Pleasant weather for northern California today as we cooled down a few degrees to return to a more seasonal level for the end of May. Don’t get used to it, though … weather changes, including a lot of heat, are coming soon. We had a pleasant cooling of a few degrees today as a low pressure trough moved rapidly over our region. A few clouds will move overhead tonight, but it will be a pleasant night, and it should be ideal for seeing the total lunar eclipse. The eclipse is total from 4:11 a.m. to 4:26 a.m., but will be partial from around 2:45 a.m. to around 5:50 a.m. The weather tonight will be generally clear and mild with lows from the 1930s in the mountains to the 1950s in the valley. Wednesday will be mostly sunny with highs from the 70s to the lower 90s.
A low pressure will move over Oregon on Thursday and Friday. We will miss most of its effects, but we will have some clouds, stronger breezes and a slight cooling of our highs. Another weak low may bring a slight risk of mountain showers on Saturday, but very little rain will fall. A much stronger ridge of high pressure will then push over California for the remainder of Memorial Day weekend, and it will bring many of the hottest temperatures we’ve had since last year. Nightly lows won’t cool down much due to our warming air mass, staying in the 50’s and 60’s in the valley until next week. Daytime highs in the valley will be well above average, ranging from the mid and high 80s to the lower 90s and 100s.
