12z GGEM shifted east. Now the low goes east of LI. Still all rain for the majority of the northeast except for far interior areas.

I don't see any way that this could be snow for the coast or really anyone outside of the mountains regardless of how it tracks. The airmass as the storm arrives is putrid to put it mildly. The storm has no access to colder air and the high is retreating east. Pretty much the worst combo possible.

Unlikely in an El Nino...possible, you can get suppression sometimes which occurred for a time in 87-88, 02-03, and 09-10.

January is slightly drier than December during el nino years...December 1969 was near record wet while January was record dry...

60kt winds over much of the area at 925mb. A met can comment on how much of that would transfer. This looks like a damaging storm. Saturated ground, strong winds and intense rain.

 

winds will be strong…this looks similar to march 2010 to me

we are still feeling the effects of this storm at 12z Thursday…..a little over 48 hrs

Not sure if we'll see the same winds/erosion but definitely shades of 12/92. That storm lasted over 48 hours with an inch of snow on the back end. Sustained winds of 40-50 mph away from the coast

Just a ton of moisture available as this originates over the Gulf Stream.

The LLJ looks impressive out of the east while the pressure steadily

falls from 1009 mb 12Z on 995 mb 0z on Tuesday. That is a very 

tight gradient with the 1040 mb high to the north focusing strong winds

and moisture inflow into the area.
