Happy Meteorological Winter!

Happy Meteorological Winter! 12-1-16 met winter

What’s that, you ask?

December 1st marks the first day of Meteorological Winter, which is a 3 month period that meteorologist use to keep track of weather data and history. “Meteorological” seasons are based on yearly temperature data, whereas “astronomical” seasons (what most people use) are based on where the Earth is in relation to the sun.

So how long are we in this Meteorological Winter?

Here’s the answer: Three. long. months.

Just kidding, I’m actually pretty excited to get into colder temperatures. In fact, I’m hoping for a couple of big snowfalls this winter, especially after a few days in the 70s this November.

So let’s talk a little bit about what Meteorological Winter (December, January, February) is typically like for us here in northern Illinois.

December
Early December afternoon temperatures typically bring us to a high near 40 degrees or just below that. However, the entire month holds an average high temperature of near freezing (33.2 degrees), with an average overnight low temperature of about 18 degrees. We average in a little more than 11 inches of snow.

January
Say hello to the coldest month of the year! High temperatures average around 29.5 degrees and low temperatures around 13.5 degrees. January usually brings us around 10 inches of snowfall.

February
Ah yes, the final meteorological winter month. February turns out pretty similar to December, with an average high temperature near 34 degrees, and a low near 18 degrees. It does differ in snowfall, bringing in an average of 7.7 inches to Rockford.

Enjoy the next three months- Meteorological Spring will be here before you know it!
