Several factors could shift odds significantly before resolution. Updated seasonal climate forecasts, El Niño or La Niña patterns, and long-range weather models will influence trader positioning. Major atmospheric events—such as a heat dome or unusual jet stream configuration—could trigger sharp repricing.

Real-time weather alerts and any anomalous heat events in the Southwest region may also prompt traders to adjust their positions closer to the event date.
