Northern California weather: October sees rare heat wave

Fall and October begin with continued heat and fire risk.

SACRAMENTO, Calif. — Northern California just experienced its hottest summer on record, but the hits keep coming.

So far, there have been 45 days with temperatures 100 degrees or hotter in Sacramento, but there could be a few more that would extend that record.

Tuesday will get close to records for the region.

The coastal range and Bay Area will see widespread 100-degree temperatures in the valley and 100+ temperatures. San Francisco could top 92 degrees which would be the hottest day in two years. For the foothills, upper 90s will be the forecast and 80s for the Sierra.  

Since this is so hot for October, it's worth looking at records. Here are some numbers of note:
