5 Things to Know Today: Aug. 19

Good morning, Potomac. We've made it to the end of another work week. Here's your five things to know today.

1. Friday will be mostly cloudy with a 50 percent chance of showers and thunderstorms. Highs will be in the upper 80s. Cloudy conditions will continue into the evening with a 40 percent chance of rain. Temperatures will dip into the upper 60s.

2. On Saturday, Aug. 20, more than 50 members of Montgomery County Fire and Rescue Service, including Fire Chief Richie Bowers, will climb 110 stories at the North Bethesda Market East Tower in honor of their colleagues (343) who died in the 9/11 terrorist attack on the World Trade Center. Organized by firefighter TJ Monahan of Station 33 in Potomac, the event commemorates the 10th anniversary of 9/11. The event begins at 9 a.m. Come on out to support your local firefighters.

3. One-day deal at Whole Foods Market: organic cantaloupe, 2 for $3, (regularly priced at $3.99 each). Sweet melon—yum! This deal is just for today.

4. Ah, it's been a long week for me. How about for you? Consider having a refreshing spritzer, cocktail or brew at one of the local watering holes. , The Irish Inn, , and all offer Happy Hour specials. Oh, and show this twitpic and enjoy a FREE Dim Sum or Street Fare item with any food purchase from 3-6 p.m. at P.F. Chang's at White Flint Mall in North Bethesda.

5. On this day in 1964, the Beatles kicked off their first U.S. tour at San Francisco's Cow Palace. More than 17,000 screaming fans (I'm thinking mostly adolescent girls) let loose when the boys launched into "Twist And Shout." If I had been there, I would have been hysterical. What's your favorite Beatles tune?

Have a wonderful weekend!
