clouds will form at a given altitude, reflecting solar radiation. This  will 
result in a lowering of the temperature. I haven't yet determined the exact  
limit conditions, but it would seem that (very roughly), you can obtain 100% RH 
 only if the temperature is under about 15°C. At 25°C, the max humidity is 
~85%.  At 35°C, 75%. At 50°C, 55%.

I have seen several days of temperature in the 90-100 F range and humidity  
of 95% and higher, particularly in Texas and Louisiana.  I do not know  where 
the limit is, but I have seen reported humidity by local weather of  102%.
