MD 0990 CONCERNING TORNADO WATCH 319...320... FOR SOUTHERN MO...NORTHWEST/NORTH-CENTRAL AR
Mesoscale Discussion 0990 NWS Storm Prediction Center Norman OK 0547 PM CDT Sun May 26 2024 Areas affected...Southern MO...Northwest/North-Central AR Concerning...Tornado Watch 319...320... Valid 262247Z - 270015Z The severe weather threat for Tornado Watch 319, 320 continues. SUMMARY...Discrete supercells capable of all severe hazards, including tornadoes, very large hail up to 3" in diameter, and strong gusts up to 70 mph, will persist from central Missouri into northwest/north-central AR. DISCUSSION...Several supercells have developed within the open warm sector across southern MO and northwest AR, ahead of the line of storms along the cold front approaching for the northwest. The triplet of supercells in south-central MO (i.e. Texas, Shannon, and Howell Counties) have all shown a notable increase in updraft intensity over the past half hour, with echo tops now over 50 kft in each storm. Another supercell has developed quickly just ahead of the primary line of storms across Pulaski and Phelps Counties. The easternmost two storms also are likely undergoing the splitting process, suggesting some additional strengthening and maturation is possible once this process completes. The downstream airmass is very unstable, with recent mesoanalysis estimating over 3500 J/kg of MLCAPE. Vertical shear is strong as well, with mesoanalysis estimating effective bulk shear around 50 kt. Low-level flow is somewhat veered, but strong low-level buoyancy (i.e. 0-3 km MLCAPE over 150 J/kg) should still be more than sufficient for stretching and potential tornadogenesis. Very large hail up to 3" in diameter and strong gusts up to 70 mph are possible in addition to tornadoes. The lone supercell along the far western MO/AR border continues to maintain its intensity, although it may now be trending towards a more outflow-dominant structure. However, given the strong buoyancy and robust vertical shear, some additional reorganizing is possible, with an attendant threat for tornadoes once this reorganization occurs. Very large hail up to 3" in diameter and strong gusts up to 70 mph remain possible with this storm as well. ..Mosier.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0993 CONCERNING SEVERE THUNDERSTORM WATCH 317...318...321... FOR EASTERN OH...WESTERN PA...WESTERN MD...EASTERN WV...CENTRAL VA
Mesoscale Discussion 0993 NWS Storm Prediction Center Norman OK 0622 PM CDT Sun May 26 2024 Areas affected...Eastern OH...western PA...western MD...eastern WV...central VA Concerning...Severe Thunderstorm Watch 317...318...321... Valid 262322Z - 270045Z The severe weather threat for Severe Thunderstorm Watch 317, 318, 321 continues. SUMMARY...Some damaging-wind potential will spread northeastward through the evening. DISCUSSION...A loosely organized QLCS with a history of producing some wind damage is moving across eastern OH/western PA into parts of eastern WV/central VA. While midlevel lapse rates are weak and instability gradually decreases with eastward extent, earlier diurnal heating resulted in some steepening of low-level lapse rates, and MLCAPE may remain around 500 J/kg in advance of the line this evening, though with gradually increasing MLCINH. The QLCS will likely continue to remain somewhat organized until decreasing instability and increasing inhibition becomes prohibitive later this evening. Rather strong low-level flow (noted on regional VWPs) will continue to support some wind-damage potential with this QLCS as it advances northeastward. Some threat may eventually spread out of WW 318 and WW 321 into central PA, western MD, and northern/central VA, though the need for additional watch issuance remains uncertain. ..Dean/Smith.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0992 CONCERNING TORNADO WATCH 320... FOR FAR SOUTHEAST MO...FAR SOUTHERN IL...WESTERN/CENTRAL KY...FAR SOUTHWEST IN
Mesoscale Discussion 0992 NWS Storm Prediction Center Norman OK 0618 PM CDT Sun May 26 2024 Areas affected...Far Southeast MO...Far Southern IL...Western/Central KY...Far Southwest IN Concerning...Tornado Watch 320... Valid 262318Z - 270045Z The severe weather threat for Tornado Watch 320 continues. SUMMARY...Open warm sector initiation appears to be underway from far southeast Missouri across far southern Illinois into western/central Kentucky and southern Indiana. Supercells capable of all severe hazards, including strong tornadoes, are possible. Southern IN and western/central KY will likely need an additional Tornado Watch soon. DISCUSSION...Recent visible satellite has shown increasingly deep cumulus within the warm sector well ahead of the main cold front from far southwest MO across southern IL into southwest KY and far southwest IN. Some radar returns have been recently noted with this activity as well, giving increasing confidence that at least isolated convective initiation may be realized shortly. A belt of stronger mid-level flow extends across much of this region, resulting in notable low-level veering within the VAD profiles at PAH and HPX. Ample low-level moisture and strong buoyancy exists across the region as well. Mesoanalysis estimates STP is currently from 3 to 5, with this high values expected to persist and expand northeastward with time. The result is an environment that is favorable for supercells capable of all severe hazards, including strong tornadoes. Very large hail up to 2.5" in diameter is possible as well. Some of this area is within the Tornado Watch 230, but those areas to its east including far southern IN and western KY will likely need an additional Tornado Watch soon. ..Mosier/Smith.