Other than a few fair weather clouds over the next couple of hours, skies will remain clear through the period. Some short range guidance is depicting the development of patchy radiation fog late this evening, but with a weak frontal boundary already beginning to pull drier air into the region, opted to wait to actually see fog development before biting on that trend. Behind the weak front, high pressure will quickly traverse the region Tuesday with northeasterly winds veering southeast during the afternoon as the high shifts east of the region.
