The San Diego region is expected to experience cooler temperatures and possible rain showers today, according to the National Weather Service San Diego. A forecast published on their website reported that the remnants of Tropical Storm Juliette will bring more clouds and lower high temperatures across the area, making the region's southern and eastern parts more likely to receive measurable rainfall.
There's a slight chance to see some thunderstorms this afternoon, possibly, the National Weather Service notes. For residents in the higher elevations, such as the Riverside and San Bernardino Mountains, these thunderstorms could become severe enough to induce isolated flash flooding, especially if there are breaks in the overcast skies. The forecast also suggests that we are looking at high temperatures 10 to 15 degrees below average, with coastal regions experiencing mid-70s to lower-80s, and the lower deserts getting up to the lower 90s.
Moving into the weekend, conditions are expected to dry out and warm up, with temperatures on Saturday remaining a few degrees below average. The National Weather Service's Area Forecast Discussion from the National Weather Service predicts mid-70s to low 80s near the coast and 104 to 108 degrees for the lower deserts. Sunday should see temperatures within a few degrees of average for most areas.
Looking toward next week, forecasters are predicting an increase in monsoonal moisture, which could lead to chances of afternoon showers and thunderstorms in the mountains and deserts between Tuesday and Thursday. These could range from 20 to 30 percent likelihood. In terms of marine conditions, there is also a slight chance of thunderstorms this afternoon, which could cause abrupt winds and create rough seas, along with potential lightning and hail, the discussion indicates.
Although not specifically requested for activation, the NWS has encouraged weather spotters in the region to report any significant conditions they encounter throughout this weather event.
