   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHEAST ARIZONA INTO
   SOUTHERN AND CENTRAL NEW MEXICO...FAR WEST TEXAS...

   ...Synopsis...
   A mid-level impulse embedded within larger-scale cyclonic flow
   (associated with a near stationary mid-level shortwave trough) is
   poised to traverse the Four Corners region during the afternoon
   hours. Over 50 knots of 500 mb flow will accompany this impulse as
   it rides atop a deeply mixed boundary layer, where downward momentum
   transport of the flow aloft may occur. Deep boundary layer mixing,
   combined with isallobaric flow associated with a surface lee trough
   fortified across the High Plains, will both induce very dry, windy
   conditions across much of the Four Corners area, where conditions
   will be favorable for fire spread.

   Meanwhile, across the southeast CONUS, large scale ridging aloft,
   with surface high pressure, will be the predominant weather pattern
   throughout the day, with large-scale subsidence and relatively
   hot/dry conditions in place.

   ...Southeast Arizona into southern/central New Mexico, far West
   Texas...
   By peak afternoon heating/boundary layer mixing, widespread 20+ mph
   sustained southwesterly surface winds amidst 10-20% RH will be
   common across much of southeast Arizona into most of New Mexico and
   far West Texas, where both elevated and critical delineations are in
   place. Many places in central into southern New Mexico will likely
   see sustained winds reach the 30-35 mph at times. Despite these
   winds coinciding critically low RH, an extremely critical
   delineation was withheld given the relatively modest receptiveness
   of fuels to fire spread. Later in the evening, nocturnal cooling of
   the boundary layer will result in decreasing wind speeds and
   increased surface RH, tempering wildfire-spread potential.

   ...Far southeast Alabama into southern Georgia, far northern
   Florida, far southwest South Carolina...
   By mid afternoon, temperatures are expected to climb well into the
   90s, with RH dropping below 35% in some locales. The region has been
   relatively devoid of precipitation for at least the past week, and
   with no rainfall forecast in the immediate future. These hot, dry
   conditions will promote the continued curing of fuels. Elevated
   delineations are currently being withheld given the lack of stronger
   winds across the region, though 10-15 mph wind gusts associated with
   sea breezes may potentially induce locally elevated conditions
   during the afternoon hours.
