middle of the street. >> the day was gray. the mood was somber. protesters gathered here in freedom plaza, calling for justice in the killing of an unarmed black teenager in it florida. good evening, i'm chris gordon. they wore hoodies in honor of trayvon martin. he was wearing one when he was killed by a neighborhood watch volunteer. that man, george zimmerman, claimed self defense and has not

when he wasn't. law professor lisa cruise robinson says for her and her son, there has been a dialogue. >> he said, i have rights. and i said yes, you do have rights. but it's about diffusing the situation so you can assert your rights later rather than assert your rights at the onset and run the risk of being murdered. >> whatever your race, whatever your religion, this is just a tragedy. and i wanted my children to see it, and my wife wanted our children to see it. because today it's trayvon. tomorrow it could be any of us. >> reporter: and then the haunting poem told from the perspective

live from northwest washington, darcy spencer, news4. >> thank you, darcy. yesterday we had a preview of summer and today spring arrives. >> no kidding. up and down we go. 83 yesterday with the sunshine. today nowhere near 83 degrees with all of the clouds and the drizzle and the rain out there. it's been kind of a dreary looking saturday afternoon. so the big question is, can we make it any nicer on your sunday? kinda sorta. let's look outside now on your saturday afternoon, turning into a saturday evening, cloudy and drizzly and damp and kind of not the best-looking day to be outside today. hasn't rained all that hard, but it sure has been enough to get you wet and make you mad. 58 right now here in washington with an east breeze at 13 miles per hour. that easterly wind is a big part of the forecast here over the next 24 to 36 hours. we have been stuck with that onshore easterly wind. 50s and low 60s. just out to the west and south, the sunshine was out almost all afternoon, south of winchester, it's 71 in charlottesville right now, and 70 in fredericksburg. generally speaking, hovering in the low 60s through your saturday evening with off and on chances for showers and maybe some rumbles of thunder after 9:00, 10:00, 11:00 this evening. on the radar, nothing around here. flash flood watches out for harrssonburg and stanton and charlottesville, auto part of a larger more dynamic weather system. severe thunderstorm watch until 10:00, just south of la ray, really from harrssonburg through the southern end of the shenandoah and roanoke valleys. and big severe weather down just to the east of roanoke. a big thunderstorm going just to the south sides of lynchburg, generating 2 to 3-inch diameter hail. so big down to our southwest. we're stuck around here with the drizzle. but the timing on this is going to ride these showers and thunderstorms up to the neck of the schehenandoah valley over t next two or three hours and then might get a couple rumbles in here late this evening. for your evening, cloudy, mild, stronger thunderstorms in the shenandoah valley, not much of a severe threat in washington, thanks to the cool, marine layer we have outside. then tomorrow, mostly cloudy, scattered showers, one or two rumbles tomorrow. but a 71-degree day in march. we can't complain too much about that. it will not be a washout, but there will be off and on rain chances through tomorrow. breezy and sunny and we'll call it chilly. t first time in more than two weeks coming our way on tuesday. >> now, chuck, you haven't seen this, so i'm going to invite you to look along with our viewers. here is our very own storm 4 chief meteorologist doug kammerer making that lay-up. he took on the harlem globetrotters today at the verizon center. doug misses this
