Today (Monday): The day may get off to a soupy start with clouds, fog and perhaps an isolated shower (20 percent chance). During the course of the morning, skies should brighten as a push of southerly air (winds at 10 to 15 mph) boosts temperatures through the 50s. During the afternoon, we might see a little sun, with a wide range of high temperatures in play. 70 is possible with enough sun, especially south of town. North of town clouds may hold temps closer to 60. After 4 p.m., there’s a 20-40 percent chance of showers (best odds west of town), with maybe a rumble of thunder.

Record warmth cannot be ruled out. Today records are: Reagan National at 68°, Dulles at 71° and BWI at 69° - these are all from 1979. Confidence: Medium

Tonight: There’s about a 50/50 chance of showers (with maybe a little thunder) early in the evening but widespread meaningful rains are iffy. After midnight skies slowly clear, with lows 40-45 (suburbs-city) Confidence: Medium-High

Tomorrow (Tuesday): High pressure settles in from the west generating sunny skies but cooler temps. Highs are close to average - right around 50. Winds are from the north at 10-15 mph. Confidence: Medium-High

Tomorrow night: Clear, calm, and cold. Lows range from the mid-20s in the cooler suburbs to the low-to-mid 30s downtown. Confidence: Medium-High


Wednesday through Friday are mostly sunny (perhaps some high clouds Wednesday, especially east and southeast of town) with highs in the upper 40s to low 50s, with overnight lows in the mid-to-upper 20s in the colder suburbs to the low-to-mid 30s downtown. Confidence: Medium

Clouds increase Saturday ahead of the next weather system, with highs 50-55. There’s a chance of rain Saturday night into the first half of Sunday, with lows 40-45. After any morning showers, Sunday may see some partial clearing late, while it turns breezy, with highs 45-50. Confidence: Low-Medium
