324 AM MDT Tue Apr 24 2018

.SHORT TERM...Today through Wednesday...A high amplitude upper
ridge will remain positioned over the Pacific NW through
Wednesday. The dry, stable air mass will keep clear skies over
the region for this period. Breezy conditions today as a surface
high over MT pushes easterly winds through the Snake River Plain
and highlands of southwest Idaho into southeast Oregon. Winds
slacken some on Wednesday as the high pulls east. Temperatures
warm around 5F degrees each day.

.LONG TERM...Wednesday night through Monday...Warm temperatures
will continue through Friday. Thursday will be mostly sunny, but
on Friday an upper level low pressure trough will move over the
west coast, providing enough moisture and instability for isolated
showers and thunderstorms as far inland as southeast Oregon and
southwest Idaho. Models agree on moving the trough over the
Intermountain Region Saturday and Sunday, displacing the ridge and
bringing cooler air and scattered showers, along with isolated
mainly afternoon and evening thunderstorms. High temperatures will
be around 15 degrees above normal Thursday and Friday, then cool
to around 5 degrees below normal by Sunday. The trough will remain
over our area through Monday, then begin a slow exit on Tuesday.

.AVIATION...VFR with mostly clear skies. Surface winds southeast
5-15 kts. Winds aloft to 10k feet MSL, northeast to east 10-20
kts.
