Looks like the first half of September may be characterized by high pressure building in this week, FROPA next weekend as the high slides east, followed by another high pressure building in, and then eventually a front. The season is certainly transitioning. In the aggregate we'll probably end up above-average but there will be plenty of cool shots to hold those anomalies in check.
But we'll see what happens...sometimes as we enter the transition seasons the medium/long range can go bonkers and overzealous with these high pressure systems and how much they dominate. Regardless, seeing this on the models is a strong indication the NH is beginning the seasonal transition.
