Record high temperatures were broken in Vista and Oceanside Harbor Wednesday as Santa Ana winds pushed hot and dry weather into San Diego County, the NWS said.
An area of high pressure is giving San Diego County its offshore flow, bringing Santa Ana winds to the region.
"Through the afternoon, It's going to be warm -- the hottest day of the week," NBC 7 Meteorologist Sheena Parveen said. "We could see record highs."

Record high temperatures were reached at the Oceanside Harbor with 84 degrees and Vista at 89 degrees, the NWS said.
Temperatures were expected Wednesday in the mid-80s at the coast, about 90s degrees inland, in the mid-60s for the mountains and nearly 90 in the deserts.
The winds have also prompted a wind advisory for the mountains and inland areas until 2 p.m. Tuesday.
During that time, winds could produce gusts up to 50 mph. Gustiest winds will occur in the morning before dying out a bit in the late afternoon, Parveen said.
The high-pressure system bringing Santa Ana winds to San Diego County is expected to weaken by the weekend, bringing cooler temperatures and a chance for rain by early next week, Parveen said.
