ACUS11 KWNS 122151 SWOMCD SPC MCD 122150 MIZ000-MNZ000-WIZ000-NDZ000-130145- Mesoscale Discussion 0235 NWS Storm Prediction Center Norman OK 0450 PM CDT Thu Mar 12 2026 Areas affected...northeastern North Dakota...northern Minnesota...northern Wisconsin Concerning...Heavy snow Valid 122150Z - 130145Z SUMMARY...Heavy snow will overspread portions of northeastern North Dakota, northern Minnesota, and northern Wisconsin tonight with snowfall rates likely range 1-2 inches per hour at times. DISCUSSION...A deepening surface low will shift southeastward from North Dakota into southern Minnesota this afternoon into tonight. Strong low-level warm air advection within the 900-700 mb layer aided by DCVA ahead of a mid-level shortwave trough and favorable jet streak dynamics are expected to combine to promote strong ascent within the dendritic growth zone. This will support heavy snowfall along and north of the track of the surface low, with rates 1-2 inches per hour at times. A strong surface pressure gradient on the northwestern periphery of the surface low will support the potential for sustained northerly winds at 30 mph, with the potential for wind gusts to 50+ mph. Given this, blowing snow is likely, with brief periods of blizzard conditions possible, especially across the northern Red River Valley late this evening. ..Thornton/Chalmers.. 03/12/2026 ...Please see www.spc.noaa.gov for graphic product...
