.PREV DISCUSSION... /issued 301 AM MDT Sat Apr 29 2017/

SHORT TERM...Today through Monday night.
Should have dry conditions today as upper level ridge works in
from west. Weak Pacific wave will top ridge Sunday and may see
some isolated to scattered showers with snow levels increasing to
7 thousand feet. Scattered showers will continue mainly in the
mountains Monday with cooler conditions. High temperatures will
warm both today and Sunday with Sunday`s highs well above normal.
GK.

LONG TERM...Tuesday through Saturday night. Models still consistent
with a major upper ridge over the west drying out the region Wed and
Thu...along with warmer temps. Snow showers are expected to linger
over the eastern and upper Snake Highlands on Tue in the wake of a
departing upper trof. Models have slowed the next trof an the end of
the week...with precip now expected to arrive on Fri. Models differ
quite a bit in handling the end of the week system...but the
resulting precip solution is fairly similar. The disorganized nature
of the system would suggest precip favoring the mtns Fri thru Sat
night...with light amounts. Snow levels look to remain fairly high.
Hedges

AVIATION...Upper ridging building into the Pac NW today is expected
to result in VFR conditions thru tonight. Hedges

Note: Data outage continues at the KDIJ wx station which limits our
sfc observational data in that area, thus we continue to carry AMD
NOT SKED for that terminal. This is a non-NWS station, and we have
no info on when the issue will be resolved.
