...NO CRITICAL AREAS...
No changes have been made to the ongoing forecast.
Gusty winds and relative-humidity values in the 20 and 30 percents
are still expected across portions of the southern High Plains
today. However, fuels still look to remain unreceptive for large
fires. Thus, no changes have been made to the forecast.
.PREV DISCUSSION... /ISSUED 0204 AM CST Sat Dec 10 2016/
With quasi-zonal flow aloft across much of the CONUS, a low
amplitude trough with attendant mid/upper-level speed maximum is
forecast to advance eastward from the West Coast to the central
Rockies through the period. A surface lee trough will develop across
the central and southern High Plains by this afternoon in response
to the large-scale ascent preceding the upper trough/speed maximum.
...Portions of the Southern High Plains...
Locally strong westerly winds of 15-25 mph will occur across mainly
eastern NM and the western TX/OK Panhandles this afternoon as the
surface lee trough strengthens. Downslope trajectories will
encourage some low-level warming/drying of an antecedent cold
airmass. However, RH values are forecast to become only marginally
lowered, generally remaining at or above 20 percent. Furthermore,
guidance continues to suggest fuels will not be overly receptive to
large fire starts. Therefore, no elevated area appears warranted.
