Heat waves can significantly increase electricity demand for cooling, potentially impacting natural gas consumption for power generation and influencing energy prices. The juxtaposition of potential cooler waters enhancing onshore flow and a mid-week heat burst suggests a complex near-term weather pattern for the East Coast. Separately, a non-tropical low-pressure system is forecast for the west-central Atlantic.
