The weather data PDFs on the Fundamentals CD (packaged with the print 
volume) includes 20 and 50 year return period extreme dry bulb temps.  
On the CD, look in the folder DATA_TABLES_FOR_STATIONS folder.  There is 
also a map-based station finder.

A wealth of additional info can be derived with the WDView 5.0 product 
sold by the ASHRAE Bookstore.  Everyone should have a copy of that.
