The National Weather Service San Diego has forecasted temperature highs for various regions in Southern California. On Sunday, coastal areas are expected to see mid-70s to low 80s, while valleys might experience higher temperatures ranging from upper 80s to mid-90s. The Inland Empire could heat up with temperatures spanning the upper 90s to 102 degrees, with mountains staying cooler in the 80s. The high desert might reach sweltering highs from the upper 90s to 105 degrees, and the low desert is predicted to be between 100 to 108 degrees, as per the information available on their website.
Monday's forecast continues the warm trend but should offer slight relief. Coastal areas will experience mid to upper 70s, valleys will have upper 80s to low 90s, and the Inland Empire is anticipated to have mid to upper 90s. Mountain regions will remain in the 80s, high desert areas will cool slightly to the upper 90s to 100 degrees, while the low desert stays above 100 with a high forecast of 105-110 degrees.
An area forecast discussion from the NWS provides further insight into the weather patterns. A statement suggests that it is "Slightly cooler today with continued chances of thunderstorms
over the mountains and deserts." While Monday will see lower thunderstorm chances limited to the mountains, the rest of the week is expected to have near normal temperatures with patchier morning clouds and fog at the coast.
The forecast discussion also warns of potential thunderstorms this afternoon and early evening, with chances increasing to around 25-40% for the mountains and 20-25% for the deserts. Residents and visitors in these areas should be prepared for "locally heavy rain, gusty winds, and lightning." In the marine areas, no hazardous conditions are expected through Wednesday, providing some respite for seafarers and leisure boaters alike.
The NWS encourages weather spotters to remain alert and report significant weather conditions, although "Skywarn activation is not requested at this time but may be needed this afternoon." As the week progresses, Southern Californians will likely welcome the reprieve from the intense heat, with the temperatures easing closer to seasonal norms and the marine layer gradually thickening along the coast.
