Mountain snow and valley showers this weekend, windy Sunday to Monday – YubaNet


Mostly dry and calm until the end of the week. Another chance of widespread rain in the valley and snow in the mountains this weekend, followed by windy to windy conditions.


A high pressure ridge builds briefly to bring the return of warmer dry temperatures for today. On Thursday, the flow over the Pacific begins to become more zonal with a mostly dry weak short wave moving into the northern part of the forecast area. There could be enough humidity to produce flurries or drizzle on the higher elevations and increased cloud cover should help cool temperatures down a bit.

The weekday ridge returns for Friday ahead of an expected storm system this weekend. A thunderstorm system will move over the region on Saturday. This one will be much colder than the current one but of a similar nature in terms of precipitation to the one we have just had.

Snow levels are expected to start around 5500 feet and drop Saturday evening to around 3500 to 4500 feet. It’s not a big system, but it looks like it will at least bring some rain to the area. Right now it looks like the valley could receive between a quarter inch and a half inch of rain with the foothills and mountains between a half inch and an inch of rain. The station levels could receive between 4 and 8 inches of snow. After the front, we may be able to see thunderstorms in the area.

In-Depth Discussion (Sunday to Wednesday)

A ridge will form over the area behind the system for the first part of next week causing dry and warm temperatures to return. As the ridge builds the first part of next week, temperatures will warm to around 10 to 15 degrees above seasonal normals by Tuesday and Wednesday.

The main impact from Saturday evening to Sunday will be the increase in winds and becoming windy to windy in the region. Winds appear to be getting stronger Monday for the region as a jet moves over Nevada.

As the jet gradually moves east the winds will ease, but at this point windy conditions look possible through Tuesday before easing Wednesday.
