FORECAST IN DETAIL


Today (Wednesday): A mild breeze from the southwest helps temperatures several degrees higher than yesterday. It’s a pretty darn nice one out there with partly sunny skies and highs in the mid-to-upper 50s. Just a slight chance of a brief afternoon shower as a mainly dry cold front approaches. Confidence: Medium-High

Tonight: As that moisture-starved cold front comes through, can’t rule out a slight chance of a brief evening shower. Otherwise, we’ll see skies become mostly clear with lows mostly in the 30s, maybe up near 40 at Reagan National. Confidence: Medium-High

Tomorrow (Thursday): High pressure should keep us mostly to partly sunny through the morning. But it may weaken enough to allow clouds to stream in during the afternoon as a system approaches from the southwest. Temperatures are cooler than today, but still a good deal above average with highs near 50 to the mid-50s. Confidence: Medium-High

Tomorrow night: Skies turn mostly cloudy Thursday night, and the clouds might squeeze out a shower or two (20-30% chance). The insulating effect of the clouds means mild lows for this time of year, in the mid-30s to low 40s. Confidence: Medium

A LOOK AHEAD

Friday doesn’t look like a rainy day at this point, but we do run a bit higher risk (40% chance) of scattered showers. It’s possible a steadier area of rain makes a run at us mid-afternoon into evening, but it may also veer north of the area. We’re still on the mild side despite mostly cloudy skies, with highs near 50 to the low 50s. Shower chances decrease overnight or toward morning with lows not very low at all - in the upper 30s to mid-40s. Confidence: Low-Medium

Saturday is shaping up as an absolute winner with partly sunny skies and a warm flow from the south pushing highs into the 60s, followed by Saturday night lows in the 40s. Sunday is still warm, with highs probably into the 60s again. But it does look cloudier with maybe some showers (20-40% chance). Confidence: Low-Medium
