Winter/Snow Tires in the Rain

[Helihover]

Just not feelin too great about my X in the rain at highway speeds. The vehicle easily hydroplanes at around 50-55 mph when the rain starts to to accumulate in the "ruts". I'm new to Oregon (born & raised in SoCal), so I'm not the best rain driver. In Cali there are concrete grooved freeways that disapate water more efficently and it never rains there. So here in Oregon there is assfault used for the highway surface along with cars using studded tires creating these ruts. It rains a lot here and along with the ruts on the highway, makes for standing water.
I honestly feel it's my tires. I have to stay in the slow lane while getting passed by all sort of vehicles. Not just preformce oriented vehicles, but minivans and Hondas. If it is my tires, then it makes absolutely no sense to run winter tires in the pacific nw. Anyone have experience driving in heavy rain with winter tires?
