Major atmospheric patterns—such as heat domes, cold fronts, or tropical moisture intrusions—can reprrice the market significantly. Historical May temperature records and anomalies in spring warming trends provide context. Urban heat island effects and local weather station data also matter. As May approaches, medium-range forecasts become more reliable, typically causing sharper price moves. Real-time weather alerts, El Niño or La Niña developments, and any unusual atmospheric blocking patterns in late spring will drive trading activity and odds adjustments.
