We had a bit -- and I mean a bit -- of surprise snow action today, mainly north of the Beltway. That’s headed to our east now and even a few peeks of sun are shining through today’s persistent clouds. Highs ranging from near 40 to the mid-40s are close to or slightly below normal, but with light winds most of the day it has not felt too cold out there.
Through Tonight: We should trend clearer through the night as the first clipper system heads away, though it seems unlikely we head totally clear ‘till between midnight and sunrise. There could even be another bout of flurries or snow showers for parts of the area as well. Overnight lows should range from near 30 to the mid-30s.
Tomorrow (Friday): Another small storm system will roll by to the north during the day and into the night, but it’s a little stronger, and we’re going to have warmer air riding in concurrently. The first half of the day should end up pretty sunny, though clouds may be on the increase by midday or early afternoon and we could end up partly-to-mostly cloudy for a time late. Highs head for the low-to-mid 50s!
Arctic blast: We’re closing in on the coldest time of year on average in D.C. Almost right on time, we’re looking at our first significant Arctic outbreak of the year. After a weekend of warmth, temperatures should come way down on stiff northwest winds Monday as cold air filters in. Tuesday-Wednesday look downright cold. Highs ranging from near 30 to the mid-30s appear in reach. Lows dipping into the teens, at least outside the Beltway, by Wednesday morning are also a good bet. One “lucky” facet for people who easily freeze is that this cold shot will traverse mostly snow-free land to visit the area, which may help moderate temperatures slightly compared to their potential.
As comparison, 2011 had 19 days in January below 40 degrees for a high in D.C., and three at freezing or below.
