Our local TV station weatherman has a YouTube channel[1] where he geeks out every morning about the weather, providing a much more detailed forecast than he has time for during the brief windows he has on the TV news. Walks through the HRRR, NAM, GFS, satellite pictures, and other sources of information. It's a nice compromise if you find the raw data to be overwhelming.
There's no substitute for a local meteorologist who knows how weather patterns work in your region and knows how to interpret the models and is good at communicating that to regular people.
Absolutely. It is something that I find amusing about people moving from California, LA/SoCal in particular, where their weather is basically just a nice segue from celebrity talk into more celebrity talk that reads some report the producers pulled. Then, they move to town and are amazed at how much people actually pay attention to the weather and comment on how many people actively have open tabs with the live radar. I usually reply with when you need to know if your ride to Oz is coming or not, you pay a lot closer attention.
It means "tornado," referencing the 1939 film "The Wizard of Oz." The Kansan protagonist is transported by a sudden tornado to a magical land called Oz.
With snow in particular, 20 miles can be the difference between sort of a nothingburger and you really don't want to leave the house if you don't need to.
