Well, over here, we get just enough wind to drive the cold clear into your bones( 4 to 8 mph). VERY seldom enough to cause our snows to drift and 14" to 20 " is a really monumental amount of snow for any single event. 4" to 8" is closer to normal here.
There are some definite + & - points to a blower. They are expensive and if you have a big tractor, well, then the blower costs can be astronomic. Believe me driving in reverse with 3-point blower can end up being a "numbing" experience, no matter what size tractor you operate. A good blower can handle the deepest snows - whereas a rear blade may struggle with most anything over 12" to 16". The rear blade will get the job done - it may take multiple passes to clear down to bare ground if you are dealing with really deep snows. With a blower you can "put" the snow exactly where you want it - this may be more difficult with a rear blade. I can clear my mile long driveway and mailbox area in an hour with the rear blade. With the blower it always took 3 + hours to clear the same. No matter which way the discharge chute was pointed - the snow always seemed to drift back on me and I've alway had open station tractors.
