While it will likely be a wet one, beloved mainstay balloons like Snoopy and Pikachu — and newcomers like Minnie Mouse, Gabby from “Gabby’s Dollhouse” and Spider-Man — should be just fine to fly given the current forecast.

Forecasters say the rain could begin as early as Wednesday night or slightly before daybreak and carry on into the morning Thursday, conditions that could also spell difficulty on the roads and at airports on the big travel holiday. Thursday's high temperature is expected to peak at about 50 degrees.
