Bay Area Poised for Midweek Heat Surge After Cool Marine Layer

Onshore breezes will hold coastal temperatures in the 70s until a high-pressure ridge drives inland highs into the upper 90s by Thursday.

The ridge of high pressure will be strong but will fall short of setting records. 
Temperatures will remain a bit below average Monday, with a warmup looming later in the week.
Sunny and seasonable conditions are on tap for Monday, but triple digit high temperatures return to the Valley Thursday.

Overview

  • A deep marine layer will persist through Tuesday, producing widespread overnight stratus, coastal drizzle and below-average temperatures.
  • High pressure shifting in from the Four Corners region Wednesday will spark a warming trend across interior Northern California.
  • By Thursday and Friday, moderate heat risk is forecast as interior areas including the East Bay Hills and San Joaquin Valley reach upper 90s to low 100s.
  • Onshore breezes will keep coastal and bay zones in the 70s and 80s, shielding them from the worst of the inland heat.
  • Uncertainty in late-week temperature projections stems from split model guidance, and smoke drifting from the Madre Fire could briefly degrade air quality.
