Metars history 
Normally 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 %) much slower.
Indeed, 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.
When comparing historic Tdry / Tdew / cloudbase, remember hotspots locally Tdry might have been 1 higher and Tdew 1 lower, but useful cross check.
