   ...D3/Thu - Portions of the Great Basin into the Northern Rockies...
   A fast-moving, mid-level trough will move through the Northwest and
   into the Northern Rockies on Thursday. This trough will strengthen
   mid-level flow somewhat across the Great Basin and northern Rockies.
   Where a dry, deeply mixed boundary layer is expected across most of
   the Great Basin, winds should strengthen into the 15 to 20 mph range
   with relative humidity around 10 to 15 percent. Therefore, 40%
   critical probabilities have been included across a broad portion of
   this region to cover the threat.

   In addition, these conditions are also expected in the Snake River
   Valley, but lighter winds and more moist conditions are expected
   between this area and the fire weather concerns in northern Utah and
   southwest Wyoming. Therefore, a separate 40% area has been added for
   the Snake River Valley.

   ...D5/6-Sat/Sun - Northern Great Basin into far northern Colorado
   and southern Wyoming...
   A strong upper-level jet is expected to overspread the Pacific
   Northwest and northern Rockies on Saturday and Sunday. Much of the
   Pacific Northwest and northern Rockies will be cool and moist enough
   to avoid the primary fire weather concerns, but strong winds are
   expected to develop in the dry areas from northeast Nevada eastward
   into southeast Wyoming. There are still some uncertainties regarding
   the amplitude of the trough which preclude higher critical
   probabilities, but there is enough consistency between model
   solutions to warrant a 40% probability on both days.
