218 PM MST Wed Feb 20 2019
.DISCUSSION...Steady light snowfall (occasionally moderate
snowfall in local areas) will continue until around 7 pm this

in msot areas. After 7 pm, just mainly periods of lighter snow or
flurries can be expected until around midnight. After a 6 hour
respite from the snow, a weather system within the southern stream
of the jet stream will send some snow northward which will mainly
affect the Salt and Wyoming Range Thursday afternoon and night
with 2 to 3 inches of snow expected in those areas. Areas north of
Salt River Pass will likely just see less than an inch of snow
from this next event.
