Your comment is not correct.  These photos were taken on January 14th, 1978 at East Northport on Long Island.  Heavy rain fell most of the night with below freezing temperatures resulting in this severe ice storm.

thankfully uncommon in this area....still remember 94. ouch. my butt still hurts....hint; don't walk out on the ice....

Friendly reminder 6z is usually full of shenanigans, let's keep the overreactions either way in check!

I think you mean 18z an 6z (18z up next) and there’s much debate on how accurate that is. But your point about overreactions is valid lol

18Z GFS late last week had a crazy run with 30-50 inches of snow in PA and some nearby places-it was gone on the next run-but yeah the 18Z run (happy hour run) has shown some crazy solutions over the years

Actually its slightly north 

[NJwx85]

The GFS should be better this run. It’s ejecting the Southern energy faster and the Northern piece is a hair slower and further West.

[Franklin0529]

Yea the icon would've been a foot Plus. Gfs looking much better early on also 

[NJwx85]

The GFS is now very similar to the Euro with how it handles the Southern trough. Let’s see if it holds.

GFS AI way north

Gotta look at the 500 maps! Keep posting (amazing to see a good phase if it happens).

If the temp is 30-31 with the heavy freezing rain absolutely-a lot will just run off. When it gets below about 28 or so much more of it will accrete. 

Agree.  The pictured event took place with temperatures between 28 and 30.  It caused widespread power outages

Seems like its been slowly trending towards doing more of that too. Here's the last 7 runs.

[NJwx85]

Much better

[NJwx85]

Going to be a big hit. Surface is way North.

Yep

[BoulderWX]

IF GFS is right, I'm going to see my family in NC - would be a once in a lifetime snowstorm for them verbatim

Big improvement from 12z but does skirt east before the benchmark; nice run though
