As the weather shifts over Southern California, NWS San Diego forecasters are predicting cooler temperatures and possible showers toward the end of this week. According to the National Weather Service, today's temperatures for coastal areas range between 68 to 73 degrees, while residents in the high desert can expect highs of 84 to 88 degrees. The cooling trend is set to continue into Thursday and Friday, with this period seeing mountain temperatures drop as much as 10 to 15 degrees below average.
The upcoming change is due to a low-pressure system moving in from the northwest, which is forecast to affect the area late Thursday into early Friday. The chance of showers will mostly be light, a cooling trend that will also bring gusty west winds for the deserts onto the desert slopes of the mountains with gusts ranging from 25 to 35 mph and isolated gusts in the northern Coachella Valley below the San Gorgonio Pass could reach 45 to 55 mph, this weather situation could prove challenging for those unprepared for sudden gusts and cooler temperatures.
For those navigating through the coastal areas and valleys, an expected marine layer with low clouds and fog to consider could significantly reduce visibility in the mornings. The area forecast discussion released by the NWS San Diego detailed that the marine layer had deepened to around 2500 feet, with low clouds moving inland across many of the valleys and likely to persist into Thursday morning.
By the weekend, the low-pressure system is predicted to begin moving east, which will kick off a warming trend into early next week, leading into Tuesday's high temperatures near average at the coast to around 5 degrees above average inland. This shift could make for pleasant, warmer conditions, particularly for those longing for the cooler days behind. In aviation news, pilots are advised to expect mostly clear skies with unrestricted visibility today and tonight. Still, those at sea should note that while no hazardous condition is expected, occasional northwest wind gusts may exceed 20 knots late Thursday in the outer waters.
