Notice the latest jogs back to the west for four of the models which at one time were showing a north progression up the east coast.
Those all happened on last night's 2AM EDT model runs. They should post the 8AM model runs shortly.
Jeff Masters has been commenting that an upper level low has been stuck over the Eastern US for weeks, and has resulted in the jet stream recurving systems northward quite early in their travels to the west. But he's repeatedly said that an upper level high is expected to replace the low, probably by tomorrow. That is expected to delay recurvature by pushing systems to the south and allowing them to continue their westward travels. He's been specific that this means systems are more likely to get into the gulf. See his 8/13 blog at www.wunderground.com/blogs.
So, it looks to me like the 2AM model runs now expect the arrival of the high pressure ridge and the resulting shift in the jet stream. Not what we'd like to see.
Thanks! I will and have a few times in the past. To be honest with you, I always check the storm threads on here, but usually don't have much to add since the other projections are pretty similar to the one I get. I will throw in my "buffalo nickel" when I see something that is different.
