On Friday we had the winter’s first hard frost in the city.

I say this based on my observation of the plants in Schenley Park.  Prior to December 1 we’d had some lightly frosty mornings and one big snowfall in late October, but no frost so hard that the plants broke under it.  Some non-native species continued to bloom.

On Friday the plants broke.  On Saturday the frost peristed until the sun turned it into swirling steam.

Winter is officially here.
