MD 2255 CONCERNING HEAVY SNOW FOR PORTIONS OF NORTHERN INTO CENTRAL MINNESOTA
Mesoscale Discussion 2255
NWS Storm Prediction Center Norman OK
1156 AM CST Tue Dec 09 2025
Areas affected...portions of northern into central Minnesota
Concerning...Heavy snow
Valid 091756Z - 092300Z
SUMMARY...Moderate to heavy snow is expected to begin over the next
few hours. 1 inch/hour snowfall rates are possible.
DISCUSSION...A surface-850 mb low is beginning to intensify while
shifting southeastward across ND, which is resulting in increased
low-level warm-air/moisture advection within a sub-freezing
troposphere over northern to central MN. A primary band of at least
light to moderate snow is already in place along the ND/MN border,
and this band is expected to intensify with increased 850-700 mb
frontogenesis over central MN over the next several hours. Increased
saturation of the dendritic growth zone should support widespread
moderate snowfall rates, but at least a few instances of heavy snow
are possible, including snowfall rates locally exceeding 1
inch/hour.
