Weekly Highlights April 13th to 18th

This week’s weather pattern across the United States is shaping up to be active and, at times, hazardous, with multiple regions experiencing a variety of impactful conditions. Severe weather is expected to break out across Minnesota and into northern Wisconsin on Monday. Heavy rainfall, large hail, and gusty winds will be possible throughout the day. Atmospheric conditions may also support isolated tornado development, making this a situation that residents should monitor closely. Meanwhile, showers will develop across the Four Corners region to start the work week. From Tuesday through Thursday, and again on Saturday, a broad swath from the Midwest into the Plains and parts of Texas is expected to see repeated rounds of severe weather. These storms may produce all hazards, including damaging winds, hail, and tornadoes. In addition, heavy rainfall could lead to localized flooding concerns, particularly in areas that experience multiple rounds of storms. The Northeast will not be immune to the unsettled pattern, as remnants of these systems move eastward. Expect periods of showers along with isolated thunderstorms throughout the week.

In the western United States, snow is forecast in the higher elevations of the Rockies. Many areas are likely to see over four inches of accumulation, contributing to late-season mountain snowpack. Attention then turns to Saturday, when another system is expected to move through the Plains into the Great Lakes. This system will bring an additional threat of severe weather to the region. On the backside of the system, colder air may allow for snow to develop across portions of the Northern Plains into the Upper Great Lakes, with accumulations generally ranging from one to four inches.

Also on Saturday, the Southeast is expected to see another round of showers and thunderstorms, continuing the active weather trend across much of the country. This week, a contrast in temperatures will become more noticeable nationwide. The central to eastern portions of the United States is expected to experience mild and pleasant conditions. In contrast, the western United States will trend cooler.
