Snow in the southern states and Texas, but the world is warming!! Lol!
You seem to have confused weather for climate. Here's a way to think about the difference, in probabilistic terms.
Let's say you think of the weather as a role of the dice, where the temperature on a given day is found by rolling a bunch of dice and adding up the result. At first, you start with 16 six-sided dice. So, you can have snow if the temp is 32 degrees or less -- meaning you just have to roll a 2 or a 1 on all of them..... that won't happen much, with one roll per day, it'll happen every few years. Now, what happens if you add another die? Well, it'll still be possible to roll 32 or under. In fact, you could roll as low a 17, in theory. It's entirely possible to set a new record low, even rolling with the extra die. But, the more dice you add, the less likely it becomes, and the more likely that you'll roll a record high, while the average for the year will tend to rise.
Obviously, that's not a perfect analogy, since a better model would have the number of dice in your hand changing based on the time of the year, and since none of it is random. But the concept is the important thing. The concept is that on any given day in any given place, you could have temps that are much colder or hotter than normal, while at the same time the big picture probabilities will tend to move one way or the other. Over time, the probability of getting an unusually low temperature has been falling globally, while the probability of getting an unusually high one has been rising, such that on average temps are up about a degree Celsius relative to where they were a century ago.
