fuagf -- once initiated by the pyro effect in an environment with the requisite instability, a precip-producing cumiliform can continue, and in the right ambient conditions even intensify, even as and after the prevailing higher/cloud-level winds move the cumuliform away from the point of its initiation with the assist of the pyro effect -- just as, for example, storms that initiate over the front range of the Rockies, with the assist of the orographic effect working on low-level (relatively) moist inflow into the foothills, can persist for many hours, and become severe/tornadic, as the higher/cloud-level winds carry them well east of the mountains (and into much more moist/unstable air) -- often developing into mesoscale convective systems that can track east to the Mississippi and all the way down into Texas -- once the cloud is initiated, under the right conditions it can and will keep on going
