past 24 hours is very quick but when a different resource has to be used
for 'past 120 hours' (also 'past 24' where indicated by %)
they often don't work at all.
You might be able go back
more than 120 hours to eg 240 (10 days) by changing the url to 240 but
it then becomes very slow indeed.
comparing historic Tdry / Tdew / cloudbase, remember hotspots locally Tdry
might have been 1° higher and Tdew 1° lower, but useful cross check.
