Severe weather continues to be a threat across the Plains today (Friday). A slight risk for severe thunderstorms extends from near Lake Michigan to the Rio Grand River in Texas. Damaging wind gusts and large hail are the biggest concerns. There is a threat for isolated tornadoes, stretching from areas in West Texas through the Great Lakes.   Strong instability will build ahead of a cold front, providing robust updraft to support severe storms. High humidity and warm temperatures will provide fuel to keep storms firing. Showers and thunderstorms will develop along a warm front and ahead of a cold front in the afternoon. Storms will become more numerous in the early evening and continue through the night. Coverage is not expected to be as widespread or strong as earlier this week, but a few storms may become rather intense. For WeatherNation: Meteorologist Mace Michaels
