Bay Area to See Sunny Skies After Rainfall

The Bay Area is transitioning back to warmer, sunnier weather following a two-day period of light rain. A storm system moving down from the Gulf of Alaska brought steady, though light, rainfall overnight, with temperatures dipping into the mid-40s.

Rainfall Totals Across the Region

The National Weather Service (NWS) reported that the rain is expected to cease completely by Thursday morning. Rainfall totals varied across the region, with Mount Tamalpais in Marin County receiving the most at 1.6 inches from Tuesday through Thursday morning.

Regional Rainfall Measurements:

  • Ben Lemond & Mt. Umunhum (Santa Cruz County): 1.5 inches
  • Downtown San Francisco: 0.5 inches
  • Oakland: 0.3 inches
  • San Jose: 0.1 inches
  • Walnut Creek: 0.05 inches

Warm Temperatures Expected This Weekend

Following the rain, high pressure will rebuild, bringing warmer temperatures. While not as intense as the record-breaking heat experienced in March, temperatures are forecast to reach up to 80 degrees in the hottest areas by the weekend.

Oakland and parts of the Peninsula may see temperatures around 75 degrees, while San Francisco could reach 70 degrees. “We’re going to dry out and get some sunshine,” said NWS meteorologist Rick Canepa. “There will also be some breezy gusty wind.”

Offshore Winds and Potential for Future Precipitation

The expected winds are predicted to blow from the ocean, helping to maintain warmer overnight temperatures and contribute to the building heat. However, a developing lower-pressure trough could limit the duration of the warm spell.

The weather service notes that this trough may also bring more precipitation next week, though it is currently too early to confirm. The recent rainfall was brought by two low-pressure systems, one originating from the Central Coast and the other from the Alaskan Gulf, marking the first measurable rain in the Bay Area since March 2nd.
