Discussion...for extreme southwestern California including Orange...
San Diego...western Riverside and southwestern San Bernardino
counties...

It was a very warm day today across the region. Temperatures
reached anywhere from 3 to 7 degrees above normal. Onshore flow
is weakening and nearly neutral due to slack gradients. The marine
inversion is also quite weak and shallow. This pattern will
continue with the marine influence limited to along and near the
coast.

Upper level warming will be limited but continued through
Thursday...therefore have nudged temperatures up a couple of degrees for
Thursday with the warmest temperatures across the Coachella Valley
approaching 110 degrees likely Thursday afternoon. Onshore flow
should commence on Friday allowing for some cooling near the coast
but continued hot weather inland with temperatures still likely
several degrees above normal.
