Don’t bother — not updated for years!

Won’t run with Mac OS X Sierra.
Apple provides regular beta updates before a new OS to allow competent and consciencious developers to update their apps in plenty of time for the OS release. Apparently Weather Network couldn’t care less about Mac Users.
Their website is a network hog and data sucker, so that’s not an alternative. Guess it is time to give up on their Mac support.
They don’t seem to have a problem keeping their IOS app current, so go figure.
