we saw them over nats park once again for the third day in a row. down by the airport, though, not a whole lot of rain reported. you can see the airport right now is on the dry side. here's the radar over the last six hours. you notice clear right now, but here's where the showers were, and again, some very heavy downpours coming through the rockville area, down mcclain, down through southeast washington. annandale seeing some of that heavy rain. and we are dry across the area and start to go dry out just a little bit. we need to see the rain. out to the west, you may see some fog as a result of that rain when you wake up tomorrow morning. the high today, 86 degrees. average high for today. i think we have great weather ahead. most of us stay on the dry side. can't rule out a few isolated showers, and any showers that do develop could create some heavy downpours again. winds, they're on the calm side. we have seen some nice, cool

evenings, nice, cool morpnings, and that's what we'll deal with tonight. coming in at culpepper at 74 degrees. we had some cloud cover come across, and with all the sunshine today, we saw some showers and thunderstorms back toward the mountains. they did cross our region. now we're looking for a few clouds coming on through. slight chance for a shower tomorrow, but right now all eyes are on tropical storm isaac. it looks like it's really trying to get its act together, though the latest aircraft that just came out of there still finds winds of about 45 miles an hour, the center kind of tough to find right now. moving west at 20 miles an hour. i think this will stay a little farther to the south and that could mean a couple things. first off, for puerto rico just some rain and wind. not a huge deal but they could deal with some flooding. then it's going to come across hispanola, and if it interacts with these mountains, these are 10,000-feet peaks here. i do expect this to become a

hurricane, and it could increase a little bit more beforet moves across cuba and potential sb potentially into western florida or even the gulf. a lot of concern for the tampa region. this could be a little farther to the east and maybe a little stronger of a storm. we're going to watch the official forecast from the hurricane center bringing it close to tampa by monday. as far as our forecast is concerned, looking good. mostly clear. nice conditions. cool in the suburbs, down to about 56. again, watch out for some of that fog. 88 on friday, 88 on saturday, 88 on sunday. can't rule out the chance of a shower on saturday, but then nice weather continuing. highs in the upper 80s just about each day. no real hot weather. we have a couple cool nights out there, and as we mentioned yesterday, one of the nicest stretches we've seen in a while. >> it's nice. uh-huh. uh-huh. >> we've got sports coming up.

. we were hoping we'd be doing some sweeping tonight, but unfortunately that is not the case. the nationals did not do it tonight, though. they took on the braves, tried to make that sweep. eight games in the division. it seemed like highly probable that the nationals would get this done, but there is a reason they actually play the game. nice moment before the game as the nationals honored chipper jones in a ceremony. he is retiring after 19 seasons. very cool to be in the hall of fame. we begin at top of the 5th, prada hits the pitch and finds the gap over the head of brice harper. two runs in to score.

the braves would go up 2-0, and it would stay that way for a while. this is michael northrup. he fires out in left field. that was morris' first hit in the series. two on for ian desmond, but oh, no, it's right into the double play. a missed opportunity. the nationals had several of those tonight. they fall to the braves. . 5-1 is the final. the rangers took it to texas but the rapingers had a different idea. mitch morlin is going to touch them all. the rangers go up8-1. belltry already has two home runs for the night. can i have another? three home runs for beltry, two of them this inning. 12-3 the final over the o's.

the guy who wears that number now, quarterback josh wilson, he used a retirement party as a way to make some money. very clinton-esque. >> i heard that, and i was saying if he wants to buy his jersey back, his number is available if he wanted to buy that. he made a lot of money here, so i know he still has a lot. this is my second year. but you know, c.p., if you're listening, talk to me, man. >> you won the sacrifice. >> i won the sacrifice. i wear 25, 24 for a day if that's what it takes. >> i think clinton can >> i think clinton can appreciate a good
