December 2015 somehow had it but that was a product of a wild raging MJO through 3-4-5 if I recall right, December El Ninos do tend to be warm but its rarely due to an SER
-
I think a bigger concern there 8/12 and later on the ensembles is the WNW flow if the ridge sets up that strong over the Plains/Midwest. That is going to send big time smoke into at least New England if any fires are still burning.
-
The area consolidating now over W NJ and E PA near ABE is what most likely could hit NYC but even that might pass north of them...would need to see more activity fill in down towards PHL
-
Isolated cells now E of the main area might hit the NYC area or W parts of Queens/Brooklyn
-
I think relative to what models showed yesterday this is more W-NW overall. I think this initial around stays mostly Newark west now, its the activity post 22Z that may be more of a factor to the east.
-
Those areas more south will likely be hit later because of the surface low that forms. You can see on the 3km NAM and HRRR that when that low forms in S PA later the precip explodes in those areas.
-
This event feels easier to forecast than last Tuesday since energy is more consolidated and its also arriving later and not during the AM.
-
The HRRR has tried its last few runs to make it worse too, its delaying or not having that initial 15-18Z push. I think the later it begins the worse it is. Some models still have that period from 15-17z with showers which would probably mess things up somewhat. The system is dynamic enough I think the evening would still be bad
-
Have to watch outflow from that north cell, development could end up occurring into the city or north Queens over the next hour

2026-2027 Super El Nino
SnowGoose69 replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
I'll believe we have a -PDO this winter when I see it. Last winter was the least -PDO in quite awhile. My hunch is neutral is the best we are getting on that scale. I do think what Steve D/Joe B are harping on has some merit that the non Nino region SSTs being so warm is going to likely interfere in some form with the El Nino behaving as a similar type El Nino may have behaved back in the 70s/80s/90s. That assumes IF those non Nino region SSTs are still that warm in Nov-Feb, but given they have been crazy warm like that for seemingly a decade now I'd assume that remains that way this winter. I have no idea what that result is, it certainly does not guarantee it'll be 09-10 or 87-88 again in BWI/DCA but it may mean the winter is markedly colder/snowier than 15-16 23-24 97-98 82-83 were. I just toss 23-24 in the garbage as it basically was a totally nonsensical strong Nino. -
JFK is the only reporting station other than ISP yet to get TS, would be amazing if somehow they dodge it the entire event but that cell 40 mi west might impact them
-
Maybe NYC/N Queens gets clipped a bit by this, there has been a bit of a right turn to it in the last 30 mins but still seems like its the activity near ABE and south that would hit areas south of those which have been getting trained so far
-
That cell in C-NJ all by itself has to be watched to go tornadic over the next hour
-
I don't see much til after 21-22z for areas south, that cell in E PA between ABE/LNS is the area to watch to see if more development occurs over time
-
HRRR may be losing the plot a bit now. 14Z run seems wacky, I don't see that much convection firing over N-CNTRL NJ the next 4 hours. As a result its sort of distorting the 23-01Z impact.
