...CRITICAL FIRE WEATHER AREA FOR PARTS OF THE NORTHERN SIERRA INTO
THE HARNEY BASIN...
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF FAR NORTHERN
MONTANA...

...Synopsis...
An upper ridge will remain in place across the western CONUS today,
with strong mid-level flow cresting the ridge across the West Coast
into the northern Rockies. A dry and deep boundary layer will
encourage downward mixing of this stronger flow aloft along the
periphery of the ridge by afternoon peak heating. A broad area of at
least 15 mph sustained southwesterly surface winds amid 20 percent
RH will overspread portions of the western Great Basin into northern
High Plains, warranting Elevated highlights given dry fuels.
Guidance consensus also depicts locally stronger winds across
portions of northern Montana, and parts of the northern Sierra into
the Harney Basin, justifying the continuation of Critical
highlights.

Another day of scattered, potentially high-based thunderstorms are
expected across portions of southern Montana. However, given less
receptive fuels in this area, especially with some accumulated
rainfall from the prior day`s storms, it is unclear how efficient
lightning-induced ignitions will be. Therefore, isolated dry
thunderstorm highlights have been withheld this outlook.
