Our wet April slop fest is underway.

Winter storm warnings continue for the northern half of Minnesota from the northwest to the northeast.

Heavy wet snow will continue to gradually pile up in the north through the overnight hour into Wednesday and even Thursday morning in the northeast. You can see on the map above parts of the North Shore could pick up 12 to 18 inches of snow by Thursday morning!

That kind of heavy wet spring snow can down trees and power lines. Check out the wording from the Duluth National Weather Service office on the winter storm warning for the North Shore:

Including the cities of Grand Marais, Two Harbors, and Silver Bay

209 PM CDT Tue Apr 1 2025

...WINTER STORM WARNING REMAINS IN EFFECT FROM 7 PM THIS EVENING TO 7 PM CDT WEDNESDAY...

* WHAT...Heavy lake effect snow expected. Total snow accumulations between 9 and 13 inches except between 12 and 16 inches for the higher terrain of the North Shore and ice accumulations around a light glaze. Winds gusting as high as 45 mph.

* WHERE...Southern Cook and Southern Lake Counties. This includes the Tribal Lands of the Grand Portage Reservation.

* WHEN...From 7 PM this evening to 7 PM CDT Wednesday.

* IMPACTS...Travel could be very difficult to impossible. Widespread blowing snow could significantly reduce visibility leading to near whiteout conditions. The hazardous conditions could impact the Wednesday morning and evening commutes. Gusty winds could bring down tree branches.

The National Oceanic and Atmospheric Administration’s Tuesday afternoon 18Z High-Resolution Rapid Refresh model run shows the evening snow burst in the Twin Cities moving north with snow continuing through Wednesday.

The forecast model loop below runs between 7 p.m. Tuesday and 10 p.m. Wednesday.

The Twin Cities will likely pick up a couple of slushy inches mainly on grassy areas Tuesday evening. Heavier snow will favor the northern Twin Cities.

Rain and a few thunderstorms will bubble across southern Minnesota Wednesday.

Wet spring turn

Our meteorological spring has taken one of the wettest turns on record for parts of southern Minnesota. The wet last weekend of the month produced a few records.

Climatologist Mark Seeley, my MPR News colleague, passed along these eye-opening precipitation numbers Tuesday:

South-central Minnesota counties reported their wettest March in history with an average of 3.85 inches, and southeastern Minnesota reported their 5th wettest March with an average of 3.49 inches. Some individual climate stations that reported their wettest March in history included:

Owatonna 5.36 inches

Winnebago 4.96 inches

Hastings Dam 4.32 inches

Wells 4.11 inches

Sunnier days ahead

Our lollygagging storm will finally pull away Thursday. Look for much more sunshine through Saturday and milder temperatures. Highs in the 50s will be common in the south.

There are signs this may be the last big spring snow event for most of Minnesota. Some models hint at highs in the 70s the weekend of April 12-13.

Stay tuned.
