.DISCUSSION...The ridge that has been near the Utah/Nevada border
over the past few days will shift east today, moving directly over
Utah this afternoon. Western portions of Utah, including the fire,
will find itself under a south to southwest flow for much of
today, allowing deeper moisture from the south to stream
northward, allowing for scattered showers and thunderstorms to
develop this afternoon. With a trough moving onshore along the
Pacific Northwest coast today, shortwave energy ejecting from this
system will move into the vicinity of the fire later today and
into tonight, allowing for coverage of showers to increase further
this evening and overnight. Showers will remain fairly widespread
in the vicinity of the fire through Thursday before drier air
begins to move in beginning Friday.
