Some data coming in today indicates a slightly warmer track, so snowfall amounts have been lowerd a bit. However, there is still room for a slight change in track, so please make sure you check in with TJ later today for an updated snowfall forecast. Here is a general timeline:
The bulk of the accumulating snow will likely start after 8 or 9PM, although a few snow showers are possible before that.
There may be a few heavy periods of snow late tonight, so roads could become quickly snow covered.
The snow will mix to sleet, rain and maybe some freezing rain overnight into the pre-dawn hours of Sunday. So by the time you wake up Sunday morning, a lot of the accumulating snow could be gone.
Most of the area will likely be dealing with rain late Sunday morning into the early afternoon. However, northern Rhode Island (especially north and west of 295) may be hagning on to some sleet or freezing rain.
From the mid afternoon into the evening, rain/freezing rain will likely switch back to sleet and snow, although little additional snow accumulation is expected.
Here are the snowfall totals that we are expecting. Keep in mind, much of this could be washed (or squashed) away by rain that falls on top of it by late Sunday morning.
Winds will pick up overnight into Sunday. Some gusts over 40 mph are possibel along the south coast…Block Island and the Cape could get close to 50 mph.
The good news is, the storngest winds will likely be along the coast where the risk of freezing rain is much lower. That being said, our higher risk areas for ice in northern RI and northern CT could still get gusts of 25-30pm….so some scattered tree damage and power outages are possible.
I have not talked that much about localized street flooding, but that will be a risk. This is especially true along the south coast where over 2 inches of liquid (combining rainfall and melted snow/sleet) are possible.
FLASH FREEZE RISK
Temperatuers will likely crash below freezing Sunday afternoon into Sunday night. Therefore, there is a risk of very icy roads. Use caution if you are traveling to a friend or family’s place to watch the Pats game. -Pete Mangione
