Yes, there is a chance for a little snow this weekend. There, I’ve mentioned the “S” word…now to the specifics.
After a partly sunny day Friday (today) with a high temperature in the mid-40′s (F) high clouds will roll back into the area ahead of the next fast-paced system. Here is the forecast surface map for 7 p.m. this evening:
There are two approaching surface low pressure systems – which I’ve circled in black – that will affect our weather tonight and tomorrow. To provide a hefty snowfall for the ‘Burg these two systems would need to “phase”, i.e. join forces into one system that (a) pumps moisture up from the south while (b) yanking down cold air from the north. They will phase…but well off the coast, so it looks like we will only see light precipitation and only a few hours of frozen stuff before it all turns over to rain for the ‘Burg.
In fact, here is the official forecast text from the NWS Sterling office:
"THERE IS MORE UNCERTAINTY IN SNOW AMOUNTS FURTHEST SOUTHEAST OF THIS ADVISORY AREA FROM BALTIMORE SOUTHWEST THROUGH WASHINGTON AND INTO NORTH CENTRAL VIRGINIA MAINLY DUE TO UNCERTAINTY IN THE RAIN/SNOW LINE AND BOUNDARY LAYER TEMPERATURES"
Those words should sound familiar as they are applied to the ‘Burg quite regularly during the winter. However the rest of the text forecast – which I didn’t include – does hold out the possibility that things could change. Meanwhile here’s their forecast graphic for snow totals:
Sunday and Monday will provide a brief sunny respite between storm systems with high temperatures hovering around the 40 degree mark. Then New Year’s Day looks to usher in yet another storm system with another round of possible rain/snow/all of the above.
