ELi5: This morning it is 22°. Yesterday morning, it was -3°. Why does temperature fluctuate more broadly in winter, as opposed to summer?

During summer you have sun, which provides lot of the heat to the hemisphere and hearts more since it is more direct. Once the ground and surrounding bodies of water are warm they act as radiators.
During winter you can get cold and hot masses of air rushing from even quite far away. Now since the ground and waters aren’t warm and the sun isn’t heating the mass of air it cools off.
Sun is really important when it comes to the temperature.
