Another Storm This Week
After a quieter Monday and Tuesday, another storm system will move into town Wednesday through Friday with rain and snow potential across the region. The heaviest snowfall looks to stay across the northern half of Minnesota. Stay tuned...
Precipitation Outlook
The extended precipitation outlook through the weekend suggests some decent amounts across the eastern part of Minnesota and into Wisconsin. Some locations across the southeastern part of the state could see tallies nearing 1" or more, including near the Twin Cities.
Snowfall So Far This Season
Snowfall amounts are quite impressive across the region with several locations running well above average. Duluth is closing in on the snowiest season on record and could likely break that record later this week, while the Twin Cities is at the 3rd snowiest season on record, nearly 40" above average. Note that Bismarck has seen nearly 100" of snow as well and is less than 2" away from the snowiest season on record there.
Snowiest Season on Record at NWS Twin Cities
Interestingly, the NWS Twin Cities, located in Chanhassen has surpassed the 100" mark this season, which is officially the snowiest season on record there. Note that records only date back to 1995, when they moved into that particular office location. Regardless, more than 100" this season is a lot of snow!
2nd Snowiest Season on Record in Duluth
Brainerd, MN and Bayfield, WI has also seen their snowiest seasons on record, while Duluth, MN is less than 0.5" away from the snowiest season on record! There's more snow in the forecast for northern Minnesota and that record could be broken by Thursday.
3rd Snowiest Season on Record in Minneapolis
With this weekend's storm now in the books, the MSP Airport has seen more than 90" so far this season, which is the 3rd snowiest winter season on record. We need less than 5.0" into the 2nd spot and less than 9" to get into the top spot. If you're wondering, the latest measurable snow (0.1") on record at MSP was on May 24th set in 1925. The snow season isn't quite over just yet... Stay tuned.
Flood Outlook
According to the National Weather Service, a number of river gauges around the region will be entering flood stage here over the next few days. Some spots will be at Moderate and even Major flood stage, which could cause issues in a few flood prone communities.
Major Flooding Expected in Stillwater
Here's the river forecast for the St. Croix River at Stillwater. Moderate flooding was occuring on Monday with Major flooding likely as we head through the rest of the week. Note that this could be the most significant crest since March 31st of 2019 and could potentially be the 6th highest crest on record there! If the crest gets to 90ft, HWY 95 between Afton and Bayport begins to flood. Lakefront Park bathhouse in Hudson affected.

Earth just had its second-warmest March on record
"Polar sea ice coverage for March 2023 ranked second smallest recorded. The planet continued its exceptionally warm start to the year with its second-warmest March on record. Global sea ice coverage also felt the heat, with sea ice running at its second-smallest extent since records began in 1979, according to scientists from NOAA's National Centers for Environmental Information. Below are more highlights from NOAA's latest monthly global climate report: Climate by the numbers March 2023 The average global land and ocean-surface temperature for March was 2.23 degrees F (1.24 degrees C) above the 20th-century average of 54.9 degrees (12.7 degrees C), ranking as the second-warmest March in the 174-year global climate record, behind March 2016. March 2023 also was the 47th-consecutive March and the 529th-consecutive month with temperatures above the 20th-century average. Looking at the continents, Asia had its second-warmest March on record, and South America and Africa each had their fourth-warmest. Europe saw its 10th-warmest March on record, while North America had a warmer-than-average March, but it did not rank among the top-20 warmest on record."
Status of Spring
"April 17, 2023 - Spring leaf out continues to spread north. Spring arrived several days to weeks earlier than average (the period of 1991-2020) in much of the Southeast, lower Midwest, and mid-Atlantic, then slowed across the northern Great Plains and lower Midwest. In the past week, spring has picked up speed, arriving days to weeks early across the upper Midwest and northern Northeast. Salt Lake City, UT is 22 days late, Green Bay, WI and Portland, ME are 3 days early, and parts of Michigan's Upper Peninsula are 12 days early. Spring bloom has also arrived in southern states, days to weeks early in the Southeast, and days to over a week late in the Southwest. Albuquerque is a week late, New York City is 11 days early. How typical is this year's spring? Darker colors represent springs that are unusually early or late in the long-term record. Gray indicates an average spring. Parts of the Southeast, lower Midwest, mid-Atlantic, and New York City area are seeing either the earliest spring leaf on record or a spring that only occurs once every 40 years (dark green). Parts of the West are seeing a spring that only occurs this late once every 40 years (purple). Spring bloom is latest on record across parts of the Southwest including California and Arizona, and earliest on record in parts of the upper Southeast including Tennessee, Georgia, South Carolina, and North Carolina."

