Washington is starting Wednesday, October 28, around 52 degrees, with low clouds favored across the region and patchy fog expected before 10 a.m. The fog should thin as the morning wears on, giving way to partly sunny skies and an afternoon high near 68 degrees. Rain is barely in the picture.

Foggy Start, Mild Afternoon

Light onshore flow is possible, according to the National Weather Service. Temperatures should climb through the upper 50s by midmorning and reach the upper 60s during the afternoon, while clouds may become more noticeable later in the day.

Thursday And Friday Bring The Warm-Up

Fog may return after 11 p.m. Wednesday and linger into Thursday morning, when temperatures fall to around 50 degrees before rising to about 72. Thursday should turn mostly sunny after the fog clears, while Friday looks like the warmest day of the stretch with sunshine and a high near 75.

Halloween Looks Comfortable

Saturday, October 31, should be mostly sunny with a high near 66 degrees, followed by a mostly cloudy night with a low around 49. That keeps Halloween plans largely dry and comfortable, although a jacket will come in handy after sunset.

Rain Chances Return Sunday Night

Sunday stays mild but mostly cloudy, with a high near 69. Mentionable precipitation chances hold off until Sunday evening. Shower chances increase Sunday night and Monday, reaching about 30% Monday as temperatures remain mild near 68 degrees, with another chance of showers continuing into Tuesday.

No District Weather Advisories

Washington has no active watches, warnings or advisories in the current forecast. The National Weather Service says light onshore flow could push some sensitive shoreline locations closer to minor tidal flooding during evening tide cycles, particularly around Alexandria and Annapolis.

The latest outlook adds a foggier Wednesday morning and shifts the wet-weather focus to Sunday night and Monday, updating the earlier Hoodline forecast that emphasized the warm Halloween stretch.
