Our third Nor'easter in about 2 weeks is on the way this evening into early Tuesday morning. It looks like this storm will track close enough to the coast to provide a brush of precipitation to portions of the area. The greatest impacts look to be south and east of Baltimore this evening into early Tuesday morning.
Precipitation looks to filter in after midday and should start to get going between 4-6pm. Most of the activity will be light thanks to the dry air that was in place from the early morning hours. Rain and snow will be the primary precipitation type. With that said you combine the precipitation type with a high March sun angle and you get wet roads with limited problems. Now a refreeze could occur during the overnight period as temperatures fall below freezing creating a few icy patches mainly east of the city.
Most locations look too hang out in the dreaded "Snow Hole" where a dusting of snow may be the normal on those non paved surfaces. If you want to see the snow you have to head west into the mountains of Maryland where 4-8"+ of snow is expected along I-68 and US-219 from Frostburg to Deep Creek Lake. The ski resorts such as Wisp will love this as ski/snowboard season continues to hang on.
Once again this is not a storm for Maryland but if you want really big snow and blizzard conditions just head north up I-95 to Boston where 8-14"+ of snow is expected.
