SAN DIEGO — Light drizzle and cloud cover is being tracked this Friday morning, mainly west of the mountains. Into the remainder of the day, clouds will take longer to part but expect at least partial or filtered sunshine closer to noon and beyond. Temperatures will trend cooler than normal across all four microclimates today, mainly between 2 and 10 degrees below seasonal averages.
Here's a look at that patchy drizzle from satellite/radar imagery this morning, closer to 5:00 a.m. but mimicking a similar pattern through sunrise. Also notice how far east clouds stretch, essentially toward the mountains. Most of the county (excluding deserts) can expect an overcast, drizzly morning with a light breeze before conditions improve by afternoon.
Even into the weekend mornings, we will continue to see the cloud cover rolling in across the coastal basin. The combination of a developing coastal eddy and onshore flow will help deepen the marine layer through Saturday. The low clouds will bunch up along the coastal mountain slopes. Expect a chance for patchy drizzle on Friday and Saturday mornings.
Gusty winds will be felt throughout the county, but the strongest winds will be in the mountains and desert. Periods of breezy to strong westerly winds will continue through Saturday morning.
Expect gusts up to 45 mph and isolated gusts up to 50 mph. They will be strongest along the desert mountain slopes. This is why temperatures will take a hit tomorrow. Though strong, wind speeds look to fall short of the advisory criteria.
AT THE COAST THROUGH FRIDAY:
Surf heights will be 2 to 4 feet with sets up to 5 feet on Saturday. There will also be a moderate risk of rip currents present at our local beaches.
This weekend will be mild. By the start of next week, Monday and Tuesday will be a few degrees warmer inland as high pressure starts to move in. Those will be a transition days. Temperatures will peak above seasonal as high pressure strengthens over the Southwest by the middle of the week. Widespread 70s are expected along the coast with 80s inland and triple digit heat in the desert.
