Blizzard Conditions Ahead for Sierra Nevada

A weak low-pressure trough moved into north-central California on Friday, April 10, bringing light and scattered precipitation to the region. However, a significantly stronger winter storm is quickly approaching. This next system is currently tracking south from the Gulf of Alaska and is expected to arrive in California on Saturday, April 11 (see image below).

Widespread rain is expected across much of California this weekend, particularly along coastal areas. Rainfall totals will remain relatively light—generally a fraction of an inch per day—but still enough to create slick road conditions and disrupt outdoor plans.

At higher elevations, particularly in the Sierra Nevada Mountains, precipitation will fall as snow. Periods of moderate to heavy snowfall are likely, especially in well-known mountain areas such as Mammoth Mountain and the Lake Tahoe region.

As the system pushes inland, snow chances will steadily increase through the day Saturday, becoming more widespread by the evening and overnight hours. Snowfall intensity is expected to build, with the heaviest accumulation occurring late Saturday into Sunday, April 12. Total snow accumulations could reach up to a foot in some locations, with isolated areas potentially seeing up to two feet. Conditions are expected to improve late Sunday, with clearing skies and calmer weather developing by Monday, April 13.

For those planning to head to the mountains, wind will be a major factor to consider.

In addition to the snowfall, breezy to occasionally strong winds are expected across much of the Sierra Nevada through Saturday and Sunday. Wind gusts may reach 35 to 45+ mph at times, creating difficult conditions in exposed areas and potentially affecting ski lift operations.

Temperatures will also drop significantly, with lows falling into the low 20s. Combined with gusty winds, wind chill values will make conditions feel much colder—especially at higher elevations and on ski lifts.

Looking ahead, the most favorable window for skiing appears to be Monday and Tuesday (April 13–14). By then, fresh snow will be in place, skies will be clearing, and winds are expected to subside. Additionally, lighter crowds are likely due to the workweek and late-season conditions.
