The risk for severe storms will is expected to ramp back up over the weekend across portions of the Plains after several days of severe weather chances during the middle of the week.
On Friday, strong mid-level winds are expected to spread over the Southern Plains and Ozark Plateau around a weak trough moving out of the Southwest. Moderate to strong instability is expected to build during the day, which should support some organized severe storm activity.
Storms could be ongoing Friday morning as they drift southeast from the High Plains, with potential to re-intensify during the day. The dryline in West Texas and Oklahoma may serve as a separate trigger for thunderstorms which could turn severe as they move eastward. The Storm Predication Center (SPC) is highlighted the chance for isolated supercells that could grow into clusters of storms capable of producing large hail and damaging downdraft winds.
On Saturday, strong mid-level winds will move into the High Plains around a large trough of low pressure moving through the Northwest and Great Basin. Sufficient moisture is expected to return due to good southerly flow at the lower-levels which should promote moderate to strong instability in the region during peak-heating hours.
The Storm Prediction Center has outlined a risked area across much of Nebraska and South Dakota for the chance of severe storms with large hail the main threat as storms initiate. However, the SPC also has highlighted the potential for organized lines of strong storms, expected to move southeastward into the evening or perhaps overnight. If storms become organized in this fashion, the risk for widespread damaging downdraft winds is expected.
As a cold front from this system pushes farther south and east on Sunday, the threat for severe weather may expand as well.
