Storm updates are done for tonight. The next update will be posted on Sunday with a summary of today's storm activity as well as an updated forecast for the area.

------------------------------------------------------------------


5:31 PM: A Tornado Warning is in effect for NW Bergen County into SE Rockland County associated with a severe storm. The storm is capable of producing strong wind gusts along with heavy rainfall.


4:20 PM: Line Ahead of Schedule

The severe squall line is already ahead of schedule, and is entering NW NJ. Severe storms are quickly developing just ahead of the line, and the line is expected to persist into northern NJ and SE NY, the area I highlighted for the biggest impact from the squall line. The line collapsed in SE PA and southern New Jersey, and may weaken extending further north as far north as NYC, although the severe storms are still expected to focus over NW/north central NJ and SE NY over the next 2 hours, ending by 7 PM. The biggest risk from the line is strong/damaging wind gusts, with small hail and heavy rainfall additional risks.




3:25 PM: Squall Line Approaching

Since the last update, additional scattered severe storms developed over NE NJ, with a tornado warned storm over NE Bergen and SE Rockland counties. The storms have moved to the north of the area, although  attention now turns to the squall line over central/eastern PA, which is intensifying while moving east towards the area. The line is ahead of schedule, currently located further east than modeled, and is expected to move into northern NJ, SE NY and NYC between 5-7 PM. The biggest risk with this line is strong/damaging wind gusts, along with small hail, heavy rainfall, and the additional possibility of isolated tornadoes.



12:15 PM: More Severe Storms Today

An unexpected morning round of severe thunderstorms developed over the immediate NYC area, which resulted in two tornado warned storms, one in Brooklyn and the other in Rockland and Westchester counties. The most significant storm was over Queens, specifically in Breezy Point, where there are many reports and videos of a tornado touchdown as well as reports of damage and flash flooding. More updates on this will be posted as new information comes in.

Although the morning round was unexpected, more severe thunderstorms are expected today. Isolated storms are expected through the rest of the afternoon, with some of these storms also capable of becoming severe with strong winds, flash flooding and isolated tornadoes. The main event is expected to be tonight with a strong squall line which is currently near western Pennsylvania. This line is expected to contain strong to severe storms as it moves east into New Jersey later tonight, towards 6-8 PM. The strongest storms with this line are expected to stay north/west of NYC, especially from northern NJ into the Hudson Valley. The latest model guidance, however, shows weakening in the line once it reaches NYC, with some models entirely collapsing the line once it passes NYC and SW CT. More information will be posted on the evening outlook later today.

12:22 PM: Tornado Warning remains in effect for Stamford to Danbury, CT. Strong storms are rapidly firing up over NE NJ, no tornado warned storms yet but flash flooding is possible with the storms training just east of the Garden State Parkway.

11:31 AM: Another Tornado Warning is in effect for parts of Rockland and NW Westchester counties in NY. The storm is located near northern Rockland county, moving to the NE.

There are reports of a tornado touchdown from the earlier tornado warned storm near Breezy Point in NYC. Multiple images posted online show a tornado, along with reports of damage in that area.


10:46 AM: A Tornado Warning is in effect for Brooklyn, NY. The severe cell is moving NNE into Queens, later on into far SW CT.

More updates will be posted soon.
