Current-Overnight...Should continue to see a diminishing trend for
showers from KMLB south through the night with greatest chances

lessening of the pressure gradient as winds continue to slowly
decrease. Wind speeds will remain strongest along the east coast
with directional component across ECFL ranging from ENE to NE.
Winds above the surface will also remain a bit elevated continuing
to keep the airmass mixed enough to keep overnight lows generally in
the 60s. Cooler locations across the interior may realize U50s.

A High Surf Advisory remains in effect until 5AM Fri morning for
large breaking waves and possible minor erosion along the coast.

Fri...Surface high pressure continues to drift further into the
western Atlc with easterly winds and pgrad tight enough to keep near

the coast and further inland. Will keep PoPs at 20 percent or less
