temperatures have cooled nicely down to 72 degrees. winds are now calm. temperatures around most of the region are in the low to mid-60s. so it is really another cool one. and it will be quite cool when you wake up in the morning. storm team radar is all clear right now. but you really do not have to go too far to the west to see where the showers are right now. back into portions of as close as western portions of west virginia, kentucky, ohio, and even some storms down to the south that are moving up along the front. so some of the latest computer models now bringing this in a little earlier. here is 8:00 a.m. this is our latest computer model. our in-house model, our storm team future weather talking about showers, maybe as early as 8:00. they could even be back down towards culpeper towards 7:00, 8:00. 11:00, maybe a little bit of a break as the rain moves in. and then we start to see some heavier storms move through. look at the line of storms developing around 1:00, 2:00. how about 3:00 right on top of d.c. if you've got a game around 2:00, 3:00 in the afternoon, i

think that's going to be the problem area during the day. and we said earlier this afternoon, it could be between noon and 4:00, the biggest problems during the afternoon. by 5:00, this is all out of here. and we may see an isolated shower or two after that. it's really the noon to 4:00 period that we could see very heavy rainfall. behind this, well we get a lot cooler. but first, what about the severe risk. are these going to be really strong? no, i don't think so. high winds, heavy rain. but nothing on the high side for sure. i'm really not expecting much in the way of severe weather. high temperatures 80 degrees ahead of the storms. 73, though, back towards winchester. only 68 in petersburg. temperatures will fall quickly once the rain starts. so these numbers will be going down by the end of the day tomorrow. expect much cooler conditions on sunday. high temperature of 76. temperatures on monday around 78. that's a beautiful day with plenty of sunshine. but look at monday morning. monday morning is going to be a cool morning. 57 in the city. 51 in martinsburg. 49 in hagerstown. 54 in leesburg.

the kid will need the jackets as they head out to school on monday morning. same deal on tuesday. this is the nice fall weather we like. cool nights and very warm days. that's exactly what we're going to see all week long. look at all of that sunshine too. i don't mean to speak for everybody when i say this is the kind of fall weather we like, cool nights and very warm days. not everybody enjoys it. >> who doesn't like that? >> there is a guy mid name kid. find it. a crazy game in charm city tonight. khris davis and an angry bird against the royals. dave is up next. st

this is the xfinity sports desk, brought to you by xfinity. your home for the most live sports. >> dave started us off saying 7 1/2. you have better news for us. we're eight games. >> wait. i keep -- >> 8 1/2. >> 8 1/2. >> i keep getting the patriots radio broadcast somehow in my ear. the folks in audio, i'm just stalling basically right now. it's friday. but it probably feels like a month of mondays for the nationals. a three-game series with the mets left the nats seeing red and feeling blue. but we know there is no crying in baseball. only games to play. season might feel like it's over. but the schedule has the nationals in miami tonight to start a three-game series. about 67 fans. one of our staff meetings there at marlins park in miami. miami native gio gonzalez, all his family and friends on the mound. bottom of the fourth, a man on. gets him swinging to end the i think. only gave up one run allowed.

four strikeouts in 5 1/3. that's great. top 7, two on, two out for bryce harper. bryce goes down swinging. he struck out three times and stranded four runners. and not just bryce harperling. the last chance for the nats with a man on. nats lose their fourth straight, 2-1 the final. all right. brace yourselves for this one. one of the wildest games we've seen. orioles hosted royals. bottom of the 8th, bases loaded. swinging for the fences. the foul pole, whatever you want to indicate, it goes off the top of it. grand slam. the orioles take an 8-6 lead. now later in the inning, franklin morales facing khris davis. morales, that's not a strike. crush is not happy about it. crushes the bass. he is also upset about serena losing he gets tossed. the picture should have gotten tossed. but the birds have the bucks'

back. bases loaded. >> another one? >> another one. two grand slams in the eighth inning. the eighth time this has ever happened in the same inning. the orioles won a wild one, 14-8. at the u.s. open, serena williams confident in her quest for the grand slam. but unseed roberto vinci unbelievable. watch these players all over the place. vinci, it's finally able to put it away. and then you have to check out her reaction. yeah, she is feeling it. firing up the crowd. she would break serena in that game. match point, vinci, the 43rd ranked player in the world on the verge of a stung upset. she is able to finish it off with a drop shot. ending serena's chance with a grand slam and snapping her 33-match win streak in majors. all right. high school football battling seneca valley battling northwest. just a couple of miles from each other. darius golston. 32 yards for the score and a 14-0 seneca lead.

end of the quarter, quarterback they call markey mark. some good vibrations here. valley still leads, 14-7. that was a good hit. late in the third, pierce's pass batted down by seneca valle. head coach fred kim part of the celebration whether he likes it or not. >> we told them, hey, you got to weather the storm. if they're going to make plays, they're a good football team. >> way to go! >> that's really 1990s by the way. >> smack!
