Severe thunderstorms are not forecast through tonight. ...20Z Update... Minor changes have been made to the general thunderstorm area across parts of south FL and the Keys. Isolated convection still appears possible later tonight into early Sunday morning. ..Gleason.. 01/13/2024 .PREV DISCUSSION... /ISSUED 0957 AM CST Sat Jan 13 2024/ ...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.
