WEATHER UPDATE: More Snow Accumulation Now Predicted For New Canaan

Since early this morning the National Weather Service has upped its snowfall accumulation for the area as more cold air is expected to keep more of the precipitation as snow on Monday as opposed to mixed precipitation.

This morning the National Weather Service predicted 1-3 inches of snow and ice accumulation as the precipitation was expected to mainly be a mixed bag.

Well that’s changed and the National Weather Service is now predicting 2-5 inches of snow and up to a quarter of an inch of ice.

So the storm’s gone from a nuisance to potentially a true hazard for anyone driving in it.

Here’s the timing of the precipitation:

A mix of snow, freezing rain and sleet will continue this evening but will transition over to mainly snow by late Monday morning, which will make travel “hazardous” the National Weather Service states.
