Snow Storms in a Counter clockwise spiral

Right now it's all Snow storms with no rain because of low temperatures in the North Western States. The center of the spiral of snow storms appears to be in Nevada but could move further east over time. So, the storms hitting places like Mt. Shasta have spiraled through California already, gone south over to Las Vegas and Colorado, spiraled up to Idaho and are coming back into Mt. Shasta. I was told by a friend that this is the Northern hemisphere way storms can spiral, similar to the direction water goes down a toilet in the northern hemisphere which is opposite to the water going down the toilet in the southern hemisphere because of "magnetic polarities" manifested through water when spiraling?

One question I might have would be: In a geomagnetic excursion or reversal does all this sort of thing change directions? The answer likely is yes.

Note:
My 19 year old daughter told me that a reverse spiral is incorrect English. So, to be more specific I changed it to a "Counter Clockwise" spiral.

However, when I went online and watched the radar now this evening, I noticed they stopped spiraling and instead mostly are heading in an eastward direction now.
