High pressure aloft near the West Coast and weak offshore flow
will bring warming through Saturday both inland and towards the
coast. Above average high temperatures will continue for inland
areas through early next week with gradual cooling the latter half
of next week. A return of a shallow marine layer and weak onshore
flow will bring slow cooling near the coast on Sunday...spreading
slowly inland next week.



High pressure aloft near the West Coast and weak offshore flow will
warm high temperatures 10 to 15 degrees through Saturday. Areas
near the coast may cool slightly on Sunday as a shallow marine
layer develops and weak onshore flow returns.

Satellite imagery shows stratus that had spread northward along
the northern Baja coast now drifting off the coast. There still
appears to be some very patchy stratus just off the coast of
central and northern San Diego County. Other than some patchy
stratus near the San Diego County coast early this morning...skies
are expected to be mostly clear through Saturday. Some patchy
stratus may return near the coast late Saturday night into early
Sunday with a slow increase in coverage and inland extent through
next week.

Inland high temperatures will continue to warm for Sunday through
early next week. This will push high temperatures to 5 to 10
degrees above average...around 105 in the lower deserts and in
the lower to mid 90s in the upper deserts. Slow cooling is
expected for the latter half of next week.

The Inland Valleys are expected to warm slightly on Sunday...then
cool next week as the marine layer slowly deepens and the cooling
towards the coast spreads slowly inland.

cig at KSAN between 12-16Z.


No hazardous marine weather is expected through Tuesday.
