While April has been known to have some pretty good storms here and there, this will be one of the strongest we’ve had in some time. A very wet atmospheric river is moving into the region bringing high winds (a Wind Advisory is up for western Nevada through Friday), heavy valley rain (A Flood Watch is up into Saturday Morning) and deep mountain snow (a Winter Storm Warning for the mountains runs through Saturday afternoon.) The main storm Friday will come in two waves, the first late Thursday night into Friday morning, and the second coming late Friday. Strong southwest winds will create some shadowing, but significant spillover will occur, especially on the west side of the valley.
Travel over the passes will be very difficult Friday, with high winds and heavy snow creating whiteout conditions. Snow levels will drop below the lake sometime during Friday, although they can bounce up and down a bit.
Colder air moves in behind the main storm front, and snow could fall all the way to the valley floor by Saturday.
Conditions do dry out on Sunday and temperatures will rebound from the 40s on Saturday back into the 50s on Sunday.
