Radar suggests several mainly dry hours coming in NYC.

KSAV low of 51 is coldest this early in season since 1999.

That 51 at KSAV is the earliest that cold since 1999!

Delays are currently much shorter on avg vs last evening at LaGuardia, when they were nearing 3 hrs…maybe then will turn out to be the worst of it?? LaGuardia Airport (LGA) is currently reporting normal operations with general departure and arrival delays of 15 minutes or less, according to the FAA Airspace System Status. Arrival Delays: Airborne delays are 15 minutes or less. Departure Delays: Gate hold and taxi delays are lasting 15 minutes or less. Weather/Status: Previous weather-related ground delays from earlier in the weekend have cleared, and current FAA status shows normal conditions.

Suffolk is still by far leading the outages in the area with 10K although that’s still not too bad on a % basis (1.6%). Nassau has 5.5K/1.2%. Total in NY state: 23K NJ: 31K with highest # in Ocean Cty at 8K (2.5%) although highest % in NW NJ’s Warren Cty (5.4%) CT: 14K with highest % of 4% in E CT

Suffolk outages have increased from ~3K (0.5%) to ~5K (0.8%) within the last hour.

Due to WEATHER / WIND, there is a Traffic Management Program in effect for traffic arriving La Guardia Airport, New York, NY (LGA). This is causing some arriving flights to be delayed an average of 2 hours and 42 minutes.

Power outages are highest in Suffolk as a %, but even there that’s only at 0.5%.

Thank you! I had a brain malfunction! I edited my original post to point to the error and correction of dates. I apologize for my mistake. The new map for Oct 5-11 has a slightly stronger cold signal than yesterday’s: H5: @mitchnick

I’m not saying the Euro is necessarily going to be right. But I’m passing this along because it’s objectively determined and easily available to the wx community. So fwiw: The new Euro ensemble (12Z) maintains the 90-100% chance that the 0Z and 6Z had for a tropical storm to form from this: The run from just 24 hrs earlier for the same period had only just over 70% for the chance:

I’ve only rarely seen these very comfy conditions here this early in autumn, especially in recent decades: SKY/WX TMP DP RH WIND PRES REMARKS SAVANNAH ARPT MOSUNNY 75 53 46 N10 30.02F HUNTER AAF SUNNY 75 53 45 N5 29.98F

12Z Euro maps have a 500 mb temperature max of -5C near the center mainly on the eastside.

A beast:

What about airport service on Sun/Mon at the 3 major NYC area airports? How did past comparable storms affect service?

Thanks. 1. I understand and perhaps this will bust too cool. We’ll see. 2. Let’s see if today’s update is warmer. 2. You may have not seen my edit: “Keep in mind that this was based on yesterday’s 0Z Euro ens (the latest Euro Weeklies output available til after 4PM EDT today).”
