Spot Forecast for South Canyon Ponderosa RX...BLM
National Weather Service Salt Lake City UT
957 AM MST Mon Nov 10 2025

Forecast is based on ignition time of 1000 MST on November 10.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...Dry stable conditions will continue under the influence of high
pressure centered over the west. This will result in poor
ventilation as winds aloft remain weak and thermal inversions stay
in place, limiting diurnal mixing. Winds will be light and
terrain drive Monday and Tuesday. This pattern is slated to start
changing by Wednesday ahead of an approaching storm moving towards
the west coast. On Wednesday, ahead of this storm, southwest
winds will start to increase and become gusty. This will provide
for better mixing and good ventilation, however, relative humidity
will stay on the lower side as dry air blows over the area ahead
of this storm that is expected (70% chance) to deliver widespread
precipitation late in the week and into the weekend as it gets
closer.
