WW 334 SEVERE TSTM AL GA SC CW 271810Z - 280200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 334 NWS Storm Prediction Center Norman OK 210 PM EDT Mon May 27 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southeast Alabama Central and Southern Georgia Southern South Carolina Coastal Waters * Effective this Monday afternoon and evening from 210 PM until 1000 PM EDT. * Primary threats include... Scattered damaging wind gusts to 65 mph likely Isolated large hail events to 1.5 inches in diameter possible A tornado or two possible SUMMARY...Scattered severe storms are expected to develop, initially this afternoon near a remnant boundary across central/south-central Georgia, eastward into southern South Carolina as well as southeast Alabama. The severe thunderstorm watch area is approximately along and 55 statute miles north and south of a line from 5 miles southwest of Troy AL to 25 miles south southeast of Charleston SC. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). 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... AVIATION...A few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 55 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 27025. ...Guyer Read more

MD 1023 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EASTERN IOWA INTO CENTRAL ILLINOIS
Mesoscale Discussion 1023 NWS Storm Prediction Center Norman OK 0510 PM CDT Mon May 27 2024 Areas affected...Eastern Iowa into central Illinois Concerning...Severe potential...Watch unlikely Valid 272210Z - 280015Z Probability of Watch Issuance...20 percent SUMMARY...Isolated thunderstorms will continue to pose a severe wind/hail risk as they move out of eastern Iowa and into far northwest Illinois. However, a gradual weakening trend is anticipated towards central IL later this evening. DISCUSSION...Isolated to scattered thunderstorms across eastern IA continue to show periodic intensification to severe limits based on regional velocity data and MRMS vertical ice/MESH metrics. Recent RAP mesoanalyses continue to show a supportive thermodynamic environment across eastern IA into northwest IL with MLCAPE around 500 J/kg and nearly straight hodographs are noted in regional VWPs with around 30 knots of 0-6 km BWD. However, this activity appears to be slowly outrunning the cooler temperatures aloft and better low-level moisture that is supporting the buoyancy (downstream observations across central to northern IL show dewpoints mixing out into the upper 40s and low 50s). Some severe wind/hail threat will continue for the next few hours, but a gradual weakening trend appears likely as storms move deeper into IL later this evening. Given the limited environment and coverage of the threat, watch issuance is not anticipated. ..Moore/Smith.. 05/27/2024 ...Please see www.spc.noaa.gov for graphic product...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 336 NWS Storm Prediction Center Norman OK 350 PM CDT Mon May 27 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of North and Central Texas * Effective this Monday afternoon and evening from 350 PM until 1000 PM CDT. * Primary threats include... Scattered large hail likely with isolated very large hail events to 3.5 inches in diameter possible Scattered damaging winds and isolated significant gusts to 75 mph possible A tornado or two possible SUMMARY...Thunderstorms are expected to quickly develop and intensify through late afternoon and early evening within a moist and extremely unstable environment.

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...

MD 1025 CONCERNING SEVERE THUNDERSTORM WATCH 333...335... FOR SOUTHEAST PENNSYLVANIA INTO THE DELMARVA REGION
Mesoscale Discussion 1025 NWS Storm Prediction Center Norman OK 0640 PM CDT Mon May 27 2024 Areas affected...Southeast Pennsylvania into the Delmarva region Concerning...Severe Thunderstorm Watch 333...335... Valid 272340Z - 280145Z The severe weather threat for Severe Thunderstorm Watch 333, 335 continues. SUMMARY...The severe threat continues primarily for the southern half of WW 333, especially downstream of a cluster of organized convection moving across the Delmarva region. DISCUSSION...Gradual and modest air mass recovery has been ongoing over the past couple of hours across central to eastern PA and NJ in the wake of earlier convection. Recent RAP mesoanalysis estimates suggest MLCAPE has increased to around 1000 J/kg across eastern PA/NJ with strong deep-layer wind shear remaining over the region ahead of the approaching upper wave. Thunderstorms that have recently developed along a subtle surface confluence axis may see intensification to severe limits over the next hour or so before the onset of more substantial nocturnal cooling/stabilization. Further south, a cluster of discrete/semi-discrete cells has evolved over the Delmarva region. This activity remains well within the buoyancy axis where low 70s dewpoints are supporting MLCAPE closer to 1500 J/kg. With moisture continuing to increase downstream into DE, storm maintenance and/or intensification is expected with a continued threat for damaging winds and large hail. A brief tornado threat may materialize across the northern Chesapeake Bay area within the hour given modest (around 100 m2/s2) 0-1 km SRH just ahead of the ongoing storms, but southwesterly winds further downstream into DE suggest weaker low-level SRH and lower tornado potential. ..Moore.. 05/27/2024 ...Please see www.spc.noaa.gov for graphic product...
