.DISCUSSION...Transient weak high pressure builds over northern Utah through
the day today, bringing partially stable, dry, and warm
conditions over the burn site today. Elevated moisture will bring
mid and high level cloud cover late this morning through much of
the day, as well as isolated high-based showers. It is very
unlikely (less than 5 percent chance) that any precipitation will
reach the ground, however, gusty winds will still be possible with
passing elevated showers.

For Saturday, southwest flow will increase over the area as a
weak cold front approaches Utah. Temperatures will warm under the
southerly flow and relative humidity will be on the downward
trend. That said, elevated moisture and deeper afternoon mixing
will bring increased coverage of elevated showers. With greater
coverage of showers, there is increased potential for
precipitation reaching the ground, as well as an increased threat
of gusty and erratic outflow winds. There is virtually zero chance
for wetting rains. The aforementioned cold front is anticipated
to push through the burn area around 1700, shifting winds to a
northwesterly direction.
