Be Weather Aware this Weekend
The chances for strong to severe thunderstorms continue to remain in the forecast starting today and going into the holiday weekend.
Today: The primary focus areas for strong thunderstorms will be across western regions of South Dakota with the best chance over the northwest.
A shortwave ridge will move east today and enter the northern plains. A west to southwest flow at the mid-levels will become established. With this flow in place, thunderstorms are expected to develop this afternoon ahead of the shortwave across northern, Wyoming and southeast, Montana.
Storms will then move eastward and grow in size and in speed, which will bring increased chances of damaging thunderstorm winds threat to northwest, South Dakota. As these storms continued their track eastward into central and eastern, South Dakota overnight, the strength of the storms will decrease.
Saturday: Southwest mid-level flow continues over the region as a series of impulses move northeast into the upper Midwest. Forecast models are showing a trough or dryline over the upper Plains along with a disturbance moving into western Nebraska and into the southwest, South Dakota. Thunderstorms are once again to develop by the late afternoon and spread eastward through the overnight hours.
Sunday: This day looks to bring the highest risk of severe thunderstorms with the primary focus will be across eastern, South Dakota. Thunderstorm development looks to happen later in the afternoon/evening hours and continue through the overnight hours. All forms of severe weather is on the table along with tornado chances.
