D.C. area forecast: Cold front brings rain today, then wonderful weather returns

4:35 p.m. update: Showers, some heavy, have overspread much of the area during the last few hours. This activity will continue through the evening as a cold front still to our west traverses the area. Intensity should vary, with some of the heavier stuff right in the beginning and along the front itself. Additional heavier patches are likely to form as well. If headed out, plan for it to be wet! Still looking for this to wind down somewhere near midnight (plus or minus an hour or two). Temperatures remain fairly steady in the upper 60s and low 70s, falling more after sunset.

Below from 5:00 a.m.: D.C. fell below normal for the year in the rain department this past week, and we’re now more than 3.5″ below normal during the past two months. Just keep that in mind if/when it rains on your weekend! Happily for those wanting to spend time outdoors, the rain won’t be the whole story of the weekend, though there could be a good 6-10 hour stretch, or so, where it’s hard to stay dry.

Today (Saturday): We could see showers as early as morning, but any in that time should tend to be on the minor side. Rain odds go up heading through the day, becoming likely (80% chance) during the afternoon. Given abundant clouds, and that we’re past the main heating season, any rumbles should come from storms below damaging levels. Rain probably holds off long enough to allow temperatures into the mid-70s, and perhaps even up toward 80 should it hold off through mid-afternoon. Confidence: Medium

Tonight: Showers could remain numerous into the evening while the front slowly progresses through. As time passes, it all shifts east. If we’re lucky it’ll move out in time for the Nats to get a game in, but that’s going to be tricky given the forecast for the day. By and after midnight should be drier for sure. Lows are mainly in the upper 50s and lower 60s, maybe mid-60s downtown. Winds kick up from the northwest. Confidence: Medium

Tomorrow (Sunday): Though the main batch of rain is well east, and much of the day should be dry with at least periods of sunshine, a small cold pocket and associated energy passing into the area could spark an isolated afternoon shower. Highs are largely in the low-to-mid 70s. Winds are from the northwest around 10 to 15 mph. Confidence: Medium

Tomorrow night: Northwest gusts of the day wane, and skies are partly to mostly clear. Our first night of autumn fits the bill, with a wide range of temperatures on hand — as cool as the mid-40s in the outlying suburbs to nearer the mid-50s downtown. Just a light breeze from the northwest. Monday morning river and valley fog? Confidence: Medium-High

A LOOK AHEAD

On Monday, we welcome back fall perfection. High pressure building toward the area from the northwest should do a good job of keeping additional tropical moisture well to our southeast. We’re stuck with lots of sunshine and brilliant temperatures in the near 70 to mid-70s range. Confidence: Medium-High

Tuesday features more in the way of that sunny stuff following another cool morning. Since the high will be trending overhead, temperatures start to moderate again, hitting at least the mid-70s if not the upper 70s. This is a trend we should see throughout the rest of the week — a smidge warmer each day. Confidence: Medium
