I added the snow maps that I used in the Video below. The clipper will bring nuisance snows while a snowstorm will hit the Northern Plains next week.

The clipper that is producing the snow across the Midwest and Great Lakes will also bring snow to the South and Northeast. In general 1-4 inches of snow will fall as in some cases rain changes over to snow. The Northeast will get some extra snow as a wave of low pressure develops along the arctic front.

(note: I am using the NAM 3km snow map because they seem to be close to what I am thinking.)

I do think the I-95 corridor cities should see some snow, maybe up to an inch or so.

Behind the storm, it will get very cold for a few days highs in the single digits to the the teens. The good news, the cold weather will only last for a couple of days before the mild weather comes back.

We do need to watch Buffalo, NY for a lake band to come in on Wednesday as the flow goes around to the Southwest for a time.

The South may see accumulating snow as the cold front changes the rain over to snow for a few hours. Again, it’s probably an inch or two of snow into the deep south, but that also means icy roads too.

The clipper will bring more snow to the Midwest and Great Lakes before the extreme cold gets in. Michigan will be hit hard today with up to 8-10 inches of snow. lake snows will be very heavy with a foot or two in the traditional lake areas.

The arctic airmass that will hit the Northern Plains and Midwest will  be very dangerous in regards to the temperatures alone. Add in the Wind Chills and we are talking temperatures -20 to -60 degrees. If outside you need to dress properly or you will be at risk of Hypothermia . The good news, the cold air comes in and leaves just as quick so it’s a two day shot of cold and then it warms back up.

Snow will come with the clipper that will bring the dangerous cold air. I posted the NAM 3KM snow amounts below to give you an idea of how much snow will fall across the Plains into the Great Lakes. Snow ratios will be high so some areas may see up to 8-10 inches of snow. Chicago for example will have 3-9 inches of snow while Milwaukee will see 5-10 inches of snow.

A lot will be happening this weekend into next week as an extreme cold airmass comes down behind a clipper. The question becomes, will a wave of low pressure develop along the arctic front and bring snow into the East? Some models have  the event and others do not. ECMWF has it but the GFS does not. Keep in mind, the GFS did better last week.

I think all the models are hinting at something happening behind the arctic front in the East but just how much snow is unclear. I do know that a swath of 1-8 inches of high ratio snow will move down from the Northern Plains, through the Midwest and Great Lakes into Ontario and Quebec. Chicago for example should see 4-6 inches of snow with more on the north side of town.  Chicago will also see highs below zero next week.

Lake Effect snows in Michigan should be fairly impressive behind the arctic front.
