Original story:

After a week of writing about this possible developing major snowstorm, we’re almost here and it looks to be a significant winter storm, according to the latest information from the National Weather Service.

The National Weather Service says the conditions for Fairfield, New Haven, Middlesex and New London counties could be “near blizzard” like as strong gusty winds will make visibility very low. Traveling Saturday afternoon and evening may be very difficult, the weather service says.

The snowfall projections are all over the place with a minimum of two inches, and a maximum of eight inches possible. But this appears to be a storm where the closer you live to the Shoreline, the more snow you’ll receive, likely in the six-inch range.
