.SYNOPSIS...
A frontal boundary will push southward through the local waters
tonight. Dense sea fog development will be possible across the
nearshore waters this evening. Northeast winds briefly surge in the
wake of this frontal passage on Saturday with Small Craft Advisory
conditions expected. Meanwhile, a winter storm developing over the
deep South on Saturday and Saturday night will shift northeast,
lifting a warm front northward across our local waters on Saturday
night. Winds will shift to south and then southwest on Sunday ahead
of another cold front, which could be accompanied by a few
thunderstorms on Sunday night. Arctic high pressure will then build
into the southeast states in the wake of this cold frontal passage
early next week, continuing Small Craft Advisory conditions into
early next week as breezy northwest winds shift to north while
strengthening further on Monday night.
