Thanks Peter!
I've used some of the historic weather websites in the past to "predict"
what the weather may be like during a specific week or month that I had
planned on visiting. Of course, this all has to be taken with a grain of
salt or a voluminous amount of additional weather data!

Interesting side note: My last long cross country trip departed Feb 10 KSTE
(Wisconsin) -KEYW (Key West, FL) Depart KEYW Feb 16 - KSTE 19 hours
hobbs, 1 hour actual IFR = 5.26% IFR. However there were IFR days before,
during, and after.
