Have you considered a move to here?...

The forecast is just a bit cooler, but it is generally dryer than Iowa. Lots of unoccupied land, and if you build a house, every way you look out the windows would be north. Not sure about the employment or school situation there. Kids would probably enjoy the penguins on trips to the coast.

Sorry to hear about all the sickness and the cold spell. It sounds miserable.
