November in Lone Tree: afternoons around 48°F, nights around 28°F. A box that waits outside overnight can freeze, so jams, sauces and fresh fruit do better at an office or a front desk than on a porch.
Freezing nights (January, February, March, November and December). The average low reaches 12°F in January. Jams, sauces and fresh fruit should not spend a night outside; offices, senior residences and hospitals all receive indoors.
Snow (January, February, March and December). About 28 inches a year on average. Allow one extra business day when the date matters: a birthday box that ships two days out still lands on time if it leaves three days out.
Wettest months (June and May). Around 5.5 and 5.1 inches of rain on average. Boxes are sealed, not waterproof: a covered porch or a workplace address keeps the packaging presentable.
