The hatched area is where the risk of EF-2+ tornadoes is greater than 10%.
Clear signs of rotation approaching the Miami-Dade/Broward/Palm Beach metro area.

This massive system is affecting the whole West Coast, from the #AKwx Panhandle to Tijuana.
If you follow the tail back to #HIwx, you can see why they call it a "#PineappleExpress."

At the moment, the #snow that's heavy enough to reach the ground is staying south of I-78. Some banding/training appears to be happening in Central and South Jersey, too.

Most Snow Squall Warnings are ending.
Heaviest #Snow squalls moving through, now. Snow Squall Warnings are in purple. The Five Boroughs, Bergen, Hudson, Union, and Essex appear to be threading the needle, avoiding the worst of it.
The first #Snow Squall Warnings are starting to appear to our west. Join me for a livestream of the squall moving through, as it gets closer to the urban core (~12:30-1:30ish). It sure beats watching your team NOT play in the playoffs!

She's doing a good clip!
The squall line containing the heaviest rain and strongest wind is now moving through Queens into #LIwx!
The end of the rain is now approaching the #NJwx line from PA.
It looks like there may be some bowing in the squall line. That bow, currently working its way through Brooklyn and Queens into Nassau, is an indication of EVEN STRONGER wind!

Squall line containing the heaviest #rain and strongest #wind is now working its way through #NJwx!
The way this line is moving, training looks to be a serious concern. If you get training, your ark will be blown off course.

From one system, straight into the next. Yet, another soaker. Again. 3in of #rain, Tues-Wed.
As we are all PAINFULLY aware, groundwater, rivers, and streams are already high. Throw snowmelt into the mix, and we have a recipe for more flooding.
There're two key differences between this Tues-Wed system and the flooding rains we've had these last weeks.
The first is the aforementioned snowmelt, especially with 13in snowpacks upstream.
The second is wind. 50MPH gusts. With tree roots in loose mud.

8:30 RADAR UPDATE: Bands/lines starting to become. The first is reaching into the inner #NJwx suburbs.

#Tornado Watches and Warnings are in effect. This includes a #PDS Tornado Warning for Downtown #BNAwx.
PDS ("Particularly Dangerous Situation") Watches and Warnings are rare. Especially in December.
This is the system that will hit the East Coast, tomorrow. It is the first of three systems working their way across the continent as part of the so-called "Atmospheric river."

Some of the strongest precip (so far) is now moving through. Some frozen precip is likely to pop on the scope in winter mode. It is unlikely, however, that much of it will reach ground level. NONE of it will stick.

The NOAA NWS National Hurricane Center cone that we're all used to is for the center of the storm. This one, from U.S. Naval Research Laboratory - NRL, is designed for ships and shows a come for #TS-force winds. It also shows wind radii.
As you can see, the whole Northeastern coast is within the TS cone.
#Hurricane #LEE
3:15PM EDT RADAR UPDATE: Showers and thunderstorms are spreading, strengthening, and training. Flooding is the primary concern, followed by isolated large #hail.
