Weather Models Are Part Of The Equation

Our ration of rain is over with clearing today and a bright-blue sky returning tomorrow. 50s linger into Thursday, close to average for late October. Mild Pacific winds blow into early November, with 60s this weekend - spilling into next week. Confidence levels are high the models are correct. Check the blog for more details. -Todd Nelson

Muddy Rain?

It rained across parts of the region Sunday night into early Monday with many reports of muddy cars. What gives? Thanks to strong southerly winds, dust was carried from the plains and was deposited on outdoor surfaces close to home. Here's more from the MPCA:

Precipitation Departure From Average This October

It's been a dry October with many locations nearly 1" to 2" below average for the month of October. The Twin Cities is closer to 2" below average, which is good enough for the 9th driest October on record so far.

Precipitation Departure From Average This Fall

If you look at the precipitation deficit for the season (since September 1st) the deficit is even greater. Many locations are well below average with the Twin Cities more than 4.50" below average, which is the driest September 1st through October 23rd on record.

Precipitation Departure From Average Since Jan. 1st

The Twin Cities is more than 9.60" below average for the year, which is good enough for the 17th driest start to any year on record. Meanwhile, International Fall, MN is more than 9.60" above average, which is good enough for the 2nd wettest start to any year on record.

Drought Update

It has been a dry year for many across central and southern MN. Extreme drought continues across parts of the Twin Cities to the Minnesota River Valley where rainfall deficits have been the greatest. It would be nice to get a good soaking prior to heading into winter, but it doesn't appear that anything substantial is on the way anytime soon.

Fall Color Update

Here's the fall color update for Minnesota & Wisconsin. Fall colors are generally past peak in many spots across the state. There is still some peak color in the southeastern part of the state, but with strong winds during the day Sunday, we'll lose a lot of leaves.

Another Mostly Dry Week Ahead

The weather outlook through the week ahead looks dry once again with much of the precipitation potential staying well to the southeast and east through midweek. There could be a few light rain showers close to home on Thursday, but it won't amount to much if any at all.

8 to 14 Day Temperature Outlook

8 to 14 Day Precipitation Outlook

According to NOAA's Climate Prediction Center, the 8 to 14 Day precipitation outlook shows more active weather setting up across the Northwest and possibly across the northern tier of the nation. We'll see what happens, but it certain has been dry across the Upper Midwest and we could use the moisture.

Weather Models Are Part Of The Equation
By Paul Douglas

Will we all be replaced by super-smart robots that don't ask for raises or PTO? I hope not. Recently a friend asked "Paul, do meteorologists actually work? Don't you just go with the weather models?" Ouch.

Models are getting better, but they're a long way from perfect. Based on personal experience (being wrong a lot) we have a sense of which model to believe - when. Data shows the best weather forecasts are a mix of man and machine. I'd say 60-70% of our day comes down to digesting (and correcting) weather models. Knowing when to ignore them is key.

In the future machine-learning and artificial intelligence may redefine best practices and generating the most accurate forecasts. The only predictable thing is change.

Our ration of rain is over with clearing today and a bright-blue sky returning tomorrow. 50s linger into Thursday, close to average for late October.

Mild Pacific winds blow into early November, with 60s this weekend - spilling into next week. Confidence levels are high the models are correct.

Climate Stories

(NOAA/The Minnesota Star Tribune)

"Drought to tighten its grip on U.S. this winter, forecasts show"

"The third straight La Niña winter in the U.S. is likely to cause drought to expand and deepen from California to the Plains, branching out across the Southeast, NOAA said Thursday. How it works: Currently, water levels along certain stretches of the Mississippi River are so low that centuries-old shipwrecks are being revealed, and modern-day barge traffic is imperiled. Farmers in multiple states are facing the prospect of a challenging winter wheat season. After a dry winter, if spring rains falter in Texas, there would be a growing possibility of summer water supply constraints, experts warn. The big picture: The new seasonal drought outlook through January depicts a weather pattern that is heavily influenced by a rare, three-winter "triple dip" La Niña in the tropical Pacific Ocean. La Niña conditions feature cooler-than-average ocean temperatures in the equatorial tropical Pacific. They can influence weather patterns worldwide."

"California's climate goals are going up in smoke: study"

"A new study puts some hard numbers on the climate impacts of California's worsening wildfires, finding that the state's 2020 blazes overwhelmed its recent emissions cuts. Driving the news: The study, published in Environmental Pollution, is among the first to quantify the carbon emissions from California's fires and the damage they are causing. Zoom in: The 2020 fire season was record-setting, with 4.3 million acres burned. Five of the top 20 largest fires in state history occurred that year, including one so-called "gigafire" that burned more than 1 million acres. Scientists used independent methods to estimate the wildfire-related carbon dioxide-equivalent emissions and found they were about double the state's emissions reductions from 2003-2019. With fire-related emissions included, there was a 30% state emissions jump between 2019 and 2020. The research also estimates the cost associated with the added CO2 emissions, calculating about $7 billion in damage from added warming."

"Why You Shouldn't Cancel Your Upcoming Trip to Puerto Rico"

"Five years ago, Puerto Rico gained international acclaim when the hit song "Despacito" reached the top of the Billboard charts. For the first time, it seemed like all eyes were on this small island in the Caribbean, approximately 100 miles long by 35 miles wide. Suddenly, there was a surge in visitors like never before. Even neighborhoods like La Perla, previously considered off-limits to tourists, were receiving renewed interest. Then Hurricanes Irma and Maria hit, and the island was devastated. Lives were lost, relief funds were mismanaged, and hundreds of thousands of Puerto Ricans emigrated to the mainland United States."
