.DISCUSSION...
Weather at the spot location will trend warmer and be relatively clear through the midweek as high pressure builds.
A weak low pressure wave Tuesday afternoon may support virga/showers in the lower Snake Plain, although confidence is low.
Any gust fronts from showers should come out of the northwest and be weak by the time they reach the site.
Winds are calmer on Wednesday, but will pick up again Thursday afternoon as a low pressure system moves south along the West Coast.
Precipitation chances also increase as the low approaches, mainly Friday afternoon/evening.
