Areas affected...Northeast NE...Southeast SD...Southern MN

Concerning...Heavy snow

Valid 031202Z - 031800Z

SUMMARY...An area of snow, with snowfall rates peaking in the 1 to 2
inches per hour range will continue in northern Nebraska. The
heavier bands will gradually develop northeastward across
southeastern South Dakota and southern Minnesota this morning.

DISCUSSION...Latest mosaic radar over the central and northern
Plains, shows a large area of precipitation from parts of
west-central Nebraska extending east-northeastward across northern
Nebraska into southeast South Dakota and northwest Iowa. Surface
temperatures are generally below freezing across Nebraska, where
most of the precipitation is in the form of snow. At upper levels, a
low is located over southern Nebraska with strong divergence present
from northeastern Nebraska into southern Minnesota. This, combined
with strong low-level convergence, will signal an area of enhanced
lift along and to the northwest of the upper low track. As a result,
isentropic lift will become maximized over the next few hours and
snowfall rates could exceed one inch per hour. A few lightning
strikes will be possible within the heavier bands. As the
upper-level low moves northeastward, heavy snow will develop
northeastward from parts of northeast Nebraska into southeastern
South Dakota and southern Minnesota early this morning.
