Valid 191200Z - 201200Z

No changes were made to the forecast for Saturday. Some uncertainty
remains in timing of cold front passage across the Trans-Pecos area
affecting residence time of Elevated fire weather conditions. Higher
confidence of an Elevated to a locally Critical fire weather threat
will exist across the Big Bend area with southwest winds of 15-20
mph and relative humidity dropping to below 10 percent at times,
before conditions moderate for Saturday evening behind the cold
front.

...Synopsis...
An upper-level trough will eject into the southern Plains on
Saturday, though it will lose some amplitude during the period. A
cold front will continue southward into more of the southern High
Plains and eventually the Permian Basin. A surface low near the
Trans-Pecos/Big Bend will deepen during the day before weakening
during the evening as the trough lifts northeastward.

...Trans-Pecos/Big Bend...
Though cooler/moist air to the east and north will limit the areal
extent, elevated fire weather will occur within the Trans-Pecos and
Big Bend Saturday afternoon. Moderate to strong mid-level winds will
remain in the region during the afternoon and the surface low will
also be deepest during the favorable diurnal heating maximum. Cloud
cover should be minimal in this area given the presence of dry air
aloft. Surface winds of 15-20 mph are likely along with RH of 5-20%.
Areas of southeast New Mexico into the South Plains could see
briefly elevated conditions, but uncertainty in duration is too
great for highlights.

...Florida...
Continued dry easterly flow will once again promote elevated fire
weather along the western Peninsula during the afternoon. Models
indicate winds could be slightly stronger than on Friday (10-15
mph). RH will fall to similar levels, however (25-35% anticipated by
the afternoon. Very dry fuels will support fire spread.
