San Diego residents, brace yourselves for a thermometer-breaking weekend ahead. According to the National Weather Service San Diego, inland valleys are expected to experience high temperatures in the mid-80s to mid-90s, peaking for the lower deserts between a scorching 107 and 113 degrees by Friday. Coastal areas, though, can pull out their sweaters, with highs remaining around 70 degrees—an excellent contrast to the desert sizzle.
For those living or traveling through the mountains, be prepared to encounter temperatures slated to persist around 5 to 10 degrees above average. The forecast suggests the heat for the deserts will peak on Friday and Saturday. However, don't expect to continue to see the coastline shiver; a warming trend is on the horizon early next week, with temperatures poised to swing up another 5 to 10 degrees.
Extreme heat warnings have put the lower deserts on high alert, and an excessive blaze that the Area Forecast Discussion clarifies has been issued for the lower deserts for Friday and Saturday. With reports of widespread major heat risk and isolated extreme heat risk, residents are strongly advised to take precautions to ensure health and safety. As we dip into Sunday, a slight cooling is anticipated, only to potentially rebound again by Tuesday to levels similar to what residents have already endured.
Regarding aviation, coasts, and valleys encounter a blanket of low clouds with bases near 800-1100 feet MSL, affecting visibility and impacting flights early into the day. These conditions are expected to scatter later, with marine impacts not predicted to be harmful through Sunday. Whether it’s land or sea, staying updated on current weather conditions is critical for safety and planning throughout this period of fluctuating temperatures.
