The area of low pressure that will become our nor’easter has formed off of the Mid-Atlantic coastline this morning and is moving north-northeast. While it’s not expected to be as strong or as large as Friday’s storm, new data overnight is pointing to a storm that will bring several hours of heavy snow, heavy rain and strong winds to southern New England. New this morning, our computer models are trending slightly east with the storm track… which is a colder, potentially snowier scenario in RI/SE MA. By mid-day, steady rain (and some wet snow) is expected to move into RI and southeastern MA. As the afternoon wears on and the storm moves closer, heavy rain (NW RI= wet snow) is likely. It looks like 4pm-8pm is when heavy rain could mix with and change to heavy snow in many inland areas… perhaps all the way down to the coast. Travel during this time is expected to be difficult.
Heavy rain will lead to street flooding, heavy snow will reduce visibility and make driving difficult. The mix of precipitation continues through the evening before beginning to taper to lighter rain/snow showers overnight.
We still anticipate the highest snowfall totals to be well inland, with little to no accumulation from New Bedford to Cape Cod. It’s the area in between that’s tricky. Slight shifts in the track could have a huge impact on snow accumulations. In fact, snow totals could range from 1″ to 12″ over a distance of only 40miles.
The snow will have a heavy and wet consistency, like cement, and we will see the bulk of the accumulations between 7pm and midnight.
Regardless, travel this evening will be difficult.
Rain, or the liquid equivalent when you melt down the snow, will total 1-2″. That will be enough to induce another round of minor flooding of our rivers and streams, especially be tonight and through Thursday.
Here’s a look at how the Pawtuxet River water levels are expected to rise, with minor flooding forecast for Thursday. Minor flooding of the Pawcatuck, Wood and Taunton Rivers is also forecast.
It’s not just rivers and streams that are running high. We’ve had several big rain-makers in the last 5 weeks, and the ground is saturated. Make sure your sump pumps are in working order if you are prone to basement flooding.
WIND: The wind forecast remains on track, with gusts 35-50mph possible in the late afternoon and evening, with the highest gusts over Cape Cod and the Islands.
These winds would typically only lead to isolated power outages… but when you add in the saturated ground, damaged trees from last week’s storm and the heavy wet snow that will be caking power lines and branches inland… it could lead to more outages and damage.
Bottom line: Prepare for outages and tree damage and difficult driving conditions for the evening commute. Keep these links handy:
