Quite a bit of snow overnight in Londontario! Will measure later but looks like 20 cm, on top of around 5 cm already on the ground - at least here in Old North. Roads are in pretty bad shape currently. #ONstorm #LdnOnt

The polar shaft is normally a lot larger but it’s quite cold out and shrinkage is having a big influence.
