The storm system that previously affected the Western U.S. is now moving eastward, increasing the likelihood of thunderstorms from the Mountain West to the Plains states. Today, areas including Utah, Nevada, Colorado, and Wyoming will experience rain and intermittent thunderstorms. By the early part of the week, these storms are expected to shift towards the central Plains and the Mid-South region. The development of these scattered storms is supported by an increase in moisture and the approach of a low-pressure system.
