  1. From LWX (4:33 AM) .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... Low pressure will traverse the area Friday. It`s weak, but there`s notable warm advection in the 850-700 hPa layer, tucked under a modest coupled upper jet structure and mid-level PVA. Given the cold temperatures, any precipitation that falls will be snow and have no trouble sticking. East of the mountains, lift is focused in the dendritic snow growth zone, so despite low-level dry air believe there should be at least some steady light snow in the I-81 corridor and near/north of US-50. Along and north of I-70, moisture and lift are a bit better and this is where the best chance for plowable snow exists east of the mountains. As far as the ridges of the Allegheny Highlands go, lift here is actually a bit below the dendritic snow growth zone. Cold temperatures should yield ratios close to 18:1, but with low inversion heights and less than ideal wind trajectories, current most likely forecast is for sub-warning level snow (solid advisory, 3-6"). Therefore, have opted not to go with a watch at this time. Advisories will likely be needed over the mountains and in northern Maryland (especially given the cold ground and potential impact) for Friday, if current forecast projections remain on course.
