Washington started Wednesday, April 8, 2026, with clear skies, a sharp chill, and temperatures in the mid‑30s at Reagan National before sunrise. A Freeze Warning is in place through 9 a.m., and frost has already shown up in low‑lying neighborhoods and the outer suburbs. Sunshine this afternoon should nudge highs into the mid‑50s, but another round of frost is likely late tonight, so gardeners and anyone with exposed outdoor plumbing will want to take it seriously.
Morning Freeze And Today's Forecast
Across the District, skies should stay mostly sunny with an afternoon high near 55°F and light east winds around 6 mph. Early today, some parts of the region can still slip to around 30°F, which is why the Freeze Warning holds through 9 a.m. On the water, Small Craft Advisories on the tidal Potomac and nearby Chesapeake waters back off by mid‑morning, and mariners are urged to secure small vessels and check local marina notices, according to the National Weather Service.
Tonight's Frost Risk
Tonight brings clear skies and light winds again, a setup for strong radiational cooling that can let many suburbs and sheltered low spots decouple from the daytime warmth and slide to or below freezing late Wednesday night into Thursday morning. Freeze Watches are already posted for much of the region for the late‑night period and could be upgraded to warnings in some locations after this morning's products expire. If you have tender plants, bring potted ones indoors or cover garden beds, and do not forget to protect exposed irrigation lines and outdoor faucets.
Late-Week Warm-Up
Later this week, temperatures start to behave more like spring, with highs near 63°F on Thursday and climbing into the 70s by Friday as winds turn first southeasterly and then southerly. Forecasts keep that warming trend going into early next week, with some spots potentially reaching the mid‑to‑upper 80s by Monday and Tuesday. It is a good window to plan outdoor time in the milder afternoons while still keeping an eye on cooler morning lows if you are managing plants or other sensitive outdoor gear, according to the National Weather Service.
Quick Tips
Before tonight, move sensitive potted plants inside or cover garden beds, and drain or insulate exposed outdoor faucets to avoid freeze damage. Boaters should hold off on departures until mid‑morning and double‑check conditions with their marina. Commuters can look for dry roads, bright skies, and cool but comfortable afternoons through the rest of the week.
