San Diegans are bracing for a shift in weather conditions as forecasters predict cooler temperatures and rain showers across the region. According to the National Weather Service San Diego, today will see a slight dip in temperatures compared to Wednesday, with highs ranging from 70 near the coast to the mid-70s in the valleys and the mid-50s to upper 60s in mountain areas of the Inland Empire.
However, things are set to change quickly as a low-pressure system deepens the marine layer, introducing a cooling trend that will persist through Friday. The NWS San Diego has projected the potential to bring island band showers to the region starting late into the night, with a slight chance of thunderstorms forecasted as well. Coastal areas can expect scattered showers and cooler temperatures, with inland valleys and the high desert experiencing temperatures around 15 degrees below average.
The week's end will bring moisture and a slight chance to disrupt outdoor activities. On Friday, NWS San Diego mentioned "showers and a slight chance of a thunderstorm from the Inland Empire to the high desert" in a social media post. This weekend's warming trend suggests that temperatures in the Inland Empire will reach the upper 80s to mid-90s on Sunday, potentially climbing to the 90s for the early days of the following week.

Marine conditions are expected to remain unremarkable, with no hazardous conditions projected for Monday. As the communities in Southern California prepare for the incoming weather, no Skywarn activation has been requested, but spotters are nonetheless encouraged to report any significant conditions.
