Imperial County Weather Synopsis
SYNOPSIS FROM THE SAN DIEGO OFFICE
High pressure aloft well off the Southern California coast will bring slow warming through Thursday...weaker winds in the mountains and deserts...with the marine layer becoming shallower with few night and morning coastal low clouds. A low pressure system moving through the Great Basin will bring slight cooling for Friday and Saturday with gusty north to northwest winds for inland areas. Warming with weaker winds for Sunday and Monday with high pressure aloft off the California coast.
SYNOPSIS FROM THE PHOENIX OFFICE
A series of mainly dry weather disturbances from the Pacific will move through the western states through early next week. These systems will keep afternoon temperatures near or slightly below normal, along with providing for breezy to windy conditions. One stronger disturbance on Friday has the potential to produce a slight chance of afternoon showers over the eastern Arizona mountains.
Winds continue to be rather breezy to even windy in some locations early this morning. The strongest winds currently are focused across SE California where a few locations continue to see gusts above advisory level. Winds will remain breezy through the rest of the day across SE California, but fall below advisory level shortly after sunrise.
