   Areas affected...Southeast ID...Northeast NV...Northern UT

   Concerning...Snow Squall 

   Valid 262230Z - 270030Z

   SUMMARY...A snow squall producing brief blizzard-like conditions
   should progress east-southeast before weakening after about 00-01Z.

   DISCUSSION...Surface observations and radar reflectivity confirm the
   presence of a snow squall along a cold front across a portion of the
   Snake Valley in south-central ID extending west-southwest across
   north-central NV. TWF measured a gust to 52 kt at 2141Z with less
   than quarter-mile visibility in snow reported in the most recent
   observation. JER also recorded a 35 kt gust at 2152Z with
   quarter-mile visibility in snow. The snow squall is being supported
   by a steep low-level lapse environment ahead of and along the front,
   in addition to strong low-level northwesterlies behind the front per
   time-series of CBX VWP data. Short-term guidance suggests this
   strong flow regime is likely greatest now at peak heating and should
   subside through the evening. 12Z HREF members and recent HRRR runs
   that suggested the potential for a snow squall also indicate a
   weakening trend to the squall after about 00-01Z. Until that time,
   the squall may affect portions of the I-84 and I-15 corridors in ID
   and far northern UT, and the I-80 corridor in NV.
