BALTIMORE — Our powerful cold front that looks to move through Wednesday may only bring us rain here in Central Maryland but could actually touch off some snow in the mountains of Maryland and West Virginia. This includes such places as Deep Creek, Oakland, Canaan Valley, and Snowshoe. Garrett County of course is no stranger to snow this time of year. Flakes usually fly in the higher elevations of Western Maryland above 3,000 feet before Halloween.
Wednesday's front will bring a quick temperature drop and a stiffening northwesterly breeze which will ride up the western face of the mountain chain. Leftover moisture in the valleys will be picked up from these winds creating clouds and precipitation which could be in the form of snow with ample cold air in place the higher you go up. We call this upslope flow. During the Summer of course it can produce gully washing thunderstorms and in the winter substantial snows especially in Garrett Co. where moisture can also be tapped into from Lake Erie.
This will not be a substantial event by any means with many locations seeing nothing at since forecast question remain to how much moisture will be leftover on the ground behind the front.Once again any accumulations that we do see will be in elevation above 3,000 ft. This would include parts of Keysers Ridge and Backbone Mountain in Garrett County. A few flurries could also be possible in Frostburg and Lavale but no accumulation is expected. No snow for those us here in Baltimore unfortunately but at least a sign that the season is changing for us snow lovers.
