...CRITICAL FIRE WEATHER AREA FOR NORTHERN ARIZONA INTO NORTHWEST
NEW MEXICO...

...Synopsis...
An upper trough over the Four Corners region will shift east into
the Plains this afternoon. Meanwhile, a shortwave trough will
migrate across the Great Basin to the Rockies. This will lead to
enhanced westerly deep-layer flow across much of the Great Basin and
southwestern deserts. Furthermore, strengthening surface low
pressure from the northern High Plains to the Four Corners will
allow for increasing southwesterly low level winds. Where fuels are
dry, elevated to critical conditions are expected across parts of
the southwestern U.S.

...Far southern NV, far southern UT, far southwest CO, northwest NM,
and northern AZ...

As temperatures climb into the 80s to near 90 degrees in lower
elevations, RH values will drop into the 7-15 percent range. As this
occurs, southwesterly surface winds will increase to 20-25 mph with
higher gusts. Where fuels are dry, this will lead to several hours
of elevated to critical fire weather conditions from late morning
through the afternoon. Wind speeds should decrease during the
evening hours and RH values will recover to the 20-40 percent range
overnight.
