As temperatures stabilize throughout the week in the San Diego area, the National Weather Service forecasts minimal change day-by-day. San Diego County sees the lower 70s near the coast and mid-80s to lower 90s inland today, followed by similar temperatures tomorrow, according to the National Weather Service San Diego, CA. The Inland Empire will experience the mid-80s to mid-90s, while the high deserts hover around the 90s to lower 100s, and the lower deserts scorch at 104 to 110 degrees. Residents in the mountains at elevations from 4500 to 7000 feet will enjoy cooler temperatures in the 70s to mid-80s.
With bated breath, waiting for a reprieve will do little good, as it seems the slow warming trend is intentional, commencing on Wednesday and spilling over into the weekend. Coastal areas could find some solace with patchy night and morning low clouds providing intermittent cover, purported by the National Weather Service San Diego CA Area Forecast Discussion. Meanwhile, the inland empire sees temperatures incrementally climbing, with high temperatures in the mid-90s to 105 by next weekend.
While the coast basks in relaxed conditions, the latter part of the week forecasts a surge in temperature paired with humidity on the rise. Alongside the warming trend, "There is a 15 to 25 percent chance for thunderstorms for the mountains into the deserts each afternoon for Friday into next week," as noted by the National Weather Service. Coupling these conditions inevitably increases monsoonal moisture, bringing back the chance of afternoon showers and thunderstorms, thus painting a sticky and unpredictable weather tableau for the region.
This means that for public safety and comfort, it may be time to brace for the heat, as the rise in temperatures holds the potential for an excessive heat warning for deserts starting Friday through at least Monday. For those hiding out in the valleys and mountains, Heat Advisories may become a reality, warns NWS. Residents and visitors alike should mark their calendars and plan accordingly, ensuring a steady supply of water and shade to weather the desert's wrath boasting between 110 to 116 degrees.
San Diego International Airport and other coastal transportation hubs are not without their challenges, as aviation reports mention a 60-70 percent chance for ceiling impacts in the morning from low clouds, which have been playing a shy game, forming slower and with less density than previous nights. While the marine conditions seem calm through Friday, the weather above, it would seem, has its turbulent plans for those both airborne and grounded.
