Isolated severe storms are possible on Thursday over western Montana, northern Idaho, into central Oregon/Washington. ...Synopsis... A broad upper ridge will be present on Thursday over the central U.S., with an upper low over CA and an upper trough over the northeast states. Scattered thunderstorms will affect much of the southeast, southern and central Plains, and northwest regions. ...OR/WA/ID/MT... One area of concern for the potential of severe storms will be across the northern Rockies and Pacific Northwest states. Models depict one or more shortwave troughs rotating around the CA upper low, providing ascent and strengthening wind fields across parts of eastern OR/WA, northern ID, and western MT. Confidence is rising that a zone of sufficient instability/shear will develop to support strong thunderstorms Thursday afternoon. Large hail and damaging winds appear possible with the strongest storms. ..Hart.. 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.
