Wicked March Part III- Winter Storm/Blizzard Warnings Tuesday

I don’t know how many acts to this play there are going to be (seriously, but we won’t talk about next week until…next week).  Part I featured heavy rain, high winds, and major coastal flooding.  Part II was a power outage nightmare as heavy wet snow brought down trees and power lines all over Southern New England.  Part III is a pure snowstorm that wouldn’t feel out of place in the middle of January.  Blizzard and Winter Storm Warnings are posted across the entire region.  Without further ado…


NWS Early Evening Headlines

The high wind warning/winter storm warning has been replaced by a blizzard warning in Barnstable, Dukes, Plymouth, and Eastern Essex County.  The track is a just a bit too far offshore to bring blizzard conditions to Worcester, Middlesex, Norfolk, and Bristol Counties as well as Rhode Island.  That said, winds will still gust to 30-40 MPH in these regions causing whiteout conditions at times.  It’s just unlikely to meet the official definition of a blizzard.


I’ve pushed back the start of the snow in Central Massachusetts until 3-4 AM.  This goes for everywhere south of the Pike including Boston.  Snow will begin north of the Pike just after 4 AM.

By 8 AM, a healthy 3-6″ will be on the ground in Northern RI and Southern Worcester County.  Snow will be falling at nearly an inch per hour.  By 11 AM, snow will be falling at rates of nearly 3″/hr in SE MA!  The Cape will likely be over a foot of snow by this time.  We won’t be doing badly in the Blackstone Valley and if this backs a little bit further west, watch out.  Snow will still be falling at a rate of 1-2″/hr in Northbridge, Uxbridge, Mendon, Upton, Grafton, Shrewsbury, and most of the 495 belt.

As temperatures fall tomorrow AM in Worcester County, the snow will add a bit of a fluff factor so it wouldn’t surprise me if some of the aforementioned communities along 495 are approaching a foot by late morning.

Snow will continue falling heavily through mid-afternoon, finally winding down in Central MA and RI around 5 PM.  Snow showers will linger in Eastern MA through 8 PM with snow perhaps lingering all night north of the Pike!

This storm is an absolute crush job.  I had some doubts but it has all the makings of a classic.  Boston has a chance at the largest March snowstorm on record.  After thinking the Worcester area would be around 8-12″, I now believe 12-18″ is likely with a few towns along 495 having a shot at close to 20″.  Here is the what the NWS thinks and I can’t say I disagree.

Bring it on!  Of course, this is my forecast for the weekend.  Is this mean?

That was mean, sorry.  Talk to you in the morning about the very latest.
