The report says light showers are more likely than a prolonged downpour, making a poncho more useful than a major change to matchday plans. Conditions are also expected to improve by early evening as the rain eases.
That matters for both teams and supporters. A damp surface can affect footing, passing speed and the tempo of the game, while wet concourses and queues may create the bigger inconvenience outside the stadium.
Thunderstorms have not been ruled out entirely. However, the report says they are considered unlikely in the area. If lightning does develop, stadium safety procedures could require a pause in play and the movement of supporters to shelter.
The more serious weather storyline begins next week. The report forecasts temperatures in the mid-to-upper 90s on Wednesday and Thursday, with humidity pushing the heat index above 100F.
Those conditions would create a sharper test for training sessions, fan events and anyone spending long periods outdoors. Hydration, shade and indoor breaks would become central to preparations, particularly for children, older supporters and people unused to North Jersey’s summer humidity.
The report also says the hot spell could continue into the start of the Fourth of July weekend, while scattered afternoon showers or thunderstorms may return later in the week.
For Friday, the forecast points to a playable World Cup occasion with rain as the main variable and a low storm threat. The next key checkpoint will be the final update before kickoff, while clubs and organisers will already be watching Wednesday and Thursday as the more demanding weather days.
