Tranquil weather will prevail across the fcst area tonight through
Tuesday night. On Wednesday, a surface trough of low pressure will
begin to strengthen over ern CO and ern NM, resulting in an
increase in surface winds across roughly the western half of the
area. High level clouds will also be on the increase ahead of the
next vigorous and fast moving upper level shortwave trof. This
particular feature is progged to track across the central Rockies
and into the central plains Thursday and Thursday night. This
forecast path lends to dry slotting for the OK and TX Panhandles
along with windy conditions. The corresponding cold front will
move through the region late Thursday night and Friday morning
with sharply cooler temperatures for Friday and Saturday, then
rebounding late in the weekend into early next week. The 12Z GFS
has trended towards the majority models with respect to handling
another upper level shortwave trof for Sunday and Sunday night.
Now all models are dry with this system. Have removed pops for
this time period.
Critical fire weather conditions will continue until near sunset
this evening across all of the Oklahoma Panhandle and most of the
Texas Panhandle due to north winds of 20 to 25 mph with higher
gusts along with minimum relative humidity values of 10 to 15
percent. A Red Flag Warning is in effect until 6 PM for this area.
In addition, elevated fire weather conditions will continue
across the far southeast Texas Panhandle until near sunset this
evening due to north winds of 20 to 25 mph with higher gusts along
with minimum relative humidity values of 15 to 20 percent.
Critical fire weather conditions will likely develop Thursday
afternoon across most of the Oklahoma and Texas Panhandles due to
strong winds and low relative humidity values. Elevated fire
weather conditions will also be possible during the afternoons on
Wednesday and Friday across parts of the area due to dry west
winds Wednesday and dry northwest winds Friday along with low
relative humidity values.
