Spring Leaf Index

If you look close, so of your backyard trees and bushes have actually started to show signs of spring leaves emerging. According to the NPN, this is happening nearly 2 to 3 weeks earlier than normal across Minnesota and Wisconsin.

"How do you know when spring has begun? Is it the appearance of the first tiny leaves on the trees, or the first crocus plants peeping through the snow? The First Leaf and First Bloom Indices are synthetic measures of these early season events in plants, based on recent temperature conditions. These models allow us to track the progression of spring onset across the country. April 20, 2021 - Spring leaf out continues to spread north across the country. After arriving early in southern parts of Southwest and Southeast states, cold temperatures halted the progress of spring leaf out for several days across the northern part of the Southeast, Southern Great Plains, and mid-Atlantic. Spring leaf out is now arriving days to weeks early across the northern Great Plains, Midwest, and Northeast. Spring bloom has arrived in Southwest and Southeast states. Spring bloom is patchy, with much of Texas days to weeks late, while parts of Kansas, Tennessee, Missouri, Illinois and Indiana are days to weeks early."

Extended Temperature Outlook

Here's the ECMWF & GFS extended temperature outlook for Minneapolis over the next couple of weeks. Temps will be running a little cooler through the weekend, but temps will likely rebound into the 60s next week and into the 70s during the first few days of May.

8 to 14 Day Temperature Outlook

According to NOAA's Climate Prediction Center, the 8 to 14 day temperature outlook shows warmer than average temps for early May across the Southern and Southwestern part of the nation.

Aprils Are Suddenly Character-Building
By Paul Douglas

I'm trying to convince my (new) daughter-in-law, who lives in Washington DC, that Minnesota weather is nothing to be scared of. Without turning into Pinocchio with a Doppler. "Well, Minnesota's lake-worthy, cabin-happy summers more than make up for any challenging winters!" That, and an opportunity to upgrade your winter wardrobe!

Lately I've been smiling through clenched teeth. Whatever happened to April? 26"of snow fell in April, 2018 - so today's sloppy mix won't be nearly as controversial. A few inches of slop may accumulate over southwest Minnesota, but no need to sound the sirens.

The pattern is more erratic and volatile than ever. A March-like Sunday gives way to a shot at 70FMonday, in fact daytime highs most of this week will be at or above 60F. Average, imagine that.

T-storms prowl the state Monday and Tuesday, but the latter half of the week looks dry, with temperatures mellowing into the 70s for the first Saturday in May. Ah, May. As in, it MAY finally warm up for good. Keep the faith.

0.9 Day Until Full "Pink" Moon

"10:32PM April 27th - The grass pink or wild ground phlox is one of the earliest widespread flowers of the spring. Other names for this month were the Full Sprouting Grass Moon, the Egg Moon, and — among some tribes on the east coast — the Full Fish Moon, when shad came upstream to spawn."

What's in the Night Sky?

"At nightfall – April, 25, 2021 – look eastward to view the bright waxing gibbous moon and the star Spica over the horizon. First look for the moon, and that nearby bright star will be Spica, the brightest star in the constellation Virgo the Maiden. Spica serves as a prime example of a 1st-magnitude star; in other words, it's one of the brightest stars in our sky. You should have no trouble picking it out, even in the glare of the waning gibbous moon. Spica is a blue-white gem of a star, and, for stars, color indicates the star's surface temperature. Spica's blue-white complexion reveals that its surface temperature is extremely high (39,860 degrees Fahrenheit, or 22,127 degrees Celsius). In contrast, our yellow-colored sun has a much cooler surface (only 9,980 degrees F, or 5,527 degrees C). The surface temperature of an orange star, such as Antares, is even cooler (7,300 degrees F, or 4,038 degrees C)."

"Renewables could displace fossil fuels to power the world by 2050, report claims"

"Solar and wind energy could replace fossil fuels entirely to become the world's power source by 2050, a new report has claimed. Published Friday, the report from thinktank Carbon Tracker also predicted that if wind and solar power continued on their current growth trajectory, they would push fossil fuels out of the electricity sector by the mid-2030s. Current technology gave the world the power to capture 6,700 Petawatt hours (PWh) of power from solar and wind energy, researchers claimed – more than 100 times the amount of energy consumed globally in 2019. Despite the potential for vast amounts of energy to be harvested, just 0.7 PWh of solar power and 1.4 PWh of wind energy was generated in 2019, according to the report. However, its authors were confident that continued falling costs were likely to drive exponential growth in the generation of solar and wind power. An annual growth rate of 15% would see solar and wind generating all of the world's electricity by the mid-2030s and providing all energy worldwide by 2050. The report noted that the cost of solar power had declined by an average of 18% per year since 2010, while wind power prices had fallen by an average of 9% every year in the same period."

"This supermoon has a twist – expect flooding, but a lunar cycle is masking effects of sea level rise"

"A "super full moon" is coming on April 27, 2021, and coastal cities like Miami know that means one thing: a heightened risk of tidal flooding. Exceptionally high tides are common when the moon is closest to the Earth, known as perigee, and when it's either full or new. In the case of what's informally known as a super full moon, it's both full and at perigee. But something else is going on with the way the moon orbits the Earth that people should be aware of. It's called the lunar nodal cycle, and it's presently hiding a looming risk that can't be ignored. Right now, we're in the phase of an 18.6-year lunar cycle that lessens the moon's influence on the oceans. The result can make it seem like the coastal flooding risk has leveled off, and that can make sea level rise less obvious."

"Will a New GFS Weather Model Upgrade Close the Gap with The European Model?"

"Are you with Team GFS or Team ECMWF, the "European Model"? I hate to pick sides, but as a meteorologist I defer to the weather model that, consistently, is most accurate. Of course I'm rooting for the "American Model", the GFS or Global Forecast System, to win. But here's the thing: if you're sanding a table or building a deck you want to use the best tools at your disposal, right? So it goes with weather forecasting. Meteorologists examine scores of models, looking for consistency, continuity, and trends – ultimately choosing a blend of model solutions that has the highest probability of coming true. Believe it or not, we want to get the forecast right! ECMWF vs. GFS Accuracy Since 2007. The data is the data. Graphic courtesy of and meteorologist Ryan Maue. Like most people I defer to what works, based on personal experience. And in recent years many meteorologists have reached the conclusion that I have over time: ECMWF, The European Model, is consistently more accurate. Not perfect, but stepping back and looking at the big picture…which prediction of future weather is better in most real-world scenarios? ECMWF wins most days. At the risk of oversimplification, there are many reasons why ECMWF is better. The European model is run by The European Centre for Medium-Range Weather Forecasts in Reading, England. Unlike NOAA, the U.S. National Oceanic and Atmospheric Administration, which runs dozens of models, ECMWF runs one global model at high resolution. All efforts and resources have been focused into perfecting this one weather simulation. There are other factors involved, including demonstrably better data assimilation (getting the most recent observations into the ECMWF model faster) and a steady pipeline of meteorological research (and better physics) being applied to improve the ECMWF model at a quicker pace. The result: ECMWF is arguably the best weather model on the planet."
