Residents across inland valleys and lower coastal mountain slopes in San Diego can expect the thermometer to climb even higher today, as forecasters at the NWS San Diego predict further warming trends. This rise in temperatures is part of a pattern that’s set to peak by Monday, with inland areas bracing to hit highs up to 15 degrees above the seasonal norm. The warm spell is not forecast to break at least until the middle of next week, when a cooling trend is anticipated to begin, bringing down temperatures to near or slightly above average.
Due to a strengthening ridge combined with offshore flows, the temperatures on Monday are projected to possibly reach the low 90s for inland valleys and the lower deserts, while coastal areas may experience the upper 70s to low 80s. As reported by the Area Forecast Discussion from the National Weather Service San Diego, “The ridge will also make the marine layer much shallower, confining the low clouds and fog to the immediate coastal areas.” However, an incoming trough and a closed upper low developing far off the coast could eventually merge to cool down conditions significantly
Wind conditions are also on the NWS San Diego’s radar, with weak to moderate Santa Ana winds expected on Sunday. Forecasters have specifically warned of locally gusty Santa Ana winds along coastal mountain slopes and in the passes and canyons. The strongest gusts, “when gusts of 30-40 mph are expected in the favored locations,” may occur on Sunday, as noted in NWS San Diego’s discussion…
