The National Weather Service in San Diego has issued a weather synopsis for the region from today through next Monday, hinting at a mildly tumultuous temperature journey. According to their latest discussion, coastal residents and inland valley dwellers should brace themselves for a persisting heat through Wednesday before a gradual cooling occurs from Thursday to Saturday. A slight uptick in warmth is forecasted for the following Sunday and Monday. The marine layer is also set to deepen, with night and morning coastal low clouds expected to march farther inland when nighttime falls over the western valleys.
In the short term, NWS San Diego forecasts little change in high temperatures until Wednesday. After that, folks in the area can look forward to a dip by a few degrees come Thursday. For the better part of this week, high temperatures will swing around 4 to 8 degrees above average in the deserts. At the same time, the western valleys and inland coastal areas could be a tad cooler, by around 5 degrees below average. Those buzzing about in the lower deserts will continue battling the sweltering heat, facing highs between 110 and 115 degrees Fahrenheit until the reprieve at week's end.
The latter half of the week will yield a more noticeable chill, as a weak low-pressure system lies over California. The NWS expects high temperatures to plummet below average by a few degrees in the deserts and by 8 to 12 degrees in the inland valleys. By Saturday, the mercury will be hovering around 70 near the coastline and scaling upwards to the 80s and around 90 for the Inland Empire. The deserts, however, will still grapple with 102 to 106 degrees, even as the cool-off begins.
