Severe thunderstorm potential appears low on Sunday. ...Southern Plains to Lower MS Valley... A shortwave upper trough will pivot east on Sunday from the southern Plains to the Lower MS Valley. At the surface, low pressure over OK/KS at the beginning of the period will weaken with time, becoming elongated from the Ozarks to LA by late afternoon into the evening. A line and/or cluster of thunderstorms will likely be ongoing Sunday morning from central/eastern OK southward into north and central TX. This activity will be occurring in a warm advection regime within deep-layer southwesterly flow ahead of the upper trough and an advancing surface cold front. A weakening low-level jet and south/southeasterly surface winds ahead of the line of convection will result in wind profiles typically favorable for low-level rotation. However, greater low-level shear/SRH and better quality low-level thermodynamics will likely be offset from one another. Forecast thermodynamic profiles indicate poor low-level lapse rates and at least pockets of weak inhibition Sunday morning. This will likely limit severe/low-end tornado potential across central into eastern TX during the morning hours. By afternoon, limited heating due to widespread cloudiness and precipitation will preclude stronger destabilization downstream toward the ArkLaTex and Sabine Valley. Any stronger instability will likely remain offshore the Upper Texas and LA coasts, and severe potential is expected to remain low. ..Leitman.. 12/23/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
