Spot Forecast for Pingree Hill...USFS
National Weather Service Denver/Boulder CO
632 PM MDT Tue Oct 17 2017

Forecast is based on ignition time of 1800 MDT on October 17.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...A broad upper level ridge will remain in place over
Colorado through Wednesday with light to moderate westerly flow
aloft. Weak pressure gradients at the surface will lead to light
and variable wind fields at low levels. The airmass will remain
dry and unseasonably warm. The light winds at low and mid levels
will be limiting factors to the smoke dispersion through the
afternoon hours. Thursday will feature a little bit more
southwesterly flow aloft with a slight increase in cloud cover.
Winds for both days may be more subject to terrain driven
influences than pressure gradients. Downslope/downvalley winds
will prevail overnight and through the mornings, with
upslope/upvalley winds from midday through the afternoons.
