NEW DELHI, July 26 — How does a weather forecast for Shimla or Kolkata actually get made in 2026? A disclosure tucked into a recent publication from the Indian news platform LatestLY offers a clear, honest answer: a careful partnership between machine and human. The forecasts, published on July 27 at 12:06 AM IST, carry a disclaimer stating that AI tools assisted in compiling foundational data and research, with the final content reviewed, edited, and verified by human editors.
It is a modern, transparent admission of how the sausage is made — and it points to a broader shift in the science of weather prediction.
AI and the Data Deluge
The core mechanism is straightforward. AI can now analyse vast datasets streaming in from satellites, weather radars, and numerical weather models. Where a human meteorologist might struggle to process the sheer volume of information, a machine can identify patterns and generate predictions rapidly.
These are the same kinds of deep-learning models that have been improving short-term forecasts in recent years. What researchers have found is that these models are particularly good at spotting subtle signals in noisy data — a shift in wind shear, a change in humidity gradients — that might escape a traditional computer model.
The science behind this involves training neural networks on historical weather records, letting them learn the statistical relationships between different atmospheric variables.
The Human Touch
Intriguingly, the LatestLY disclaimer makes clear that the machine does not have the final word. Human editors check the AI’s output for accuracy, add context, and filter out anything that looks off. This is not a fully automated forecast; it is a hybrid system designed to harness the speed of the computer while leaning on human judgment for nuance and verification.
That oversight matters. Weather forecasting has evolved dramatically since the early 20th century, when predictions relied almost entirely on simple observation — a barometer reading, a glance at the sky, the feel of the wind.
The leap to numerical weather prediction, using computers to solve the equations of atmospheric physics, was a revolution. Now, artificial intelligence offers a further step, but the human role has not vanished. At LatestLY, the process highlights both the efficiency gains and the potential for error reduction that AI brings, while insisting on a final layer of editorial control.
From Observation to Prediction
This is the story of a technology that is no longer experimental. Deep learning models are already operational in many forecasting centres around the world, producing hourly updates that would have been unthinkable a generation ago. But as the latest forecasts from Shimla and Kolkata remind us, the old virtues — checking a number, questioning an anomaly — remain central to the craft.
What to watch next? As these AI-assisted systems become more common, the question will be how much of the human oversight can — or should — be automated away.
For now, the balance is clear: the machine crunches the data, and the editor signs off. That is how a 2026 forecast gets made.
