It’s coming in like a wall here. Like a snow squall. Mt Holly just upgraded me to a WSW.

First snow shower of the season in progress here.

3.52” storm total.

I have been under the FFW for over an hour now. Reports of many local roads under water and impassable.

That happened to me an hour ago. These warnings are covering a large area.

Tornado warnings issued for much of central NJ

I am at 3.04 for the day with 2.94 of it this evening.

2.92” of rain so far this evening.

Tornado warnings now in effect for much of eastern/southeast PA right now.

The front looks to be stalled along the I-78 / I-287 / 202 corridor from about Quakertown to Clinton to Far Hills and to the north and east. There is a 10 degree temp difference across the front right now. I am at 56 now and much of NJ is in the 60’s. That would seem to be the area most at risk for a spin up over the next hour or two.

Tornado warnings in effect for a large area of eastern PA right now. 2.66” so far this evening. The triggering mechanism seems to be related to the front which is located just south of me. All kinds of rotation on radar right now.

1.51” on the day so far.

I actually drove up north from LI that morning to see where the accumulations were. I believe it was a Saturday morning. There was a coating on grassy surfaces from about central Westchester on north however it was just cloudy. I drove up I-684 to I-84 going west to see how accumulations were in the high country to the west of Brewster. Once I started going up that grade accumulations started to increase rapidly. I don’t think I got as far as Stormville before being forced to turn around due to heavy snow. At that point there was at least 6” on the ground. It was a classic early season elevation event.

Continuous lightning and thunder with the squall line that is passing my location. Had a period of marble sized hail as well within the past 20 minutes.

I am on board with forky.

Cat 4 130 mph with 5pm advisory.

Strongly agree.

Long Island is part of the mid-Atlantic. Count how many tidal cycles take place while it lingers off shore - that is what leads to tidal flooding. Misinformation- I don’t think so.

06z GFS while a fantasy run would cause massive tidal flooding throughout the mid-Atlantic.

A lot of CTC lightning with it. I had a wind gust of 32 mph when it passed earlier.

There are big time orographic influences that have factored in to those totals. That part of central PA is rugged and mountainous.

Sea breeze front can make for some real interesting weather out there. Way back in 1978 when I lived in East Northport a sea breeze front thunderstorm turned violent and produced marble sized hail and numerous CTG lightning strikes along with strong winds. It was one of the very few times I saw hail when I lived out that way.

There is a history of these convergence zones setting up west to east across LI. There was one a couple of years ago that dumped up to several inches of rain across NW Suffolk Cty.

24 Hour rainfall here was 3.15” from 10:00am yesterday.

I received a total of 0.83 from that line last night. Radar this hour looks similar to about 10:30pm last night with that healthy looking feature near Reading, PA
