An increase in moisture along with the warmer temps will bring a threat for fog as winds will be light to calm overnight. Best chances for fog will be along and west of Hwy 17, and have included patchy fog mention for now.

Tuesday through Wednesday, Gradually strengthening southwesterly flow will prevail through mid-week. Temperatures will climb in response to this WAA regime, with highs increasing to the upper-60s Tuesday and around 70 Wednesday (low 60s the beaches and OBX). A weak low traveling along a coastal trough could produce some light showers on the ctrl and srn OBX, but bulk of moisture should remain out over the gulf stream and pops on OBX remain 20% or less.
Thursday through Friday, A dry backdoor cold front will push across ENC Wed night as a shortwave trough swings quickly across the mid- Atlantic.
