Scattered strong storms are expected primarily over parts of Virginia and Maryland Wednesday afternoon and early evening. A few damaging gusts will be possible. ...Synopsis... Height falls will occur over the northeastern states on Wednesday as a positive-tilt upper trough moves across the Great Lakes and toward the Mid Atlantic. This will flatten the upper ridge over the Southeast, with increasing westerlies aloft. At the surface, a trough will develop from southern New England into eastern VA, with strong daytime heating. Dewpoints in the upper 60s F will be common, aiding instability. Elsewhere, a deep upper low will be nearly stationary from central CA into western NV, with a surface trough developing during the afternoon from UT into southern ID and eastern OR. Strong heating within this trough may yield scattered thunderstorms moving northwestward across parts of ID into OR, with locally gusty winds. Farther north, instability may develop over WI and vicinity, near a southwestward-moving cold front and on the back side of the upper trough. Isolated strong cells cannot be ruled out with gusty winds. ...Mid Atlantic Region... Scattered thunderstorms may be ongoing across parts of IN/OH/PA within a warm advection zone with westerly 850 mb winds. This activity will generally shift east/southeast during the day, as the air mass ahead of it destabilizes. Possible outflow from this activity, as well as surface convergence within the heating air mass should yield additional cells/clusters during the afternoon, moving east/southeast across VA, MD, and northern NC. Though lapse rates aloft will not be particularly steep, high PWAT along with peak heating and increasing winds aloft will support storm longevity, with possible forward-propagating clusters. Increasing deep-layer shear may also support cellular storm mode. A few strong to severe wind gusts appear most likely during the late afternoon and early evening. ..Jewell.. 05/26/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
