MD 1464 CONCERNING SEVERE THUNDERSTORM WATCH 464... FOR PORTIONS OF SOUTHEASTERN PENNSYLVANIA TO THE DELMARVA AND SOUTHERN NEW JERSEY
Mesoscale Discussion 1464 NWS Storm Prediction Center Norman OK 0555 PM CDT Thu Jun 26 2025 Areas affected...portions of southeastern Pennsylvania to the DelMarVa and southern New Jersey Concerning...Severe Thunderstorm Watch 464... Valid 262255Z - 270030Z The severe weather threat for Severe Thunderstorm Watch 464 continues. SUMMARY...Damaging gusts will remain possible across the Mid Atlantic this evening. DISCUSSION...Across northeastern portions of WW464, a cluster of thunderstorms has gradually taken on a more linear appearance early this evening. The environment ahead of these storms is largely pristine with moderate to large buoyancy and modestly steep low-level lapse rates amid weak vertical shear. This will continue to support strong updrafts with this convection through the early evening hours. Additional storm development/intensification into a loose QLCS appears likely as storms propagate east/southeastward along a remnant coastal boundary. Locally greater forcing along this boundary, and a strengthening cold pool should allow for increased forward propagation of the entire linear cluster. This suggests a continued damaging gust threat is likely, particularly from southern NJ, to eastern MD/PA and DE this evening. ..Lyons.. 06/26/2025 ...Please see www.spc.noaa.gov for graphic product...

However, the overall severe threat should remain isolated. DISCUSSION...Scattered strong thunderstorms have been increasing over the last couple of hours, particularly over southern MT. Across the northern High Plains, strong surface heating has supported upper 80s to 90 F surface temperatures, and with 9 C/km low and mid-level lapse rates in place, over 1000 J/kg MLCAPE has become commonplace. Nonetheless, deep-layer flow and subsequent shear remains modest, especially where richer low-level moisture and resultant instability are in place. Therefore, multicells and transient supercells will continue to percolate in intensity over the next few hours. Severe wind and hail are possible, but should occur on a more intermittent and isolated basis. ..Squitieri/Guyer.. 06/26/2025 ...Please see www.spc.noaa.gov for graphic product...

Valid 262231Z - 270000Z The severe weather threat for Severe Thunderstorm Watch 465 continues. SUMMARY...Strong to severe gusts remain possible for several more hours. DISCUSSION...Multiple multicells and short-line segments have loosely organized into a persistent-elongated MCS across central IA into northwestern MO along a confluence zone. These storms, likely driven eastward by a common cold pool, will continue maintain some degree of intensity given preceding surface temperatures over 90F amid low 70s dewpoints, yielding 2500+ J/kg MLCAPE and minimal convective inhibition. As such, wet downbursts in the stronger storms may still support strong to occasionally severe gusts given the favorable buoyancy and mixed boundary layer in place. ..Squitieri.. 06/26/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1461 CONCERNING TORNADO WATCH 463... FOR PORTIONS OF FAR SOUTHEAST MINNESOTA INTO CENTRAL AND SOUTHERN WISCONSIN
Mesoscale Discussion 1461 NWS Storm Prediction Center Norman OK 0453 PM CDT Thu Jun 26 2025 Areas affected...portions of far southeast Minnesota into central and southern Wisconsin Concerning...Tornado Watch 463... Valid 262153Z - 270000Z The severe weather threat for Tornado Watch 463 continues. SUMMARY...A threat for severe wind gusts and tornadoes should persist over the next few hours. This severe threat may accompany storms within an east-ward-progressing QLCS, or with storms that develop ahead of the QLCS and interact favorably with a quasi-stationary front. A downstream Tornado Watch issuance may be needed if confidence increases in more robust, downstream storms materializing. DISCUSSION...A loosely organized QLCS continued to track eastward across far eastern MN into WI, and is traversing a quasi-stationary front. Along this front, rich low-level moisture and steep low-level lapse rates are contributing to 2000-2500 J/kg MLCAPE. Along with this appreciable instability is 35-45 kts of effective bulk shear that is overspreading the boundary. Furthermore, regional VADs show hodographs with modest curvature and 200-300 m2/s2 of 0-1 km SRH. As such, ambient conditions along this boundary are favorable for the development of severe gusts and tornadoes. At the moment, the tornado threat could increase in southern WI under two scenarios. First is with QLCS segments that traverse the boundary, optimizing the ingestion of locally higher streamwise vorticity. The second scenario involves the maturation of free-warm-sector thunderstorms into supercells that can produce tornadoes while crossing the boundary and briefly ingesting cross-wise vorticity. Convective trends are currently being monitored for further storm intensification under either scenario and the subsequent need for a Tornado Watch issuance. ..Squitieri/Guyer.. 06/26/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1462 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF NORTHERN GEORGIA...THE WESTERN CAROLINAS AND EASTERN TENNESSEE
Mesoscale Discussion 1462 NWS Storm Prediction Center Norman OK 0455 PM CDT Thu Jun 26 2025 Areas affected...portions of northern Georgia...the western Carolinas and eastern Tennessee Concerning...Severe potential...Watch unlikely Valid 262155Z - 262330Z Probability of Watch Issuance...20 percent SUMMARY...Ongoing clusters of multi-cell storms will continue to pose an isolated risk for locally damaging gusts and small hail into this evening. A locally greater risk may occur across north-central GA where stronger storms are occurring. DISCUSSION...As of 2145 UTC, regional radar/satellite imagery showed several clusters of semi-organized multi-cells ongoing from northern GA, through the western Carolinas, and into far eastern TN. Over the last several hours, reports of locally damaging winds and small hail have occurred as these clusters have shifted west/southwest within a broad area of moderate to large buoyancy (MLCAPE 2000-3000 J/kg). This trend appears likely to continue into early this evening as new updraft development/intensification continues on the flanks of these established storm clusters. A locally greater severe risk may develop in vicinity of the Atlanta Metro over the next couple of hours as a stronger multi-cell cluster has emerged. Several downbursts have been noted within this cluster as multiple strong updrafts have coalesced. While deep-layer flow remains limited, very large buoyancy and strong surging outflow could support isolated severe-caliber gusts in the 55-65 mph range into early this evening. ..Lyons/Guyer.. 06/26/2025 ...Please see www.spc.noaa.gov for graphic product...

DISCUSSION...Multiple thunderstorms have matured along a confluence zone across eastern KS, where MRMS mosaic radar imagery depicts 50+ dBZ echoes well exceeding 30 kft. While vertical wind shear is weak, these storms are developing atop a moist surface airmass, characterized by 70+ F surface dewpoints. Given a well-mixed boundary layer, 8 C/km low-level lapse rates are in place, boosting MLCAPE to 3000 J/kg. As such, the stronger pulse-cellular and multicellular storms will be capable of producing wet downbursts and associated strong wind gusts. However, the overall severe threat should remain isolated. ..Squitieri/Guyer.. 06/26/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SGF...EAX...TOP...ICT...
