WINTER WEATHER ADVISORY from midnight until 10 a.m. Friday for Frederick and Washington Counties and points westward in MD, the Eastern Panhandle of WV and for Loudoun, Fauquier, Rappahannock Counties and points westward in VA. Snow and sleet may accumulate up to one inch at the higher elevations.

All of our attention is focused on the imminent development of a coastal low that is expected to become a powerful Nor’easter that could cause widespread blizzard conditions across portions of New England. Here at home, we will be on the fringes of the storm just as it begins to intensify. It’s position and track relative to our geographic area means we will experience only minor effects compared to our friends up north. Rain or a wintry mix will develop after midnight.

Surface temperatures will be critical across the metro area. As long as temperatures remain above freezing, this will have little impact. The potential issues will be in areas north and west of Washington where colder temperatures mean a combination of snow and sleet and freezing rain could total up to one inch. The best chance for that to occur will be in the ADVISORY area.

As the storm rapidly deepens and moves northeast of Washington tomorrow evening, strong winds will develop across the area. Flurries and snow showers will also be possible as colder air wraps into this headline-making storm. We will watch this storm closely as a change of a couple degrees in the forecast air temperatures could mean a change in the type of precipitation across the region.
