MD 0697 CONCERNING SEVERE THUNDERSTORM WATCH 223... FOR EASTERN NC AND SOUTHEAST VA
Mesoscale Discussion 0697 NWS Storm Prediction Center Norman OK 0210 PM CDT Mon May 05 2025 Areas affected...eastern NC and southeast VA Concerning...Severe Thunderstorm Watch 223... Valid 051910Z - 052115Z The severe weather threat for Severe Thunderstorm Watch 223 continues. SUMMARY...A mixed severe hail/damaging wind threat should persist across eastern North Carolina and advance/shift north-northeast across southeast Virginia through early evening. DISCUSSION...Numerous cells have been prevalent, especially across central into eastern NC this afternoon. Here, a south-southwesterly deep-layer wind profile, per area VWPs, along with transient supercell structures has resulted in convection largely progressing northeastward thus far. But activity should pivot to a greater northerly component given the evolution of the upstream vort max/attendant mid-level jetlet. Air mass appears to be modestly unstable downstream across southeast VA with MLCAPE of 1000-1500 J/kg. This should help sustain a severe hail/damaging wind threat through early evening. Despite numerous cells and hail reports, peak severe magnitude has only reached 1 inch thus far. ..Grams.. 05/05/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0698 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF EASTERN WYOMING INTO WESTERN SOUTH DAKOTA AND FAR SOUTHWESTERN NORTH DAKOTA
Mesoscale Discussion 0698 NWS Storm Prediction Center Norman OK 0216 PM CDT Mon May 05 2025 Areas affected...portions of eastern Wyoming into western South Dakota and far southwestern North Dakota Concerning...Severe potential...Watch unlikely Valid 051916Z - 052045Z Probability of Watch Issuance...5 percent SUMMARY...A couple of severe gusts and perhaps an instance of hail may occur with the stronger storms this afternoon. The severe threat should be isolated, so a WW issuance is not expected. DISCUSSION...Multicellular high-based convection has developed along a cold front, atop a mixed boundary layer, characterized by 8-9.5 C/km 0-3 km lapse rates, over the SD/WY border. As the boundary layer further destabilizes, additional pulse-cellular and multicell storms should form along the cold front through the afternoon. Given a dry boundary layer, evaporative cooling via the stronger storm cores will promote some potential for severe gusts. With mid-level lapse rates also approaching 8 C/km amid marginal vertical wind shear, an instance of severe hail also cannot be ruled out. With the severe threat likely remaining isolated, a WW issuance is not anticipated. ..Squitieri/Gleason.. 05/05/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0696 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR PORTIONS OF FAR SOUTHEAST NEW MEXICO INTO FAR WESTERN TEXAS
Mesoscale Discussion 0696 NWS Storm Prediction Center Norman OK 0158 PM CDT Mon May 05 2025 Areas affected...portions of far southeast New Mexico into far western Texas Concerning...Severe potential...Tornado Watch likely Valid 051858Z - 052030Z Probability of Watch Issuance...80 percent SUMMARY...The severe threat is gradually increasing across southeast NM into far western TX. Supercells should organize over the next few hours, accompanied by a severe hail/wind risk. The tornado risk will initially be low, but should increase by evening. A Tornado Watch may be needed in the next few hours to address the impending severe threat. DISCUSSION...Convective initiation has recently occurred over far southeastern NM along a confluence band ahead of a surface trough, with CU gradually becoming more agitated farther south into the Trans-Pecos region of southwestern TX. Ahead of the developing/intensifying storms, continued diurnal heating beneath steepening mid-level lapse rates is supporting 500-1500 J/kg MLCAPE. With stronger 500 mb flow rotating around a parent upper low and overspreading the southern High Plains, effective bulk shear continues to increase (currently over 45 kts per 18Z mesoanalysis). As such, storms that mature and become sustained should become supercellular, with an initial severe hail/wind risk. The regional VADs and 18Z mesoanalysis currently depict weak to modest low-level shear, which should temper the tornado threat to a degree. However, a quasi-stationary baroclinic boundary, identified via visible satellite, resides from Chaves County, NM to Howard County, TX. While the tornado threat will increase later this evening with the intensification of the low-level jet, localized earlier tornado potential may exist with a supercell that can anchor to this boundary. Given the increasing severe threat, a Tornado Watch may be needed in the next few hours. ..Squitieri/Gleason.. 05/05/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0694 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PARTS OF THE LOWER MID-ATLANTIC
Mesoscale Discussion 0694 NWS Storm Prediction Center Norman OK 0116 PM CDT Mon May 05 2025 Areas affected...parts of the Lower Mid-Atlantic Concerning...Severe potential...Watch possible Valid 051816Z - 052015Z Probability of Watch Issuance...40 percent SUMMARY...Isolated severe hail and localized damaging winds are possible into late afternoon across northern Virginia into south-central Pennsylvania. This region may remain in a less favorable setup relative to areas south and west, lowering confidence for a severe thunderstorm watch. DISCUSSION...Scattered, low-topped convection has been persistent during early afternoon from northern VA into western PA. Generalized northwestward movement has stymied destabilization deeper into PA, with a gradual uptick in intensity over northern VA to western MD. Deep-layer speed shear will remain favorable (per Sterling VWP data) for further intensification, but this may be confined to the southeast extent of sustained storms and yield predominately marginal severe hail/wind. Meanwhile, more widespread deep convection is occurring across central to eastern NC. Latest trends with this activity suggest it may largely shift across southeast VA into late afternoon. Overall, the potential for a sustained hail/wind threat through peak heating appears nebulous. ..Grams/Gleason.. 05/05/2025 ...Please see www.spc.noaa.gov for graphic product...

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0214 PM CDT Mon May 05 2025 Valid 071200Z - 081200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE EDWARDS PLATEAU TO SOUTHEAST TEXAS... ...SUMMARY... Isolated severe storms are possible from the Edwards Plateau to Southeast Texas. ...Edwards Plateau to Southeast Texas... A stalled front will exist across southern Texas on Wednesday. Strong surface heating will lead to strong instability along this front in an environment featuring long, straight hodographs. Forcing will be somewhat nebulous along the front, but with uncapped forecast soundings and neutral to slightly falling heights along the frontal zone, expect at least isolated supercell development. Any supercells which develop will pose a threat for large to potentially very large hail. Storm coverage precludes higher probabilities at this time. If the front/composite outflow boundary remains onshore across the central Gulf Coast, the Marginal Risk may need to be expanded into this region. However, at this time, there is significant uncertainty how Day 2 convection will evolve which will impact the front/outflow location across Louisiana and southern Mississippi. ...Oklahoma... A weak cold front is forecast to move south through Oklahoma during the day Wednesday. Diurnal destabilization ahead of the front could provide ample instability for a few thunderstorms. Moisture quality along the front is uncertain which precludes a Marginal Risk at this time. However, if low to mid 60s dewpoints appear likely ahead of the front, sufficient instability would exist beneath the cold air aloft to support severe weather probabilities. ..Bentley.. 05/05/2025 Read more
