|Imperial County Weather Synopsis|
The holiday weekend looks to be sunny with high temperatures into the mid70s and lows into the mid-50 to 40s. Light winds from the north to northwest will prevail across the county.
SYNOPSIS FROM THE SAN DIEGO OFFICE
High pressure aloft near the West Coast will bring dry weather with a warming trend through the weekend. Weak onshore flow will become weak offshore. There will be areas of low clouds and locally dense fog near portions of the San Diego County coast early this morning with patchy radiational fog extending into the valleys. Weak offshore flow will bring gusty northeast winds near coastal foothills and below passes and canyons for late tonight into Saturday with gusts to around 40 mph with weaker winds for Saturday night and Sunday. Weak onshore flow will return on Monday then strengthen for the middle and latter part of next week as a trough of low pressure moves inland through California Thursday night and Friday bringing strong gusty west winds in the mountains and deserts and a chance of precipitation.
SYNOPSIS FROM THE PHOENIX OFFICE
A pleasant holiday weekend is in store for the region. High pressure will build over the western U.S. into next week, keeping very cold air confined to east of the Rockies. Above normal temperatures and dry conditions will continue for the next several days. Some increase in winds are possible by the middle of next week, before a stronger storm system affects the Pacific Coast late next week.
