KEY MESSAGES

* Light rain showers continue along and north of Interstate 80 into the afternoon with a low chance of thunderstorms.

* Gusty winds will pose impacts to holiday travel and recreation today and Sunday.

* Below normal temperatures, breezy afternoon winds, and low shower chances are favored next week.

DISCUSSION

* A band of light showers that stretches from Lake Tahoe northward into Plumas and southeastern Lassen counties, and then eastward into central Washoe County will persist into the mid-afternoon. Any additional rainfall totals today will be light, and generally under 0.10 inch. There remains a slight 10-20% chance of thunderstorms this afternoon associated with the aforementioned band of precipitation, and those storms will still capable of infrequent lightning and wind gusts to 40 mph. But it's been too cloudy to get any sufficient instability. * Temperatures today are struggling to get into the mid-60s in the greater Reno area and low-70s in the inner basin. We are still sitting in the mid-40s to low 50s for most Sierra locations, and even upper 30s on the highest ridges. These readings are between 15 to 25 degrees below average for the first week of September. Widespread freezing temperatures are likely (80%) for eastern Sierra valleys and northeast CA tonight, and 40s for a majority of western NV. Winds are calming this afternoon and will continue to decrease tonight.

* For Saturday, we'll dry out and keep the calm winds. But by Sunday, another upper low pressure will swing through the region. This will once again ramp up gusty winds in the afternoon and allow for the shower and thunderstorm chances to return. Highest rain probabilities (40-60%) on Sunday are from northern Lassen County to the Oregon border, with a 10-20% chance of thunderstorms in the afternoon. These same areas have between a 30-60% chance for at least 0.10 inches of rain, but most areas on Sunday will be dry.

* A long-wave eastern Pacific trough pattern will persist into the middle of next week. This will keep us under cooler than normal temperatures, breezy afternoons, and low 20% shower chances. As for late next week, there remains high uncertainty into the remnant tropical moisture moving north into the region. At this time, there remains phasing and timing differences between the ensembles in the upper air pattern. -McKellar

AVIATION

Light rain showers may periodically lower CIGS/VIS to MVFR conditions at KTRK-KTVL through this afternoon. A few showers may still pass over KRNO through 00Z, but chances are low. Low clouds will lead to mountain obscuration at all terminals today and for Sierra terminals on Saturday. There are also low chances for fog in KTRK on Saturday morning. -McKellar
