When it snows in Spring Grove, Virginia
Measurable snow is rare here: only 10 of 22 winters from 1991 to 2020 recorded 0.1 inch or more at Hopewell, Va US, 17.2 miles away, so there is no typical first-snow date to plan around.
For a gardener, snow matters less than frost: a light snow on frozen ground changes nothing, while a hard frost on an unprotected bed ends the season. Use the frost dates above for planting and the snow dates for getting hoses drained, mulch down and tender pots indoors.

ZIP 23881 sits in USDA hardiness zone 7b, meaning the average coldest night of the year falls between 5 to 10°F. Zone decides what survives the winter; frost dates decide when to plant each spring. They are different questions, and a plant can pass one and fail the other.
These are thirty-year NOAA averages for 1991–2020, not a forecast. Any individual year can frost two to three weeks either side of these dates, so check the actual forecast before planting out.
