Today (Sunday): I’m going to call it a nice day today, but hold off on the official Nice Day Sun given the potential for some cloud cover from time to time. Still, the day should see a good deal of sun overall, and not a whole lot to complain about. Winds are light out of the south/southwest, and highs get to the upper 70s to near 80. Confidence: High
Tonight: Clouds increase a bit more overnight as light winds from the south bring in moister air. An isolated shower or two is possible south of the area toward central Virginia, but around here we should just see partly to mostly cloudy skies. Overnight lows reach the upper 50s to mid-60s (suburbs to city). Confidence: High

Tomorrow (Monday): A storm system slowly moves our way from the southwest. But the risk of rain here should hold off for much of the day, leaving us with partly to mostly cloudy skies and highs in the mid-70s to near 80. A few showers could arrive during the afternoon (30-40% chance). Confidence: Medium
Tomorrow night: Low pressure still to the southwest starts to ride up the Appalachians. That keeps the best chance of rain to our west, toward and over the mountains. But we still stand a 50% chance of mainly light to moderate showers here in the D.C. area. Lows are mild, in the mid-to-upper 60s under cloudy skies. Confidence: Medium
The way it looks now, the best chance of moderate to heavy rain stays west of the area Tuesday morning, with a continued 50% chance of mainly light to moderate showers in and around D.C. as highs head toward the mid-to-upper 70s. As we get into afternoon, our odds of steadier, heavier rain increase to around 70%, and we could see some thunderstorms too. Confidence: Low-Medium
Shower/storm chances stay up around 70% into Tuesday night. Some areas may see total rainfall amounts approaching or over an inch, though confidence in just how much rain will fall around D.C. compared to areas off to the west is on the low side. Rain should taper toward morning with overnight lows near 60. Confidence: Low-Medium
Rains should be ending during the early morning hours Wednesday with clearing skies to follow. Despite the increasing sun, cool breezes behind a cold front should limit highs to the 70s. Confidence: Medium
