Add a dot for the value for each moth (data are for each month, not continuous).
Month label on x axis: what is standard - numbering the months or using Jan, Feb, March, etc.? I'm partial to the names of the month, angled 45 but best to try and be consistent with other articles in the journal
is it possible for precip figure to be of means with lines for historical min and max for each month like the temp graph? Maybe using the BDFFP data?
1 and 2 are an easy fix, 3 requires using a different dataset. I'll consider after remembering why I decided to go with pre-computed normals in the first place.
