"But a lot of what we have been seeing is more like ice pellets or hail, that you would have quite a bit of trouble making a snow ball out of."
Corrigan said today's conditions couldn't be compared to the 2011 "outlier" Wellington weather when snow fell in seaside suburbs such as Oriental Bay and in the CBD.
The bitterly cold conditions were being driven by a flow from Southern Ocean and, while any icy showers should clear this afternoon, the chilly conditions will remain.
"That cold showery flow has brought in some really cool air and that's hanging around for the next few days."
