Tuesday Snowfall

Officially 0.6" of snow fell Tuesday at the Twin Cities airport from the system that moved through the region, but heavier totals fell as you went north - particularly along portions of the North Shore. A foot of snow was reported near Hovland with 11" in Grand Portage.


Historical Probability Of A White Christmas

With the new 1991-2020 climatological data in place, the probability of a white Christmas map has been updated! Here's a look nationwide at that probability, and you can view an interactive map to see your local probability by clicking here. Remember a white Christmas is classified as there being at least 1" of snow on the ground. With the new climate data, the Twin Cities historically has a 74% chance of a white Christmas, increasing to 77% in St. Cloud and 92% in Duluth. Rochester has a 66% chance historically and Mankato has a 69% chance.


Thursday Weather Outlook

If your holiday travels start to take you out of town on Thursday, we currently have little to no concerns in the forecast. Some models are showing a very slight chance of a few snowflakes or freezing precipitation in the early morning hours, but most of the day should be dry and sunny. Morning temperatures will be in the low to mid-20s with highs in the upper 30s.

There will be a better chance of snowflakes across northern Minnesota as we head through the morning and midday hours Thursday, with up to 2" possible in northwestern portions of the state. Sunnier skies are expected as you head south. Temperatures range from the 20s up north to the low 40s in southwestern Minnesota.


Christmas Eve and Christmas Day Weather Forecast

Christmas Eve looks to be quiet in the Twin Cities as temperatures climb into the low 40s with partly cloudy skies. We will watch the chance of some wintry precipitation (snow or ice) across portions of northern Minnesota as a system passes just north of the border.

Temperatures will be chilly as Santa makes his rounds Friday Night, and as you wake up Saturday it'll range from below zero in northwestern Minnesota to the 20s in southeastern Minnesota.

For your Christmas Day, we are watching the potential of snow! A system looks to bring snow into western Minnesota by the midday hours, moving into the metro by the mid-afternoon timeframe. This snow will move out Saturday Night. Some models indicate the potential of at least 2" in some locations, but there is a lot of uncertainty in the overall precipitation forecast from this weekend into early next week so it'll be something to keep an eye on the next several days if you have travel plans over that timeframe.


Antidote to Winter Blues: Play Outside
By Paul Douglas

Winters are warming, but Minnesota's Frostbite Season is still intimidating to most of the planet. My new daughter in law grew up in New Mexico - she's moving here with our youngest son, who is giving her tips on appropriate winter gear.

Experts remind us to get outside as much as possible to beat the winter blues. Tuesday we checked out amazing holiday lights at the Minnesota Landscape Arboretum in fresh, 14-degree air. She was dressed for the weather and loved it. Well done Karla!

Thawing temperatures arrive today and Christmas Eve with a shot at a little ice this morning and 40 degrees Christmas Eve.

A coating of snow Saturday gives way to a more impressive system Sunday into Monday; maybe a few inches of snowy fun by Monday morning. A few more snow events are likely next week, and some models print out 10-20" of new snow for central and northern Minnesota by New Year's Day.

No, cold fronts have not been canceled. The first subzero lows of winter are possible by New Year's Eve at MSP. Bring it.

National Weather Forecast

A mess of weather will continue out in the western United States as we head through Thursday with rain and snow and even a few thunderstorms. We will also be tracking some snow and mixed precipitation from northern Minnesota to the Great Lakes and into portions of the Northeast.

Several feet of snow are expected to accumulate through Christmas Eve across the Cascades, Sierra, and into the northern Rockies. Meanwhile, over 3" of rain could fall along portions of the West Coast and in the Sierra at lower elevations that don't change over to snow.


A record 20.73 inches of rain fell in a day during extreme Tennessee floods, report shows

More from the Nashville Tennessean: "A record-shattering 20.73 inches of rain fell in 24 hours in Humphreys County, triggering extreme floods that killed 20 people on Aug. 21, officials said. The National Weather Service Nashville confirmed the total on Monday. Early estimates topped out rainfall at 17.03 inches in Humphreys County that day, but further investigation into a measurement at a wastewater treatment plant in McEwen revealed the new record-high total, NWS meteorologist Krissy Hurley said. She also said it is the highest 24-hour rainfall record for any state not touching an ocean."

A perfectly preserved dinosaur egg highlights link to modern birds

More from NBC News: "A 66-million-year-old fossil of a complete baby dinosaur in its egg, apparently just a few days before it would have hatched, shows the remarkable similarities between theropod dinosaurs and the birds they would evolve into, according to a study published Tuesday. The fossilized bones of the embryo, named "Baby Yingliang" after the museum in southern China where it was discovered, can be seen curled up inside its 6-inch elongated eggshell and looking almost exactly like a modern bird at that stage, although it has tiny arms and claws rather than wings. Fion Waisum Ma, a paleontologist at the University of Birmingham in the United Kingdom, said the head is particularly striking in its similarity to the head of a newly hatched bird — a resemblance heightened by a beak that was a feature of the dinosaur species, called oviraptorosaur. Ma is one of the lead authors of the fossil study published in the journal iScience. Scientists from China, Canada and elsewhere in the U.K. were also involved."

'We really don't have a plan': Biden's climate promises are sunk without Build Back Better, experts say

More from CNN: "Multiple independent analyses have found President Joe Biden simply can't hit his goal of cutting greenhouse gases by 50% by the end of the decade without the clean energy provisions in Build Back Better, the President's signature economic and climate legislation. After West Virginia Sen. Joe Manchin torpedoed the bill, experts say these goals are ever more out of reach — with devastating consequences. "Without this bill we really don't have a plan to tackle the climate crisis in the US," said Leah Stokes, a senior policy adviser at Evergreen Action and climate expert at the University of California, Santa Barbara. "Cutting carbon pollution 50-52% is a really big goal, it's what's necessary, but it's not going to happen without significant federal investments.""
