WW 338 SEVERE TSTM TX 280110Z - 280500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 338 NWS Storm Prediction Center Norman OK 810 PM CDT Mon May 27 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of South Texas * Effective this Monday night from 810 PM until Midnight CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible Isolated very large hail events to 2.5 inches in diameter possible SUMMARY...A cluster or two of severe thunderstorms will likely move across the Rio Grande into South Texas this evening. The stronger storms will be capable of severe gusts (60-70 mph) and large to very large hail (up to 2.5 inches in diameter). This activity will likely diminish by late evening into the early overnight. The severe thunderstorm watch area is approximately along and 45 statute miles east and west of a line from 10 miles north northwest of Cotulla TX to 15 miles west southwest of Mcallen TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 334...WW 335...WW 336...WW 337... AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 550. Mean storm motion vector 21030. ...Smith Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0759 PM CDT Mon May 27 2024 Valid 280100Z - 281200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF TEXAS...THE SOUTHEAST...AND THE MID ATLANTIC... ...SUMMARY... Strong to severe thunderstorms remain possible this evening into tonight across parts of the southern Plains, Southeast, and Mid Atlantic. ...OK/TX... Isolated supercells are ongoing this evening across parts of central into northeast TX. Strong to extreme instability and favorable deep-layer shear will continue to support a threat of hail (possibly in excess of 2 inches in diameter), along with localized severe gusts. The ongoing discrete supercell activity will likely tend to decrease with time later tonight, as MLCINH begins to increase with the onset of nocturnal cooling. Farther south, it remains possible that storm clusters currently over northern Mexico will move into parts of south-central into deep south TX later tonight, posing an isolated threat of hail and severe gusts before weakening. See MCD 1027 for more information. Overnight, elevated convection may develop across parts of north TX into OK, near/north of a nearly stationary surface boundary. The coverage and organization of this late development remains uncertain, but moderate to strong elevated buoyancy will support at least isolated hail with the strongest storms. ...South AL/GA into north FL and the FL Peninsula... Scattered strong to occasionally severe storms are ongoing this evening across parts of south AL/GA and extreme north FL. Rich low-level moisture, strong buoyancy, and sufficient deep-layer shear will continue to support some threat for damaging wind and hail for much of the evening as storms spread southeastward. See MCD 1026 for more information. ...Parts of the Mid Atlantic into the Northeast... Widely scattered storms are expected to continue through the evening from parts of the Mid Atlantic into the Northeast, as a mid/upper-level shortwave trough moves across the region. Favorable low-level and deep-layer shear will continue to support some threat for isolated hail and damaging wind and perhaps a tornado, before storm coverage and intensity wanes later tonight.

MD 1024 CONCERNING SEVERE THUNDERSTORM WATCH 336... FOR NORTH/CENTRAL TX THROUGH TE TX HILL COUNTRY
Mesoscale Discussion 1024 NWS Storm Prediction Center Norman OK 0636 PM CDT Mon May 27 2024 Areas affected...North/Central TX through te TX Hill Country Concerning...Severe Thunderstorm Watch 336... Valid 272336Z - 280100Z The severe weather threat for Severe Thunderstorm Watch 336 continues. SUMMARY...Threat for very large hail up to 3" in diameter and severe gusts around 60-70 mph will continue from north/central Texas into the Texas Hill Country. DISCUSSION...Strong to severe thunderstorms continue to develop within the very warm and moist airmass that exists from the TX Hill Country north and eastward across the remainder of the state. Large-scale ascent across the region remains fairly modest, with the low-level moisture convergence providing the primary mechanism for convective initiation. In addition to robust buoyancy, strong vertical shear exists over the region as well, with long hodographs favoring splitting storms. The overall environment supports the persistence of both left and right splits, with storm interactions dictating updraft survival. This is particularly true across central TX, where greater storm coverage exists, likely a result of subtle large-scale ascent aiding overall convective initiation and maturation. The very strong buoyancy and shear will continue to support the potential for very large hail up to 3" in diameter across the entire region. Steep low-level lapse rates will also support the development of strong downbursts capable of producing severe gusts around 60-70 mph. Weak surface winds are expected to keep the tornado threat low, although non-zero given the supercellular storm mode. ..Mosier.. 05/27/2024 ...Please see www.spc.noaa.gov for graphic product...
