San Diegans bracing for a mix of cooler climes and potential showers this week, with the National Weather Service predicting a refreshing downturn from the recent heat. According to the NWS forecast, the inland valleys are experiencing slightly cooler temps today, while coastal areas see little change, coastal temperatures ranging from mid to upper 60s and mountain areas basking in the 60s and lower 70s.
However, a curveball may be thrown into this mild weather pattern. A "weak low pressure system moving inland across southern California for Tuesday night and Wednesday could bring a few light showers to the mountains for Wednesday afternoon," per the Area Forecast Discussion. With less than a 15 percent chance of measurable precipitation, the showers are fleeting and focus on elevated regions. Lower deserts look like they may sizzle with heat rising to around 100, and valleys and Apple and Lucerne Valleys stay comfortably in the 70s to upper 80s.
As the week progresses, the coastal low clouds are expected to continue their languid spread inland, with a slow dance of clearing anticipated at the beaches, as the Area Forecast Discussion. A slight warming trend may lift spirits and temperatures across most areas by Thursday and Friday, with desert highs projected to march up 5 to 10 degrees above the norm. Palm Springs may be touching the 105 mark by week's end, making it feel a little more like summer.
Yet, this warm spell won’t linger long, as a cooling trend is set to sweep in over the weekend, approaching normal temperatures for the desert regions and dropping a few to around 5 degrees below average for the coast and valleys, those looking to escape the heat will find some solace come Monday. While marine conditions remain benign through Friday, keeping sailors and beach-goers alike content, no Skywarn activation is requested, but spotters remain vigilant in recording any noteworthy meteorological shifts.
