...much colder temperatures with snow returning late tonight and Tuesday...
Cold low pressure in the Gulf of Alaska will move into the west coast bringing an end to the recent period of mild weather. A cold front moving across eastern California and western Nevada is expected to bring moderate snow amounts to the Sierra late
tonight and Tuesday with lighter snow amounts possible in portions of western Nevada by Tuesday afternoon.
Southwest winds will increase this afternoon and evening with gusts up to 35 mph in the Lake Tahoe Basin. The strongest winds are expected Monday night and early Tuesday morning from Lake Tahoe southward across Mono County and in far western Nevada including Reno and Carson City. In these areas gusts up to 45 mph are possible with ridge gusts in the Sierra up to 100 mph.
Light snow will develop over northern Lassen County and the Surprise Valley by late tonight. A larger area of snow will develop over the Sierra on Tuesday with a period of moderate to locally heavy snow possible Tuesday afternoon through early evening. See winter weather advisories for additional snowfall information.
For lower elevations western Nevada, a shorter period of snow is possible Tuesday afternoon. More uncertainty exists for snowfall amounts, but some locations may receive up to 2 inches.
Temperatures on Tuesday will be 15 to 25 degrees colder compared to this past weekend. Highs will range from the upper 30s and lower 40s for most valleys with lower 30s in the Sierra Valleys including the Lake Tahoe Basin. Low temperatures Tuesday night will range from the mid teens to lower 20s for western Nevada - and from 5 to 15 degrees in the Sierra Valleys.
Anyone planning travel over the Sierra passes Tuesday through Wednesday morning should prepare for winter driving conditions with slick roads...chain restrictions and travel delays. For
western Nevada, bands of snow could produce slick roads and reduced visibility around the peak commute times Tuesday afternoon and evening.
