A slow moving front will be the focus area for heavy to excessive rainfall and a threat for flash/urban flooding across the northern Gulf Coast and Southeast U.S. through this weekend. Abnormally hot, potentially record-breaking, temperatures will impact southern California and stretch north toward the Bay Area and Central Valley into next week. Read More >
Overview
|
A large winter storm moved through the region on March 9, 2019, bringing a mix of precipitation and snow. As the main system moved northward into the region, precipitation started as freezing rain at many locations. Ice accumulations up to a tenth of an inch were reported. This resulted in hazardous travel conditions in the early morning hours. Precipitation changed over to rain through the morning, before transitioning over to all snow from west to east by midday. Moderate rain (including a record rainfall of 0.86 inches at the Sioux Falls Airport) and poor drainage due to snow on the ground, created ponding water and street flooding around the Sioux Falls metro area. Following the change to snow, gusty northwest winds caused drifting snow which iced over on several roads, prompting the closure of Interstate 90 west of Mitchell from Saturday evening until early Sunday morning. |
