As Southern California gears up for another weekend, the weather forecast predicts a sharp spike in temperature that may lead to new record highs. According to NWS San Diego, temperatures are expected to rise "a few degrees warmer than Tuesday for lower elevations to as much as 15 to 20 degrees warmer for the Inland Empire." Coastal areas can expect highs ranging from 65 to 70, while the inland valleys may see temperatures between 70 and 78 degrees.

For those with plans this Saturday, brace yourself for heat as the lower deserts are forecasted to hit 104 to 108 degrees highs. The National Weather Service has outlined that Saturday's conditions will show "as much as 35 degrees warmer for inland areas than this past Sunday." The expected rise in temperature is "as much as 15 to 20 degrees above average for the inland valleys," with heat impacts most likely for the lower deserts, valleys, and inland Orange County.

Heat isn't the only weather-related event on the horizon. A change is coming early next week with a low-pressure system moving near the West Coast, prompting a noticeable cooling trend. High temperatures on Tuesday are predicted "as much as 10 to 15 degrees below average for the mountains, Inland Empire, and high desert," as reported by the Area Forecast Discussion from National Weather Service San Diego. Coastal areas will see daytime highs in the lower to mid-60s, while the Inland Empire can expect mid-60s to lower 70s.

Aside from the soaring thermometer readings, the National Weather Service notes that "there could be several record warm minimum temperature records for the date tied or broken with at least a few record warm maximum temperature records tied or broken as well." Residents and visitors should stay hydrated and cool as they navigate through the temperature surge while keeping an eye on the forecast for the anticipated cooldown early next week.
