...Cold Temperatures, Winds, and Snow Return This Week...

After a quiet holiday weekend, a few storms are on track to bring
back colder temperatures, periods of windy conditions, and the
potential for snow in the Sierra and western Nevada the week
ahead.

A quick-hitting storm will pass through the region Monday
afternoon and evening with gusty winds, colder temperatures, and
chances for snow. Highest snow potential will be for the Warner
mountains, Surprise Valley and northern Washoe County (60% chance
of 2-4 inches) with lesser potential as the storm slides
southward across the Interstate 80 corridor (50% chance of a
dusting). Snow is anticipated after the Monday evening commute,
but could bring localized slick roads overnight and into the
Tuesday morning commute.

Winds will be more impactful than the snow with this early week
storm. Widespread valley wind gusts 35 to 45 mph are forecast with
Sierra crest winds gusting 80+ mph. Plan on recreational impacts
for backcountry activities and for area lakes as well as
turbulence for aviators on Monday.

Later in the week simulations are honing in on a couple of
potentially more impactful storms. These stronger storms would
pack more of a wind and snow punch if they track into the Sierra
and western Nevada.
