Valid 160022Z - 160215Z The severe weather threat for Severe Thunderstorm Watch 54 continues. SUMMARY...A severe threat is likely to continue for a several more hours. Large hail and wind damage will be the primary threats. Weather watch issuance will likely be needed to replace WW 54. DISCUSSION...The latest radar from Laughlin Air Force Base shows a cluster of widely spaced severe storms in the vicinity of the Rio Grande River, near and to the south of Eagle Pass and to the south-southwest of Laredo. These storms are developing to the east of an axis of moderate to strong instability, where the RAP has MLCAPE in the 1500 to 3000 J/kg range. Strong surface heating, weak large-scale ascent and low-level convergence will likely continue to support continued convective development for several more hours this evening. The instability along with 700-500 mb lapse rates of 7.5 to 8 C/km, and 55 knots of 0-6 km shear, evident on the Del Rio WSR-88 VWP, will be favorable for supercells with large hail. Hailstones near 2 inches in diameter will be possible with the strongest of cells. Wind damage will also be possible. ...Broyles.. 03/16/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!4PzdZaWfovfzWt3EI8zKpTgmoDuq8UP6JunvREGlrC6mw-e9JBOiWUXiPaksv24VbpFoV7px1= XCOnuVHM2XYZPrHCQk$ for graphic product...
