Area Forecast Discussion
National Weather Service Missoula MT
121 AM MDT Fri Jul 26 2024

.UPDATE...No major updates needed to previous discussion. Weather,
messaging, and impacts remain steady.

&&

.DISCUSSION...Winds remain elevated Friday through the forecast
period as progressive, west to east flow, continues over the
region. Dry air, currently over northwest Montana, will mix into
the entire region during the day and Minimum humidities return to
the teens and lower 20s.

Sunday, a weak cold front pushes through the region. Currently,
beyond the ongoing background afternoon breezes no impacts are
expected, but keep checking future forecasts.

The next system on Tuesday, will traverse the Canadian border and
bring the threat of showers and thunderstorms to northwest MT.
Continuing the theme, the rest of the region will have elevated
afternoon breezes with dry conditions.

Looking long term: The southwest high pressure ridge is expected
to rebuild and quickly get knocked down by another powerful
Alaskan trough the weekend of 2-3 Aug. This is supported by 100%
of the models, the main variance within the guidance is depth of
the Alaskan trough and speed of breakdown. We will be monitoring
the evolution of this weather event closely.


&&

.AVIATION...Breezy winds out of the west will develop this afternoon
and evening and will be the main weather feature at all terminals
today. Smoke from local and regional wildfires will degrade
visibility across the board throughout the Northern Rockies today
and tonight.
