What weather would result from this illustration?

Nothing spectacular. A front is based on the movement of the cold air.. so what you’d really have is a fast moving cold front. It wouldn’t be like two armies clashing in a medieval battle.

It would simply undercut the warm air. Depending on the steepness of the cold front and the stability and moisture content of the warm air... you could have anything from cloudy skies to a squall line.

Since we have air masses, the variation in temperature and humidity will not be that great in a horizontal direction. The winds will mix the air together within the air mass and the temperature of the surface it’s moving over will further modify it. This even happens at the front itself... causing frontolysis or turning it into an upper front.

No weather would result from this illustration. The reason why no weather would result from this illustration is b/c weather does not result from illustrations.

Tornado?
