PWS Numbers

I switched to a PWS yesterday morning. 2 questions

  1. numbers from machine say 0.24, but moisture graph says 0.17. Why the difference?
  2. why is yesterday August 10th still listed as forecasted in moisture graph when it’s now like 11am est, 8am local on August 11th

Aug 10 is now not listed as forecasted but the numbers still do not equal the number listed on the PWS. Now it’s showing 0.19
