.SYNOPSIS...
West to northwest winds will continue to strengthen Tonight as a dry
cold front moves across the area. Small Craft Advisory conditions
will persist over the local waters Tonight and continue until
Thursday morning. A high pressure center will build into the area
Thursday into Friday and then shift offshore by early Saturday ahead
of the next frontal boundary. This front will likely remain dry as
it crosses our local waters on Sunday night. Strong high pressure
building to the north of our region in the wake of this frontal
passage will result in strengthening northerly winds on Sunday night
that will shift to northeast on Monday. Small Craft Advisory
conditions are likely throughout our local waters from Sunday night
through Monday night.
