Got down to the same... -23.5C(-10.3F) this morning.
We have some patchy freezing fog going on. It clings to the trees and crystalizes, looks pretty awesome when seen from a warm automobile.
Edit: Eager to see what the groundhogs think of this weather.
So far:
Punxsutawney Phil (PA) says 6 more weeks.
Shubencadie Sam (NS) got snowed in and cancelled the event (early spring by default)
Lucy the Lobster (NS) did not see a shadow either (lol @ lobster).
Fred la Marmotte (QC) says early spring. ~36% record.
Wiarton Willie (ON) early spring. He has a poor record ~30%.
Manitoba Merv (MB) says 6 more weeks. He has an excellent record ~72%. He's a puppet and not a groundhog.
Balzac Billy (AB) says 6 weeks. ~42% record. Also just a dude in a groundhog costume.
Van Island Violet (BC) says 6 weeks.
