Has there been any other occasion with a 10% hatched for tornadoes in New England?

We've had 10% hatched before but this is the first time with the CIG additions which only became operational some months ago

Lets level Maine and Stein here per 12z hrrr.

Given the nowcast nature of these and the boundary set forth by the initial storms...definitely might want to watch the areas west of where SPC highlights. Just has that look/feel.

12z NAM supports that idea

One time?

Why do you feel the need to hurt me like this?

Did it produce?

Tornadoes no but I think that was the day of the big microburst or macroburst near Boston...either this day or the next. 

[weatherwiz]

One of those two weekend days had a big microbust in CT and the other was up near Boston

Two long tracked supercells that produced swaths of wind damage. Sadly for some, no tornadoes.

I was sitting in the McDonalds parking lot across from BDL when the tornado warning went out and was hoping something would drop

That kind of behavior gets you on neighborhood watch lists.

Not 100% sure but I think that happened within a mile of where I live now

That was a pike SUP that nailed BOS and Revere. I don't think there was much anywhere else.

KInd of a bust with MDT risk IIRC.

Also, we had putrid lapse rates that day. A ton of shear, but not a lot of instability. You know what that means in SNE.

[OceanStWx]

This kind of event has so much potential in New England for main reason that you rotate the entire flow pattern and create something more akin to what happens in the Midwest.

Around here you typically have much more stable air to the southeast, the complete opposite of central CONUS severe weather. Northwest flow allows stable air to be in the right top quadrant relative to the storms. Check out the line of cumulus marking the surface based instability. Also the forecast for theta-e later today. That marks the warm front, and storm motion is parallel to this. So this is the exact orientation you need for long tracked supercellular storms.

The same can be said anywhere really when it comes to lapse rates. There was a setup in the midwest a few months back which was flagged with higher tornado probabilities and potential for strong and long-tracked tornadoes but that never materialized...and it was a setup in which they had relatively weak lapse rates. It truly is hard to get a full fledged higher end severe weather outbreak without the present of steep lapse rates. 

The lapse rates here that day were horrible...but I recall they weren't modeled to be as bad as what actually transpired.

About as useless as today’s event then. An EF3 will probably rip up a few million trees and no one will know. 

[Winter Wizard]

 

The 10% hatching is not unprecedented in New England but has not occurred in that region before.

[Cyclone-68]

If an EF3 hits a forest and nobody is around, does it make a sound?

Yes it does...

That’s why it’s helpful to ask questions lol

Back in college I said the exact same thing to a prof...he said in my case it wasn't helpful for me to ask questions..

As of 11:45 here in Central NH we have a very thick smoke layer above us.  The whole landscape is yellowish and the sun disc is sharp but so dim you can look at it directly.  A very eerie situation.  It is only 74.7F.  I have no idea how this will impact the severe threat later but it is the densest smoke layer above us that I have ever seen.  Meanwhile at near ground level I can see mountain ridges 30 miles distant.
