137 ACUS11 KWNS 081620 SWOMCD SPC MCD 081619 LAZ000-TXZ000-081815- Mesoscale Discussion 1558 NWS Storm Prediction Center Norman OK 1119 AM CDT Mon Jul 08 2024 Areas affected...parts of southeastern Texas and southwestern/west central Louisiana Concerning...Tornado Watch 514... Valid 081619Z - 081815Z The severe weather threat for Tornado Watch 514 continues. SUMMARY...Within and ahead of outer bands of Beryl, the risk for supercells with potential to produce tornadoes may undergo a substantive increase through 1-3 PM CDT. DISCUSSION...The low-level circulation center of Beryl is progressing slowly northward, near/west through north of the Houston Intercontinental vicinity. VWP data from KGHX indicates that low-level wind fields have veered to a south-southwesterly component with hodographs becoming more linear, and downward mixing of drier air is lowering surface dew points into the lower 70s F across much of the Greater Houston area. On the eastern to northeastern periphery of Beryl, surface dew points continue to rise through the upper 70s F, in the presence of enlarging clockwise-curved low-level hodographs closer to the Sabine River and into southwestern and west central Louisiana. Coupled with further boundary-layer destabilization, aided by daytime heating beneath the eastern periphery of the mid-level warm core, the potential for tornadoes may begin to substantively increase through 18-20Z. This may include with evolving supercells within the north-northeastward pivoting outer bands, and perhaps discretely to their north and east. ..Kerr.. 07/08/2024 ...Please see www.spc.noaa.gov for graphic product...
