weather forecasting – A new film, Pressure, casts Andrew Scott as WWII meteorologist James Stagg and centers the weather forecast that helped determine whether D-Day would proceed on June 5 or be delayed—an episode that could have turned an invasion into disaster.
If you imagine D-Day going the way it was first set, it’s not the ships that decide the outcome. It’s the forecast.
In June 1944, the largest seaborne invasion in history was planned for June 5. But without a weather forecast. the invasion would have happened as scheduled—and the account that follows is stark: thousands of men would have been swamped by storm-whipped waves. turning an operation into a catastrophe. Allied forces waited a day instead. The delay changed everything, and what followed is history.
Yet for all the retellings of World War II’s pivotal battle—across books. movies and miniseries—the crucial ingredient behind that single. consequential decision has stayed oddly out of the spotlight. The forecast itself, the prediction that made leaders pause, remains little known to the broad public.
That gap is at the heart of Pressure. a new movie that stars Andrew Scott as World War II meteorologist James Stagg. The film explores the crucial role weather forecasting played in D-Day. asking viewers to focus on a different kind of expertise: not strategy on a map. but the reading of the atmosphere in the days before modern tools.
Scott learned all about meteorology for the role. In a conversation with senior desk editor Andrea Thompson. he discussed WWII. meteorology. and the challenges of analog weather forecasting in the 1940s—when the work depended on methods that weren’t built for the kind of precision people often expect today.
The premise is cinematic, but the stakes it points to are historical and immediate: on June 5, the plan was in motion; with storm conditions looming, the forecast was the hinge. Waiting one day kept Allied forces from walking into disaster, and it redirected the entire trajectory of the invasion.
Pressure also lands on a familiar tension—how hard it is for the public to recognize the science behind turning points. D-Day’s story is widely told, but the forecast that helped determine the timing is still easy to overlook. In the film. Scott plays a meteorologist who doesn’t just interpret the weather; he represents the people whose work can decide whether thousands sail into violence or hold back long enough for the moment to change.

So it was basically the weather guy that saved the day? Wild.
I feel like everyone always skips the boring science parts, but the forecast literally decided whether people died?? How is that not common knowledge already. Also Pressure looks like it’ll be pretty intense.
Wait, I thought D-Day was delayed because of equipment issues or something, not weather predictions. Like if they didn’t have a forecast then why would it even be scheduled in the first place? Idk, movies make it sound too simple.
Andrew Scott as a meteorologist sounds oddly perfect but also I’m like… how accurate were they back then without modern tools? They really just guessed and hoped? Yet the whole invasion hinged on it, so I guess their analog methods were secretly super legit. I just wish they’d show more of the actual forecasting part instead of only the dramatic decisions.
