MD 0635 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR MID-MISSISSIPPI RIVER VALLEY TO THE SOUTHERN APPALACHIANS
Mesoscale Discussion 0635 NWS Storm Prediction Center Norman OK 0519 PM CDT Thu May 01 2025 Areas affected...Mid-Mississippi River Valley to the southern Appalachians Concerning...Severe potential...Watch unlikely Valid 012219Z - 020015Z Probability of Watch Issuance...20 percent SUMMARY...Sporadic large hail and damaging winds will be possible through the early evening hours from the Arklamiss region to the southern Appalachians. Watch issuance is not anticipated. DISCUSSION...Thunderstorms developing along a diffuse residual frontal zone/differential heating boundary draped across the mid-MS River Valley to the southern Appalachians have shown signs of steady intensification over the past hour via cloud-top cooling and an increasing in vertically integrated ice. Temperatures warming into the low 80s to the south of the boundary coupled with mid/upper 60s dewpoints are supporting 1000-2000 J/kg MLCAPE across a broad swath of the region, and 30-35 knot mid-level flow is support adequate shear for some storm organization. However, weak low-level winds (generally less than 10 knots) and steep 0-3 km lapse rates are promoting rapid cold pool expansion that is limiting storm longevity to some degree and favoring multicellular modes. A few stronger storms will be capable of severe hail (1-1.5 inches in diameter) and damaging gusts - especially if a more consolidated, cold-pool driven cluster can become established. Overall, the severe threat is expected to remain sufficiently isolated to preclude watch issuance given regionally weak forcing for ascent. ..Moore/Smith.. 05/01/2025 ...Please see www.spc.noaa.gov for graphic product...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 204 NWS Storm Prediction Center Norman OK 230 PM CDT Thu May 1 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Central Texas * Effective this Thursday afternoon and evening from 230 PM until 900 PM CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2.5 inches in diameter likely Scattered damaging wind gusts to 70 mph likely SUMMARY...Isolated but intense thunderstorms are expected to form this afternoon in a very moist and unstable air mass. Slow-moving supercells capable of very large hail appear to be the main concern. The severe thunderstorm watch area is approximately along and 40 statute miles north and south of a line from 115 miles west of Temple TX to 65 miles east southeast of Temple TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS...

Valid 012248Z - 020015Z The severe weather threat for Severe Thunderstorm Watch 204, 205 continues. SUMMARY...Scattered slow-moving severe thunderstorms will continue into the early-evening hours. Hail is the primary concern. DISCUSSION...Scattered slow-moving thunderstorms continue within a very high-instability air mass from the international border over southeast Terrell County to Leon County. Wind profiles favor storm splits and latest radar data supports this with several left-movers advancing north of the watch at times. Even so, the primary concern this evening will be for the east-west corridor to gradually sag south as the dominant updrafts should tend to drift more southerly.

Mesoscale Discussion 0639 NWS Storm Prediction Center Norman OK 0619 PM CDT Thu May 01 2025 Areas affected...2Northeast Arkansas into the lower OH River Valley Concerning...Severe potential...Watch unlikely Valid 012319Z - 020115Z Probability of Watch Issuance...5 percent SUMMARY...Isolated thunderstorms may continue to pose a severe hail and damaging wind threat through the early evening hours. Watch issuance is not anticipated. DISCUSSION...Isolated thunderstorms developing along/ahead of a mid-level trough have been more intense and persistent than initially anticipated based on an environmental analysis. Over the past 1-2 hours, these thunderstorms have intensified within a subtle theta-e/buoyancy ridge extending from northeast AR into the lower OH River Valley with a 1.75 inch hail report noted over the past hour. Deep-layer wind shear within the base of the mid-level trough axis remains fairly marginal based on regional VWP observations (20-25 knots), however, the combination of sufficient deep-layer shear and augmented buoyancy have been adequate to promote thunderstorms with weak/transient mid-level mesocyclones in the stronger cells. Storms may continue to intensify to severe levels over the next 1-2 hours as they traverse the buoyancy ridge and prior to the onset of nocturnal cooling after 01 UTC. The stronger cells may be capable of 1-1.75 inch hail and damaging gusts, though the overall coverage and duration of the threat should remain sufficiently limited to preclude watch issuance. ..Moore/Smith.. 05/01/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0638 CONCERNING SEVERE THUNDERSTORM WATCH 203... FOR SOUTHEAST OHIO INTO WESTERN WEST VIRGINIA
Mesoscale Discussion 0638 NWS Storm Prediction Center Norman OK 0550 PM CDT Thu May 01 2025 Areas affected...Southeast Ohio into western West Virginia Concerning...Severe Thunderstorm Watch 203... Valid 012250Z - 020045Z The severe weather threat for Severe Thunderstorm Watch 203 continues. SUMMARY...WW 203 will be allowed to expire at 23 UTC, but a localized corridor of wind damage potential may persist downstream of a line of thunderstorms for the next 1-2 hours. New watch issuance is not anticipated. DISCUSSION...Radar imagery from KRLX shows a convective line that was once mostly outflow-dominant attempting to established a more well-balanced updraft/downdraft convergence zone as new convection develops along the leading edge of the cold pool. Although GOES IR imagery continues to show warming cloud top temperatures (indicative of a weakening trend), lightning trends over the past 20 minutes suggest new updrafts are beginning to intensify. The onset of nocturnal cooling is gradually diminishing the thermodynamic environment downstream of this line, but VWP observations from KRLX continues to sample around 20 knots of 0-1 km bulk shear with shear vectors oriented largely orthogonal to the cold pool. Consequently, some organization/intensification of this line segment appears possible as storms move northeast along the OH river. Given the thermodynamic trends, additional watch issuance is not anticipated, but sporadic damaging winds appear possible for the next couple of hours. ..Moore.. 05/01/2025 ...Please see www.spc.noaa.gov for graphic product...

Hail and wind appear likely with some of this activity. Severe thunderstorm watch may be warranted. DISCUSSION...Satellite imagery suggests a weak short-wave trough is digging southeast across southeast CO, ahead of a more significant 500mb speed max that will translate into eastern WY later tonight. This lead feature appears instrumental in recent uptick in convection across the higher terrain of extreme southern CO into northeast NM. While moisture is a bit scant across this region, strong shear and steep 0-3km lapse rates are favorable for maturing updrafts, and some potential for supercells. With time an expanding corridor of robust convection is expected to spread/develop southeast into the TX Panhandle. Forecast soundings suggest hail could be common, along with gusty winds. ..Darrow/Smith.. 05/01/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LUB...AMA...ABQ...
