Winter storms from the Pacific Ocean bring rain to thirsty hills and valleys and drop snow on mountaintops, which later melts and provides an additional burst of needed moisture. A winter storm dumped massive amounts of precipitation across southern California this weekend, including more than 6.5 feet of snow to Mountain High and more than 5 inches of rain to Cucamonga . Discovery Company. This is a negative PNA phase, and it creates an environment where low-pressure systems help pull in storms from the Pacific toward California. These atmospheric ingredients will also be present to generate some early-season snow, but this will not be an indicator of how the entire winter will play out, but instead, the start of a bookend winter in terms of snowfall. Despite the weather pattern shaping up in a similar matter as it has the past two years, Pastelok warns that this winter "will be a little different from last year, as far as the primary storm track across the West Coast.".
