Heavy Southern Minnesota Rain

After a wet May across southern Minnesota, including the 20th wettest May on record for Rochester, some areas have once again been soaked by heavy rain the past couple days. Through 4 PM Saturday (at airport observation sites), New Ulm had picked up 4.67" of rain, with 3.00" falling nearby in St. James and 2.23" in Mankato. Meanwhile, a RAWS site south of Carver had picked up 4.44" of rain over the 48 hour period.

This heavy rain is leading to rising rivers across the region as well. The Cottonwood River at New Ulm is currently in action stage, but is expected to reach minor flood stage Sunday morning, cresting at around 11.6 ft into early next week.

Drier Day Sunday - Strong Storms Possible Monday
By D.J. Kayser, filling in for Paul Douglas

June can be quite a stormy month across southern Minnesota. It is typically the second wettest month of the year with an average of 4.25” of rain falling at the MSP airport. However, we have seen up to 11.67” fall during the month back in 1874, which is the fourth all-time wettest month on record.

This month has its fair share of severe weather as well. In fact, next weekend marks the anniversary of both the largest and second largest tornado outbreaks in Minnesota history. The largest occurred on June 17, 2010, with a total of 48 tornadoes across the state. The second largest outbreak was back on June 16, 1992, with 27 tornadoes including an F5 tornado that struck Chandler.

While we saw scattered storms Saturday, today will be better with dry but fairly cloudy conditions. Monday will be hot and muggy ahead of a cold front which will spark off strong storms across central and southern Minnesota late in the day. Comfortable weather returns for the middle of the week before more unsettled weather is possible heading toward Father’s Day.

Minnesota Weather Outlook

While there may be a lingering storm during the morning hours across southern Minnesota, Sunday is likely to features a lot of clouds across most of the state. The best chance of seeing mainly sunny skies is across northern Minnesota in the afternoon, but we should see a few peeks of sun across southern Minnesota as well. Highs will climb into the 70s and 80s across most of the state, with cooler temperatures along the North Shore.

If you're enjoying a day along the North Shore, temperatures will mainly be in the 60s due to a northeasterly breeze with a mix of clouds and sun.

These highs will be several degrees above average across most of the state Sunday, with the largest departure from average numbers expected across northwestern Minnesota.

There is a Marginal Risk of severe weather across parts of southwestern Minnesota on Sunday, mainly for the overnight time frame. Large hail and damaging winds appear to be the greatest threat.

More strong storms are possible across southern Minnesota Monday as a cold front moves across the state. While storms will likely be ongoing in the morning, storms that redevelop in the aftenoon that would be capable of large hail and damaging winds.

There is also a Slight Risk of excessive rainfall on Monday across parts of southern and central Minnesota. What this means is that there is the potential of enough rainfall that would cause flash flooding.

Highs will remain around 80 for the most part this upcoming week, with Monday being the exception as highs will have the potential to climb into the mid/upper 80s. There is the potential of slightly warmer weather in the models as we head toward Father's Day as well.

We will have the potential of some heavy rain on Monday as the cold front moves through the region. After that, while there may be a few isolated shower/storm chances (mainly at night) through the middle of the week the next best chance of seeing heavy rain will come as we head toward the Father's Day weekend.

National Weather Forecast

Sunday will feature the same quasi-stationary boundary we've been tracking still sitting from the upper Midwest into the Mid-Atlantic, with showers and storms possible. A stronger cold front moving east will bring showers and storms to the Northern Plains, and even some higher elevations snow behind it in the Cascades and Northern Rockies. The heating of the day will allow showers and storms to pop across parts of the Deep South and Southeast. 90s will be possible Sunday as far north as the North Dakota/Canadian border, with 100s possible as far north as parts of Nebraska.

The heaviest rain through next Thursday morning is expected from the upper Midwest to the Mid-Atlantic, where a quasi-stationary front will allow waves of rain and storms to ride along it. Some areas - especially across southern Minnesota and south of Washington D.C. - could see over 3-4" of rain.
 
