Expect rainfall across the area this weekend especially from Saturday evening through the middle of the day Sunday. There is a marginal risk or at least a 5% chance of excessive rainfall through much of Kern County and along the Sierra Nevada mountains slopes.
The low that is currently over the PNW is going to push moisture into the Central Valley over the weekend! This'll make for a cloudy Halloween 🧛🎃 and a wet Sunday ☔. Here's the current probabilities of exceeding a quarter of an inch of rain (0.25"). It's a fast moving system, however. Come Monday, ridging will have taken place, hence the abrupt drop in rain chances.
Ooooh spoookyyy 👻. Whether you're out trick-or-treating, staying in, or handing out candy, you'll want to know what sort of tricks the weather may play! However, this forecast is nothing but treats 🍫🍬! The trough in place will strengthen and combine with a low to bring a chance of a wetting rain (0.10" or greater) Saturday night for those trick-or-treaters in the Foothills. Throughout the entire Valley, overnight lows are looking to be a range from the mid 40s to the low 50s. The number on the left hand side is the best case scenario (colder temps 🥶), while the number on the right is the worst case scenario (warmer temps 🥵).
