D.C. area forecast: A gloomy Saturday and a glorious Sunday

2:40 p.m. update: A batch of widespread light to moderate rain is pushing through the area now, and the persistent clouds along with at least occasional showers have kept temperatures in the near 70 to mid-70s range this afternoon. It appears that once this batch passes through D.C. over the next hour or two, shower activity will become more isolated to scattered. However, some drizzle may occur in lulls as well. Rain drops remain possible into the evening, perhaps as late as midnight or so, but in diminishing likelihood overall as time passes.

Radar as of 2:40 p.m. shows widespread shower activity over the area, moving southeast.

From 5:00 a.m.: After a string of at least semi-active weather days across the region, we’ve got one more today that’s not quite a walk in the park. That said, it shouldn’t be the worst weather day ever either. Not quite the weekend weather we’ve gotten used to in recent months though. Fear not, tomorrow looks quite nice. And after that, a string of benign weather is likely to continue.

Today (Saturday): Winds out of the east keep us “wedged” in with cooler air for the day. Add in high levels of moisture and you’ve got a recipe for periodic showers, sprinkles or even some general drizzle. Timing showers is always tricky till they pop up, but it appears there may be a heightened risk for more widespread activity during the first half of the day, but with at least hit-or-miss shower odds continuing through the afternoon as well. Not the nicest Saturday for outdoor plans ever, but hopefully not entirely disruptive either. I think we’ll see enough clouds and rain around to keep most spots in the 70s. Maybe shooting for mid-to-upper, but that could shift a few degrees either way depending on the extensiveness of rainfall activity. Confidence: Medium

Tonight: A risk for showers or sprinkles persists in waning fashion through the evening. Skies want to stay fairly cloudy early, but we should see increased clearing after midnight and shower odds drop to near zero. Humidity also starts to lessen as we go, heading back toward the tolerable range by sunrise. Lows are mainly in the low-to-mid 60s. Confidence: Medium

Tomorrow (Sunday): If there’s a competition for pick of the weekend, Sunday easily wins it. High pressure is increasingly in control, meaning we should see plentiful sun. Mostly sunny maybe? Likelier we trend that way by afternoon at least! Humidity is fairly low, as dew points head into the 50s. It could be a “Nice Day stamp” type of day with light and variable winds. Confidence: Medium

Tomorrow night: Mostly clear conditions persist, as do light winds and comfortable temperatures. Humidity is also fairly low still. Temperatures head for the upper 50s in the cooler suburbs to the low-or-mid 60s downtown. Confidence: Medium

A LOOK AHEAD

Monday gets us started on what could be a mostly boring weather work week locally (depending a bit on what that Atlantic tropical system does).  High pressure continues to dominate the region, helping cloud cover stay at a bare minimum. Under mostly sunny skies, afternoon temperatures strive for the low 80s or so. The evening and overnight should be delightful as well, with lows heading for the near 60 to mid-60s range.   Confidence: Medium

High pressure remains fully in control on Tuesday, so we’ve got more blue skies and mild temperatures on tap. A return flow of warmer and muggier air may be more noticeable, but probably not too bad either. Slightly more humid conditions are possible as highs rise to the low-and-mid 80s. Confidence: Medium
