It’s not to hit in a single, wind-driven blast, as has happened in so many Chicago snows. Instead, Chicago’s latest bout of snowy weather is to arrive in waves distributed over a time frame likely to extend into Thursday.
Over time, each of these snowy accumulations is likely to add up, particularly in lakeside counties where the resurgence of frigid arctic air is predicted to activate the “lake-snow-machine”, particularly from Wednesday afternoon forward—a development which may well contribute additional inches of snowfall to the tallies recorded in lakeside counties.
Snowfall estimates reach 1-3″ by midnight New Year’s Eve (Tuesday night); 3 to 5” by Wednesday morning and could top 10” by Thursday afternoon in a few harder hit lakeside counties
New Year’s Eve 2013 is to be a snowy one and care is recommended if you’re planning to head out. But, the bulk of the snow predicted to fall in coming days is to occur beyond New Year’s Eve. And, while snowfall may even pause at times in the days ahead, any breaks in the snow are unlikely to last.
As east winds back northeasterly, the distance they travel over lake water—and, therefore, the amount of moisture which can be expected to be added to this snow system’s tally—is to increase.
It’s estimated the 1 to 3” predicted to have fallen by midnight New Year’s Eve and the 3 to 5” projected to be down by Wednesday morning may build into a few 10”+ tallies, especially in areas with access to lake moisture. Sections of lakeside counties in northeast Illinois, southeast Wisconsin and northwest Indiana stand to see the heaviest snow totals.
This season has recorded 13 times the snow which had fallen a year ago; nearly a foot is on the books
With 11.9” already on the books for the 2013-14 season, snowfall is running at a pace 13 times greater than the paltry 0.9” on the books just a year ago. It’s also at 123% the normal of 9.7” to date.
Monday’s 13-degree high was the season’s coldest yet; only one day ALL last winter was colder
It was cold Monday—VERY cold! In fact, the day’s 13-deg high was the chilliest on the books to date this season. And, interestingly, only one day ALL of last winter produced a colder high temp—the 11-degree high recorded last Jan 22.
But chilly as Monday’s 13-degrees was, it paled in comparison to the 40-below min temp recorded Monday at Embarrass, MN.
Thirty other weather observation sites in Minnesota recorded Monday morning lows of 30-below and colder!
Among the colder Minnesota morning lows Monday were 37-below at International Falls; 23 below at St. Cloud and 21 below at Duluth.
The clock’s ticking on a December 12.5-degrees colder than a year ago
This month’s average temperature of 23.9-degrees to date makes it the coldest December in 3 years. The month will close midnight Tuesday night/Wednesday morning having averaged an eye-catching 12.5-degrees colder than a year ago.
