I think the OP (and I) were wondering why we have to go digging at gov't web sites etc. - usually several clicks down and into the menu
I think the problem here is one of data quantity. For everyone who wants simple snow total from yesterday, there's also someone interested in morning dew points, temps at a given hour of the day, high temps, low temps, daily change in temps, when's the last time it sleeted, well...you get the point. Then the actual forecast and any Watches or Warnings get shuffled off into the abyss known as the internet even though the NWS' main mission is to provide forecasts and warnings for the protection of life and property while enhancing the economy.
Truth be told, I'm somewhat surprised the NWS does as much as it does in record keeping when that is the mission of the old NCDC (National Climatic Data Center), now called NCEI (National Center for Environmental Information). They are the final warehouse for all things climate, which includes yesterday's weather.
And yes, I knew you were putting out a pile of corn when I saw this originally. Like most critters, I just can't resist a free meal.

"
When I grew up snow totals announced the next day seemed ubiquitous. Maybe it's selective memory."
p.s. You also know that those snow reports are the result of the general public calling in to provide measurements, right? The NWS only has two offices in the state, Bismarck and Grand Forks. Outside of those two locations, they are at the mercy of your friends and neighbors calling in snow reports. Many are trained observers, but they aren't paid for their efforts, so getting timely reports is a known limitation. The official Cooperative Observers don't actually have to report but once a month, usually between the 1st and 5th of the following month they send in their reports.
Back when you and I were young, the average farm size was probably right around 1,000 acres. Nowadays that is probably well north of 5,000 ac, so population density in the ag community is falling and they tend to be some of the most diligent weather watchers. So that isn't helping much either nowadays.
