Isolated to scattered strong to severe storms are possible Monday afternoon and evening across portions of eastern Oklahoma and northeast Texas into the Mid-South. ...Synopsis... Deep-layer southwesterly flow will increase across the southern Plains to the Ohio Valley and Northeast as the upper trough over the Upper Midwest and northern/central Plains and an upper trough over the Southwest begin to phase. At the surface, a cold front is forecast to extend from southern Lower MI to northern OK Tuesday morning. This boundary will develop slowly southeast through the period, becoming oriented from NY to the Mid-South to north-central TX by Wednesday morning. During the afternoon, a dryline will be oriented across central TX. Ahead of the surface front and east of the dryline, increasing southerly low-level flow will transport 60s F dewpoints across the Sabine Valley into AR. The surface front and dryline will serve as a focus for strong to severe thunderstorm development during the afternoon/evening. ...OK/TX to the Mid-South... Convective development is likely near the surface triple point and cold front by 00z as forcing for ascent impinges on the moist and moderately unstable airmass in the eastern OK/AR vicinity. Thunderstorm coverage will likely increase through the evening as a modest low-level jet develops. Any discrete convection that develops will pose a risk for large hail and perhaps a tornado or two. However, convection may become linear along the surface front rather quickly, with an accompanying increase in damaging wind potential. Severe potential along the dryline across parts of OK/TX is more uncertain/conditional. Capping and nebulous large-scale ascent (especially with southwest extent across TX) may suppress convection. However, if a storm can develop within the favorable thermodynamic and kinematic parameter space, large hail will be possible. ..Leitman.. 05/03/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
