Saturday will be mostly quiet with clouds increasing through the day, Highs will range from the low 40s to upper 50s with light W to SW winds of 5 MPH to 10 MPH. Lows overnight into Sunday morning will follow an West to East gradient as clouds keep temperatures warmer to the west, ranging from the lower 20s to upper 30s.
A quick moving upper trough passing through the Pacific Northwest will clip northern Nevada late Saturday evening through Sunday afternoon. Warming temperatures during the weekend mean that snow levels will be very high, above 8000 feet, and areas generally north of I-80 could see isolated light rain showers with accumulation of a trace to 0.15" possible.
High temperatures across northern and central Nevada Saturday afternoon will be around eight to fifteen degrees above normal for this time of year. Near record warmth is expected throughout central Nevada Saturday afternoon.
