Administrators NorthGeorgiaWX Posted March 3 Administrators Share Posted March 3 MD 0185 CONCERNING HEAVY SNOW FOR NORTH DAKOTA Mesoscale Discussion 0185 NWS Storm Prediction Center Norman OK 1101 AM CST Sun Mar 03 2024 Areas affected...North Dakota Concerning...Heavy snow Valid 031701Z - 032100Z SUMMARY...Heavy snowfall rates between 1-2 inches/hour should continue through late morning/mid afternoon across portions of central to northern North Dakota. DISCUSSION...Over the past hour, surface observations have reported visibility reductions down to 1/2 to at times 1/4 mile with corroborating observations from regional web cams. These visibility reductions are most likely attributable to heavy snowfall rates rather than blowing snow given the weak winds (generally less than 10 knots) and warm temperatures in the upper 20s to low 30s. Ascent through a deep layer is evident over central/northern ND owing to upper-level diffluence ahead of an upper trough axis overlaid with a plume of isentropic ascent within the 850-700 mb layer. This combination of synoptic and more focused mesoscale ascent should continue to promote widespread moderate snowfall across central/northern ND over the next several hours with heavier rates up to 1-2 in/hour within more organized snow bands. Lightning flashes and cooling cloud-top temperatures have been observed over the past hour within this zone of strong ascent, indicating that weak convection may locally augment snowfall rates as well. ..Moore.. 03/03/2024 ...Please see www.spc.noaa.gov for graphic product...
