A frontal boundary moved through last, which helped to push the hot and humid weather farther south. In its wake much cooler and less humid air will settle in for the rest of the week. Dewpoints were in the upper 60s to near 70F on Tuesday and will drop into the upper 30s and lower 40s on Wednesday. Note that for every 20F drop in dewpoint temps, there is half as much as water in the atmosphere, so it'll be a significant difference.

Here's the max dewpoint for Minneapolis over the next few days. Keep in mind that the highest dewpoint readings on Wednesday will be just after Midnight and will fall into the 40s through the end of the week.

It's that time of the year again for fall colors and the MN DNR has their fall color finder up and running. Much of the state is still color free, but there are a few colors popping up here and there.

The MN DNR has put together a nice graphic that shows typical dates for peak fall color. The northern par of the state starts to peak during the 2nd half of September into early October. Meanwhile, folks in the central part of the state and into the metro typically don't see peak color until the end of September into the middle part of October. It won't be long now - enjoy!

Here's the 30 year average for the first frost in Minneapolis, which lands on October 13th. Last year (2021) the first frost was on October 23rd.

Here's a view of Hurricane Fiona from PM Tuesday, which was a major category 3 storm with 115mph winds. Fiona caused catastrophic damage and flooding in Puerto Rico over the weekend and earlier this week. Unfortunately, Fiona is expected to strengthen into a category 4 storm with 140mph winds through the end of the week.

Tropical Alerts continue from the Turks and Caicos to Bermuda and Hurricane Fiona continues to track north.

Here's the track of Hurricane Fiona as it drifts north through the rest of the week. Note that Fiona could strengthen to a category 4 as it approaches Bermuda on Friday. Fiona could still be a hurricane as it approaches Nova Scotia this weekend with an intense storm still in place over eastern Canada into early next week.

After a lousy April we did, in fact, salvage areal summer, with above-average temperatures and a generous supply of sunshine. All those blue-sky days accelerated drought over southern counties, but with any luck a parade of October storms will replenish some of that water. MSP went 116 consecutive days with daytime highs of 70+. That's a record.

One thing I've learned over 45 years of tracking hurricanes most of the misery, dislocation and death comes days and weeks AFTER a storm hits. "Fiona" has left millions without power and water in Puerto Rico. This, from a Category 1 storm.

European model guidance predicts a major hurricane in the Gulf of Mexico late next week. Stay tuned.

The weather outlook on Wednesday shows well above average temperatures across the Central and Eastern US, where record highs will be possible. There could be strong to severe storms in the Eastern Great Lakes and also through the Intermountain-West. Meanwhile, cooler temps will settle in across the Midwest.

Showers and storms will move through the Eastern Great Lakes and into the Northeast with lingering showers and storms through the Intermountain-West.

Here's the weather outlook through Thursday, which shows storms pushing through the Northeast, some of which could be strong to severe. There will also be another round of heavier t-storms across the Intermountain-West.

"The science is unequivocal: we are going in the wrong direction" when it comes to addressing climate change, a new report from the World Meteorological Organization says. This year's planet-heating pollution has risen above pre-pandemic levels. All over the world, people are already facing dire consequences from the 1.2 degrees of global warming human activity has caused since the industrial revolution. "Heatwaves in Europe. Colossal floods in Pakistan. Prolonged and severe droughts in China, the Horn of Africa and the United States. They are the price of humanity's fossil fuel addiction," UN Secretary-General António Guterres said in a press release and accompanying video today."

"I was eating breakfast on a Monday morning at Sears Fine Food in downtown San Francisco, casually watching the local five-day weather forecast on a television screen behind the counter. A little symbol along the bottom showed a happy-looking sun for the rest of the day. Wednesday had a friendly-looking cloud and a few raindrops, and Thursday had a dark, threatening cloud with heavier drops. I knew Thursday's conditions would be much rougher than the symbol conveyed. I had been studying detailed satellite data and weather models, and they indicated that a major atmospheric river (AR) was likely to hit the city. The symbol was completely inadequate for communicating the threat of the approaching storm."

A swarm of giant drones navigates a scorched moonscape, tracing the rugged topography. The scene has a desolate, sci-fi vibe — but its reality is rooted in the terra firma. The devices belong to DroneSeed, a Seattle startup deploying technology to help restore some of the millions of acres of forests that have burned in wildfires across the U.S. and beyond. The conflagrations include fires so intense that they don't leave any live trees to provide new seeds or seeds in the soil, and so massive that they create barren islands far from seed sources. Left alone, the burns could sit as treeless grass or shrubland for years. As another devastating wildfire season (hopefully) winds down, the company will be dispersing seeds this fall and spring over hundreds of acres in Washington, Oregon, California and Montana.
