Thursday, April 16th 2020, 6:50 pm - Even though it is the middle of April, we are tracking a massive band of snow that will bring impacts to millions of people in the U.S. and Canada.
A massive swath of snow will track through the United States and into Canada at the end of this week.
This latest round of snow is due to the jet stream dipping south towards the Gulf of Mexico, which is allowing an upper low to fill in over much of North America and is responsible for the widespread below seasonal temperatures. Cold air will encounter moisture from the southern U.S. and will set the scene for unsettled weather and flurries to continue.
Temperatures are usually in the mid to upper teens from Denver, Colorado to Boston, Massachusetts during this time of year, but most of these regions will be closer to the freezing mark on Friday and Saturday, which is when a 3,000 km band of snow will track through.
Most regions will see a few centimetres of snow, but some areas in Illinois and Missouri could see up to 10 cm. Parts of southwestern Ontario, including Chatham and Windsor, will see 1-2 cm of snow on Friday morning before the precipitation tapers off. Atlantic Canada and New England will then see accumulations below 5 cm on Saturday.
