Whew, that was close!
But it looks like Iguana’s will be Marked Safe, barely, on Friday, as temps fall just shy of critical levels. But, if you ask me, this guy is a little too overconfident.
Iguana’s live mostly South of the Sunshine Skyway...1/

Two miles of ice core on the shelf at our national ice core facility in Lakewood, Colorado. The WAIS Divide core from West Antarctica is a 3400m long (deepest US core, 2nd deepest ice core ever) 68,000 year old record of high resolution climate.

Going Cold Turkey by Week’s End across the Eastern US!
Until then the warmth will persist here in Florida and the Southeast.

Fly-by Cold!
After a long stretch of very warm weather, a chilly blast arrives Friday! AM Wind chills in the 30s and 40s for Central and North Florida. Highs on Black Friday will struggle to get out of the 60s.
In true FL style, the chill will last 24 hours.
Don’t blink!

Sorry Florida… No Rain Fo You!
(Well, techincally there will be a few drops over the next 2 weeks.)
And that’s too bad because we could really use a lot! Getting deeper into drought as the dry La Niña winter takes hold.

We have a tendency in weather to focus on the shiny object. Right now that shiny object is the cold, which is elusive.
The reality: over the past week, the US has seen a Blow Torch. 100s of heat records to just a dozen cold. The heat continues through midweek.

While the entire weather enterprise - it seems - is focused on extreme US cold - which may take weeks to materialize, the country has been roasting. Over the past 7 days 100s of heat records have been broken, and the nation as a whole has been ~4F above normal. +20F near the Ark-La-Tx!!

Here’s a very simple & limited comparison 5 days out of the best and worst forecasts for #Melissa on left and the season on right.
Not to pile on the GFS/ American model, but it had a bad season overall... 1/

Big Polar Plunge across Europe as the jet stream takes a nose dive! Temps 10-20C below normal! Lots of snow in the mountains!!

While the weather world is focused on the expected big pattern shift and possible Arctic Outbreak after the Thanksgiving’s Turkey 🦃 deep fry, the nation’s middle is frying right now! Summery today at 25 degrees above normal, and 40 record highs!Dozens more through week’s end… (records via CoolWx)

This is how our forecast Polar Vortex Breakdown - Sudden Stratospheric Warming - plays out over the next 2 weeks ~20 miles aloft, as per the GFS model. This top and bottom comparison is a good visual on how breakdown occurs…

Fee-fi-fo-fum the Polar Vortex is about to come undone! 😳
That typically means wild weather/ big time cold to follow!
But wait, don’t head for the hills just yet. I assure you the sky won’t fall.
Seriously though, you’re bound to hear about this, and the science is fascinating, so let’s dig in… 1/

I missed this study during the summer. It’s interesting. Using NASA Grace data: Two main points about fresh water depletion and sea-level rise.

Are farting cows climate criminals?
Sounds hard to believe, but Livestock (farmed animals) are responsible for about 10% of global warming!
However, the farting part… that’s not quite right.
(For the record, I’m not a cow hater. In fact, I like them so much, I don’t eat them.)

Pound for pound, this heat dome is every bit as impressive (or more) as the cold snap. Even more records. But since the temps are comfortable, it won’t make much news.

You thought our Deep South record cold was impressive? Take a look at this record heat! 100 plus record highs today across the Nation’s middle. Temps in some of the Northern Plains besting Florida!
Pretty darn comfortable for November.

The cold snap made the headlines, but the warmth in the nation’s middle now will fly by the radar.
70 heat records in jeopardy today (record highs and record warm lows) with temps 20-30 degrees above normal.
A pleasant break before the winter chill sets in.
