It's hard to imagine
what is happening in the atmosphere to cause their development in such
a tighly defined area, but I see them fairly regularly around here.

I would guess the cloud street to be a stationary source of
convective activity that generates them. Then the air mass moves
along with the wind, and a trail of clouds is created much the same as
chains of volcanic islands are produced by a tectonic plate sliding
over a source of convective magma rising to the surface. Of course,
the cloud street could have been the result of a sheer line.

Get your glider certificate, and you'll have a better understanding of
meteorology.
