The western US trough will shift southward into the Great Basin on D4/Wednesday with strengthening westerly flow overspreading the southwestern US. The axis of the central US ridge will shift eastward, with heights continuing to rise across portions of the central/northern Plains. A few stronger storms may be possible across portions of central/eastern Montana. Overall, confidence is low in any areas of organized severe potential. Widely scattered thunderstorm activity will be possible from the Southern/Central Plains to the southeastern US. Generally weak flow should keep organized severe potential low. The exception may be across far western Texas where modest mid-level flow will continue, though large scale forcing for ascent will decrease from D3/Tuesday. For the D5/Thursday through D6/Friday period, ensemble guidance suggests the western low will shift northward again and phase with the northern jet stream. There is low confidence in chances for strong to severe storms, pending details on moisture, across the northern Rockies into the central/northern high Plains as lee troughing strengthens. Some severe potential may also extend into the eastern and southeastern US as a cold front shifts southward as flow enhances in the trough across Quebec from D6/Friday to D7/Saturday. ..Thornton.. 05/24/2026 = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
