The San Diego region is in for a notable shift in weather patterns in the coming days. According to NWS San Diego, we can anticipate a slight warming trend starting today, with highs near normal across the forecast area. As we head into the weekend, residents and visitors should prepare for warmer days ahead, with temperatures on Saturday expected to climb a few degrees above normal.
Continuing the upward trajectory, Sunday promises a significant increase in heat, especially in the low deserts with highs nearing a scorching 110°F. The weather service warns that the peak of this heatwave will occur early next week, when areas within the Inland Empire could experience highs near 95°F, while some desert localities may see that mercury exceeds 110°F.
Furthermore, a separate discussion by the National Weather Service San Diego revealed that a deep marine layer is present this morning with some patchy drizzle, but that is expected to become shallow over the weekend into early next week. "For Tuesday, there is a 15-20% chance of high temperatures of 100 degrees or more in the far inland portions of the Inland Empire, and a 25-50% chance in the lower elevation portions of the high desert," the discussion noted.
However, some reprieve is anticipated by mid-week. The upper-level high responsible for the sweltering conditions is expected to weaken on Wednesday. Subsequently, as we get closer to Thursday and Friday, an upper trough is predicted to develop along the West Coast, ushering in cooler temperatures and a deepening marine layer. It's a forecast that surely will be a welcome change for many after several days of persistent heat.
No hazardous conditions related to this weather pattern are currently anticipated through Tuesday for aviation and marine impacts. Patchy drizzle might bring periodic visibility restrictions, but significant disruptions are not expected. Mountain and desert areas will largely remain clear, with some scattered cumulus predicted over northern regions.
