PM Update: Winter weather advisory tonight into Thursday AM, light accumulation possible Posted at 04:20 PM ET, 01/23/2013 Winter Weather Advisory midnight through 9 a.m.* Coming off our coldest morning in almost four years, today's high at or around 27 degrees in D.C. is as cold as, or colder, than we've seen in the last two winters. While the "deep freeze" presses on, a small clipper system is set to produce some light snow across the area tonight into early tomorrow. No big accumulation expected, but with temperatures as chilly as they are, anything that falls shouldn't have trouble sticking. Through Tonight: Clouds continue to thicken and lower as the clipper moves our way. Snow showers and areas of light snow should begin to move into the area in the period of late evening to around midnight, with precip chances then possibly lasting into morning. Most local spots should see between about a coating and 1," with some heavier amounts nearing 2" possible, particularly south of the District. Lighter numbers may occur to the north. Lows reach the mid-teens to near 20. Link: How to list your weather-related closings and delays Tomorrow (Thursday): There's a chance some light snow or snow showers linger into early morning, but they should be out of here quickly thereafter if so. Clouds should also break pretty rapidly as the day goes, leaving us mostly sunny for a majority of the time. Unfortunately, winds kick up a bit behind the system, with sustained winds near 20 mph at peak and gusts past 30 mph a good bet. That'll make highs in the upper 20s to near 30 feel a good bit chillier. Helping the homeless in the cold: Though area residents might be said to overreact to the cold, those who have no choice but to spend the time outside may need assistance. Mark Berman has compiled a list of numbers for you to call should you see a homeless person or anyone else in need of shelter during this cold spell.
