Share story

We saw plenty of rain Saturday afternoon and Saturday evening. Parts of Minnesota and western Wisconsin had wet snow or a mix of rain and snow Saturday night, which transitioned to mainly rain on Sunday.

Here are the precipitation totals (rain plus the water content of snow) for the 24-hour period ending at 7 a.m. Sunday:

The yellow-shaded area shows 1.5 to 2 inch totals.

St. Cloud set a precipitation record for March 28:

The weekend precipitation total at MSP airport was 1.29 inches.

Weekend snow totals were highest from central Minnesota into northeastern Minnesota and the far northwestern corner of Wisconsin:

Snow reports can be found here. You can hover over any snow report to get the exact snow total, plus the location and time of the measurement. You can also slide the map around to show snowfall reports from other parts of Minnesota and Wisconsin. If you go to the linked site on Monday, move the slider in the upper left corner to “48 hours” to get all the weekend reports.

A dry Monday, then rain returns midweek

Most of Minnesota and western Wisconsin will enjoy dry weather on Monday. The next meaningful precipitation arrives late Tuesday night or Wednesday. The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential precipitation pattern for Wednesday and Wednesday evening:

Parts of far northern Minnesota could see a combo of rain and snow on Wednesday.

Temps rebound

Monday highs reach the 50s across most of Minnesota and western Wisconsin:

Portions of northern Minnesota will top out in the 40s. I expect highs in the upper 50s in parts of the Twin Cities metro area. Our average March 30 high in the Twin Cities is 49 degrees.

Twin Cities metro area highs are projected to reach the mid 50s on Tuesday, followed by lower 50s Wednesday and Thursday and around 50 on Friday.

River levels are rising

The soaking weekend rains will contribute to rising river levels across southern Minnesota in the coming days. Flood warnings have been issued along some rivers in southern Minnesota, and the warnings are shaded green on this map:

Red River update

River level forecasts are updated on a regular basis. You can click on any location on the NWS Advanced Hydrologic Prediction Service (AHPS) site to get hydrographs of recent and forecast river levels. Some locations list levels in feet above sea level, others list levels in feet above a local reference point.

Here’s the Sunday evening hydrograph for the Red River at Fargo, North Dakota:

The hydrograph shows the Red River reaching major flood stage at Fargo on Wednesday. The 30- foot level forecast on Wednesday is well below the 40.82 ft. record flood level reached on March 28, 2009 (instantaneous measurement), according to the AHPS site.

It’s a good thing that the soaking rains this weekend missed northwestern Minnesota and eastern North Dakota!
