Administrators NorthGeorgiaWX Posted January 13 Administrators Posted January 13 SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0957 AM CST Sat Jan 13 2024 Valid 131630Z - 141200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast in the conterminous U.S. through tonight. ...Synopsis... A strong surface cyclone over the Great Lakes will continue to lift to the northeast into eastern Canada over the next 24 hours. A trailing cold front draped across the western Atlantic into the southern Florida Peninsula will gradually shift east/southeast through the day. Thunderstorm potential will be focused along and behind this front for today and tonight. ...Southern Florida... A narrow band of convection has been ongoing along the cold front this morning as it migrates south. While a few deeper cells have been observed from regional radars, these stronger pulses have been relatively short-lived. Despite 40-50 knot mid-level flow, a combination of poor lapse rates near 700-600 mb and decreasing forcing for ascent have limited storm longevity/intensity thus far and should continue to be detrimental to severe potential through the remainder of the afternoon. A second round of isolated showers/weak thunderstorms is anticipated late tonight into early Sunday morning as weak ascent ahead of an approaching mid-level disturbance overspreads meager (500 J/kg MUCAPE or less) post-frontal buoyancy rooted above the frontal inversion. ..Moore.. 01/13/2024 Read more View the full article Quote
