El Servicio Meteorológico Nacional advirtió que se espera que una cúpula de calor traiga altas temperaturas y humedad a lo largo del centro y este de Estados Unidos. Según NBC News, el fenómeno podría afectar a alrededor de 111 millones de personas, con máximas diurnas en los 90-100 °F y un índice de calor que alcanzaría los 114 °F. CBS News informó que la ola cubriría más de la mitad del país hasta el fin de semana del Día de la Independencia, con índices de calor de hasta 115 °F en algunas zonas. NPR señaló que se pronostican calor peligroso y alta humedad en la mayor parte del territorio, y los funcionarios de salud instaron a tomar precauciones. CNN indicó que la cúpula de calor elevaría las temperaturas a casi 100 °F y aumentaría la humedad en el Medio Oeste, la región del Atlántico medio y el Noreste, lo que provocó advertencias sanitarias.

El New York Times reportó que el sistema de alta presión persistente podría generar temperaturas de tres cifras y noches inusualmente cálidas desde el Medio Oeste hasta el Noreste durante el fin de semana del 4 de julio. Posteriormente, el mismo medio señaló que los pronósticos instan a las autoridades a abrir centros de refrigeración antes de la festividad. The Weather Channel proyectó que la ola de calor podría romper récords en el Medio Oeste y el Este, afectando a más de 180 millones de personas. BBC estimó que la cúpula traería temperaturas entre 95-105 °F a aproximadamente 120 millones de personas al iniciar el fin de semana festivo. El New York Times añadió que la ola de calor en movimiento se espera que ponga bajo alertas de calor extremo a más de 160 millones de personas, con temperaturas récord anticipadas antes del fin de semana del 4 de julio.
