Final Snowfall Forecast: 11/26-27
Wet snow and even some rain will develop across Connecticut Wednesday morning. As precipitation becomes heavy between 9 a.m. and noon, some of the rain between I-95 and I-84 will trend toward wet snow. As warmer air moves in aloft during the afternoon, sleet is likely to punch as far northwest as Meriden to Hartford. The southeast corner of the state may even see plain rain for much of the event.
The heaviest snow will likely fall from late morning through the early evening hours across the hills near and northwest of I-84. Here, a 7 to 11 inch snowfall is forecast. From I-95 up to about I-84, an average of 4 to 7 inches is expected, with the highest amounts being inland and across the hills. The I-95 corridor can expect 2 to 4 inches of a very slushy, wet snow.
Further discussion for the region:
An early season storm is expected to bring a heavy, wet snow to the interior hills of the upper mid-Atlantic region and New England on Wednesday into very early Thanksgiving morning. While the big cities from Philadelphia to New York and Boston can expect some snow, the greatest amounts will be to their north and west.
Low pressure will develop along the Carolina coast this morning and ride up the East Coast. With the low passing close to, if not over Cape Cod, no strong high pressure center in place to the north and the fact that we’re still in November, a warm surge of air should penetrate up to and even a bit northwest of I-95. While temperatures from 850mb down to the surface may hover near freezing, a warm layer up around 800-700mb will likely cause melting aloft, meaning there will be sleet and rain. The result is anticipated to be heavy wet snow well inland, but quite a bit of sleet across areas such as New Haven, Willimantic and the western Boston suburbs, with a change to rain in areas including Providence and Taunton. New York City and Philadelphia look to be in a bit of a different scenario, where rain will try to change to wet snow during the day on Wednesday. The time of day will not be favorable, along with the somewhat inland 700mb low track.
The heaviest snow should fall from late morning through the afternoon across northern New Jersey and the mid-Hudson Valley. The hills of interior Massachusetts and central New England should see widespread snowfall amounts over 10″ with the heaviest falling from the afternoon into the evening hours. 10 to 12″ will be common with a few locally higher amounts possible. Due to the localized nature of 12″+ totals, they have been omitted from this map. Snow will taper off to snow showers early Thanksgiving morning and a few flurries could linger into the day in some locations.
Snowfall forecast totals for the big cities:
Boston: 2 to 4 inches
Worcester: 8 to 12 inches
Providence: 2 to 3 inches
Hartford: 6 to 9 inches
New York City: 1 to 3 inches
Philadelphia: 1 to 3 inches
