Is the Spring Equinox going to get delayed on Friday?

No, and there have been snowstorms on the spring equinox before (see 3/20/2015 and 3/21/2018). There won't be one this year.

heard they're pushing it back because the ao is apparently dropping

ahead of the storm in the northeast we had arctic cold, those are days long past by for mid march.

It was called a 100 year storm so unlikely to see again in our lifetime if they are correct. 

The arctic cold was extreme for March even back then. As long as we keep seeing snow in April we sill still get snowy March months.

Generally cooler weather will prevail through the weekend. Following a soaking rain on Monday, a shot of much cooler air could arrive on Tuesday. Lows in New York City could fall to the middle and upper 20s with highs in the upper 30s and lower 40s on Wednesday and Thursday. 

However, with the AO likely to remain generally positive, the cool period likely won't be as prolonged as had been the case during this past winter's cold regimes. 

The major weather story next week will be the super March heatwave that will build in much of the western U.S. March monthly records are likely to be smashed in numerous cities.

The ENSO Region 1+2 anomaly was +0.9°C and the Region 3.4 anomaly was -0.1°C for the week centered around March 4. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.80°C and the ENSO Region 3.4 anomaly has averaged -0.23°C. Neutral ENSO conditions have now developed. Neutral ENSO conditions will continue through at least mid-spring.

The SOI was +26.18 today. 

The preliminary Arctic Oscillation (AO) was +3.365 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied 76% probability that New York City will have a warmer than normal March (1991-2020 normal). March will likely finish with a mean temperature near 44.9° (2.1° above normal). 

Supplemental Information: The projected mean would be 2.4° above the 1981-2010 normal monthly value. 

 

Two years in a row of below normal Dec, Jan and Feb. Followed by above normal March.

Definitely going to be cool coming up but I wouldn't expect anything snow wise.

Sure, we have seen snow after the equinox, but how often is it anything accumulating?  Honestly, at this point, who cares about a dusting or car topper?

Don't get me wrong, I'm okay with average temps, not looking for a torch or anything this early in the season, but time to pack it in with the snow now.  You got your KU dude!
