No substantial changes have been made to the critical area across
parts of central/southern NM and far west TX or to the surrounding
elevated area across portions of the Southwest and southern Plains.
See the previous discussion below for more information.

An elevated area has been introduced for portions of the FL
peninsula. A modest strengthening of the surface pressure gradient
across FL will occur through Thursday afternoon as a cold front
moves across the Southeast. Southerly winds should increase to
around 10 mph, locally higher, as RH values fall below 40%. Amidst
dry fuels, these meteorological conditions will support an elevated
fire weather threat.

The fire weather story remains much the same on Thursday as the
previous few days. Strong west/northwesterly deep-layer flow will
overspread much of the southern tier of the U.S. as a broad upper
trough encompasses the middle of the CONUS. A strengthening surface
low over the southern/central High Plains with higher pressure near
the Pacific coast will result in a modest pressure gradient across
the southwestern states to the southern High Plains. Gusty winds
aligned with dry conditions will again lead to elevated to critical
fire weather concerns across parts of AZ/NM and western TX.

...Portions of AZ, much of NM into western TX...

Fuel conditions continue to add a question mark to the eastern
extent of critical delineation.  Green-up continues across west TX
into the eastern plains of NM. For now, highest confidence in the
overlap of strong winds, low RH and at least areas of available
fuels has been noted by the critical area across parts of the
southern/central NM into far west TX. Here, westerly surface winds
25-35 mph with higher gusts are expected and RH values falling into
the 7-15 percent range are expected. These meteorological conditions
will spread east into parts of the TX Panhandle and TX South Plains
to the Concho Valley, but again, concerns over available fuels will
preclude critical delineation here. 

Further west across parts of northern and eastern AZ into northern
NM, winds will be slightly lower and RH values will range from 15-25
percent. Some spotty/brief critical conditions will be possible but
less widespread compared to further east.
