Forecast Valid From: Mar 8, 7:00 AM CDT — Mar 13, 7:00 AM CDT
To the west, an area of stronger instability is forecast across the Mid MO Valley, where northwesterly midlevel winds of 35 kt will exist along the southern periphery of a trough sweeping across the Upper Great Lakes. Evening/overnight storms may occur across parts of eastern NE, IA, and MO, and instability may be large enough to warrant at least low severe probabilities as the event nears in time.
