Spot Forecast for Upper Santa Clara Piles
National Weather Service Salt Lake City UT
810 AM MDT Thu Mar 23 2017

.DISCUSSION...Today will continue to see unsettled conditions with
rain showers transitioning to snow showers throughout the day.
Precipitation is anticipated to end by 7pm with high pressure
building in for Friday. Winds may become gusty late today into the
evening hours from the northwest as the precipitation band banks
up against the terrain across southwest Utah, near the burn site.
The flow aloft will become calmer, and thus clearing index for
Friday will not be favorable to burn with values well below 500.
The airmass will see a very short drying trend for Friday.
Saturday will see a return to deep mixing aloft with clearing
index values back well above 500 and southwesterly winds aloft.
Chances for precipitation return late Saturday, and chances for a
rain/snow mix will return.
