charleston. this storm will slowly move towards the coast as we go into the weekend, spread thing heavy rain and the threat for some high wind as we heads into saturday night and sunday morning. i expect landstall on sunday morning with myrtle beach to wilmington with gusts as high as

55 miles per hour. >> pelley: larry mowry at k.t.v.t, larry, thanks very much. then there was the snow in california. it was a dusting in the mountains about an hour east of los angeles, but still enough for one school district to cancel classes. it wasn't the weather today that sent a single engine plane careening on to a busy interstate in atlanta. all four people on board were killed. they were on their way to a family celebration. here's mark strassmann. >> reporter: this cell phone video shows the highway fireball moments after impact. the pilot had radioed the tower right after takeoff he was having trouble climbing. then he said, "going down." motorists saw a plane 25 feet in the air and struggling. it burst into flames when it struck the median. >> as i turned to get on the 285, boom! impact. >> shook up. >> reporter: gerald smith saw the plane head right for the semi he was driving. >> it was like it was coming

directly at my windshield. i slammed on my brakes and by that time the plane came directly across my hood. >> reporter: it grazed his truck moments before crashing. >> made my way out seeking help. and by the time i got over there, it was blazed up so bad there wasn't nothing nobody could do. >> reporter: the plane was a piper pa 32 like this one which seats six. four people, greg byrd, his sons christopher, and phillip, and jackie kulzer, a fianceé, were headed to ole miss to see another son's graduation tomorrow. fire captain eric jackson: >> right now f.a.a. and representatives of n.t.s.b. are here on the scene. they are taking a look at the scene, taking a look at all the parts and everything that went into just how this plane crashed. >> reporter: that charred highway median behind me is where the plane crashed. the cause is still unclear. dekalb-peachtree airport flies in a congested residential commercial area and for a pilot taking off, scott, the highway is one of the only options.

>> pelley: mark strassmann in atlanta for us tonight, thank you very much.ma one of the most notorious missing children's cases remains unresolved. today, a judge in new york city declared a mistrial when jurors deadlocked in the trial of pedro hernandez, charged with murdering six-year-old etan patz in 1979. hernandez confessed 35 years later, but there were doubts about his mental health, and one juror refused to convict. it was after patz that missing children began to appear on milk cartons. today, the pentagon increased security at military bases throughout the nation reflecting an increased concern over terrorism. we asked homeland security correspondent jeff pegues to look into this. >> reporter: isis propaganda has increasingly focused on attacking u.s. soldiers. the bulletin sent to military installation called fair heightened awareness but did not

mention a specific target or plot. since sunday's failed attack in garland, texas, there has been a flurry of bulletins from federal agencies sent to law enforcement offices around the country. one says isis' messaging is resonating with u.s.-based violent extremists. another says homegrown violent extremists may elude attention and attack with little or no warning. that's what happened at the prophet mohammed cartoon contest in garland. the f.b.i. told the police that elton simpson might be interested in the event, but bureau did not know simpson and his accomplice nadir soofi were planning an attack. f.b.i director james comey says there could be thousands of people in the u.s. following isis propaganda online. the f.b.i. prioritizes which to monitor most closely. today, comey held a conference call with representatives from about 500 police departments urging them to share

information. ron hosko is a former assistant director of the f.b.i. does the f.b.i. have the resources to keep up with these threats? >> no. the f.b.i. is evolving, but the speed of change and opportunity has been one that's been difficult for law enforcement and the intelligence community to keep pace with. >> reporter: the growing threat means there could be more surveillance of potential suspects. scott, today, director comey asked state and local officials to take another look at closed investigations, as well as cases that had been categorized as low priority. >> pelley: jeff pegues in the washington newsroom tonight. jeff, thank you. there was an amazing sight in new york city today. thousands of police officers lined up 10 and 20 deep to salute officer brian moore, shot last saturday in the line of duty. bus loads of cops came from across the country-- california,ou louisiana, illinois-- too many to count.

25-year-old officer moore was investigating a man with a gun when he was shot in the head. a suspect is in custody. as often in the n.y.p.d. moore's father was a cop. his uncle was a cop, and three cousins, too. moore took the police entrance exam at the age of 17, and in his five short years, he won four service medals. today u.s. attorney general loretta lynch began an investigation of the practices of the baltimore p.d. six officers were charged last week in the death of freddie gray whose neck was broken while in custody. chip reid has been looking into what it means to live in gray's neighborhood. >> in sandtown a violent poverty stricken baltimore neighborhood where freddie gray lived, members to have the charitable group centers for urban families walked the streets this week trying to help people find work.

>> a job training program up in monroe. >> reporter: despite monumental challenges, joe jones, the center's founder and c.e.o., is determined to turn this neighborhood around. >> 50% of african american males between 20 and 30 are unemployed. you can't have that number of people out of the labor market and expect that a community is going to thrive. >> reporter: over the years, there have been many efforts to save sandtown. in the early 1990s, former president jimmy carter and presidential candidate bill clinton came here when developers and the city were pouring $130 million into urban renewal. the project largely failed because jobs did not materialize. about 50% of sandtown households earn less than $25,000 a year. only 6% of adults have college degrees. only about half of eighth graders can read proficiently. one of the biggest problems here is that with so few jobs available, selling drugs on the

street has become a rite of passage for many young men. can i ask you how many of you have a criminal record? >> i do. >> all of us just about. >> all of us. >> if you keep living in sandtown, you're going to hustle. >> reporter: "hustle" meaning sell drugs. >> absolutely. >> it's not that you're looking at what they're doing as illegal. it's what you see as, okay, this person is making money. they-- they're feeding their family. >> reporter: but every member of this group is employed. they've overcome their pasts. now their mission is to convince others that they, too, can pull themselves up, even in sandtown. chip reid, cbs news, baltimore. >> pelley: turns out black unemployment has dropped in april, below double digits, for the first time in seven years. today's jobs report shows the economy began to thaw from the dismal winter. 223,000 jobs were added. unemployment dropped to 5.4%. that's also the lowest in seven years. black unemployment was 9.6%.

