Anyone have knowledge on the North Houston USPS Distribution Center and when mail flies out?

Any Houston USPS experts here? I am currently in Portland, OR waiting on an important package. The tracking says my package was scanned into the North Houston USPS Dist. Center last night at 8:30 pm. Is there a chance it would have been flown out to Portland last night after 8:30 or is it more likely that it flew out this morning?
