Dangerous heat will persist across the Southwest U.S. through Friday with daytime highs of 110-115°F. Heat across the southern Plains will briefly ease to near-normal by late week before returning over much of the Plains into next week. Scattered strong to severe thunderstorms are possible across parts of the Northeast U.S. on Thursday. Damaging wind, hail, and a tornado or two are possible. Read More >
Overview
An intense low pressure system moved across the High Plains on October 12th, 2021. An "Enhanced" Risk of severe weather was forecast, as well as the potential for blowing dust and high winds before the storms formed later that evening. Initially, a few storms formed in extreme northwestern Kansas, but these storms were never able to fully mature into supercell thunderstorms. Eventually, a significant line of thunderstorms formed along the Kansas/Colorado border and moved east. It is this line of thunderstorms that produced the severe weather reports, with a tornado near Sharon Springs, wind damage near Oakley, and a few severe hailstones reported. In addition, beneficial rain fell as the majority of the area is experiencing drought conditions.Storm Survey Results:
