During our upcoming below-average pattern, we're going to see some pretty strong ridging develop across the western U.S. which is going to be rather persistent and this is going to yield some decent warmth at 850mb. There seems to be strong consensus (with teleconnection support) that we will see ridging build across much of the CONUS moving towards the end of the month into September. Perhaps not Sonoran heat release type stuff, but much of that warmer air would propagate and advect into our area and the flow would keep this constant. Not only should it be quite warm but I think we'll also be dealing with high humidity too.
