What does the (really +13) mean? thanks        I FIND THE GFS SO BAD ON THE T,  I JUST ROUTINELY REMOVE 5 DEGREES FOR AN 8 DAY PERIOD.      THE ERROR SEEMS TO BE + ALL THE TIME.       56/69 WAS THE ACTUAL, SO 51/64 IS PROBABLY MORE REASONABLE.

The Euro Monthly Guidance is very warm. Hopefully, it won’t verify.

There is potential for this winter to blow 2011/12 out of the water regarding the warmth.

Imagine seeing widespread blooms in Dec/Jan, insane stuff. 

There's also a chance we go through some odd snowy/cold periods.

70° now at Newark. They need to reach 5 to get into the November top 3. 2015 was the last November with 5 days reaching 70°.

1938 was a very interesting month, yesterday I was looking at the top 30 warmest NOV's at Philly for the most 70 degree days & that year is #2 with 8 such days. What's cool is the first 23 days of that month averaged 54.2 degrees which is 5.4 degrees above average & on pace for the warmest NOV on record however the last 7 days of the month averaged 30.4 degrees representing a -13.2 degree departure. Additionally over the last 7 days Philadelphia recorded 11.2" of snow making NOV 1938 the 2nd snowiest NOV on record.

Looking at Newark the warmth wasn't as pronounced over the 1st 23 days, 51.8 degrees (+3.8), but like Philly the cold & snow at the end of the month was extreme. Temperature wise the final 7 days averaged 28.4 degrees (-14.5) & over that timeframe Newark recorded 14.2" of snow making NOV 1938 the snowiest NOV on record.

Temperatures rose into the upper 60s with some lower 70s across the region today. Tomorrow could be several degrees warmer in many parts of the region.

Widespread record warmth again prevailed in the western half of the United States from the Southwest into the Northern Plains. Records included:

Bismarck: 77° (old record: 76°, 2016)
El Paso: 85° (old record: 82°, 1916, 1924 and 1945)
Helena: 76° (old record: 68°, 2001) ***New November Record***
Missoula, MT: 69° (old record: 67°, 1934 and 2012)
Montreal: 69° (old record: 66°, 1988)
Phoenix: 99° (old record: 93°, 2007) ***New November Record***
Rapid City: 79° (old record: 77°, 2016)
Scottsbluff, NE: 81° (old record: 79°, 1914)
Tucson: 94° (old record: 92°, 2009) ***Tied November Record***

The core of the exceptional warmth that has been setting records across the Plains States into the Great Lakes region will gradually shift eastward. This weekend into the start of next week, it will be focused on the Great Lakes Region and southern Ontario and Quebec.

As that happens, a colder than normal pattern will become established in the Western third of the United States. By the end of the weekend or early next week, the Northern Rockies could experience another significant winter storm.

In the Middle Atlantic and southern New England areas, an extended period of above and much above normal temperatures will likely continue until at least near mid-November. The first half of the month will likely wind up much warmer than normal. The probability that November will have a mean temperature of 50° or above in Central Park has increased. The last time that occurred was 2015.

The ENSO Region 1+2 anomaly was -1.1°C and the Region 3.4 anomaly was -1.7°C for the week centered around October 28. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.98°C and the ENSO Region 3.4 anomaly has averaged -1.30°C. La Niña conditions will likely prevail at through the winter.

The SOI was -5.79.

Today, the preliminary Arctic Oscillation (AO) figure was +3.694. That is the highest AO figure since March 24, 2020 when the AO was +3.968.

On November 4 the MJO was in Phase 7 at an amplitude of 0.748 (RMM). The November 3-adjusted amplitude was 0.748.

Since 1950, there have been five cases where a La Niña developed during June-July-August or afterward following an El Niño winter. 4/5 (80%) of those cases saw a predominant EPO+/AO+ winter pattern. The most recent such case was 2016-17. 9/10 (90%) of the La Niña winters that followed an El Niño winter featured a predominantly positive EPO. A predominant EPO+/AO+ pattern is likely for winter 2020-21. It is likely that the Middle Atlantic and southern New England areas will see a warmer than normal winter with potentially below normal snowfall. The November run of the seasonal European guidance suggests that winter 2020-21 will likely be warmer to much warmer than normal in the region.

Morning thoughts...

Today will be partly sunny and unseasonably warm. High temperatures in the region will likely reach mainly the upper 60 and lower 70s. Likely high temperatures around the region include:

New York City (Central Park): 68°

Newark: 71°

Philadelphia: 71°

An extended period of warmer to much warmer than normal conditions is underway.

The new Euro seasonal is as ugly as it gets. Dec-Mar are a total disaster

If that’s the case, awful but all the better. A train of teases or nearby getting heavy snow and 33-34 rain here are the worst. Let ‘em all cut for Buffalo then and have it be warm here. Hopefully it’s not the cutter then days of bitter cold and dry before another cutter. Ninas are famous for that here too.

I bet we see allot of gradient storms like the last few winter with low centers heading along 95 and snow north of 84. I think we could pull off a wintery stretch with some transient blocking. If I had to guess it’s when we don’t want it, sometime in March.
