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.  ;-)

where it's finally starting to cool off as the fall pollen season
arrives...
I don't know how people in southern Alabama, MS, GA, LA survived the
summer before AC.
