...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF NORTHWEST NEVADA...

...Synopsis...
The upper-level trough in the Northwest will continue to dig
southward through the day on Monday. Some increase in the mid-level
jet is expected to occur from northwest Nevada into the northern
Rockies. A surface low will deepen in the northern Great Basin.

...Central/northern Great Basin into western Wyoming...
A broad area of elevated fire weather conditions are expected across
these regions. Surface winds will reach 15-20 mph in most locations,
though areas of higher speeds are possible in terrain-favored areas.
Single digit RH is possible in parts of central/northern Nevada, but
15-20% will be more common elsewhere.

Critical conditions are expected along the Sierra Front in northwest
Nevada. Here, the mid-level jet will enhance winds aloft during the
afternoon. While the surface low will not be overly deep, the
combination of these factors will support winds around 20 mph near
the terrain. Gusts to around 30 mph are also possible. There is some
potential for high level clouds to limit RH reductions. Even with
some of these marginal factors, wind speeds should be sufficient to
promote rapid fire spread in fuels that are very dry (ERCs above
90th percentile).
