Reading what is going on with these #AfricanWaterPlumes and their impact on Europe is getting a lot more difficult now. Here's a bunch of informed guesses. Informed by the animation that follows.

While its not immediately obvious the plume on the far right - that has done the work to get everything moving again and break the #BalticFaceoff - is powered by moisture from both the Atlantic and North Africa, merging on the Spanish border with France.

For background #BalticFaceoff >>

These simulation weather maps (CMC model) are of the situation as it is now. The UK now Danish storm is surprisingly dry and it hasn't moved that much the dominant influence on events is actually the combined flow of moisture you can see in the center of the picture.

This animation shows #AfricaPlume activity through to Saturday. As you can see at that point a more traditional Atlantic driven water system becomes dominent but the way they interact wil be interesting.

And here's the ECMWF version (above is CMC), note that the map is a different size - the simulated scenario through to Saturday is very similar to the CMC.

To conclude this bulletin its worth noting that the Atlantic is chock full of moisture at the moment. And the potential storm you see top right in this image is the storm which is heading to the UK in a few days time.
