... 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 Utah... central Utah and southwest Wyoming on Sunday and Labor Day... dropping snow levels as low as 8000 ft. Some accumulating snow can be expected above this elevation across the higher terrain of northern Utah. As this system moves east of the region by Tuesday morning... 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.
