   Areas affected...Southeastern Nebraska

   Concerning...Heavy snow 

   Valid 231952Z - 240045Z

   SUMMARY...Heavy snow rates of 1-2 inches/hour are possible in
   portions of southeastern Nebraska this afternoon/early evening. Snow
   rates should generally taper off by 6-7 pm CST. An intensifying
   surface pressure gradient is also expected and may yield blizzard
   conditions in some areas later tonight.

   DISCUSSION...A band of heavy snow has developed along a line from
   Hastings to York in response to strong mid- and upper-level ascent
   from a vigorous shortwave trough now over western Kansas. This
   ascent should continue to progress to the northeast through the rest
   of the afternoon, coincident with saturated DGZs in RAP forecast
   soundings. Heavy snow rates of 1 inch/hour, with some areas locally
   higher, will be possible through about 6-7 pm CST. A deepening
   surface cyclone now in south-central Kansas will also move off to
   the northeast this evening. As this occurs, a strengthening surface
   pressure gradient may yield blizzard conditions even as heavier snow
   rates wane.
