A slow moving storm system currently in the Upper Plains will be a strong weather maker in the midwest the week. As a strong upper level wind strengthens today, it will cause a fairly high dose of severe weather, especially in North Dakota. The primary threat being large hail, and gusty winds. The storm will then continue to slowly move east and drag cold air with it. The cold air will be along a front that will interact with warm air rushing north to cause more severe weather in the midwest. Again large hail is the main threat.
