SYNOPSIS FROM THE SAN DIEGO OFFICE
Dry and warmer weather will continue through Wednesday. There will be periods of gusty Santa Ana winds with gusts mostly 45 mph or less into Wednesday morning. A low pressure system moving inland through California on Thursday will bring stronger onshore flow with cooling gusty west winds in the mountains and deserts and
more clouds. For Friday through next weekend stronger high pressure aloft near the West Coast and surface pressure over the Great Basin will bring a greater warming trend. There will periods of mostly weak and gusty Santa Ana winds near the coastal foothills at times.

SYNOPSIS FROM THE PHOENIX OFFICE
After a cool start this morning, temperatures will quickly recover this afternoon with highs warming each day through Thursday.

A warming trend is forecast over the weekend and into early next week as a ridge gradually builds over our area.
