Any analogs show up with strong El Nino’s with extraordinarily low Atlantic ACE’s the preceding tropical season?

All day, every day weather. Cool AM, warm afternoon. Throw in some rains here and there and I’m sold. -
2026-2027 Record-breaking El Nino
michsnowfreak replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
This is a trademark of climate for the east coast (particularly NYC south) and the Mid-Atlantic. Which is why I dont understand the panic from some over an expected milder than average mean over a 90 day period. Especially with the overwhelming signal for above avg precip in the east. It is different here in the Great Lakes. Big storms are usually in the 6-12" range but snow is much more frequent than the east coast. So my worry about a crummy winter is not that it wont snow- it will many times- its that in the end total snow, snowcover, and stretches of sustained/deep winter are almost always less than average in strong ninos. I imagine its similar in new England, and even though they do get massive noreasters, i cant imagine 1 storm would make or break their season as it would further down the coast. -

For me its sweaters and those cold nights with mild sunny days. The smell of the air. October is amazing in Michigan and theres really very few weather patterns that can ruin it. -
Too much UHI these days to easily secure lows in the 50s before late september. We will smash the record likely.

Absolutely a stellar day on Lake Keowee today. Current temp of 74 and overcast.

Again, we are tracking the last four El Ninos rather well as a blend. -

Roughly 20F off so far for parts of Iowa. No big deal. Only 10-15F or so by CA/OR so far. La Nina Modoki / El Nino traditional tend to favor the West Cold Fall-Spring (E Pac relatively warm v. W Pac at the equator in each case). -

pretty big east jog with Hurricane Lowell.. it now looks like the Northern islands get into the good stuff -

Would be a top ten day of the wind let up

Another .34'' from a cell that was moving southwest last evening,almost 2'' for the month.

Down to 53 here last night. Was great to sleep with the windows open and the blankets up.

With now 2 weeks of forecasts in the books the ChescoWx model has performed a bit better than the official NWS forecast every day for my backyard here in East Nantmeal Township. -

2026-2027 Record-breaking El Nino
Chinook replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
I am wondering how the El Nino may already be shifting 250mb winds, even as we've just started, in summer. Obviously, we'll expect lots of subtropical jet in winter. As for now, I used the HISTDATA from NOAA to plot this... it's essentially the same as NCEP/NCAR reanalysis but it lacks some capabilities. Anyway, the 250mb zonal winds have been more westerly than average for some of the E Pacific, into southern Mexico, then out to the Atlantic. You can see the evidence of a ridge over the central USA. Now, we know El Nino tends to have these situations where the wind shear is quite high for the Atlantic hurricane season and squash that. But here's the question: if the 250mb winds were so westerly, why has the E Pacific generated some strong storms? Of course, on here, there's the Hawaii area ,which has had a hurricane this summer (and now a couple more storms by Hawaii), with the more-easterly-than-average winds as shown. -

After being pretty flat in August/first few days of Sept, the relative 3.4 OISST anomaly has risen sharply the last two days: Sept 4th relative 3.4: +2.254 Sept 6th relative 3.4 anomaly: +2.429, a rise of 0.175 in just two days…that’s the most rapid two day rise on this entire chart as it is the most rapid two day rise since June 3rd-5th, which is not on this chart: -
Dipped below 60 for the first time at my location since mid-June. Very cool feel this morning but it's rebounding quickly through the low 80s right now. Great windows open weather to let some of this dry air flow in.

The daily WCS PDO has risen back substantially the last 7 days ending yesterday with it up to -0.9, the highest since way back on July 2nd, vs ~-1.65 one week earlier: -

Hello all. The ChescoWx website https://chescowx.com has had a major overhaul and it is now live! Everything is interactive now. You can pull up climate trends unique to the Philly burbs of Chester County PA for any measure, look at a single station or the whole county, and compare us against Philadelphia, Reading, or Allentown airports. There are all time records, decade summaries and climate trending options going back to the 1870's, top snowstorms, snow by season and even a White Christmas history. Every trend also tells you whether that trend is statistically significant or simply weather noise. Behind the enhanced website sits 42 Chester County area stations and more than 458,000 daily observations going back to 1871. Take a look and let me know what you think and what we are missing you would like to see or be able to view interactively. Thanks! Paul
