Oh Canada, that’s coldddd!
What did we ever do to deserve this?
On a serious note, that’s one of the most elongated north-south Arctic intrusions I can remember seeing!

#AtmosphericRivers don't just impact the West Coast—these powerful weather phenomena are bringing floods to the central U.S. @cw3escripps.bsky.social director Marty Ralph spoke with @amyjeangraff.bsky.social of @nytimes.com on the need for expanding AR research across the country.
One of the Weather World’s Biggest Buzzwords Expands Its Reach
To many, atmospheric rivers are a West Coast phenomenon. But they’re also responsible for the devastating flooding that hit the Central United States in early April.

What happens to #AtmosphericRivers when they interact with #MarineHeatwaves?

Our new paper now out in @natureportfolio.nature.com Scientific Reports provides an answer. We assessed the impact of “the #Blob” on landfalling atmospheric rivers on the North American west coast. Here is what we found 🧵

Exceptional blocking with warm record in GREENLAND
Min 5.5 Nuuk, 5.0 Maniitsoq .
NOVEMBER HOTTEST NIGHT ON RECORD

A powerful arctic blast will send freezing temperatures till Northern Florida, BUT that's BY NO MEANS a record cold event:
Early November 1976 was far worse with 21F and 6 freezing days

A series of shortwave troughs and #AtmosphericRivers are forecast to impact the US West Coast starting around mid-week and potentially continuing into next week.

A family of #AtmosphericRivers are forecast to bring heavy precipitation to the US West Coast this week, with the potential for additional landfalling AR activity next week.

After an extraordinary holiday heat dome across the US, get ready for a Polar Vortex Invasion next week! Cold air will surge deep South w/ 20s in the SE and 30s far into #Florida. The airmass won’t be super #cold up north. Instead the South will get the brunt, 15-20° below normal!

Code Yikes!

Another month, another new record for the 36-month running average for Total Column Precipitable Water in the Northern mid-latitudes.

Pineapple Express will deliver a barrage of tropical fire hoses directed at the US West Coast over the next two weeks. Pockets of 12-18” of rain and flash flooding. The first round hits the Seattle Area early this week, as rivers are already at historic levels. Be ready to take immediate action.

Historic flooding in MI and WI: 5 rivers are at record flood or predicted to be (blue dots); 6 other rivers already set record highs in MI. Mullet Lake in MI is 2' above its record high; the dam at its E end above Cheboygan is just 5" from overtopping; 3 other MI dams are also close to overtopping.

Why is New Year’s so #cold in #Florida? It’s simple. There’s a big mountain of warm air (relative to normal) over Greenland and Eastern Canada. That is blocking cold air from moving east through Canada and instead it’s being rerouted (like a detour) into the Deep South.

We posted a quick summary of the #AtmosphericRivers that influenced precipitation across the US West Coast and led to heavy precipitation in CA this past week. Check out more here: cw3e.ucsd.edu/wp-content/u...
