Easterly winds off the ocean helped keep temperatures subdued today, with many spots reaching the mid-60s or close to that for highs. After yesterday’s near 90 readings it actually felt a little cool despite the humidity. The next 24 hours is relatively quiet on the weather front, but wet times are ahead to close the work week.

Through Tonight: We stay rather socked in with clouds overnight, plus it remains cool and clammy. There could be an isolated to scattered shower or rumble, especially through the evening. But given we didn’t warm up much today, instability for such is quite lacking. Lows are mostly in the low-to-mid 60s. Watch out for some patchy fog and drizzle by morning.

Tomorrow (Thursday): Overall, the day is fairly cloudy, but we may see extended breaks particularly in the midday hours. With south winds kicking in a bit stronger, temperatures should try to warm up a little compared to today. So, maybe mid-70s to near 80 for highs. Much of the day should be dry, but a band of concentrated heavier rain should approach from the west and southwest heading into evening.

Pollen update: Tree pollen is high at 362 grains per cubic meter of air. Grass pollen is also high, with weed and mold spores low to moderate.

Southwest burning: Red flag warnings are up across southern California as very hot weather descends on the area through Friday. Highs today around Los Angeles were expected to reach the 95-103 range. Add in Santa Ana winds gusting past 50 mph and low humidity, and there’s quite the fire risk. A number are now burning in and around San Diego in particular, with impacts being felt at places like Camp Pendleton.
