Upper level low pressure center sliding east from the Great Lakes into New England today. The well defined frontal boundary continues to spread south & east across the Mid Atlantic states this afternoon. Behind the front we have dry & much cooler air already building into our western slopes. Cold air mixing into our area under a northwesterly upper air flow will keep things breezy and cool as a few mountain rain showers linger into the afternoon. Canadian high pressure will provide mostly clear skies overnight as temperatures fall into the low 40s/upper 30s in the mountains. This will set up ideal conditions for dense valley fog to build into Friday morning.

     A few passing showers may brush extreme southern West Virginia during the day Friday. Otherwise that Canadian high pressure will keep a good hold over the Great Lakes and Mid Atlantic states through the weekend. This will keep the forecast for the mountain state dry and mainly sunny Saturday & Sunday. Weekend temperatures will gradually return to normal with daytime highs reaching the low to mid 70s. At night temperatures will fall into the mid 40s this weekend. Then the next frontal boundary will bring another chance for rain by Tuesday next week.
