URGENT UPDATE: San Diego County is experiencing a surprising heat wave as November kicks off, with temperatures soaring 8-12 degrees above seasonal norms. The National Weather Service (NWS) San Diego reports that visitors from the desert to the coast can expect unseasonably warm conditions today, transforming the start of the month into a warm welcome.
The current warm spell is attributed to upper-level ridging and offshore flow, although gusts are expected to remain mild, reaching around 25 mph. Residents should prepare for the possibility of fog blanketing coastal areas and far western valleys as night falls.
Looking ahead, the NWS forecasts a shift in weather patterns, with minor cooling expected as onshore flow returns tomorrow. A trough of low pressure will begin influencing the region, prompting locals to keep a light jacket at hand.
As the week progresses, a weak cut-off low pressure system off the Southern California coast is projected to bring scattered high clouds, potentially enhancing the sunset’s colors. The NWS indicates this weather system will mostly be a transient visitor, with minimal impact on the overall warmth of the week.
Despite initial predictions for mid-week showers, the outlook has shifted, with the NWS suggesting that the best chance for moisture might only yield marine layer drizzle Thursday morning. Winds are expected to pick up across high regions and deserts, while the marine layer may deepen, contributing to the region’s unique coastal climate.
For those planning air travel, low clouds have impacted visibility at coastal and western valley airports, with conditions dropping to just a few miles earlier today. However, Visual Flight Rules (VFR) conditions are anticipated to prevail in inland areas, ensuring smoother travels.
Beachgoers and sailors can expect calm marine conditions through Wednesday, though some elevated surf may create larger waves along southwest-facing beaches from today through Sunday.
This developing situation signals a notable change in weather patterns for San Diego County. Stay tuned for further updates as temperatures fluctuate and new systems move into the area.
