An Arctic front approaching from the Great Lakes will cross the region this evening. This will bring a reinforcing shot of unseasonably cold and blustery conditions. Snow showers are likely over the Allegheny and Potomac Highlands tonight, and a few flurries are possible east of the mountains this evening. High pressure will build from the midsection of the country toward the Mid-Atlantic Wednesday into Thursday resulting in a continuation of below normal temperatures.
