WW 337 SEVERE TSTM AL FL CW 272210Z - 280300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 337 NWS Storm Prediction Center Norman OK 510 PM CDT Mon May 27 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southern Alabama Western Florida Panhandle Coastal Waters * Effective this Monday afternoon and evening from 510 PM until 1000 PM CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...A couple of clusters of strong to severe thunderstorms will likely continue to develop late this afternoon into the evening. The stronger storms will potentially yield a risk for large hail and strong to severe gusts (55-70 mph) capable of wind damage. The severe thunderstorm watch area is approximately along and 65 statute miles north and south of a line from 15 miles northwest of Mobile AL to 30 miles south southeast of Troy AL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). 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 333...WW 334...WW 335...WW 336... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500.

MD 1026 CONCERNING SEVERE THUNDERSTORM WATCH 334... FOR SOUTHERN GEORGIA
Mesoscale Discussion 1026 NWS Storm Prediction Center Norman OK 0701 PM CDT Mon May 27 2024 Areas affected...Southern Georgia Concerning...Severe Thunderstorm Watch 334... Valid 280001Z - 280130Z The severe weather threat for Severe Thunderstorm Watch 334 continues. SUMMARY...The severe threat across WW 334 continues, but will be more focused over the next hour or so across south-central Georgia where a more organized thunderstorm cluster will pose a severe wind threat. DISCUSSION...Convection continues to percolate across much of southern AL into central/southern GA. Recent MRMS trends show that the clustered nature of the storms has limited storm longevity and organization thus far, though a few more intense updrafts remain evident in GOES IR imagery, suggesting that sporadic/isolated severe hail and damaging winds remain possible across the region. A more focused/higher severe threat has materialized across far southern GA where cold pool amalgamation has resulted in a more organized cluster. Radar imagery from KVAX shows hints at horizontal convective rolls extending southwest to northeast aligned with the low-level wind. This feature suggests that a well-mixed, buoyant boundary layer remains in place immediately downstream of this cluster, and that low-level convergence should be enhanced on the southwestern flank of the cold pool, resulting in an increasingly southward propagation of the cluster. Consequently, the threat for damaging winds appears to be increasing across southern GA and potentially into far northern FL. ..Moore.. 05/28/2024 ...Please see www.spc.noaa.gov for graphic product...

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...

SPC 0100Z Day 1 Outlook
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. See MCD 1025 for more information. ..Dean.. 05/28/2024 Read more
