...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTH TEXAS...
A mid/upper closed low will slide east across the Gulf Coast states,
deepening as it reaches Georgia/Carolinas and a strong jet streak
rotates around its southeastern periphery. In its wake, strong
northwesterly 850-700 mb flow will overspread much of southern
Texas, as heights build across the Desert Southwest. At the surface,
a low will rapidly transit east from Arkansas to the southern
...Portions of southern Texas and the southern high Plains...
High pressure building into the southwest states will combine with
the deepening low over the southeast to strengthen the surface
pressure gradient considerably across much of the southern Plains.
Northwesterly winds sustained around 30-35 mph will develop over
much of southern and central Texas, while winds will be slightly
lower over western Texas and eastern New Mexico. Deep mixing will
encourage strong gusts upwards of 50 mph, primarily across southern
Texas. Related downslope warming/drying will lead to widespread RH
values below 20-25 percent as well. Fuels will likely have dried
sufficiently to support critical fire-weather concerns over southern
Texas, especially considering the strength of the flow. To the
northwest, lower winds (20-25 mph sustained) and more marginal fuels
should keep fire-weather concerns at elevated levels.
