San Diegans looking for respite from the hot summer will be greeted with clear skies and near-average temperatures this weekend. Those hoping for rain might find small solace, with minimal chances for showers and thunderstorms mainly relegated to the region's mountainous areas. There's a slight change in the weather expected next week as the area welcomes a cooling trend with breezy conditions and a deeper marine layer rolling in, as reported by the National Weather Service San Diego.
The forecast suggests the city will experience a marginal increase in temperature today compared to Saturday, due to a strengthening of the upper-level ridge. However, this will be short-lived. Today, the National Weather Service indicates a "20% chance" storms could develop, particularly in the mountains of San Diego and Riverside counties. These could unleash rainfall rates of about "0.3-0.4" per hour."
As Monday approaches, a northwesterly flow ahead of an incoming trough will shift the after effects of monsoon moisture eastward, curtailing shower opportunities and lowering temperatures slightly as the ridge weakens. And while San Franciscans might be accustomed to the ebb and flow of our weather, those in Southern California should prepare for a notable cooldown midweek. Officials anticipate highs from 5 to 15 degrees below average starting Tuesday, a stark departure from typical September warmth.
The mercury will drop, and windier conditions will take hold, particularly "for the mountains/mountain passes and high deserts." Gusts ranging from "near 25-35 mph" are expected throughout the deserts, while regions like the San Gorgonio Pass could encounter gusts peaking at "45-55 mph." Toward the end of the week, the trough responsible for the unsettled conditions is expected to weaken and shift north, letting winds ease and temperatures rise toward their seasonal norms, per the National Weather Service.
Mariners aren't left out of the advisory loop, though little worry is required on their part. According to the National Weather Service San Diego, "No hazardous marine conditions are expected through Wednesday." So, it seems the sea provides the steadiness the land momentarily lacks, offering a bit of normalcy amid the winds of change sweeping through inland and coastal regions alike.
