California saw record high temperatures over the weekend. Temperatures were around 15 degrees above normal. Here is a look at some of the numbers from this past Saturday:

MAP: Southwest Heat Index Contours

Bob Hope Airport: High- 92, Record- 96
Camarillo/ Oxnard: High- 94, Record- 85
Los Angeles: High- 94, Record- 97
Long Beach: High- 95, Record- 91
Santa Barbara: High- 89, Record- 88
Anaheim: High- 96, Record- 89
Sacramento: High- 87, Record- 87
Oakland: High- 87, Record- 86

Sunday also featured highs in the 90s for many locations. High pressure in the upper levels of the atmosphere combined with a light offshore flow allowed for this heat. California isn’t the only location seeing warmer than normal temperatures. The graphic below is the jet stream from Sunday; you will notice the large ridge in the west allowing for warm air to flow all the way to the Canadian border. The intermountain west is experiencing temperatures in the 70s, while the eastern half of the country is dealing with cold temperatures. Freeze watches are issued for residents as far south as the Gulf Coast.

A pattern change in the atmosphere will allow for a big cool down in California. Many valley and costal areas could see a 30-degree temperature drop through mid-week. An onshore flow is expected to increase and noticeably cooler temperatures will be felt across the region by Tuesday.
