Why did you mention single digits? If the polar jet dipped yo Guatemala Im talking about 20s and 30s for Miami. I bet that has happened many hundreds of yrs ago...or during the ice age. Easily.
Looking at 100 yrs of records is a joke IMO but its all we got. Now go futher, 500 million yrs ago, how about 1 billion yrs ago. Lol
To Guatemala, im pretty sure that is at least teens. Now in our current holocene period I don't think it's happened ever where Miami dropped below 20-25. Ice age probably so but keep in mind the further south you went the less of a difference between the climate of today and the ice age.
Guatemala is really deep in the tropics, the polar vortex shouldn't be anywhere near there. Guatemala City is at the same latitude as northern Brazil, northern Australia, northern Madagascar, Eritrea, southern India, Philippines, etc. You're not gonna see the Polar Vortex in Eritrea or Madagascar any time soon, and you sure as hell are not gonna see it in Guatemala
Even seeing the PV in the Yucatan Peninsula is a stretch outside of the Ice Age. Merida has a record low of 7c, that's still a bit low for the latitude, but a far cry from what you will see in Miami

Um no it's not. I'm sure you meant southern Brazil.

If I was Brazilian I wouldn't want to live nowhere near Cuiaba or Campina Grande, they're the ****tiest climates in South America. I think we can all agree that Florianopolis and Porto Alegre are a million times better
TBH, I don't see how Florida gets below normal from Canadian air masses (I know they do happen but not prolonged) so I'm willing to bet the below normal months and seasons came mostly from daytime clouds, rain, or Clear High Pressure nights and cooler waters off the coast. I don't know. Just babbling.
But there is too much resistance for that Polar Jet stream to dive farther. If it does, it doesn't last long before moving back north. For Florida to benefit from cold and even snow that Polar Jet has to dive to Guatemala and Jamaica. Maybe it did in the 1700s more but that's not happening. Just babbling again.
As far as why forecasts are showing warm this year... I believe they know there will be times where its not, but overall, that's what they are thinking because the average position of the jet will be north of there.. You have to ask the forecaster for more details.
You can thank the rocky mountains for the crappy jet stream set up, imagine how much warmer we would be with the mean winter jet position just 200 miles further north.
Canada winter forecast:
Snowy season to yield best ski conditions in years; Arctic blasts to freeze the Prairies
A snowy season is in store for some of Canada's biggest cities as winter storms dump frequent snow on eastern Canada.
Stormy weather is also in the forecast for British Columbia and the Canadian Rockies this winter, while the Prairies face bitter cold.
Frequent snowstorms to slam eastern Canada
This winter is expected to play out much differently across eastern Canada than it did last year, when mild conditions and below-normal snowfall dominated.
"The upcoming winter will likely be a stormy one across eastern and Atlantic Canada, especially during January and February," AccuWeather Senior Meteorologist Brett Anderson said.
"This pattern will lead to a higher probability of significant snowfall events from eastern Ontario through Quebec and into New Brunswick and Newfoundland," he said.
This includes some of Canada's largest cities such as Montreal, Ottawa and Quebec City.

The forecast is good news for ski resorts across the region that had a slow season last year due to mild weather and below-normal snowfall.
"I expect this upcoming ski season to be significantly better than last winter's," Anderson said.
Meanwhile, areas closer to the relatively warmer ocean water will receive more than just snow.
"Areas such as Nova Scotia and Prince Edward Island will see constant battles between snow, ice and rain," Anderson said.
Arctic intrusions to freeze the Prairies
The Canadian Prairies have already had a taste of winter with both chilly air and accumulating snow, but the worst of the season will hold off until the arrival of 2017.
The start of the season will feature occasional intrusions of chilly air, but the overall pattern will favor windier and milder conditions in cities such as Calgary and Edmonton.
"A pattern change by midwinter will likely send waves of very cold Arctic air directed into the southern Prairies for January and February," Anderson said.
The onset of each wave of arctic air may bring some periods of snow, especially in southwestern Alberta, but this will be followed up by drier conditions once the frigid air takes hold.
"Despite the arctic fronts, a persistent northwesterly flow of air during the second half of winter will suppress moisture far to the south, leading to below-normal snowfall over the eastern Prairies," he said.
Skiers to benefit from stormy start to winter in British Columbia, Canadian Rockies
A stormy pattern typical of winter will set up over British Columbia and the Canadian Rockies, delivering rounds of rain and mountain snow across the region.
"Heavy snow will quickly pile up in the mountains, which should get the western ski season off to a good start," Anderson said.
This will allow ski resorts in British Columbia and Alberta to establish a solid base early in the season that will last through the spring.
While winter may start off wet and snowy across the region, a change in the weather pattern will cause the frequency of storms to decrease heading into February and March.
This flip in the weather pattern will also bring the potential for some brief shots of arctic air all the way down to the lower mainland of British Columbia, according to Anderson.
These intrusions of arctic air may even reach areas closer to the coast, possibly making it all the way to Vancouver.
Meanwhile, the overall weather pattern this winter will favor warmer-than-normal conditions across far northern Canada, including Nunavut, the Yukon Territory and the Northwest Territories.
Omg you're right, what a **** climate. Why half a million people want to live there, the world will never know
Well half a million people do live there, whether they want to is another matter.
