Once again an Atmospheric River will sweep through the region, bringing more rain and flooding concerns to the region. Thursday morning showers will turn to significant rain below 8,500’ in the afternoon, and there are flood watches and warnings throughout the region. The biggest concern once again will be small streams and drainages, especially in the lower mountains and foothills. Minor to moderate flooding could occur on the Truckee River near the town of Truckee, while the rest of the river should peak just at or under flood stage. Other rivers with significant flooding concerns include the Feather, Susan and Pitt Rivers.

High winds will also accompany this storm system, with valley gusts expected as high as 70 mph and mountaintop speeds well above 100 mph. A High Wind Watch is now posted for Thursday, and there’s a good chance that will be upgraded to a High Wind Warning.

As the Atmospheric River drops down to the south late Thursday night, some cooler air will move into the region, dropping temperatures from the low 60s Thursday to the 50s Friday. Mountain snow showers should decrease Friday evening. As things dry out over the weekend, temperatures will fall back into the 40s.
