Note that snow this week may affect some events this weekend, particularly music and entertainment, special events and even restaurant hours. Call ahead or check Twitter before you go. 

Friday: Nevermind that it's Valentine's Day. Or that there's snow on the ground. Kanye West brings his Yeezus Tour to Baltimore, news for those of us who foolishly passed up the November show at Verizon Center, which pop music critic Chris Richards described alternately as "Stanley Kubrick shooting a porno on Broadway," and "a pro athlete relishing the Jumbotron replay." Tickets are still on sale at $46.50-$126.50.

Friday: Okay, back to Valentine's Day. If you're without a reservation, it's not completely hopeless. A scant few restaurants still have reservations, though with the snow, you just might be able to steal someone else's when they no- show. Here are a few tips to landing a table. And if you're single tonight, or just not feeling it, check out our singles parties and anti-Valentine's events.

Friday:  Bell's Hopslam, one of the year's most anticipated seasonal beers, has arrived in Washington. The Black Squirrel will serve the seasonal, limited-edition double IPA, made with six kinds of hops, during Friday's "Dueling Hops" event, which places Hopslam side by side with another hoppy brew, Troegs Brewing Co.'s Nugget Nectar. They're not exactly the same: Nugget Nectar, while also loved by hopheads, is a malty red ale that packs five kinds of hops without being as boozy as Hopslam. (Nugget Nectar has a 7.5 percent ABV, while Hopslam is 10 percent.) Both beers will go on tap at 5 p.m.

Friday: Rosanne Cash  has had a prolific music career, churning out a handful of chart-toppers and winning a Grammy Award in the 1980s. Last year, however, with the album "The River and the Thread," a rollicking, bluesy meditation on her father's South, the singer has re-emerged as a country powerhouse. If you missed Cash's sold-out residency at the Library of Congress in December with husband and co-songwriter John Leventhal, this weekend's show at Lisner is another chance to see her perform songs from the album. Tickets are $35-$55.

Saturday-Monday: Visitors to the National Portrait Gallery this weekend can get a look at the future, literally. Artist David Datuna’s  interactive sculpture, "A Portrait of America," utilizing Google Glass technology, will offer guests not only  the opportunity to observe the piece — a 12-foot American flag sculpture containing numerous portraits of both historical figures and pop icons — like a conventional art object, but, if they choose, to also engage with it using Google's high-tech specs.

Sunday: A long weekend means one extra day to party;  Town burns the midnight oil with the HOMOlympics. Think: Opening and closing ceremonies and a parade of teams, as well as the games themselves. Banaka, Jaxknife and Stephen Benedicto are among the performers; Aaron Riggins, Ed Bailey and special guest Majr handle DJ duties. Admission is free from 10-11 p.m. and $5 after.

Monday: Following in the footsteps of fellow Odd Future collectivists Tyler, The Creator and Frank Ocean, Earl Sweatshirt seems ready to explode into the hip-hop mainstream. The deep-voiced emcee, a.k.a. Thebe Neruda Kgositsile, is hitting the festival circuit this spring and summer. Catch him first at the 9:30 Club; doors open at 7 p.m.  Tickets are $25.

Through Monday: It's perfect timing for all the young fans watching figure skating at the Winter Olympics on the TV: They can see the sport performed in the sequin-covered flesh this weekend when Disney on Ice takes over Verizon Center for brief, unabashedly sparkly run.
