* Winter weather advisory north and west of the District from 7 a.m. to 7 p.m. Saturday *

10:10 p.m — Forecast on track. Watch out for brief burst of snow early Saturday. Then mixed precipitation in the afternoon.

High-resolution models continue to support the idea of a very brief shot of snow early Saturday morning, moving through the region from southwest to northeast between about 6 and 10 a.m. The snow may briefly come down at a good clip and, with temperatures in the 20s, stick to untreated surfaces. However, it shouldn’t last more than an hour or two, which is only enough time to drop a dusting to an inch in most areas.

Then, we should get a pause in the precipitation before a round of rain and, in colder areas, freezing rain between mid-afternoon and early evening as spelled out in detail below.

We’ll be back with updates starting at 5 a.m. Saturday.

Despite the normal high temperature now being on the upswing after its wintertime low in the District, this was the first day with an actual high temperature below normal in more than a week. It’s been so warm lately, even slightly below normal feels rough in the shade, especially when wind is involved. The gusts of recent days will wane a bit through tonight as Saturday’s wintry mess moves this way.

Through tonight: High clouds are moving into the area this evening. The clouds will lower and thicken overnight. Temperatures will settle mainly to the mid-20s and upper 20s, but some spots may be a bit warmer or cooler. Light snow will probably break out from west to east as we head toward dawn. Winds will be light from the north late evening through dawn.

Tomorrow (Saturday): Light snow will be moving into the area around sunrise, then fairly rapidly shift east and northeast. It won’t last long, but it will be enough for a dusting to an inch locally — more to the north or west, with less south and east. A late morning and/or midday lull is a good bet before sleet turning to freezing rain and rain returns in the afternoon and lasts into the evening. Daytime temperatures around Interstate 95 and to the southeast will slowly rise toward the mid-30s and upper 30s, although they may continue to rise into the night. As one gets farther northwest, at least pockets remaining near or below freezing will be a possibility. Some slick travel is likely, especially early and as one heads north or west.

Sunday: Mostly sunny conditions will return. It will be seasonably chilly, with highs in the 40s. A northwest wind around 10 mph with gusts past 20 mph will keep it a bit blustery.
