an extended period of rain in the forecast?

That's almost unheard of! First, the temperatures. The past two days have been beautiful, almost fall-like, in Chico, with highs in the upper 70s both Tuesday and yesterday. Expect a warming trend beginning today, with highs in the mid 80s (still not bad for this time of year), and upper 80s for tomorrow, the first full day of summer. It will be fairly warm this weekend, with lower 90s on Saturday. However, a change in the weather pattern will begin Sunday, when a chance of rain (what?) will enter the picture, with highs only topping out in the mid 80s. That chance of rain will continue through Tuesday, as a plume of deep moisture from the Pacific moves east over Northern California. The National Weather Service is stating some rainfall records could be broken. But, one must put this statement in perspective: rainfall rates this time of year are very low; it wouldn't take much for those rainfall records to be broken. That said, you may need to retrieve that umbrella from storage when going to work on Monday and Tuesday. More details to follow as this forecast gets fine-tuned.
