Thunderstorms are unlikely tonight. ...01z Update... Dry, mostly stable conditions are noted across the lower 48 early this evening.

It remains a bit unclear how emerging waves will impact the downstream pattern by the middle to latter portion of next week. However, it still appears that one significant preceding short wave trough, migrating inland of the Pacific coast by early Monday, will progress into and across the southern
