MD 0884 CONCERNING TORNADO WATCH 292...295... FOR PARTS OF SOUTHEAST INTO EAST-CENTRAL OKLAHOMA
Mesoscale Discussion 0884 NWS Storm Prediction Center Norman OK 0457 PM CDT Mon May 19 2025 Areas affected...Parts of southeast into east-central Oklahoma Concerning...Tornado Watch 292...295... Valid 192157Z - 192330Z The severe weather threat for Tornado Watch 292, 295 continues. SUMMARY...Storms over south-central/southeast Oklahoma should spread northeastward into an increasingly favorable corridor for supercell intensification over the next few hours -- with a corresponding increase in tornado potential. DISCUSSION...A somewhat messy convective evolution with embedded supercell clusters is evolving from north-central TX into south-central/southeast OK as of 2150Z. Ahead of this activity, a relatively pristine warm/moist sector is in place -- characterized by lower 70s dewpoints beneath a steep midlevel lapse rate plume (sampled by earlier special soundings across the region). This is contributing to upwards of 3000 J/kg MLCAPE. A 40-45 kt low-level jet over the warm sector is yielding clockwise-curved hodographs, with around 270 m2/s2 effective SRH. This should support a gradual intensification of the ongoing convection into semi-discrete supercells over the next few hours, and ample residence time in the high-helicity air will favor an increasing risk of tornadoes (some of which could become strong to intense if a semi-discrete supercell-mode can evolve). Very large hail and damaging winds will also remain a concern with these storms. ..Weinman.. 05/19/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SHV...TSA...FWD...OUN...

MD 0883 CONCERNING TORNADO WATCH 292... FOR PARTS OF EAST CENTRAL AND NORTHEASTERN OKLAHOMA
Mesoscale Discussion 0883 NWS Storm Prediction Center Norman OK 0338 PM CDT Mon May 19 2025 Areas affected...parts of east central and northeastern Oklahoma Concerning...Tornado Watch 292... Valid 192038Z - 192245Z The severe weather threat for Tornado Watch 292 continues. SUMMARY...Long-lived discrete supercell development accompanied by potential for a couple of strong tornadoes remains possible, while spreading across the I-40 into I-44 corridors of northeastern Oklahoma through 5-7 PM CDT. DISCUSSION...A clustering of strong to severe storms, including a couple of sustained tornado producing supercells continues to develop north/northeastward, within a seasonably moist and moderately unstable warm sector, well east of the dryline. This has been supported by a weak lead mid-level perturbation progressing toward the Ozark Plateau. The supercells are generally focused along/west of a strengthening (40+ kt) 850 mb jet axis, and now within an area of stronger surface pressure falls (including 2-3+ mb/2 hourly, evident in 20Z surface observations). As long as the supercells remain more or less discrete, the environment remains conducive to additional tornado development, with perhaps some increase in potential for a strong tornado or two into early evening. ..Kerr.. 05/19/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0881 CONCERNING TORNADO WATCH 293...294... FOR SOUTHEAST NEBRASKA TO NORTHEAST KANSAS
Mesoscale Discussion 0881 NWS Storm Prediction Center Norman OK 0312 PM CDT Mon May 19 2025 Areas affected...Southeast Nebraska to northeast Kansas Concerning...Tornado Watch 293...294... Valid 192012Z - 192215Z The severe weather threat for Tornado Watch 293, 294 continues. SUMMARY...The threat for large hail, severe wind, and tornadoes continues across southeast Nebraska into northeast Kansas, though a couple of localized corridors of higher tornado potential are becoming apparent. DISCUSSION...Convection developing along a cold front/confluence axis across southeast NE continues to intensify, and a few cells have begun to show signs of persistent mid-level rotation based on KUEX velocity imagery. Additional cells continue to develop along the boundary, so storm coverage is expected to increase over the next 1-2 hours. Ambient vorticity along the strongly confluent boundary coupled with strong, organizing updrafts deepening atop the boundary should support a tornado threat for the next few hours, though tornado strength/longevity may be modulated by destructive storm interactions. Regardless, a large hail threat will continue with 1 inch hail recently reported. Further southeast into northeast KS, deep convection is developing along the dryline per GOES imagery and latest lightning data. Modifying an 18 UTC OAX sounding based on warm sector observations suggests that sufficient buoyancy and low-level helicity is in place to support STP values up to 2 downstream of the developing storms. Strong cross-boundary flow should promote supercellular storm modes with a strong tornado and very large hail threat for the next couple of hours along the KS/NE border. ..Moore.. 05/19/2025 ...Please see www.spc.noaa.gov for graphic product...

