quando si dice outflow boundary....

[Tornado1977]

I completely disagree with you...
The inland boundary of the sea breeze it's clearly visible during the whole satellite loop and it remains stationary at about 8-10 miles far from the coast. Why should sea breeze gain hundred of miles inland only (only!) near central "Pianura Padana" and not in Northern Veneto or in Romagna?
Even the speed of that "mesoscale front" is not compatible with sea breezes' one... Too fast!
Finally, it is true that sea breezes are relatively strong during this season, but not so much!

Giusta analisi!
