KEY MESSAGES

Updated at 1252 AM PST Thu Feb 26 2026

- Warmer and drier conditions for the next few days

- Cooler conditions this upcoming weekend

SHORT TERM

Issued at 1203 PM PST Thu Feb 26 2026 (This evening through Friday)

Now that the low clouds and areas of dense fog are improving, expecting the warm up to persist across the region through the afternoon. Temperatures are forecast to be in the upper 60s to lower 70s across much of the North Bay and San Francisco Bay Area with interior areas of the Central Coast likely to warm into the upper 70s (cannot rule out a few of the warmest locations reaching or exceeding 80 deg F).

Tonight, we are expecting less widespread coverage of fog as the high pressure aloft continues to build and precipitable water values (PWAT) of 1"-1.15" shift northward across the North Bay. This is where we have the greatest potential for patchy fog early Friday morning. In addition, mid-to-high level clouds will increase throughout the night and linger into the upcoming weekend.

By Friday, forecast to be the warmest day across the region, temperatures will likely warm into the low-to-mid 70s across the North Bay, East Bay and San Francisco with the San Francisco Bayshore warming and the rest of the region warming into the mid-to- upper 70s. The greatest potential for areas to exceed 80 deg F is in the Santa Cruz Mountains and interior portions of the Central Coast. These temperatures are some 10-15 degrees F above average with the higher terrain up to 20 degrees.

LONG TERM

Issued at 1203 PM PST Thu Feb 26 2026 (Friday night through next Wednesday)

Temperatures cool slightly on Saturday, but only by a few degrees ahead of an approaching mid/upper level cut off low. The low pressure system will move into northern California and Oregon by Sunday evening and into early Monday morning. This will bring cooler, unsettled weather across the Bay Area and Central Coast. Afternoon temperatures both Sunday and Monday look to trend closer to seasonal averages. As far as precipitation goes, we are not expecting much rain at all from this system as probabilities remain very low for widespread rain. However, the North Bay and the coastal ranges look to have the greatest potential for for receiving rain from Sunday afternoon through Monday morning.

Confidence beyond Tuesday lessens, yet shortwave ridging across the region is expected to warm temperatures slightly. However, troughiness looks to return for the latter half of the upcoming week. However, widespread rainfall is not looking likely.
