Washington, D.C. A sharp autumn cooldown will bring a dramatic temperature change to Washington, D.C., this weekend, with afternoon highs plunging from the lower 80s Friday into the mid 50s Saturday before gradually recovering early next week.
According to the National Weather Service Baltimore/Washington office, Washington is expected to reach 82 degrees Friday before temperatures fall to just 56 degrees Saturday. The 26 degree decline will mark a significant shift following unusually warm October conditions across portions of the Mid Atlantic.
The colder weather will follow another round of showers Friday, with sunshine returning for the weekend.
Saturday Brings Sharp Cooldown, Chilly Night Friday's forecast calls for showers becoming likely after 2 p.m., with a 60% chance of precipitation. South winds of 10 to 15 mph could gust as high as 29 mph before cooler conditions arrive.
Showers will remain likely Friday evening, mainly before 8 p.m., as temperatures fall toward 48 degrees overnight.
By Saturday, Washington will experience considerably cooler weather, with sunshine and afternoon temperatures reaching only 56 degrees.
The coldest conditions are expected Saturday night, when clear skies accompany temperatures falling to approximately 39 degrees.
Sunday will remain cool but sunny, with afternoon highs recovering slightly to around 61 degrees.
The transition follows a broader national weather pattern highlighted by NOAA, which expects strong Canadian high pressure to bring a substantial cooldown across much of the central United States late this week.
While the national outlook identifies potential freezing temperatures in portions of the central U.S., Washington's supplied forecast keeps overnight lows above freezing.
Sunshine Returns as Temperatures Recover The cooler conditions will gradually ease as the new workweek begins.
Monday will bring sunshine and a high near 65 degrees, followed by partly cloudy skies and temperatures around 48 degrees overnight.
By Tuesday, afternoon temperatures are expected to reach approximately 68 degrees under mostly sunny skies.
For residents across Washington and nearby communities, the most noticeable change will be the contrast between Friday's summerlike warmth and Saturday's cooler conditions.
The National Weather Service forecast indicates dry weather from Saturday through Tuesday in Washington, offering several days of sunshine following Friday's showers.
