Pattern Oppressive Ornery Obstinate Opposite October

It hit 35 near the house here. May have lightly froze actually, because the airport had 30.

I had it backwards in the other thread. With this setup we have, the low always ends up warmer, while the high is a bit cooler than the airport.
 
KATL had 32, which is its earliest 32 since 2001, when it occurred two days earlier. Prior to 2001, the last time Oct had a 32 or colder was way back in 1976, which preceded a very cold rest of fall and winter.

SAV had an impressive 36 this morning!

Houston, TX, had its coldest Oct low and first Oct record low since 1993 with a 35! They have had only 5 Oct lows that low or colder since records started in 1889! The 5 years: 1993, 1989, 1980, 1976, and 1917. The most similar year ENSOwise and only La Nina of the 5 was 1917. All 5 of these years had near normal or colder Nov and Dec. while 1989, 1976 and 1917 had a very cold Dec. This is not a prediction for 2017 but just an observation of the past that doesn't in itself suggest a mild Nov-Dec. fwiw.

The JB inhouse model, AKA " Pioneer " model, has a cold look to it now ! :)

Not a good sign for winter as per others. Snow near Halloween. :(
Otherwise, congratulations! That truly is a rarity in the ATL area this early. Wow! And the cold, itself, is certainly impressive. Like night and day vs this time in 2016!
It is currently only in the 50s in S GA and in N FL, as noted in Phil's map above, with sunny skies. It isn't too often to see that in late Oct in the afternoon! Looking forward to today's walk!
Upper 30s tonight much of S GA/N FL, which is almost as cold as O'Hare is this morning! Talk about direct transport of cold air!

There isn't any correlation with what is happening now, and this winter.

A colder than normal December is very reasonable this year and given how warm the first half of November will be and stereotypical NIÑA progression it may be our best chance to go below normal this winter

Sorry but DT is already saying December will be the warmest month of the winter.

More regarding this 35 low at Houston: about half of all Houston Novembers since 1890 had their coldest warmer than today's 35 low! So, this is just more evidence that this cold airmass was a pretty big deal vs climo. We could easily go 10-20 years+ before we see another so cold in October though that's not a prediction.

Edit: Median coldest in Oct since 1890 at Houston is 46.
Median coldest in Oct since 1890 at Atlanta is 38.
