Significant Winter Storm to Impact the Western U.S into Tuesday; Critical Fire Weather Conditions Across the Southern High Plains

A strong winter storm will continue to progress into the Northern Rockies and Great Basin, bringing heavy mountain snow and strong winds through Tuesday. Heavy snow combined with strong winds will produce near-blizzard conditions, with snow rates of 1 to 2 inches per hour. Dry, gusty winds will create widespread critical fire weather conditions in the southern High Plains through Monday. Read More >

Overview

A large storm brought heavy rain and historic late season snowfall to the Black Hills region May 20-22, 2019. A powerful low pressure system slowly moved from the Four Corners region northward through the Plains during this time, leading to a prolonged period of precipitation to western South Dakota and northeastern Wyoming.

Precipitation type throughout the event was largely dependent on elevation. Locations on the plains north and east of Rapid City saw predominantly rain, while higher elevations in the foothills just to the west and south of Rapid City and the Black Hills received several inches, or even multiple feet, of snow.

For the Black Hills and western South Dakota plains, this three-day period was among the coldest, wettest, and snowiest stretches on record over the latter half of May, with several temperature and precipitation records set.
