Isolated strong to severe thunderstorms appear possible mainly Tuesday morning across parts of east Texas into the lower Mississippi Valley. ...East Texas into the Lower Mississippi Valley... Multiple clusters of thunderstorms will probably be ongoing at the start of the period Tuesday morning from parts of east TX into the lower MS Valley. Some of this activity could be strong to locally severe, as a moist and modestly unstable airmass will be in place across this region. A low-amplitude, southern-stream shortwave trough is forecast to move quickly northeastward across the Southeast and away from the lower MS Valley through the day. Corresponding deep-layer shear should gradually weaken through Tuesday afternoon as the related mid-level flow likewise lessens. Still, there should be sufficient shear for at least modest updraft organization with any ongoing convection Tuesday morning. Occasional strong to damaging winds and perhaps isolated severe hail may occur with more robust updrafts, before convection either weakens or moves offshore. The potential for additional robust thunderstorm development in the wake of the morning activity appears highly uncertain/conditional. But, some guidance suggests that the airmass will attempt to recover along/east of a dryline across east TX into the ArkLaTex vicinity. Regardless, large-scale subsidence behind the shortwave trough should tend to hinder additional development both along the dryline and with a slowly southeastward-moving cold front. ..Gleason.. 03/03/2024 Read more View the full article Quote Link to comment Share on other sites More sharing options...
