The Great Lakes Icing

It also looks like the Great Lakes are headed to a very rapid ice-over. This graph is from the 21st of January, before the present cold plunge. Given that we’re headed toward record cold levels in Chicago (on the coast of the Great Lakes) I would expect the Lakes to accelerate their icing.
Has a copy of the image, so prompted me to do a “Go Fish!” here: for my own copy:

Great Lakes Ice - 21 January 2019

Great Lakes Ice – 21 January 2019

Original from:
downloaded 29 January 2019, so things will be more iced over by now, and with near record cold present in the area, ought to accelerate from the rapid rate the article described as having already happened. From that article:

Great Lakes Ice Coverage Doubles in One Week
By Chris Dolce5 days

At a Glance

Much colder temperatures have moved into the Midwest for the second half of January.As a result, ice coverage in the Great Lakes grew rapidly in the past week.Ice coverage usually peaks in late winter.

Ice coverage across the Great Lakes has more than doubled in the past week due to a weather pattern change that has sent much colder temperatures into the central and eastern states.

On Jan. 15 the amount of ice coverage for all the Great Lakes was near 10 percent, which is below the average of 16 percent for that date. But by Jan. 22 ,weekly ice coverage across all five Great Lakes was at 23 percent, according to the Canadian Ice Service of Environment Canada. That’s slightly above the 30-year average (1981-2010) of about 19 percent for that week.

So above average ice, but still we’re supposed to believe it is because things are warmer? “I don’t think so, Tim…” (h/t Home Improvement show)

Now that was before the current cold plunge, so ice growth ought to be going gangbusters now. We’ll need to check back in on it in a few more days / weeks.

I wonder if the Globull Warming Advocates have found a new “warm snow” and “warm ice”… /sarc;


I’m adding an image from the link that Ossqss pointed to in comments (h/t Ossqss!). It’s quite a graph!

    Have a peek at Lake Erie. Quite the jump the last week. Lots of historic info on this site too.

    I added a graph of Lake Eire from your link. OMG what a rocket ride. From near nothing to over 70% in about 2 weeks… Now THAT’s cold!

    Intense cold and wind will do that. Gets wave action up so lots of water droplets get lofted into that very cold are and no thin cap ice forms, then eventually all that water gets supercooled and bam ice forms fast as the slushy surface suddenly gels in to solid ice.

    That frazil ice and mixing from the wind deeply cools the water and sets up for rapid freeze over.

    Lake Michigan wind is westerly, and very cold already -3 to -6 range on the west bank of the lake, and strong wind, ranging from 7-30 mph looking at the entire lake.

    See ventusky at;-87.60;6&l=temperature-2m
    for the 6pm view tonight, and to step the timeline forward.

    THEN, it settles into a night pattern as the freeze deepens, with the really cold air mass arriving at 3 am or so,with a -20 (or so) to -5 gradient west-to-east across the lake fetch, and the associated lake effect snow. This is a set-up for heat swap between the lake and the airmass, and the snow fall from the lake extends halfway (or more) into Michigan.

    My younger son who lives there says that the city is going to shut down for a couple days.

    So we have these real world observations and still, even with Trump in power we have this NASA site spreading utter climate crap 24/7. Its a bloody shame.

    @Steven Fraser: Best wishes for your son. I hope he can hunker down and miss out on any problems. It’s no wonder at all why I see a lot of Michigan plates here at the RV park.

    My wife’s cousin and his wife are in New Holland, Michigan, just shy of a dozen blocks in from the lake. New Holland is about 1/2-way up on the western shore. They are old hands at this and they are still being extra careful with this weather system. (Wife has been texting them about Florida and asking if they are all set there. They are not amused.)

    Our son just stopped by our house about 8:00 pm EST to verify the furnace was operational. We’re good unless there’s a power outage. Nothing to be done about that. If there’s an outage, he’ll pop over, shut off the main water valve and open the faucets Worst case is I’ll have a few drain traps to change out when I get home and we’ll lose all the house plants. That’s if there’s a prolonged outage.

    @H.R. Thanks for your good wishes. Back at ya for your family in Holland. I’ve been there in Summer… quite nice. I’ve also been in St Joseph in the depths of chilly winter snows. Brrr.

    @EM: The Great Lakes ice chart was updated on the 29th. The blue bar now goes above the 40 line, and exceeds the peak average max for the year. Wow! Ice is growing fast. From another chart, this freeze year is now #8 (already) for the week, and could exceed #7 depending on how things progress.
