Dry wx overnight with a mostly clear sky as the eastern seaboard is under the influence of an upper-level ridge. Cannot rule out early morning patchy fog, but it is not likely in most areas due to ~5 kt winds and dew pts generally being a least a few degrees lwr than temps. Pattern is also similar to Tuesday morning when there wasn`t much fog. Low temps in the low-mid 60s.

Sfc hi pres and upper-level ridging keep vfr conditions and SKC across the area this aftn/evening. With the sfc high offshore, winds will be out of the s/sw and up to 10-15 kt through sunset. Some guidance continues to be overly-aggressive with fog tonight, but sticking to mainly vfr conditions due to temp/dewpt forecasts tonight and winds ~5 kt. Best chance for low vsbys would be at KSBY where did include a brief period of MVFR vsbys similar to what happened this morning. Dry wx continues into Wed with a mostly sunny sky.
