High pressure aloft will remain near the West Coast into next
weekend. Combined with weak onshore flow...this will keep high
temperatures near the coast near average with inland high
temperatures around 10 degrees above average for inland areas. The
marine layer and weak onshore flow will bring areas of night and
morning low clouds and fog to coastal and some valley areas at
times. Coverage will be quite patchy this morning. The higher
resolution models bring greater coverage for tonight into Monday
morning with deepening into portions of the inland valleys for
Monday night into Tuesday morning and Tuesday night into Wednesday
morning. The marine layer could be a little shallower toward the end
of the week into next weekend if high pressure aloft strengthens
further as shown by the GFS... European model (ecmwf)...and their respective ensemble
means. That could push high temperatures for next Sunday to around 5
degrees above average near the coast and 15 degrees above average
for inland areas.
