Issuance Of A Severe Weather Watch Not likely
Latest NWS SPC Mesoscale Discussion…
SUMMARY…Storms may pose some risk for locally strong wind gusts and perhaps a brief tornado over southeast Alabama next few hours.
Threat appears too marginal for a weather watch.
DISCUSSION…A cluster of storms with embedded circulations and bowing segments has recently intensified over south-central AL. Activity is forming within corridor of ascent along southern extension of warm conveyor belt. Storms are approaching a minimum in boundary-layer moisture with surface dewpoints around 56 F, and some temporary weakening might occur as a result. However, low-level theta-e advection should contribute to dewpoints rising to near 60F across southeast AL next couple hours, and this should help to sustain surface-based storms next few hours. Effective-bulk shear around 40 kt and 0-1 km storm relative helicity from 200-300 m2/s2 is more than sufficient for transient embedded circulations and bowing segments, but the weak thermodynamic environment is expected to remain the primary limiting factor for a more robust severe threat.
