We all know the story of glaciers from “back in the day.”  Most of which have been gone for thousands, if not hundreds of thousands, of years.  There are still some in a few modern locales, generally on mountains.  Mount Moran, in the Tetons, is one example that comes to mind.  There are other Rocky Mountain glaciers and Alaskan glaciers – but rarely do we see rapidly moving & newly formed glaciers around the world.  Lake Mille Lacs, Minnesota, changed that over the weekend!

The big thing, at least in my own humble opinion, is that we don’t want modern glaciers!  At least, not at the surface. We’ve got to get rid of them.  And the best way to do that will be by warming up, and luckily we have a pretty robust warming trend moving in for today through Wednesday for much of the nation’s midsection.

It’s great when you don’t even need words or numbers to describe a graphic – and that is exactly what is happening in the graphic above.  Notice those blues in the Northeast.  Those indicate some lingering cold air over the East – but it will be eradicated as we head through the next couple of next.

Now that we’re warming… that means there will be severe weather, right?  Well – for now we aren’t seeing “major” risks over the traditional zones.  We are seeing a small chance for hail and high wind in the far northern Rockies, thanks to a region of low pressure moving in up in those parts.

The areas we’re looking at are the northern and central Plains, and as we head back into the end of the week and the weekend time-frame.

See that area highlighted above?  That is a possible threat area that the GFS computer model is indicating.  The ECMWF (another main long-term model) is showing quite a bit less organization on Friday – so we’ll see.

One thing that makes it more interesting, even if storms don’t end up happening – is 60 degree or higher dewpoint temperatures.  “Real” humidity!  While we will hate it in a month or two, right now we are still wanting it to feel like summer.

Saturday is showing signs of severe weather organization as well.  Some of the same ingredients are coming together for Saturday as well.

So – a lot of “interesting” stuff going on.  We’ll see what happens!

Stay tuned!
