Good morning with your US . Ice on the roads this morning on I-80 in Wyoming at Sherman Hill, I-84 in Oregon at Deadmans Pass, and then snow and ice cover for a lot of I-90 and I-94 in the Dakotas and Montana.

Most of that was pretty light stuff (heavier in Wyoming) but all is moving out today and the sun will be out.

But the real story is developing further east with Lake Effect Snows taking hold. Conneaut OH saw snowfall rates of up to 3" (7.5cm) per HOUR last night in the heaviest band for a couple hours. I-90 is defacto closed there due to accidents. Similar snow in west central Michigan, though about half the snow totals

That initial blast cools off, but sets up with a different windward direction tonight. Buffalo New York will be expecting an area of greater than 4 FEET (1.2m) of snow through this weekend in one area, and a widespread area of up to 2 ft. (0.6m). Similar snowfall for Watertown NY area.

Full truck restrictions are in place for I-90 starting at 4pm tonight and continuing indefinitely. Last time they got this much snow, I-90 was closed about 4 days. NYDOT appears much more prepared this time, but we'll see what actually happens. You just can't physically move that much snow - especially once a few cars get stuck.

Good snowy morning to much of the U.S. Snow is widespread for many of the Great Lakes States, but really only seeing it affect the roads in a few select cities this morning - Minneapolis, Milwaukee, Chicago and Denver.

For the most part roads are in good shape this morning, and we'll see a couple more inches of snow in the heaviest bands.

Switches to some Lake Effect snow tomorrow for South Bend IN and Erie PA, and then a mix of some freezing rain for the higher peaks of the central Appalachians tomorrow, and snow from Pennsylvania on up through New York and New England. Similar impact expected as today.

High resolution (2 meters) Pleiades DEM allowed quantitative analysis of the flights of marine terraces marking Kythira island coast.

Thanks to CNES Isis program which provided us with the Pleiades imagery.

Physics Weather

The big blob of cold air, pushed by Pacific plumes has come to the end of its run, stopping just short of freezing the big rocket. The Pacific plumes continue to push straight North, so we can expect more of these 'air glaciers'.

Good morning east of the Rockies in Colorado and New Mexico. Snow is on the road on I-25 in southern CO this AM, and moving east and south through Western KS, the Oklahoma Panhandle and the Texas Panhandle.

3-6" of snow expected on I-40 in W. Oklahoma, as this cold front meets more saturated air and spins up a more intense low (a 'Panhandle hooker'). More modest snowfall expected elsewhere.

WSSI showing a moderate impact expected and outlines I-35 south of OKC as well. Going to see the system split somewhat with NW Arkansas hit with one lobe and Kansas City and norther MIssouri taking the other.

Expect additional advisories potentially expanding at the 3pm updates - and new issued for Pennsylvania/upstate New York for tomorrow.

I spent a lot of time this summer photographing and studying the incredible Osprey. Some of my favorite moments were sitting on the bank of the Tennessee River at either Nickajack or Chickamauga Dams and watching as these incredible hunters fed their families.
This collection highlights a few of the more interesting things about these beautiful birds.

1. Ospreys spend an incredible amount of time flying, their hunting process usually involves circling over a body of water until they spot a fish, at which point they switch into a back stroke and hover momentarily plotting the fishes course and where their strike should be, they then transfer into a dive that usually results in a bad day for the fish.
2. I'm amazed at just how much weight these birds can carry, though I did observe a few times a smaller bird having to give up and drop a catch, only to have a larger, stronger bird swoop in and collect the kill.
3. Just before they hit the water, these birds have a third eyelid, called a nictating membrane that closes to protect their eyes, they often fully submerge in order to collect their prey.
4. Because they hit the water so hard, and often go under the surface, one of their first orders of business is getting rid of the excess weight of the water after a catch. This process involves flying up to about between 2 and 5 meters and then pausing flying to shake, they often take this zero gravity moment to reposition their talons on the fish and orient to the flight direction if they didn't get the perfect grip during their strike.

This week the Cornell Lab of Ornithology released fine scale population trends maps for over 500 North American #birds based on #eBird data. These maps are the culmination of several years of research and development by the #eBird Status and Trends team, and all this work was only possible because of the amazing community of eBirders who contributed 43.8 million checklists to the dataset we used to estimate population trends.

Six weeks ago I first mentioned the potential of a “Falaise Gap” type encirclement in Kherson on @CNN with the potential of the capture of 10-25,000 Russian soldiers. Ukraine reports indicate a rout close to the scale of that is happening.

If RU did not prepare for this & thousands of soldiers are killed/captured, it cements the known incompetence of the RU Army. If soldiers are captured, Ukraine MUST treat them under Geneva convention rules.

Tonight's national weather radar is full of activity. What's left of is spinning in the southeast; rain along the cold front from Wisconsin to Oklahoma; heavy snow in North Dakota and Minnesota. And the appearance of nighttime bugs, bats, and other flyers across the southeast, too!
