Severe thunderstorm threat is negligible today. ...Discussion... Intense 12hr midlevel height falls will spread across New England over the next 30 hr in response to an upper trough that is expected to advance across the Great Lakes toward Georgian Bay by the end of the period. Strong low-level warm advection early in the period will likely contribute to ascent necessary for elevated convection. Forecast soundings suggest parcels lifted near 850mb will yield MUCAPE on the order of 500 J/kg, more than adequate for lightning discharge in the more robust updrafts. Farther south, weak buoyancy lingers across south FL. Weak low-level convergence along the front may prove adequate for instigating surface-based updrafts capable of generating lightning. Primary threat should be prior to 21z. ..Darrow/Weinman.. 01/13/2024 Read more View the full article Quote
