|Imperial County Weather Synopsis|
|SYNOPSIS FROM THE SAN DIEGO OFFICE
A low pressure system over the eastern Pacific will bring stronger onshore flow today with cooling spreading inland....a deeper marine layer with patchy drizzle in some coastal and western valley areas early this morning...and periods of gusty west winds in the mountains and deserts. Warming will follow for Wednesday through Saturday as high pressure aloft strengthens near the West Coast with weak offshore flow for Friday and Saturday. A return of onshore flow will bring a cooling trend for Sunday through early next week.
SYNOPSIS FROM THE PHOENIX OFFICE
High pressure will remain in control of the weather this week, lifting the storm track to our north. A series of Pacific weather disturbances will travel through the ridge flow, bringing periods of breezy conditions and passing high clouds. One stronger Pacific disturbance will cut through the Four Corners for the late week. Windy conditions and fire weather concerns may result with temperatures holding in the 90s across the lower elevations. Dry and even warmer conditions are forecast for the weekend as ridging strengthens further.
