So just how bad is it going to be with just a soft top up here during the winter? I moved up in February and really haven't seen anything that warrants going through the effort of converting to a hard top.
The YJ isn't my daily driver but do want to be able to run her into work once in a while and weekends.
Where I live we get quite a bit of snow. Its the heavy wet snow common to the pacific coast. We call it Sierra Cement. It has not effected my soft top at all, but I do knock it off constantly just to be sure.
What's a "little east" of Seattle mean? Redmond? Issaquah? Or further up where it really snows?
I lived in Seattle and Redmond for 12 years, and had soft tops off and on through those years. I was never really too cold. But a few days I wasn't too happy either.
I always had more problems with crappy windshield wipers and defrosters that worked about as well as having my dog pant on the windshield. But I was in old-school CJs. I had to buy those hair dryer fans. Which don't work either.
You won't have any problem, where you are you might see 4 or 5 days of snow.
I used to sleep with the windows cracked and engine off during the winter when I was based out of Sumner and Tacoma. Winter over there is very mild.
ETA, I went through a winter over here in my YJ with the softtop and had no problem staying warm.

Arguing with a truck driver is like wrestling with a pig in mud, eventually you realize the pig enjoys it.
If it's not your daily driver you should be fine - certainly not worth investing in a hard top for the few weeks where it's cold enough to make a difference - that money could be much better used elsewhere on your Jeep
