SYNOPSIS
09/133 PM.
Benign weather will continue through this week, with a warming trend continuing through Thursday. High temperatures will be well above normal through at least Friday. Offshore flow will produce locally gusty canyon winds in the mornings.
LONG TERM (SAT-TUE)
09/141 PM.
A shortwave trough is expected to arrive to the area on Saturday reducing 500mb heights to around 578 dam. Also, gradients look to increase to near neutral according to ECMWF guidance. About 50% of ensembles have weak onshore flow which would be sufficient for night through morning low clouds and fog (likely dense) to return to some of the coasts. More support on Sunday.
Max Temperatures are expected to cool 1 to 3 degrees on Saturday. Another 3 to 6 degrees of cooling is expected on Sunday. However, we will stay above normal by 3 to 6 degrees across csts/vlys and 6 to 12 degrees across the interior. There is decent agreement on reinforcing ridging early next week which would likely result in offshore flow, less clouds, and another increase in temps.
The ECWMF/AI show some support for troffing and rain chances to return after the 20th, but its minimal and low confidence at this time.

MARINE
