Colby,
Thanks for reaching out to us via the
WSUP viewer forum.
I've attached the NBM v4.1 PQPF
thresholds currently being provided for display in WSUP. The
0.10" threshold in ProbQPF24 was dropped from NBM v4.1 .
0.01" for NBM v4.1 can be found under QMD PoP24.
If you need more thresholds added, I
suggest talking to the team in your region that handles NBM
requirements for future releases.

Under the Probabilities of Specific Amounts (%) section of the
WSUP viewer, the scale for ProbQPF24 in NBM4.0 has values of
0.01", 0.10", 0.25" and so on. The scale for
ProbQPF24 in NBM4.1 starts with 0.25" and goes up from
there. Can the NBM4.1 ProbQPF24 include the probabilities
for 0.01" and 0.10"? Can these also be included
in the scale for ProbQPF48 and ProbQPF72? This would help
with messaging in instances where there is a high
probability it's going to rain, but timing uncertainty of a
storm system is keeping the probabilities in ProbQPF6,
ProbQPF12 and ProbQPF24 lower. This is important for fire
weather across much of the western US and when we are coming
out of extended dry streaks that are receiving a lot of media
attention. Thank you for the help.
