Much like the March on Washington 50 years ago, today’s high in D.C. was in the low 80s. In fact, we might have matched it exactly at 83. Other than that, the day wasn’t too similar, with this go being plagued by showers and high humidity. The rain threat diminishes this in the hours ahead, but we stay in a warm and muggy pattern for the next few days.
Through Tonight: Following several batches of light showers today, we may see a few more wander by through evening (50% chance), though the brunt of future activity should try to pass to our west. As we get to sunset and beyond, the shower threat should quickly dwindle, with isolated activity through perhaps midnight. Lows make the upper 60s to mid-70s. As winds go light, some fog may form thanks to abundant low level moisture.
Tomorrow (Thursday): After some possible fog in the morning, clouds should be considerably less numerous than today, but we’ll probably still deal with them from time to time. No real change in humidity either, as dew points hover near 70 (or pretty gross!). Highs should mostly reach the mid-80s, let’s say 84-88 or so. It’s probably dry, though an isolated (10%-20% chance) late-day shower is possible. Winds are from the northeast around 5-10 mph.
Rim Fire: The fire burning near (and into parts of) Yosemite National Park is now the 6th largest in state history, burning at least 187,000+ acres as of this morning. It was 23 percent contained as of last report, and increased moisture in the region has helped firefighters in the last 24 hours or so. As far away as Nevada, air quality has at least briefly surpassed “hazardous” stages, according to The Weather Channel.
