A weatherman predicting rain has made a falsifiable prediction, how does that relate to Popper?

Everyone’s just using models here, and the way we incorporate statistical observations to define the limits of the models’ scope, and refine the models over time, or reject the models entirely, applies to economists, meteorologists, seismologists, and many branches of actual human medicine.
Popper would define pseudoscience as predictions that can’t be falsified, but surely that can’t apply to the idea of the weatherman predicting rain and being wrong, right?
Kuhn came along and argued that science is about solving problems within paradigms, and sometimes rejecting paradigms in scientific revolutions (geocentrism vs heliocentrism, Newtonian physics versus Einstein’s relativity), but it wasn’t a particularly robust test for separating out pseudoscience.
Lakatos categorized things further at explaining how model-breaking observations could be handled within the structure of how science performs its work (limiting the scope of the model, expanding the complexity of the model to fit the new observations, proposing specific exception handlers), but also observed the difference between the hard core of a discipline, in which attempts at refutation were not tolerated, and auxiliary hypotheses where the scientists were free to test their ideas for falsifiability.
But when you use these ideas to try to understand how science works, I don’t think economics really stands out as less scientific than cancer research or climatology or other statistically driven scientific disciplines.

how does that relate to Popper?
When a weatherman’s prediction is falsified, the model itself is not disproven. The fact that the practitioners of that discipline stick with it even when a prediction is falsified starts to look like the pseudoscience side of Popper’s falsifiability criterion.

To quote the order commenter here, basic foundational “observations” by Economics aren’t based on the Scientific Method.

In what way? And how does that differ from how medicine measures pain?

There are several physical autonomic responses that demonstrate feeling pain that can be measured

Namely, the scientific method relies on inductive reasoning and foundational economics relies heavily on deductive reasoning.
The difference isn’t the data itself, it’s what they actually do with it. Medicine takes subjective, self-reported pain scales and plugs them directly into rigorous, double-blind, randomized controlled trials where they isolate variables to test a strictly falsifiable hypothesis.
Foundational economics, on the other hand, takes subjective concepts like “utility” or “rational self-interest” and uses them as unfalsifiable, deductive assumptions to guess how massive, open systems work.
Basically, you can put a new painkiller in a placebo-controlled trial to scientifically prove if it reduces that subjective pain, but you can’t put a macroeconomy in a petri dish to run a controlled, repeatable experiment on supply and demand.

Plenty of medical science doesn’t lend itself well to double blind studies. In vivo infection models can’t ethically be tested with double blind studies, and can only be observed. Lots of medicine advances through observational studies, too, like almost anything relating to nutrition or lifestyle or trauma. There’s no double blind study on how survivable car accidents are.
Plus double blind studies themselves don’t necessarily have any kind of explanatory power (see the entire field of anesthesia where we know how much of each anesthetic it generally takes to put people under, but we don’t know the underlying mechanism it uses to make people go under). Or, for that matter, Tylenol (whose mechanism of action remains a mystery).
