It can be done....and, yes, you're screwed
Can you do any of the cooking ahead of time? If so, you may want to try and get the butts out of the way first and just save the ribs for the last minute/day of cook. How many butts, how many racks of ribs?
Lastly, you can start the cook on Friday night/saturday morning and after about 6-7 hours of smoke on the butts, you can put them (gasp!) in the oven. They'll have a good amount of smoke flavor and you don't have to fight with the wind and temps. If you are comfortable with the electric option, that's a whole other story.....
