Minimum relative humidity to dip below 20% in the Sierra Nevada, Foothills, Kern County mountains, and Mojave Desert.
A significant pattern change early this week will deliver not only rain and high elevation snow, but also many days with high temperatures struggling into the 70s. Quite a change from the warmth of this past weekend.
A strong storm diving south from the Pacific NW will stall just off shore of Southern California. Tropical moisture from the remnants of Trudy will then be pulled northward. Rain with embedded thunderstorms training over the same areas for several hours can lead to flooding in the very vulnerable cities and towns of east Kern county and the high Sierra of Tulare county.
