|SYNOPSIS FROM THE SAN DIEGO OFFICE
Greatest warming today will be west of the mountains...with warming of 10 to 15 degrees in some western valley and inland coastal areas with high temperatures in those areas warming to around 90. The greater warming on Saturday will be for areas farther inland. High temperatures Saturday will mostly be 10 to 15 degrees above average...except 15 to 20 degrees above average in some of the inland valleys. This will push high temperatures to around 100 in the lower deserts...and into the lower 90s in the inland valleys...upper deserts...and far inland Orange County. Onshore flow will return on Sunday with several degrees of cooling for most areas with a few degrees of cooling in the lower deserts. Some patchy stratus may return near the coast late Saturday night into Sunday morning with some patchy stratus possible near the beaches Sunday afternoon.
SYNOPSIS FROM THE PHOENIX OFFICE
High pressure will remain in control of the weather this week, keeping the storm track to our north. Breezy conditions will affect the region today behind an exiting dry weather system and temperatures will hold in the 90s across the lower elevations. Dry and even warmer conditions are forecast for the weekend as highs will likely hit 100 across many desert locations. A gradual cooling trend is forecast to begin Monday and last through the middle of next week as high pressure weakens.
