MD 1373 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR NORTHERN NORTH CAROLINA AND FAR SOUTHERN VIRGINIA
Mesoscale Discussion 1373 NWS Storm Prediction Center Norman OK 0530 PM CDT Thu Jun 19 2025 Areas affected...Northern North Carolina and far southern Virginia Concerning...Severe potential...Watch possible Valid 192230Z - 200030Z Probability of Watch Issuance...60 percent SUMMARY...A bowing line segment will likely pose a severe wind risk along the North Carolina/Virginia border region over the next few hours. Watch issuance is probable if the band remains south of WW 442. DISCUSSION...A convective cluster has quickly organized into a compact bowing line segment across northern NC over the past 60-90 minutes. TRDU velocity imagery shows a consolidating outflow boundary associated with this line as well as severe winds at about 2-3 kft ARL, and GOES IR imagery shows rapid intensification via cooling cloud-top temperatures. This band will likely propagate to the east/northeast along a diffuse outflow boundary draped from eastern VA into northern NC. Ahead of the outflow, temperatures in the upper 80s and low 90s are supporting a regional buoyancy maximum (around 2000 J/kg MLCAPE) that, when coupled with 30-35 knots of effective bulk shear, should promote further intensification over the next couple of hours. Consequently, the severe wind threat should increase downstream along the VA/NC border. It remains unclear how far south the outflow will propagate as this intensification occurs, but watch issuance is probable if the band remains south of WW 442. ..Moore/Smith.. 06/19/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1375 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR CENTRAL PLAINS
Mesoscale Discussion 1375 NWS Storm Prediction Center Norman OK 0629 PM CDT Thu Jun 19 2025 Areas affected...Central Plains Concerning...Severe potential...Watch unlikely Valid 192329Z - 200130Z Probability of Watch Issuance...20 percent SUMMARY...Isolated severe thunderstorms are possible this evening along the dryline. Hail and wind are the primary concerns, but storm coverage suggests a watch is unlikely. DISCUSSION...Strong boundary-layer heating has contributed to very steep 0-3km lapse rates along the dryline this afternoon as temperatures warmed through the mid and upper 90s. As a result, CINH is minimal and low-level convergence appears more than adequate for isolated robust convection from northern NE, southwest across western KS into southeast CO. Slow-moving supercells may continue along this corridor deep into the evening hours as a LLJ is expected to strengthen across the central Plains after sunset. However, storm coverage may prove too sparse to warrant a severe thunderstorm watch. ..Darrow/Smith.. 06/19/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1374 CONCERNING SEVERE THUNDERSTORM WATCH 443... FOR WESTERN TO CENTRAL MAINE
Mesoscale Discussion 1374 NWS Storm Prediction Center Norman OK 0559 PM CDT Thu Jun 19 2025 Areas affected...Western to central Maine Concerning...Severe Thunderstorm Watch 443... Valid 192259Z - 200100Z The severe weather threat for Severe Thunderstorm Watch 443 continues. SUMMARY...An intense line segment and a few developing supercells will continue to pose a severe hail/wind risk for the next 1-2 hours across western to central Maine. DISCUSSION...Recent GOES imagery shows intensifying updrafts within a convective band across northwest/western ME, as well as the development of a couple of supercells across west-central ME over the past hour. This is occurring as the band and weak mid-level ascent impinge on a buoyancy axis spanning from New England into northwestern ME. This corridor of 1000-1500 J/kg MLCAPE is fairly narrow based on visible imagery with stable billow clouds noted across central ME where temperatures remain in the low 70s. As such, the potential for severe hail/wind gusts will likely be most widespread over the next couple of hours before convection moves into the more stable air mass. However, well-established mesocyclones, such as the one embedded within the convective line, will continue to pose at least an isolated severe threat through 03 UTC across the eastern extent of WW 443. ..Moore.. 06/19/2025 ...Please see www.spc.noaa.gov for graphic product...
