No significant changes have been made to the going forecast.  All of
the impactful weather in this forecast is expected to be wind-
related, and will occur today.

Strong winds at all levels will be over the Texas and Oklahoma
Panhandles today.  KAMA 88D has been consistently sampling southwest
winds of 50 kt or higher for the past several hours between 1500 and
9000 feet above the surface.  With continued support from incoming
500 mb jet streak of 100 kt or more, we have a high degree of
certainty that surface winds of 35 mph or more, with occasional gusts
of 45 to 55 mph, will occur across western and south-central parts of
the Texas Panhandle today, where the wind advisory issued yesterday
has been laid out.  Areas of blowing dust are expected, with
visibilities perhaps as low as one mile.

Respectable warmup is expected today due to compressional warming
from downsloping west and southwest winds, in spite of passage of
Pacific cold front.  Polar cold front passes tonight, holding
maximum temperatures on Wednesday mainly in the 40s.  The dry post-
frontal air will allow for cold nights, especially Wednesday night
and Thursday night, with lows mainly in the 15 to 25 degree range.

Highly amplified mid-level flow will hold daytime highs below normal,
primarily in the 40s, Thursday through Saturday, with warmer
conditions expected Sunday and Monday.  All pops zero.  03


Elevated fire weather conditions are expected across all sections of
the Texas and Oklahoma Panhandles today as relative humidity values
fall into the 16 to 20 percent range. No elevated or critical fire
weather conditions are expected Wednesday through Monday.  03
