Today was very much like yesterday. An onshore wind kept the air mass dominated by oceanic air. After a cloudy start, sunshine broke through, but clouds filled back in. These weather regimes are tricky when it comes to sky cover. As winds shift more toward the south, we’ll eventually lose the marine layer, but we’ll pick up warmer temperatures and more humidity in its wake.
Through tonight: The humidity is already on the way up, although it won’t get too high until we get nearer morning. That allows temperatures to drop off nicely this evening as the sun sets. It’s a good one for any outdoor activities as skies remain variably cloudy. Any clearing Friday evening may end up reversing late night as we keep an easterly flow going into early morning. Lows are mainly in the near 60 to mid-60s range.

Tomorrow (Saturday): We start transitioning away from the brilliant weather of the past two days, but it will be a slow process. The main difference here may be increased humidity. As winds slide around to the southeast around 5 to 10 mph, they help pump in higher dew points. But, it’s still near(ish) normal, with highs mainly around 80 to the low-80s. Skies will be variably cloudy — probably cloudiest early in the day and clearer for the rest of the time.
Sunday: This is definitely the least pleasant of the weekend days, unless perhaps you have pool plans. Skies are sunniest early, with clouds tending to increase during the midday and afternoon. A cold front approaching the region should spark off showers and storms late in the day as well. Before that, highs reach the mid-80s, perhaps upper 80s in spots. Showers and storms are likely during the evening, maybe lasting into the overnight.
Pollen update: Weed and grass pollen is HIGH. Mold spores are MODERATE. Tree pollen is LOW.
