Disrespectful Wisconsin Weather

One of our recent hires for the 2016-2017 school year recently observed (rather publicly) that Wisconsin weather was being disrespectful:

Well Alana, we here at Residence Life agree with you! Almost all of the snow was gone yesterday... but today it was all back. Fortunately, our friends at the Met Office (formerly known as the Meteorological Office in the United Kingdom) has some explanations for us as to why snow forms! Check it out below:

How is snow formed?

Snow is formed when temperatures are low and there is moisture - in the form of tiny ice crystals - in the atmosphere.
When these tiny ice crystals collide they stick together in clouds to become snowflakes. If enough ice crystals stick together, they'll become heavy enough to fall to the ground.
How cold does it have to be to snow?
Precipitation falls as snow when the air temperature is below 2 °C. It is a myth that it needs to be below zero to snow. In fact, in this country, the heaviest snow falls tend to occur when the air temperature is between zero and 2 °C. The falling snow does begin to melt as soon as the temperature rises above freezing, but as the melting process begins, the air around the snowflake is cooled.
If the temperature is warmer than 2 °C then the snowflake will melt and fall as sleet rather than snow, and if it's warmer still, it will be rain.
'Wet' snow vs. 'dry' snow
The size and make up of a snowflake depends on how many ice crystals group together and this will be determined by air temperatures. Snowflakes that fall through dry, cool air will be small, powdery snowflakes that don't stick together. This 'dry' snow is ideal for snow sports but is more likely to drift in windy weather.
When the temperature is slightly warmer than 0 °C, the snowflakes will melt around the edges and stick together to become big, heavy flakes. This creates 'wet' snow which sticks together easily and is good for making snow men.
