A slow-moving front extending across the midsection of the country will continue to be the focus for rounds of strong to severe thunderstorms across the Midwest through this evening. Meanwhile, the recent cool spell across the eastern U.S. will give way to heat over the next couple of days. The increasing warmth will help trigger scattered showers and thunderstorms across the lower Great Lakes and the interior Northeast today into tonight as a cold front approaches. In the meantime, an upper trough moving into the Pacific Northwest is forecast to deepen over the Intermountain West during the next couple of days. This weather pattern will bring progressively colder air with high elevation snow/mixed precipiation across the interior Northwest and then into the Great Basin for the remainder of the weekend. By Sunday night into Monday, the upper trough is forecast to deepen further, along with an expanding and deepening low pressure system over the central High Plains. This setup will help develop wet snow across the mountains of Wyoming, the Front Range and the Wasatch early on Monday. In addition, winds will become gusty as the low pressure system deepens. On the milder side of the system, organized clusters of strong to severe thunderstorms are forecast to impact the northern Plains to the upper Midwest mainly from Saturday night through Sunday. The Storm Prediction Center has issued an enhanced risk of severe thunderstorms from eastern Nebraska to southwestern Minnesota and southeastern South Dakota on Sunday to early Monday. Under an upper-level ridge, above normal temperatures will continue for central and eastern U.S. through the remainder of the weekend with highs climbing into the 90s in the interior section by Sunday. The hottest locations will be over the central Plains where highs topping the century mark is forecast. By Monday, below normal temperatures across the northwest will reach into the northern High Plains as spring snowfall unfolds across higher elevations of the northern to central Rockies.
