Just to reiterate my point from my last point, 3 runs showing the ridge at around 192hrs and the low to the east of America...
First is the 00z, 2nd is the 18z and the 3rd is the 12z they are at different times and a day either side, but its a trend IMO, which i will be looking out for.
Edit:Looking at yesterdays runs, they all show similar trends around these timeframes..
