...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF EASTERN NEVADA INTO
WESTERN UTAH AND NORTHERN ARIZONA...

...Synopsis...
A deepening mid-level wave will bring an increase in winds and
potential for dry thunderstorms across the Great Basin on Tuesday.
Elevated to Critical conditions can be expected in portions of
eastern Nevada, western Utah, northern Arizona and southern Idaho.

...Eastern Nevada, western Utah, northern Arizona...
Increasing southwesterly flow around 10-20 mph will overlap with
afternoon relative humidity reductions to around 10-15 percent on
Tuesday afternoon. The best overlap of Critical winds and relative
humidity appears to be across eastern Nevada into western Utah.
Further south into northern Arizona and the Arizona Strip, winds may
be at or just below Critical thresholds. However, ongoing fires with
a history of erratic fire behavior warrant inclusion into the
Critical area. Gusty and erratic winds from nearby thunderstorms
will also be possible.

...Dry Thunderstorms...
Isolated dry thunderstorms will be possible on the periphery of
deeper monsoonal moisture across portions of northern Arizona into
western Colorado, Utah, far southern Idaho, western Wyoming, and
Nevada. Within these regions, PWs generally around 0.25-0.50" are
expected with moisture remaining primarily mid-level with drier
boundary layer conditions below. This will promote high based
convection with little precipitation amid faster storm motions with
the mid-level trough passage. Fuels within these regions are
receptive to ignition and as such an isolated dry thunder area was
maintained with this outlook.
