I am watching Katia closely. Lee is affecting the weakness in the ridge that was forecast to allow Katia to make it's northward turn, slowing the eastward progression of the weakness. Long range GFS models are now showing the weakness closing before Katia reaches it. A new weakness is shown forming shortly before Katia reaches the east coast, but I question the strength of that weakness given that it is not being driven by a frontal zone - it looks like the GFS is overpowering the decay of the ridge.
If you are anywhere from North Carolina through Canada, keep a close eye on Katia. The likelihood that it will re-curve before reaching the US is decreasing. Right now long range models are showing a re-curve just off the US coast and impacting only Prince Edward Island, but only a slight change in timing or course could cause it to hit the US.