 
After reaching Category 4 strength on Friday, Aletta is quickly weakening in the Eastern Pacific. Here was a satellite loop of the storm on Saturday. As of late Saturday evening, Aletta was barely hanging on to hurricane strength.
 
 
Aletta will continue to move off in a westerly direction over the next several days with the weakening trend continuing.
 
 
We've been watching another area of interest behind Aletta, and as of late Saturday afternoon it became Tropical Depression Three-E. This system is expected to become a tropical storm Sunday, getting the name of "Bud," then quickly strengthening into a hurricane by Monday morning.

5th U.S. Lightning Death Of 2018: Man Dies After Being Injured by Lightning Friday in Maumelle

More from Fox 16: "A man has died after being injured in a lightning strike Friday afternoon.  Family confirms 27-year-old Tyler Grisham died around 5:00 a.m. Saturday morning.  He had been hospitalized after the lightning strike in Maumelle around 2:30 p.m. Friday.  Grisham was working in a yard on Coronado Cove when the lightning struck."

Large Hail Pummeled The Dallas Metroplex Earlier This Week

More from Praedictix: "Storms impacted the Dallas metro Tuesday Night bringing large hail up to the size of baseballs and teacups. Radar shows the strong storm responsible for the large hail over parts of the Dallas Metroplex around 1:40 AM June 6, 2018. Due to this hail, there were numerous reports of damage to vehicles and buildings, and according to ABC-13 in Dallas, “One person says every single car in an apartment complex in Carrollton had its windows blown out.”"

Salem drinking water crisis: Oregon’s dry spring may have fueled toxic algae spread

More from the Stateman Journal: "One of the hottest and driest months of May on record may have contributed to the growth and spread of the toxic algae bloom wreaking havoc in Salem’s drinking water.  The algae bloom was originally spotted in Detroit Lake on May 8 and reached highly toxic levels around May 21, according to officials.   The record heat and dry conditions apparently kept the bloom strong, allowing the toxins to spread from the reservoir, into the North Santiam River and finally into Salem's drinking water for the first time at dangerous levels.   Salem issued its second do-not-drink alert Wednesday for vulnerable populations  following the discovery, for the second week in a row, of high levels of cyanotoxins in the drinking water. "

In desert trials, next-generation water harvester delivers fresh water from air

More from Science Daily: "Last October, a University of California, Berkeley, team headed down to the Arizona desert, plopped their newest prototype water harvester into the backyard of a tract home and started sucking water out of the air without any power other than sunlight.  The successful field test of their larger, next-generation harvester proved what the team had predicted earlier in 2017: that the water harvester can extract drinkable water every day/night cycle at very low humidity and at low cost, making it ideal for people living in arid, water-starved areas of the world.  "There is nothing like this," said Omar Yaghi, who invented the technology underlying the harvester. "It operates at ambient temperature with ambient sunlight, and with no additional energy input you can collect water in the desert. This laboratory-to-desert journey allowed us to really turn water harvesting from an interesting phenomenon into a science.""

China’s Dramatic Solar Shift Could Take Sting Out of Trump's Panel Tariffs

More from InsideClimate News: "The American solar market may be about to get boost from an unexpected source: Energy analysts say the Chinese government's decision to dramatically cut its solar power subsidies will create a glut of solar panels and send their prices tumbling worldwide.  It comes at a crucial time for American solar installers. Falling prices could take the sting out of President Trump's solar panel tariffs, which have raised costs in the United States and led to billions of dollars in cancelled and frozen U.S. investments."

Humans put conservation reserves at risk

More from Climate News Network: "Many of the world’s conservation reserves, intended to safeguard species at risk of survival, are increasingly unable to provide effective refuge.  At least one third of all the forests, grasslands, wetlands and mangroves notionally protected by laws to safeguard the wild things that evolved with them are under intense human pressure, according to the first detailed study for 25 years.  Major road systems criss-cross African wildlife reserves, cities have grown up in national park areas, and farmland and buildings blight landscapes supposedly reserved for endemic species at hazard from extinction. Altogether 6 million square kilometres (2.3m square miles) of protected land, researchers say, are “under intense human pressure.”"
