Elevated fire weather is possible on Tuesday along the far western
Panhandles.

Strong westerly to southwesterly winds are expected Wednesday,
with a Wind Advisory or High Wind Warning perhaps being needed.

Critical fire weather conditions are likely to develop Wednesday

Panhandles, due to strong southwesterly winds, low relative
humidity values, and dry fuels.

Areas of blowing dust are possible across a majority of the
western and central Texas Panhandle Wednesday. Any blowing dust
will reduce visibilities at times.
