The agency said that a ridge of high pressure anchoring over the Four Corners area — Arizona, Colorado, New Mexico and Utah — will begin to influence weather patterns in Southern California on Tuesday, elevating temperatures about 10 degrees above average for this time of year.
The ridge is expected to start pushing northeast by the end of the week, slackening its grip and giving way to low pressure troughs that will allow for a return to seasonable temperatures, forecasters said.

For the two or three days of high heat, the NWS reminded residents to "drink plenty of fluids, stay in an air-conditioned room and stay out of the sun" during peak temperatures.
"As the high moves to the east, the flow across the area will become southeasterly by early next week, opening the area to at least a gradual influx of monsoonal moisture by early next week," the Weather Service stated.
In the Coachella Valley Monday and Tuesday, highs will settle near 110, but on Wednesday and Thursday, they may top out around 115 or higher, with slight cooling going into the weekend. Lows will generally hover in the mid 80s all week long.
In Riverside metro, the daytime mercury will crest in the low 90s Monday and Tuesday, while on Wednesday and Thursday, highs will approach 100 degrees, with slight cooling for the weekend. Lows are expected to settle in the mid 60s all week.
