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.
