URGENT UPDATE: San Diego County is experiencing an unseasonably warm start to November, with temperatures expected to soar 8-12 degrees above seasonal averages today. This warm weather is attributed to upper-level ridging and offshore flow, making for a toasty welcome into the new month.
The National Weather Service (NWS) in San Diego warns visitors from the desert to the coast to brace for temperatures that exceed typical November readings. As of today, November 1, 2023, maximum temperatures will push into the high 70s and low 80s, offering a stark contrast to the usual fall chill.
For those venturing out this evening or early tomorrow, patches of fog are anticipated along the coast and in far western valleys, which may impact visibility. The NWS also predicts a minor cooling trend as onshore flow returns tomorrow, with a trough of low pressure moving in to provide some relief from the heat. Residents are advised to keep light jackets handy as temperatures dip slightly.
As the week progresses, a weak cut-off low is expected to slide over Southern California, bringing scattered high clouds by Sunday. This weather shift may offer picturesque sunset views, as sunset arrives an hour earlier this year.
The NWS reports that while the week will largely maintain a tranquil weather pattern, two short waves to the north that were previously expected to bring rain have diminished in strength. “Best we can possibly do is some marine layer drizzle Thursday morning, but even that is looking less likely,” the NWS stated.
Additionally, westerly winds are forecasted to increase across high regions and deserts by Wednesday and Thursday, while the marine layer may deepen, impacting coastal weather conditions.
In aviation news, coastal and western valley airports faced low clouds earlier today, causing visibility issues. However, VFR (Visual Flight Rules) conditions are expected to persist in inland areas, ensuring safer travel for air traffic.
For beachgoers and sailors, the marine scene remains free of hazards through Wednesday, though some higher-than-average surf will be seen along southwest-facing beaches today through Sunday.
Stay tuned for more updates as San Diego County navigates this warm start to November.
