 The jet steam has a linear trough to the west over the Pacific ocean. The jet stream is moving across the lower half of the US, most likely pulling the trough to the east.

There are multiple different wind patterns over the Pacific and east of the Rocky Mountains. The dominant wind direction is West. But there is still variation where the "lines" are being created.

High amounts of precipitation are forming in the same location in the Pacific. With the wind direction moving from the West and the jet stream staying in the lower half of the US, there will not be much happening in Eau Claire this weekend. Most likely clear or partly cloudy skies. That means that the south is going to get high amounts of precipitation this weekend.

By Saturday afternoon, Texas, Louisiana, and Arkansas are going to see large amounts of rain that could most likely lead to flooding.
