Last night the temperatures plummeted to 12 degrees (F). We had 4 to 5 inches of snow the day before.
Temperatures are forecast to only reach freezing for the high for the next week. This is not the wet snow and gone by noon snow. It is cold.
Those pansies, are in the house. Winter has certainly returned, with a vengeance. Previously, the soil was still frozen down around four inches. Those top four inches may be in doubt, too.
