Breezy northwest winds expected into Tuesday as high pressure builds into the region, resulting in Small Craft Advisory conditions through much of Tuesday before diminishing. Easterly flow returns Wednesday into Thursday as the surface high moves to our north and over the western Atlantic. A weak system approaching the area late in the week could bring a few showers, otherwise expect winds shifting northerly over the weekend as high pressure returns.

UPDATE... Added small craft advisory for the Tampa Bay waters and Charlotte Harbor through tomorrow morning.

Prev /issued 720pm EST Monday Nov 30 2020/

FOR THE EVENING The cold front that moved across the Florida west central and southwest Florida has pushed well south of the forecast area. Canadian high pressure is building over the region in the wake of the front with colder drier air advecting across the area. The airmass contrast to the very warm conditions of the past several weeks will make for an abrupt and noticeable change as temperatures drop into the mid to upper 30s north...in the 40s central...and the upper 40s to lower 50s south overnight. Northwest winds of 10 to 15 MPH will make it feel even colder. Considerable cloudiness remains over the region at this time, and cold air advection over the warm waters of the eastern Gulf of Mexico will create a large area of cold air strato-cu which will advect onshore given the west northwest trajectories off the water. However inland areas well away from the coast may clear later tonight. As winds begin to veer a bit on Tuesday, strato-cu cigs will be confined to over the water and possibly along portions of the immediate coast, with skies becoming sunny elsewhere. Temperatures will struggle to climb into the mid to upper 50s north...upper 50s to around 60 central...and the lower to mid 60s south.

Tight gradient over the coastal waters will continue to produce advisory level winds and seas tonight...with rather rough conditions for boaters. Winds and seas will gradually begin to subside Tuesday and Tuesday night...however area beaches will be impacted by high surf and strong rip currents through Tuesday.
