... 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. Showers and thunderstorms will begin Saturday afternoon over 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 this Pacific storm system approaches the area Sunday and interacts with this moisture... showers and thunderstorms are expected to become fairly widespread across the region. Some of these storms may become strong at times... and will be capable of producing heavy rainfall. The greatest moisture will be over southern Utah... where widespread rainfall totals of one to two inches are possible. This will result in an elevated risk of flash flooding over the Holiday weekend.
Much cooler air will filter into northern and central Utah... as well as southwest Wyoming on Labor Day... dropping snow levels as low as 8000 ft by early Monday evening. 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... clearing 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 on 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 Holiday weekend. Be prepared to take action should flash flooding develop.
