This evening’s radar looks a lot like winter, as snow squalls have moved off of Lake Erie into Pennsylvania. The main energy and moisture will remain in the mountains, but it also signifies the core of the cold air that has yet to arrive. The wind today was just the precursor. Baltimore’s BWI did reach a peak wind gust of 40 mph. It was stronger in the mountains to our west, but we all felt something.
Note: This post comes with a heavy heart during the terrorist attacks in Paris. My hope is to provide a brief distraction and shift the attention towards the window (or radar)
The next thing to watch will be the upper level energy. Vorticity is a measure of spin aloft that enhances rising air and building showers, especially with added moisture from the Great Lakes. The snow squalls mark that energy, and the leading edge with the colder air will slip south this evening. There is a chance of flurries making it farther south overnight into early Saturday morning. But only a very slim chance they reach Baltimore or south. However, there will be some showers in the mountains for sure. Perhaps enough snow showers to coat the ground with fresh early season powder in Wisp, Seven Springs, and Snowshoe Mountain ski resorts.
