Cedar City, Utah

... Becoming wet and unseasonably cool during the upcoming Holiday
weekend...

A moist and unseasonably cool Pacific storm system will move into
the Great Basin during the latter half of the upcoming Holiday
weekend. Widespread showers and thunderstorms can be expected
beginning Saturday afternoon across southern Utah... as monsoonal
moisture spreads northward into the area. This moisture will
continue north Saturday night... and encompass all of Utah and
southwest Wyoming by early Sunday.

As the Pacific storm system interacts with this moisture... showers
and thunderstorms are expected to become fairly widespread across
the region by Sunday. Some of these storms may become strong at
times... and be capable of producing locally heavy rainfall.

Much cooler air will filter into northern and central Utah... along
with southwest Wyoming during Labor Day... dropping snow levels to
near 10000 feet. Some accumulating snow can be expected above this
elevation across the higher terrain of northern Utah. As this
system moves east of the region Monday night... clear skies may
allow temperatures to fall below freezing across some northern
Utah valleys.

Those planning outdoor activities across northern Utah during the
upcoming Labor Day weekend are strongly encouraged to monitor the
weather... and be prepared for wet conditions beginning
Sunday... as well as much cooler temperatures by Labor
Day... particularly across the higher terrain.

Anyone planning outdoor activities across southern
Utah... particularly locations prone to flash flooding such as
slot canyons and Slick Rock areas... should be aware that the
threat for flash flooding will be elevated throughout the weekend.
Be prepared to take action should flash flooding develop.
