CLASH OF THE TITANS OVER THE WEEKEND
Friends of RIWMAG and METEOEVENTI here we are again at the weekend preparations.
The week that is coming to an end has brought a lot of cold and also snow on many regions in particular in northern Italy. Let's see if the trend will still be the same or if the weekend will reserve us some surprises.
Saturday, the large area of low pressure that, currently, it extends from northern Europe reaching the North African coasts of Algeria and Tunisia, will continue to influence the weather on the Bel Paese, but it will begin to oppose a promontory of high pressure that, from the Atlantic, will push towards the westernmost regions of the Mediterranean. The minimum ground pressure will move towards the southern Italian regions, favoring a fall ventilation on the lakes and the Bora on the Adriatic.
On Sunday the northern European depression will give way just under the pressure of high pressure retreating towards the Baltic countries.
The baric clash between these two large-scale weather structures will greatly affect the weather on our coasts., giving windy days, thanks to the large pressure gradient that will dig to the ground. Sunday, In addition, we will see a general improvement in the weather throughout the peninsula.

About Great Lakes we will have some residual foehn in the morning.

on Adriatic side the wind from the Northwest will blow from Ancona to the Molise coasts with intensity on the 15/18 nodes. In Molise there will be greater chances of more intense wind up to 20/22 nodes, but with weakly disturbed weather.
