Mesoscale Discussion 0137
NWS Storm Prediction Center Norman OK
0506 PM CST Tue Mar 04 2025
Areas affected...portions of central into eastern Nebraska
Concerning...Blizzard
Valid 042306Z - 050200Z
SUMMARY...Blizzard conditions are possible over the next few hours.
Moderate to heavy snowfall rates may occur with northwesterly
surface winds sustaining over 40 mph, perhaps gusting to 70 mph.
Visibility may drop to a quarter mile in spots.
DISCUSSION...A surface low along the KS/MO border continues to
deepen while shifting towards the Great Lakes, promoting a broad,
intense northwesterly surface wind field over parts of the central
Plains. Surface observations show northwesterly surface winds
sustaining to 40 mph at times over parts of central/eastern NE,
where measured gusts have exceeded 65 mph. In tandem with these
intense winds are developing snow-bands, as surface-700 mb cold-air
advection continues to cool the column to temperatures below
freezing. The surface low should continue to intensify through the
evening as snowfall rates gradually increase. The current
expectation is for blizzard conditions and reduced visibility to
gradually become more common through the evening.
