It's largely a Ctrl+C, Ctrl+V kind of morning per GOES-West visible imagery with abundant sunshine for most Bay Area communities, with the exception in the Delta region and portions along San Pablo Bay shoreline with Tule Fog. Temperatures are generally running within a few degrees of where they were this time yesterday. Expect a repeat of well-above normal temperatures this afternoon along with a few communities within striking distance of daily record highs. Please refer to the climate section for details on record highs for the day. No forecast updates planned for the morning; things remain on track.

A strong ridge of high pressure and light offshore winds will bring warm temperatures and dry conditions once again to the area today. Most areas will see their warmest temperatures of this warm pattern today, reaching the upper 60s to mid 70s near the coast, and 70s to near 80 inland. A few spots will approach record high temperatures for the date with highs around 10 to as much as 20 degrees above normal. See the CLIMATE section below for relevant record high temperatures for today. Outside of areas of fog in the North and East Bay valleys, as well as the southern Salinas Valley this morning, skies will be mostly clear. Patchy fog will redevelop tonight in similar areas to this morning.

The upper level ridge bringing us warm and dry conditions will gradually move east on Thursday, allowing temperatures to cool a couple degrees from today. A weak cutoff low will then approach the coast and dive south off southern California and Baja California Friday and Saturday. This will usher in the beginning of a pattern change with temperatures cooling another 5 degrees or so and clouds increasing.
Confidence is high that a sustained pattern change will take place Sunday into early next week as a longwave trough sets up along the West Coast. However, confidence in the details (timing/strength) is lower. Rain chances will increase from the north through the day Sunday, generally reaching 10-30% across the greater SF Bay area by the afternoon and extending into the Central Coast by the evening. Our area is likely to be on the southern fringe of the trough, resulting in very light amounts from any rainfall with this initial activity.
Precipitation chances remain elevated Monday and Tuesday as the trough along the coast deepens, opening the door for additional systems to move through. The trend toward a deeper trough brings better potential for higher rainfall amounts, but totals are still favored to be light to moderate. This pattern will bring much cooler temperatures, dipping a few degrees below normal by early next week. Periods of breezy winds will also develop.
