Polar vortex to bring frigid temperatures across US

The remnants of a Pacific typhoon will pound Alaska with enough force to produce 50-foot waves, then shove across two-thirds of the Lower 48 and drive temperatures to wintry levels next week.

“It’s early in the season, but we are poised for a pure Arctic outbreak,” said Tom Niziol, a winter weather specialist for The Weather Channel.

Forecasters said that the storm, as it approaches the Aleutian Islands this weekend, could be more intense than Superstorm Sandy when it swamped the Northeast two years ago. Weather watchers in Alaska — and Twitter — have labeled the storm the "Bering Bomb."

Global warming to blame?

How will we get to the wsu basketball games?

I looked at the extended forecast for Wichita and it looks like it makes it to Wichita around Tuesday.

Mon, high 66
Tue, high 40
Wed, high 38
Thu, high 39
Fri, high 43

We don't need no stinkin polar vortex!

The polar vortex is always in the atmosphere....even in the summer time.

Traveling to SD going to be effected?

Nope, take shorts. Santa Domingo is perfect this time of the year.

kind of like the virus in Walking dead?

It's probably too early to know for sure. It looks like they are forecasting up to 5 inches for the early part of next week, but no additional precip for the remainder of next week. I'm hoping the weather and temps will moderate at least somewhat by the 17th and 18th, but we are talking about South Dakota in November. If you think it's going to be cold here next week, you should look at the forecast for Sioux Falls. Their forecast fot their highs are about the equivalent of the forecast for low temperatures for ICT.

We shall see. The way this system looks to set up......it's a pretty good analogue for early season snow storms...

That is usually the case. As one might expect it is weaker in the summer and stronger in the winter when there is greater temperature variation between the pole and the equator. Volcanic activity in the tropics often result in a stronger polar vortex for up to two years. The interesting thing is that a polar vortex event like we are about to experience is actually the result of the weakening of the vortex. A strong polar vortex keeps the arctic air contained in a fairly constrained area near the pole. However, the weakening of the vortex causes it be "wobbly" or "wavy" which allows the arctic air to come much farther south than usual. Both the south and north poles have polar vortices.
