Spot Forecast for Pine Valley Rx Piles...USFS
National Weather Service Salt Lake City UT
1129 AM MST Wed Dec 4 2024

Forecast is based on ignition time of 1000 MST on December 04.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...Stable conditions remain in place over the burn area through
the next several days as broad high pressure dominates the
western U.S. Expect low mixing heights during the afternoon hours
and light flow to lead to poor clearing in the lower elevations.
Poor to fair clearing is expected on the mid-to-upper slopes
outside of the inversion layer, however, flow is still expected to
be limited. Winds will generally follow light terrain driven flows
during the overnight hours and on mid-to-upper slopes while the
lower valley floor and drainages will be light and variable during
the afternoon. Clear skies prevail through the day today, however, will
see increasing upper level cloud cover during the early morning hours
on Thursday, persisting through much of the day.
