'High goofies' is an alternative to 'High winds', derivative of the well-known Disney character Goofy ('goofies' being the plural). The character is generally associated with the wind, so any mention of him during weather talk refers to that.
EXAMPLE 1
Weather Reporter: "We'll be experiencing high goofies today, so hold on tightly to your hats!"
EXAMPLE 2
Friend: "There is a lot of goofy around here... You should put on a coat."
