Sorry but.... Wrong.

Yea I would be great if winter was like this, but it's January 18th and 51°f outside and we haven't had snow scince Christmas, and even then it wasn't much. Interesting prediction but incorrect, mabey next year.

Wrong...

Dear "sorry but wrong",
Look out your window.
Sincerely,

Horrible hot summer like usual in Grand Junction Colorado

It is always miserable here in the summer. Long time resident here. But that’s why it’s cheaper to live than nice areas of Colorado. Harsh summers and winters with freezing temperatures and inversions. When people say they moved here for the weather, I know they are misinformed or moved from hell.
