Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0203 AM CST Sat Jan 21 2017

Valid 211200Z - 221200Z

...Synopsis...
A strong mid/upper jet will progress from the Desert
Southwest/northern Mexico to the northwest Gulf of Mexico through
the period. As it moves east, a closed low will organize over the
Red River Valley, eventually reaching the ArkLaTex near the end of
the period. In response, a surface cyclone will shift from the Texas
Panhandle east across Oklahoma and into Arkansas.

...Portions of the south Texas Plains...
High pressure will build into northwest Mexico and the Desert
Southwest, such that the pressure gradient over parts of
western/southern Texas tightens through Saturday night. In turn,
westerly winds will increase across much of western and far southern
Texas through the period. Elevated/locally critical fire-weather
concerns will likely remain confined to locations near the Rio
Grande in southern Texas, where downslope drying/warming supports RH
values falling into the 20-25 percent range during the afternoon,
while winds increase to around 20 mph sustained. While even windier
conditions (sustained winds over 30 mph) will exist farther
northwest, higher RH values should preclude greater fire-weather
concerns there.
