Issued at 142 PM PST Tue Feb 3 2026 (This evening through Wednesday) High pressure remains firmly in control of the synoptic pattern over the Western United States today. This has resulted in mostly clear skies throughout the majority of the San Francisco and Monterey Bay regions. Lingering Tule Fog is evident on GOES-West imagery this early afternoon, confined to portions of far interior Contra Costa County along the Delta. Most communities will wrap the day up with about 2 to 5 deg F of warming compared to Monday. Exception to this will be the interior East Bay. For Wednesday, several locations will be within a few degrees of daily records for February 4. Official forecast for San Jose Airport tomorrow is 74 deg F (record is 76 deg F), Salinas Airport 79 deg F (record of 80 deg F), and Monterey Airport 77 deg F (record of 77 deg F). && .LONG TERM... Issued at 142 PM PST Tue Feb 3 2026 (Wednesday night through next Monday) Pleasant and dry conditions will continue through the work week before the West Coast ridge gets undercut by a weak upper-level low off SoCal and Baja California. This will promote the beginning of a cooling trend around Friday that will last into the weekend. By late weekend and into next week, ensemble guidance advertises the arrival of a progressive longwave trough to the West Coast, introducing something we haven't seen in a several weeks: rain. There has been a gradual delay with onset of rain chances. Previous forecast packages have noted arrival of rain as soon as early Sunday morning for coastal Sonoma and evening for the Central Coast. The NBM has continued this onset delay with the slight chance of rain now scheduled to arrive to the North Bay closer to mid-day Sunday and the Central Coast late evening Sunday (i.e., pushed back by ~6 hours). Still, the total rainfall amounts appear to remain very light at this time. Some breezy winds may be associated with this system on Monday. && .AVIATION...
