I've been a broadcast meteorologist on television since the early 1990's. Happy to answer any questions about the weather or local TV news. Yes, I often wear sneakers on set just out of view of the camera.
We use the weather forecast models and the other tools mentioned in your other question to generate a forecast and then use television, radio and social media to share information.
I usually answer this questions like this. I really don't like the use of the word "normal" in weather. "Average" is better. Over simplified, if the "normal temperature for this date is 75 degrees and we look a the records for the last 100 years. In theory half of those years the temperature could have been 50 degrees and half 100 degrees. The "normal" is 75 but it was never 75. So, there are swings in the global weather patterns constantly you're at one end of the swing! Hope that makes sense.
Hi, Reyna. Standard anemometer height is 10 meters.
No problem. Thanks for the information. It could be that a local weather source is using that term. “Officially” the term used by the National Weather Service is a tornado warning, and in some extreme situations a tornado emergency. Thanks again!

How do you feel about magicians on TV who reveal how tricks are done?

Are IRS auditors more accommodating when you're polite with them?

Interesting question. A little out of my area as a local meteorologist. You might have some luck looking around the website for National Center for Atmospheric Research. https://ncar.ucar.edu/
Yes. But some would disagree.
Complicated answer, Richard, but a good question. There are quite a few and I really can't give a number off the top of my head. Easily more than a dozen It is complicated because different models offer different solutions. Some are short range, some are longer range. Some are US based, others European and Canada and Japan. To further complicate the issue some models are run as "ensembles" meaning they are run from the basic initial data but small variations are introduced to give different solutions. The basic input data is collected twice a day from about 900 upper air sites, or weather balloons, launched twice a day, noon and midnight Greenwich mean time. The idea is to take a snapshot of the entire planet atmosphere at the same time. Also, more and more data, from satellites and radar for example, is now ingested into the models to varying degrees. A shorter answer is, on a regular day I'll look at three or four.
