Wow... what a range!
Im particularly surprised by that 98 because that is even close to the record warmest here. The absolute highest temp for the Czech Republic is 104, but that wasn't where I live, here it is more like 101/102. And I myself have measured over 100 about twice.
That minimum of course is something I cant even imagine, but Im not surprised given where you live
I actually like cold as well, I hate hot weather. But here it hardly ever gets below -5F, which you probably think is absurd
I think the coldest I have ever experienced was -15F, but that is very long time ago, usually in the winter we have daily max around freezing point or 40F, at night it drops to 15-20 F.
