Here's an animated forecast of the developing weekend storm and the precipitation it is to produce from now into Sunday night. | Tom Skilling

This animated JET STREAM FORECAST shows how the northern and southern streams are to combine or "phase" to generate the vertical motions in the atmosphere which will drop Central U.S. barometric pressures precipitously---generating wind and significant precip in the process. The color scheme highlight wind velocities. Note how a powerful phased "wind max" develops aloft over the Central U.S. in this animated forecast. It's that wind max that is to drive rapid intensification of the winter storm

The next weather system, which is to spin up into a significant winter storm--BUT TRACK NORTH OF CHICAGO as it does---is diving southeastward out of the Gulf of Alaska into the Pacific Northwest. You can see a "curl" in the clouds coming off the Pacific near Vancouver Island in Canada. | Tom Skilling
