Winter Storm Watches Issued. Heavy Snow On Its Way!

Good morning/afternoon/day everyone. Just a quick update to give you an idea of what’s ahead. Winter Storm Watches have now gone up as heavy snow will target much of Northern Illinois Thursday night into Friday. Current indications area we could see a wide swath of 5-9 inches of snow. A couple hot model runs have suggested the potential for more, but others have suggested less, so we will be paying ever so close attention to how this upcoming system is evolving.

The way it looks now, a long slow moving band of moderate to heavy snow will take shape over the area beginning Thursday evening with the heaviest snow falling overnight Thursday and into Friday. The fact this will be a longer duration event of moderate to heavy snowfall rates will allow for greater accumulations. Right now the heaviest amounts look to target northeast Illinois as the system pivots to the south. Additionally this system has plenty of moisture to work with as shown below. 1 inch of liquid can fluff up to some pretty beefy snow amounts!

We will share the latest information as it comes in, as well as provide a more detailed look at the setup in later articles. Below is the detailed warning text from the NWS.
