.DISCUSSION...A weak upper-level disturbance will drop south out
of Canada late this afternoon, though little moisture will be
associated with it. A few light and isolated showers will be
possible in the Glacier National Park region and extreme
southwestern Montana and Lemhi county. Warm and hot conditions
will continue through the rest of the week and into the weekend.

Not a lot changes in the forecast as we head into the weekend.
There is an increased potential for afternoon and evening
scattered thunderstorms along Silver Bow, Granite, and Lemhi
counties on Saturday, but right now confidence is not very high
that these will be anything other than garden-variety storms.

Sunday still looks to be the warmest day for the Northern Rockies,
with temps ranging well into the mid to upper 90s and low 100s.
Some higher valleys will be the only locations staying "cooler" in
the 80s and low 90s.

Forecast models from Monday onward start to disagree amongst
solutions, leaving our confidence low in trying to decide which to
believe when it comes to precipitation chances and daytime
temperatures. It does look like a very unsettled afternoon both Monday
and Tuesday, so have kept chances for thunderstorms going in the
forecast for these days.


.AVIATION...Conditions will be rather benign for most TAF sites
today, with the exception of KGPI where isolated showers have the
potential to develop in the Glacier National Park region late this
afternoon. Otherwise a fairly nice day with light winds developing
in the afternoon for all aviation sites.
