overnight but at 9:00 still out of the northwest at about 12. temps in the mid-50s. we'll dip into the 40s in d.c. overnight but 30s north and west. you can see some of the clouds up north, too, especially in pennsylvania coming in toward northern maryland, northern d.c. as far as the winds they're gusting over 30 in salisbury. 28 at the pax river -- exexcuse me -- excuse me, leonard town. gusts 25 in hagerstown. yeah, the winds are going to continue for much of the afternoon. temps low 50s north. 62 already fredricksburg. 60 in pax river, also in reedville. easton is 55. here in washington looks nice outside. we've got lots of sunshine, 57 degrees. north west wind at 15 and a dew point is at 31 right now. so it is rather dry. we're looking at a storm system right here in the middle of the country. it's bringing showers and storms to nebraska coming out of colorado. and this thing is going to move east and north. it's going to split into two parts. one part to the northern

plains. the other part is coming here tomorrow afternoon, tomorrow night. so we start with sunny skies for the most part. again, we've got the clouds up to the north but nice afternoon and evening. overnight the clouds start to thicken up, especially toward tomorrow morning. we'll be mostly cloudy through midday. look what happens. this is 11:45. during the afternoon as the showers start to move in here later in the afternoon, could be a few heavy ones by evening to our north and west. if it works out, most of the day, at least through mid afternoon should be dry. today 62, breezy, winds still gusting to 30. 30s and 40s tonight as the clouds increase. showers develop in the afternoon tomorrow, mid- to late afternoon is what i'm thinking now. 58. so if you come out to college park and see me at knight hall in the morning, that will be cool. sunday sun returns, 64. maybe an early cloud or two. monday 70. showers tuesday, in the mid- 70s. then we get hot, 58 wednesday and thursday, chance of an afternoon storm. stick around. we're going to the kitchen french style. 9news now returns in just a
