DAKOTAS AND NEBRASKA — The Dakotas and Nebraska are the primary severe weather target Tuesday June 9th as a trough rolling off the northern Rockies fires supercells along a dryline into a 70-degree dewpoint air mass by late afternoon. The SPC Day 1 outlook updated at 9:15 AM shows a Level 3 Enhanced Risk red zone centered over the Dakotas and Nebraska, surrounded by a Level 2 orange zone extending broadly through the central plains and upper Midwest.
This is a long-duration event running well into the overnight hours, making phone alerts critical through the entire night.
