Weather Service: Wind, rain and snow through the weekend
The unseasonably warm weather in the Eastern Sierra and western Nevada the past week has changed as a strong cold front approaches the region, according to the National Weather Service in Reno.
A surge of Pacific moisture ahead of this front and ahead of a strong jet stream has moved into the area, according to a weather statement issued by the weather service. Showers will spread east this morning, mainly north of Interstate 80. Snow levels will drop to lake level by this morning. Only light snow accumulations are expected above 7,000 feet through this morning.
Windy conditions will also develop early today and increase through the day as the front nears. Wind gusts up to 50 mph are likely in the central Sierra and western Nevada, with gusts up to 60 mph possible in wind prone areas. Wind gusts over the Sierra ridges are forecast to increase to 80 mph today. Winds will diminish tonight and Friday as the front pushes south.
Snow levels will drop to all valley floors by Friday as the cold front moves through the area. A cold and unstable airmass will remain in place Friday and Saturday bringing periods of light to moderate snow or snow showers. snow accumulations will vary across the Sierra due to the showery nature of the snow.
However some areas above 7,000 feet may see 6 to 12 inches new snow from today through Sunday. High temperatures on the valley floors will drop into the 50s today and Friday and into the 40s over the weekend, while temperatures in the Sierra will remain in the 30s.
