Here is a couple links that some might find to be interesting. Lately I’ve been working with these sights for the limited fishing times I’ve had this season.
For the weather nuts….. you’ve probably got these dialed in already but, for the rest of us these might be of interest.
They are weather (barometric maps) so you can track weather patterns and pressure systems as they move through…. I wouldn’t go so far as to completely plan your trip around this info… but it might be of use.
The second link is a conversion chart for millibars to HG pressure or vice versa.
Most cat guys can probably agree about, low pressure systems turning on the bite….sometimes in a big way.
