An upper low will slowly track northeast and move onshore into northern California late this afternoon. Rain, with some embedded thunderstorms, will continue over much of northern California into portions of central California while extending through southern and central Oregon and into western Nevada. Scattered to numerous wet thunderstorms are expected across the greater Four Corners region, while isolated to scattered thunderstorms are likely across the Great Lakes, south Texas, and Florida Peninsula. Gusty east-northeast winds of 10-20 with gusts to 40 mph amid minimum relative humidity of 15-30% are likely from north-central Oregon into the Washington Cascades and Columbia Basin. Southerly sustained winds of 10-20 mph gusting 25-35 mph amid minimum relative humidity of 10-25% are expected across the southern and eastern halves of Nevada into western Utah, southeast California, southern Idaho, and far northwest Arizona. Relative humidity is likely to drop below 35% across much of the Southeast and below 25% on much of the southern and central Plains coinciding with well above normal temperatures.
