I've looked online and can't really find a detailed article. I am in the southeast in zone 9a. Can anyone help?

Have you looked in the Farmers Almanac? I was at the grocery store and noticed a big display of them. No, seriously, maybe go on the NOAH website? Might be there.

As the weather predictions seem to change at the drop of a hat, I just follow the 10-day and monthly forecast for my city on the THE WEATHER CHANNEL's website. Just enter your city's zip code and then bookmark/favorite the site for easy toolbar clicking. https://images.search.yahoo.co...

I first saw the title of your post, and I apologize in advance....but it gave me a "huge" belly laugh!
Weather predictions!?!? For a season!?!

I don't/can't trust even a daily/weekly prediction....
My best advice would be to look at the past several seasons, and extend those out by a month, at least.
Both on the front, and end...
For the heck of it, I left an eggplant in an earth box growing over the summer... here we are .... Halloween, and the thing has been growing and producing 😳
At this point, I think it's anybody's guess!
Our climate is changing so drastically, and so quickly, that predictions, in my opinion, are fool hardy...

Winter weather prediction? You might as well read the warts on a toads body looking for an answer.
I doubt anyone can predict that. They look at trends and averages since the beginning of recorded data and then give you their best guess.

Weather people/ Meteorologists make a nice salary for being accurate maybe 10% of the time. So many of them totally blow a forecast, especially with snowstorms and then they come on television to
Make excuses why they were wrong,

I think your best bet is just to realize that we are going to have weather of some kind but to listen to a forecast and believe it, you might as well "read the bands" on a wooly bear caterpillar.
Good luck! Weather is what it is.

Any detail in your winter weather will only be predictable a few days in advance, despite the latest advances in meteorology. I tend to discard any suggestion of a winter weather event until 72 hours (3 days) in advance, and 18 hours is when forecasts start to become useful in terms of severity and timing.

completely with Baja. There really is no way to know for sure. Florida, for sure, does not experience definitive "seasons".

3 days out is about as accurate as we can get ....

But for a pretty good idea of what "might happen" ... For temperature & rainfall - there is no place better to look than here -

Unfortunately weather and climate are notoriously difficult to model (and despite working on the problem for decades, we still don't have very good models). Usually the 4-day forecast is about as good as it gets here; at least in the south east of Australia we can see most of our weather coming and so know what to expect.

In terms of a seasonal prediction, though, I suspect the best you might be able to do is look at the weather records from previous years for your particular location and identify the years where the temperatures and weather have been similar to this year. That might then give you an indication of what to expect for your upcoming winter.

Actually, I have found a pretty accurate weather blog for the west coast. Since there are no weather stations up here in the mountains, it has taken a while before I found something that gives me a sense of accuracy. It's not a daily weather site, but it is far more advanced in reporting the findings of various weather models than the usual weather sites.

The blog is authored by a climatologist and I have a sense that he works with others in his league across the nation.

On the RESOURCES page of the site, there are some east coast sources mentioned.
