The warming trend that developed Tuesday is coming to an end with a notable cool down for most of the Central Coast on the way for Friday.
Gale force northwesterly winds are allowing for substantial temperature gradients.
After a morning of low clouds at the beaches, those strong winds will mix out the marine influence by Thursday night.
Gentle to moderate winds and a persistent marine layer with fog and mist in the coastal regions start Friday. More seasonal temperatures are expected to begin Friday and last through Wednesday.
A weak upper level trough will create a cooling effect for the Central Coast on Friday, bringing temperatures down several degrees inland and along coastal valleys.
Coastal low clouds and fog will spread into coastal valleys Thursday evening, retreating to the coastal areas late Friday into Saturday.
Building high pressure next week will elevate temperatures, bringing inland valleys to slightly above normal temperatures by the start of the workweek.