but paychecks still aren't growing. pollsters and pundits in the u.k. may be out of work after blowing the call on yesterday's election. they predicted a dead heat, but the conservative prime minister, david cameron, scored a decisive victory. mark phillips on the british election that had a surprisingly american feel. >> reporter: david cameron came back to number 10 downing street today as the leader of a majority government, a small majority but one just big enough to govern. and for the defeated party leaders, there was a political bloodbath. >> i'm so sorry. >> reporter: ed miliband, labour leader, resigned. >> i will be resigning. >> reporter: nick clegg, deputy prime minister, resigned. nigel farage of the right wing u.k. independence party, resigned. >> i'm not saying i am standing down. >> reporter: only the scottish nationalists who wiped labour out in scotland also came out big winners. >> having a go, that pumps me

up. >> reporter: david cameron's victory came after a campaign that had an undercurrent of nastiness. when the labour leader broke political rule one by awkwardly eating a bacon sandwich on camera, the tory press was ruthless. "miliband didn't look like a prime minister," they said, "now he won't be." this despite labor bringing in obama election guru david axelrod as a consultant. both sides used american political pros. another obama aide, jim messina, helped mastermind the conservative win. for u.s. republican pollster and cbs news consultant frank luntz, this was an election with a familiar feel. >> there's no commonality within the parties. there's no civility. there's no respect. and that makes the elections particularly negative, particularly divisive, and you've now got an electorate that is just plain cynical. >> reporter: and, scott, there's fallout from this vote. the strong showing by the scottish nationalists may lead to calls for another referendum, soon, on scottish independence.

the uncertainty isn't over yet. >> pelley: mark phillips outside the houses of parliament for us tonight. mark, thanks. some claim we have been hit by a pollen tsunami. well, it's certainly nothing to sneeze at. and they flew today on the wings of history when the cbs evening news continues. the #1 prescribed acid blocking brand. available without a prescription for frequent heartburn. get complete protection. nexium level protectiontm. ♪ to you, they're more than just a pet. so protect them... ...with k9 advantix® ii. it's broad-spectrum protection k ills fleas ticks and mosquitoes too. k9 advantix® ii. for the love of dog™. people with type 2 diabetes come from all walks of life. if you have high blood sugar ask your doctor about farxiga. it's a different kind of medicine that works

perfect storm of misery. here's dr. jon lapook. >> reporter: just when everyone was done suffering through an awful winter, the late arrival of spring has brought a new misery. its named etched in, well, pollen. addriana gutierrez suffers from allergies every spring, but today was so bad, she called in sick and went to the doctor for a skin test. >> okay. not too bad. >> as you see i'm very stuffy and my eyes and skin are developing all these rashes right now. >> so trees are the main allergen for you. >> reporter: allergist cascya charlot said it has been an especially bad week. >> we are seeing patients with allergies previously but never had such severe allergy symptoms as they are experiencing now and we are also seeing patients who are developing allergies for the very first time. >> reporter: across the northeast and parts of the midwest, tree pollen levels have been very high. some of the worst cities include burlington, vermont, buffalo

new york, and cleveland, ohio. guy robinson is a certified pollen counter for a national allergy academy and says any level over 90 is elevated. what was the most recent pollen count that you measured? >> the most recent one here was probably just over 2,000. >> reporter: is that high? >> yeah, that's considered very high. anything over 1,500 is very high. >> reporter: one doctor said this year we're going to have a pollen tsunami. now, is this a particularly bad year, or do people just forget how bad it was last year? >> i think, yeah, the latter. people forget the first week in may is usually the worst time of the year for most people who are going to have allergies. >> reporter: one tip for people suffering from a pollen allergy- - when you get home take a shower and be sure to wash your hair. otherwise, invisible pollen can keep sprinkling down. and, scott, don't wait too long to seek help. medications often work best when given before symptoms get too severe.

your realtime captioner is linda marie macdonald. now at 6:00, word of a possible punishment in pro football's "deflate-gate." the nfl may be coming down hard on patriots quarterback and bay area native tom brady. let's get right to joe vazquez on what the league may have in store for the quarterback. >> reporter: i think it's safe to say tom brady is a hero to a lot of folks here in his hometown of san mateo to the entire region of new england, but the nfl apparently is convinced he is a cheater and that he should be punished. super bowl winner tom brady will sit out some games next season. the "new york daily news" says roger goodell will announce the suspension next week.

it comes after an investigation found tom brady, quote, was at least generally aware that the patriots were deflating footballs before a play-off games against the indianapolis colts. how long will the suspension last? csn new england reports the patriots are fearful that the nfl will suspected brady for six to eight games. at salem state yesterday he put on a brave face. >> how are you handling this controversy? is it bothering you? >> i have dealt with a lot of things in the past. i dealt with this before the super bowl, a lot of adversity in my life and i'm fortunate to have so many people who love me and support me.
