Our daughters wedding is August 18 scheduled for outside at 6pm. What is the prediction about the weather? Charlotte NC

Outside wedding

What is the weather going to be like on October 13th planning and outside wedding


I am so sorry, I wish it could be bluebells and butterflys. But the truth is it will rain, with it taping off in the evening. Make plans for doing it indoors if it continuse to rain. I'm sorry.....


You should of ask for a specific time also. In NC you better have a back up plan with how the thunderstorms just pop up. One thing is for sure you are going to BURN UP and so are your guest. Have lots of ice available.

It is kinda comical to read some of these comments and questions regarding a specific date. How about this you can probably count on this maybe just maybe it may be cold January or it may rain in October?!?! Lol How about you have a backup plan just in case the weather doesn't work out in your favor on "your" day?? Make it fun if it rains go with it dance in the rain, if it's hot bring along water balloons, best thing to do is just enjoy life no matter what is happening outside!!

There are some very simple

There are some very simple people on this comment thread....


You guys. The whole point of this is to give folks a general idea of what the weather SHOULD be like seasonally. For all those asking about one specific date in the future- you might as well ask a psychic (sound silly? It should). Use your best judgment, how the weather usually tends to be during that time of year, and keep up with local weather forecasts as your date approaches. It’s honestly the best you can do; weather is fickle, especially here in the southeast.
