MD 1655 CONCERNING SEVERE THUNDERSTORM WATCH 492... FOR PARTS OF WESTERN PA AND EASTERN/CENTRAL OH
Mesoscale Discussion 1655 NWS Storm Prediction Center Norman OK 0547 PM CDT Sat Jul 18 2026 Areas affected...Parts of western PA and eastern/central OH Concerning...Severe Thunderstorm Watch 492... Valid 182247Z - 190045Z The severe weather threat for Severe Thunderstorm Watch 492 continues. SUMMARY...The most favorable corridor for damaging wind gusts will extend from parts of western Pennsylvania into eastern and central Ohio for the next couple of hours -- within Severe Thunderstorm Watch 492. DISCUSSION...Loosely organized clusters of thunderstorms are tracking southeastward ahead of a cold front extending from western PA into eastern/central OH. The PBZ and CCX VWPs are sampling around 45 kt of west-northwesterly 0-6 km shear oriented perpendicular to the gust fronts of these clusters. This favorable shear orientation and a narrow ENE-WSW-oriented corridor of warm/moist inflow will continue to support damaging wind gusts over the next couple of hours. Thereafter, storms will eventually move southeastward into an air mass that has been overturned by earlier convection (temperatures in the lower 70s in southwestern PA). This should result in a gradual decrease in storm intensity into this evening. ..Weinman.. 07/18/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...CTP...PBZ...RLX...CLE...ILN...

MD 1656 CONCERNING SEVERE THUNDERSTORM WATCH 497... FOR PARTS OF WESTERN/CENTRAL MT
Mesoscale Discussion 1656 NWS Storm Prediction Center Norman OK 0635 PM CDT Sat Jul 18 2026 Areas affected...Parts of western/central MT Concerning...Severe Thunderstorm Watch 497... Valid 182335Z - 190130Z The severe weather threat for Severe Thunderstorm Watch 497 continues. SUMMARY...Some increase in severe-wind potential is possible through the evening. Isolated hail also remains possible. DISCUSSION...As of 2330 UTC, widely scattered storms are ongoing across parts of western MT. In the short term, the severe threat may remain rather isolated, with moderate buoyancy and steep lapse rates supporting a threat of localized hail and severe gusts. With time, as both midlevel flow and storm coverage gradually strengthen over the region, one or more outflow-driven clusters may evolve and pose an increasing severe-wind threat into this evening. Some severe threat may eventually develop north of WW 497, and trends will continue to be monitored regarding the need for local watch expansion. ..Dean.. 07/18/2026 ...Please see www.spc.noaa.gov for graphic product...

DISCUSSION...A loosely organized band or thunderstorms is tracking eastward into Long Island. The KOKX VWP is sampling around 45 kt of line-orthogonal 0-6 km shear, which may continue to support an organized cold pool as it continues eastward, despite marginal buoyancy. Given the established cold pool, 30-40 kt of flow in the lowest 2 km, and at least neutral static stability in the boundary layer, strong to locally damaging wind gusts will be possible over the next hour or so. The overall severe risk is expected to remain too localized/marginal for a watch. ..Weinman/Hart.. 07/18/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OKX...
