Prolonged Nor’easter to bring significant impacts this week

Hello everyone!

While tomorrow will feature frigid conditions and mainly clear skies in the morning with clouds building in as the day goes on. Frigid temps can be expected tomorrow morning with lows ranging from 10 below to 10 above. I’ll have more details tomorrow morning.

While this update will be a little less detailed than I had hoped, I will still try my best to give you good insight into what will happen tomorrow into Wednesday. Here is an impact-by-impact breakdown of what to expect for the first part of the storm.


There will be lots and lots of rain with this one, no question about it. Expect amounts in the 2-4″ range for Coastal Maine and New Hampshire as well as most of MA and CT as well as all of RI. This is a pretty straightforward forecast and confidence is moderate-high.


If you missed the uncertainty, you can find it here in the snow section. Everyone sees some snow to start Tuesday with ocean effect and overrunning but as warm air works in from the ocean, as well as from the SW aloft, the coast should see a switch to rain and the foothills should see a switch to sleet or freezing rain. After the bulk of the precip leaves Tuesday night, things get even more uncertain because the exact track of the upper low will determine who gets a bonus round Wednesday into Thursday. The map below shows totals through Wednesday Morning with the first round.

South of the red line, expect any snow that falls plus any that is on the ground to be long gone by Wednesday  morning.


Wind will be a big concern here as well due to the developing low and the sprawling high to the north creating a large pressure gradient. Expect sustained winds in the 20-40mph range with gusts over 50 mph possible. There is the possibility of gusts much higher than that but for now 50mph is a safe bet for coastal areas. High winds plus a saturated ground at the coast and heavy snow inland could lead to possibly widespread power outages.

Coastal Flooding

Any time you get a prolonged period of onshore winds, you have to worry about coastal flooding and concerns for coastal flooding are very real along any E/SE facing areas. With a solid day and possibly more of strong onshore winds, expect some splashover and beach erosion.

I’ll have more details on everything tomorrow as the puzzle continues to come together.
