Trenice hi, alison. This afternoon we have a couple of issues and certainly heavy delays starting early this afternoon. First, i of the afternoon first issue of the afternoon 270 corridor, there is a problem in the local lanes before falls road. I ties you up making your way from rockville away from the spur. A half an hour ago we had one reported southbound 270 at the split for the beltway. That is adding extra volume for folks trying to make it to the legion bridge. Live pictures and you can see northbound 270 at a snails pace to make the trip home through rockville. Elsewhere, we will make it to the beltway as you approach the legion here, the outer loop left side. We had report of an earlier crash beyond the camera view. It looks like its gone. But the delays take you from the split at 270 all the way to annandale. We had a work crew that was late cleaning up some stuff in the roadway. They blocked the left center lane for a while. Express lanes are open but the outer lane through lanes are heavy again. There are no reports of new issue through district. We had an earlier crash withoutbound on the southeast southwest freeway after the third street tunnel and that is out to the right of the roadway. The travel lanes will reopen soon as i did see a call for a tow truck to the area. Michelle . Michelle thank you. A warning from Prince William county police to residents. Watch out for bears.

Some late season stretches of cold are taking a toll on the flowers as we know by now so lets check in with ryan hughes who is live at the tidal basin. We were all watching and waiting to see what last nights chill would do. How are they faring . Ryan a little bit of good news and a little bit of bad news. Start with the good news. The National Park service telling us there is no damage from the Cherry Blossoms from last night and this mornings cold but the bad news, a little bit of a different look. They are calling it marble effect. You can see some branches have White Flowers almost near peak bloom. Then look here at another branch branch. You can see the blossoms there dead and brown. That is from the cold snap last week where we are told 50 of the Cherry Blossoms will not bloom this year. It will be less dense and co but there is a little bit of progress. We have now moved in the puffy white stage. The blossoms are expected to peak come this weekend. The National Park service telling us it will still be a great sight to see and the weather is expected to be fantastic. For more on that, lets head inside the to stormwatch7s chief meteorologist doug hill. The weather is expected to be great. Doug it will feel like spring around here. But we start with a look at the low temperatures this morning. These were the air temperatures. 19 in martinsburg and winchester. In washington only 30. That is what saved the blossoms. Had we had these temperatures the tidal basin, the losses would have been profound but we are looking good and the weekend weather will cooperate. If you are thinking of seeing the blossoms saturday and early sunday is the best bet. Rain is likely getting through sunday afternoon. Through the evening we hang on 45 degrees abnormally cold weather continues but not for long. We will drop to 40 degrees. 9 00 tonight, light winds. In the morning instead of temperatures in the upper teens the western zones are in the 30s. A couple of spots could be close to briefly or below the 32 mark. But low in the city is around 34. Around freezing briefly sunrise and a quick rise of temperatures through the day as a warm front moves in the area. The temperatures in the afternoon holding through the mid40s. Dropping tonight. As we get through the overnight we get 30s. Then it changes in the morning. Clouds roll in ahead of a warm front. We will see clearing and the temperatures in the lower 60s as the winds go to the south. When we get to friday afternoon it will be delightful. Saturday is better. Extended outlook shows rain developing. Storm system could bring it sunday night. Monday a chance of showers so mild weather as we go back to the 70degree mark for monday and tuesday. Then we turn cooler. Look at the numbers. Daytime temperatures in the low to mid60s. Most importantly as we get through tomorrow, look at the lows tonight. Only the mid40s. Maybe spring is here. Michelle hopefully no more extreme turns again. Doug i hope not. Please no. I think we are done with it. Alison thank you, doug.
