A few days ago, we talked about whether or not it would be the front side or the back side of this complex storm system — or rather, cluster of storm systems — that would deliver the most potential for snow in Southwest Virginia. I leaned to the front side then, and it has dumped widespread 3-7 inch snowfall amounts on the Roanoke and New River valleys and nearby areas today. Accumulating snow might not be over, though I think the majority of it is for our neck of the woods. The next piece of upper-level energy approaches from the west overnight. While we were having our Palm Sunday snow today, this system was triggering severe thunderstorms north of Nashville in much milder air. As it approaches overnight, and also interacts with a low along the East Coast, it may spread snow back into the area late tonight or early Monday morning. Most forecast guidance suggests that the greatest emphasis of this storm will be north of Roanoke, more for the I-64 corridor and northward. But another inch or two of snow may be possible as it swings through. The one thing that gives me pause that it might be a little more is the heavy thunderstorms on the line today, and their remnants maybe bringing some heavier snow bursts. In any event, the area of snow is unlikely to be as large or as long in duration as today’s system was. Between now and the next wave, some scattered light snow, light drizzle or freezing drizzle will be possible.
It’s going to keep being wintry into midweek, with stiff northwest winds behind the tightening storm off the East Coast, upslope-driven snow showers, and perhaps even some Alberta clipper-like disturbances spreading yet more snow east of the mountains. Below normal temperatures will continue into next weekned. Beyond that, there maybe a few signs of the unseasonable cold breaking. Spring will win this battle eventually against this reluctant-to-start, yet reluctant-to-leave winter
