Sunday Sizzle Inland

High pressure will strengthen over Northern California to wrap up the weekend leading to temps climbing well into the 90s to near 100 inland across our valleys near the Delta, Tri-Valley and South Bay.Closer to the coast a moderate sea breeze and marine layer in the 500-1000 ft. range should keep the heat confined mainly in inland areas. Highs near San Francisco will be in the mid 70s to lower 80s with mid 80s for Oakland. San Jose south should see highs in the lower 90s to near 100. Sunday is also a Spare the Air day with the worst ground level ozone concentrations in the East Bay and Santa Clara valleys.Monday should be nearly as hot inland as a stronger sea breeze begins to develop by mid-afternoon. This will lead us into more significant inland cooling as a trough of low pressure to our north promotes more onshore, cooling winds through the middle and latter half of the week.Rob Mayeda
