2026-2027 Record-breaking El Nino

I was asked to compare PHL Airport vs East Nantmeal Twp. In the western philly burbs of Chester County PA for climate since 2004. (see full panel below) Summer afternoons: PHL’s highs run 5.4–6.3°F warmer from June through September. Against the whole county the gap was mainly at night; against East Nantmeal it’s mainly in the daytime. That fits what the siting check found: my fan-aspirated Davis VP2 records cooler highs. Elevation adds to it. Overnight lows: PHL is warmer every month, from 2.8°F in April to 5.1°F in August. Rain and snow: Precipitation: East Nantmeal gets 50.35" a year to PHL’s 45.56". It’s wetter in most months, especially July (5.62" vs 4.66"). Snow: East Nantmeal averages 35.8" a season against 22.7" at PHL, about 58% more. EN had more snow than PHL in all 22 seasons. February shows the biggest difference: 13.4" vs 8.4". Is the temperature gap widening? Yes. It has grown about 0.46°F per decade, mostly in daytime highs (+0.64). PHL warmed about 1.0°F per decade over these 22 years, against 0.55 at East Nantmeal. I will post up Chester County as a whole later. Let me know if any questions. Thanks!

Lake effect is a function of Arctic air moving over the warm lakes. With a flood of pacific air lake effect is shut off. One thing the warm air should do is prevent cooling and ice formation. If we do see Arctic intrusions later in the season lake effect would be on the table and later then climatology. .

hm not aware of any teleconnectors for the latter half of November but from 7th to 16th or so, that's not really a cold pattern. The teleconnectors for that earlier time range are indeed -AO/+PNA ...but this is one of those situations where the numerology is lying about the super synoptic aspects, and the actual mean spatial layout. The +PNA is almost all being caused by strong neg anomalies NE of Hawaii...but the flow subtending down stream over the Conus is very zonal... so it's misleading to some degree. As to the -AO...that's suspicious too. The actual orientation of the heights/contouring show an annular structure about the AO domain, but the domain itself happens to have modest positive anomalies. That's the problem with using strictly the geopotential anomalies to compute the orthogonal/eof derivatives, particularly when the heights everywhere are about a coffee break from kicking off the super extinction event heh seriously, it's closer to an annular flow type just happening to be above normal.

Wonder if anbody stopped and wondered what will happen if they issue a stop-payment on their subscription?

maybe warmer? gw/cc

Spectacular mid fall day today.
-
I guess a few post-frontal days in the 40's could be considred "cold" if your avg is 52
-
1877-78 incoming?
-
Hopefully you miss!

-
clouds over the top of RMNP but not snow

-
4.5 hours leaf blowing today , absolute disaster
-
Is Burt Reynolds with you there?
-
A warmer Canada is colder than Tolland.

- Today
-
effects of the ssw already being felt, normally models would come out earlier starting the second week of november
-
Correct - plus all these above average temp months in a row and this abnormally long stretch of spring/summer like weather the last couple of weeks is giving some folks a false sense of security that EL NINO will protect us from the cold and snow well into winter..............
-
Long range gfs brings down the cold
-
December is so far away . No one has a clue yet that far. Long range forecasting hasn't been right in years.
-
Models come out earlier tomorrow
