I'd imagine the weather would depend on two major variables: orbital
eccentricity and the wobble in the tidal locking.

The orbital eccentricity would lead to variable temps on the star facing
side, so you'd get a morning sea breeze like effect each year.  I don't
know if tidal locking is compatible with anything other than a nearly
circular orbit.

On the wobble: Evidently much more likely if there is a moon for the
planet, https://en.wikipedia.org/wiki/Tidal_locking#Eccentric_orbits.
This could lead to very interesting patterns, with substantial
variability in the intensity of the seasons.

It's been a long time since I read it, but

be useful.
