I preach the virtues of weather.gov to anyone who will listen. All weather, no bullshit. No obnoxious "reality" content, no garbage ads, no clickbait, no auto playing video... It's a more pleasant experience than certain other weather sites even with ad blockers enabled.

It really doesn't. That link you provided shows plenty of winters under 30 inches for a season throughout the years. The average is 44 inches so that means half of winters should have more than that, and about half of them should have less of that.

NON-EXPERT OBSERVATION. Back when Doppler radar imagery online was new (1990's) the opposite was true: there was frequently a lot of signal in the town itself, but not outside it [this was when I lived in Texas] Later, signal processing methods appear to have been developed to reduce radar "clutter" in Doppler imagery which arises from the landscape and not the atmosphere. https://ieeexplore.ieee.org/document/1460942

So we may be looking at an artifact of "subtracting" baseline noise from the radar return over the city. During those years in Texas, if I really wanted to see what was happening in our city, I had to examine the radar result coming from a different radar station in another city.

not really. what most people don't think of is that weather is 3D, rather than a plot of rain and snow on a 2D map. layers of warmer and colder air in the upper atmosphere are far more pertinent to what precip you see at ground level than anything happening on the surface. that's not to say small variations caused by local microclimates don't make a difference in observable weather, rather that they aren't going to change the whole metro area's weather like this dry slot did.

urban heat island wouldn't really have much impact until the snow is below radar levels anyways. snow might stick less downtown or vary slightly with elevation, but most of the dynamic weather is happening far enough up in the atmosphere to render small changes in what precip looks like at the surface moot.

Same. Every day it's "we need 7 volunteers to stay home today and pay us", which I get, I guess, but they had this teed up at like 6PM yesterday so you know they were salivating over it.

Edit: I creeped through your post history. Pretty sure our kids know each other haha. You're basically me.
