SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0636 PM CST Sat Feb 08 2025 Valid 090100Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms may be noted early this evening. ...01z Update... Low-amplitude short-wave trough is ejecting across the Great Lakes/Ohio Valley region early this evening. Primary corridor for large-scale ascent is now focusing across the upper OH Valley into the northern Middle Atlantic, as LLJ strengthens ahead of the short wave. Widespread precipitation is noted within the warm advection zone but elevated convection is gradually weakening, and only a few flashes of lightning may be noted for the next few hours along the nose of the LLJ. Additionally, shallow weak convection is currently observed along the trailing cold front across KY into TN, but this activity has struggled to attain heights necessary for lightning. This activity will likely remain too shallow the rest of tonight for any meaningful risk for thunderstorms. 01z adjustments will reflect lower confidence in lightning, thus severe probabilities will be removed. ..Darrow.. 02/09/2025
