Sometimes we get a sugar snow. This happens when rapidly
changing air currents bring in a low pressure cell accompanied by a cold
front after a warm day. The skies cloud over in late afternoon, the temperature
drops, and an east wind carries big wet flakes that arrive in unbelievable
numbers. The snow continues all night . One would think that sap flow would
cease under such conditions. But because of the
preceding moderate temperatures and the substantial drop in barometric pressure,
the flow remains prodigious all through the night and into the next day.
The new, wet snow freshens the woods and brings a delightful coziness in
the sugar house. Every bucket will be full and running over, and the sap
is cold and clear.
