Just curious where you are getting that data? I understand areas outside the city would have a freeze earlier, but according to this, http://www.srh.noaa.gov/ffc/html/groseason.txt (broken link)it looks like a freeze in Atlanta in October is very rare.

Noaa also says our average first freeze is officially November 4th. There is no way that Atlanta averages a freeze before us.

Here's a good graph for here, http://www.srh.noaa.gov/oun/climate/freeze/okc.php (broken link)

Outside of Atlanta, it can be up to 20 degrees cooler than in midtown.....over the last 13 years here's been the first freeze of the season for my town...which is 30 miles outside of Atlanta

Is this from an airport observation or someone's personal backyard? I just would find it impossible to believe that somewhere at around 33.5N latitude could average a freeze before a location at 35.5N latitude, not to mention I'm 1,200 ft above sea level so it's even higher here. Not to mention the drier air here.

Not to say that 3, maybe even 4 years out of 10 there wouldn't be a first freeze before here but then 6 or 7 of them we would have one first, giving us an earlier average. If the average at my house was around 3 weeks before the airport we would average a first freeze near October 10th, which I know is far from average. Generally I agree with our airport.

Anything is possible, I live at 40.4N latitude and our average first freeze is after many places located at a more Southern latitude, I'm by JFK too which is significantly warmer than the rest of the NYC area during winter, I wonder when our average first freeze is because Manhattan (official weather for NYC) usually freezes at least a few times before we do.

Ew... does it look like gas has been poured on the vegetation?

First frost/freeze always saddens me. Still a ways off here though... it was a balmy 65° for a low here last night.

In regards to some of the lower replies... its strange, but often places to our southwest get a freeze before we do... I guess as the cold air ushers east. Northern Arkansas and northern Oklahoma always seem to get a frost or freeze before anywhere in Tennessee does... even here in northeast Tennessee... however, we usually get it the next night.

October is one of the driest months in North GA, it's not unusual (especially in the second half of the month) to have a high of 70 and a low of 29. These were taken from the Peachtree City, GA NWS...Peachtree City is just a few miles from where I used to live and their temps are way closer than the ATL readings are. Peachtree City is located in some sort of a "valley" where the cold air drains to the bottom of the valley, helping it cool off a lot @ night. Up there we often times got our first freeze before the mountain locations @ 2,000 feet in elevation did.

Average first freeze for Dallas, TX is November 17th. (I didn't know. I looked it up.)

There used to be a weather fable in central Minnesota that the first thunder heard in spring, frost would come 6 months later.

Twice, years back, I marked on the calendar the first thunder in March and the first frost came both years 6 months later within 2 days.

I still think it's coincidence, but some old timers swear by it.

I didn't mark down the first thunder this year, so I don't know when the first frost will hit here in central Minnesota.

That's cool, I wish we had something like that to go by in NYC, our weather is just too unpredictable.

Weather in MN is much more unpredictable than in NYC
