Roads will probably be worse at night time as temperatures fall and the snow is ready to accumulate at a a lot faster charge. Visibility will probably be poor all through the storm as a consequence of blowing snow.

Snow totals will vary from six to 10 inches at lake stage, to over a foot within the High Sierra. Even the valley may see some mild snow early Sunday morning. The foothills of Reno may see as much as 4 inches, together with Virginia City, the North Valleys, and Galena. Carson City has a barely higher probability at seeing accumulating snow than Reno. Any snow that does fall will primarily accumulate on grassy areas and soften in a short time.

The odds of seeing at the least a couple of inches of snow at Donner is 90% and it’s a 50% probability of at the least seeing a foot. The snow will are available bursts, because the sample is convective with remoted thunder and lightning doable as effectively.

The ensembles of the GFS are exhibiting lesser quantities than the principle GFS mannequin. This tells me snow is probably going, with at the least a number of inches, and a foot is a fairly good wager as effectively. Two toes nonetheless, is much less sure.

The snow stage drops to 7,500’ by Friday night, and stays between 6,500’ and 6,800’ on Saturday earlier than dropping to the valley ground Sunday morning. Showers are nonetheless doable on Sunday as low travels east over

Reno. Moisture will probably be much less favorable by the second half of the weekend although. The snow would be the most intense Saturday night time. None to minimal impacts are anticipated in Reno and Carson City.
