Temperatures across the San Diego region are playing it by the book, sticking close to seasonal averages but preparing to turn up the heat as the weekend approaches. According to NWS San Diego, Wednesday's highs were nothing to write home about, hovering around the typical time of year. But the mercury will rise Thursday, setting the stage for a significantly warmer Friday, with temperatures nearing or surpassing the usual marks.
The warming trend can be credited to an area of high pressure to the south. "High pressure to the south began a warming trend on Tuesday that will continue into the weekend," noted the Area Forecast Discussion by the National Weather Service. This upsurge in temperature means you can expect highs into the 80s and lower 90s for the Inland Empire, with the mercury pushing a sizzling 102 to 106 in the lower deserts today. While the coast enjoys a relatively mild 70-degree embrace, inland areas should be prepared for a little extra sizzle in their step.
Thursday will bring a shallower marine layer, diving to depths of just 1500 to 2000 feet, leaving night and morning coastal low clouds to creep into the western valleys. The weekend isn't shy to add a few extra degrees, particularly Sunday, with desert regions poised to leap an ambitious five degrees above the norm, sending thermometers in the lower deserts climbing between a sweltering 108 to 112 degrees, the Area Forecast Discussion elucidates.
As for the skies above, "clear skies with unrestricted VIS through Thursday morning," ensures the NWS San Diego in their aviation outlook. Mariners can also breathe easily; the waters are predicted to be serene, and no hazardous marine conditions are expected through Sunday. Indeed, with all this talk of heat and clarity, we find ourselves squarely in the embrace of a definitively San Diego summer.
