:: Storm Report
A very intense storm system that brought snow to the MT Rockies ejected across the Dakotas today. As the surface low spun over South Dakota and the upper level low rotated over eastern Montana, warm moist southerly flow increased across IA and southern MN. This primed the atmosphere for the development of several lines of thunderstorms. As each short-wave impulse of low pressure shot out of the surface low, the storms progressed from southwest to northeast. Rain began in earnest around the Twin Cities by 1100 and continued through the afternoon. After a break in the late afternoon and early evening hours, lines of storms redeveloped over SW MN. The line which contained a few supercells produced tornadoes across southern MN with some minor damage and no injuries. That line decreased in intensity as it moved across the Twin Cities, but nonetheless brought strong winds and some brief heavy rain. Although no severe thunderstorms were reported in the Lakeville area, it is possible that some residents experienced minor water ponding and some small-branch downings from these storms. No hail was reported with these storms in the Lakeville area. 0.52" of rain fell.
