.SHORT TERM...Today through Wednesday night...Our upper level
flow will be out of the northwest to start the short term, then
shift to zonal Tuesday, then to just south of west Tuesday night
through Wednesday night. This will be a dry flow, and no
precipitation is forecast through the short term period. Winds
will be breezy from around Mountain Home east into the western
Magic Valley today, but otherwise winds will be light and follow
typical diurnal trends for this time of year. Temps will be 5-10
degrees above normal today and Wednesday, with a warmer Tuesday
(10-15 degrees above normal) sandwiched in-between.

.LONG TERM...Thursday through Monday...The upper flow will
become more southwesterly Thursday as a large upper level low
moves into position off the Canadian coast. This will bring
warmer temperatures Thu (10-15 above normal) and Fri (5-10 above
normal). As the upper system moves inland late Friday into
Saturday, it is expected to push an initial cold front through
the area Friday, followed by a stronger front Saturday. These
will push temps down to just below normal Saturday and around 5
degrees below normal Sunday. These fronts look dry and breezy
at this time. Models agree quite well into Friday, but differ in
the strength of the weekend system. The latest EC depicts a
strong trough passage Sunday, while the GFS holds it back until
late Monday. At this time, a slight warming is anticipated for
Monday in the NBM guidance, indicating that ensembles favor the
EC timing over the GFS.
