.DISCUSSION...
Low pressure will pass south of the area today, resulting in mostly
cloudy skies and below normal temperatures and light west-northwest
winds. A surge of northwesterly winds could produce a few gusts
up to 20 knots tonight, but at this time, the strongest winds are
expected over the main channel of the bay.
High pressure builds overhead Monday, beginning a warming trend
through Tuesday. Gusty southerly winds will develop by Tuesday
afternoon which may require a Small Craft Advisory. A cold front
will reach the area Wednesday, bringing the next chance
of light rain showers. Gusty northwesterly winds in the wake of the
front may require a Small Craft Advisory.
The current water temperature is 60.
