Prepare for bad weather with things like portable heaters and ponchos, and have a plan to move the event inside if needed.

Prep your store to have double coverage on Fridays and Saturdays as a standard practice to prepare your staff to work during peak event times.

Use a calendar app to block off time visible to your staff, so they know the event is coming.

If you are crunched for staff, look outside of your company to see if you can find somebody to hire for that event to help focus on driving traffic and engagement at the event.