An April Outlook That Should Be Censored
By Paul Douglas
April appears to be malfunctioning. I've tried kicking the Doppler, to no avail. Your options are upper 80s or slushy snow. April is the New March.
Should Minnesota meteorologists refrain from using the s-word [snow] until October? For mental health purposes, absolutely. Brainerd has already seen the snowiest winter on record with 85.3". Third snowiest at MSP (90.3") and Duluth (135.1") will shatter the record for snowiest winter on record since 1885. From drought to flood in the twinkle of an eye.
Expect rain today with a few T-storms and wet roads locally. Rain ends as a little slush in the metro late Thursday, but models print out plowable (5-8"+) amounts of snow for Mille Lacs, Brainerd, Walker and Bemidji by Friday. Is there a therapist in the house?
Windblown flakes and sprinkles Friday give way to spurts of chilled sunshine over the weekend with highs near 40F. But the sun is too high in the sky for cold weather to hang on for long. Models show 50s later next week and 60s by late April. Whew...
Extended Forecast
WEDNESDAY: Rain, few T-storms. Winds: E 15-25. High 49.
WEDNESDAY NIGHT: Chance of t-showers overnight. Winds: E 5-10. Low: 42.

FRIDAY: March flashback. Wind-whipped flakes. Winds: W 15-35. Wake-up: 32. High 38.
SATURDAY: Peeks of sun, jacket-worthy. Winds: NW 15-25. Wake-up: 30. High: 41.
SUNDAY: Partly sunny and brisk. Winds: NW 10-15. Wake-up: 26. High: 44.
MONDAY: Cool sunshine. Winds: NE 7-12. Wake-up: 29. High: 50.

Climate Stories
"Electric Car Production Will Accelerate after EPA's Historic Tailpipe Emissions Rules"
"The tailpipe emissions rules EPA proposed Wednesday are the sticks to Congress' carrots, providing the clearest view yet of how the agency plans to leverage the hundreds of billions of dollars lawmakers have pumped into clean energy and infrastructure. EPA built its two market-transforming rules on top of generous incentives in last year's Inflation Reduction Act, or IRA, and the 2021 bipartisan infrastructure law. That resulted in the agency proposing the most aggressive restrictions in U.S. history on the carbon, smog and soot emitted from compact cars all the way up to long-haul trucks. It's a pattern EPA will likely repeat when it releases its power plant carbon rules later this month."

"The clean energy milestone the world is set to pass in 2023"
"This year, the world is predicted to pass a critical turning point in renewable energy. Greenhouse gas emissions from the power sector, the largest source of the world's emissions, are expected to fall for the first time, according to London-based think tank Ember. That's despite the fact that the world's demand for electricity is still growing. Emissions are set to fall because expansion in renewable energies such as solar and wind is outstripping that growth in demand. It's a crucial moment in the effort to tackle climate change, and the report, written by Małgorzata Wiatros-Motyka, senior electricity analyst at Ember, and colleagues, argues that we are fast approaching a positive "tipping point" in the effort to curb climate change. "This marks the point where power sector emissions stop rising," Wiatros-Motyka and her colleagues write. "Clean power can actually go to replacing fossil fuels, instead of just meeting rising demand."
"Global wind energy will exceed 1 TW by the end of 2023"
"Global wind energy will pass the 1-terawatt (TW) threshold for installed capacity by the end of 2023, according to the newest market outlook from Wood Mackenzie. Luke Lewandowski, Wood Mackenzie research director, said: After needing more than 40 years to reach one TW of installations, the wind industry will reach the next TW of installations within the next eight years, a significant acceleration of growth. WoodMac forecasts that annual wind capacity additions in China overall will average a massive 80 GW and make up 50% of new capacity globally over the next ten years. European countries will add more than 343 GW of offshore and onshore wind capacity over the next decade; offshore wind will account for 39% of new capacity. Onshore growth in emerging Eastern European markets and the repowering of older wind farms in markets such as Germany and Spain will also drive wind energy adoption."
"Never-before-seen 'crystal-like matter' hidden in a chunk of fossilized lightning is probably a brand new mineral"
"The potential new mineral was discovered in a chunk of "fossilized lightning," or fulgurite, that was left behind when a tree in Florida was struck by lightning. A potentially brand new mineral may have been hiding inside a chunk of "fossilized lightning" from Florida, scientists have revealed. "We have never seen this material occur naturally on Earth," Mathew Pasek, a geoscientist at the University of South Florida, said in a statement. "Minerals similar to it can be found in meteorites and space, but we've never seen this exact material anywhere." The fossilized lightning chunk, or fulgurite, was created when lightning struck a tree near New Port Richey. Fulgurites form when powerful lightning bolts discharge through the ground, which melts and fuses any nearby soil, sand, rock and organic debris into a singular metallic-looking lump."
