Administrators NorthGeorgiaWX Posted December 26, 2023 Administrators Share Posted December 26, 2023 MD 2349 CONCERNING FREEZING RAIN FOR MUCH OF EASTERN NORTH DAKOTA...NORTH-CENTRAL SOUTH DAKOTA Mesoscale Discussion 2349 NWS Storm Prediction Center Norman OK 0527 AM CST Tue Dec 26 2023 Areas affected...much of eastern North Dakota...north-central South Dakota Concerning...Freezing rain Valid 261127Z - 261630Z SUMMARY...Freezing rain, mixed occasionally with sleet, should continue across much of the discussion area through mid morning. Ice accumulations may exceed 0.05 inches/3 hours. DISCUSSION...An area of freezing rain, mixed at times with sleet, continues across the discussion area as of 1120z. The precipitation is supported by ample warm/moist advection and large-scale ascent associated with lobes of vorticity rotating around the expansive central Plains cyclone. Latest short-term deterministic and ensemble guidance reflects high probabilities of freezing rain continuing as the dominant precip type through mid morning. This is supported by RAP-based forecast soundings generally showing a warm nose between 900 and 800 mb where surface wet bulb temperatures are below freezing. Continued low- and mid-level moisture transport should result in freezing rain accumulations in excess of 0.05 inches/3 hours in many areas through 15z. ..Bunting.. 12/26/2023 ...Please see www.spc.noaa.gov for graphic product...
