I hadn't thought this through much before but it might make a difference so I thought I'd ask. Let's say you are looking at a 1h model output valid for 12Z, is the 1hour precip the total accumulated precip between 11Z and 12Z? And if it is, then shouldn't we compare the 12Z precip charts to the 11:30Z radar rather than the 12Z radar?
2024/2025 Snow days (approx 850hpa temp): Total: 2 days with snow/sleet falling
18/11 (-6), 19/11 (-6)
2023/2024 Snow days (approx 850hpa temp): Total: 8 days with snow/sleet falling
29/11 (-6), 30/11 (-6), 02/12 (-5), 03/12 (-5), 04/12 (-3), 16/01 (-3), 18/01 (-8), 08/02 (-5)
2022/2023 Snow days (approx 850hpa temp): Total: 7 days with snow/sleet falling.
18/12 (-1), 06/03 (-6), 08/03 (-8), 09/03 (-6), 10/03 (-8), 11/03 (-5), 14/03 (-6)
2021/2022 Snow days (approx 850hpa temp): Total: 12 days with snow/sleet falling.
26/11 (-5), 27/11 (-7), 28/11 (-6), 02/12 (-6), 06/01 (-5), 07/01 (-6), 06/02 (-5), 19/02 (-5), 24/02 (-7), 30/03 (-7), 31/03 (-8), 01/04 (-8)

(That's one of the reasons I pay for the NW radar, you can set it to show precipitation totals over 1 hour, 12 hours, 24 hours etc).

They have a radar accumulation tool.

Here's the specific page. They allow custom colorscales too.
Can't believe I never thought of doing this.

There is a free to access rain total API provided by the government IIRC.
