.DISCUSSION...

Today is the last in a series of warm, spring-like days before a
distinct weather pattern change ushers in a period of stormy and
much cooler weather over the weekend. The culprit behind the sudden
weather change is a deepening upper low that traverses across the
western states over the weekend but stays south of the region. As
the upper low passes, it`ll bring periods of mountain snow and
valley rain, increased chances of thunderstorms, breezy winds, and
unseasonably cooler temperatures/hard freezes.

Mountain snow showers begin as early as Friday afternoon before
heavier snow arrives during the overnight hours into Saturday AM.
This is the period (late Friday night through Saturday morning) when
most of the snow will fall in the Sierra, White Mountains, and
mountains of southern Lyon and Mineral counties, and thus is when
travel disruptions are most likely. Given that it`s late April and
roadways are warm following several days of spring warmth, it`ll be
very difficult for snow to accumulate on roads during the daytime. A
few heavier snow/pellet showers may be able to provide light
accumulations locally Saturday afternoon. Snow showers will wrap
up Sunday morning, bringing snow totals to 1-3" for lower Sierra
communities (e.g., Truckee, South Lake), 3-6" along Sierra passes
and Mammoth Lakes, and up to 8-12" along highest peaks of the
Sierra, White Mountains, and S. Lyon/Mineral County mountains.
Elsewhere, a dusting to an inch may result in minor travel impacts
for foothill areas above 5500 feet (Virginia City). It`s a good
idea to get any weekend traveling done today or Friday AM, or be
prepared for slick roads and delays if you must travel this
weekend.

Lower western Nevada valleys will likely see periods of light rain
over the weekend with 10-20% chance of isolated thunderstorms Friday
and Saturday afternoons. Strongest thunderstorms will be capable of
brief heavy downpours, gusty outflows, and occasional lightning.
It`ll also be noticeably cooler this weekend, especially on Saturday
when daytime highs only reach the 40s and 50s. Temperatures will
approach freezing Saturday night, so be sure to protect sensitive
vegetation. We`ll warm up and dry out in earnest early next week
with showers and thunderstorms possibly returning by midweek.
