February 17th Update

Quick thump of snow Saturday night

A quick thump of snow Saturday will temporarily change the landscape in Southern New England. The fast-moving storm brings a period of moderate to heavy snow between 6-9 pm Saturday and 5-8 am Sunday, with the height of the storm around midnight. 1″ per hour snow rates are possible as the storm passes by overnight. It will be a wet/heavy snow, and without much wind the snow will stick to trees and weigh them down.

The most likely scenario is for 3-6″ of snow in CT, RI and SE MA. 7-9″ cannot be ruled out, but it will really have to come down for a little longer than expected to pile up that quickly. The snow ratio will likely be between 7:1 and 10:1. That’s a spring-like snow, with a lot of water in each inch. The temperature will be in the low 30s during the event. It’s possible there will be mixing at the coast, and that may keep totals down in the 1-3″ range in those areas.

The EPS Ensemble Mean snow forecast looks pretty good for Saturday night. Highest totals just off the coast in Southeastern New England

A very quick meltdown is likely Sunday into next week. Expect some sun on Sunday with highs in the mid 40s. A refreeze of slush and puddles is possible Sunday night as the temperature dips below freezing. It will be mostly cloudy and mild on Monday, with highs in the mid to upper 40s. Rain showers are likely Monday night as warmer weather arrives in the midweek.

Tuesday, Wednesday, and possibly Thursday will have a spring-like feel. Expect highs in the 50s at the coast and 60s inland Tuesday and Wednesday. It looks like a front will move through on Thursday, sand that should keep the temperature in the 50s. If it slows down a bit, then Thursday could pop into the 60s, too. While it cools down late in the workweek, it certainly does not get unseasonably cold. Expect highs in the 40s on Friday. The early outlook for next weekend is for some rain showers and another warm-up!

GEFS temperature anomalies are quite warm for the end of February!
