The National Weather Service in Washington D.C., has issued a special weather statement early this morning for residents in the D.C. metropolitan area, including numerous adjacent counties across Maryland, Virginia, and West Virginia. The alert warns of patchy dense fog this morning, as reported on the NWS website. The fog, characterized by visibility dropping to less than a quarter of a mile in some areas, is the result of a mixture of light winds and persistent low-level moisture.

According to the detailed forecast, today holds a slight chance of showers after 2 pm, with a calm wind picking up from the south in the afternoon. The high is expected to be near 82 degrees, while the chance of precipitation remains modest at 20%. Tonight, the likelihood of precipitation increases to 50%, with "a chance of showers and thunderstorms, mainly after 3am." The NWS predicts a cloudy night with a low around 69 degrees, affected by southeast winds of 3 to 5 mph.

Looking ahead, Thursday is set to bring more active weather, with "a chance of showers and thunderstorms, then showers and possibly a thunderstorm after 8am." The weather service, noting an 80% chance of precipitation, anticipates new rainfall amounts to range between a tenth and a quarter of an inch—with the possibility of higher amounts during thunderstorms. Similar conditions persist into Thursday night, carrying an 80% chance of precipitation and showers, possibly accompanied by a thunderstorm before the skies begin to clear post-2am.

The rest of the week's forecast oscillates between chances of showers and overcast skies, with daytime highs hovering close to the 80-degree mark. The chance of precipitation varies daily, never quite dissipating, ranging from 30 to 40%. Every evening, a chance of showers repeats like a mantra for the region, with the sky reluctant to part from its cloudy countenance, keeping the low temperatures consistently in the mid-60s.
