WNTV Blog for AM Sunday: Snow and Even More Arcitc Air on the Way

Ice Making Weather
Thanks to my good friend Matt Bydlon for this picture of a Minnesota lake that is turning hard! There's going to be some good ice making conditions across much of the Midwest as an Arctic air mass breaks loose and moves in by the 2nd half of the week...

Ice Safety

There is no such thing as 100 percent safe ice.
"When is ice safe?

There really is no sure answer. You can't judge the strength of ice just by its appearance, age, thickness, temperature, or whether or not the ice is covered with snow. Strength is based on all these factors -- plus the depth of water under the ice, size of the water body, water chemistry and currents, the distribution of the load on the ice, and local climatic conditions."

Tracking a Winter Storm
At this point, you may have heard of some big changes coming in the weather department. A strong storm system dropping in from Canada will track across the northern Rockies and slide out into the Plains by early week.

Snow Potential
Take a look at the snow potential thru AM Thursday. Note the heavier snow potential from the Rockies into the Upper Midwest. This developing storm will likely change as it moves into the Lower 48 early this week, so keep up to date with the latest forecast if you plan traveling.

Snowfall Potential
According to NOAA, the probability of at least 4" of snow or more is fairly high from the Northern Rockies to the High Plains

Significant Cold
Although the amount of snow in specific locations is a bit uncertain at this point, the cold air is not! Another (even colder) blast of Arctic air will settle south of the international border by the 2nd half of the week. Here's the progression of the Arctic air mass through the week.

Sunday Temps
Other than a chunk of colder air still hanging out over the Great Lakes region, temperatures for Sunday don't look too terribly bad (yet) for much of the nation.

Tuesday Temps
By Tuesday, the center of the storm will over the Midwest. At this point, heavier snow looks to be piling up across the Upper Mississippi Valley near the international border. Note the much colder air mass that's building up on the north and western side of the storm

Saturday Temps
By Saturday, temperatures will have plummeted drastically across much of the Midwest. This will likely be some of the coldest air of the season for a majority the the Midwest/Plains region. The other thing to keep in mind is that there will be snow on the ground in some of these areas, so the cold air won't even moderate that much through the weekend. It'll still be quite bone chilling!

Extended Temperature Outlook
According to NOAA's Climate Prediction Center, the extended temperature forecast suggests well below average temperatures for the western two-thirds of the nation through the early/middle part of December.

Comet ISON Lives?
Outer Space is incredible! It's amazing to think of how much unknown there is out there and how small we are as humans. Take a look at this video from NASA that shows Comet ISON making a close encounter with the sun on Thanksgiving. You can see that ISON actually survived!
However, the latest from NASA is that ISON is quickly dying...
