Have you considered a trainer for excessively windy days? My wind trainer gave up the ghost last winter, and I got a fluid trainer. Fluid is much better; I even found it to be fun. You can get a direct-drive trainer as low as $329.
I'm in an urban/suburban area, and I don't feel safe when the wind is predicted to be over 20 mph. Sustained winds of 47 mph may be OK as head or tail winds, but when that much power comes from the side? The last time I rode in over 20 winds, a gust hit me as I entered an intersection, and I was afraid it would knock me into the car that was passing me.
