Spot Forecast for Fair Piles...USFS
National Weather Service Denver/Boulder CO
447 AM MST Wed Nov 6 2024

If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION... There will be light snow that falls throughout the
day today. Generally 1-3" is forecast but there could be higher
amounts across the higher terrain of the burn. Winds will gust up
to 16 mph this afternoon which may create just enough mixing for
fair smoke dispersal to develop.

The chance for snow becomes minimal tonight and into Thursday. The
majority of the hours should be dry but up to an additional inch
cannot be ruled out for tomorrow. Lighter winds tomorrow should
keep smoke dispersal poor.
