Biggest hail storm in about 10 years for me, some legit nugs in there.  Impressive !

More frozen in the last 20 minutes than the last 20 weeks it seems like.

 

Not sure where you are at but the cell definitely spiked up through Agawam, Forest Park, and E Longmeadow.  Maybe also up into Chicopee.  Has weakened a bit since.  Anyway, congrats.

Nothing compared to the look on my wife's face when she looked out the window.

My wife is livid.

Wow. That’s sick, but they are getting deformed so tons of latent cooling.

My backyard now.  Increasing rapidly.

This is wild.  What an over-performer on May 11th.  Just pounding snow.

I'm ruing the fact that by next November/December 2020 will have used up all of it's snow allotment

Looks like the deform band is moving a bit east of here.  That narrow higher reflectivity band was just ripping snow.

You should be getting into that.

You love to see it. Latent ftw.

Honestly the models handled it pretty well. RAP forecast soundings have MVL pounding snow right now.

Pretty isothermal up to 2500-3000 ft, but cools that layer quickly from 23 to 00z on the forecast soundings. So you drop a bunch of aggregates into the near surface isothermal zone and you cool from melting down to freezing. Great stuff.

Yes, that looks about right judging by what's outside my window

The QPF seemed to over-perform too.  I mean the summits had to get wrecked with a fast 6-10".

 MVL had 0.76" water in the past 6 hours with H85 of around 0C, that'll bring snow to the surface.

Last four hours especially:

5pm.. 0.19"

6pm... 0.17"

7pm... 0.12"

8pm... 0.16"

That's how you dynamically cool off... keep throwing 0.10-0.20" per hour into the bucket. 

This was more exciting for the surprise factor than the other day locally.

Yep. I didn’t look closely, but I see what you are  saying. Epic.
