One more busy weather day today and it could get interesting. That is if cold air arrives fast enough, and precipitation lingers long enough, to produce a parting shot of afternoon snow. Otherwise it’s damp, cold, and overall icky as far as pre-Thanksgiving travel goes. We dry out nicely tomorrow through the weekend, but don’t get significantly warmer until Sunday the way it looks now.

Today (Wednesday): Rain showers remain likely this morning but should become intermittent as temperatures hover near 40 to the mid-40s. Things could get a bit interesting this afternoon if precipitation lingers as colder air comes in from the west. Any leftover rain could change to snow showers and/or sleet (50% chance) from west to east between late morning and early afternoon.

We could see a light coating mainly on grassy areas during the early-to-mid afternoon, as temperatures drop into the mid-to-upper 30s and winds gust near 30 mph from the northwest, with even a 30% chance of up to 1/2″ and some slick travel in the far north and west burbs (e.g., Frederick, Loudoun, Fauquier and northern Prince William counties). Just a 10-20% chance of road impacts in the immediate metro area.

There’s also a 50% chance the precipitation dwindles or exits before it has a chance to turn into any meaningful snow and/or sleet. Confidence: Low-Medium

Tonight: We dry out during the evening as a brisk wind from the northwest gusts near 30 mph through the night. Skies become mostly clear overnight with lows dipping to the mid-to-upper 20s. Confidence: Medium-High

Tomorrow (Thanksgiving): It’s a tranquil Turkey Day relative to today. The storm is long gone with only cold left behind, as highs stall in the mid-to-upper 30s under partly to mostly sunny skies. Winds are lighter, but still a bit breezy from the northwest near 15 mph with some higher gusts. Confidence: Medium-High

Snow Potential Index

A daily assessment of the potential for at least ~1″ of snow in the next week, on a 0-10 scale.

1 (↑) Small chance of something more than conversational flakes today, mainly N&W. Even then likely under 1″.

Tomorrow night: Winds finally die down, becoming light during the evening and maybe calm for a time overnight. Lows bottom mainly in the 20s area-wide. Confidence: High

A LOOK AHEAD

With high pressure in control, we see quiet weather Friday through Sunday with somewhat of a warming trend. Highs should get to the upper 30s to near 40 on Friday under mostly sunny skies, while Saturday highs reach near 40 and Sunday highs head for at least the mid-40s beneath partly sunny skies. Winds are light throughout. Friday and Saturday night lows are only a bit colder than average, in the 20s to low 30s. Confidence: Medium-High
