CP meaaured 1.89 liquid. Impressive storm.
I can't recall when the 19.7 total was reported, but 0.15 liquid was reported from 1 PM to 4 PM and 0.09 liquid from 2 PM to 4 PM
CP should definitely be over 20...

Sure looks like the low track has had a considerable northern component over the last four hours.
This is free and does the job... lots of customization possible.

If an artic high is very strong, the cutoff can be very tight. I think 2016 was a good example of that. This storm doesn't seem to have that feature. Any mets want to weigh-in?
