.SYNOPSIS...

Low pressure over the Plains will move off to the east tonight
pushing a cold front across the coastal waters. Strong southerly
winds and shower activity will end with the frontal passage. A
small craft advisory will linger through the night due to high
seas that will take awhile to decrease. High pressure will build
into the coastal waters from the north bringing a period of modest
offshore flow through the middle part of the week.
