The risk for severe thunderstorms appears negligible across the U.S. Saturday through Saturday night. ....Discussion... Models still indicate that the higher latitude western North American mid/upper ridging will continue to weaken and begin to lose amplitude during this period. As this occurs, downstream flow is forecast to back from a northerly to northwesterly component across the Canadian Prairies and northern U.S. Great Plains, in the wake of large-scale troughing receding into the Northeast and eastern Canadian Provinces. However, as mid-level troughing within a separate branch of westerlies only slowly pivots southeastward near the Southwestern international border, cold surface ridging likely will be maintained beneath confluent flow east of the southern Rockies into the Ohio Valley and Southeast. Aside from a lingering risk for weak thunderstorm activity near lower Texas coastal areas early Saturday, and some continuing risk for lightning in low-topped lake-effect convective bands near Lakes Erie and Ontario, the risk for thunderstorms appears negligible across much of the remainder of the U.S. through 12Z Sunday and beyond. ...Kerr.. 11/17/2022 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
