DISCUSSION...

KEY MESSAGES:

-  Warming and drying trend through early next week.

High pressure will strengthen and build into early next week,
bringing a significant warm up and generally dry conditions.
Monday looks like the hottest day this week with many valleys
reaching into the low 90s and nearing 100 for the lower valleys of
north central Idaho. Isolated thunderstorms will be possible
across Lemhi County and southwest Montana by Monday and Tuesday
afternoons.

Ensemble forecast models are trying to show a pattern change mid
to late next week. With a trough digging over the west coast,
forcing the subtropical high (four-corners high) west into the
Pacific. The question becomes what is the moisture source as this
pattern would favor wide-scale subsidence over the eastern
Pacific. More to come as this forecast evolves.


&&

.AVIATION...A weak wave will allow for breezy west to northwest
winds late afternoon into the evening today. An isolated shower or
thunderstorm is possible in northwest MT as well, due to the low
probability no showers are currently mentioned in KGPI`s Terminal
Area Forecast. High pressure will build on Saturday producing VFR
conditions.