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0991 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHEAST WISCONSIN AND FAR NORTHERN ILLINOIS
Mesoscale Discussion 0991 NWS Storm Prediction Center Norman OK 0553 PM CDT Sun May 26 2024 Areas affected...southeast Wisconsin and far northern Illinois Concerning...Severe potential...Watch unlikely Valid 262253Z - 270000Z Probability of Watch Issuance...20 percent SUMMARY...The risk for a couple brief tornadoes looks to continue for the next hour or two. The threat should quickly wane as storms approach the lake. DISCUSSION...As of 2250 UTC, regional radar analysis showed a line of storms ongoing beneath an upper low over parts of southeast WI and far northern IL. Within the line several small supercell structures have developed and have a history of brief tornadoes. Driven by strong low-level buoyancy favorable for stretching abundant ambient vertical vorticity, the risk for brief tornadoes looks to continue for another hour or two. The most favorable location for the tornado risk appears to be the northern most section where the line orientation is more orthogonal to the deep-layer flow. Still, brief tornadoes are possible with any small supercell structures able to develop. Storms should begin to weaken as they encounter the lake breeze boundary where temperatures fall to the low 60s and inhibition increases. Given the limited coverage and short duration, a WW is unlikely, though trends will be monitored. ..Lyons.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LOT...MKX...

MD 0988 CONCERNING SEVERE THUNDERSTORM WATCH 317... FOR EASTERN TN...WESTERN NC...NORTHEAST GA...UPSTATE SC
Mesoscale Discussion 0988 NWS Storm Prediction Center Norman OK 0535 PM CDT Sun May 26 2024 Areas affected...Eastern TN...western NC...northeast GA...upstate SC Concerning...Severe Thunderstorm Watch 317... Valid 262235Z - 270000Z The severe weather threat for Severe Thunderstorm Watch 317 continues. SUMMARY...Some threat for damaging wind and hail will persist into the evening. New watch issuance is expected shortly. DISCUSSION...A few supercells have developed from southwest NC into upstate SC, within a moderately unstable environment. The GSP VWP depicts rather strong mid/upper-level flow, and 40+ kt of effective shear, which is sufficient to maintain supercells. While midlevel lapse rates are not particularly strong, the moderate instability and favorable storm mode will support a hail threat with the strongest cells. The supercell storm mode could also support a brief tornado threat, even though low-level shear/SRH is not particularly strong. Steep low-level lapse rates resulting from earlier strong diurnal heating will support damaging-wind potential, especially if any sort of clustering or modest upscale growth of ongoing convection can occur. With the threat expected to extend southward of WW 317, new watch issuance is expected shortly. ..Dean/Smith.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 324 TORNADO IL IN KY 262350Z - 270600Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 324 NWS Storm Prediction Center Norman OK 650 PM CDT Sun May 26 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Southeast Illinois Southern Indiana Western and Central Kentucky * Effective this Sunday night and Monday morning from 650 PM until 100 AM CDT. * Primary threats include... Several tornadoes and a couple intense tornadoes likely Widespread damaging winds and isolated significant gusts to 85 mph likely Scattered large hail and isolated very large hail events to 3 inches in diameter likely SUMMARY...Scattered supercells are forecast to move into the lower Ohio Valley early this evening and pose a risk for tornadoes, some potentially strong, and large to very large hail (up 2 to 3 inches in diameter). Severe gusts are forecast to become more prevalent later this evening as a severe squall line with embedded supercells or mesovortices moves across the Watch area. A tornado risk will probably accompany any stronger line-embedded circulations. The tornado watch area is approximately along and 90 statute miles east and west of a line from 70 miles north northeast of Evansville IN to 30 miles south southwest of Bowling Green KY. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 0989 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR CENTRAL ILLINOIS INTO WEST-CENTRAL INDIANA.
