The March 11-12, 2023 "Super-Duper Clipper"
"The snowy winter of 2022-23 grinds on, with yet another large winter storm, this time with unlikely origins, producing widespread heavy snow and double-digit accumulations across northern Minnesota on March 11-12, 2023. A Super-DUPER Clipper The storm originated as a low-pressure area in the prairies of southwestern Canada on Friday, then moved east-southeastward across the northern Rockies, North Dakota, and northern Minnesota, before turning southeastward across Wisconsin on Sunday. This is a similar path to many "Clipper" systems, also called "Alberta Clippers," which are fast-moving systems common during the middle of winter, often producing 1-4 inches of light, powdery snow followed by strong winds and falling temperatures."
National Snowfall This Season
Snowfall has been quite impressive across parts of the nation this season, especially in the Western US, Midwest, the Great Lakes and the Northeast.
8th Snowiest Season at MSP
With more than 80" of snow, the MSP Airport is currently sitting at the 8th snowiest winter on record! We need less than 5" of additional snow to get into the top 5, but would need almost an additional 18" to get to the top spot.
More Snow Late Week
The weather models later this week are suggesting another wintry event later this week and into the weekend. It's still way too early to get specific, but areas of rain could turn to slushy snow late week with breezy winds.
Spring Flood Outlook
"Overall Outlook More Big Changes in the last two weeks... The early March updated outlook for spring flooding in the upper Mississippi, Minnesota, and Chippewa River basins has been upgraded to well above normal, particularly on the Mississippi from St. Paul downstream. The addition of more rain and snow over the past two weeks has raised the amount of water in the snowpack to very high levels for this time of year. Factors that could help alleviate at least some of the snowmelt threat are becoming less relevant the longer the snowpack holds on. And as always, the threat of seeing major flooding will still depend on what kind of rainfall/temperature patterns we get later in March and April. Due to the nature of this year's flood potential, we will issue an additional spring flood outlook on March 23rd, 2023."
Extended Temperature Outlook
The NBM extended temperature outlook for Minneapolis shows warmer midweek temps with readings up into the 40s. A larger storm system will move into the Midwest later this week with areas of rain and snow. Temperatures will fall into the 20s behind the system on Friday and Saturday, but should rebound fairly quickly as we head into next week.
