WOW ! one thread that addressed a few  questions for me.

I will pay much more attention to the fronts that are constantly moving through mid MO.

My wife injured her knee a while back and when the weather changes, her knee hurts. And I have an ankle I sprained really bad that acts up.

Can't see the jet trails 'cause I don't think many fly over where I'm at.

I won't let her know this though, I'm afraid if she knew that she was an indicator, she wouldn't let me know her knee hurt  

Wives, geezzzz that could be an entire new thread if not a board  ;D ;D

My wife don't have any problem with me fishing, but she thinks I have a mental problem this winter because my work is slow now and if I'm not fishing I'm thinking about it or sitting hear learning more about it.

Kudos to you who have wives that will go with and sorry for those of us who have had injured wives.

There are lots of weather related reasons why this is true but I will not bore you with them here--just get out there when the contrails are in the sky and mow the lawn later.

Please, bore us!

Most people who enjoy the outdoors realize wildlife and fish are on the move prior to a quick change in the weather. The animals and fish have a built in survival mode realizing a meal may be difficult to get tomorrow. For deer, elk, turkeys, ect, they somehow know they need extra food to get thru the bad weather coming. Bass are the same as the food chain grinds to a halt with a passing spring cold front (these reasons can be debated later). My wife even knows when there is an approaching front as after her leg surgery her leg throbs. She is also a great indicator of an approaching cold front and when to go fishing.

The simple explanation for the jet contrails indicating an approaching cold front is that the high level winds may be moving at over 100mph. This causes whatever is to the west/northwest (exceptions on the east, and gulf coast) to show up in the upper atmosphere first. What this means is if there is a spring cold front approaching there normally will be moisture associated with the front. This high altitude moisture will be blown ahead of the front 24 to as much as 48 hrs depending of course on the speed of the front. With this high level moisture (even unseen) when a jet flys thru the frozen ice particles they get heated and turn into a visible vapor. Again, all the contrails indicate is high level moisture, and high level moisture is normally only in the upper atmosphere in the U.S. in a prefrontal condition. As the front gets closer you will normally see cirrus clouds which look like whispy "horse tails." As the front gets close you should expect to see thunderheads on the horizon. If we agree fish are more active in prefrontal conditions in the spring, contrails means it is time to fish.This is more accurate than the Channel 12 weatherman.

I talked to the owner of Lake Fork Taxidermy about weather and catching fish. He said when the anglers would bring a photo of the trophy to get the proper coloration, they would most always be wearing their rain gear in the photo. Maybe not raining but they had it on. Interesting.

On Tom Reddington's photo of the 10+ lb bass in Feb he said he got hailed on. It had been in the upper 60's, as fast and violent cold front approached, he got his 10lbr. Tornados everywhere and an ice storm followed. What a day.

When there are jet contrails in the sky I am either making them or in my boat watching them.

That is some interseting info for sure.