Mesoscale Discussion 0989 NWS Storm Prediction Center Norman OK 0538 PM CDT Sun May 26 2024 Areas affected...central Illinois into west-central Indiana. Concerning...Severe potential...Watch likely Valid 262238Z - 262345Z Probability of Watch Issuance...80 percent SUMMARY...The risk for damaging gusts and hail is increasing with new storms north of St Louis. A new WW may be needed. DISCUSSION...As of 2235 UTC, regional radar analysis showed a cluster of strong to severe storms (including a few supercells) has evolved along a cold front and remnant outflow boundary over eastern MO and west-central IL. Temperatures have warmed into the upper 70s F as the air mass has recovered in the wake of an expansive squall line earlier today. Steep mid-level lapse rates and surface dewpoints in the 60s to 70s F are supporting ~1000-1500 J/kg of MLCAPE. Favorable buoyancy and increasing lift ahead of the cold front/consolidating outflow should continue to support robust updrafts. 40-50 kt of vertical shear will also allow for storm organization into one or more clusters or bowing segments. Given the favorable parameter space and the potential for organized storms, the risk for damaging wind gusts and hail appears to be increasing. A new weather watch is likely. ..Lyons/Smith.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...IND...ILX...LSX...

MD 0987 CONCERNING TORNADO WATCH 320... FOR WESTERN/MIDDLE TN...FAR NORTH-CENTRAL MS...FAR SOUTHWEST KY
Mesoscale Discussion 0987 NWS Storm Prediction Center Norman OK 0518 PM CDT Sun May 26 2024 Areas affected...Western/Middle TN...Far North-Central MS...Far Southwest KY Concerning...Tornado Watch 320... Valid 262218Z - 262345Z The severe weather threat for Tornado Watch 320 continues. SUMMARY...Isolated supercell development across western Tennessee is possible, with storms capable of very large hail up to 3" in diameter and tornadoes. Anything that develops may move into middle Tennessee, so trends will be monitored for possible watch issuance across this region. DISCUSSION...Recent visible satellite imagery has shown increasing vertical depth within the cumulus field over western TN. The airmass in this region is moderately to strong buoyant, with recent mesoanalysis estimating MLCAPE ranging from 3500 J/kg near the MS River to 1500 J/kg across middle TN. This area is currently displaced south and east of the stronger ascent, but there could still be enough low-level convergence to support convective initiation, particularly if convective attempts occur in close proximity to one another. Vertical shear across the region is also very strong and the resulting environment is capable of supporting supercells capable of all severe hazards, including very large hail up to 3" in diameter and tornadoes. A portion of this region is in Tornado Watch 320, but trends will need to be monitored closely to ensure that areas across middle TN are covered if trends merit. ..Mosier/Smith.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product...

DISCUSSION...A well-organized QLCS continues to push east across the southern Appalachians and has a history of producing damaging (50-60 mph) winds. GOES imagery shows that this line continues to produce robust embedded updrafts despite moving into a region with weaker deep-layer shear. This may be due to compensating effects from higher SBCAPE on the eastern side of the Appalachians.
