Hurricane Isaias is expected to make landfall along the U.S. northern Gulf Coast late Friday or early Saturday. A life-threatening storm surge is expected along the coast with damaging wind gusts extending well inland. Areas of heavy rainfall are forecast throughout much of the Southeast U.S. The remnants of Rachel will bring gusty winds and heavy rainfall to the Southwest U.S. this weekend. Read More >
Overview
March 13-14, 2019, a powerful winter storm brought heavy snow and strong winds to northeastern Wyoming and western South Dakota. Snow amounts across the area varied widely, ranging from around an inch across northwestern SD and the downsloped Newcastle area, to 16 inches in the central Black Hills, and 18 inches near Kadoka. Wind gusts reached 60 to 70 mph, which created a blizzard. Less than one quarter-mile visibility was reported across the area and drifts several feet deep resulted, even in areas that received only a few inches of snow. Below is the radar imagery of the storm. As you can see, there was a hole in the snow around Rapid City for a while, depicting the pocket of dry air Wednesday morning that kept snow at bay for several hours. This resulted in lowered snow amounts for Rapid City and the surrounding areas. Nonetheless, travel was hazardous to impossible due to the icing and drifting on roads and zero visibility.
Snowfall
Given the very strong winds that occurred with this blizzard, these snowfall totals are very preliminary.
