Spot Forecast for DWR Unit 9 Rx...State of Utah Forestry Fire and State Lands
National Weather Service Salt Lake City UT
1103 AM MDT Tue Apr 23 2024

Forecast is based on ignition time of 1500 MDT on April 23.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...Surface inversions will be in place through ~10-11am, so poor clearing before this time
will limit ventilation. Guidance suggests these inversions will
break by mid to late morning with afternoon CLR 500+, but a few
members suggest these inversions stay in place depending on how
far out on the water the burn location extends. Morning clouds
should give way to mostly clear skies in the mid to later morning,
similar to today. Relative humidities will be dropping below 30%
as surface temperatures increase throughout the day. However,
winds will be relatively light out of the south/southwest ~6-8
mph. Can`t rule out an isolated afternoon shower as a storm to our
west approaches (~20% chance) with some building cumulus clouds
during the afternoon. These clouds should stay limited to ~35%
coverage. More widespread rain arrives Thursday/Friday.
