SoCal is gearing up for a warm spell this week, as the National Weather Service forecasts a rise in temperatures across the region. According to the NWS Forecast Office in San Diego, coastal areas are expected to see a few degrees increase over Sunday's temperatures, with highs ranging from the lower to mid 60s, while inland valleys could experience the 70s and lower 80s.
As the weather patterns shift, Tuesday is predicted to be significantly warmer, especially for the inland valleys and lower coastal slopes of the mountains, "around 5 degrees warmer than Monday near the coast to 8 to 12 degrees warmer," per a statement obtained by the National Weather Service. The warming trend is due in part to high pressure aloft moving across southern California, which is also set to result in temperatures for the lower deserts reaching the mid 80s to lower 90s.
By Wednesday, the deserts are anticipated to get a few degrees warmer than Tuesday, though the coast and valleys are not expected to see much change, maintaining highs in the mid to upper 60s and lower 80s respectively. The Apple and Lucerne Valleys can brace for the mid 70s to lower 80s, while mountain areas from elevations 4500 to 7000 feet can look forward to the 60s and lower 70s.
However, this warm period isn't set to last, as a "weak low pressure system" is forecast to bring cooler temperatures by Thursday and Friday. "A little warmer for next weekend," the Area Forecast Discussion from the National Weather Service indicates, but with night and morning coastal low clouds and fog to likely deepen into the valleys.
For mariners, the immediate news is good, with no hazardous marine conditions expected through Friday, according to NWS marine updates. On land, the 7-day forecast from the weather.gov site suggests sunny days with gusty winds followed by evenings with the possibility of patchy fog. And Skywarn activation, a volunteer-based severe weather spotting program, has not been requested, though spotters continue to report significant weather conditions to the NWS.
