onmy: right now, we are storm watch. make sure you keep the umbrella handy. we are tracking potentially severe weather. it could bring strong winds and even some hail. chief meteorologist doug hill is here. doug: looks like it will be later this afternoon, probably between 3:00 and 8:00 tonight. probably closer to 5:00 or 6:00 when we see the best opportunity for showers and storms to bubble up. at reagan national. most other areas in the 70's. we have patches of clouds. still weakening but moving to the southwest of the metro area. later this afternoon, with several more hours of sunshine would help destabilize the atmosphere and the next system approaching, i think we will see scattered showers and storms. the question is where the heaviest ones will be. a few storms could become severe , so a good chunk of the area, not so much south of the metro area, but especially d.c. metro area north and east. as we get through the 6:00 to 7:00 hour, they really blow up and blossom. we go...

hardest. and doug will be backtracking potential storms headed our way.
