Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
"The Weather" Effect Monsters in your Main Monster Zones of this card's column and its adjacent columns gain this effect. ● You can banish this card, then target 1 face-up monster on the field (except during the Damage Step) (Quick Effect); halve its current ATK for the rest of this turn, but it can attack directly this turn. You can only control 1 "The Weather Cloudy Canvas".
