9:20 p.m. update: Except for some flurries mainly in the far north suburbs and along the west side of the Bay, snow from the west has not made it over the mountains. A few flurries or snow showers remain possible through evening but little to no accumulation is expected.
From 5:10 p.m... It’s been another cold day around here, with highs topping out mainly in the mid-30s across the region. Skies that have been filled with lots of clouds temporarily showed a bit more clearing this afternoon, but clouds thicken back up as the next clipper pushes in during the evening. Snow? You probably know our “dusting to a bit more” story by now!
Through Tonight: The initial push of snow is slow, but far western ‘burbs may see some light activity between now and 6 p.m. or so, before things start moving east a bit more. Flurries or light snow (possibly mixed with briefly heavier bursts) then last until about midnight. In places that get accumulation locally, the range should be about a dusting to 1/2”. Far northern spots have the best shot at a bit more than that range (up to 1” or so), and southern areas might not get any accumulation at all as precipitation is most likely from D.C. and to the north. Temperatures are also a bit more marginal for accumulation the further south you go. Overnight lows range from the mid-20s to near freezing.
Tomorrow (Tuesday): We probably don’t have an easy time clearing out, so we’re looking at mostly cloudy to fully cloudy skies throughout the day. Afternoon temperatures head for the low-to-mid 40s. Another weak clipper is also on the way toward us, but it should hold off till the overnight, and appears quite moisture starved even compared to recent systems.
