A fall heat wave is gripping San Diego county this week with most areas under either a heat advisory or warning as temperatures rise into summer-like territory five to 15 degrees above average for this time of year.
Thanks to a bit of high pressure, an offshore flow is warming San Diego County with a heat advisory for the coast and inland valleys through 8 p.m. Wednesday and an excessive heat warning for the deserts until 11 p.m. Tuesday.
Temperatures are expected to peak on Tuesday and be in the mid-80s at the coast and the mid-90s inland. The mountains will see temperatures near 90 degrees and the deserts could reach 110 degrees, NBC 7 Meteorologist Sheena Parveen said.

From Tuesday's peak, temperatures will gradually cool into the weekend as cooler airmass returns. It may even feel fall-like, Parveen said.
“It’s going to be unseasonably warm across the whole county,” NBC 7 Meteorologist Sheena Parveen said. “But the good news is as we head into the weekend, we’ll start to cool down a little bit.”
