SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0745 PM CDT Thu Oct 08 2020 Valid 090100Z - 091200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF SOUTHERN LOUISIANA... ...SUMMARY... A tornado is possible over near-coastal southern Louisiana after midnight tonight. ...Southern Louisiana... According to the National Hurricane Center, Hurricane Delta will maintain major hurricane status and move through the northwestern Gulf of Mexico tonight. The outer rainbands of Delta are expected to move into the coastal sections of Louisiana after 06Z. RAP forecast soundings along the western and central coast of Louisiana gradually increase 0-1 km shear from near 20 kt at 06Z to 30 kt by 12Z. This is mostly due to strengthening low-level flow as Delta approaches. The strong low-level shear will be favorable for storm rotation as cells move from the northwestern Gulf of Mexico inland across far southern Louisiana. Any cell that can exhibit supercell structure could produce a tornado, but the threat is expected to remain isolated and primarily in the 06Z to 12Z timeframe early Friday morning. ..Broyles.. 10/09/2020
