Area Forecast Discussion
National Weather Service Missoula MT
235 PM MDT Fri Aug 26 2016

.DISCUSSION...Tomorrow will be a warm and breezy day, so forecast
winds were increased mainly in central Idaho. As a result of the
increased winds, a Red Flag warning was also issued for the Hells
Canyon and Camas Prairie areas in central Idaho. Otherwise there
was little change to the forecast. While it will be dry and breezy
across western Montana with difficult weather for fire fighting,
conditions aren`t yet bad enough to warrant a red flag warning in
those areas.

A series of shortwaves starting Tuesday with one
right after the next through the end of the week will cause an
increasing chance of afternoon thunderstorms. Combined with an
overall dry air mass and a breezy weather pattern, the main
concern next week will be for fire weather.

Honing in on the worst periods next week is difficult due to
tropical storms giving the global weather models difficulty, and
causing a lot of run to run variation. However, it is possible
conditions will line up for another red flag warning next week.


.AVIATION...Light winds are expected at most airfields today. An
exception would be sites in high valleys, such as KBTM, where
later this afternoon occasional gusts 15 to 20 kts could occur.
Thin, high cirrus clouds with mid-level cumulus over mountain
ranges should be of minimal impact. Tomorrow, winds will increase
in strength late Saturday morning and into the afternoon as
southwesterly flow increases.


ID...Red Flag Warning from 1 PM to 9 PM PDT Saturday Palouse/Hells
