This is very reminiscent of the upper Plains. The footprints from earlier in the day are filled in, but it is hard to make measurements that prove that more snow fell.
5z HRRR has 0.3-0.4” precip after the changeover for many of us near 95. That number is fairly consistent across the models. A wind blown 2-3” is looking decent.
We don’t really care about the heavy stripe to the east because that is rain. The precip max to the west is in the favored spots, so no shock. We just need to score with what we get.
March 5, 2015. For no particular reason.

My brother moved to the Frederick area and that section that goes down to two lanes is awful. Every trip it is the same slow spots, before the bridge on 495 to get into Maryland and after Clarksburg.
