atm in the mod...All storms move in a straight line differing only in direction and angle...
How about real storm fronts where u see a line of storm heading your way with a development angle...Like low and high pressure system
Plus..isolated storms move in a random/changing direction`
Plus.. As stated here #120 -weak storm that reenter a low pressure system/move away from a high pressure system while moving over an area with good moister levels should regain strength and vice versa

Thank you :)

When this mod was in alpha, tornadoes could actually change direction via wind direction.
