Idk if the almanac can predict that far but I know for boone nc typically the high is in the low 70s can be anything 60-80 on average and the low is usually about 50 can be anywhere 39-60 fall foilage may have started on an abnormally cold year and rain is 50/50 snow is impossible until september for boone. Chances are it'll be a nice day but maybe bring sweater for night time

The Oracle has Spoken

Predicting weather, down to the day

Not sure if some of you have EVER used an Almanac in the past?!
Just ant FYI, it's NOT a fortune teller !


Some of these questions are asking specifically about a single day- does the almanac actually predict down to the day and even time of day like some of these questions are asking? Or is that as nutty as it seems to ask?

Halloween Wedding

My daughter is getting married on Halloween this year and wants to have the ceremony outside here in Charles Town, WV. Will the weather permit or should we plan on an inside ceremony?
