Heavy Rain And Flooding Over The Past Few Days

Highway 23 at the Nemadji River (south of Highway 210) was washed out Saturday Night due to heavy rain. As you can see from the above image, courtesy of the Minnesota Department of Transportation on Facebook, the road is completely impassable. This area of the state was under a Flash Flood Emergency Saturday night due to the very heavy rain that fell across the region leading to flash flooding.

The Nemadji River did set a new record height on Sunday below Superior, WI.

Meanwhile, Minnesota wasn't the only state that observed washed out roads due to heavy rain Saturday Night. This was U.S. 2 in Bayfield County, WI, at North Fish Creek, now impassable due to heavy rain Saturday Night. Photo: @WisDOTnorthcent on Twitter.

The heaviest rain fell from parts of central Minnesota into northwestern Wisconsin (and eventually the U.P. of Michigan) over the 24 hour period that ended at Noon on Sunday, with numerous reports of at least 3" of rain. The highest totals were across parts of northwestern Wisconsin, where stations around Drummond reported 9-12" of rain, and the RAWS site at Barnes, WI, recorded 7.74" of rain.

This is the rain forecast from Sunday to Tuesday evening across the region. We see that rainfall totals of at least an inch to two inches can be expected from southwestern Minnesota into northwestern Wisconsin. Especially across areas of northern/central Minnesota that have received heavy rainfall the past few days we will have to watch the potential for flooding.

Due to the potential of heavy rain, Flash Flood Watches have been issued Sunday Night into Monday across parts of eastern Minnesota into northern and western Wisconsin.


Dewpoints In The Upper 70s Saturday Evening

It got downright oppressive in the Twin Cities Saturday evening, as the dewpoint climbed to a very tropical and sticky 78F for the 7 PM and 8 PM observations. With the 7 PM temperature of 87F, it felt more like 100F out!

That dewpoint of 78F is the highest dewpoint the Twin Cities has observed since the summer of 2011 according to the Minnesota State Climatology Office. On July 19th that year the Twin Cities saw a dewpoint of 82F, which is the highest on record for the observation site.


Cooler Highs Return - Lingering Storm Potential
By D.J. Kayser, filling in for Paul Douglas

Did you enjoy the sweltering weather across southern Minnesota this past weekend? I, for one, did not; during this type of weather you can typically find me in front of the air conditioner, patiently waiting for the next cold front to blow on through the region. Yes, even the meteorologist gets to complain about the weather every once in a while.

The dewpoint - a measure of the amount of moisture in the air - hit an oppressive 78F at the MSP airport Saturday evening. That’s the highest we’ve seen since 2011, which was the year we saw a record 82F dewpoint on July 19th. According to the Minnesota State Climatology Office, the Twin Cities have only recorded 28 hours since 1945 with a dewpoint of 80F or higher.

Cooler temperatures and lower dewpoints return as we begin this new work week, however, a few showers and storms may linger across southern Minnesota today. We’ll see drier weather for the middle of the week in the Twin Cities before more storm chances arrive by next weekend.

Minnesota Weather Outlook

We'll still have lingering showers and storms across southern Minnesota as we go throughout your Monday, but for the most part the front which has been lingering across the state throughout the weekend will push south. If you want sunnier skies, you'll have to head toward northern Minnesota. Most areas will see 70s for highs.

Highs across southern Minnesota Monday will be a few degrees below average for mid-June, with highs in northern Minnesota a few degrees above average.

Behind the front dewpoints will be lower than what we saw this weekend across the state, even if we are stilll holding onto the muggy 60s across parts of southern Minnesota.

Temperatures will be cooler as we head through this work week than what we saw this weekend, only hanging in the upper 70s to low/mid 80s here in the Twin Cities, which will be right around average for this time of year.

We do watch more precipitation chances in the forecast, particularly to begin and end the week. We could see an additional half an inch to an inch of rain from Monday through next weekend.


National Weather Forecast

A slow moving cold front will continue to move south and east from the Central Plains to the Great Lakes and the Northeast, bringing the threat of showers and storms along with it. Showers and storms will also be possible across parts of the Northern Rockies. Across the Texas coast, tropical moisture and low pressure will help produce heavy rainfall across the region. Afternoon storms will be possible across the Southeast due to the heating of the day.

The heat that the upper Midwest saw this weekend will continue to work its way east into the beginning of the week. Record highs could be set in parts of the Northeast Monday including areas like Washington D.C., Allentown (PA), and Manchester (NH).

We will be tracking two areas for very heavy rain across parts of the nation through Friday morning. One will be across parts of the Central Plains, where 2-4" of rain could fall this week due to a slow moving front and upper level low. Heavy rain of at least 2-5", with isolated 10-15" amounts, will fall across parts of Texas due to tropical moisture being pumped in from the Gulf of Mexico.

Areas like Houston, Corpus Christi, and South Padre could see at least 3-6" of rain through the first couple days of the work week.

Meanwhile some of the heaviest rain looks to fall across parts of Nebraska and Kansas Tuesday and Tuesday Night, and there already a "moderate" risk of heavy rain that could lead to flooding.


Pollinators, but No Pollen: Spring Heat Left Europe's Plants, Insects Out of Sync

More from InsideClimate News: "In a patch of scruffy prairie near Vienna, marbled white butterflies hover near clusters of unopened globe thistles. They uncurl their long proboscises to probe the spiky buds—without success. It'll be a couple more weeks before the flowers open, but some of the butterflies may not survive that long if they don't find something else to eat. Two months of unusually high spring temperatures in Europe have thrown the ecosystem in this urban wilderness meadow out of whack, says butterfly expert Marion Jaros. The warm temperatures accelerated the hatch of many butterflies and other pollinating species, but the flowers they depend on for nectar are not responding in sync. "Here, too, you can see climate change," Jaros says, as a hot, dry wind rustles the tall grass, dried to golden straw a month sooner than usual. Important pollinator species are being affected across Europe, she adds."

As Nuclear Struggles, A New Generation Of Engineers Is Motivated By Climate Change

More from NPR: "The number of people graduating with nuclear engineering degrees has more than tripled since a low point in 2001, and many are passionate about their motivation. "I'm here because I think I can save the world with nuclear power," Leslie Dewan told the crowd at a 2014 event as she pitched her company's design for a new kind of reactor. Dewan says climate change, and the fact that nuclear plants emit no greenhouse gasses, is the big reason she became a nuclear engineer. And she's not alone. "The reason that almost all of our students come into this field is climate change," says Dennis Whyte, head of the Department of Nuclear Science and Engineering at the Massachusetts Institute of Technology."
