Loren says the North Bay city will hit the 90-degree mark Thursday. If it happens that will shatter the city's record high of 83 degrees.
Forecast models show a big ridge of high pressure moving toward the Bay Area and Loren says that ridge will be at its maximum strength on Thursday. She says there is a chance the ridge could stick and keep the region extra warm Friday as well.
Loren has the following high temps for Thursday:
- San Jose 82
- Concord/Livermore 82
- Napa 80s
- San Francisco 75
- Oakland 78
The warming trend will be short lived. Loren says even in the best case scenario, the ridge breaking down by Saturday.
