A rare winter storm impacting the Southern U.S. will move offshore Wednesday morning. Behind the storm, arctic air will continue encompassing the eastern two-thirds of the Nation with only a slow return to normal temperatures expected by the end of the week. Moderate to strong Santa Ana winds and low humidity will maintain Critical fire weather conditions in southern California into Thursday. Read More >
Overview
Numerous thunderstorms developed in a very favorable environment during the early evening across northern South Dakota on Friday, July 21st. These storms moved southeastward over the course of the night, all the while producing torrential downpours with rainfall amounts over 2" in some cases, as well as severe weather in the form of damaging winds and large hail. Spink County was hit especially hard when a supercell produced up to 80 mph winds in and around Redfield and Tulare.Photos:
Several impressive storm clouds with broad rotation at times were spotted across the area

Radar, Satellite and Environment:
|
The storm environment featured hot temperatures and a very humid atmosphere. This allowed for explosive development of storms given the right trigger, which came in the form of several boundaries that were evident on radar during the early afternoon. Just right conditions developed by mid to late afternoon for storms to begin firing. The environment featured a large amount of instability; however the storm mode was determined mainly by the winds aloft. Winds in the low levels were rather weak, generally out of the south, while winds at 8000ft and higher featured westerly, unidirectional shear. The resulting storm mode was supercellular, with a tendency for cells to split. Splitting supercells are not uncommon; however, with the number and longevity of the storms that developed across the area resulted in a number of storm mergers. Strong storms that merge can result in a brief intensification. This is what occurred just before the storms hit the Redfield and Tulare areas, and as that storm collapsed it generated upwards of 80mph wind gusts and significant storm damage. |
