Sunday marks the 50th anniversary of "Black Sunday", a day which brought F4 tornadoes across southern Minnesota and 20 foot waves in Duluth. Four people lost their lives due to the waves in Duluth, and 13 deaths were linked to tornadoes across Minnesota and Iowa. The Weather Service Office in Duluth gives some perspective about the day and the impacts in Duluth - I'll quote some of them below, but you can read more by clicking here.

This storm brought 45 mph gusty winds coupled with a lake temperature of 36 °F to the shoreline. The Halverson brothers, Eric, Nathan, and Arthur, like many others went down to the pier to get a view of the waves crashing onto the walkways. Venturing along the north pier, a 20 foot wave crashed over the wall, sweeping the brothers off the pier. Coast Guardsmen were called into a rescue attempt to save the brothers. In their attempt, Boatswain Mate First Class Edgar A. Culbertson was swept off his feet by a strong wave into the canal. The Halverson brothers and Culbertson lost their lives."
Historical May Twin Cities Snow
A Soaking Cold Rain Expected To End April
By D.J. Kayser, filling in for Paul Douglas
Minnesota weather always seems to have something interesting hiding up its sleeve. One minute it’s warm and sunny, the next brings you accumulating snow.
Even with the recent round of cool weather, the odds are still good that April will be the twentieth consecutive month with above average temperatures in the Twin Cities. This is a streak that stretches back to September of 2015.
And yet, here we are talking about the potential of snow in early May! A storm system will bring rain to a good portion of southern Minnesota Sunday, with amounts potentially topping an inch across the metro. Enough cold air will wrap in Sunday Night into Monday to bring at least a plowable snow from Marshall to Brainerd and Hibbing. We might see a few snowflakes early and late Monday in the metro, but only minor slushy accumulations at most are expected.
The good news? After this system, we begin a warming trend, with highs approaching 70 once again by next weekend. Is this upcoming storm winter's final punch? We can only hope so.

Offshore Arctic Drilling
President Trump signed an executive order Friday to try and restore offshore drilling in the Arctic. What can Trump actually accomplish here? More from InsideClimate News: "The area in question includes the entirety of the Chukchi Sea and most of the Beaufort Sea off Alaska, as well as a stretch of the Atlantic Ocean from Massachusetts to Virginia. Obama's executive order relied on his powers under the Outer Continental Shelf Lands Act of 1953 (OCSLA), which allows a president to withdraw certain areas from drilling."
EPA Webpages Disappear
Friday night the EPA wiped climate data off their website after announcing that there would be changes made. The Washington Post has more: "One of the websites that appeared to be gone had been cited to challenge statements made by the EPA’s new administrator, Scott Pruitt. Another provided detailed information on the previous administration’s Clean Power Plan, including fact sheets about greenhouse gas emissions on the state and local levels and how different demographic groups were affected by such emissions."
