Winter Not Ending Quietly

April 22, 2013; 9:49 AM ET

Monday, 11:30 a.m.

Someone brought to my attention a telling stat earlier today, out of Rapid City, S.D. Their snowfall so far this month (as of midnight) stood at 37.4 inches. Again, that was as of midnight, and it has been snowing - hard - since then. I would imagine they've picked up a few more inches since midnight, and that would mean their total snow fall in April has now exceeded their average annual snowfall - again, in April! That should give you an idea of just how cold, stormy and snowy this month has been.

And it's not quite over yet.

As I mentioned, it's snowing now in the Black Hills of South Dakota thanks to a rather weak wave of low pressure that is moving out of Nebraska into Iowa. It's snowing in much of South Dakota, for that matter, and even into northernmost sections of Nebraska. With the low developing this afternoon and tonight and heading into Wisconsin tonight, it will spread a burst of snow across northwestern Iowa into southern and eastern Minnesota, northern and western Wisconsin and the western part of Michigan's Upper Peninsula. Several inches will pile up, and a few places in northern and northwest Wisconsin into westernmost Upper Michigan could wind up with more than a foot of heavy, wet snow.

That's wave number one. Right behind it is wave number two, one that is accompanying a cold press down the Front Range. It hasn't taken long for the snow to start flying right behind the front in Cheyenne and Laramie. That process will be repeated in Colorado this afternoon and tonight. Some of that snow will spread out intro Kansas tonight, with a thin strip of snow on the northwest flank of that wave through parts of southeastern Iowa and maybe far northwest Illinois into parts of southern and eastern Wisconsin. Most of the precipitation once this feature exits the Rockies will be in the form of rain, not snow.

Oh, there's still another wave of low pressure behind it, and it, too, will generate some snow. Thankfully, of all three, it will be the weakest of them all, and the precipitation will be the lightest Wednesday over the eastern Dakotas into Minnesota with more snow showers than anything else. That will also spread into parts of Wisconsin and northern Michigan Wednesday night.

While this chart may be a little hard to read, it should give you an idea of how much snow is STILL on the ground in Canada for so late in the season. It is in centimeters:

If you do the math, that's as much as 2 feet of snow still on the ground in parts of Ontario and a foot or more in large portions of Manitoba into Saskatchewan! That's just amazing for so late in the season, and with the cold air that is hanging on for dear life across Canada right now, that snow won't fade away quickly.

There is a light at the end of this long, wintry, cold tunnel, though. It's looking more and more like the last of the really brutally cold air masses coming out of Canada into the Rockies and Plains is this one. The next blast doesn't appear likely to get as far south this weekend into early next week, though it does turn colder over the interior Northwest, the northern Rockies and northern Plains yet again. More importantly, though, it is looking as if the cold will shrink considerably after that in Canada.

Maybe, just maybe, we can all put winter in our rearview mirror after the coming days!
