The jet stream continues to drive weather fronts towards the UK in the coming days 🌧️🌬️ As the jet stream moves north, mild air will push in from the south, perhaps bringing highs of 17°C in some spots by Tuesday 🌡️ | Met Office

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

Here's a look at how the jet stream will play a pivotal role in the weather we can expect this week | Met Office
