Spot Forecast for Bennion Canyon Rx
National Weather Service Salt Lake City UT

.DISCUSSION...High pressure over Utah will lead to relatively
light winds and poor mixing today, resulting in low clearing
index values. Clouds will increase starting late this afternoon,
and south winds will begin to increase Thursday morning, both
ahead of an approaching storm system.

This storm will bring an increasing chance of rain on Thursday,
with the associated cold front expected to move through the
project site between 1400 and 1700 local time. This will bring a
strong shift to northwesterly winds and a burst of precipitation,
with a chance of thunderstorms, as well as snow levels likely
lowering to the project site by the late afternoon or early
evening. The chance of precipitation and gusty northerly winds
will persist through Friday before the storm exits Friday night.