Watch issuance is expected. DISCUSSION...Elevated convection continues to rapidly develop northward across northern Missouri and is spreading into south-central Iowa within a zone of strong warm air advection between 925-850 mb. Despite being elevated in nature, MUCAPE and effective shear downstream across IA and northeast MO remains very favorable for organized convection (MUCAPE 1500-2000 J/kg and 45-55 knots respectively). Storm mode will likely remain a mix of supercells and clusters, but intense updrafts will be capable of producing severe hail, most likely between 1 to 2 inches diameter. A severe thunderstorm watch will be needed soon to address this threat. ..Moore/Hart.. 05/19/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LSX...DVN...DMX...EAX...OAX...

MD 0880 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR NORTHEAST ARKANSAS AND ADJACENT PORTIONS OF MISSISSIPPI...TENNESSEE...AND MISSOURI
Mesoscale Discussion 0880 NWS Storm Prediction Center Norman OK 0234 PM CDT Mon May 19 2025 Areas affected...Northeast Arkansas and adjacent portions of Mississippi...Tennessee...and Missouri Concerning...Severe potential...Watch unlikely Valid 191934Z - 192130Z Probability of Watch Issuance...5 percent SUMMARY...Isolated convection developing across northeast Arkansas/parts of the mid-Mississippi River Valley may sufficiently intensify to pose a hail/wind threat through late afternoon. Coverage of strong/severe storms should remain too limited for watch issuance. DISCUSSION...Over the past hour, shallow convection has percolated across northeast AR as temperatures warm into the mid 80s amid low to mid 70 dewpoints. Within the last 15 minutes, GOES IR imagery shows a few deeper towers developing, suggesting that this convection is beginning to overcome lingering MLCIN and fully realizing the high-buoyancy environment (MLCAPE estimated between 2500-3000 J/kg). 30-40 knot flow between 5-6 km sampled by regional VWPs is supporting bulk shear values around 30 knots, which should be sufficient to support a few stronger/severe cells through late afternoon. Large hail should be the primary concern with deeper/stronger cells, though numerous storms in close proximity may promote destructive storm interactions and/or some degree of clustering with an more pronounced damaging wind threat. In general, severe storm coverage should remain sufficiently limited due to weak forcing for ascent to preclude watch issuance at this time (though a more robust/widespread severe threat is expected to emerge later tonight). ..Moore/Hart.. 05/19/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0879 CONCERNING TORNADO WATCH 292... FOR PARTS OF NORTH CENTRAL TEXAS INTO SOUTH CENTRAL OKLAHOMA
Mesoscale Discussion 0879 NWS Storm Prediction Center Norman OK 0145 PM CDT Mon May 19 2025 Areas affected...parts of north central Texas into south central Oklahoma Concerning...Tornado Watch 292... Valid 191845Z - 192045Z The severe weather threat for Tornado Watch 292 continues. SUMMARY...Intensifying supercells increasingly probable through 4-7 PM CDT, initially posing a risk for large to giant hail, before the risk for a couple of strong tornadoes increases toward early evening. A new tornado watch is likely across parts of north central Texas. DISCUSSION...Even with downward mixing of momentum, within the more strongly heated and deeply mixed boundary layer to the west of the dryline, west-southwesterly surface gusts remain relatively modest, as a significant mid-level trough begins to pivot northeast of the southern high plains. However, as this trough gradually takes on more of a negative tilt, strongest mid/upper forcing for ascent within its base is forecast to overspread the dryline across the Red River vicinity through 21-00Z. Sustained intensifying thunderstorm development may now be underway along the sharpening dryline to the southwest of Wichita Falls TX. This seems likely to persist, as inhibition continues to erode with further insolation and cooling aloft. A notable further increase in number of storms seems probable with the forcing for ascent, particularly focused south of Chickasha OK into the Mineral Wells TX vicinity, before spreading northeastward/eastward. Thermodynamic profiles characterized by steep lower/mid-tropospheric lapse rates and CAPE approaching 4000 j/kg will probably support a few intense supercells, in the presence of strongly sheared 40-50 kt southwesterly deep-layer mean flow. Toward 20/00Z, initially modest low-level hodographs may begin to enlarge and become more conducive to tornado potential across the Red River vicinity near/east of the Ardmore vicinity. ..Kerr.. 05/19/2025 ...Please see www.spc.noaa.gov for graphic product...
