Summer heat and the parcel
July afternoons in Arkansas average 91 °F, by NOAA’s 1991–2020 statewide averages, the 9th hottest of the 51. In the West South Central states, Texas (95 °F), Oklahoma (94 °F) and Louisiana (92 °F) run hotter. A closed delivery van or a sunlit mailbox runs hotter still. Transit at ambient temperature is within specification for lyophilized material; the hours after delivery are what to control, so have the parcel taken in and the vials frozen at −4 °F the same day.
Winter cold and condensation
January nights average 31 °F. Oklahoma (27 °F) is colder. A vial that arrives cold should still reach room temperature before the vacuum is broken, so moisture from the room does not condense on the powder.
The full guidance is on the storage and handling page.
