Between 168hr and 192hr on this 00z Euro run, something very strange happened. Keep an eye up near Halifax, Canada.


0z Euro: low pressure appears at 24 hours 1007mb | 24-48 moves W 1003mb | 48-72 moves NE 997mb | 72-96 moves N 989mb | 96-120 moves S 983mb | 120-144 moves NW 971mb | 144-168 moves W 953mb | 168-192 moves NE 930mb | 192-216 inland, moving NE and weakening
A rather strong 1027mb high pressure near Nova Scotia is replaced by a 996mb non-tropical low pressure area. It yanks Katia to the NNE, sparing Bermuda a direct hit, and it also seems to be the catalyst for Lee pulling northeastward into Louisiana and then catching the trough that enters the CONUS (which it would otherwise miss as it heads towards STX/MX on the previous runs) Where's that low come from? It feels like a "Glitch in the Matrix" to me, and I'm inclined to throw this run out despite how exciting it might be.
