An already-weird August, with record highs and lows, delivers a parting shot in the form of an intrusion of cool damp air, producing fog throughout the neighborhood. The overnight low was 45 degrees and we're on track to reach 90 degrees today.
Kingbird is in the bottomlands of the lower Cosumnes river watershed and receives cold drainage regularly, in all seasons. A nearby low spot saw an early-morning low of 39 degrees a few weeks ago, and that's not unique for August. In the winter, our lows are generally 5-8 degrees lower than the offical record for nearby communities. Annual incursions into the low 20s (or even high teens) are normal.
