It hasn't been record cold here, but it's been consistently cold, teens and colder, since early December. I'm beginning to understand why people become snowbirds in senior years! Wish I could afford to be one!greatunclebill wrote:tuesday morning was +14 degrees in mobile alabama. this was an all-time record low. brrrrrrrrrrrrr......... i grew up in northern MN where it got very very cold. i don't miss it even a little bit.

All 50 of America’s states recorded temperatures below freezing at some point on Tuesday and even the polar bear at Chicago zoo spent most of the day indoors, as bitterly cold air gripped the country

Due to these jet stream issues we have had more moist air coming from the coast so we already have had our normal winter's accumulation of snow back in mid December.Snow and ice are disappearing from the Arctic region at unprecedented rates, leaving behind relatively warmer open water, which is much less reflective to incoming sunlight than ice. That, among other factors, is causing the northern polar region of our planet to warm at a faster rate than the rest of the northern hemisphere.
Since the difference in temperature between the Arctic and the mid-latitudes helps drive the jet stream (which, in turn, drives most US weather patterns), if that temperature difference decreases, it stands to reason that the jet stream’s winds will slow down. Why does this matter?
Well, atmospheric theory predicts that a slower jet stream will produce wavier and more sluggish weather patterns, in turn leading to more frequent extreme weather. And, turns out, that’s exactly what we’ve been seeing in recent years. Superstorm Sandy’s uncharacteristic left hook into the New Jersey coast in 2012 was one such example of an extremely anomalous jet stream blocking pattern.
When these exceptionally wavy jet stream patterns occur mid-winter, it’s a recipe for cold air to get sucked southwards. This week, that’s happening in spectacular fashion.
I suggested to a colleague we restart the coal plants in Ontario (we recently shut the last of them down -- the majority of our power is nuclear) and make a nice cozy CO2 blanket over the province. He thought that was a good idea. He had just returned from Iroquois Falls in the far north of Ontario and showed me a picture he took earlier this week of an outdoor thermometer: -45C (-49 F) without the wind. Yes, people live there. Not me though.Stormynights wrote:I seems like it is just a matter of being prepared. In colder areas you have to be prepared because you know it is going to be cold. In warmer areas you don't expect it to happen. We have been preparing for global warming.
I lived in Hammond (50 miles NW of NOLA) for 15 years. One of my biggest worries was wearing out the thermostat switching it back and forth from heat to cool during the February to April time frame!Kiralynx wrote:We had temps in the 20s with wind chill in the teens here in New Orleans.
We are immensely glad to have our whole house generator, because (not this cold snap, gut two others) there had been two night-time power outges. One due to cold and the other due to someone running their car into a power pole.
'Course, you realize, that in another four months, we'll probably be b--ching about the heat!
