Areas affected...Parts of southeastern MN and western WI

Concerning...Heavy snow=20

Valid 031923Z - 032330Z

SUMMARY...A band of heavy snow with rates up to 1 in/hr will
continue spreading northeastward across parts of southeastern MN
into western WI this afternoon.

DISCUSSION...Water-vapor imagery shows a closed mid-level low moving
slowly northeastward over eastern NE, with strong DCVA overspreading
a low-level baroclinic zone across MN and WI. The resulting
isentropic ascent/frontogenetic forcing is leading to a band of
heavy snow across parts of southeastern MN. Deep, saturated
thermodynamic profiles with strong ascent in the dendritic growth
zone should continue favoring heavy snowfall rates across
southeastern MN into western WI this afternoon. Snowfall rates up to
1 in/hr are expected with this snow band. Further south over
southern MN, warmer temperatures at 850 mb are yielding mixed winter
precipitation given sufficiently cold surface temperatures.
