A snow storm that unexpectedly swept across Fairfield and the rest of southwestern Connecticut early Friday slowed the morning commute to a crawl and caused cancellations and delays around town.

Several inches of snow fell by 9 a.m., and with accumulation forecast to continue through midday, the National Weather Service is predicting overall snowfall could be at least 4 inches ... or possibly more depending on the track of the storm.

All classes at Fairfield public and parochial schools were called off for the day.

Also closed for the day was the town’s Bigelow Center for Senior Activities.

Town offices, however, were expected to open, but two hours later than usual.

And the branches of the Fairfield Public Library planned to open at 11 a.m.

The storm, according to the National Weather Service, was forecast to begin tapering off after noontime, with clearing expected by evening.

The outlook for Saturday is brighter, with sunny skies and daytime temperatures rising to about 40 degrees, and Sunday should even be a bit warmer, according to the weather service.
