The coastal Carolinas may experience flash floods in the coming days due to repeated thunderstorms. Additionally, a wave of intense summer heat will hit the Southern Plains and central Gulf Coast States this week. Read More >
Overview
|
A large winter storm brought rain and dense, wet snow to the region Sunday March 14th through Monday March 15. The same system brought significant snowfall to the front range of the Rocky Mountains and severe weather to the Southern Plains. Precipitation started off as rain for many areas March 14th before gradually changing over to all snow by that night and then ending the morning of March 15th. Snow was heavy at times with snowfall rates between 1-2 inches observed in many areas. A daily record for rainfall was set at Sioux City and daily snowfall records were set at Sioux Falls and Huron during this event. |
