SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1115 PM CST Fri Dec 25 2020 Valid 261200Z - 271200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected in the continental United States. ...Discussion... Weak convection is expected in association with a strong short-wave trough over the northern inter-mountain region today. This feature is currently approaching the OR/northern CA Coast and isolated thunderstorms are noted just offshore at 05z. However, while a few flashes of lightning are expected until sunrise this morning over this region, buoyancy will be quite limited farther inland and the probability for thunderstorms should remain too low to warrant a 10 percent risk for lightning. ..Darrow.. 12/26/2020
