OK, well I guess it was good while lasted.
In my case, my AcuRite station does not forward the precip rate to WU, only the running precip accum/total. The WU ‘precip accum’ is what was populating to PWSWeather as the ‘daily precip total’ - until recently. Sounds like they may be making changes. FWIW here is my data from 4/28:
From your screenprint, it sounds like WU is no longer providing the ‘precip accum’ (which is why it is not forwarding to PWS), but in your case it looks like it is crossing your values. Weird.
