Southern California is riding a thermal rollercoaster, starting with a warming trend slated to peak tomorrow. The National Weather Service in San Diego forecasts high pressure and weak offshore flow that will push temperatures higher into the weekend, particularly heating things in the mountains and deserts by Sunday. Coastal regions, however, can expect a slight cooldown beginning on Sunday.
Residents in Orange and San Bernardino Counties should brace for "locally gusty north winds this morning along and below the coastal slopes," with gusts potentially hitting around 40 mph; the warmth is set to continue into the early part of next week, yet, as per the detailed discussion by the NWS San Diego, starting from Monday, a gradual decrease in temperatures will commence as a low pressure system moves into view, affecting the region through Wednesday and this system might usher in a notable drop on the thermostat, though any hopes for significant rainfall may be dashed with the chances slimming to less than 10 percent.
For those keeping track of the numbers, Saturday's high temperatures are forecasted "to be a few to around 5 degrees above average for the coast and valleys, with the mountains and deserts a few degrees below average," and let's not forget the lower deserts, which could become quite toasty with highs nudging toward 90 degrees, as stated by the NWS. On the flip side, by the time Wednesday rolls around, those same locales might feel a chill with temperatures possibly plunging to 5 to 10 degrees below the seasonal norms, heralding a slightly brisker range from the mid to upper 60s near the coast to the 70s in the Inland Empire.
Mariners and aviation enthusiasts, however, can breathe easy for now, with no notable marine hazards or aviation concerns on the radar through the early part of next week. The Skywarn network, a program encouraging volunteer weather spotters to report significant conditions, hasn't been activated, but with the dynamic shifts in the weather forecast, observers will likely stay vigilant.
