Today's #EuropeBigWet Update.
The main source of water into the European zone remains a flow of water across the Sahara north, now on a broad front bringing rain along a 1700km wide front from France to the Aegean.

Notably the unusual circulation of thunderstorms north of the Black Sea has grown to 2000kms wide and now extends all the way to the Baltic. This system appeared with the #WesternSaharaPlume and appears to be fed by it.
This animation from @Meteoblue shows an apparently connected outflow heading East across northern Russia.
@garydchance The UK will be sharing versions of this with everybody. This latest bout of inclement weather is an equal opportunity EU wide event.
Those unfortunate to be living around the Black Sea have already been experiencing the first phase of it for nearly a week. Here's their today.

@garydchance Sardinia and Corsica and then Northern Italy are next in line. The Alps usually puts on an amazing show when impacted by a high pressure #WesternSaharaPlume, would love to see your project's data on the lighting activity this evening @garydchance.
Rains in Ethiopia and adjacent East African parts of the the Nile watersheds have been pumping today. Also across Somalia and Somali land, Sudan, South Sudan and south into areas west of Uganda feeding into Lake Victoria.
Today's rainfall forecasts follow with commentary.

The image above from @NASA Modis shows the upper Nile Basin and areas to the west this morning.
This animation below shows the same area this evening. Storms are once again dancing off the coast of Jeddah, rain surrounds Medina and clouds are gathering over Chad and Sudan.

Here's a close up of the cloud formation over Chad and Sudan today. If you look closely you can see two layers moving in different directions. Some clouds aligning with the westward motion of the monsoon and others, lighter in colour moving north east.
Well its hard to know where to begin with today's #MiddleEast and #HornOfAfrica rainfall forecasts.
The action is now further north, and west. Here we see the consequences of the first phase of what appears to be becoming a continuous #WesternSaharaPlume.

An bit of a battle us underway between a high pressure system over Northern Erope and the plume which is entering at the bottom left in this image of Jetstream level 250Hpa 11km high winds.
While the model forecasts remain optimistic that an orderly jetstream may eventually appear, so far this has not happened. And in the meantime these winds are picking up moisture in the tropics and taking it in large quantities to places where its not expected.
