While yesterday's rain total isn't exactly a current condition, I would 
like to have the display page show the amount of rain from yesterday.

I know there are different ideas on when rain totals should zero out, but 
I'm asking for something slightly different, and for me, would add to the 
usefulness.

I'm thinking of the situation that often occurs when a storm series moves 
through, with say 1/2" or so of rain before midnight, then even more after 
midnight, say 1/4" in the new day.

It is really all the same storm, and not worth the logic to have it done 
automatically, but to glance at the summary page and see today's rain is 
1/4", when the storm total is 3/4" would really work better to list what 
yesterday's rain was right after today's total so far.

I don't know how the inner structure of WeeWx works, so one way would be, 
if the variable is available, to have today's rain total saved at midnight 
to a new variable called YesterdayRain, then zero the today's rain 
variable.  It seems simple,but I don't know if the ordinary user would have 
the ability to modify WeeWx to make this work.

Is there already this Yesterday's Rain value available, and if so by what 
name? 

Can we add a display line to the skin that generates the standard page, or 
not?

Another way to do it would be have the database total up yesterdays rain 
with a date range but this seems to be a lot of work, involve accessing the 
data base for no added reason, if one just had the YesterdaysRain already 
stored.

Just some thoughts. So far this is the only tweak I've thought of that 
WeeWx doesn't seem to already do.  Python is really beyond my current 
skills, and while I know some might whip this together in short order with 
their programming knowledge, I don't know how to find the stored variables 
already, or fiddle around with it and screw something up.
