The center of an intensifying low pressure system continues to track eastward across the northern Plains and Upper Midwest this afternoon, bringing the threat of severe weather and isolated flash flooding to much of the region. On the warm side of the system, building instability combined with vigorous dynamics will likely lead to an outbreak of severe thunderstorms heading into the evening hours. The Storm Prediction Center maintains a Moderate Risk (level 4/5) of severe weather over portions of Minnesota, Wisconsin, and Iowa where strong tornadoes, very large hail, and damaging winds are expected. Severe weather is also possible farther south as well, and an Enhanced Risk (level 3/5) and a Slight Risk (level 2/5) surrounds the Moderate Risk and extends from the Upper Midwest to portions of the southern Plains ahead of a trailing cold front.

During the course of the next couple of days, most of the active weather associated with our ongoing Spring weather pattern is forecast to impact the mid-section of the country. A deep upper-level trough exiting the Rockies is currently interacting with a cold airmass dipping south from Canada into the northern High Plains. This interaction is leading to the formation of a low pressure system over the northern Plains. With additional lift provided by terrain interactions, the higher elevation of southern Montana is expected to receive additional snowfall today while the lower elevations in close proximity remain under the threat of flash flooding due to the prospect of additional rainfall and snowmelt in the vicinity. The threat of flooding is expected to diminish by later today as the m
