Administrators NorthGeorgiaWX Posted December 26, 2023 Administrators Share Posted December 26, 2023 MD 2347 CONCERNING BLIZZARD FOR SOUTHEAST NORTH DAKOTA...MUCH OF SOUTH DAKOTA...FAR WESTERN MINNESOTA...AND CENTRAL NEBRASKA Mesoscale Discussion 2347 NWS Storm Prediction Center Norman OK 0756 PM CST Mon Dec 25 2023 Areas affected...Southeast North Dakota...much of South Dakota...far western Minnesota...and central Nebraska Concerning...Blizzard Valid 260156Z - 260630Z SUMMARY...Heavy snow, freezing rain and blizzard conditions will continue into the overnight hours across portions of the central and northern Plains. DISCUSSION...A surface low has drifted northwest across Iowa through the day today and the 01Z surface analysis shows the surface low southeast of Sioux Falls, SD with a central pressure around 1001mb as it continues to occlude. Strong easterly warm air advection to the north of this surface low continues, and has somewhat overperformed from what most model guidance has shown. Therefore, most areas which were seeing freezing rain earlier have now warmed above freezing. The only exceptions is a confined area across eastern South Dakota and far southeast North Dakota where some freezing rain continues. Elsewhere, a broad region of light to moderate snow continues within a broad deformation zone from far western Minnesota to northern Kansas. Within this, some heavier snow is occurring. Especially across South Dakota and southern North Dakota. Winds are quite strong in most of the deformation zone (20 to 30 knot sustained winds with gusts to 30-45 knots). However, observations show greater visibility restriction farther west where temperatures are in the low 20s and snow ratios are likely higher. This entire region of wintry precipitation will drift slowly east into the overnight hours as the surface low continues to move northwest. ..Bentley.. 12/26/2023 ...Please see www.spc.noaa.gov for graphic product...
