...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN IDAHO...

...Synopsis...
A mid-level trough will overspread the northern Rockies while upper
ridging prevails across much of the CONUS today. Adequate
upper-support associated with the passing mid-level trough will
encourage dry and windy conditions across portions of northern
California and the northern Great Basin toward the central Rockies.

Portions of the Sacramento Valley in California will be the first
region impacted by fire weather conditions. 15+ mph sustained
northerly surface winds should already be ongoing by the morning
hours, with RH decreasing to 15 percent by late morning into early
afternoon. Elevated highlights were added to parts of the Sacramento
Valley given receptive fuels in the area. 15+ mph sustained westerly
surface winds will also overlap with a large area of RH dropping
below 15 percent across parts of the Great Basin into the central
Rockies. Fuels are also receptive to wildfire spread in this region,
warranting the maintenance of Elevated highlights. Critical
highlights have also been maintained across portions of the Snake
River Plain in southern Idaho, where westerly surface winds may
sustain well above 20 mph for at least a few hours around afternoon
peak heating.
