Very unique setup shaping up for Friday morning. We’re looking at a very high-sheared environment and a racing line of thunderstorms Friday morning. HRRR model runs show the 50 MPH winds affecting NW AL at 8:00 AM, and the line of storms quickly following. There remains abundant uncertainty regarding the severity in the line of storms, but high confidence in the wind given the setup.
