Areas affected...Northwest Nebraska and southwest South Dakota

Concerning...Blizzard 

Valid 141740Z - 142145Z

SUMMARY...Heavy snow and blizzard conditions are expected through
the afternoon.

DISCUSSION...Snowfall rates have increased substantially across
northwest Nebraska and southwest South Dakota over the last hour.
Expect snowfall rates to continue to increase and persist through
the afternoon as strong 700mb warm air advection continues across
the region. In addition to the very heavy snowfall rates,
blizzard/near blizzard conditions are ongoing across the region.
Winds are around 25 to 30 knots with gusts 35 to 45 knots.
Visibilities are currently 1/4 mi and 1/2 mi across northwest
Nebraska and southwest South Dakota, but less than 1/4 mi visibility
is likely in the next few hours. South central South Dakota/north
central Nebraska currently have temperatures in the upper 30s with
rain, but rain should change to snow across these areas in the next
few hours as cooler temperatures aloft move eastward.
