Past Memorial Day Monday Weather - And The Forecast For 2020
Memorial Day has been an official federal holiday since 1971, and even with it being at the end of May temperatures can vary a lot. Since 1971, we've seen a high of 100F (back in 2018), a low of 39 (back in 1993) and up to 1.83" of rain (2018) at MSP airport. The Minnesota State Climatology Office/MN DNR notes that the day remains dry 60-70% of the time. Click here to read more, including climatological stats for the full Memorial Day weekend.
Unfortunately, this Memorial Day won't be one of those dry ones as scattered showers and thunderstorms will be in the forecast. It doesn't look like an all-day wash out, though.
So while we will watching those shower and thunderstorm chances Monday, highs will climb into the 70s across many areas of the state with a few 80s in southern Minnesota, including the Twin Cities. Along the North Shore, temperatures will be stuck in the 60s
Across most of the state, these highs will be several degrees above average - including almost 10F degrees above the norm for the day in the Twin Cities, Rochester, and Grand Marais. The average high in the Twin Cities for May 25th is 72F.
A few of the storms across southeastern Minnesota into Wisconsin could be on the strong side Monday with a Marginal Risk of severe weather in place. Large hail would be the main threat.
May Rain (Through Saturday)
As mentioned in the header, these graphics only show rain through Saturday, so they don't reflect the rain that moved across southern Minnesota Sunday morning. Once you go north of the Twin Cities, it has been a fairly dry month in central and northern Minnesota so far. All NWS climate sites norare running more than an inch below average - and are approaching 2" below in some spots. In St. Cloud, it is the 19th driest start to the month and would be the 5th driest May if no additional rain after Saturday fell. In Duluth, it is the 4th driest start to May and would be the 2nd driest overall May if no additional rain fell.
Hugo 2008 EF-3 Tornado
Monday marks the 12th anniversary of the EF-3 tornado that hit the Lino Lakes and Hugo areas which sadly resulted in one fatality. It was on the ground for 6 miles and was an eighth of a mile wide at times. Three other tornadoes touched down in Minnesota that day, along with one in western Wisconsin. CLICK HERE for a summary of the severe weather that day (which also included hail larger than golf ball sized) from the National Weather Service Twin Cities office.
Holiday Puddle Potential. 90s by June?
By Paul Douglas
"Patriotism is supporting your country all the time, and your government when it deserves it" said Mark Twain. Today we honor the souls who sacrificed everything to keep us free. One lesson of history: take nothing for granted, because it can be taken from you - by force.
I am in awe of those who serve, including my Navy son, Brett, who flew helicopters in the South China Sea and Persian Gulf. He came back with new eyes, new appreciation for America, warts and all.
Today we also celebrate a long, rich tradition of Memorial Day downpours. No all-day rain expected, but an unstable, irritable atmosphere will ignite more showers and T-storms; some of the rain will be locally heavy. No need to water the yard anytime soon.
We clear out late Tuesday with 80-degree sunshine Wednesday, followed by a slight late week cooling trend late week.
If we keep promising a hot front long enough, the forecast will eventually come true. NOAA's GFS model predicts a week of 90s the first week of June. Bring it on.

Twin Cities And Minnesota Weather Outlook
We'll keep an eye on those scattered shower and thunderstorm chances as we head through Memorial Day in the Twin Cities. Temperatures will start the morning off in the mid to upper 60s with highs topping off (for the first time this year (hopefully)) in the low 80s.
National Weather Forecast
For Memorial Day Monday, showers and thunderstorms will be possible across most of the central United States as well as portions of the eastern U.S., particularly in the Southeast. A few snow showers will be possible in the central Rockies. Rain will be possible in the Northwest. A few record highs will be possible in Calfornia and the Ohio Valley.
A couple of areas of heavy rain are expected through 7 PM Tuesday. One is across southern Florida, where rainfall amounts of 3"+ are possible and some localized areas could see up to 6". Heavy rain is also expected across the central United States as 2"+ are possible across the central and southern Plains with some of the heaviest expected in southern Texas. Several inches of snow will be possible in the northern and central Rockies.
Heavy Southern Florida Rain
Heavy rain will impact southern Florida through the Memorial Day holiday, with the potential of up to 6" of rain in some locations. Due to this, a Flood Watch has been issued, including Miami.
Heat Builds In The Southwest
Meanwhile, as we head into the week heat will be building across the Southwestern United States. Already Excessive Heat Warnings are in place for Las Vegas and Phoenix for Wednesday through Friday. Highs in Phoenix are expected to top 110F Thursday and Friday. Here's a look at highs Monday through Friday across the Southwest:
Bad weather might delay SpaceX's historic launch of NASA astronauts to May 30
More from Business Insider: "Clouds and rain could thwart the historic first launch of NASA astronauts in a SpaceX spacecraft on Wednesday. The mission, called Demo-2, will fly seasoned NASA astronauts Bob Behnken and Doug Hurley in the company's Crew Dragon spaceship. The flight's success would effectively resurrect human spaceflight from America after nearly a decade of dormancy. But a forecast of cloudiness, rain, and isolated thunderstorms leaves only a 40% chance that the spacecraft will be able to safely launch on Wednesday, according to the space wing of the US Air Force. If the rain makes launch untenable, SpaceX and NASA will fall to their backup date: Saturday, May 30."
100-Year Drought Hits Poor EU Region Already Reeling from Virus
More from Bloomberg: "First the virus lockdown shuttered the two dairies where farmer Gavrila Tuchilus sells the milk from his 1,500 cows. Then his fields dried up, forcing him to abandon his barley crop for the first time in 39 years. “A double war is taking place,” said Tuchilus, from Matca, a village in southeast Romania. “It’s a war against the invisible Covid-19 and a war with the drought.” The dry spell that’s scorching parts of the European Union’s eastern wing is devastating harvests and exacerbating what’s expected to be the region’s deepest economic downturn since at least the fall of communism."
Weather Disasters Are Mounting Amid The Pandemic. Michigan Floods Are Just The Latest.
More from the Huffington Post: "Rivers swollen from days of record-breaking rain topped two dams in Michigan’s Midland County this week, flooding neighborhoods with enough brown, muddy water to fill an Olympic-size swimming pool every two seconds. The flooding sent 10,000 residents who had sheltered in place from the coronavirus pandemic scrambling for higher ground. Parts of the county 140 miles northwest of Detroit are facing 9 feet of flooding as nearly 5 inches of rain fell over 36 hours, the kind of deluge that takes place only once every 25 to 50 years, meteorologist Paul Gross said. The National Weather Service called the disaster “extremely dangerous” and urged drivers who encounter inundated roads to “turn around, don’t drown.”"
