Area Forecast Discussion
National Weather Service Missoula MT
225 PM MDT FRI JUL 31 2015

...Very Hot Saturday and Sunday...
...Threat of Thunderstorms Monday and Tuesday...

.DISCUSSION...A very hot air mass will impact the northern Rockies
through Sunday. Temperatures should peak most areas (Orofino,
Grangeville eastward across Libby, Kalispell, Seeley Lake, Missoula,
Hamilton, Salmon, Anaconda, Butte) on Sunday about 10 to 15
degrees above normal...but a few degrees shy of records.

Critical fire weather conditions are also expected, especially
across northwest Montana where very dry fuel conditions/fire
danger will be further exaggerated by very low relative humidity,
the heat, local breezy conditions, and an unstable atmosphere
Saturday afternoon.

Moisture should start to shift over north central Idaho and
western Montana Sunday night with further moistening of the air
mass into Tuesday. This should translate into an increasing chance
of thunderstorms by early next week. Initially the storms may not
produce much precipitation. However, as the air mass moistens,
more showers are expected to develop with time...into Tuesday.  


.AVIATION....Clear skies and light diurnal afternoon/evening
winds are expected into tonight for all area terminals under
persistent high pressure.


MT...FIRE WEATHER WATCH from Saturday afternoon through Saturday 
     evening Flathead/Glacier Park...Kootenai...Salish and 
     Kootenai Reservation...West Lolo.
