Area forecast discussion 
National Weather Service Spokane Washington
926 PM PDT Thursday Aug 28 2014

Synopsis...
a cool down begins across the inland northwest, with an increase
of clouds and locally breezy winds. A weak system will bring a
chance of showers to the Cascades and northern mountains Friday.
Another, stronger system arrives during the Holiday weekend. This
will result in breezy to windy conditions, along with an increased
chance for mountain showers. Temperatures will drop below normal
by the weekend, with low temperatures in the 30s possible Sunday
morning in the northern valleys of Washington and the Idaho
Panhandle.

Discussion...
a strong mid level wave over northwest Montana clipped the north
Idaho Panhandle earlier this evening bring scattered showers and
thunderstorms to a small area between Bonners Ferry and Sandpoint.
Water vapor satellite shows drier air aloft moving into north
Idaho with radar as of 915 PM showing showers out of the area. A
short wave ridge will move over the area tonight in advance of an
approaching upper level trough. This will lead to dry conditions
across the inland northwest although satellite does show high
clouds over and west of the Cascades moving east. Forecast has
been updated to remove the evening shower/thunderstorm wording for
the north Idaho Panhandle...and to make minor sky cover
adjustments. Jw

Aviation...
06z tafs: mostly clear skies with scattered high clouds are
expected tonight as weak high pressure moves over the area. The
next system will spread a thicker deck of mid and high clouds
across the inland northwest Friday afternoon and evening...and
also bring breezy west-southwest winds over the area.
