...Cold air funnel this afternoon and evening...

The showers and thunderstorms across NV are capable of producing
cold air funnels this afternoon and evening. We have already
gotten several reports of cold air funnels which is indicative of
a favorable environment for formation. On rare occasions the
funnel can reach the ground and become a weak tornado that can
cause property damage and personal injury. Take the threat
seriously and seek shelter if you see a storm approaching.

...Showers and Thunderstorms Continue This Weekend...

Scattered showers and isolated thunderstorms will continue to
impact the eastern Sierra and western Nevada again this afternoon.
General chances for a thunderstorm will increase to around 25%
for any location for Sunday by this afternoon. When thunderstorms
develop there is potential for heavy rain, hail, dangerous
lightning, as well as gusty and erratic outflow winds. Wind gusts
of 35 to 55 mph will be possible near thunderstorms or moderately
developed cumulus clouds. At times these wind gusts can appear to
come out of nowhere. Thunderstorm development for today will
likely be delayed until after noon. There are indications that
some storms could be stronger today with potential for damaging
winds.

Some light snow or accumulating small hail is not out of the
question near and above 9000 feet in the Sierra. This could lead
to difficult travel over Sonora Pass, Ebbetts Pass, and along
Highway 120 west of Lee Vining.

Be sure to have a way to receive weather alerts if you have
outdoor plans. Be prepared for cooler temperatures, rain, and have
a plan to reach shelter should thunderstorms approach your
location. Those venturing into the backcountry should carry extra
gear, as thunderstorms and rainfall can result in hypothermia. We
have seen temperatures drop 30-40 degrees in heavier showers. If
you have outdoor activities or celebrations be prepared to secure
banners, signs, hats, and temporary structures as gusty winds can
loft these items rapidly. When it comes to lightning safety, there
is no safe place if you are caught outdoors during a thunderstorm.
Be sure you have a quick exit strategy to a sturdy building or
vehicle. Lightning may spark new fires as well, as we have seen
today, so be sure to quickly report any new smoke you notice.
