According to my go-to weather prediction and history site, WeatherSpark.com, we did indeed drop below 32F last this morning around 5-6am. Luckily, it only remained below freezing for about about an hour.
A friend reported frost on their car this morning, so that seems to confirm that frost did hit, at least in certain areas of the San Fernando Valley. I am glad I covered my container plants last night. Tonight’s predictions are only around 34F, so we should be ok, but I will keep an eye on the temperature just to make sure we don’t lose anything.
