.DISCUSSION...Idaho currently under the influence of a dry zonal
flow. An upstream trough will advance into the PAC NW tomorrow
evening with the surface front pushing through east Idaho by
Monday morning. Very little precipitation is expected, but winds
along and behind the front will be strong...about 25 to 30 mph
across the Upper Snake Plain and the Central Mountains. Winds will
be slightly weaker on Tuesday as the pressure gradient lets up a
bit. Both GFS and ECMWF are hinting at a bit of energy coming out
of Canada Wednesday night impacting the Central Mountains and the
Island Park area, so nudge up PoPs Wednesday as well as Thursday.
Have also dropped temps a couple degrees accounting for the
increased influence of Canadian air. The upper trough finally
shifts eastward Friday as we return to dry conditions. Hinsberger
