(This evening through Monday) Issued at 1227 PM PDT Sun May 26 2024 What a difference 24 hours makes with regards to sensible weather. Afternoon satellite shows much more sunshine being seen across the Bay Area and Central Coast this afternoon. Given greater insolation this afternoon it has led to warmer temperatures even with onshore flow. 24 hour trends show many spots running 2 to 6 degrees warmer this afternoon. A nice pleasant afternoon with temps maxing out upper 50s and 60s coast and 70s to low 80s inland. Rounding out the holiday weekend: The marine layer hasn`t gone away. The low clouds over the coastal waters will spread along the coast and locally inland again. Not expecting much in the way of drizzle, but some patchy fog will be possible. For Memorial Day, morning clouds will roll back to the coast by late morning/early afternoon. The warming trend observed today will continue tomorrow.

The warming trend from the weekend will briefly pause mid-week an upper level trough sweeps through the PacNW shunting our ridge of high pressure southward. The temperature pause will brief as high pressure re-builds by Friday/Saturday allowing for even warmer temperatures to develop across the interior. Night and morning low clouds clearing the coast each afternoon will continue.
