If you are so dry that plants are in drought dormancy, then there will be no biological activity. Same as if plants are in heat dormancy. And if very cold, will also be in cold ecodormancy. So any conditions that put plants into eco-dormancy, of any type will prevent rebloom., as well as any other biological activity.
I have had Immortality rebloom in near drought conditions after bud set temperatures.

I disagree, Chuck.  Once they reach maturity, they will <not> start
sending up bloom stalks unless/until there is adequate available soil
moisture.

& soil moisture is a function of temperature, rainfall, texture,
competition (either from other parts of the clump or weeds), wind,
humidity, and preceeding soil moisture.

Plus available soil moisture includes rooting volume/access to moisture.

A little spritz of rain may keep the grass green, but isn't enough to
trigger rebloom in most rebloomers here.

I'm still waiting for the main crop of 'early' fall rebloomers (Violet
Miracle, Perfume Counter, Matrix, Harvest of Memories etc) to start
sending up stalks - plenty of mature fans, coolest temperatures on
record off and on this summer, but very dry until the last week or so.
I suspect if the predicted cooler temps next week show up (lowering evap 
& transpiration rate), combined with rain last week, they will be ready
to start stalking soon.

Soil moisture along will all other growing conditions  is summed up in
maturity.  Otherwise irrelevant. After maturity  apical meristem is
responding to temperatures. A simple min/max temperature record 
will
do. Or a nearby weather station that reflects your climate will 
also

work.

Without soil moisture data, I'm convinced temp and maturity isn't
enough, especially with highly variable soil texture (gravel to clay
with everything in between) and without digging and re-setting every
year, or at least every other year, not to mention variations in weed
competition.
That kind of control and monitoring is for a younger healthier person 
or

a more comfortable summer climate.  ;-)

I don't know how people in southern Alabama, MS, GA, LA survived the
summer before AC.
