With winds like that, I suppose either shorter or narrow leafed plants would do the best. I'm thinking of ornamental grasses, daylilies, lower sedums, lamiums and alpine type of plants.
For a long term solution how about a wind break, if you don't have something already that is. A taller fence would give some immediate help as a wind break. And planting some tall evergreens to block the prevailing winds will help eventually a few years down the road.
Wind is a pretty tough thing to conquer and I wish you luck!

Agreeing with what was already said, grassy and mounding plants are probably good. Annual sweet alyssum, low growing dianthus and creeping phlox come to mind, as well Shasta Daisies and Gaillardia are pretty tough and haven't blown down at my house. Daylilies and irises wouldn't likely be bothered by wind especially when they aren't blooming.

To add to the list, marigolds are sturdy plants, wave petunias, portulaca, lantana,and begonias. Have you tried planting smaller shrubs such as little leaf lilac, spireas, and global caraganas? Maybe rugosa roses would be able to tolerate the wind as well.

Ricky, I know you have a hard time getting plants because you are remote. So I was thinking of things you can get seeds for. I have extra seeds for Shasta Daisies and Dianthus if you don't already have these and you want some. Let me know.

Oh yeah and I know there are lots of different kinds of begonias but I find the tuberous ones to be very brittle plants. I had one knocked clean off just the other week by a strong wind and found it 3 feet away on the sidewalk :0(

Petunias have been the toughest for me as far as annuals go. We get wicked west winds (can be very cold or very drying) in the spring and fall and my petunias have always held up well.

My Ashleaf Spirea is out by itself in the elements and does well in the wind.

I plan on building my garden fence (plan being the operative word here! LOL!) with upright planks to create a wind break.

I killed my bean seedlings I had started inside this spring in a couple hours in the wind. Ya live and ya learn I guess...

Just a note about irises...mine are all surviving and finally starting to bloom, but they were very slow starting this spring in the cold winds. They just sat there for weeks only a couple inches above ground. I'm blaming the wind anyhoo!

How about some prairie specials like monardas or rudbeckias? Maybe check out some catalogues from Alberta or Sask. Maltese Cross get tall but they have strong stems.

Thank you for all the advice. I have a lot to learn. Your responses are truely appreciated.

Just a little update, Ricky.
My good ol' geraniums are doing very well in the wind (fully exposed and they hardly quiver) and my cosmos have grown stems that are at least 3/8" thick and are doing fine. They have partial shelter from the wind because they are set against the shed, but are exposed to the south and west.
