A few strong storms may occur over parts of the Carolinas, and perhaps from western Montana into eastern Washington. ...Synopsis... An upper low will gradually weaken as it moves very slowly from CA into NV on Thursday, with a belt of stronger mid to high level winds from UT into ID, WA and OR, where minor height falls are expected late. To the east, weak upper ridging will remain over the Plains, with weak winds aloft. Meanwhile, an upper trough will move out of the Mid Atlantic, with weakening northwest flow over the Carolinas. At the surface, moisture will remain abundant from TX into the Southeast, south of a cold front extending roughly from parts of the mid/upper MS Valley to SC. This boundary will provide a focus for afternoon thunderstorms from NC into SC, but both shear and instability are forecast to remain marginal. To the west, weak low pressure will develop during the day from eastern WA into MT with strong heating. Forecast instability is a bit uncertain this far out given the pattern, though some models indicate hail potential should sufficient moisture develop into the region. Deep layer shear will be favorable for cellular development, but perhaps a bit south of where the greater thunderstorm probabilities are. Given these uncertainties, will defer to later outlook updates regarding any marginal risk potential in the eastern WA, northern ID, and western MT area. ..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.
