Here is the height of the storm on the GFS. It shows mixing in the LSV, but no plain rain in PA.
The WB maps do split out Sleet & Freezing Rain separately, so they are Not lumped in with snow totals.
Who knows which service is better or more accurate?
I pay my 27.99 per month to Weatherbell. They have a lot a commercial clients & 2 seasoned pro Mets that run the website.
I don’t think they would be in business with bad maps…
