Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >
Overview
|
A strong spring storm brought abundant moisture and strong winds to the Black Hills region on April 6-8, 2024. As the storm moved into the area, strong winds in excess of 50 mph were common over northeastern Wyoming and southwestern South Dakota. A 58 mph wind gust was reported seven miles west of Ardmore, SD. Throughout the storm, gusty winds created blowing and drifting snow over a large portion of northeastern WY, which closed roads and made travel difficult. Snowfall amounts around a foot were reported over the higher Black Hills and Campbell County, WY. The heavy, wet snow was very elevation-dependent, with snowfall totals in Spearfish ranging from an inch or two to over 8 inches. Even in Box Elder and New Underwood, some residents woke up to over four inches of snow covering the ground, while the Rapid City area only had a little snow accumulation. Over two inches of rain and snow liquid equivalent were reported in the Black Hills and eastern foothills. At the NWS office in Rapid City, 1.98 inches of precipitation was reported, with only a trace of snow. |
