Discussion
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...
At 11 AM, the pressure gradient from San Diego to Tonopah, NV was running 5.6 mb offshore. Winds had come down from their peak with only place with wind gusts over 30 mph was directly below the Cajon Pass. Earlier today gusts to 45 mph were observed near the Cajon Pass. Weak offshore flow will continue into Sunday, becoming weakly onshore by Monday. Given the unsettled weather quickly turning to offshore flow, marine layer low clouds and fog will be absent from the coast this weekend. It's possible low clouds could return to some locations Monday morning, with higher confidence for low clouds returning by Tuesday morning.
High temperatures on Sunday are expected to be 3 to 5 degrees warmer than today with another degree or two of warming expected on Monday. By Monday, high temperatures in coastal areas will be 5 to 10 degrees above average, with temperatures closer to average further inland. Temperatures will begin to trend below average by the end of the week.
Global ensembles are indicating the potential for unsettled weather for the end of next week. There remains a lot of spread in solutions and uncertainty in the details. Rain chances are in the forecast as early as Friday. In addition to precipitation, cooler, cloudier, and windier conditions may develop. Please be prepared for more wet weather impacts, especially as you start to make those Halloween weekend plans.
