...CRITICAL FIRE WEATHER AREA FOR SOUTHEAST NEW MEXICO...SOUTHWEST
TO NORTHWEST TEXAS...AND CENTRAL OKLAHOMA...
A strong, closed mid-level low will move east across the
south-central United States. As this occurs, a deep surface cyclone
will slowly fill as it moves from southeast Colorado at the start of
the period to central Oklahoma by late evening to southwest Missouri
by the end of the period.
...Eastern New Mexico, Central and Western Texas, Oklahoma, and
A strong mid-level jet will remain wrapped around the aforementioned
mid-level low as it moves across the central United States.
Subsidence beneath the core of the mid-level jet should allow for
strong diurnal heating and mixing across much of the region.
Vertical mixing stemming from this diurnal heating will allow strong
winds within the jet core to mix to the surface. The result will be
a large area of strong, gusty surface winds in the 20-30 mph range,
with even stronger gusts. Mixing and warming will also allow
relative humidity to fall to between 10-20% resulting in widespread
critical fire-weather conditions.
Surrounding the critical fire-weather conditions, slightly higher
relative-humidity values will be a mitigating factor, however
elevated fire-weather conditions will occur.
