Thunderstorms with hail and isolated severe gusts will be possible on Sunday from parts of the lower to mid Missouri Valley into the central and northern Plains. ...Synopsis... Mid-level ridging will build across the central portion of the CONUS with a deepening trough moving from Quebec into the Northeast on Sunday. A broad, weak surface trough will extend from the central Plains to the northern Plains. A moist environment will exist ahead of this trough with dewpoints in the upper 60s to low 70s. ...Northern Plains into the Central Plains and Ozarks... A frontal zone is forecast to extend from the northern Plains to the Midwest Sunday morning. South of this boundary, moderate to strong instability is forecast to develop amid upper 60s to low 70s dewpoints. Despite the strong instability along this frontal zone, convective development (particularly strong storm development) remains uncertain given strong height rises expected across the region beneath the building ridge. However, if storms are able to develop, 25 to 30 knots of effective shear should be sufficient for storm organization and perhaps some rotating updrafts. Large hail and damaging winds will be the primary threats. ...West Texas to western Oklahoma... Storms are expected to develop across West Texas Sunday afternoon amid moderate instability. However, very weak mid-level flow will be present across the region which will likely lead to storm mergers and relatively quick upscale growth into a likely non-severe MCS. Given the steep lapse rates across the area, some isolated severe wind gusts may occur, particularly early in storm lifecycles. This potential does not appear large enough for 5 percent probabilities at this time. ..Bentley.. 05/29/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
