Jeppesen has a free weather service C-Weather, it's a 5 day forecast for any area 180 miles by 180 miles you choose and it's updated each day. Need a Internet connection to get and load on card, then my Standard Horizon cp590 displays the information. It's available I believe for any plotter that uses the NT+ or Max cards that have the software to support it. My cp590 and cp300i will my cp500 will not, I have never checked if SH has a software update that would allow it to. I have not used it yet but plan on it this year.

I don't like making plans for the day because the word "premeditated" gets thrown around in the courtroom.
