Loudoun County Weather Outlook for Wednesday, March 18, 2026

3/18/2026

Chilly but Calm, with a Warmer Weekend Ahead

🆒 Remaining Cold today

Pretty cloudy and cold, but the breezes have died down, and we should reach near 40°F.

🌥️ Near Normal Tomorrow

Thursday brings highs into the low 50s, closer to where we should be this time of year. Still mostly cloudy.

🌦️ Warming Into the Weekend

Friday stays cloudy with a slight chance of afternoon showers, but temps push near 60°F. Saturday, we're looking at the mid-to-upper 60s, and Sunday climbs into the low 70s, though another chance of showers moves in late Sunday.

🧥 Cooler Again Next Week

That Sunday night system ushers in a return to seasonable and then below normal temperatures. Monday highs back in the low 50s, Tuesday only in the upper 40s, with overnight lows dropping below freezing.

Nice to have a calmer stretch in the forecast after the wild stretch of weather we've seen lately!
